High-frequency hardening tshuab yog siv rau induction hardening ntawm pob screws
High-zaus hardening tshuab yog siv rau induction hardening ntawm pob screws
Pob ntsia hlau yog ib qho kev ua haujlwm dov uas hloov cov lus tsa suab thiab cov lus tsa suab. Nws muaj lub luag haujlwm ntawm kev sib kis tau yooj yim thiab qhov tseeb qhov chaw. Nws tau dav siv nyob rau hauv lub tshuab cuab yeej kis tau tus mob, cov khoom siv lej tswj, kev tswj tsis siv neeg thiab lwm yam. Tom qab quenching, cov ntsia hlau muaj siab hardness thiab siab brittleness, thiab kev kho kev ua hauj lwm yog ib qho nyuaj, uas yog tsis conducive rau huab hwm coj ntau lawm ntawm cov khoom. Yog li ntawd, nws yuav tsum nruj me ntsis tswj txoj kab uas hla dhia ntawm cov ntsia hlau thaum quenching. Qhov yuav tsum tau muaj rau cov nqi ntawm lub suab deformation yog raws li qhov tseeb tias feem ntau ntawm cov pob ntsia hlau ntau lawm ntawm kev lag luam dav dav yog qhib txoj kev sib tw thiab tom qab ntawd quench.
Cov txheej txheem yooj yim ntawm induction hardening ntawm lub pob ntsia hlau nto: Rau quenching lub pob ntsia hlau raceway, quenching inductor uas phim qhov loj ntawm cov ntsia hlau yuav tsum tau ua. Cov txheej txheem kev kho cua sov tsis zoo: austenitizing kub ntawm 860 ~ 880 ℃, tom qab kev kho dej khov txias Hauv kev ua haujlwm tom ntej lossis siv lub pob ntsia hlau, tsis muaj qhov tshwm sim uas cuam tshuam rau qhov tseeb qhov tseeb vim qhov hloov pauv ntawm cov qauv. Los ntawm ntau cov txheej txheem kev xeem, kom ntseeg tau tias muaj kev ntseeg siab thiab ruaj khov ntawm cov txheej txheem ntau lawm. Rau txhua lub pob screws, cov txheej txheem kev xeem yog thawj zaug ua raws li cov qauv thiab qhov xav tau qhov tob ntawm cov txheej txheem quenched hardened, thiab cov txheej txheem parameter hloov ntau yam yog txiav txim siab. Qhov thib ob, hauv kev tsim khoom tiag tiag, nws yuav tsum tau kho kom zoo nyob rau hauv qhov ntsuas qhov ntsuas kom ua kom lub zog quenching thiab pitch deformation ntawm cov ntsia hlau txhuas ua tau raws li qhov yuav tsum tau ua.
