1.Qhov txheej txheem thiab pwm yuav tsum tau kho li cas?
Optimizing Blank Holder Force (BHF)
Lub hauv paus ntsiab lus: Nrhiav qhov zoo sib npaug ntawm kev tiv thaiv wrinkling thiab tearing. Tsis txaus tuav lub zog yuav ua rau wrinkling, thaum lub zog ntau dhau yuav ua rau tearing.
Kev Ua Haujlwm: Maj mam nce qhov khoob khoob khoob kom txog thaum wrinkles raug tshem tawm. Yog tias siv lub tog raj kheej nitrogen los yog hydraulic cushion, xyuas kom zoo ib yam thiab ruaj khov siab.
Tsim nyog Kos Beads
Kev Ua Haujlwm: Kev tswj xyuas qhov nrawm thiab ntws ntawm cov ntawv hlau rau hauv qhov tuag yog ib qho tseem ceeb ntawm kev kho cov khoom siv hauv zos.
Kev daws:
Ntxiv los yog tsa cov hlaws dai rau hauv cov cheeb tsam uas ua rau wrinkling (xws li ze ntawm cov ces kaum tuag los yog thaj chaw tiaj tus).
Txo lossis tshem tawm cov hlaws dai rau hauv thaj chaw uas xav tau cov ntaub ntawv du (xws li lub kaum ntse ntse).
Siv segmented kos hlaws dai rau kev tswj hwm ntawm thaj chaw sib txawv.
Kho qhov tuag Clearance
Qhov kev tshem tawm tuag ntawm ib sab yog feem ntau 1.1 ± 0.1 npaug ntawm cov ntawv hlau tuab. Kev tshem tawm ntau dhau ua rau tsis muaj zog ntawm cov ntawv hlau, ua rau wrinkling.
Xyuas thiab xyuas kom meej tias qhov kev tshem tawm ntawm cov punch thiab tuag yog ib yam.
2.Yuav tsum tswj cov khoom thiab lubrication li cas?
Xaiv cov khoom zoo
Cov ntaub ntawv uas muaj plasticity siab thiab siab coefficient ntawm thickness anisotropy (r-tus nqi) muaj zog tiv thaiv wrinkling. Qhov siab r- tus nqi txhais tau hais tias cov ntawv hlau tsis tshua muaj qhov ua rau nyias nyias nyob rau hauv cov kev taw qhia tuab thiab ntws yooj yim dua nyob rau hauv cov kev taw qhia.
Tsim Nyog Cov Khoom Thickness: Nyob rau hauv cov kev txwv tso cai los ntawm ib feem tsim, nce cov khoom thickness tuaj yeem txhim khu kev tiv thaiv tsis ruaj khov.
Optimizing Lubrication Strategy
Lub hauv paus ntsiab lus tseem ceeb: Lubricate thaj chaw uas cov khoom ntws xav tau; zam los yog txo cov roj lubrication hauv cov cheeb tsam uas xav tau kev tiv thaiv.
Kev ua haujlwm:
Siv cov roj nplua nyeem rau thaj chaw uas cov khoom yuav tsum tau ntws, xws li cov fillet tuag thiab qhov chaw sib cuag ntawm lub qhov khoob.
Tsis txhob lubricating rau sab saum toj ntawm cov punch los yog overhanging qhov chaw uas yuav ua rau wrinkling, vim qhov no ua rau muaj kev sib txhuam tsis zoo nyob rau hauv cov cheeb tsam no.
3.Dab tsi yog qhov ua rau wrinkling ntawm flange thiab cov kev daws teeb meem yog dab tsi?
Tsis muaj peev xwm tuav lub zog, ntau dhau tangential compressive kev nyuaj siab
Kev daws: Ua kom lub zog khoob khoob khoob
Ntxiv dag zog los yog ntxiv cov drawbeads sab nraud
4.Dab tsi yog qhov ua rau thiab kev daws teeb meem rau wrinkling ntawm sidewalls ntawm qhov chaw?
Cov pwm tshem tawm ntau dhau ua rau cov khoom tsis ruaj khov thiab raug tshem tawm hauv nruab nrab - huab cua.
Kho thiab txo cov pwm tshem tawm; optimize tuag vojvoog; nce cov txheej txheem pub rau kev tshem tawm tom ntej.
5.Dab tsi yog cov txheej txheem daws teeb meem thiab daim ntawv tshuaj xyuas?
Kauj Ruam 1: Txheeb xyuas cov khoom siv
Paub meej tias cov khoom tau dhau los ua kom txaus recrystallization annealing (piv txwv li, siab -temperature tempering) thiab muaj cov yas zoo (elongation).
Xyuas seb cov khoom thickness thiab qib raws li cov txheej txheem yuav tsum tau ua.
Kauj Ruam 2: Tshawb xyuas Cov Tuag thiab Cov Khoom Siv
Puas yog qhov tuag nto du thiab tsis puas?
Puas yog qhov khoob khoob khoob khoob khoob khoob khawm, kho tau, thiab ruaj khov? (Kos lub tog raj kheej nitrogen / hydraulic cushion)
Puas yog qhov tuag clearance uniform?
Kauj Ruam 3: Kho cov txheej txheem Parameter (Core)
Maj mam nce qhov khoob khoob khoob los ntawm qhov qis mus rau siab, saib qhov hloov pauv wrinkling.
Kho qhov teeb tsa drawbead (piv txwv li, siv shims los kho qhov siab).
Optimize lub lubrication cheeb tsam thiab roj kom muaj nuj nqis.
Kauj Ruam 4: Xav txog kev hloov tsim qauv
Yog tias cov txheej txheem saum toj no tsis zoo, sab laj nrog tus tsim qauv:
Ntxiv cov txheej txheem ntxiv los yog wrinkle -txo cov tav.
Hloov cov duab ntawm qhov chaw ntawm cov khoom kom tsis txhob muaj qhov chaw tiaj tus.
Yog tias tso cai, siv cov khoom siv nrog ntau dua r-tus nqi lossis cov khoom tuab me ntsis.
