Sheet hlau dabtsi yog khoov Thiab Punching tuag; Deep Drawing Parts Rau Hlau Stamping

I. Kev Taw Qhia

Composite stamping tuag tuaj yeem ua tiav ntau yam txheej txheem xws li blanking, sib sau, thiab khoov hauv ib qho kev lag luam stamping, txo tus naj npawb ntawm cov khoom hloov pauv, txhim kho kev tsim khoom thiab cov khoom sib xws, thiab yog cov khoom siv tseem ceeb hauv kev tsim khoom niaj hnub stamping. Lub laj thawj ntawm kev tsim qauv kev sib xyaw ua ke thiab kev tshawb fawb ntawm cov khoom siv sib txawv ntawm kev xaiv rau thaj chaw ua haujlwm ncaj qha txiav txim siab qhov ua tau zoo thiab kev ntseeg siab ntawm cov tuag. Daim ntawv no, raws li kev tsim khoom tiag tiag, qhia meej cov ntsiab lus tseem ceeb ntawm kev sib xyaw stamping tuag cov qauv kev sib koom ua ke thiab tsim cov txheej txheem xaiv cov khoom siv rau txhua qhov chaw ua haujlwm, muab kev siv rau kev lag luam xyaum.

II. Integrated Structural Design of Composite Stamping Dies

1. Integrated Design Concept: Integrating blanking, forming, and bending processes in the same die, adopting modular and standardized structural design, with each functional unit (blanking module, forming module, guiding module) txuas los ntawm standardized interfaces los xyuas kom meej kev sib koom tes, txo inter- txheej txheem kev twb kev txuas, thiab txhim kho ntau lawm efficiency.

2. Structural Optimization Strategy: Finite element analysis (FEA) yog siv los simulate cov kev ntxhov siab thaum lub sij hawm tuag stamping txheej txheem, ntsuam xyuas cov khoom siv kho tshuab, optimize qhov ntev ntawm cov kev ntxhov siab tseem ceeb -cov kabmob qhov chaw, thicken lub hauv paus tuag, thiab nce lub thickness ntawm reinforcing tav los txhim khu kev tuag rigidity thiab hnav tsis kam. Cov qauv tsim tuag suav nrog ua- nyob rau hauv cov cua kub dissipation raws txoj kab uas hla ntawm 1.0-1.5mm, sib npaug ntawm qhov sib sau thiab qhov khoob, ua ke nrog lub tshuab lubrication tsis siv neeg los xyuas kom meej tias qhov kub tuag yog tswj ntawm 50-80℃thaum lub sijhawm ua haujlwm, ua tiav kev ua haujlwm tag nrho.

III. Kev Ua Haujlwm Hauv Cheeb Tsam thiab Cov Cai Xaiv Cov Khoom Siv

1. Kev Ua Haujlwm Hauv Cheeb Tsam: Raws li qhov kev ntxhov siab thiab kev hnav thaum lub sijhawm tuag stamping, qhov tuag tau muab faib ua plaub qhov chaw ua haujlwm. Txhua qhov chaw muaj qhov sib txawv ntawm kev ua haujlwm thiab ib puag ncig, uas ua rau muaj qhov sib txawv ntawm cov khoom siv: Blanking Zone (lub luag haujlwm rau kev ua haujlwm blanking, nrog rau kev ntxhov siab thiab hnav hnyav), Forming Zone (lub luag haujlwm rau khoov thiab ncab kev ua haujlwm, yuav tsum tau rov deformation), Guiding Zone (lub luag haujlwm rau qhov chaw thiab kev taw qhia, yuav tsum tau muaj peev xwm ua kom muaj kev ruaj ntseg) - thiab kev txhawb nqa. ntawm qhov tuag, yuav tsum tau rigidity).

2. Cov txheej txheem xaiv cov khoom sib txawv: Qhov chaw blanking siv D2 lossis SKD11 siab -alloy cuab yeej steel, uas yog nqus quenched thiab cryogenically kho kom ua tiav hardness ntawm HRC58-62, kom ntseeg tau siab hardness thiab hnav tsis kam; qhov chaw tsim khoom siv H13 tuag steel, nrog rau kev tswj hardness ntawm HRC55-58 tom qab kev kho cua sov, ntsuas qhov toughness thiab qaug zog tiv thaiv kom tsis txhob tawg thaum lub sij hawm tsim; qhov chaw taw qhia siv GCr15 bearing steel nrog nitriding kev kho mob los txhim kho seem stability thiab hnav tsis kam; qhov chaw txhawb nqa siv 45 # carbon structural steel, uas yog quenched thiab tempered los xyuas kom meej rigidity thaum txo nqi.
