Kev Cai Precision Hlau Stamping Tuag Rau Cov Khoom Siv Hauv Tsev

I. Kev txheeb xyuas qhov ua rau khawb hauv Aluminium Alloy Stamping Tuag

Aluminium alloys muaj kev ua haujlwm siab, ua rau lawv yooj yim rau adhesion rau qhov tuag nto thaum lub sij hawm stamping, ua rau khawb thiab khawb. Aluminium alloys muaj plasticity zoo, thiab lawv cov fluidity siab thaum lub sij hawm txoj kev sib sau ua exacerbates kev sib txhuam thiab shearing ntawm tuag- cov khoom taw tes, ua rau tuag nto hnav. Unoptimized tuag qauv tsim ua rau cov ntaub ntawv ntws txoj kev concentration nyob rau hauv lub zos cheeb tsam kuj ua rau scraping. Rough tuag nto thiab tsis txaus lubrication ntxiv aggravate scraping.

II. Kev Tiv Thaiv thiab Tswj Kev Ntsuas rau Scratching hauv Aluminium Alloy Stamping Tuag

1. Optimize Die Design: Siv cov qauv sib npaug rau cov kab noj hniav tuag, txiav cov npoo, thiab cov chaw hloov pauv, nrog lub vojvoog ntawm 0.2-0.5mm, kom tsis txhob muaj cov fab ntse. Ntxiv cov ntawv qhia ntawm cov ntsiab lus tseem ceeb ntawm cov khoom ntws thiab tsim lubrication grooves nrog qhov dav ntawm 2-3mm thiab qhov tob ntawm 1-1.5mm txhawm rau txhim kho cov khoom ntws zoo, txo cov kev ntxhov siab hauv cheeb tsam, txo qis kev sib txhuam, thiab txo cov scraping.

2. Siv cov khoom siv pwm siab heev thiab cov cuab yeej kho mob saum npoo: Cov pwm punches thiab kab noj hniav yog ua los ntawm H13 lossis SKD11 siab -hardness coj-cov pwm resistant, lub tshuab nqus tsev quenched rau hardness ntawm HRC58-62; Qhov saum npoo yog kho nrog ion nitriding lossis TiN txheej, nrog cov txheej txheej nitriding ntawm 0.15-0.3mm thiab txheej txheej thickness ntawm 0.005-0.01mm, txhim kho pwm nto lubrication thiab hnav tsis kam, thiab tiv thaiv cov khoom adhesion rau pwm.

3. Tsim nyog tus txheej txheem parameter tswj: Lub stamping ceev yog tswj ntawm 10-30 zaug / feeb, thiab lub stamping siab yog teem raws li lub thickness thiab tensile lub zog ntawm aluminium alloy cov ntaub ntawv, nrog ib tug yuam kev tsis pub tshaj ± 5%, xyuas kom meej cov khoom ruaj khov thiab txo deformation tsis sib xws; ua ntej pib lub tshuab txhua hnub, cov pwm saum npoo yog ntxuav los ntawm cov hlau filings thiab impurities, thiab cov pwm saum npoo yog polished txhua lub limtiam nrog polishing compound kom muaj qhov roughness Ra tsawg dua lossis sib npaug li 0.8μm, tsis txhob hnav thiab tsim kua muag.

4. Daim ntawv thov ntawm cov kev daws teeb meem zoo tshaj plaws: Siv cov roj nplua nyeem tshwj xeeb rau cov txhuas alloys, thiab muab qhov tseem ceeb rau cov dej tsis zoo hauv ib puag ncig-raws li cov roj stamping (cov roj cov ntsiab lus tsawg dua lossis sib npaug li 5%) lossis cov roj nplua nyeem (graphite, PTFE). Txau tusyees ntawm cov pwm kab noj hniav thiab aluminium alloy nto ua ntej stamping los xyuas kom meej lubrication txaus. Thaum nruam stamping, ntxiv roj nplaum txhua 30-50 daim los tswj cov coefficient ntawm kev sib txhuam kom tsis pub dhau 0.1, yog li txo cov pwm coj thiab khawb ntawm cov txhuas alloy nto.
