Kev cai Precision Hlau Stamping Tuag; Stamping Tuag Rau Cov Khoom Siv Hauv Tsev

I. Cov yam ntxwv tseem ceeb ntawm cov khoom tseem ceeb rau stamping tuag
Cov khoom tseem ceeb ntawm stamping tuag feem ntau suav nrog cov tuag cores, tuag hauv paus, coj ncej, coj bushings, thiab kab noj hniav inserts. Cov khoom no yog ua los ntawm siab - hardness, hnav- cov ntaub ntawv resistant, yog ib qho nyuaj rau tshuab, thiab muaj cov kev cai nruj me ntsis rau qhov raug qhov ntev, geometric tolerances, thiab nto zoo. Tshwj xeeb, qhov ntev ntev ntawm cov cores tuag thiab cov kab noj hniav yuav tsum tau tswj tsis pub dhau ± 0.005mm, thiab qhov tseeb haum ntawm cov ncej thiab cov lus qhia bushings yuav tsum ncav cuag qib H6 / h5. Lub precision ntawm cov khoom no ncaj qha txiav txim siab lub neej tuag thiab tus nqi ntawm cov khoom stamped. Precision machining thiab standardized los ua ke yog cov ntsiab lus tseem ceeb tswj.

II. Kev siv tswv yim ntawm Precision Machining Technology rau Cov Khoom Tseem Ceeb

1. Kev xaiv khoom thiab ua ntej- kho
Cov khoom tseem ceeb yog ua los ntawm siab- lub zog tuag steels xws li Cr12MoV, SKD11, thiab H13. Tom qab cov khoom siv raw tuaj txog ntawm qhov chaw, lawv raug kuaj xyuas qhov tsis zoo kom tshem tawm cov kev suav nrog, tawg, thiab lwm yam tsis xws luag. Ua ntej machining, kev laus kev kho mob yog ua nyob rau hauv ib tug kub tswj ntawm 200-220℃rau 4-6 teev kom tshem tawm cov kev ntxhov siab nyob rau hauv cov khoom, txo deformation thaum lub sij hawm machining, thiab txhim kho machining stability.

2. Machining txheej txheem ua tiav
Cov txheej txheem machining txheej txheem ntawm "roughing - semi-finishing - finishing - final finishing" yog saws. Roughing sai tshem tawm ntau dua 80% ntawm cov khoom pub kom tsis txhob muaj kev ntxhov siab thaum ua tiav. Semi-tiav siv CNC milling, tawm ntawm 0.1-0.2mm tiav nyiaj pub dawb. Kev ua tiav siv kev sib tsoo high-precision, hluav taws xob tawm machining (EDM), thiab xaim EDM los xyuas kom meej tias qhov tseeb qhov tseeb thiab geometric tolerances ntawm cov khoom ua tau raws li cov qauv. Thaum lub sij hawm machining, cov cuab yeej carbide yog siv, thiab kev txiav ceev thiab pub tus nqi yog tswj, nrog rau qhov tshwj xeeb txias nruab nrab los tiv thaiv overheating thiab deformation ntawm cov khoom, xyuas kom meej machining raug.

3. Kev Tswj Xyuas Qhov Zoo
Tom qab ua tiav, precision sib tsoo thiab polishing txheej txheem yog ua haujlwm. Qhov saum npoo roughness ntawm cov tub ntxhais pwm thiab kab noj hniav yog tswj tau rau Ra Tsawg dua lossis sib npaug ntawm 0.2μm, thiab qhov roughness ntawm cov ncej thiab bushings yog Ra tsawg dua los yog sib npaug rau 0.025μm, txo qhov kev sib txhuam ntawm qhov chaw thiab txhim kho pwm hnav tsis kam. Cov chaw ua haujlwm tseem ceeb raug kho nrog cov roj nitriding lossis PVD txheej txhawm rau txhim kho qhov tawv tawv thiab txuas ntxiv lub neej ntev.
