Lub tshuab txias txias tau txais cov ntaub ntawv disc thiab ncaj nraim thiab siv lub hauv paus ntsiab lus ntawm kev ntxhov siab theem nrab los tsim ntau lub taub hau, countersunk taub hau, semi-countersunk taub hau, hexagon socket thiab lwm yam tsis yog-tus qauv lub taub hau bolts thiab txhua yam khoom.
Yog li dab tsi yog qhov yuav tsum tau ntawm lub tshuab taub hau txias rau nws cov khoom siv?
1. Cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab ntawm cov khoom siv raw rau lub taub hau txias ntawm lub tshuab pier txias yuav tsum ua raws li cov qauv tsim nyog.
2.Lub chaw tsim khoom ntawm ntau txoj hauj lwm txias taub hau tshuab piav qhia tias cov khoom raug kho los ntawm spheroidization annealing, thiab cov qauv metallographic ntawm cov khoom yog kheej kheej pearlite qib 4-6.
3. lub hardness ntawm raw cov ntaub ntawv, thiaj li yuav txo tau cov cracking nyiam ntawm cov khoom kom deb li deb tau, txhim kho lub neej kev pab cuam ntawm pwm kuj yuav tsum tau cov khoom siv txias txias muaj qhov qis hardness kom deb li deb li sai tau, txhawm rau txhim kho cov khoom siv. plasticity.Qhov hardness ntawm raw cov ntaub ntawv feem ntau yuav tsum nyob nruab nrab ntawm HB110 thiab 170 (HRB62-88).
4.txoj kev kos duab ntawm tag nrho cov ntiv tes qhov tseeb yuav tsum tau ua raws li cov kev cai tshwj xeeb ntawm cov khoom thiab cov txheej txheem txheej txheem, feem ntau hais lus, rau kev txo txoj kab uas hla thiab qhov loj ntawm qhov kev xav tau ntawm qhov tsawg dua.
5.Cov chaw tsim khoom ntawm kev kub ceev txias txias tshuab piav qhia tias qhov zoo ntawm cov khoom siv txias txias yuav tsum tau ua kom lub lubrication zaj duab xis yuav tsum tsaus thiab ci, thiab qhov saum npoo yuav tsum tsis txhob raug khawb, folds, tawg, xeb, nplai, qhov, pitting thiab lwm yam tsis xws luag.
6.Qhov tag nrho thickness ntawm decarburization txheej nyob rau hauv lub vojvoog kev taw qhia ntawm cov khoom siv txias txias yuav tsum tsis pub tshaj 1-1.5% ntawm txoj kab uas hla ntawm cov khoom siv raw (qhov xwm txheej tshwj xeeb yog nyob ntawm txhua qhov chaw tsim khoom).
7.In thiaj li yuav xyuas kom meej qhov zoo ntawm txias forming txiav tawm, txias txias cov ntaub ntawv uas yuav tsum tau ib tug nyuaj nto, tab sis lub plawv yog mos.
8. Cov khoom siv kos duab txias yuav tsum tau nqa tawm qhov kev ntsuas txias txias, tib lub sijhawm, cov khoom siv yuav tsum tsis tshua muaj rhiab rau txias hardening, thiaj li yuav txo tau cov txheej txheem deformation, vim txias hardening deformation kuj nce.
