Qhov kev xav tau tshaj plaws ntawm kev tsim kho cov fasteners hauv 2024

Hauv cov ntawv thov, cov fasteners yuav muaj cov teeb meem zoo rau ntau yam laj thawj, uas yuav yooj yim ua rau cov xwm txheej yooj yim, lossis ua rau kev puas tsuaj rau cov tshuab lossis engineering, cuam tshuam tag nrho cov kev ua tau zoo tag nrho. Cov teeb meem saum npoo yog ib qho teeb meem zoo ntawm cov fasteners, uas tuaj yeem ua rau muaj ntau hom ntawv xws li cov kab nrib pleb, dents, txiav, puas, thiab lwm yam.

Yuav ua li cas thiaj txiav txim siab qhov zoo ntawm lub fasteners los ntawm saum npoo?

Nws tuaj yeem raug txiav txim los ntawm cov kab nrib pleb ntawm lub rooj nrawm. Muaj ntau hom nrib pleb ntawm cov npoo nrawm, uas feem ntau yog tshwm sim los ntawm kev sib txawv. Quenching cov kab nrib pleb yog tshwm sim los ntawm kev ntxhov siab ntau dhau ntawm cov kev ntxhov siab ntau zaus thaum lub sijhawm kho kom sov, thiab kev lom zem thaum lub sijhawm txiav lossis cov txheej txheem forging. Forging cracks and shearing cracks may also cause defects such as forging bursts and shearing bursts during the forging process.

Dents yog tshwm sim los ntawm cov chips lossis shear burrs lossis rust txheej txheej ntawm cov khoom nyoos. Yog tias lawv tsis tau tshem tawm thaum lub sijhawm zam txim lossis cov txheej txheem chim siab, lawv yuav nyob rau saum npoo ntawm lub khawm khawm. Tsis yog tsuas yog thaum ua cov txheej txheem kev ua tiav, qhov tsis raug rau tus cwj pwm tsis raug rau lwm qhov txuas ntxiv, tuaj yeem yooj yim rau kev thauj mus los los ntawm lwm cov khoom siv sab nraud thiab ua rau cov qev sab nraud thiab ua rau duav, khawb, thiab tsis yog pov tseg.

Dab tsi yog cov phom sij yog tias lub nrawm nrawm tsis tau raws cov qauv?

Tsis muaj txiaj ntsig ceev cov muaj peev xwm, hnav, deformation, cov khoom tsis muaj peev xwm thiab lwm yam teeb meem tuaj yeem poob tawm, muaj kev cuam tshuam txog kev nyab xeeb lossis kev ua haujlwm encanger. Ib qho ntxiv, vim muaj kev cuam tshuam ntawm ib puag ncig ntawm cov fasteners, yog tias qhov zoo tsis tau raws li cov qauv, xeb, qaug zog ua kom tsis muaj zog.
