Kev cai Precision Automotive Stamping Tuag, Txhuas Thiab Stainless Stamping Tuag, Progressive Stamping Tuag

I. Precision Manufacturing txheej txheem ntawm stamping tuag

1. Tsim Theem: Raws li 3D kos duab thiab kev ua tau zoo ntawm cov khoom siv stamping, 3D qauv ntawm cov tuag tiav siv CAD / CAE kev sib koom tes tsim platform. Finite element tsom xam yog siv los kwv yees tuag kev nyuaj siab deformation thiab ib feem ntawm kev ua tsis xws luag, optimizing lub tuag qauv, kab noj hniav qhov ntev, thiab qhia layout kom ntseeg tau tias tuag lub rigidity thiab durability raws li cov qauv, thiab stamping raug yog tswj nyob rau hauv ± 0.005mm, thaum tib lub sij hawm txo cov tuag manufacturing thiab tom qab tu cov nqi.

2. Raw Material Preparation: Cov khoom tseem ceeb tuag yog ua los ntawm siab -kev ua tau zoo alloy steels xws li SKD11, DC53, thiab cemented carbide. Tom qab cov khoom siv raw tuaj txog, kev kuaj xyuas qhov tsis zoo yog ua kom tshem tawm cov kev suav nrog, tawg, thiab lwm yam tsis xws luag. Tom qab ntawd, lub tshuab nqus tsev quenching + sib sib zog nqus cryogenic kev kho mob + qis -kub tempering yog siv los tswj qhov hardness rau HRC58-62, tau txais ib tug zoo microstructure los xyuas kom meej ib tug du mus rau tom ntej precision machining.

3. Precision Machining: Cov txheej txheem kev loj hlob ntawm "nplua nuj machining - semi-finishing - finish machining" yog saws. Ua ntej, feem ntau ntawm cov khoom siv ntau dhau raug tshem tawm los ntawm CNC milling, qeeb hlau EDM, thiab sab nraud cylindrical sib tsoo. Tom qab ntawd, hluav taws xob tso tawm machining (EDM) yog siv los kho cov kab noj hniav, micro- qhov, thiab cov qauv tsis sib xws, kom ntseeg tau tias cov pwm kab noj hniav qhov ntev qhov tseeb yog nyob rau hauv ± 0.003mm thiab qhov chaw roughness Ra tsawg dua los yog sib npaug rau 0.025μm, ua tau raws li qhov yuav tsum tau muaj ntawm precision stamping.

4. Sib dhos thiab Debugging: Tom qab ultrasonic tu thiab deburring, cov pwm qhov chaw tau sib sau ua ke hauv qab no: "pwm puag → coj ncej thiab bushings → kab noj hniav inserts → ejector mechanism." Lub dial taw qhia yog siv los xyuas qhov haum clearances, kom ntseeg tau tias qhov haum raug ntawm txhua feem mus txog H6 / h5. Thaum lub sij hawm sim molding, cov pwm raug ntsia rau ntawm cov khoom siv stamping, ib qho kev xeem ntawv ua tiav, thiab lub caij nplooj ntoos hlav quab yuam, kev taw qhia clearance, thiab stamping force parameters raug kho kom txog rau thaum lub stamped qhov ntev thiab nto zoo raws li cov qauv.

5. Kev soj ntsuam zoo: Lub tshuab ntsuas kev sib koom tes (CMM) yog siv los ua kev soj ntsuam zoo ntawm cov pwm kab noj hniav qhov ntev thiab geometric tolerances, txheeb xyuas qhov sib txawv ntawm cov duab kos duab. Nyob rau tib lub sijhawm, cov pwm qhia qhov tseeb thiab kev sib dhos tshem tawm raug kuaj xyuas. Cov khoom tsis raug raug rov ua haujlwm tam sim kom muaj kev ruaj ntseg thiab ua haujlwm ntawm cov pwm thaum lub sijhawm tsim khoom loj. Cov pwm kev pabcuam lub neej yog ntau dua lossis sib npaug rau 500,000 cycles.

II. Kev piav qhia ntxaws txog txheej txheem stamping

1. Kev npaj thiab txiav cov khoom: Raws li cov kev qhia tshwj xeeb ntawm cov khoom stamped, txias- dov steel phaj, stainless hlau phaj, aluminium alloy phaj, thiab lwm yam, raug xaiv los ua raw khoom. Cov phaj yog uncoiled los ntawm ib tug uncoiler thiab sheared los ntawm ib tug shearing tshuab los ua lawv rau hauv qhov ntev haum rau pwm. Qhov ntev ntev ntawm daim hlau yog tswj nyob rau hauv ± 0.1 hli, thiab qhov saum npoo yog dawb ntawm khawb thiab oxide nplai kom tsis txhob cuam tshuam cov stamping zoo.

2. Kev Tso Cai thiab Clamping: Kev sib xyaw ua ke ntawm cov ntawv qhia, sab hniav, thiab cov pins ntab yog siv los ua cov cuab yeej taw qhia, nrog rau cov clamps tshwj xeeb, txhawm rau txhim kho cov phiaj xwm hauv txoj haujlwm ntawm cov pwm. Qhov tseeb ntawm qhov chaw yog tsawg dua lossis sib npaug li ± 0.01mm, tiv thaiv kev poob thiab deformation ntawm daim hlau thaum lub sij hawm stamping, kom ntseeg tau qhov chaw zoo ib yam rau txhua qhov stamped, thiab txhim kho kev ruaj ntseg ntawm cov khoom loj.

3. Blanking thiab Forming: Los ntawm kev koom tes ntawm cov punch tuag thiab cov kab noj hniav, cov txheej txheem xws li blanking, sib sib zog nqus nqus, dabtsi yog khoov, thiab flanging yog ua tiav los ua cov ntawv hlau rau hauv lub hom phiaj. Kev tsim khoom loj tau txais cov txheej txheem stamping thiab nruam stamping txheej txheem, kev sib koom ua ke ntau cov txheej txheem rau hauv ib qho. Lub stamping zaus yog tswj ntawm 30-120 zaug / feeb los txhim kho kev tsim khoom thaum ua kom ntseeg tau qhov sib xws ntawm qhov chaw stamped.

4. Kev kho thiab ua tiav: Tom qab stamping, cov khoom yog hauv av thiab polished kom tshem tawm ntug burrs, nrog burr qhov siab tswj tsis pub dhau 0.01mm. Rau qhov chaw nrog me ntsis deformation, lub tshuab straightening yog siv los txhim kho lawv, kom ntseeg tau tias qhov flatness thiab perpendicularity ntawm cov khoom ua tau raws li cov qauv, thiab qhov roughness ntawm qhov tsawg dua los yog sib npaug li 0.8μm, ua tau raws li qhov yuav tsum tau ua ntawm kev sib dhos tom ntej.

5. Kev Tshuaj Xyuas Zoo: Kev sib xyaw ntawm cov khoom siv tshuaj ntsuam xyuas tsis siv neeg thiab cov qauv siv phau ntawv yog siv los tshuaj xyuas qhov loj me thiab qhov zoo li ntawm qhov chaw stamped. Yog tias qhov sib txawv ntawm qhov sib txawv tshaj qhov kam rau ua tsawg dua lossis sib npaug ntawm ± 0.02mm, lub tshuab raug nres tam sim ntawd thiab cov pwm tsis raug kho. Kev tshuaj xyuas qhov tshwm sim tsom mus rau kev kuaj xyuas qhov tsis xws li khawb, khawb, thiab deformation kom ntseeg tau tias qhov dhau ntawm cov khoom stamped yog ntau dua lossis sib npaug li 99.5%, thiaj li muab cov khoom tsim nyog ib nrab- cov khoom tiav rau cov txheej txheem tom ntej.
