Tsis Zoo Thiab Zoo Bypass Notches Stamping Tuag: Thaum Txhua Yeej

Dab tsi Bypass Notches Ua hauv Progressive Stamping Tuag

Thaum koj khiav ib qho kev tuag zuj zus ntawm kev tsim khoom nrawm, txhua tus mob stroke yuav tsum tsaws hauv qhov chaw zoo. Ib txoj hlua uas rub tawm txawm tias ob peb txhiab ntawm ib nti ua rau cov khoom seem, ua rau cov cuab yeej puas, thiab kaw cov xovxwm. Bypass notches yog ib qho tseem ceeb ntawm kev tiv thaiv kev tiv thaiv qhov tshwm sim, tab sis lawv tau txais kev saib xyuas tsawg dua li cov kws tsav dav hlau lossis cov tshuab pub noj tsis siv neeg hauv kev sib tham tsim kev tuag feem ntau.

Phau ntawv qhia no npogtsis zoo thiab zoo bypass notches nyob rau hauv daim ntawv hlau stamping tuagnyob rau hauv tag nrho cov kev nthuav dav, los ntawm cov txheej txheem yooj yim mus rau kev xaiv cov txheej txheem, cov khoom cuam tshuam, hom tsis ua hauj lwm, thiab cov kev cai tsim. Txawm hais tias koj hu rau lawv lub suab lus, Fabkis txoj kev txiav txim siab, lossis kev hla kev nres, cov hauv paus ntsiab lus tom qab xaiv qhov zoo piv rau qhov tsis zoo geometry txiav txim siab li cas koj lub stamping tuag teeb ua tiav ntau lab lub voj voog.

Dab tsi yog Bypass Notches hauv Progressive Tuag

Bypass notches yog txhob txwm geometric nta txiav rau hauv los yog tsim mus rau lub cab kuj sawb uas koom nrog coj cov khoom nyob rau hauv lub tuag. Lawv lub hom phiaj yog txhawm rau tswj lub cev kev nce qib ntawm txoj hlua khi, tiv thaiv overfeeding thiab xyuas kom txhua qhov chaw nres tsheb tau txais cov khoom ua haujlwm ntawm txoj haujlwm raug.

Xav txog ib txoj kab uas hla mus txog kaum- chaw nres tsheb loj zuj zus. Lub feeder tsis siv neeg thawb nws mus rau ib lub suab ib zaug. Ib tug bypass notch, seb ib tug tab sab laug ntawm lub sawb los yog lub hnab tshos txiav rau hauv lub strip edge, raws li ib tug mating block los yog lub xub pwg nyom nyob rau hauv lub tuag. Qhov kev sib cuag ntawm lub tshuab ua rau lub zog nres, lub cev txwv lub sawb tsis tuaj yeem hla tsis hais tus feeder overshoot lossis tus neeg ua haujlwm yuam kev.

Lawv txawv li cas los ntawm kev tsav lub qhov? Cov kws tsav dav hlau yog cov pins puag ncig uas nkag rau hauv ua ntej- tho qhov kom zoo- khoov txoj hauj lwm tom qab pub ua tiav nws cov hlab ntsha. Lawv kho me me yuam kev. Bypass notches, los ntawm qhov sib txawv, tiv thaiv tag nrho overfeeding ua ntej pilots txawm koom. Ib tug pilot pin loj nrog0.0005 txog 0.001-nti clearancetsis tuaj yeem them nyiaj rau ib daim kab xev uas tau overshot los ntawm ib nrab ntawm lub suab. Qhov ntawd yog txoj hauj lwm ntawm bypass notch: nyuaj mechanical txwv ntawm strip mus deb.

Vim li cas Bypass Notches yog qhov tseem ceeb rau kev sau npe strip

Tsis zoo strip sau npe cascades sai sai. Misaligned hits elongate pilot qhov, uas ntxiv degrades rau npe ntawm downstream chaw nres tsheb. Qhov chaw drift tawm ntawm kam rau ua. Punches tiv tauj cov ntaub ntawv nyob rau hauv qhov tsis ncaj ncees lawm qhov chaw, tsim uneven sab loads uas nti txiav npoo los yog snap punches nkaus. Nyob rau hauv cov xwm txheej hnyav, ib qho kev tshwm sim overfeed tuaj yeem tsoo tag nrho cov seem tuag, ua rau cov nqi kho mob uas lub hli qis ntawm cov khoom txuag.

Lub hom phiaj ntawm bypass notches nyob rau hauv stamping tuag ncua tshaj kev tiv thaiv overfeed. Raws li tau sau tseg los ntawm tus kws tshaj lij tsim kev tuag Art Hedrick hauvTus Fabricator, pitch notches kuj tshem tawm ntug camber los ntawm slit coil Tshuag, tsim kom huv si siv ntug uas tso cai rau lub sawb noj smoothly los ntawm kev qhia. Yog tsis muaj qhov ncaj ncaj, cov khoom siv cambered khi tiv thaiv cov lus qhia, ua rau tsis zoo noj ntev txawm tias niaj hnub servo feeders.

Bypass notches lub cev txwv tsis pub mus ncig ua si kom txhua qhov chaw nres tsheb tau txais cov khoom ua haujlwm hauv txoj haujlwm raug, tsis muaj qhov tseeb ntawm cov khoom noj khoom haus, coil mob, lossis theem kev txawj ntawm tus neeg teb xov tooj.

Peb lub tshuab ua haujlwm ua ke rau kev txhim kho txhim khu kev qha: lub tshuab feeder tsis siv neeg muab qhov kev nce qib nominal, bypass notches tswj qhov siab tshaj plaws mus txawv tebchaws thiab tshem tawm camber, thiab tus tsav pins xa cov ntawv sau npe kawg. Tshem tawm ib qho kev hloov pauv kev pheej hmoo mus rau lwm tus. Thaum tag nrho peb lub luag haujlwm hauv kev sib koom ua ke, lub stamping tuag teeb tswj kev rov ua dua ntawm kev ua haujlwm ntev, txawm tias thaum lub sijhawm teeb tsa thaum feem ntau tuag sib tsoo tiag tiag tshwm sim.

Cov lus nug tseem ceeb rau txhua tus neeg tsim qauv tuag tsis yog seb puas yuav siv bypass notches, tab sis hom twg los siv. Qhov kev txiav txim siab ntawd cuam tshuam txog seb koj puas tawm cov khoom ntawm lub strip (zoo) los yog tshem tawm (tsis zoo), thiab txhua qhov geometry muaj qhov zoo sib xws nyob ntawm qhov dav dav, qhov nrawm, thiab cov khoom siv.

Yuav Ua Li Cas Zoo Bypass Notches Ua Haujlwm thiab Thaum Yuav Siv Lawv

Tso cov khoom ntawm lub sawb es tsis txhob txiav nws tawm tuaj yeem ua rau lub suab tsis zoo rau qhov tshwj xeeb txhais tau tias tswj kev nce qib. Txawm li cas los xij, qhov ntawd yog qhov zoo ntawm kev hla qhov tsis zoo, thiab cov duab geometry tom qab nws daws tau ntau yam teeb meem uas cov pa slug - tsim cov ntawv qhia.

Yuav Ua Li Cas Zoo Bypass Notches Tswj Strip Progression

Ib qho zoo bypass notch yog tsim los ntawm lancing ib feem me me ntawm cov cab kuj strip thiab tsim nws downward (los yog qee zaus upward) los tsim ib lub tab uas tej yaam num tawm ntawm lub dav hlau sawb. Daim duab ib tus nplaig, feem ntau 3 mus rau 6 hli dav thiab projecting 1 mus rau 1.5 npaug ntawm cov khoom thickness hauv qab lub strip nto, oriented perpendicular rau cov kev coj noj. Lub tab tseem txuas nrog rau cov cab kuj ntawm ib qho kawg, tsim kom muaj lub flange cantilevered raws ntug kab txaij.

Thaum lub sij hawm pub kev nce qib, qhov tsim tab no mus rau pem hauv ntej nrog lub sawb kom txog rau thaum nws hu rau lub zog nres lossis lub xub pwg machined rau hauv cov khau qis. Qhov kev sib tsoo lub cev ntawd tso tseg txoj hlua khi ntawm qhov tseeb ntawm qhov tseeb ntawm qhov deb. Lub geometry yog tus kheej - txwv: lub tab tsis tuaj yeem hla qhov nres nres, yog li overfeeding ua mechanically tsis yooj yim sua txawm hais tias lub feeder siv zog npaum li cas.

Vim li cas ho tso cov khoom txuas es tsis txhob xuas nrig ntaus? Cov lus teb muaj ob qho tib si kev ntseeg siab thiab kev ncaj ncees strip. Lub lanced-thiab- tsim tab ua tsis muaj slug. Tsis muaj ib qho me me ntawm cov seem uas yuav tsum tau tawm ntawm qhov qhib qhov tuag, tsis muaj kev pheej hmoo ntawm tus slug raug rub rov qab mus rau hauv qhov tuag kab noj hniav ntawm qhov rov qab stroke. Rau ib tus neeg paub txog kev mob taub hau ntawm slug rub hauv kev ua haujlwm xuas nrig ntaus stamping, qhov kom zoo dua ib leeg ua rau txoj hauv kev.

Lub angular orientation ntawm lub tab tseem ceeb heev. Feem ntau zoo bypass notches yog tsim ntawm 90 degrees mus rau lub strip nto, tab sis me ntsis angular kho ntawm 80 mus rau 85 degrees tuaj yeem tsim ib qho kev txiav txim siab tawm tsam qhov nres. Qhov no ua rau kom muaj zog tuav thiab txhim kho kev tswj kev noj zaub mov ntawm cov ntaub ntawv thicker qhov twg sawb lub zog siab dua.

Cov ntawv thov zoo rau kev tsim qauv zoo

Zoo bypass notches nyob rau hauv daim ntawv hlautsim excel hauv cov xwm txheej tshwj xeeb uas strip kev ncaj ncees thiab kev tswj xyuas cov khoom tseem ceeb. Xav txog ib txoj kab nqaim nqaim, hais 25 mm dav, pub ib qho me me txuas. Txiav ib tug pa thais ntawm ntug tshem tawm ntoo khaub lig-sectional cheeb tsam los ntawm ib tug me me tus cab kuj. Cov khoom ploj ntawd ua rau lub sawb tsis muaj zog ntawm qhov taw tes uas pub quab yuam kom muaj zog, caw buckling lossis tearing thaum lub sijhawm ua haujlwm siab -.

Lub lance-thiab- daim ntawv thaib zam qhov no tag nrho. Cov khoom nyob twj ywm hauv cov cab kuj. Hla-sectional lub zog tseem nyob ruaj khov. Cov flange tsim tau ua kom nruj rau cov hlua hauv zos, uas pab txhawb kev noj qab haus huv los ntawm kev nqa cov hlua, ib qho txiaj ntsig tau sau tseg los ntawm cov kws tsim qauv tuag ua haujlwm nrog ib qho - sab nrauv layouts.

Lub hom phiaj ntawm bypass notches nyob rau hauv daim ntawv hlau txoj kev txuas mus rau seem economics thiab. Txhua slug ib tug tuag tsim ntxiv rau cov ntaub ntawv pov tseg xam. Nyob rau hauv siab - ntim ntau lawm qhov twg cov khoom siv tus nqi dominates ib feem pricing, tshem tawm txawm ib tug me me notch slug los ntawm txhua qhov kev loj hlob multiplies rau hauv ntsuas kev txuag nyiaj ntau tshaj ib lab-stroke khiav.

• Tsis xav tau slug tswj- tshem tawm slug rub txoj kev pheej hmoo thiab tshem tawm qhov xav tau ntawm cov slug clearance channel hauv qhov tuag
• Khaws tus neeg nqa khoom hla-section- tseem ceeb heev rau qhov nqaim strips uas tshem tawm cov khoom yuav cuam tshuam kev noj zaub mov ruaj khov
• Stiffens lub strip hauv zos- cov flange tsim ntxiv rigidity ntawm qhov chaw thais, pab txoj kev taug kev mus los ntawm kev nqa nqa
• Txo cov seem ib qhov zuj zus- tsis muaj cov khoom raug tshem tawm ntawm lub sawb, txhim kho kev siv cov khoom siv ntawm tus nqi - cov haujlwm tseem ceeb
• Kev tsim kho yooj yooj yim ntawm qhov chaw nres tsheb- lance punch thiab tsim seem hloov tag nrho kev txiav- los ntawm kev xuas nrig ntaus nrog slug clearance qhov

Kev tsim qauv zoo ua rau muaj kev txwv. Lub tab tsim yuav tsum tshem tawm lifter mechanisms raws li lub strips nce ntawm strokes. Nyob rau siab -ceev tuag khiav saum 600 strokes ib feeb, downwards - projecting tab tuaj yeem ntes ntawm lifter rails lossis cuam tshuam nrog lub sijhawm nce siab. Cov kev pheej hmoo cuam tshuam no thawb qee cov ntawv thov mus rau lwm txoj hauv kev: tshem tawm cov khoom siv tag nrho los tsim qhov tsis zoo geometry uas cuam tshuam cov neeg tuag los ntawm qhov kev coj ua.

Yuav Ua Li Cas Tsis Zoo Bypass Notches Ua Haujlwm thiab Lawv Lub Zog

Thaum ib lub tab tsim projecting hauv qab lub strip tsim teeb meem clearance ntawm kev kub ceev, qhov kev daws teeb meem flips lub geometry nkaus. Es tsis txhob tso cov khoom ntawm lub sawb, ib qho tsis zoo bypass thais tshem tawm ib qho me me los ntawm ntug kab txaij, tsim kom muaj ib lub hnab tshos uas koom nrog qhov kev ua kom tawv tawv ua rau hauv qhov tuag. Lub sawb nws tus kheej nqa qhov khoob; tus tuag nqa qhov nres.

Mechanics ntawm Negative Bypass Notches thiab tshem tawm cov khoom

Ib qho tsis zoo bypass notch yog tsim los ntawm stamping xuas nrig ntaus ib lub me me los yog trapezoidal seem ntawm ib los yog ob qho tib si ntawm cov cab kuj strip. Lub stamping tuag punches siv rau kev ua haujlwm no feem ntau nqaim, xws li ntawm 3 mus rau 8 hli hauv qhov dav thiab nkag mus rau 2 mus rau 5 hli mus rau hauv kab sawb nyob ntawm qhov dav dav thiab cov khoom tuab. Qhov kev txiav txim ua raws li tib lub tshuab shearing raws li ib qho kev ua haujlwm blanking: lub punch nqis mus rau hauv qhov qhib qhov rooj tuag, cov khoom tawg los ntawm ib qho shear- thiab - tawg ib ntus, thiab ib qho slug cais tawm ntawm lub sawb.

Tus slug ntawd xav tau kev saib xyuas. Ib qho slug feem ntau yog ib daim nyias nyias, qee zaum me me li ob npaug ntawm cov khoom tuab hauv nws qhov nqaim tshaj plaws. shedding xws li ib tug me me reliably yog ib tug paub kev sib tw. Lub slug clearance qhov hauv qab qhov qhib tuag yuav tsum muab lub kaum sab xis txaus, feem ntau yog 0.5 txog 1℃ib sab, txhawm rau tiv thaiv slug stacking. Lub tshuab nqus tsev pab los yog qhov zoo slug ejection los ntawm lub caij nplooj ntoos hlav-loaded kickers yuav tsum tau nyob rau siab- daim ntawv thov ceev uas lub ntiajteb txawj nqus ib leeg tsis tuaj yeem tshem cov slugs sai txaus.

Thaum txiav lub hnab tshos, nws nce mus nrog lub sawb kom txog rau thaum nws mus txog qhov tseem ceeb ntawm cov khoom siv tawv tawv, qhov tseeb - av steel projection mounted hauv cov khau tuag. Tus yuam sij thaiv nkag mus rau hauv lub hnab tshos, thiab cov phab ntsa tom qab ntawm qhov kev sib cuag nrog lub ntsej muag tseem ceeb, halting rau pem hauv ntej strip taug kev ntawm lub suab kom raug. Lub geometry ntawm no tseem ceeb: qhov tob tob yuav tsum tshaj qhov tseem ceeb thaiv qhov projection los ntawm 0.3 mus rau 0.5 hli kom tso cai rau kev sib koom tes huv si yam tsis muaj kev khi, thaum qhov dav dav yuav tsum suav rau kev pub noj siab ntev ntawm lub cev ntxiv rau kev nthuav dav ntawm cov sawb thaum lub sijhawm ua haujlwm ntev.

Angular nyem rau ntawm ntug ntawm qhov thais, feem ntau 3 mus rau 5 degrees, tso cai rau lub sawb caij hla lub qhov tseem ceeb thaum lub sij hawm pub kev nce qib yam tsis tau ntes. Lub trailing ntug tseem square los yog me ntsis undercut, tsim lub ntsej muag zoo nres uas ntes sawb tsab ntawv tsa suab. Kev tshem tawm ntawm qhov tseem ceeb ntawm ob sab thiab cov phab ntsa thais feem ntau khiav ntawm 0.05 mus rau 0.10 hli ib sab, nruj txaus los tiv thaiv lateral drift tab sis xoob txaus kom tsis txhob khi raws li bypass notches burr tsim stamping residue accumulates ntawm kev sib koom ua haujlwm ntev.

Qhov kev sib raug zoo ntawm qhov ntsuas qhov ntsuas qhov siab thiab qhov siab burr yog ncaj qha. Ib tug dull notch punch tsim ib tug rollover rau sab nkag thiab ib tug pronounced burr nyob rau hauv tuag sab ntawm qhov txiav. Qhov burr tej yaam num rau hauv lub hnab tshos, zoo txo ​​nws txoj kev ua haujlwm tob. Tshaj li ntau txhiab tus mob stroke, kev txhim kho burr nce tuaj yeem tiv thaiv qhov thaiv qhov tseem ceeb ntawm qhov rooj zaum, degrading qhov tseeb ntawm kev sau npe. Kev tuav cov punch kom raug-rau- tuag tshem tawm, feem ntau yog 5 mus rau 10 feem pua ​​​​ntawm cov khoom tuab ntawm ib sab rau cov hlau me me, ua kom cov burrs nyob rau hauv qhov kev txwv tsis pub siv thiab ncua sijhawm txij nkawm.

Qhov twg Negative Notch Designs ua tau zoo tshaj plaws

Cov kev tsis zoo tsis zoo nyob ntawm ntug strip es tsis pom hauv qab ntawm lub dav hlau sawb. Tsis muaj dab tsi protrudes. Lub sawb tseem nyob tiaj tus, uas txhais tau hais tias cov tsheb thauj khoom, cua tshuab- tawm tshuab, thiab cov khoom siv hluav taws xob tshawb pom txhua qhov ua haujlwm yam tsis muaj kev cuam tshuam. Rau cov neeg tuag khiav saum 600 strokes ib feeb, qhov profile tiaj tus no yog qhov tseem ceeb.

Xav txog ib lub dav carrier sawb, 75 hli los yog ntau tshaj hla, pub rau lub tsheb loj loj. Tshem tawm 4 hli los ntawm txhua tus ntug rau cov hnab ris tsis tshua muaj feem cuam tshuam rau tus neeg nqa khoom thauj khoom -cov kabmob hla ntu. Lub sawb khaws cov qauv kev ncaj ncees thaum tau txais kev tswj xyuas nruj los ntawm kev sib koom ua ke zoo nrog cov ntsiab lus tseem ceeb. Cov khoom tshem tawm tsim ib qho chaw so uas qhov tuag qhov projection nkag mus, qhov tseem ceeb tsim qhov nres geometry rau hauv cov cuab yeej es tsis yog rau hauv cov sawb.

Txoj kev no tseem muab kev txiav txim siab nres ntau dua. Ib qho tseem ceeb thaiv nkag mus rau hauv lub hnab ntim machined koom nrog kev sib cuag ntawm lub ntsej muag thoob plaws phab ntsa, faib cov tub rog pub rau hauv cheeb tsam loj dua li ib lub tab ntaus lub xub pwg nyom. Qhov kev sib cuag ntawd tiv thaiv kev deformation zoo dua thaum lub sij hawm tam sim ntawd deceleration ntawm ib tug hnyav sawb ntawm ceev.

• Flat strip profile- tsis muaj qhov projecting tabs cuam tshuam nrog lifters, sensors, los yog siab -ceev sawb thauj mechanisms
• Aggressive feed capture- tag nrho lub ntsej muag kev sib cuag ntawm qhov tseem ceeb thaiv thiab cov phab ntsa ntawm phab ntsa faib ua kom tsis txhob muaj zog, txo cov deformation hauv zos
• Tshem tawm ntug camber- txiav txiav txiav cov npoo tsis sib xws, ua kom huv si rau cov lus qhia
• Dual{0}} ntawv sau npe- txiav txiav rau ntawm ob lub strips thiab siv cov khoom tseem ceeb ua ke tiv thaiv kev hloov pauv ntawm txoj hlua khi thaum lub sij hawm stamping xuas nrig ntaus
• Tau tshaj - ceev automation- tsis muaj cov yam ntxwv tsim los ntes, khoov, lossis qaug zog ntawm tus nqi siab
• Thawj - ntaus nres muaj peev xwm- qhov chaw nres tsheb ua haujlwm ua tus thawj coj -ntug locator thaum pib teeb tsa tuag, txo kev pheej hmoo ntawm ib nrab- hits lossis xoob seem ntawm kev pib

Kev lag luam tawm - tawm yog qhov tseeb: cov ntawv tsis zoo siv cov khoom siv sawb, tsim cov slugs uas yuav tsum tau tswj hwm, thiab qhia txog kev txiav cov npoo uas hnav dhau sijhawm. Rau cov strips dav dua qhov twg cov kev nplua no tseem tswj tau, qhov kev ntseeg siab thiab kev sib raug zoo ntawm qhov kev tsim no ua rau nws yog qhov kev xaiv tseem ceeb hauv kev ua haujlwm siab - ntim nce zuj zus. Cov lus nug tsis yog hom twg yog qhov zoo tshaj plaws, tab sis cov txheej txheem ntawm kev txwv koj daim ntawv thov tshwj xeeb imposes, qhov kev txiav txim siab pom tseeb dua thaum ob lub geometries muab tso rau ib sab.

Zoo vs Negative Bypass Notches Xaiv Phau Ntawv Qhia

Muab ob qho tib si geometries ib sab ntawm ib sab qhia tias kev xaiv ntawm lawv tsis tshua muaj txog ib qho zoo dua li lwm tus. Nws yog hais txog kev sib piv cov qauv tsim rau ib qho kev sib xyaw ua ke ntawm sawb dav, kev tsim khoom ceev, cov khoom siv coj mus kuaj, thiab cov khoom siv khib nyiab. Cov lus hauv qab no suav nrog qhov sib txawv ntawm kev siv tshuab thiab kev ua haujlwm sib txawv rau hauv ib qho kev siv koj tuaj yeem siv thaum lub cuab yeej thiab tuag stamping tsim tshuaj xyuas.

Positive vs Negative Bypass Notches Muab piv

Ntau qhov sib txawv hauv cov lus no ua rau muaj kev cuam tshuam loj heev rau qhov kev txiav txim siab tsim qauv kawg. Sawb dav feem ntau yog thawj lim. Thaum koj ua haujlwm nrog tus nqa nqa nqaim dua 30 hli, tshem tawm txawm tias 3 mus rau 4 hli los ntawm ntug rau qhov tsis zoo thaib siv qhov feem pua ​​​​ntawm cov hlaws dai. Pub quab yuam ua kom pom tseeb ntawm qhov chaw txo qis, thiab qaug zog tawg ua rau muaj kev pheej hmoo ntau lawm. Ib qho txiaj ntsig zoo sidesteps qhov no tag nrho los ntawm kev khaws cov khoom hauv qhov chaw.

Ceev yog qhov thib ob tseem ceeb lim. Siab-kev ua haujlwm ceev hlau ua haujlwm siab tshaj 600 strokes ib feeb xav tau lub tiaj tus profile. Txhua millisecond ntawm lifter mus ncig teb chaws suav, thiab ib lub tab projecting hauv qab lub strip tuaj yeem ntes, khoov, lossis qaug zog hauv txoj hauv kev uas sib xyaw ua ke ntawm cov kab mob stroke siab. Cov ntawv tsis zoo khaws txhua yam dej ntws tawm, uas yog vim li cas lawv tswj hwm lub tsheb thiab cov khoom sib txuas stamping kab uas lub voj voog lub sij hawm ntsuas hauv feem ntawm ib thib ob.

Kev tuav cov khib nyiab yog qhov sib txawv thib peb uas feem ntau qhia qhov sib npaug. Ib tug tsis zoo notch tsim ib tug slug rau txhua txhua stroke. Tshaj li ib lab- voj voog ntau lawm khiav, cov me me slivers sau. Yog hais tias lub slug clearance system tsis txawm luv luv, slugs pawg nyob rau hauv lub tuag qhib, thaiv qhov tseem ceeb thaiv kev koom tes, thiab ua rau misfeeds. Cov khw muag khoom nrog kev tswj hwm slug zoo heev nqus tau qhov kev nplua no yooj yim. Cov khw khiav ntshiv nrog tsawg kawg kev tu ncua sij hawm yuav pom cov txiaj ntsig zoo dua kev zam txim.

Ntug camber, mob taub hau tsis tu ncua nrog slit coil Tshuag, ntxiv lwm qhov kev xav. Tsis zoo bypass notches nyob rau hauv daim ntawv hlau txoj kev stamping tuag inherently trim lub strip ntug, tshem tawm camber qhia thaum lub sij hawm coil slitting. Cov txiaj ntsig zoo tsis muaj kev kho zoo li no, yog li yog tias koj cov khoom xa tuaj tuaj nrog cov npoo tsis sib haum, koj yuav tsum tau ntxiv qhov chaw nres tsheb sib cais los yog lees txais cov khoom noj tsis ruaj khov uas camber qhia.

Cov Kev Cai Xaiv Cov Kev Ntsuam Xyuas rau Kev Tuag Designers

Tsis yog qhov hnyav tag nrho ib txhij, cov cuab yeej paub txog thiab cov neeg ua haujlwm tuag stamping ua haujlwm los ntawm cov txheej txheem kev txiav txim siab ua ntu zus. Txhua qhov kev ntsuas yuav tshem tawm ib qho kev xaiv lossis nqaim lub teb. Siv daim ntawv txheeb xyuas no thaum lub sij hawm kev tshuaj xyuas strip layout kom tuaj txog ntawm txoj cai notch geometry systematically.

1. Sawb dav thiab carrier hla ntu- Ntsuas qhov dav ntawm cov cab kuj tom qab ib feem geometry yog zes. Yog tias tus neeg nqa khoom tsawg dua ob zaug ntawm qhov kev npaj qhov tob tob ntawm txhua sab, qhov zoo thaib khaws cia cov qauv kev ncaj ncees. Cov neeg nqa khoom dav nrog cov khoom siv txaus tuaj yeem zam qhov kev tshem tawm uas xav tau los ntawm qhov tsis zoo.
2. Khoom hom thiab thickness- Cov ntaub ntawv nyuaj ua rau muaj burr ntau dua ntawm qhov tsis zoo thaib txiav, ua kom nrawm nrawm rau hnav. Cov ntaub ntawv nyias nyias hauv qab 0.5 hli muaj kev pheej hmoo tawg ntawm cov tabs tsim hauv cov qauv zoo. Sib piv cov thais hom rau li cas koj cov alloy tshwj xeeb coj nyob rau hauv shear lossis dabtsi yog khoov ntawm qhov kub thiab txias.
3. Ntau lawm ceev- Yog tias koj lub hom phiaj siab tshaj 500 mus rau 600 strokes ib feeb, ua rau tsis zoo rau lawv qhov profile. Hauv qab qhov pib, ob hom ua tau txais kev ntseeg siab muab lub sijhawm lifter haum rau txhua qhov tab projection.
4. Part geometry txwv- Xyuas seb puas tsim cov yam ntxwv, kos chaw nres tsheb, lossis cam-tsav kev ua haujlwm nyob ze ntawm ntug ntug tsis sib haum nrog qhov chaw nyob. Qhov zoo tabs project hauv qab ntawm lub sawb thiab tuaj yeem cuam tshuam nrog cov khoom seem tuag.

Tsim Cov Lus Qhia rau Bypass Notch Sizing thiab Placement

Xaiv txoj cai notch hom yog ib nrab ntawm kev sib ntaus sib tua. Lwm ib nrab yog dimensioning thiab positioning nws yog li ntawd lub strips cia siab rau, mob stroke tom qab mob stroke, tsis dhau - txwv tsis pub noj los yog tshaib plab cov cab kuj ntawm cov khoom siv. Cov kev cai sizing no txhais lub hom phiaj tsim rau hauv khw-qhov tseeb hauv pem teb.

Cov cai ntawm Thumb rau Notch Qhov tob thiab dav

Notch qhov tob yog thawj qhov ntev rau pin down, thiab nws ntsuas ncaj qha nrog cov cab kuj dav. Tshem tawm ntau dhau thiab cov sawb buckles nyob rau hauv pub quab yuam. Tshem tawm tsawg dhau thiab qhov tseem ceeb thaiv kev koom tes ua qhov ntiav txaus uas burr buildup lossis thermal expansion defeats nres nyob rau hauv ob peb txhiab strokes.

Rau qhov tsis zoo bypass notches, ib qho pib taw tes yog 15 mus rau 25 feem pua ​​​​ntawm cov sawb dav ntawm txhua sab. Ib tug 60 hli dav cov cab kuj, piv txwv li, txhawb nqa 9 mus rau 15 hli thais hnab ris txiav los ntawm txhua tus ntug thaum khaws cov ntoo khaub lig txaus rau kev noj zaub mov ruaj khov. Narrower strips xav tau ntau qhov feem pua ​​​​tseem ceeb. Hauv qab 30 hli ntawm tag nrho cov sawb dav, koj feem ntau zoo dua nrog ib tug zoo lance - thiab - daim ntawv tsim uas zam cov khoom tshem tawm tag nrho.

Notch dav, ntsuas nyob rau hauv kev coj noj coj ua, yuav tsum ua kom haum rau kev pub noj siab ntev ntawm koj lub cev ntxiv rau cov npoo me me rau kev loj hlob thermal ntawm lub sawb thaum tsim khoom. Ib tug raug servo feeder xa pitch raug nyob rau hauv 0.05 hli tso cai rau ib tug notch dav ntawm qhov tseem ceeb block dimension ntxiv rau 0.15 mus rau 0.25 hli tag nrho. Tighter tshaj qhov ntawd, thiab qhov tseem ceeb thaiv khi rau hauv hnab ris. Dav dav, thiab lub strip overshoos ua ntej ntes.

Lub kaum sab xis sab hauv lub hnab tshos tsis tsim nyog tau txais kev saib xyuas. Ntse sab hauv cov ces kaum ua raws li kev ntxhov siab risers. Txawm tias ib lub vojvoog me me ntawm 0.3 mus rau 0.5 hli ntawm lub kaum ntse ntse tiv thaiv kev qaug zog tawg uas yuav tsis pib tom qab ntau pua txhiab qhov cuam tshuam. Ntawm cov cuab yeej hardened steels siv rau cov blocks tseem ceeb, ib qho sib txuam fillet faib kev sib cuag nrog kev ntxhov siab ntau dua.

Ua tiav cov geometries sab hauv, tshwj xeeb tshaj yog nyob rau hauv cov blocks tseem ceeb thiab tuag inserts, yog qhov twg EDM hlau txiav proves indispensable. Cov cuab yeej txawj ntse thiab cov neeg tsim khoom tuag tuaj yeem ua qhov tseem ceeb thaiv cov ntaub ntawv nrog kev ua siab ntev ntawm ntxiv lossis rho tawm 0.0005 nti, ua rau sab hauv kaum sab xis me me li 0.050 hli nrog cov xaim zoo ntawm kev tswj ceev. Vim tias EDM hlau txiav tom qab kev kho cua sov, qhov tseem ceeb thaiv kev ruaj ntseg ntawm qhov tsis muaj qhov cuam tshuam los ntawm kev ua kom tawv tawv, qhov txiaj ntsig tseem ceeb thaum kev sib koom ua ke geometry yuav tsum nyob twj ywm hauv ntau lab lub voj voog. Taper nyem ntawm 0.25 mus rau 0.5 degrees thov los ntawm EDM hlau kuj tso cai rau cov blocks tseem ceeb rau reground yam tsis hloov qhov kev sib koom tes ntawm lub ntsej muag ua haujlwm.

Qhov chaw txheeb ze rau chaw nres tsheb sib nrug thiab tsav tsheb

Qhov twg lub thais nyob rau ntawm lub strip ntev cuam tshuam li cas nws cuam tshuam nrog pilots, lifters, thiab feed system. Ib txoj hauv kev yooj yim muab qhov chaw nres tsheb - txiav qhov chaw nres tsheb ib lossis ob ntawm qhov kev loj hlob zuj zus, yog li txhua qhov chaw nres tsheb tom ntej tau txais txiaj ntsig los ntawm kev txwv pub noj thiab kho lub camber ntawm qhov chaw nres tsheb.

Kev sib raug zoo ntawm qhov chaw nres tsheb thiab qhov chaw tsav tsheb yog ua ntu zus, tsis yog rov ua dua. Cov kws tsav dav hlau feem ntau koom nrog lub sawb ntawm qhov chaw nres tsheb ob lossis peb, tom qab lub thais tau txwv tag nrho cov khoom noj ntau dhau. Raws li MetalForming Magazine cov ntsiab lus, cov yob pub yuav tsum tso cov kab xev ua ntej tus kws tsav dav hlau nrhiav txoj kab uas hla nkag mus rau hauv qhov pilot qhov. Lub bypass notch muab lub ntxhib nres uas tau txais lub sawb nyob rau hauv pilot capture ntau yam, thiab tus tsav ces muab qhov kawg precision sau npe, feem ntau kho qhov kawg 0.05 mus rau 0.10 hli ntawm qhov chaw yuam kev.

Chaw nres tsheb sib nrug txiav txim siab deb npaum li cas lub hnab tshos lossis lub tab mus ncig ua ntej koom nrog qhov tseem ceeb thaiv lossis nres. Lub notch yuav tsum tau txiav kom nws trailing ntug aligns raws nraim ib lub suab deb ntawm qhov kev koom tes taw tes. Ib qho yuam kev ntawm no sib txuas hauv cov chaw nres tsheb. Yog hais tias qhov kev txiav txiav yog 0.02 hli tawm ntawm qhov tseeb, qhov yuam kev no nthuav tawm los ntawm txhua qhov chaw nres tsheb hauv qab, tsim kom muaj kev nce qib ntawm cov neeg tsav tsheb ib leeg yuav tsis raug tag nrho.

Lifter kev sib cuam tshuam ntxiv lwm qhov txwv. Thaum tuag nrog lub caij nplooj ntoos hlav- loaded lifter rails, lub strips tawm ntawm qhov tuag nto ntawm strokes kom pub kev nce qib. Ib qho zoo bypass tab projecting hauv qab lub sawb yuav tsum tshem tawm cov lifter rail ntawm qhov siab nqa tag nrho. Yog hais tias lub tab ntes tau, lub sawb tsis tuaj yeem nce mus, thiab tom ntej no stroke ua ob - ntaus. Rau qhov tsis zoo, qhov thaiv qhov tseem ceeb yuav tsum tau thim rov qab hauv qab lub dav hlau dav hlau ua ntej lifters tsa lub sawb, los yog cov phab ntsa ntswj ntes cov ntug thaiv thiab txiav cov nti thib ob rau hauv lub hnab ntim khoom.

Thaum siv ob qho tib si tsav thiab bypass notches yog siv ua ke, lub cuab tam thiab tuag tsim yuav tsum xyuas kom meej tus tsav tsis sib ntaus sib tua lub thais. Yog hais tias lub notch ntes lub sawb 0.05 hli luv ntawm qhov tseeb txoj hauj lwm thiab tus tsav ces drags nws mus rau pem hauv ntej, cov phab ntsa thais muaj kev nyuaj siab shear tiv thaiv qhov tseem ceeb thaiv ntawm txhua txhua stroke. Nyob rau tib lub sijhawm, qhov rov ua dua qhov kev qaug zog ua rau qhov kev txiav ntug. Qhov kev daws teeb meem yog qhov loj me me kom nws nres lub sawb me ntsis dhau ntawm lub qhov rais tsav tsheb, cia tus tsav rub lub sawb rov qab mus rau qhov kawg ntawm txoj hauj lwm es tsis yog thawb nws mus tom ntej.

Cov Khoom Khoom Uas Tsav Bypass Notch Tsim Kev Txiav Txim Siab

Lub bypass notch tsis yog ib tug geometric feature. Nws yog ib qho kev sib txuas ntawm cov khoom siv rov qab los ntawm kev thauj khoom, kev ntxhov siab, thiab kev hloov pauv txhua zaus thaum lub sawb ntes tawm tsam qhov tseem ceeb thaiv lossis nres. Yuav ua li cas qhov interface ua tau yog nyob ntawm seb lub sawb yog ua los ntawm. Ob cov ntaub ntawv uas zoo tib yam thickness thiab sawb dav tuaj yeem thov cov qauv sib txawv raws li lawv lub zog tawm los, kev coj tus cwj pwm tawv, thiab ductility.

Cov khoom siv li cas cuam tshuam rau kev ua haujlwm tsis zoo

Pib nrog yield zog. Engineered stampings tshwm sim los ntawm cov yas deformation tshwm sim los ntawm kev tsim rog dhau ntawm cov khoom siv lub zog, raws liMetalForming Magazinepiav qhia. Tib txoj cai tswj hwm kev sib koom ua ke. Thaum ib lub sawb tiv tauj ib qho tseem ceeb ntawm kev ceev, cov phab ntsa ntawm phab ntsa muaj kev sib zog ua kom muaj zog. Cov ntaub ntawv uas muaj zog dua yield zog tiv thaiv deformation ntawm qhov chaw tiv tauj, tswj kev nqis tes ua geometry dhau kev ua haujlwm ntev dua. Softer alloys zoo li annealed tooj liab los yog txhuas deform zuj zus, nrog rau phab ntsa nceb me ntsis ntawm txhua tus mob stroke kom txog thaum kev sib koom ua ke qhov tob ploj.

Lub zog tawm los ntawm steel sib txawv heev nyob rau hauv cov qib. Cov hlau me me ntawm 250 MPa coj txawv txawv ntawm qhov kev sib koom ua ke ntau dua li dual -theem steel ntawm 600 MPa. Siab dua - cov ntaub ntawv muaj zog tuav cov npoo npoo zoo dua tab sis tseem xa cov kev cuam tshuam ntau dua rau hauv qhov tseem ceeb thaiv, ua kom nrawm hnav ntawm cov khoom siv tuag ntau dua li cov sawb. Koj yog qhov tseem ceeb xaiv qhov chaw hnav tshwm sim: ntawm cov khoom siv hloov pauv tau los yog ntawm cov khoom siv tuag uas yuav tsum tau saib xyuas lub sijhawm rau kev pabcuam.

Lub elastic modulus ntawm cov khoom siv sawb txiav txim siab npaum li cas lub caij nplooj ntoos hlav rov qab cov kev paub tom qab txiav ua haujlwm. Cov ntaub ntawv uas muaj siab elastic modulus, zoo li cov hlau ntawm kwv yees li 200 GPa, lub caij nplooj ntoos hlav rov qab tsawg dua tom qab qhov kev txiav txim siab tawm, tawm hauv lub hnab tshos los ze zog rau nws cov geometry. Aluminium, nrog ib qho elastic modulus nyob ib ncig ntawm 70 GPa, tej zaum yuav zoo li nws yuav tsum rov qab los tsawg dua vim qhov qis qis, tab sis nws cov txiaj ntsig qis qis qis txhais tau tias nws nkag mus rau hauv cov yas deformation ua ntej, ua rau muaj qhov sib txawv ntawm elastic rov qab thiab teeb tsa mus tas li. Cov txiaj ntsig tau zoo yog tias qhov ntsuas phoo geometry yuav tsum tau them nyiaj sib txawv rau txhua tsev neeg cov khoom kom ua tiav tib qhov kawg qhov kawg.

Kev ua kom tawv tawv thiab ua haujlwm tawv tawv qhia lub sijhawm- nyob ntawm qhov sib txawv uas cov khoom zoo li qub tsis tuaj yeem ntes tau. Txhua lub sij hawm lub sawb hu rau qhov tseem ceeb thaiv, cov phab ntsa tsis muaj kev paub txog cov yas deformation hauv zos. Qhov kev deformation no ntxiv dag zog rau cov khoom ntawm thaj chaw tiv tauj. Tshaj li ntau txhiab lub voj voog, qhov ntswj ntug ua rau nyuaj thiab nkig ntau dua li cov khoom nqa khoom nyob ib puag ncig. Rau cov pa siab -lub zog qis- alloy steels, qhov kev ntxiv dag zog no tuaj yeem ncav cuag 20 feem pua ​​​​siab dua li - tau txais qhov xwm txheej. Rau qib siab siab - qib zog zoo li dual-theem steels, cov kev suav ntxhib qhia tau tias txawm tias ob peb feem pua ​​​​ntawm cov kab mob tuaj yeem ua rau muaj zog hauv zos los ntawm 50 feem pua ​​​​piv rau cov pav ca -cov ntaub ntawv.

Qhov ntawd localized hardening nws thiaj li ua rau tawg. Lub ntug ntug, tam sim no nkig los ntawm kev ua hauj lwm hardening, tawg nyob rau hauv lub tom ntej no tej yam load es tsis deforming. Cov chips me me tawg dawb, paug qhov tuag thiab degrading kev koom tes zoo. Cov ntaub ntawv uas muaj qhov tseem ceeb elongation siab, siab dua 30 feem pua ​​​​rau cov hlau me me, zam ntau lub voj voog ua ntej mus txog qhov tsis ua hauj lwm vim tias lawv tuaj yeem nqus rov qab deformation yam tsis tas ua rau lawv cov ductility. Tsawg- cov ntaub ntawv elongation zoo li lub caij nplooj ntoos hlav steels lossis cov qib stainless hlau hnyav ncav cuag qhov pib tawg sai dua, xav tau ntau qhov chaw nres tsheb hloov chaw lossis hloov mus rau qhov zoo thais tsim uas faib cov khoom noj khoom noj hauv cheeb tsam loj dua.

Cov qauv tsim yuav tsum suav rau cov khoom siv straining - kev coj cwj pwm hnyav dhau qhov kev tsim tawm tag nrho, tsis yog nws li - tau txais cov khoom siv kho tshuab, vim tias qhov chaw sib koom ua ke muaj zog thiab embrittles zuj zus nrog txhua lub voj voog pub.

Thickness thiab Sawb Dav Kho

Cov khoom thickness ncaj qha txiav txim siab yam tsawg kawg nkaus kev sib koom tes qhov tob. Ib qho tseem ceeb thaiv yuav tsum tau ua rau hauv lub hnab tshos tob tob kom tsis txhob muaj cov kab nrib pleb los ntawm nws thaum pub mis. Rau cov ntaub ntawv nyias hauv qab 0.5 hli, qhov no txhais tau hais tias qhov tseem ceeb thaiv qhov siab txheeb ze rau strip thickness yog qhov tseem ceeb. ntiav heev, thiab lub strip flexes hla lub block. Sib sib zog nqus heev, thiab lub thaiv tiv thaiv hauv qab ntawm lub hnab tshos thaib, tsim kom muaj qhov kev txiav txim siab thib ob uas ua rau ob qho tib si puas.

Cov ntaub ntawv tuab dua, siab dua 2.0 hli, ua kom muaj zog ntau dua thaum lub sijhawm pub khoom noj. Lub zog kinetic lub notch yuav tsum nqus ntawm txhua qhov stroke scale nrog ob qho tib si loj thiab tshaj tawm. Ib tug 2.5 hli sawb ntawm nruab nrab pub ceev hits tus yuam sij thaiv nrog considerably ntau zog tshaj ib tug 0.8 hli sawb ntawm tib ceev. Cov ntawv sib sib zog nqus nrog cov cheeb tsam loj dua faib cov quab yuam, tab sis kev txiav tob dua kuj tshem tawm cov khoom nqa khoom ntau dua.

Sawb dav teeb lub qab nthab ntawm qhov tob npaum li cas qhov tsis zoo notch tuaj yeem mus tau zoo. Raws licab kuj strip tsim qauvdictate, tus cab kuj yuav tsum nyob twj ywm muaj zog txaus los tiv thaiv dabtsi yog khoov thaum pub mis. Tshem tawm 25 feem pua ​​​​ntawm txhua ntug ntawm 40 mm strip tawm 20 mm ntawm cov cab kuj hla ntu. Ntawm lub siab - lub zog steel, uas yuav tsim nyog. Nyob rau hauv ib tug mos aluminium alloy nrog ib tug -thib peb lub zog tawm los, tib geometry buckles nyob rau hauv pub quab yuam. Koj yuav tsum tau ntsuas qhov tob tob inversely nrog cov khoom siv zog: softer alloys tau txais qhov tob tob thiab vam khom ntau dua ntawm cov ntsiab lus tseem ceeb thaiv qhov geometry dua li kev sib koom tes tob.

High- steels muaj zog nthuav qhia lawv tus kheej hloov kho. Cov tub rog yuav tsum tau txiav ib qho kev txiav txim siab los ntawm cov qib no xav tau cov punch hnyav dua, cov seem tuag muaj zog dua, thiab kev tshem tawm nruj dua los tswj cov lus tshaj tawm burr cov ntaub ntawv tsim tawm. Copper alloys thiab aluminium txiav huv si nrog tsawg zog tab sis deform ntawm qhov kev koom tes. Txhua tsev neeg cov ntaub ntawv thawb tus qauv tsim nyob rau hauv ib qho kev taw qhia sib txawv, thiab tib txoj cai thoob ntiaj teb yog tias tsis muaj ib qho geometry ua haujlwm thoob plaws tag nrho lawv yam tsis muaj kev hloov kho.

Cov khoom siv no -kev coj cwj pwm tsis yog cuam tshuam rau kev tsim thawj zaug xwb. Lawv kwv yees yuav ua li cas ib tug notch yuav degrade nyob rau hauv lub sij hawm, uas tsis ua hauj lwm hom yuav tshwm sim ua ntej, thiab yuav tsum tau saib xyuas ntau npaum li cas. Qhov kev kwv yees kev sib raug zoo ntawm cov khoom siv thiab cov qauv tsis ua haujlwm yog raws nraim li cas cais cov kev saib xyuas tsis zoo los ntawm kev daws teeb meem tom qab tuag tau tsim cov khoom seem.

Failure Modes thiab Troubleshooting Bypass Notch teeb meem

Ib tug bypass notch uas ua hauj lwm zoo kawg nkaus ntawm stroke ib puas txhiab yuav ua tsis tiav los ntawm stroke tsib puas txhiab. Lub degradation yog maj mam, uas tau tsav los ntawm tib yam khoom coj cwj pwm uas tau tham saum toj no: hauv zos strain hardening ntawm qhov chaw sib koom ua ke, nce burr tsub zuj zuj, thiab cyclic cuam tshuam quab yuam uas qaug zog ob leeg strip thiab tuag Cheebtsam. Paub txog qhov ua tsis tiav thiab vim li cas nws ua tsis tiav ua ntej cov khoom seem pib sib cais cais cov khw uas tswj hwm lub sijhawm los ntawm cov neeg daig hauv kev tua hluav taws.

Hom Failure Hom rau Txhua Qhov Ncauj Hom

Tsis zoo thiab zoo bypass notches poob hauv kev sib txawv vim lawv cov tshuab sib txawv. Ib qho tsis zoo thaib cia siab rau ntawm lub hnab txiav txiav thiab qhov projecting tseem ceeb thaiv. Ib qho txiaj ntsig zoo tso siab rau ntawm lub tab tsim thiab nres nres. Txhua lub geometry qhia txog nws tus kheej hnav cov qauv, thiab txhua tus xav tau kev kuaj mob sib txawv.

Rau qhov tsis zoo, qhov cuam tshuam tsis zoo tshaj plaws yog slug rub. Cov sliver me me txiav los ntawm lub strip ntug adheres rau lub ntsej muag lub ntsej muag thaum tshem tawm thiab tau nqa rov qab mus rau hauv qhov tuag. Cov slug ntawd nws thiaj li tso rau hauv lub hnab tshos hauv qab ntawm qhov chaw nres tsheb hauv qab, ib nrab lossis tag nrho thaiv qhov tseem ceeb ntawm kev nkag mus. Lub sawb hla dhau yam tsis tau ntes, thiab tom ntej no ntaus av nyob rau hauv qhov chaw tsis ncaj ncees lawm.Progressive tuag teeb meem cov ntaub ntawvlees paub tias lub tshuab nqus tsev cuam tshuam ntawm cov punch thiab slug, ua ke nrog kev tshem tawm tsis txaus lossis hnav lub tshuab ejection, yog thawj tsav tsheb. Lub caij nplooj ntoos hlav ejectors, cua tshuab-tawm, thiab cov slug clearance tsim kom zoo txo ​​qhov kev pheej hmoo, tab sis hnav punches nrog degraded nto tiav tseem yog lub hauv paus pib.

Burr buildup yog qhov qeeb - hlawv tsis ua hauj lwm hom. Txhua tus mob stroke ua rau me me burr ntawm qhov tuag sab ntawm qhov txiav txiav. Qhov burr tej yaam num rau hauv lub hnab tshos, zoo txo ​​qhov kev ua haujlwm qhov tob ntawm ob peb microns ib txhiab strokes. Thaum kawg tus yuam sij thaiv tsis tuaj yeem zaum tag nrho, thiab qhov nres yuav tsis tuaj yeem ntseeg tau. Cov ntaub ntawv uas tau ua haujlwm nyuaj thaum ua haujlwm ua ntej, lossis siab - qib siab tshaj 500 MPa tawm los ntawm kev ntxhov siab, tsim cov burrs siab dua thiab ua kom qhov kev puas tsuaj no.

Notch ntug cracking tshwm nyob rau ntev ntau lawm khiav, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv uas muaj strain hardening. Kev cuam tshuam rov qab ntawm qhov tseem ceeb thaiv tawm tsam phab ntsa tsis zoo zuj zus zuj zus thiab ua rau thaj tsam ntawd. Thaum lub ductility hauv zos tas lawm, micro- tawg pib thiab nthuav tawm. Chips tawg dawb los ntawm ntug ntug, kis kab mob tuag thiab ua kom tsis zoo rau kev koom tes ntxiv.

Rau cov txiaj ntsig zoo, qhov tseem ceeb tsis ua haujlwm yog tab khoov lossis shearing. Thaum lub yielding quab yuam siv los ntawm lub sawb lub zog tshaj lub tab qhov tsis kam, tab deforms rau pem hauv ntej es tsis txhob nres lub strip. Qhov no tshwm sim thaum pub ceev yog siab dhau ntawm cov khoom thickness, los yog thaum lub lance cag tsim qaug zog tawg uas tsis muaj zog tab qhov txuas taw tes. Thaum ib lub tab khoov txawm me ntsis, nws tsis tiv thaiv qhov thaiv ntawm lub kaum sab xis, thiab txhua qhov mob stroke txuas ntxiv ua rau deformation.

Tab cuam tshuam nrog lifters yog kev teeb tsa - cuam tshuam tsis ua haujlwm. Yog hais tias lifter rail qhov siab tsis ua hauj lwm nrog tab projection qhov tob, tab catches ntawm lub tsheb ciav hlau thaum lub sij hawm sawb elevation. Lub sawb tsis tuaj yeem ua tau yooj yim, thiab cov khoom noj khoom haus tom ntej no buckles cov khoom nruab nrab ntawm lub feeder thiab qhov cuam tshuam. Progressive tab deformation los ntawm kev cuam tshuam rov qab los kuj hloov lub sijhawm sib koom ua ke: raws li tab nceb ntawm nws lub ntsej muag tiv tauj, txoj haujlwm nres tau zoo hloov mus rau pem hauv ntej los ntawm tus nqi deformation, qhia txog me me tab sis kev sau npe yuam kev.

Troubleshooting Strip Misfeeds thiab Buckling

Cov neeg ua haujlwm tuag tsis tshua pom qhov ntsuas nws tus kheej ua tsis tiav. Qhov lawv pom yog qhov tshwm sim hauv qab: qhov chaw uas ntsuas qhov tsis sib xws, strips uas buckle ntawm chaw nres tsheb, thiab xuas nrig ntaus uas hnav ua ntej lub sijhawm. Txuas cov tsos mob rov qab mus rau qhov ntsuas qhov system yog qhov nyuaj rau kev kuaj mob.

Qhov tsis sib xws ntawm qhov ntev, tshwj xeeb tshaj yog thaum qhov ntev sib txawv los ntawm qhov me me thoob plaws ib qho kev khiav haujlwm, feem ntau qhia tias kev tso npe tawm los ntawm kev sib koom ua ke tsis zoo. Qhov tseem ceeb thaiv tsis yog tag nrho ntes cov sawb, yog li txhua tus ntaus av me ntsis rau pem hauv ntej los yog luv ntawm nominal txoj hauj lwm. Kev ntsuas lub suab ntawm lub suab ntawm qhov kev sib koom ua ke, tsis yog tsuas yog tso siab rau ib feem ntawm qhov ntev, cais seb qhov kev sau npe yuam kev los ntawm qhov ntsuas lossis ntawm qhov chaw nres tsheb hauv qab.
