Cov qauv rau cov ntsia thom khwm muaj xws li: lub npe (tus qauv), cov khoom, lub zog qib, specifications, thiab kev kho qhov chaw.
1. Nyob rau hauv cov nqe lus ntawm cov khoom hom, torsional lub zog ntawm hex screws yog tus loj dua, lub zog ntawm hex screws yog me, thiab lub zog ntawm lub hla qhov taub me me. Nyob hauv kev txhawb kev siv cov khoom, nws yog feem ntau pom zoo siv lub hau ntswj siab tshaj qhov theem ntawm cov txiv ntoo, yog li ntawd feem ntau pheej yig.
2, qhov khoom siv qib, ntawm no tsuas yog hais txog cov ciaj ntswj feem ntau siv cov hlau, raws li cov theem ntawm cov ntsiab lus ntawm cov ntsiab lus, muab faib rau: C1008 (sib piv rau 4.8), C1035 (sib piv rau 8.8), C1045 (sib piv rau 10.9), SCM435 (sib thooj li 12.9 Qib thiab 45H), qhov siab dua cov ntsiab lus ntawm carbon, qhov nyuaj cov khoom. Kev ntsuas ntawm chav kawm 8.8 mus rau saum toj no yog tag nrho cov cuab yeej siab.
3, xws li M4x8, 4 tus ntiv tes sab nraud 4 hli, 8 hais txog cov khoom ntim yog qhov ntev ntev ntawm 8 hli, feem ntau cov taub hau taub hau ntsia thawv muaj qhov ntev tag nrho, ib qho hluav taws xob ntswj ntxiv rau ib nrab ntawm lub taub hau ntev . Lub taub hau txawb taub hau tsis muaj lub taub hau loj.
4, tib cov ntaub ntawv rau kev kho cua sov, lub siab dua qhov nyuaj, lub zuj zus lub toughness. Kev kho cua sov yog tsim nyog rau kev tawm ntawm qib 8.8 mus rau saum toj. Tam sim no, muaj ob hom kev kho cua kub: cov cuab yeej ua kom siab yuav tsum quenching thiab tempering thaum tshav kub kub kho, uas yog, qhov nyuaj ntawm txoj hlua ntawm sab hauv mus rau sab nraud yog hom teeb meem; Tapping nws tus kheej yog xav tau kev kho mob ntawm kev kho cua kub, uas yog, cov nplais ntawm lub viav vias penetrates ib txheej ntawm carbon, heev zog, Tab sis sab hauv yog mos heev, thiab yog hais tias nws yog carburized mus rau sab hauv, lub hau yuav scorched.
5, Raws li ib txwm muaj, lub zog> 32HRC, plating hydrogen embrittlement. Thaum twg hydrogen embrittlement yog cov khoom khaws cia (roj tsuas), H + nkag rau cov hlau ua npuas, thiab cov ntsuas tau siv rau ntawm qhov chaw thiab ua txhaum tom qab 24 teev. Yog li, qhov hom ntawm cov khoom siv nrog rau cov kev muaj mob hla lub cev yuav tsum tau nqhis dej tom qab electroplating.
