• Kev them nyiaj Springback yog qhov nyuaj rau kev tswj hwm kev khiav mus ntev: nyiam qhov tsis zoo rau kev tshem tawm zoo ib yam

Cov txheej txheem no sib cuam tshuam. Ib qho khoom siv nyias nyias hauv 12- chaw nres tsheb tuag nrog cov nqa nqa nqa tau xav tau cov txiaj ntsig zoo. Lub tuab stainless hlau dawb paug nyob rau hauv 4- chaw nres tsheb tuag nrog dav ntug cov ntsiab lus kom meej meej rau qhov tsis zoo. Cov ntawv thov tiag tiag hauv ntiaj teb feem ntau poob rau qhov chaw ntawm qhov kev kub ntxhov no, xav kom tus tsim qauv ntsuas kev lag luam tawm thiab qee zaum sib xyaw ob hom hauv ib qho kev teeb tsa ib leeg.

Xaiv txoj cai bypass notch hom xauv hauv qhov kev taw qhia tsim. Qhov kev sib tw tom ntej no yog qhov ntsuas qhov ntsuas kom raug, vim tias qhov qis qis ua rau muaj kev cuam tshuam thiab qhov loj me me ua rau lub zog tsis muaj txiaj ntsig ntxiv.

Yuav ua li cas Bypass Notch Dimensions raug txiav txim

Kev xaiv ntawm qhov zoo thiab qhov tsis zoo bypass notch teeb tsa tus qauv tsim. Sizing qhov notch kom raug txiav txim seb nws puas ua haujlwm hauv kev tsim khoom. Ib tug undersized notch ntes ntawm cov khoom tuag thiab ua rau misfeeds. Ib qho loj me me pov tseg cov khoom nqa khoom lossis qhia txog qhov tsis tsim nyog kev ntxhov siab. Qhov chaw qab zib yog nyob rau hauv kev nkag siab txog dab tsi tsav cov qhov ntev ntawm qhov kev xav ntawm engineering.

Xam xam Notch Qhov tob thiab dav kom txaus Clearance

Lub hom phiaj tseem ceeb ntawm ib qho bypass notch yog clearance. Lub sawb yuav tsum dhau cov khoom ruaj ruaj ruaj khov thaum lub sij hawm indexing, tsis muaj kev sib cuag thiab tsis rub. Yog li lub bypass notch qhov tob xam nyob rau hauv ib tug zuj zus tuag pib nrog ib lo lus nug: dab tsi yog lub strip sim kom meej?

Peb qhov kev tuag feem ntau tsim kom muaj qhov tsawg kawg nkaus tshem tawm:

• Kev tsim cov hlau:Cov no protrude saum lub ntsej muag tuag rau cov khoom siv ntawm cov chaw ua haujlwm dhau los. Qhov siab ntawm txoj kev hlau saum toj no lub dav hlau mus txawv tebchaws txhais qhov tsawg kawg nkaus thais qhov tob uas xav tau rau lub sawb mus rau qhov ntsuas yav dhau los yam tsis tau ntes.
• Lifter Travel:Caij nplooj ntoos hlav-loaded lifters tsa lub strip saum toj tuag lub ntsej muag ntawm nias strokes kom tso cai indexing. Lub lifter stroke txiav txim siab npaum li cas lub sawb caij thaum nce qib. Yog hais tias ib tug bypass notch yuav tsum tau tshem tawm ib feem thaum lub sawb nyob rau hauv nws lifted txoj hauj lwm, lub clearance xam yuav tsum suav rau ob qho tib si qhov siab thiab lub sawb elevation ntawm lub point.
• Pilot txoj kab uas hla:Cov kws tsav dav hlau nrhiav lub sawb kom meej ntawm txhua qhov chaw nres tsheb. Lub sawb yuav tsum tau ua ntej tus pins yav dhau los yam tsis muaj tus neeg nqa khoom ntug lossis ib qho kev tsim ua yav dhau los snagging ntawm tus pin lub cev. Notch dav yuav tsum tshaj tus tsav txoj kab uas hla ntxiv rau ib tug clearance margin ntawm txhua sab.

Yuav ua li cas dimension bypass notches nyob rau hauv stamping feem ntau ua raws li ib tug ncaj txoj cai: qhia notch qhov tob raws li ib tug ntau yam ntawm cov ntaub ntawv thickness. Rau qhov tsis zoo ntawm kev tshem tawm cov hlau, qhov pib pib yog 1.5 txog 2.5 npaug ntawm cov khoom tuab, nyob ntawm qhov siab ntawm cov hlau. Rau cov txiaj ntsig zoo, qhov sib sib zog nqus qhov tob feem ntau tau teev tseg ntawm 1.0 mus rau 1.5 npaug ntawm cov khoom tuab vim tias qhov sib sib zog nqus npib yuav ua rau tawg lossis ntau lub caij nplooj ntoo hlav hauv ntau cov ntaub ntawv.

Notch dav ua raws li cov laj thawj zoo sib xws. Nws yuav tsum ncua tag nrho qhov dav ntawm txhua yam kev tuag tivthaiv lub sawb yuav tsum tau hla, ntxiv rau kev tshem tawm ntawm txhua sab. Ib qho kev tsis sib xws yog 0.5 mus rau 1.0 mm rau ib sab rau cov khoom hauv qab 10 mm dav, scaling li proportionally rau loj obstructions. Lub hom phiaj yog ib qho thais uas muab kev tso cai pub dawb yam tsis tau tshem tawm cov khoom thauj ntau dua li qhov tsim nyog.

Clearance Tolerances thiab Material Springback Effects

Tau txais qhov pib qhov ntev yog tsuas yog ib nrab ntawm kev sib tw. Kev tuav tswj kom txaus bypass notch clearance kam rau ua nyob rau hauv ib tug stamping tuag ntau txhiab los yog lab lub voj voog qhia ntxiv hloov pauv uas tus tsim yuav tsum xav txog.

Rau qhov zoo bypass notches, cov khoom springback yog thawj qhov kev txhawj xeeb. Thaum lub npib nyiaj npib thim rov qab, lub tab hloov pauv ib nrab rov qab mus rau lub dav hlau sawb. Qhov kev tshem tawm tau zoo tom qab springback yog ib txwm tsawg dua qhov punch qhov tob. Tsawg npaum li cas nyob ntawm cov khoom siv, thickness, thiab cov kev coj ntawm cov nplej. Cov khoom siv qis- carbon steels tuaj yeem rov qab 10 mus rau 15 feem pua ​​​​ntawm cov coined qhov tob. Siab dua - cov ntaub ntawv muaj zog lossis ua haujlwm - cov chaw tawv tawv tuaj yeem rov qab 25 feem pua ​​lossis ntau dua.

Qhov no txhais tau tias koj cov ntaub ntawv springback bypass notch tsim yuav tsum overbuild tus thawj npib qhov tob kom tsaws ntawm lub hom phiaj clearance tom qab elastic rov qab. Yog tias koj xav tau 1.0 hli ntawm kev ua haujlwm tshem tawm thiab cia siab tias 20 feem pua ​​​​ntawm lub caij nplooj ntoo hlav, lub npib nyiaj npib yuav tsum hloov cov khoom mus rau kwv yees li 1.25 hli. Tshaj qhov kev ncua sij hawm ntau lawm, rov qab strip flexing ntawm thaj tsam coined tuaj yeem ntxiv cov deformation, maj mam txo qhov kev tshem tawm. Qhov kev ua kom zoo zuj zus no yog vim li cas qhov kev tsim qauv zoo tau txais txiaj ntsig los ntawm kev saib xyuas thawj zaug overbuild margins.

Tsis zoo bypass notches ntsib ib tug sib txawv teeb meem ntawm kam rau ua. Txij li thaum cov khoom raug txiav tawm tag nrho, springback tsis cuam tshuam rau qhov tob tob. Qhov tob tob yog ruaj khov thaum lub slug sib cais. Txawm li cas los xij, xuas nrig ntaus-rau- tuag tshem tawm ncaj qha cuam tshuam rau kev txiav ntug zoo thiab burr kev taw qhia. Txuj kev xyaum rau kev ua haujlwm xuas nrig ntaus pom zooclearance nyob ib ncig ntawm 10 feem pua ​​ntawm cov khoom thickness rau me me hlau, scaling rau kwv yees li 15 feem pua ​​​​rau stainless hlau. nruj heev lub clearance tsim ntau shearing quab yuam thiab accelerates punch hnav. Kev xoob dhau lawm ua rau cov burrs loj dua thiab rougher ntug profiles ntawm cov phab ntsa.

Burr kev taw qhia tseem ceeb vim hais tias ib qho kev nce siab -fab burr ntawm qhov tsis zoo bypass notch tuaj yeem txo qhov kev tshem tawm zoo los ntawm qhov siab burr, uas yuav ua rau lub sawb mus rau ntawm qhov feem ntau nws tau tsim los kom meej. Kev tswj cov burr kev taw qhia los ntawm cov chaw tshem tawm kom raug thiab xuas nrig ntaus yog ib feem ntawm kev tuav lub sijhawm ntev - lub sijhawm ua haujlwm.

Hauv qab - qhov ntev bypass notches ua rau strip cuam tshuam, misfeeds, thiab kev puas tsuaj loj zuj zus. Tshaj - qhov ntsuas qhov ntsuas qhov ntsuas cuam tshuam cov cab cab lub zog tsis muaj kev pab cuam ntxiv. Qhov tseeb dimension nyob ntawm qhov tsawg kawg nkaus clearance uas guarantees dawb strip pass thiab ib tug tswj kev nyab xeeb margin, tsis muaj dab tsi ntxiv.

Kub ntxiv lwm txheej. Thaum lub sij hawm siab - ntau lawm, cov khoom tuag ua kom sov thiab nthuav dav. Ib tug bypass notch dimensioned ntawm ambient kub tej zaum yuav poob ib feem ntawm nws clearance li tsim steels los yog pilots thermally nthuav mus rau hauv txoj kev mus. Rau cov tuag khiav saum 200 strokes ib feeb, factoring nyob rau hauv ib tug thermal expansion buffer ntawm 0.02 mus rau 0.05 hli tiv thaiv marginal cuam tshuam ntawm kev khiav hauj lwm kub.

Tag nrho cov kev txiav txim siab me me no ua rau cov duab geometry ua ntej ib feem yog stamped. Tab sis lub notch tsis muaj nyob rau hauv kev sib cais ntawm lub sawb. Qhov twg koj tso nws txheeb ze rau qhov kev tsav tsheb, cov kab noj, thiab cov cheeb tsam tsim kev txiav txim siab seb cov kev ntsuas ua tib zoo ntsuas qhov ntev npaum li cas ua tau zoo ib yam ntawm cov kab nrib pleb thoob plaws hauv qhov tuag.

Bypass Notch Placement thiab Pilot Registration Interaction

Ib tug raug dimensioned bypass notch muab tso rau hauv qhov chaw tsis ncaj ncees lawm tsim teeb meem loj npaum li ib tug undersized. Lub sawb tsis muaj nyob ua ib daim ntaub dawb. Pilot qhov, pub siv zones, thiab tsim cov cheeb tsam tag nrho sib tw rau tib lub vaj tse nyob ntawm ntug nqa khoom. Qhov twg koj nrhiav txhua qhov kev txheeb ze rau cov yam ntxwv no txiav txim siab seb koj qhov kev ua tiav tuag strip layout muab kev sau npe zoo ib yam lossis sib sau ua yuam kev hauv chaw nres tsheb.

Bypass Notch Placement txheeb ze rau Pilot Holes

Pilots yog tus txha nraub qaum ntawm txhua qhov kev tuag. Raws li tau piav qhia nyob rau hauv kev xyaum tsim kev tuag, cov neeg tsav dav hlau nkag mus rau hauv qhov punched nyob rau hauv cov chaw thaum ntxov thiab yuam kom raug strip txoj hauj lwm ua ntej cov cuab yeej tsim kev sib cuag. Qhov kev kho ntawd yog nyob ntawm tus tsav lub qhov tswj nws qhov qub punched geometry: puag ncig, huv si, thiab dimensionally ruaj khov.

Muab ib qho bypass thais ze ze rau lub qhov pilot, thiab koj cuam tshuam qhov geometry. Nov yog vim li cas. Ib qho tsis zoo bypass notch shear cov khoom los ntawm cov cab kuj ntug, tsim cov kev ntxhov siab hauv cheeb tsam redistribution nyob rau hauv ib puag ncig cheeb tsam. Yog hais tias qhov kev ntxhov siab ntawd mus txog qhov kev tsav tsheb, nws tuaj yeem ua rau muaj kev hloov pauv hloov maj mam, rub lub qhov me ntsis tawm ntawm ib puag ncig lossis hloov nws qhov chaw zoo. Tus tsav tseem nkag mus rau hauv lub qhov, tab sis kev kho nws siv yog tam sim no referencing ib tug distorted datum. Qhov kev tso npe tsav tsheb yuam kev los ntawm kev cuam tshuam los ntawm kev cuam tshuam tuaj yeem tsuas yog 0.02 txog 0.05 hli ntawm qhov chaw nres tsheb, tab sis nws cascades thiab cov tebchaw los ntawm txhua qhov kev khiav dej num.

Qhov zoo bypass notches tsim muaj kev pheej hmoo zoo sib xws los ntawm kev sib txawv.

Cov kab ke no kho cov kev siv cov khoom siv raws li qhov tseem ceeb hauv qab es tsis yog qhov pib txwv. Kev sau npe raug thiab kev cia siab rau kev pub noj yog thawj zaug vim tias tsis muaj nyiaj khaws cia ua rau muaj kev tuag uas misfeeds. Thaum cov kev xav tau raug kaw lawm, qhov kev tsim kho kom zoo yog tsom rau kev txo qis hauv qhov chaw tsim khoom seem.

Kev txiav txim siab qhov chaw tso cai rau qhov chaw qhov chaw nyob ntawm qhov chaw. Tab sis lub sawb tsis muaj nyob rau hauv kev sib cais ib yam. Nws nqa cov khoom thauj thoob plaws nws qhov ntev, thiab txhua qhov kev txiav txim siab, txawm tias qhov tsis zoo lossis qhov zoo, hloov pauv li cas cov khoom xa tawm los ntawm tus nqa khoom los ntawm chaw nres tsheb mus rau chaw nres tsheb.

Carrier Strip Strength thiab Bypass Notch Design Considerations

Ib txoj hlua cab kuj tsis tsuas yog tuav cov khoom ua ke. Nws xa cov khoom siv dag zog thoob plaws txhua qhov chaw nres tsheb, tiv thaiv deflection nyob rau hauv nws tus kheej qhov hnyav thiab qhov hnyav ntawm ib feem ntawm qhov tsim, thiab tswj qhov kev ruaj ntseg nyob rau hauv tag nrho cov xovxwm stroke voj voog. Txhua qhov bypass thais koj qhia txog kev hloov pauv uas thauj - nqa daim duab. Cov lus nug tsis yog seb qhov thais puas cuam tshuam rau kev ncaj ncees ntawm tus neeg nqa khoom, tab sis ntau npaum li cas, thiab seb qhov kev cuam tshuam loj npaum li cas nyob hauv qhov kev txwv.

Txhim kho cov neeg nqa khoom muaj zog los ntawm ntau qhov chaw nres tsheb

Xav txog qhov 14-chaw nres tsheb nce toj tuag nrog qhov tsis zoo bypass notches ntawm chaw nres tsheb 3, 5, 7, 9, thiab 11. Txhua qhov chaw nres tsheb tshem tawm cov duab plaub ntawm ntug nqa khoom. Ntawm chaw nres tsheb 3, tus neeg nqa khoom hla-section nqis me ntsis. Los ntawm qhov chaw nres tsheb 11, tsib qhov kev tshem tawm cov khoom sib cais tau txo qhov dav ntawm qhov hnyav ntawm qhov sib txawv ntawm cov sawb. Cov neeg nqa khoom uas nkag mus rau hauv chaw nres tsheb 12 yog ntsuas tsis muaj zog tshaj qhov uas nkag mus hauv chaw nres tsheb 1.

Qhov no cumulative cab kuj tsis muaj zog los ntawm qhov tsis zoo bypass notches tsim ib tug compounding teeb meem. Carrier lub zog cov hauv paus ntsiab lus qhia tau hais tias lub sawb yuav tsum tiv thaiv dabtsi yog khoov quab yuam proportional rau tus naj npawb ntawm kev loj hlob multiplied los ntawm ib feem qhov hnyav. Yog tias tus neeg nqa khoom hla- ntu txo qis ntawm ntau lub ntsiab lus, ntu tsis muaj zog tswj hwm tag nrho cov sawb rigidity. Ib qho hauv qab -tsim thais nyob rau hauv ib txoj hlua ntawm tsib tuaj yeem dhau los ua qhov tsis ua haujlwm uas buckles lub sawb lossis ua rau nws poob ntawm cov lifters.

Cov neeg tsim khoom tuag yuav tsum sib npaug qhov kev xav tau tshem tawm tawm tsam qhov kev muaj tiag ntawm cov qauv no. Cov kev coj ua muaj xws li:

• Staggering qhov tsis zoo qhov chaw nruab nrab ntawm sab laug thiab sab xis nqa cov npoo yog li ob sab tsis muaj zog ntawm tib lub chaw nres tsheb
• Txo tus kheej qhov dav dav mus rau qhov tsawg kawg nkaus uas yuav tsum tau tshem tawm es tsis yog siv cov ntawv loj loj thoob plaws
• Ntxiv stiffening tav los yog hlaws dai rau cov cab kuj nruab nrab ntawm qhov chaw ntswj kom rov qab tau qee qhov ploj rigidity
• Hloov mus rau qhov zoo notches ntawm downstream chaw nres tsheb uas cumulative cov ntaub ntawv poob mus txog tus cab kuj lub zog txwv

Qhov zoo bypass notches khaws cov neeg nqa khoom hla -section nkaus. Cov khoom siv nyob twj ywm txuas, tswj qhov dav dav ntawm txhua qhov chaw nres tsheb. Qhov no yog lawv qhov zoo ntawm cov qauv hauv high-chaw nres tsheb- suav tuag. Txawm li cas los xij, lawv qhia txog qhov kev txhawj xeeb sib txawv: kev ntxhov siab ntau hauv cov cheeb tsam coined. Cov yas deformation uas tsim lub tab hloov chaw kuj ua haujlwm - hardens cov khoom nyob ib puag ncig thiab tsim ib cheeb tsam ntawm cov kev ntxhov siab seem. Raws li rov qab strip flexing raws li tus nqa nqa nqa thiab qis dua nyob rau hauv lub voj voog, cov kev ntxhov siab no tuaj yeem dhau los ua qhov chaw pib ua rau qaug zog tawg, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv nyuaj lossis tsawg dua.

Kev lag luam - tawm yog qhov tseeb. Cov ntawv tsis zoo txo ​​qis -section tab sis tso cov khoom seem hauv nws qhov qub. Cov txiaj ntsig zoo khaws cov ntoo khaub lig-section tab sis hloov pauv cov ntaub ntawv lub xeev ntawm txhua cheeb tsam coined. Tsis yog ob txoj hauv kev yog universally superior rau cov cab kuj strip zog bypass notch tsim. Qhov kev xaiv yog nyob ntawm seb koj daim ntawv thov tshwj xeeb puas nkag siab ntau dua rau kev hla -section poob lossis qaug zog loading ntawm kev ntxhov siab.

Cov khoom ntws thiab deformation qauv nyob ib ncig ntawm cov ntawv

Bypass notches tsis muaj nyob rau hauv kev sib cais ntawm tus cab kuj. Cov chaw nyob ib sab feem ntau ua cov haujlwm tsim xws li rub, khoov, lossis lances uas nyob ntawm cov khoom tswj tau ntws mus rau hauv cov kab noj hniav. Thaum ib tug bypass notch zaum ze ntawm lub active forming cheeb tsam, nws disrupts lub uniformity ntawm uas ntws.

Xav txog cov nplej ntws cuam tshuam ze ntawm bypass thais txiav. Thaum lub qhov tsis zoo yog xuas nrig ntaus los ntawm tus nqa khoom ntug, qhov kev txiav txiav txiav cov nplej ntawm qhov txiav ciam teb. Cov ntaub ntawv uas nyob ib sab ntawm ntug uas raug txiav tsis muaj kev txhawb nqa ntxiv lawm. Yog tias ib qho chaw tsim khoom tam sim ntawd downstream rub cov khoom mus rau qhov chaw tsis txaus ntseeg, cov ntug uas tsis muaj kev txhawb nqa tuaj yeem tsim kua muag, wrinkle, los yog tsim tsis sib xws vim tias txoj kev lis ntshav tau cuam tshuam. Cov khoom siv tsis muaj qhov twg los kos los ntawm qhov tsis muaj dab tsi, tsim kom muaj cov qauv asymmetric ntws uas pom tau tias tsis sib xws ntawm phab ntsa tuab lossis hauv cheeb tsam thinning hauv cov qauv tsim.

Qhov zoo bypass notches tsim ib qho txawv. Lub npib nyiaj ua haujlwm compresses cov khoom nyob rau hauv qhov chaw thaib, hauv zos txo cov tuab thiab qhia txog kev ntxhov siab nyob hauv - dav hlau. Cov ntaub ntawv ntws ncig bypass notches nyob rau hauv ib tug zuj zus tuag yog cuam tshuam vim hais tias lub coined cheeb tsam resists ntxiv deformation. Cov kev ua haujlwm sib txuas ua ke uas sim rub cov khoom siv los ntawm thaj tsam yav dhau los coined ntsib kev tiv thaiv ntau dua hauv cheeb tsam hauv cheeb tsam, uas tuaj yeem hloov pauv cov hlau ntws thiab tsim cov khoom sib txawv tsis sib xws hauv qhov ua tiav.

Cov teebmeem no dhau los ua qhov tseem ceeb hauv cov xwm txheej tshwj xeeb:

• Lub bypass notch ntug yog nyob rau hauv 5 mm ntawm ib tug active tsim ciam teb
• Kev ua haujlwm tsim muaj cov khoom kos lossis ncab uas rub mus rau qhov chaw thais
• Ib feem geometry yuav tsum muaj cov phab ntsa tuab hauv cov cheeb tsam uas nyob ib sab ntawm cov cab kuj
• Cov khoom yog nyias txaus (qis dua 0.8 hli) uas cov khoom lag luam cuam tshuam hauv cheeb tsam propagates ntxiv txheeb ze rau qhov ntev

Thaum cov kev mob no converge, lub bypass notch cuam tshuam qhov kawg qhov zoo txawm tias nws yeej tsis dhau los ua ib feem ntawm cov khoom tiav. Cov qauv kev ntxhov siab seem los ntawm ib qho txiaj ntsig zoo, lossis qhov tsis sib xws ntawm cov nplej tsis zoo los ntawm qhov tsis zoo txiav, txuas mus rau hauv cov khoom uas tom qab ua rau sab ntug lossis ze ntawm -ntug feature. Qhov chaw trimmed nyob ze rau tus cab kuj taw tes txuas nqa cov teebmeem rau hauv cov geometry tiav.

complex bypass notch configurations, tshwj xeeb tshaj yog nyob rau hauv multi-chaw nres tsheb loj zuj zus tuag nrog nruj kev txwv, thov ceev faj tsom xam ntawm cov kev sib tshuam. Cov kws tsim khoom ua haujlwm los ntawm kev sib tw ntawm kev ncaj ncees hauv kev tuag nrog ntau dua 8 lossis 10 chaw nres tsheb feem ntau yuav tsum sim simulate cov ntaub ntawv ntws thiab xyuas kom meej tias qhov kev cuam tshuam -kev cuam tshuam tsis tuaj yeem nthuav tawm mus rau hauv qhov chaw tseem ceeb. Rau kev tsim- cov ntawv siv hnyav uas hla qhov kev tso chaw hla kev cuam tshuam nrog kev ua haujlwm, nqa kev mus ncig, thiab lub zog thauj khoom ib txhij, cov cuab yeej tshwj xeeb kev txhawb nqa engineering tuaj yeem txo qhov iteration cycles.YICHEN kev cai stamping tuag daws teeb meemnyob rau hauv raws nraim cov chav kawm ntawm qhov teeb meem no, muab cov qauv tuag thiab cov khoom ntws kev txawj ntse rau kev vam meej tuag qhov twg bypass notch tsim cuam tshuam nrog cov cab kuj ncaj ncees ntawm txhua qhov chaw nres tsheb.

Kev sib cuam tshuam ntawm tus qauv tsim thiab kev coj tus cwj pwm yog ib qho kev txhawj xeeb txog qib -. Txhua qhov kev xaiv, los ntawm qhov ntsuas qhov ntsuas mus rau qhov tob, nkag mus rau hauv seb lub sawb puas muaj sia nyob tag nrho kev tuag tsis muaj degradation. Tab sis txawm zoo -tsim notches tuaj yeem tsim teeb meem ntau txhiab lub voj voog ntau lawm, thiab paub txog cov qauv tsis ua haujlwm thaum ntxov yog dab tsi cais cov txheej txheem ruaj khov los ntawm ib qho uas ua rau seem thiab poob qis.

Troubleshooting Bypass Notch Failure Modes nyob rau hauv ntau lawm

Lub bypass thais uas ua tau flawlessly thaum lub sij hawm sim tuaj yeem tsim teeb meem ntau txhiab lub voj voog mus rau hauv kev ua haujlwm ntau lawm. Hnav, thermal hloov, thiab cov khoom sib txawv qhia txog cov xwm txheej uas tus qauv tsim tsis tau xav txog. Paub txog yuav ua li cas cov kev ua tsis tiav no tshwm sim rau lawv tus kheej, thiab taug qab txhua tus tsos mob rov qab mus rau nws cov hauv paus hauv paus, yog dab tsi ua rau cov neeg tuag khiav mus los tsis yog zaum ntawm lub rooj ntev zaum.

Peb pawg tsis ua hauj lwm sib txawv suav nrog rau feem ntau ntawm cov teeb meem hla dhau kev tsim khoom: slug- cuam tshuam cov teeb meem hauv qhov tsis zoo, cuam tshuam -tsav misfeeds, thiab mechanical degradation ntawm zoo notch npib. Txhua pawg tsim cov tsos mob sib txawv, xav tau cov kev kuaj mob sib txawv, thiab teb rau cov kev kho sib txawv.

Slug Pulling thiab Burr Tsim nyob rau hauv Negative Bypass Notches

Txhua qhov tsis zoo bypass notch generates ib tug slug ntawm txhua tus xovxwm stroke. Nyob rau hauv ib txwm muaj xwm txheej, tus slug poob huv si los ntawm qhov tuag matrix thiab tawm mus rau hauv ib lub chute. Thaum lub slug sticks rau lub ntsej muag lub ntsej muag thaum lub sij hawm retraction es tsis txhob nyob rau hauv lub matrix, koj muaj ib tug slug rub tus mob, thiab cov kev tshwm sim nce ceev.

Ib tug rub tawm tuaj yeem rov- tso rau ntawm daim kab xev, lub ntsej muag tuag, lossis hauv qhov sib sau ua ke. Yog tias nws tsaws ntawm lub sawb thiab nqa mus rau qhov chaw nres tsheb tom ntej, ib qho slug tuaj yeem ua rau cov hlau tsis sib haum, cuam tshuam qhov chaw, lossis tawg punches hla txhua qhov chaw nres tsheb hauv qab. Raws lituag science tshawb fawbpiav qhia, qhov tshwm sim ntawm cov slug rub tuaj yeem ua rau muaj kev puas tsuaj vim tias ib qho slug nqa los ntawm kev tuag zuj zus tuaj yeem ua rau muaj kev puas tsuaj rau txhua qhov chaw hauv lub cuab yeej.

Dab tsi ua rau bypass notch slugs rub? Ob peb mechanisms ua hauj lwm ib leeg los yog ua ke:

• Vacuum effect:Slugs generated thaum xuas nrig ntaus tsim me ntsis curvature. Huab cua daig hauv qhov khoob ntawm slug thiab lub ntsej muag lub ntsej muag tsim lub tshuab nqus tsev ib nrab thaum lub sijhawm thim rov qab. Lub kaw ntom nti nyob ib ncig ntawm lub punch perimeter tiv thaiv huab cua los ntawm kev nkag, thiab qhov nqus tuav tuav lub slug tiv thaiv lub punch.
• Kev txiav tawm ntau dhau:Thaum xuas nrig ntaus-rau- tuag clearance khiav ntawm sab siab, lub slug xaus me ntsis me dua lub matrix qhib. Nws tsis muaj xovxwm - haum cuam tshuam los tuav nws hauv qhov tuag, yog li nws tuaj yeem taug kev ywj pheej nrog lub punch thaum tshem tawm.
• Magnetism:Ferrous slugs txiav los ntawm carbon steel los yog stainless sawb tuaj yeem ua raws li cov hlau nplaum xuas nrig. Punches hauv av ntawm sib nqus nto grinders khaws cov hlau nplaum seem uas nyiam cov slug ntawm txhua lub voj voog.
• Hnav los yog degraded ejector springs:Ntau qhov chaw bypass thaib siv caij nplooj ntoos hlav -loaded slug ejectors kom zoo thawb lub slug tawm ntawm lub ntsej muag lub ntsej muag. Thaum cov springs qaug zog los yog tawg, lub slug tsis muaj mechanical quab yuam counteracting lub nqus tsev vacuum thiab kev sib txhuam tuav nws mus rau lub punch.

Bypass notch slug rub teeb meem pib nrog kev txheeb xyuas cov txheej txheem twg dominates. Yog hais tias slugs rub tsis tu ncua thiab cov tuag khiav ferrous cov khoom, xyuas cov seem hlau nplaum ua ntej vim nws yog qhov yooj yim los kho. Lub demagnetizer thov tom qab txhua lub voj voog ntse tshem tawm qhov ua rau tag nrho. Rau lub tshuab nqus tsev-tsav rub tawm, cov cua me me drilled los ntawm qhov nruab nrab ntawm qhov ntsuas phoo ntiv tes tawg lub foob. Rau kev tshem tawm-cov teeb meem ntsig txog, xav txog qhov thim rov qab-taper tuav khawm uas tuav cov slugs hauv compression hauv matrix.

Burr tsim yog qhov teeb meem thib ob nyob rau hauv qhov tsis zoo bypass notches. Raws li cov ntawv xuas nrig ntaus thiab tuag hnav ntau tshaj kaum tawm txhiab lub voj voog, qhov kev txiav tawm kom zoo maj mam nce. Qhov loj dua qhov kev tshem tawm loj dua, cov khoom siv ntau dua los ntawm qhov tuag ntug ua ntej tawg, ua rau cov kab mob siab dua nyob rau ntawm ntug ntug.

Vim li cas qhov no tseem ceeb rau bypass notch muaj nuj nqi? Ib qho burr uas tig los ntawm cov kab nrib pleb ua tau zoo txo ​​qhov kev tshem tawm ntawm ntug kab txaij thiab cov khoom siv tuag lub thais yog tsim los hla. Ib qho 0.1 hli burr rau ntawm qhov ntswj thawj tsim nrog 0.3 hli ntawm cov npoo tshem tawm txo koj cov npoo zoo los ntawm ib qho - thib peb. Nyob rau lub voj voog txaus, qhov kev loj hlob ntawm ib leeg tuaj yeem coj cov sawb mus rau qhov sib cuam tshuam nrog kev tsim cov hlau los yog cov neeg tsav tsheb thaum lub sij hawm indexing.

Bypass notch burr tsim kho qhov kev txiav txim ua raws li ob txoj hauv kev: rov qab txiav cov kev tshem tawm los ntawm kev ua kom cov punch thiab tuag, los yog tswj burr kev taw qhia thaum lub sij hawm tuag tsim yog li burrs fim downward deb ntawm tej qhov chaw cuam tshuam. Orienting lub thais xuas nrig ntaus los txiav los ntawm sab saum toj nto ntawm lub sawb thawb lub burr mus rau hauv qab ntug, qhov twg nws tej yaam num deb ntawm overhead tuag Cheebtsam es tsis yog rau lawv.

Misfeed tej yam kev mob tshwm sim los ntawm Notch cuam tshuam

Thaum ib tug bypass thais tsis muab txaus clearance, lub sawb catches ntawm ib tug tuag tivthaiv thaum indexing. Qhov tshwm sim yog ib qho misfeed: lub strip tsis ua rau tag nrho cov programmed suab, los yog nws nce mus, tab sis nrog rau sab nraud los yog angular skew. Ob qho xwm txheej txhais tau hais tias cov xovxwm tom ntej no ntaus ib qho chaw tsis raug cai, ua cov khoom seem zoo tshaj plaws thiab tuag kev puas tsuaj rau qhov phem tshaj.

Ib qho misfeed tshwm sim los ntawm bypass notch cuam tshuam tsis tshua tshwm sim raws li ib qho xwm txheej txaus ntshai. Nws feem ntau tsim maj mam raws li cov xwm txheej degrade dhau ntawm kev tsim khoom. Paub txog cov cim qhia thaum ntxov tso cai rau koj los cuam tshuam ua ntej qhov xwm txheej nce mus rau kev puas tsuaj tuag.

Diagnostic indicators, As point to notch interference as the misfeed source muaj xws li:

• Cov cim tsis sib haum xeeb:Tshawb xyuas cov kab nrib pleb ntawm cov chaw nres tsheb rau cov pov thawj cov cim tseg los ntawm cov kws tsav dav hlau thaum kho. Yog tias cov cim ntsuas pom qhov sib txawv ntawm qhov tob lossis kev taw qhia los ntawm kev mob stroke mus rau mob stroke, lub sawb tuaj txog ntawm txoj haujlwm tsis sib xws, qhia tias nws tau ntes thiab tso tawm tsis tau tshwm sim thaum lub sijhawm ntsuas.
• Pilot qhov elongation:Thaum cov kws tsav dav hlau yuav tsum yuam kom kho ib txoj hlua uas tsis tau ua tiav, lawv thawb cov khoom ntawm tus tsav lub qhov ciam teb dhau nws qhov kev txwv elastic. Tshaj rov qab kho, tus tsav lub qhov elongates nyob rau hauv cov kev taw qhia pub. Oval pilot qhov pom thaum lub sij hawm soj ntsuam sawb yog ib qho kev qhia meej ntawm kev cuam tshuam txog kev noj qab haus huv.
• Sawb ntug kev puas tsuaj qauv:Saib ntawm tus cab kuj ncaj qha rau ntawm qhov chaw thaib. Scraping marks, burnishing, los yog cov khoom smearing raws phab ntsa ntawv qhia tias lub sawb yog rub tawm tsam ib tug tuag tivthaiv thaum mus ncig. Qhov chaw thiab kev taw qhia ntawm cov cim no qhia koj raws nraim qhov twg yog qhov cuam tshuam.
• Intermittent sensor mus ncig:Yog tias koj tuag siv lub ntsuas ntsuas misfeed, qhov kev mus ncig tsis sib xws uas tsis cuam tshuam rau cov teeb meem pub noj zaub mov feem ntau taug qab rov qab mus rau qhov kev tshem tawm marginal. Lub sawb tau nce mus rau ntau lub sijhawm tab sis dai qee zaus thaum cov xwm txheej zoo sib xws, xws li thaum cov khoom siv thicker me ntsis los yog tuag kub peaks.

Peb lub hauv paus ua rau account rau feem ntau cuam tshuam misfeeds:

Tsis txaus qhov tob tob ntawm qhov pib.Qhov ntsuas qhov ntsuas qhov ntsuas tsis txaus, thiab cov txheej txheem sib txawv, txawm tias cov khoom siv thickness khiav ntawm qhov kawg ntawm spec, me ntsis thermal expansion, los yog me me burr buildup, thawb lub clearance hauv qab xoom. Qhov kev kho yog rov-machining qhov chaw nres tsheb ntswj kom qhov tob, feem ntau yog 0.1 txog 0.2 hli dhau qhov qub specification.

Cov khoom tsim ntawm cov khoom siv tuag.Lubricant residue, oxide particles, los yog zoo hlau shavings sau nyob rau hauv lifters, tsim steels, los yog pilot lub cev nyob rau hauv ntau txhiab lub voj voog. Qhov kev tsim kho no ua rau muaj txiaj ntsig zoo rau lub hnab ntawv ntawm cov khoom tivthaiv, txo qhov sib txawv ntawm qhov sib txawv txawm tias qhov ntsuas tsis tau hloov pauv.
