Kev cai hlau taub hau Drawing tuag; Aluminium Head Deep Drawing Tuag

I. Kev Tshawb Fawb Txog Kev Ua Haujlwm thiab Cov Txheej Txheem Kev Xav Tau

1. Cov yam ntxwv ua haujlwm ntawm cov khoom siv

- SKD11: High-carbon, siab-chromium txias ua haujlwm tuag steel. Cov ntsiab lus carbon siab, zoo heev hnav tsis kam thiab lub zog, haum rau kev tsim khoom siab - cuam tshuam, siab - hnav khaub thuas stamping tuag.

- Cr12MoV: Siab-carbon, siab-chromium, molybdenum-vanadium alloy cuab yeej steel. Kev ua tau zoo tag nrho, nrog kev sib npaug zoo ntawm kev hnav tsis kam thiab toughness.

Ob lub steels yog rhiab heev rau quenching thiab tempering kub tswj. Kev kho cua sov kom tsim nyog tuaj yeem ua kom cov khoom siv tau zoo tshaj plaws.

2. Cov txheej txheem yuav tsum tau ua

Quenching thiab Tempering Txheej Txheem Optimization Lub Hom Phiaj:

- Txhim kho hardness thiab hnav tsis kam, txuas lub neej tuag.

- Ua kom zoo ib yam thiab zoo hauv cov qauv ntawm cov khoom, txhim kho toughness thiab tawg kuj.

- Tswj deformation thiab residual kev nyuaj siab, kom ntseeg tau tias tuag seem raug.

II. Quenching txheej txheem optimization

1. Preheating thiab cua kub tswj

Preheating thiab cua sov yog qhov tseem ceeb heev los tiv thaiv workpiece thermal tawg thiab deformation. Multi-theem preheating tuaj yeem txo qhov kev ntxhov siab sab hauv, uas yog qhov tseem ceeb tshwj xeeb tshaj yog rau loj-size tuag. SKD11 yog quenched ntawm 1020 ~ 1050 degree, thiab Cr12MoV ntawm 1030 ~ 1080℃kom ua tiav austenitization.

2. Quenching nruab nrab xaiv

Qhov nruab nrab quenching cuam tshuam rau qhov txias txias thiab uniformity. SKD11 siv cov roj quenching los yog roj cua txias kom ceev kom lub hardness Ntau dua los yog sib npaug rau 60HRC thiab txo qhov kev pheej hmoo ntawm kev tawg. Cr12MoV tuaj yeem siv siab -siab atomization txias los txhim kho cov cua txias sib xws thiab tswj kev ntxhov siab sab hauv.

3. Txias tus nqi optimization

Tus nqi cua txias yog hloov kho los ntawm kev sib txuas cov lej simulation thiab ntsuas qhov tseeb los ua kom zoo dua cov microstructure sab hauv ntawm cov hlau. Ib qho kev ua kom txias txias yog tsim los ua kom muaj kev sib xyaw martensite, tsis txhob kub tawg, thiab txhim kho cov khoom siv tag nrho.

III. Tempering txheej txheem Optimization

1. Precise Control ntawm Tempering Kub thiab Sijhawm

Tempering txo cov khoom brittleness. Ob leeg SKD11 thiab Cr12MoV ntiav ob -theem tempering txheej txheem:

- Thawj-theem tempering kub: 550 ~ 600℃. High -kub tempering txo kev ntxhov siab.

- Thib ob-theem tempering kub: 180 ~ 220℃. Qhov no refines cov txheej txheem tempering thiab stabilizes microstructure.
