Bypass Notches Sheet Hlau Stamping Tuag Tsim Lub Hom Phiaj: Tsis Xav Tau

Dab tsi Bypass Notches Yog thiab Vim Li Cas Lawv Tseem Ceeb hauv Kev Tsim Tuag

Thaum koj hnov ​​ib tug neeg nug "dab tsi yog stamping" nyob rau hauv cov ntsiab lus ntawm kev vam meej tuag, cov lus teb ib txwm voj voog rov qab mus rau ib qho kev muaj tiag: ib lub strip ntawm cov khoom txav mus los ntawm ntau qhov chaw, thiab txhua qhov kev txiav los yog tsim ntawm ib lub chaw nres tsheb yuav tsum muaj kev nyab xeeb dhau los ntawm txhua qhov chaw nres tsheb tom qab.

Dab tsi yog Bypass Notches hauv Progressive Die Strips

Bypass notches yog me me, txhob txwm tshem tawm cov khoom ntawm cov chaw tshwj xeeb raws li cov cab kuj strip. Lawv txoj hauj lwm yog ncaj nraim: tso cai rau yav dhau los blanked, pierced, los yog tsim cheeb tsam ntawm lub sawb kom tshem tawm cov khoom seem - punches, tuag nyees khawm, lifters, thiab tsim geometry - raws li lub strip nce mus rau ib lub suab ntev rau pem hauv ntej.

Xav txog qhov kev vam meej stamping tuag nrog yim chaw nres tsheb. Txhua tus xovxwm stroke pub lub sawb rau pem hauv ntej los ntawm kev ncua deb. Cov yam ntxwv tsim los ntawm chaw nres tsheb ob yuav tsum dhau los ntawm chaw nres tsheb peb, plaub, tsib, thiab dhau mus yam tsis muaj kev sib tsoo nrog cov cuab yeej. Bypass notches carve tawm txoj kev clearance uas ua rau qhov no ua tau.

Lub bypass notch yog ib qho kev txiav tawm hauv cov khoom thauj khoom ntawm cov txheej txheem stamping tuag uas tiv thaiv cov txheej txheem yav dhau los los ntawm kev cuam tshuam nrog cov cuab yeej qis qis raws li cov sawb pub rau pem hauv ntej.

Vim Li Cas Txhua Txoj Kev Tuag Yuav Tsum Tau Bypass Notches

Qhov tseem ceeb engineering rationale nqes mus rau kev cuam tshuam kev tiv thaiv. Nyob rau hauv daim ntawv hlau stamping, cov cab kuj sawb - cov khoom siv ntxiv uas tuav cov khoom ua ke thaum lawv mus rau qhov chaw nres tsheb - yuav tsum nyob twj ywm suab thaum noj kom huv si los ntawm txhua qhov chaw nres tsheb tuag. Tsis muaj bypass notches, lub sawb sib tsoo nrog punches los yog tsim geometry ntawm cov chaw nyob ib sab, ua rau misfeed, buckling, slug rub, los yog outright tuag puas.

Ib qho yooj yim stamping lub ntsiab lus ntawm qhov teeb meem: sawb mus rau pem hauv ntej, cov khoom ua haujlwm yav dhau los nkag mus rau qhov chaw nyob los ntawm cov cuab yeej nquag, thiab qee yam tawg. Lub hom phiaj ntawm bypass notches hauv stamping tuag yog kom tshem tawm qhov kev sib tsoo ua ntej nws pib.

Raws liArt Hedrick sau ntawv hauv Tus Fabricator, tsis zoo sawb noj nyob rau hauv kev loj hlob tuag ua rau tuag thiab xovxwm puas, seem, kev nyab xeeb kev nyab xeeb, thiab downtime. Bypass notches yog ib qho ntawm cov cuab yeej tsim qauv tseem ceeb uas tiv thaiv cov kev ua tsis tiav no ntawm cov txheej txheem strip - ntev ua ntej tuag puas tau khiav hauv kev tsim khoom.

Dab tsi yog hlau stamping tsis txhim khu kev qha sawb? Nws yog khawb, rov ua dua, thiab cov cuab yeej tawg. Tau txais bypass thais tsim txoj cai los ntawm qhov pib tshem tawm ib pawg ntawm cov teeb meem uas tsis muaj qhov hloov pauv xovxwm tuaj yeem kho tom qab qhov tseeb.

Yuav ua li cas Bypass Notches Tswj Sawb Progression hauv Progressive Tuag

Txhua qhov kev tuag zuj zus ua haujlwm ntawm ib qho tsis yog- txoj hauv kev sib tham: lub sawb txav mus rau tom ntej ntawm qhov chaw ruaj khov - lub suab - thiab txhua qhov tshwj xeeb twb tau txiav los yog tsim yuav tsum dhau los ntawm txhua qhov chaw nres tsheb hauv qab yam tsis muaj dab tsi tsoo. Covhlau stamping txheej txheemcia siab rau lub suab ntawd. Thaum koj rhuav nws, koj rhuav tuag.

Bypass notches yog cov txheej txheem uas ua kom lub suab tsis zoo. Lawv tshem tawm cov khoom siv los ntawm cov khoom thauj khoom ntawm cov chaw raug kom ua haujlwm geometry yav dhau los tshem tawm cov cuab yeej hauv qab. Lub logic yog qhov yooj yim, tab sis qhov kev ua tiav yuav tsum tau ua tib zoo tshuaj xyuas ntawm txhua qhov chaw nres tsheb cov cuab yeej lub hnab ntawv txheeb ze rau lub sawb txoj kev taug kev.

Strip Feed Mechanics thiab Chaw Nres Nkoj Clearance

Nyob rau hauv cov txheej txheem stamping, lub coil feeder nce lub sawb los ntawm ib qho kev ncua deb ntawm ib lub xovxwm stroke. Lub suab ntawd yog qhov chaw nruab nrab - mus rau - nruab nrab ntawm qhov nruab nrab ntawm qhov chaw nyob ib sab hauv qhov kev teeb tsa strip. Txhua lub sij hawm lub strip indexes rau pem hauv ntej, txhua feature upstream - pilot qhov, blanked opens, tsim tabs, kos khob - hloov ib qho chaw nres tsheb ze rau ntawm qhov tawm.

Ntawm no yog lub ntsiab lus tseem ceeb: qhov tsim tshwj xeeb tsim ntawm chaw nres tsheb peb yuav lub cev nyob ntawm qhov chaw nres tsheb plaub thaum lub sijhawm xovxwm tom ntej, chaw nres tsheb tsib ntawm tus mob stroke tom qab ntawd, thiab lwm yam. Yog hais tias ib qho chaw nres tsheb hauv qab muaj lub punch, tuag khawm, lossis lifter rail uas nyob tib qhov chaw ntsug lossis sab nraud raws li qhov dej ntws ntws, cov sawb tsis tuaj yeem noj tsis muaj kev sib tsoo.

Thaum lub sij hawm kev npaj strip layout, tus neeg tsim qauv tsim tawm lub hnab ntawv cov cuab yeej ntawm txhua qhov chaw nres tsheb - peb - qhov chaw seem uas xuas nrig ntaus, tsim cov hlau, thiab cov ntaub qhwv siab nyob thaum lub sij hawm tag nrho cov xovxwm. Txhua qhov chaw uas cov khoom siv strips sib tshooj nrog lub hnab ntawv, muaj ib qho kev cuam tshuam. Txhua cheeb tsam cuam tshuam xav tau ib qho bypass notch.

Carrier strip dav plays lub luag haujlwm ncaj qha ntawm no. Cov neeg nqa khoom dav dua muab cov khoom siv ntau dua rau qhov tsis muaj kev cuam tshuam cov qauv kev ncaj ncees, tab sis lawv haus ntau coil Tshuag. Cov nqaim nqaim txwv qhov tob tob npaum li cas tuaj yeem txuas ntxiv ua ntej ua rau lub sawb tsis muaj peev xwm noj. Cov txheej txheem tuag sib npaug cov kev txwv no thaum ntxov ntawm tus qauv tsim.

Yuav Ua Li Cas Bypass Notches Tiv Thaiv Sawb Buckling thiab Misfeed

Yuav ua li cas thaum bypass notches ploj lawm los yog undersized? Cov hom tsis ua hauj lwm ua ke sai sai:

• Tshem tawm cov lifters.Thaum cov khoom sib tsoo nrog lub downstream punch lossis tuag khawm thaum pub, lub sawb tau raug thawb mus rau sab saud lossis sab xis. Nws lifts tawm lub lifter rails, poob nws txoj kev coj los ntawm kev tuag.
• Buckling ntawm chaw nres tsheb.Lub feeder thawb lub sawb mus rau pem hauv ntej, tab sis lub sawb tsis tuaj yeem hla qhov cuam tshuam. Cov ntaub ntawv compresses thiab buckles ntawm cov kab noj thiab qhov blockage point. Raws li Art Hedrick piav qhia hauvTus Fabricator, round lifters uas tsis txhawb lub sawb kom zoo tso cai rau nws sag thiab quav rau nws tus kheej - ib qho cuam tshuam amplified thaum bypass clearance tsis txaus.
• Slug rub.Ib feem cuam tshuam tuaj yeem rub txiav slugs nce siab thaum lub sijhawm pub noj. Cov slugs no xaus rau ntawm lub ntsej muag tuag thiab tau thwj rau hauv cov khoom tom qab, ua rau cov cuab yeej thiab cov khoom puas.
• Progressive feed yuam kev.Ib qho kev cuam tshuam me me ntawm ib lub chaw nres tsheb tsim ib qho luv luv - pub. Qhov kev ua yuam kev ntawd ua rau pem hauv ntej thiab sib xyaw ua ke ntawm txhua qhov chaw nres tsheb tom ntej, ua rau qhov chaw tsav tsheb tsis zoo, txiav kom tsis sib haum, thiab tsim cov yam ntxwv los tsaws tawm - lub hom phiaj. Hauv kev hloov pauv kev ua haujlwm stamping, ib txoj hauv kev zoo sib xws siv - qhov chaw yuav tsum tshem cov cuab yeej ntawm cov chaw nres tsheb, txawm hais tias lub tshuab thauj khoom sib txawv.

Cov kev ua tsis tiav no tsis tshua tshwm sim raws li ib qho kev sib tsoo loj heev. Feem ntau, lawv tshwm sim raws li maj mam nce burr, sib cuam tshuam misfeed tswb, los yog unexplained variation nyob rau hauv ib feem qhov ntev - tag nrho cov tsos mob ntawm kev cuam tshuam uas tsim nyog bypass notch tsim yuav tau tshem tawm.

Placement Logic nyob rau hauv txoj kev Strip Layout

Kev txiav txim siab qhov twg bypass notches koom yog ib qho kev xyaum ua haujlwm ua ntu zus. Koj tsis tuaj yeem hla nws. Cov txheej txheem kev txiav txim siab ua haujlwm los ntawm qhov chaw nres tsheb strip layout los ntawm chaw nres tsheb, xyuas txhua yam khoom siv tiv thaiv cov khoom siv strips.

1. Daim ntawv qhia txhua lub chaw nres tsheb lub hnab ntawv.Rau txhua qhov chaw tuag, sau tag nrho 3D qhov chaw nyob los ntawm txhua qhov punches, tuag nyees khawm, tsim steels, lifters, thiab siab pads thaum lub sij hawm tag nrho cov xovxwm stroke - tsis yog nyob rau hauv qab qhov chaw tuag.
2. Overlay lub strip profile ntawm txhua txoj haujlwm pub.Taug qab yuav ua li cas cov cab kuj sawb, nrog rau tag nrho nws cov yav tas los txiav thiab tsim nta, tshwm thaum nws tuaj txog ntawm txhua qhov chaw nres tsheb. suav nrog tag nrho cov kab dav dav, cov kab txiav uas twb muaj lawm, thiab txhua qhov tsim geometry uas txuas rau saum toj lossis hauv qab ntawm lub dav hlau sawb.
3. Txheeb xyuas thaj chaw cuam tshuam.Txhua qhov chaw uas cov khoom siv strips sib tshooj nrog lub chaw nres tsheb lub hnab ntawv, kos ib thaj tsam cuam tshuam. Ua tib zoo saib rau ob sab (dhau ntawm txoj kab dav dav) thiab ntsug (saum toj thiab hauv qab lub dav hlau pub) tsis sib haum.
4. Txhais qhov ntsuas geometry rau ib cheeb tsam cuam tshuam.Rau txhua qhov kev tsis sib haum xeeb, txiav txim siab qhov kev tshem tawm yam tsawg kawg nkaus uas yuav tsum tau muab tshem tawm. Ntxiv cov npoo kev nyab xeeb rau tus account rau pub kam rau siab, lateral strip wander, thiab ib qho xovxwm - nrawm- ntsig txog kev hla dhau.
5. Txheeb xyuas qhov kev ruaj ntseg ntawm cov cab kuj.Tom qab tso tag nrho cov bypass notches, paub meej tias cov khoom nqa khoom seem yog cov txheej txheem txaus los pub lub sawb los ntawm kev tuag yam tsis muaj buckling lossis ntau deflection.
6. Muab qhov txiav txiav mus rau qhov chaw nres tsheb tsim nyog.Txiav txim siab seb qhov chaw nres tsheb sab saud yuav txiav txhua qhov bypass thaib. Lub tshuab xuas nrig ntaus stamping ua haujlwm uas tsim cov thais yuav tsum tshwm sim ua ntej lub sawb mus txog qhov chaw nres tsheb uas xav tau kev tshem tawm - qhov zoo tshaj plaws hauv thawj lossis thib ob chaw nres tsheb tuag.

Qhov kev ua haujlwm no siv tau txawm tias koj tab tom tsim kaum- chaw nres tsheb tuag rau ib qho yooj yim bracket lossis peb caug- chaw nres tsheb tuag rau lub tsheb sib txuas. Cov txheej txheem kev tsim khoom stamping xav kom txhua qhov kev txiav txim siab tso rau hauv qhov kev txiav txim siab yuav raug lees paub rau tag nrho txoj kev mus ncig ntawm lub sawb, tsis yog qhov chaw nres tsheb tam sim ntawd.

Geometry tsuas yog ib nrab ntawm zaj dab neeg, txawm li cas los xij. Cov duab thiab qhov loj ntawm txhua qhov thais - duab plaub, angular, lossis radiused - nyob ntawm qhov cuam tshuam tshwj xeeb, cov khoom raug stamped, thiab cov qauv xav tau ntawm cov khoom thauj khoom ntawm qhov chaw ntawd.

Hom Bypass Notches thiab Thaum Yuav Siv Txhua

Tsis yog txhua qhov chaw cuam tshuam zoo ib yam, yog li tsis yog tag nrho cov bypass notches yuav tsum zoo tib yam. Lub geometry ntawm txhua qhov kev taw qhia - nws qhov profile, kev taw qhia, thiab kev kho ntug - ncaj qha cuam tshuam rau kev coj tus cwj pwm noj mov, kev coj noj coj ua ntawm kev ncaj ncees, thiab lub neej ntev - lub cuab yeej siv. Txawm li cas los xij ntawm ntau hom stamping tuag tau tham hauv cov ntaub ntawv siv cuab yeej, bypass thaib kev faib tawm tsis tshua tau txais kev saib xyuas nws tsim nyog.

Peb lub ntsiab lus tseem ceeb npog feem ntau ntawm cov ntawv thov kev tuag: duab plaub, angular (V-zoo li), thiab radiused. Layed nyob rau sab saum toj ntawm qhov kev xaiv geometry yog qhov kev txiav txim siab teeb tsa - seb qhov thais puas yog qhov zoo lossis qhov tsis zoo cuam tshuam rau cov khoom thauj khoom. Txhua qhov sib xyaw ua ke daws qhov teeb meem sib txawv.

Rectangular Versus Angular Bypass Notch Profiles

Rectangular bypass notches yog cov workhorses ntawm strip layout tsim. Lawv muaj qhov ncaj, cov phab ntsa sib luag taw qhia qhov perpendicular mus rau kev coj noj coj ua, tsim kom huv si, lub thawv -zoo li tus txiav tawm hauv cov khoom thauj. Koj yuav pom lawv nyob rau hauv feem ntau stamping tuag qhov chaw cuam tshuam muaj ib qho yooj yim, zoo li profile - xav tias cylindrical punch los yog lub tiaj tus -fab tuag khawm uas xav tau kev tshem tawm thoob plaws qhov dav.

Vim li cas lawv thiaj li ntau? Rectangular notches yog ncaj nraim rau lub tshuab rau hauv cov hlau tuag, yooj yim los soj ntsuam qhov ntev, thiab kwv yees tau hauv lawv tus cwj pwm tshem tawm. Cov xuas nrig ntaus uas tsim lawv yog ib qho yooj yim geometry uas tsis muaj lub kaum sab xis los tswj lossis rov kho dua. Rau cov txheej txheem tshem tawm qhov xav tau qhov kev cuam tshuam zoo - txhais tau tias thiab cov khoom siv sawb tau zam txim, ib daim duab plaub tau ua tiav nrog cov cuab yeej tsawg tsawg.

Angular los yog V-zoo li tus notches ua haujlwm txawv. Thaum qhov cuam tshuam geometry yog kev taw qhia - piv txwv li, ib lub tab tsim uas txuas mus rau ntawm lub kaum sab xis ntawm txoj kev pub noj, lossis qhov xwm txheej uas yuav tsum tau tshem tawm tsuas yog nyob rau ntawm ib sab ntawm tus neeg nqa khoom - angular notch muab lub hom phiaj nyem yam tsis tau tshem tawm ntau tshaj qhov tsim nyog. Lub kaum sab xis tseem faib cov kev ntxhov siab ntau dua li cov ces kaum ntawm lub kaum sab xis ntawm lub kaum sab xis, txo qhov kev pheej hmoo ntawm kev tawg ntawm qhov chaw ciam teb.

Xav txog nws li no: daim duab plaub teb cov lus nug "Kuv xav tau qhov chaw ntau npaum li cas?" thaum angular notches teb "qhov kev taw qhia kuv xav tau qhov chaw ntawd?" Thaum sawb dav yog nruj thiab txhua millimeter ntawm cov khoom nqa khoom tseem ceeb, qhov kev taw qhia ua haujlwm ntawm V- zoo li tus ntiv tes tuaj yeem khaws cov qauv kev ncaj ncees uas tag nrho cov duab plaub yuav cuam tshuam.

Qhov zoo thiab tsis zoo Bypass Notch Configurations

Tshaj li qhov profile zoo, bypass notches poob rau hauv ob qho kev teeb tsa tseem ceeb uas piav qhia txog qhov kev tshem tawm tau ua tiav li cas txheeb ze rau cov cab cab nws tus kheej.

Tsis zoo bypass notches yog dab tsi engineers feem ntau pom thawj - cov ntaub ntawv raug tshem tawm los ntawm nyob rau hauv lub carrier sawb los tsim ib tug qhib uas tooling yuav dhau mus. Lub sawb tuaj txog ntawm qhov chaw nres tsheb nrog ib qho kev txiav tawm uas twb muaj lawm, thiab cov khoom siv qis qis los yog cov khoom siv tuag yog tam sim no - qhov chaw tsis muaj nyob rau lub sijhawm xovxwm. Cov kev tsis pom zoo yog qhov kev ua haujlwm tsis zoo thaum muaj kev cuam tshuam tshwm sim hauv lub sawb tus hneev taw uas twb muaj lawm.

Zoo bypass notches ua hauj lwm txoj kev. Hloov chaw ntawm kev tshem tawm cov khoom siv los ntawm tus neeg nqa khoom, lub strip layout suav nrog cov khoom siv ntxiv - qhov projections lossis tabs uas txuas ntxiv dhau qhov nominal blank outline - tshwj xeeb rau kev xa cov cab kuj nyob ib puag ncig kev cuam tshuam. Lub sawb yog dav dua los yog sib txawv ntawm qhov chaw, tso cai rau nws mus rau txoj kev uas tsis txhob cuam tshuam thaj tsam tag nrho.

Thaum twg koj xaiv ib qho ntxiv? Tsis zoo thiab zoo bypass notches nyob rau hauv daim ntawv hlau stamping tuag pab tib yam clearance muaj nuj nqi, tab sis tus tsim scenarios uas nyiam txhua yam txawv:

• Negative notchesua haujlwm zoo tshaj plaws thaum thaj tsam cuam tshuam me me ntawm cov cab kuj strip dav, thiab tshem tawm cov khoom yuav tsis cuam tshuam kev noj qab haus huv. Lawv yooj yim dua los siv thiab ntxiv tsis muaj qhov dav ntxiv.
• Cov txiaj ntsig zooua qhov tsim nyog thaum thaj tsam cuam tshuam loj los yog hauv nruab nrab, ua cov khoom tshem tawm tsis zoo yam tsis muaj kev puas tsuaj rau cov cab kuj. Lawv xav tau cov coil dav ntxiv - nce cov nqi khoom - tab sis khaws cia cov cab kuj txuas ntxiv.
• Kev siv cov khoom sivfeem ntau qhia txog kev txiav txim siab. Nyob rau hauv siab - ntim ntau lawm qhov twg tus nqi coil dominates, cov neeg tsim qauv nyiam cov ntawv tsis zoo kom muaj qhov dav dav tsawg. Rau qhov nyuaj qhov uas tus neeg nqa khoom muaj kev ncaj ncees yog qhov tseem ceeb, qhov zoo ntawm qhov kev teeb tsa ua kom pom tseeb cov khoom siv ntxiv.

Kev nkag siab qhov tsis zoo thiab qhov zoo bypass notches hauv cov ntawv hlau ua stamping tuag yog qhov tseem ceeb rau kev txiav txim siab txog kev txiav txim siab. Qhov kev xaiv yeej tsis yog geometric nkaus xwb - nws qhia txog qhov sib npaug ntawm cov khoom siv, lub zog ntawm lub cev, thiab kev cuam tshuam tshwj xeeb uas xav tau kev tshem tawm.

Radiused Notch Geometry kom txo kev ntxhov siab

Lub kaum sab xis sab hauv yog yeeb ncuab ntawm kev siab - nrawm nrawm noj. Txhua lub ces kaum sai sai hauv ib qho bypass notch ua raws li kev ntxhov siab nce siab - ib qho taw tes uas cyclic loading thaum lub sij hawm pub ceev ceev - thiab - nres kev tawm suab kom txog thaum cov khoom qaug zog thiab tawg. Thaum lub sij hawm sim ntawm qeeb nias ceev, cov ces kaum muaj sia nyob zoo xwb. Ntawm 600 strokes ib feeb hauv kev tsim khoom, lawv dhau los ua cov ntsiab lus tawg.

Radiused kev hloov pauv ntawm cov ces kaum faib qhov kev ntxhov siab dhau ntawm thaj chaw loj dua, ua rau kom lub strip lub neej qaug zog ntawm qhov nrawm. Lub vojvoog tsis tas yuav loj - txawm tias ib qho me me ntawm txhua lub ces kaum sab hauv tuaj yeem muab cov lej pub noj ua ntej tsis ua haujlwm. Lub vojvoog tshwj xeeb yog nyob ntawm cov khoom tuab, lub zog tensile, thiab xovxwm ceev, tab sis lub hauv paus ntsiab lus yog universal: tsis txhob tawm hauv lub kaum ntse ntse sab hauv ntawm lub bypass notch uas yuav khiav ntawm tus nqi ntau lawm.

Radiused geometry kuj tseem txhim kho slug ejection los ntawm qhov ntswj punch, txo cov burr tsim ntawm cov npoo npoo, thiab txuas lub neej punch los ntawm kev tshem tawm cov kaum ntse ntse uas hnav ceev tshaj plaws ntawm cov cuab yeej txiav nws tus kheej.

Nyob rau hauv kev xyaum, feem ntau ntau lawm stamping tuag ua ke nrog cov txheej txheem no. Ib txoj hlua khi ib leeg tuaj yeem siv cov duab plaub tsis zoo rau qhov yooj yim punch clearances, angular notches qhov twg sawb dav yog txwv, thiab radiused fab ntawm tag nrho cov ntawm lawv kom ciaj sia nyob rau hauv ceev. Hom notch tsis yog kev txiav txim siab thoob ntiaj teb - nws yog qhov chaw nres tsheb - los ntawm - chaw nres tsheb, cuam tshuam- los ntawm - cuam tshuam kev txiav txim hu tau tsav los ntawm qhov tshwj xeeb geometry txhua qhov chaw nres tsheb yuav tsum meej.

Xaiv txoj cai notch profile thiab configuration tau txais koj clearance. Tab sis kev tshem tawm ib leeg tsis yog tag nrho daim duab - qhov ntev ntawm txhua qhov kev txiav txim siab, kev kam rau siab ntawm nws txoj haujlwm, thiab nws txoj kev sib raug zoo rau kev tsav qhov thiab chaw nres tsheb ciam teb txiav txim siab seb qhov kev tshem tawm no puas ua haujlwm tau zoo nyob thoob plaws ntau lab ntawm cov xovxwm.

Bypass Notch Geometry thiab Dimensional Parameters piav qhia

Clearance tsis muaj precision tsuas yog kwv yees. Ib tug bypass notch uas yog roughly nyob rau hauv qhov chaw thiab kwv yees li qhov loj me me yuav ciaj sia tryout - tab sis ntau lawm ntawm ceev txim rau kwv yees. Txhua qhov kev ntsuas geometric ntawm ib qho bypass notch muaj nyob rau hauv engineering vim li cas, thiab tau txais ib qho ntawm lawv tsis raug nqi koj strokes ib feeb, strip kev ncaj ncees, los yog ob qho tib si.

Nyob rau hauv stamping tuag tsim, qhov ntev specification ntawm bypass notches ua raws li ib tug logic khi ncaj qha mus rau qhov cuam tshuam cheeb tsam lawv ua hauj lwm, cov khoom uas lawv txiav los ntawm, thiab lub positional system uas khaws txhua yam nyob rau hauv kev sau npe. Nov yog dab tsi txhua qhov kev tswj hwm thiab vim li cas nws tseem ceeb.

Tseem ceeb Dimensions thiab Tolerances rau Bypass Notch Design

Peb qhov loj me txhais tau hais tias txhua qhov kev hla hla: qhov tob, qhov dav, thiab kaum lub vojvoog. Txhua tus teb rau qhov sib txawv engineering txwv, thiab txhua tus ua rau muaj qhov sib txawv thaum tsis loj.

Notch qhov tobyog ntsuas perpendicular mus rau kev coj noj coj ua - deb npaum li cas mus rau hauv lub cab kuj strip lub notch extends ntawm lub strip edge. Qhov loj me no yuav tsum tau tshem tawm qhov dav tshaj plaws ntawm thaj chaw cuam tshuam nrog rau cov npoo kev nyab xeeb uas suav nrog cov hlua khi sab nraud thaum pub mis. Yog hais tias lub strip drifts txawm me ntsis tawm - nruab nrab (thiab nws yuav), ib tug thais nrog xoom npoo yuav ib tug notch uas tsis meej meej. Cov kev xyaum zoo ntxiv ib qho npoo tshaj qhov siab tshaj plaws lub hnab ntawv, scaled rau xovxwm ceev thiab feeder raug. Cov xovxwm nrawm dua thiab cov khoom noj tsis tshua muaj tseeb xav tau qhov tob tob dua.

Txawm li cas los xij, qhov tob yog txwv los ntawm cov cab kuj strip dav. Hauv kev tsim cov hlau stamping tuag, tus neeg nqa khoom yuav tsum khaws cov ntoo khaub lig txaus- cov khoom seem tom qab txiav kom pub yam tsis muaj buckling lossis tearing. Cov lus qhia dav dav: qhov tob tob yuav tsum tsis pub tshaj 60-70% ntawm cov cab cab dav dav, tab sis qhov tseeb txwv nyob ntawm cov khoom tuab, lub zog tensile, thiab tus naj npawb ntawm qhov ntsuas ntawm lub strip ntev.

Notch davkhiav parallel mus rau kev coj noj coj ua. Nws yuav tsum yog qhov dav txaus kom qhov kev cuam tshuam tshem tawm qhov thaib hla tag nrho cov hlab ntsha tawg - suav nrog kev hla dhau. Pub kam rau siab yog qhov hloov pauv tseem ceeb ntawm no. Yog hais tias lub feeder overshoots los ntawm ib tug me me ntawm ib qho kev mob stroke, lub notch yuav tsum tseem muab tag nrho clearance ntawm qhov siab tshaj plaws overtravel. Dav kuj yuav tsum tau suav rau lub cev qhov loj ntawm cov cuab yeej cuab tam raug bypassed, ntsuas raws cov axis pub.

Xav txog ib qho punch uas nyob 8 hli raws li kev coj noj coj ua. Qhov dav qhov siab yuav tsum npog qhov 8 hli ntxiv rau ob zaug ntawm kev pub noj siab ntev (ib zaug rau qhov muaj peev xwm tshaj - pub, ib zaug rau qhov muaj peev xwm nyob rau hauv - pub rau cov kab mob stroke dhau los) ntxiv rau cov npoo ntxiv rau cov burr lossis khib nyiab buildup ntawm lub ntsej muag lub ntsej muag.

Lub kaum sab xisnyob rau hauv qhov kev hloov pauv tsis pub dhau qaug zog tawg. Raws liXometry's stamping design guidesau ntawv, tag nrho cov ces kaum ntawm ib tug dawb paug tsim yuav tsum muaj ib tug vojvoog ntawm tsawg kawg yog ib nrab ntawm cov khoom thickness. Rau bypass notches, tib lub hauv paus ntsiab lus siv - ntse sab hauv cov ces kaum mloog zoo rau cyclic kev nyuaj siab thaum lub sij hawm siab - noj ceev, pib tawg uas propagate mus txog rau thaum lub carrier sawb puas. Qhov tsawg kawg nkaus lub vojvoog tau nce nrog cov khoom tuab thiab lub zog tensile, thiab txo qis nrog ductility.

Angular kev taw qhiasiv rau cov uas tsis yog - cov duab plaub. Thaum siv V-zoo li tus lossis kaum sab xis, lub kaum sab xis ntawm cov phab ntsa tsis sib haum rau qhov kev coj noj coj ua txiav txim siab qhov kev tshem tawm tau zoo ntawm cov ntsiab lus sib txawv raws li kev noj mov. Kev taw qhia kom raug kom ntseeg tau tias qhov kev tshem tawm siab tshaj plaws coincides nrog lub sijhawm uas qhov kev cuam tshuam dhau los ntawm qhov ntsuas.

Ntawm no yog qhov tseem ceeb geometric tsis txhua tus kws tsim khoom siv yuav tsum txhais ntawm bypass notch specifications hauv lawv cov ntawv hlau stamping tuag:

• Qhov tob (perpendicular rau pub):Muab cov kev tshem tawm sab nraud dhau los ntawm thaj chaw cuam tshuam loj tshaj plaws, suav nrog cov npoo rau kev coj mus ncig.
• Dav (thaum mus rau pub):Ua kom muaj kev tshem tawm tag nrho thoob plaws tag nrho cov kev noj zaub mov, suav nrog kev hla dhau thiab kev pub noj siab ntev.
• Internal kaum sab xis:Tiv thaiv kom txhob muaj kev ntxhov siab thiab qaug zog tawg ntawm cov khoom nrawm. Yam tsawg kawg ib nrab ntawm cov khoom thickness.
• Angular kev taw qhia:Aligns directional clearance nrog txoj kev txav ntawm qhov kev cuam tshuam rau lub sawb.
• Qhov tob-rau- cab kuj- dav piv:Ua kom muaj kev ncaj ncees ntawm cov khoom thauj khoom tom qab tshem tawm cov khoom siv. Kev txwv sib txawv raws li qib khoom siv.
• Ntug mob thiab nto tiav:Tswj burr loj thiab ntug zoo ntawm tus ciam teb ciam teb, tiv thaiv snag ntsiab lus thaum pub.

Kev sib raug zoo rau Pilot Holes thiab Chaw Nres Tsheb Ciam Tebchaws

Ib tug zoo kawg nkaus dimensioned notch nyob rau hauv qhov chaw tsis ncaj ncees lawm tsis muaj dab tsi. Qhov tseeb ntawm bypass notches hais txog ob lub thauj tog rau nkoj nyob rau hauv txhua qhov kev txhim kho tuag strip layout: pilot qhov chaw thiab chaw nres tsheb centerlines.

Pilot qhov yog tus tswv datum rau tag nrho cov sawb. Txhua qhov tshwj xeeb - blanked opens, tsim geometry, thiab bypass notches - yog positioned txheeb ze rau pilot qhov chaw. Qhov no tseem ceeb vim hais tias tus tsav tus pins lub cev rub lub sawb mus rau kev sau npe tseeb ntawm txhua qhov kev tawm dag zog. Yog hais tias ib tug bypass notch drifts los ntawm nws lub hom phiaj txoj hauj lwm txheeb ze rau lub pilot qhov, nws drifts txheeb ze rau cov cuab yeej nws yuav tsum tau tshem tawm.

Hauv kev xyaum, qhov kev kam rau siab nyob rau ntawm bypass notches yog nruj dua li qhov koj xav tau rau qhov tshwj xeeb uas "tsuas yog" muab tshem tawm. Yog vim li cas ties rov qab mus rau margin tswj. Yog tias qhov ntsuas qhov tob ntawm qhov tob yog tsim los ntawm tus nqi tshwj xeeb xav tias txoj haujlwm zoo meej, thiab txoj hauj lwm notch sib txawv los ntawm ib feem ntawm cov npoo, qhov kev tshem tawm zoo yuav qis dua qhov kev nyab xeeb ntawm qee feem ntawm cov hlab ntsha.

Chaw nres tsheb - mus rau - chaw nres tsheb chaw nres tsheb ua raws li kev xav zoo sib xws. Txhua bypass notch yuav tsum nyob rau hauv thiaj li hais tias nws tag nrho clears lub hom phiaj kev thaiv nyob rau hauv tag nrho cov pub stroke. Qhov ntawd txhais tau hais tias tus thawj ntug ntawm qhov kev taw qhia (hauv kev coj noj coj ua) yuav tsum dhau mus dhau qhov kev cuam tshuam ua ntej lub sawb nres, thiab cov ntug ntawm txoj hlua yuav tsum tsis txhob tuaj txog ntawm qhov cuam tshuam ua ntej lub sawb pib txav mus. Pub-kev taw qhia kev tso nyiaj rau qhov nominal pitch nrug ntxiv rau qhov siab tshaj plaws pub rau ob qho tib si.

Raws li tau tham hauvMetalForming Magazine's strip analysis, pub mis tsis raug- lub sijhawm tso tawm tuaj yeem ua rau lub sawb xaub mus rau pem hauv ntej lossis rov qab tom qab tuav tuav qhib. Qhov no txhais tau tias bypass thaib dav yuav tsum haum tsis yog txhua yam overtravel tab sis kuj muaj peev xwm rau post- tso drift ua ntej pilot engagement. Yog tias qhov nqaim nqaim dhau lawm, lub sijhawm tam sim no tso cov khoom thauj khoom rov qab rau hauv thaj chaw cuam tshuam thaum lub sijhawm tam sim ua ntej tus tsav tus pins xauv lub sawb mus rau qhov kawg.

Rau qhov nyuaj stamping tuag Cheebtsam xws li cams, tsim steels nrog lub ntsej muag angular, los yog ntau-theem punches, txoj kev sib raug zoo ntawm qhov thais thiab qhov cuam tshuam ua peb-dimensional. Lub notch yuav tsum tau tshem tawm qhov dav tshaj plaws cross-section ntawm cov khoom ntawm qhov tshwj xeeb ntsug txoj hauj lwm lub sawb occupies thaum lub sij hawm pub stroke - uas yog txiav txim los ntawm lifter qhov siab, tsis hauv qab tuag center geometry. Cov kws ua haujlwm uas qhov ntev hla qhov kev tshem tawm ntawm qhov kev tuag ntawm qhov kaw tag nrho, tsis yog ntawm qhov siab ntawm lub dav hlau noj, xaus nrog cov ntawv uas zoo txaus rau ntawm daim ntawv tab sis cuam tshuam rau kev xyaum.

Cov qhov ntev thiab qhov chaw tsis muaj qhov ua kom muaj nuj nqis ntawm txhua qhov bypass notch specification. Tab sis tus lej ib leeg tsis suav tias cov ntaub ntawv sib txawv teb li cas rau kev txiav txim siab - ib qho kev teeb tsa uas ua haujlwm zoo kawg nkaus hauv cov hlau me me tuaj yeem tawg siab - lub zog steel lossis gall txhuas ntawm cov npoo npoo.

Khoom siv -Tshwj xeeb Bypass Notch Design Considerations

Ib qho me me ntawm cov hlau me me yuav tsis coj tus cwj pwm zoo ib yam hauv ob-theem steel lossis aluminium. Cov ntaub ntawv qib, tuab, thiab cov khoom siv kho tshuab ncaj qha hloov pauv li cas cov kab nqa khoom xa tawm teb rau cov khoom tshem tawm - nws noj li cas, nws qaug zog li cas, thiab qhov txiav cov npoo tuav li cas ntau pua txhiab tus strokes. Kev kho tag nrho cov ntaub ntawv tib yam yog ib txoj hauv kev ceev tshaj plaws los hloov cov khoom siv strip rau hauv kev mob taub hau.

Txhua yam khoom coj nws tus kheej ua ke ntawm ductility, tensile zog, ua hauj lwm -hardening cwj pwm, thiab cov yam ntxwv saum npoo. Cov khoom no hais qhov tsawg kawg nkaus lub kaum sab xis, qhov tob ntawm cov npoo, qhov kev xav tau ntawm ntug, thiab txawm tias qhov kawg ntawm qhov xav tau ntawm qhov ntsuas qhov ntsuas nws tus kheej. Ntawm no yog yuav ua li cas cov kev hloov pauv ntawm cov khoom siv feem ntau hauv cov ntawv hlau stamping thiab dhau mus.

Me Me Steel thiab Cold Rolled Steel Notch Parameters

Cov hlau me me thiab cov txheej txheem txias dov steel hlau stamping qib (CRS zoo li 1008, 1010, 1018) yog cov ntaub ntawv zam tshaj plaws rau kev tsim cov bypass notch. Lawv kev sib xyaw ua ke ntawm lub zog tensile nruab nrab, zoo ductility, thiab kev txiav txim siab shear tus cwj pwm txhais tau hais tias tus qauv tsim cov cai ua haujlwm yam tsis muaj kev tshwj xeeb.

Rau cov pa roj carbon steel stamping nyob rau hauv cov qib no, lub hauv paus tsis siv huv si:

• Yam tsawg kawg ntawm lub kaum sab xis ntawm sab xis:0.5x khoom thickness. Tus qauv piv txwv no, zoo- tau tsim los ntawm kev lag luam notching cov lus qhia, tiv thaiv kev ntxhov siab yam tsis tas yuav muaj cov fillets dav dav uas siv qhov chaw tshem tawm ntxiv.
• Notch qhov tob margin:Cov txheej txheem kev nyab xeeb tshaj li ntawm lub hnab ntim khoom yog txaus. Cov hlau me me tsis rov qab aggressively, yog li lub sawb zaum kwv yees ntawm lub lifter rails thaum pub.
• Ntug mob:Ib tug huv shear nrog ib txwm burr qhov siab yog tau. Cov hlau me me tsis tawg yooj yim los ntawm tus qauv sheared ntug.
• Tooling nto kho:Cov cuab yeej txheem steels (D2, A2) nrog cov pa saum npoo tiav tuav cov qib no yam tsis muaj txheej txheej tshwj xeeb.

Cov hlau me me ua haujlwm raws li lub hauv paus vim nws tuaj yeem kwv yees tau. Kev ua haujlwm- hardening tus nqi yog nruab nrab, qhov elongation ua ntej tawg yog siab dav, thiab cov khoom tsis sib ntaus koj ntawm qhov chaw ciam teb. Yog tias koj tab tom tsim koj thawj kab layout thiab xav kom validate koj bypass notch logic, stamped steel nyob rau hauv cov qib no yuav nthuav tawm layout yuam kev yam tsis tau ntxiv cov khoom - coj tus cwj pwm teeb meem rau saum.

Siab -Strength Steel thiab AHSS Considerations

Advanced High -Strength Steels hloov cov lej loj heev. Cov ntaub ntawv zoo li Dual-Phase (DP600, DP780, DP980), TRIP steels, thiab Martensitic qib muaj zog tensile ntau dua tab sis txo elongation thiab ductility. Cov cab kuj coj tus cwj pwm nruj dua, qaug zog sai dua ntawm kev ntxhov siab, thiab rau txim rau cov geometry ntse uas cov hlau me me yuav zam tau.

Dab tsi hloov rau bypass notch tsim?

Lub kaum radii yuav tsum nce.Qhov twg cov hlau me me txais lub vojvoog ntawm 0.5x cov khoom tuab, AHSS xav tau ntau dua - feem ntau 1.0x rau 1.5x thickness raws li qhov tsawg kawg nkaus. Raws li tau sau tseg hauv kev tshawb fawb tsheb tsheb, AHSS yuav tsum muaj lub kaum sab xis dav dav los tiv thaiv qhov chaw los ntawm kev sib cais thaum lub sij hawm qaug zog. Tib lub hauv paus ntsiab lus siv rau cov cab kuj strip notches: ntse sab hauv cov ces kaum uas ciaj sia indefinitely nyob rau hauv me me steel yuav pib tawg nyob rau hauv ntau txhiab strokes nyob rau hauv DP980.

Notch dav xav tau kev nthuav dav.AHSS springs rov qab nruj dua tom qab txhua qhov pub-thiab- nres lub voj voog. Lub sawb tsis zaum raws li tiaj tus ntawm lifter rails, thiab nws txoj kev coj tus cwj pwm tsis tshua xav tau. Dav dav bypass notches them nyiaj rau qhov txo qis qhov sib xws, ua kom pom tseeb txawm tias lub sawb tsis zoo tag nrho.

Carrier strip dav yuav tsum tau nce.Vim tias AHSS tsis tshua muaj ductile, cov kab nqa nqa tau yooj yim dua rau kev tawg ntawm qhov chaw nyob hauv qab ntawm lub voj voog ntawm qhov siab - pub mis ceev. Txhawm rau kom muaj kev ncaj ncees zoo ib yam uas cov hlau me me muab rau ntawm qhov dav dav, AHSS strip layouts feem ntau xav tau cov cab kuj dav dua - uas txhais tau tias ntau coil Tshuag thiab cov khoom siv ntau dua. Nws yog ib qho kev sib pauv ncaj qha ntawm txoj hlua khi kev ntseeg siab thiab kev siv cov khoom siv.

Tooling hnav accelerates.Qhov siab dua load thaum xuas nrig ntaus AHSS notches degrades punch edges sai dua. Powdered metallurgy steels lossis carbide-tipped punches tsim nyog rau cov chaw nres tsheb uas txiav siab - cov khoom siv zog ntawm cov khoom ntim ntau lawm.

Aluminium thiab Stainless hlau Adaptations

Aluminium thiab stainless hlau txhua tus qhia txog cov kev sib tw tshwj xeeb uas cov hlau me me thiab txawm tias AHSS tsis tuaj.

Aluminiumyog softer thiab ductile ntau dua steel, uas suab zoo li nws yuav tsum ua kom thais tsim yooj yim dua. Tsis yog. Cov txheej txheem txhuas stamping coj qhov chaw tshwj xeeb - teeb meem kev sib cuam tshuam: galling. Kev tshawb fawb ntawm Oakland University's Center of Advanced Manufacturing thiab Materials tau pom tias cov khoom siv txhuas ua raws li qhov chaw tuag thaum lub sij hawm zawv zawg sib cuag, ua rau khawb ntawm qhov chaw ua haujlwm thiab cov nplaum rau ntawm cov cuab yeej. Ntawm qhov chaw bypass thais, qhov chaw sheared ntug ntawm lub sawb rov ua dua cov khoom siv tuag thaum lub sij hawm pub mis, galling tsim cov deposits uas txo cov kev tshem tawm zoo dhau sijhawm.

Kev tiv thaiv yuav tsum tau polished tooling nto thiab feem ntau nyuaj -chrome lossis TiCN txheej ntawm cov khoom tuag uas nyob ib sab ntawm qhov chaw thais. Cov kev tshawb fawb pom tau hais tias qhov roughness ntawm qhov chaw ncaj qha cuam tshuam rau qhov pib ntawm lub qhov ncauj qhov ntswg - smoother tuag nto (xws li tawv -chromed D6510 cam khwb cia hlau) tiv thaiv galling ntawm kev sib cuag siab dua li lwm yam rougher. Rau bypass notch tooling nyob rau hauv txhuas, qhov no txhais tau hais tias lub punch txiav lub notch thiab ib tug tuag nto ntawm notched sawb slides tiv thaiv yuav tsum tuav ib tug finer deg tiav tshaj steel daim ntaub ntawv thov.

Corner radii ntawm aluminium notches yuav tsum ua siab dav tsis yog vim kev qaug zog tawg (txhuas yog ductile txaus ntawm cov tuab tuab) tab sis vim cov ces kaum ntse tsim burr thiab tearing uas tsim cov khoom xoob lub luag hauj lwm rau galling downstream.

Stainless hlaunthuav qhia kev ua haujlwm- nyuaj nyuaj. Txhua lub voj voog pub plastically deforms tus cab kuj strip me ntsis ntawm tus ciam teb ciam teb. Hauv cov hlau me me, qhov me me deformation stabilizes sai. Nyob rau hauv austenitic stainless qib (304, 316), txhua lub voj voog deformation ua rau lub zos hardness thiab brittleness ntawm ntug ntug. Tshaj li kev tsim tawm ntau pua txhiab tus mob strokes, cov npoo ntawm cov npoo nce zuj zus mus txog thaum micro- tawg tsim thiab nthuav tawm.

Tsim bypass notches rau stainless hlau txhais tau tias accounting rau no cumulative hardening. Loj radii qeeb lub hardening tus nqi ntawm cov ces kaum. Polished thiab coated notch punches ua kom huv shear npoo nrog tsawg dua kev puas tsuaj rau hardening los tsim. Thiab qhov tob ntawm cov npoo yuav tsum suav rau qhov tseeb tias kev ua haujlwm - cov npoo tawv tawv tawv coj txawv ntawm kev mob stroke 500,000 dua li ntawm stroke 5,000.

Cov qauv thoob plaws tag nrho cov ntaub ntawv no zoo ib yam: qhov ntxiv cov khoom sib txawv los ntawm kev coj tus cwj pwm tsis zoo steel - txawm tias los ntawm lub zog siab dua, adhesion tendencies, los yog ua hauj lwm - hardening - qhov ntau conservative koj bypass notch parameters yuav tsum tau. Radius nce, margins loj hlob, nto tiav yuav tsum nruj, thiab cov cuab yeej cov nqi nce raws li.

Tau txais cov khoom siv - cov kev txwv tshwj xeeb txoj cai ua kom cov kab xev noj kom huv. Tab sis txawm tias ib qho kev tsis sib haum xeeb zoo kawg nkaus yuav ua rau muaj teeb meem yog tias tus qauv tsim muaj ib qho ntawm ntau yam kev ua haujlwm tsis raug uas tshwm sim ntau zaus hauv cov plag tsev ntau lawm - yuam kev uas yooj yim zam thaum koj paub tias yuav saib dab tsi.

Feem ntau Bypass Notch Mistakes thiab lawv cov kev tshwm sim ntau lawm

Paub qhov tsis zoo thiab paub qhov tsis raug thaum koj tsis quav ntsej lawv yog ob yam kev paub sib txawv. Thawj lub neej nyob rau hauv lub chaw tsim khoom. Qhov thib ob nyob rau hauv pem teb ntau lawm thaum 2 teev sawv ntxov thaum xovxwm mus ncig ua si ntawm lub tswb tsis zoo rau lub sijhawm thib peb uas ua haujlwm. Feem ntau bypass notch tsis ua hauj lwm tsis tshaj tawm lawv tus kheej thaum sim. Lawv tos kom txog thaum cov xovxwm hits ntau lawm ceev thiab lub sawb tau khiav ntev txaus rau hnav, thermal expansion, thiab cumulative yuam kev los nthuav tawm txhua qhov kev txiav txim siab marginal clearance.

Cov kev ua yuam kev hauv qab no tshwm sim ntau zaus hla kev ua haujlwm stamping ua txhua yam los ntawm cov tsheb kauj vab mus rau precision tuag stamping daim ntawv thov rau cov khoom sib txuas. Txhua tus ua raws li tus qauv zoo ib yam: kev xaiv tsim uas zoo nkaus li siv tau rau ntawm daim ntawv lossis ntawm qhov nrawm nrawm tsim cov txheej txheem tsis ua haujlwm uas tsuas yog ua haujlwm raws li kev tsim khoom tiag tiag.

Undersized Notches thiab Tuag Crash Scenarios

Tsis txaus qhov tob lossis qhov dav yog qhov feem ntau hla dhau qhov yuam kev - thiab yog ib qho kim tshaj plaws. Lub mechanism tsis ua hauj lwm yog deceptively gradual. Ib qho undersized notch tsis ua rau muaj kev sib tsoo tam sim ntawd. Hloov chaw, nws tsim kev cuam tshuam ib nrab: lub strip edge cia li NW nyuam qhuav hu ib tug downstream punch los yog tuag khawm thaum lub sij hawm noj mov. Txhua tus mob stroke tawm ib qho cim me me, ua rau me ntsis burr tso rau ntawm qhov chaw cuam tshuam, thiab tshem tawm cov sawb tom qab los ntawm ib feem ntawm ib millimeter.

Tshaj ntau pua lossis ntau txhiab tus mob stroke, qhov burr deposit loj hlob. Lub lateral displacement compounds. Lub sawb pib luv luv- pub mis los ntawm tus nqi me me dhau los mus rau lub misfeed sensor tab sis loj txaus kom degrade pilot qhov rau npe. Stamping qhov chaw downstream pib qhia qhov dav dav dav - lub kaum sab xis hloov pauv, lub qhov hloov pauv, qhov ntug qhov ntev nkag los ntawm kev ua siab ntev.

Ces qhov kev sib tsoo tshwm sim. Qhov kev ua yuam kev ntawm qhov chaw mus txog qhov chaw tipping uas lub sawb tsis tuaj yeem ua dhau los ntawm kev cuam tshuam. Lub feeder pushes, sawb buckles, thiab cov xovxwm tsav lub Upper tuag rau hauv buckled loj ntawm cov khoom. Qhov tshwm sim: tawg punches, puas tuag nyees khawm, tau qhab nia ua steels, thiab cov sij hawm ntawm unplanned downtime rau disassemble, soj ntsuam, thiab kho.

Dab tsi ua rau qhov kev ua tsis tiav no tshwj xeeb yog kev ntxhov siab yog qhov kev ua tsis tiav tuag tsis tshua muaj pib nrog ib qho kev puas tsuaj loj - lawv txhim kho los ntawm kev hnav khaub ncaws ntau thiab kev tsis sib haum xeeb. Ib qho undersized bypass notch accelerates qhov kev vam meej. Txoj kev kho yog ncaj nraim thaum tsim: ntxiv qhov tob tob tshaj li ntawm lub hnab ntim khoom thiab cov npoo dav tshaj qhov pub kam rau siab. Kev kho tom qab kev sib tsoo yog kim heev: kho qhov tuag, revalidate clearances, thiab tej zaum yuav rework lub notch chaw nres tsheb tooling.

Stress Concentration Failures ntawm High Production Speeds

Ntse sab hauv cov ces kaum ntawm bypass notches yog qhov thib ob feem ntau yuam kev, thiab ib qho uas tsim cov kev ua tsis tau zoo tshaj plaws. Ntawm no yog vim li cas lawv muaj sia nyob sim tab sis tua kev tsim tawm: thaum lub sij hawm tuag sim, cov xovxwm khiav ntawm 20-40 strokes ib feeb. Cov sawb pub qeeb qeeb, maj mam maj mam, thiab ua rau muaj kev ntxhov siab me me ntawm cov ces kaum. Txhua yam zoo li zoo. Cov sawb pub kom huv si, cov khoom tawm tuaj rau spec, thiab cov tuag tau txais kev pom zoo rau kev tsim khoom.

Thaum ntau lawm ceev - 200, 400, 600 strokes ib feeb - physics hloov tag nrho. Txhua lub voj voog pub nrawm nrawm thiab txo qis tag nrho cov sawb loj hauv ib feem ntawm ib pliag. Qhov kev thauj khoom cyclic concentrates ntawm txhua lub kaum ntse ntse sab hauv ntawm txhua qhov bypass notch, txhua qhov stroke. Lub tshuab yog classic qaug zog tsis ua hauj lwm: micro- tawg pib ntawm cov ntsiab lus kev ntxhov siab, nthuav tawm me me txhua lub voj voog, thiab thaum kawg ncav cuag qhov ntev. Cov kab nrib pleb tawg.

Thaum tus cab kuj strips fractures ntawm ib tug bypass thais thaum lub sij hawm ntau lawm khiav, qhov tshwm sim cascade instantly. Cov nqes nqes ntawm cov sawb - tseem txuas rau ib nrab ua tiav cov hlau stamping Cheebtsam - nres. Qhov saum toj kawg nkaus, tseem raug thawb los ntawm feeder, buckles rau hauv qhov tuag. Cov xovxwm yuav voj voog ib lossis ob zaug ntxiv ua ntej lub tonnage monitor lossis misfeed sensor reacts, tsav cov punches rau hauv cov khoom tsis raug thiab muaj feem cuam tshuam cov carbide inserts.

Kev sib txuas ntawm cov ces kaum ntse thiab tawg hauv siab - nrawm stamping yog tsim tau zoo - tsim kev tuag tsis tsim nyog nrog cov kaum ntse ntse lossis hla tam sim - ntu hloov pauv tsim cov ntsiab lus kev ntxhov siab uas ua rau tawg. Bypass notch ces kaum yog tsis muaj kev zam. Qhov kev daws teeb meem yog kev hloov pauv ntawm txhua lub kaum sab hauv, qhov loj me raws li cov khoom tuab thiab lub zog tensile raws li tau piav qhia hauv tshooj geometry saum toj no. Ib qho kev nqis peev me me hauv lub vojvoog sib tsoo thaum lub sijhawm tuag tsim tiv thaiv kev puas tsuaj ntawm cov kab nrib pleb hauv kev tsim khoom.

Carrier Strip Weakening thiab Feed Instability

Qhov sib txawv heev los ntawm undersized notches yog sib npaug txaus ntshai: notches uas tob heev txheeb ze rau carrier strip dav. Thaum tus neeg tsim qauv ntsib thaj chaw cuam tshuam loj thiab teb los ntawm kev txiav qhov kev txhoj puab heev uas siv feem ntau ntawm cov neeg nqa khoom hla -section, cov khoom seem yuav tsis muaj cov txheej txheem nruj kom noj tau zoo.

Raws li Tus Fabricator sau tseg, cov khoom nqa khoom uas tsis muaj zog txaus los txhawb qhov hnyav ntawm cov sawb tsis tuaj yeem noj tau zoo, thiab yog tias cov sawb tsis tuaj yeem noj tau zoo, kev tuag yuav tshwm sim. Bypass notches uas tshem tawm cov khoom siv ntau dhau los tsim qhov xwm txheej no - hauv zos tsis muaj zog seem uas sag ntawm lifter rails, oscillate thaum lub sij hawm pub mis sai, los yog flex tom qab txaus kom tsis txhob pilot kev koom tes.

Cov tsos mob ntawm tus kab mob tsis muaj zog yog qhov hloov maj mam thaum xub thawj. Pilots koom nrog inconsistently, ua rau me ntsis variation nyob rau hauv stamped ib feem qhov ntev. Feed sensors tuaj yeem tawm mus ib ntus yam tsis muaj tus qauv meej. Lifter marks tshwm rau ntawm daim kab xev ntawm qhov chaw npaj txhij txog thaum cov seem tsis muaj zog poob mus rau qhov chaw tuag thaum pub. Sij hawm dhau mus, cov khoom thauj tsis muaj zog tuaj yeem tsim kev qaug zog los ntawm kev rov ua dua tshiab, thaum kawg tawg - qhov kawg tshwm sim raws li kev ntxhov siab tsis ua haujlwm, tab sis los ntawm qhov sib txawv kiag li.

Ob qhov kev ua yuam kev ntxiv ua ke cov kev ua yuam kev tseem ceeb no thiab tsim nyog mloog. Tsis quav ntsej cov khoom springback nyob rau hauv notch clearance xam - tshwj xeeb tshaj yog thaum hloov ib tug tuag tsim los ntawm me me hlau mus rau AHSS - ua rau cov notches uas muab txaus static clearance tab sis tsis txaus dynamic clearance thaum lub strips rebounds tom qab txhua lub voj voog pub. Thiab ua tsis tau rau account rau burr kev taw qhia thaum positioning notches tsim ib tug scenario uas bypass notches burr tsim stamping npoo ntsej muag mus rau tuag Cheebtsam, ntes thiab luag thaum pub. Burrs ib txwm ua rau ntawm ib sab ntawm lub npoo sheared; Yog hais tias sab ntawd ntsib qhov kev cuam tshuam qhov thais tau tsim los kom tshem tawm, qhov kev tshem tawm tau zoo raug txo los ntawm qhov siab burr - qee zaum txaus los cuam tshuam.

Nov yog qhov ceev -reference summary ntawm txhua qhov yuam kev ua ke nrog nws qhov kev tsim tawm:

• Tsis txaus notch qhov tob:Progressive burr buildup, gradual positional drift, nws thiaj li tuag poob los ntawm sawb buckling.
• Tsis txaus notch dav:Kev cuam tshuam ib nrab thaum lub sij hawm dhau mus, cuam tshuam lub tswb tsis zoo, kev sau npe tsav tsheb tsis sib haum.
• Ntse Internal ces kaum:Cyclic qaug zog tawg ntawm ntau lawm ceev, kev puas tsuaj sawb tawg, cascade puas tsuaj rau ntau qhov chaw tuag.
• Tshaj qhov tob tob (cov cab kuj tsis muaj zog):Strip sag ntawm lifters, pub instability, intermittent dimensional variation, thaum kawg qaug zog tawg.
• Ignoring springback nyob rau hauv clearance:Dynamic cuam tshuam ntawm rebound, nce sawb rub, nrawm nrawm hnav ntawm qhov chaw nyob ib sab.
• Tsis ncaj burr orientation:Burr- sab ntsej muag cov cuab yeej txo cov kev tshem tawm tau zoo, tsim kom rub thaum pub noj, ua kom hnav ntawm cov khoom tuag.
• Tsis muaj lub vojvoog ntawm qhov ntswj punch ces kaum:Punch ntug ntxov ntxov tawg, loj hlob burr ntawm notch npoo, txo strip qaug zog lub neej los ntawm cov ntug tsis zoo.

Saib ntawm cov piv txwv ntawm kev ua tsis tiav no, tus qauv tshwm sim: txhua qhov yuam kev cuam tshuam nrog tshem tawm cov khoom me me (tsim cuam tshuam), tshem tawm cov khoom siv ntau dhau (ua kom muaj kev ncaj ncees ntawm cov cab kuj), lossis tshem tawm cov khoom tsis raug (tsim kom muaj kev ntxhov siab lossis teeb meem burr). Qhov kev sib tw tsim qauv yog nrhiav qhov nruab nrab hauv av - thiab qhov nruab nrab hauv av hloov pauv nyob ntawm seb lub bypass notch cuam tshuam nrog lwm yam kev tuag zoo li tus tsav lub qhov, lifters, thiab cov txheej txheem tswj cov khoom seem.

Yuav ua li cas Bypass Notches koom nrog lwm yam Progressive Tuag nta

Ib tug bypass notch yeej tsis muaj nyob rau hauv kev sib cais. Nws zaum nyob rau hauv ib qho kev sib koom ua ke ntawm cov yam ntxwv ntawm - qhov chaw tsav tsheb uas pom cov kab nrib pleb, cov lifters uas elevate nws, cov cab cab uas thauj nws, thiab cov kev tswj cov khib nyiab uas tshem cov khib nyiab kom huv si.
