Kev Cai Precision Stamping Thiab Drawing Tuag Rau Oxygen cylinders Thiab Cov Cuab Yeej Me Me

I. Cov yam ntxwv kev ntxhov siab ntawm stamping tuag
Thaum lub sij hawm stamping txheej txheem, lub zog los ntawm kev tuag feem ntau suav nrog lub zog stamping, sab siab, kev sib txhuam, thiab lub zog springback. Stamping quab yuam yog lub ntsiab sab nraud quab yuam ua rau cov yas deformation ntawm lub workpiece, ncaj qha txiav txim siab lub zog ntawm cov qauv tuag; sab siab thiab kev sib txhuam cuam tshuam rau qhov tuag taw qhia qhov tseeb thiab cov khoom ntws hauv lub xeev; springback quab yuam txiav txim siab qhov tseeb qhov tseeb thiab tsim cov khoom zoo. Kev tsom xam tag nrho ntawm cov teeb meem kev ntxhov siab no yog qhov yuav tsum tau ua ua ntej rau kev tsim qauv ntawm cov qauv tuag.

II. Kev suav txheej txheem ntawm Stamping Force
Stamping quab yuam yog qhov tseem ceeb hauv kev tsim cov stamping, thiab nws qhov kev suav qhov tseeb ncaj qha txiav txim siab qhov tsim nyog ntawm tus tsim tuag. Ib qho kev kwv yees siv feem ntau yog raws li hauv qab no:

$$F=L × t × sigma_f$$
Qhov twg:

- $$F$$ yog lub zog stamping, hauv Newtons (N);

- $$L$$ yog qhov zoo shearing lossis punching ntev, hauv millimeters (mm);

- $$t$$ yog lub workpiece daim ntawv thickness, nyob rau hauv millimeters (mm);

- $$sigma_f$$ yog cov khoom txaus siab, hauv megapascals (MPa).

Flow stress yog coj raws li qhov nruab nrab ntawm cov khoom siv lub zog thiab lub zog tensile, uas qhia txog cov khoom siv dav dav thaum lub sij hawm yas deformation.

III. Kev txiav txim siab ntawm Side Pressure thiab Friction Side siab yog los ntawm kev sib txhuam thiab compression ntawm cov khoom ntawm cov pwm qhia seem, thiab nws cov nqi yog ib feem ntawm lub zog stamping. Kev ua kom zoo ntawm kev sib txhuam coefficient tuaj yeem txo qhov siab sab, txo pwm hnav, thiab ua rau lub neej pwm ntev. Siv lubricants thiab optimizing cov txheej txheem tsis yog txoj hauv kev tseem ceeb kom ua tiav qhov no.

Sab siab $$F_s$$ yog xam raws li nram no:

$$F_s=\\mu \\times F$$ Qhov twg $$\\mu$$ yog cov kev sib txhuam coefficient, txiav txim siab raws li cov khoom nto thiab lubrication tej yam kev mob, nrog ib tug nqi ntau ntawm 0.1 ~ 0.3.

IV. Kev pov thawj ntawm Mould Structural Strength Tom qab txiav txim siab lub zog stamping thiab lwm yam kev ntxhov siab, nws yog ib qho tsim nyog yuav tsum tau ua qhov kev ntsuam xyuas quab yuam ntawm cov pwm pwm tseem ceeb los xyuas kom meej tias tsis muaj cov yas deformation lossis qaug zog puas tsuaj hauv kev ntxhov siab. Siv finite element tsom xam (FEA) software, ua ke nrog cov ntaub ntawv kev ntxhov siab suav nrog, kev faib tawm kev ntxhov siab thaum lub sijhawm ua haujlwm pwm tuaj yeem raug simulated, muab lub hauv paus rau kev tsim kho kom zoo.

Xaiv cov khoom pwm tsim nyog thiab cov txheej txheem kho cua sov los txhim kho pwm qhov nyuaj, tawv, thiab hnav tsis kam yog ib qho tseem ceeb lav rau pwm kom tiv taus siab - siv zog stamping siab.
