1.Dab tsi yog qhov laj thawj tseem ceeb rau kev tshuaj xyuas no?
Lub lubrication tsis txaus los yog ua tsis tau tiav: Lub siab zoo - thiab shear- tiv thaiv thaiv tsis tuaj yeem tsim ntawm qhov tuag thiab cov ntawv hlau.
Kev tuag tsis zoo: Cov tawv tawv tsis zoo, roughness, lossis cov khoom siv, tsis tiv thaiv adhesion.
Cov khoom vaj khoom tsev tsis sib haum: Cov txheej txheem saum npoo los yog cov khoom siv ntawm cov ntawv hlau nws tus kheej tsis tsim nyog rau cov txheej txheem stamping no.
Cov txheej txheem tsis tsim nyog: Cov txheej txheem nruj heev, ua rau muaj kev sib txhuam thiab kub nce.
2.Yuav ua li cas kom zoo lubrication?
Txhim kho Lubricants:
Ua kom muaj viscosity lossis siv cov khoom siv siab heev: Siv cov roj tshwj xeeb stamping / lubricants uas muaj cov khoom siv siab (EP) ntxiv xws li chlorine, sulfur, thiab phosphorus. Nyob rau hauv lub siab, cov additives reacts nrog cov hlau los tsim ib tug shear- resistant tshuaj tiv thaiv zaj duab xis.
Hloov Lubricant Hom: Hloov los ntawm cov roj-raws li cov roj pleev xim qhuav, siv quav ciab-raws li lubricants, los yog cov txheej txheem polymer, uas muab cov txheej txheej tiv thaiv tuab dua.
Xyuas kom huv huv: Tiv thaiv kom tsis txhob muaj roj nplua nyeem los yog kev taw qhia ntawm impurities.
Txhim kho txheej txheej txheej thiab tus nqi:
Uniform thiab txaus daim ntawv thov: xyuas kom zoo ib yam thiab txaus lubricant kev pab them nqi nyob rau hauv deformed cheeb tsam ntawm daim ntawv hlau (tshwj xeeb tshaj yog flange cheeb tsam).
Muab ob npaug rau-Sided Txheej: Siv cov roj nplua nyeem rau ob sab ntawm cov ntawv hlau, tshwj xeeb tshaj yog rau qhov sib sib zog nqus- kos.
Tuag Txau: Hauv kev tsim khoom tas mus li, ntxiv cov roj tsis siv neeg tuag / siv quav ciab txau.
3.Yuav ua li cas txhim kho cov pwm pwm?
Txhim kho Mould Surface Hardness thiab Smoothness:
Kev Kho Hniav: Siv TD kev kho mob (vanadium / niobium infiltration hauv ntsev da dej) lossis PVD / CVD txheej (xws li CrN, TiCN, DLC pob zeb diamond-zoo li carbon txheej) rau pwm. Cov kev kho mob no txhim kho qhov tawv tawv, hnav tsis kam, thiab tiv thaiv- adhesion ntawm pwm, ua rau lawv yog ib txoj hauv kev zoo tshaj plaws los daws qhov teeb meem ntawm siab - lub zog hlau thiab stainless hlau nplaum rau pwm.
Nto Polishing: Polish qhov chaw ua hauj lwm ntawm cov pwm (tshwj xeeb tshaj yog cov kab sib npaug) mus rau ib daim iav tiav (Ra Tsawg dua los yog sib npaug li 0.2μm) kom txo tau khawb ntawm cov ntawv hlau los ntawm microscopic protrusions.
Optimizing Pwm Khoom:
Siv cov hmoov nplej siab- ceev steel los yog cemented carbide inserts nyob rau hauv qhov chaw tseem ceeb, vim lawv muaj hardness ntau dua thiab liab hardness.
Txhim khu Mould Maintenance:
Kev Tu Tsis tu ncua: Tshem tawm cov hlau me me uas ua rau pwm (siv tooj liab lossis tooj dag scrapers kom tsis txhob ua rau pwm substrate).
Xyuas kom txias: Tsim cov cua txias hauv pwm los tswj pwm kev ua haujlwm kub thiab tiv thaiv cov roj nplua nyeem tsis ua haujlwm vim qhov kub thiab txias.
4.Yuav kuaj xyuas thiab kho cov ntaub ntawv li cas?
** Paub meej tias Nto Roughness:** Tshawb xyuas qhov roughness ntawm qhov chaw (Ra tus nqi) ntawm qhov txias -rolled coil. Qhov saum npoo du heev (Ra tus nqi qis dhau) muaj peev xwm khaws cov roj tsis zoo, yooj yim ua rau lubrication tsis ua haujlwm; ib qho chaw ntxhib heev yuav ua rau muaj kev sib txhuam. Feem ntau, txias- cov ntawv dov rau stamping muaj qhov haum roughness ntau yam.
** Txheeb xyuas qhov huv huv:** Paub meej tias cov ntawv hlau saum npoo yog tsis muaj cov roj seem seem, xeb- tiv thaiv cov roj, lossis cov kab mob, uas tuaj yeem cuam tshuam tsis zoo nrog cov roj stamping.
** Txheeb xyuas cov khoom siv tshuab:** Paub meej tias cov khoom siv lub zog tawm los, lub zog tensile, n- tus nqi (hardening index), thiab r- tus nqi (plastic strain ratio) ua tau raws li qhov yuav tsum tau ua. Cov ntaub ntawv uas mos dhau los yog tawv dhau tuaj yeem ua rau muaj kev nyuaj siab thiab ua rau muaj kev pheej hmoo ntawm pwm nplaum.
5.Yuav ua li cas rau optimize stamping txheej txheem tsis?
Txo lub zog tuav lub zog: Siv lub zog qis tshaj plaws ntawm lub cev tsis muaj zog thaum ua kom tsis muaj wrinkling kom txo cov kev sib txhuam tsis sib haum hauv thaj tsam flange.
Kho qhov kev tshem tawm: Tshawb xyuas thiab ua kom zoo dua qhov kev tshem tawm ntawm qhov punch thiab tuag. Tsis txaus clearance yuav exacerbate shearing thiab scraping.
Tswj stamping ceev: Tsim nyog txo stamping ceev kom txo qis tam sim no kub kub uas tsim los ntawm siab - kev sib txhuam ceev.
Txhim kho kos cov hlaws tsim: Ua kom zoo dua lub vojvoog thiab qhov siab ntawm cov hlaws dai kom yooj yim rau cov khoom siv smoother thiab txo cov kev sib txhuam loj hauv cheeb tsam.
