Hlau stamping yog ib txoj kev siv dav siv hauv kev tsim khoom, thiab nws cov ntsiab cai tseem ceeb suav nrog ntau yam xws li cov khoom siv tshuab, plasticity mechanics, thiab tribology.
Lub hauv paus ntsiab lus ntawm cov hlau stamping yog siv lub stamping xovxwm los tso cov ntawv hlau ntawm qhov tuag, thiab siv lub zog los ua cov yas deformation ntawm cov hlau, yog li tau txais ib feem ntawm qhov xav tau thiab qhov loj me. Thaum lub sij hawm stamping txheej txheem, cov ntawv hlau yog raug rau lub siab, ua rau nws sab hauv grain qauv rau rearrange, ua tiav cov khoom ntws thiab tsim. Cov txheej txheem yas deformation no yog thim rov qab, txhais tau tias thaum lub zog sab nraud raug tshem tawm, cov ntawv hlau tseem tuaj yeem rov qab mus rau nws qhov qub. Txawm li cas los xij, thaum lub sij hawm stamping txheej txheem, cov hlau yuav raug kev puas tsuaj rau qee yam, ua rau muaj kev hloov pauv ntawm nws cov khoom siv kho tshuab thiab qhov chaw zoo.
Cov txheej txheem hlau stamping yuav tsum muaj xovxwm stamping thiab tuag. Lub stamping xovxwm yog cov cuab yeej uas muab lub zog stamping; nws txoj haujlwm ua haujlwm yog siv hydraulic lossis pneumatic kis tau tus mob los ua ib qho swb txav reciprocatingly linearly ntawm ib qho kev qhia rail, yog li paub txog kev ua haujlwm ntawm cov ntawv hlau. Cov tuag yog cov khoom tseem ceeb uas txiav txim siab qhov zoo thiab qhov loj ntawm qhov, thiab nws cov qauv tsim thiab kev tsim khoom ncaj qha cuam tshuam rau qhov zoo ntawm qhov chaw stamped. Thaum lub sij hawm stamping txheej txheem, kev sib txhuam ntawm cov tuag thiab cov ntawv hlau kuj yog ib qho tseem ceeb cuam tshuam rau cov nyhuv stamping.
