Hlau casing, tiv thaiv npog stamping qhov chaw, hlau stamping tuag

Cov khoom siv yog qhov tseem ceeb tshaj plaws rau kev txiav txim siab qhov zoo ntawm qhov chaw stamped. Nws cov khoom muaj nyob hauv thiab qhov chaw ntawm qhov chaw ncaj qha txiav txim siab qhov tsis kam rau deformation thiab qhov chaw ruaj khov thaum lub sij hawm stamping txheej txheem. Ntawm ib sab tes, cov khoom siv ntawm cov khoom siv, xws li cov khoom muaj zog, elongation, thiab hardness, ncaj qha cuam tshuam qhov sib xws ntawm cov yas deformation thaum lub sij hawm stamping. Yog hais tias lub zog tawm los yog siab dhau lawm, qhov kev ntxhov siab hauv zos yuav tshwm sim thaum lub sij hawm stamping, ua rau cov kab nrib pleb; thaum tsis txaus elongation yuav tiv thaiv cov khoom ntawm stretching tusyees thaum lub sij hawm stretching txheej txheem, ua rau nto wrinkling los yog tawg. Cov teeb meem no ncaj qha ua rau lub ntsej muag zoo.

Ntawm qhov tod tes, qhov zoo ntawm cov khoom nws tus kheej yog qhov tseem ceeb tshaj. Kos, nplai, xeb, roj stains, thiab lwm yam tsis xws luag nyob rau saum npoo ntawm cov khoom siv raw yuav tau nthuav dav thaum lub sij hawm stamping txheej txheem thiab xa ncaj qha mus rau saum npoo ntawm lub stamped ib feem, tsim qhov tsis xws luag uas nyuaj rau kho. Piv txwv li, yog tias cov oxide txheej nyob rau saum npoo ntawm qhov txias - dov steel ntawv tsis huv huv, cov oxide txheej yuav poob tawm thiab embed rau hauv lub workpiece nto thaum lub sij hawm stamping, tsim pits; thaum cov roj stains adhering rau saum npoo yuav ua rau lub lubrication tsis sib luag thaum lub sij hawm stamping, nce kev sib txhuam ntawm cov tuag thiab cov khoom, ua rau nto khawb. Yog li ntawd, kev xaiv cov khoom zoo - zoo raw khoom thiab nruj nreem nto pretreatment yog thawj kab ntawm kev tiv thaiv nyob rau hauv kom ntseeg tau lub nto zoo ntawm stamped qhov chaw, txiav txim siab qhov pib ntawm nto zoo txij thaum pib.

Raws li cov neeg nqa khoom tseem ceeb ntawm cov txheej txheem stamping, tus tsim precision, kev tsim khoom zoo, thiab kev saib xyuas ntawm tus tuag ncaj qha txiav txim siab qhov zoo ntawm qhov chaw stamped. Kev tuag tshem tawm yog ib qho ntawm cov tseem ceeb tsis cuam tshuam rau qhov zoo ntawm qhov chaw. Yog hais tias qhov clearance loj dhau lawm, cov khoom yuav tsim kua muag thaum lub sij hawm stamping, ua rau ib tug ntxhib ntoo khaub lig-section, nce burrs, thiab txo nto smoothness. Yog tias qhov kev tshem tawm tsawg dhau, kev sib txhuam ntawm qhov tuag thiab cov khoom siv yuav hnyav dua, tsis yog tsuas yog hnav hauv qhov tuag saum npoo, tab sis kuj ua rau ntau dhau ntawm cov khoom nto, ua rau khawb, indentations, thiab cov khoom siv adhesion, ua rau muaj kev puas tsuaj loj heev.
