Hlau yog leej niam ntawm kev lag luam thiab lub hauv paus ntawm kev tiv thaiv hauv tebchaws. Hlau stamping hardware khoom feem ntau muab faib ua ob pawg loj: kho vajtse loj thiab khoom me me. Cov khoom siv loj yog hais txog cov phaj hlau, cov khoom siv ntxiv, cov hlau tiaj tus, lub kaum ntse ntse thoob ntiaj teb, cov hlau channel, I-beams, thiab ntau yam khoom siv hlau. Cov khoom siv me me suav nrog cov khoom siv hauv tsev, cov ntawv hlau, xauv, ntsia hlau, hlau, hlau mesh, hlau txiav, khoom siv hauv tsev, thiab ntau yam cuab yeej, thiab lwm yam.
Cov kev cai yooj yim rau cov khoom siv hlau stamping: Los ntawm kev xav ntawm kev ua haujlwm stamping, cov khoom siv kho tshuab, qhov zoo ntawm qhov chaw, thiab cov tuab tuab ntawm cov khoom siv stamping yuav tsum ua raws li cov hauv qab no:
Cov ntaub ntawv siv rau blanking nyob rau hauv cov hlau stamping yuav tsum muaj cov yas txaus thiab tsis tshua muaj hardness los txhim kho qhov zoo ntawm cov seem seem thiab qhov tseeb. Cov ntaub ntawv mos muaj kev ua haujlwm zoo, thaum cov ntaub ntawv nyuaj (xws li stainless hlau thiab cov pa roj carbon siab) muaj qhov tsis zoo ntawm qhov tsis zoo. Cov ntaub ntawv nkig yog feem ntau tsim kua muag thaum blanking.
Cov khoom siv rau kev khoov yuav tsum muaj cov yas txaus, tsis tshua muaj zog, thiab siab modulus ntawm elasticity. Cov ntaub ntawv nrog cov yas zoo tsis tshua muaj kev khoov thiab tawg, thaum cov ntaub ntawv uas muaj zog qis zog thiab siab dua elastic modulus nthuav tawm tsawg dua springback.
Cov ntaub ntawv siv rau kev sib sib zog nqus nqus hlau stamping yuav tsum muaj cov yas zoo, qis qis zog thiab hardness, thiab qhov loj thickness orientation coefficient. Cov ntaub ntawv uas muaj siab hardness yog qhov nyuaj rau kev sib sib zog nqus nqus; cov ntaub ntawv uas tsis tshua muaj lub zog sib piv los yog loj thickness orientation coefficient yog yooj yim rau kev sib sib zog nqus kos.
