Manufacturing txheej txheem ntawm bolts
1.Spheroidizing annealing ntawm high-strength bolts
Thaum lub hexagon socket lub taub hau bolts yog tsim los ntawm cov txheej txheem txias taub hau, cov qauv qub ntawm cov hlau yuav ncaj qha cuam tshuam rau kev tsim muaj peev xwm thaum lub caij txias ua haujlwm. Yog li ntawd, cov hlau yuav tsum muaj plasticity zoo. Thaum cov tshuaj muaj pes tsawg leeg ntawm cov hlau tsis tu ncua, cov qauv metallographic yog qhov tseem ceeb ntawm kev txiav txim siab plasticity. Nws feem ntau ntseeg hais tias cov ntxhib flaky pearlite tsis haum rau kev sib sau txias, thaum lub ntsej muag zoo nkauj pearlite tuaj yeem txhim kho lub peev xwm ntawm cov yas deformation ntawm cov hlau.
Rau nruab nrab carbon steel thiab nruab nrab carbon alloy steel nrog ib tug loj npaum li cas ntawm cov high-strength fasteners, spheroidizing annealing yog ua ua ntej txias taub hau, thiaj li yuav tau uniform thiab nplua spheroidized pearlite kom zoo dua raws li qhov tseeb ntau lawm.
2.high-strength bolt daim duab
Lub hom phiaj ntawm cov txheej txheem kev kos duab yog los hloov qhov loj ntawm cov ntaub ntawv raw, thiab qhov thib ob yog kom tau txais cov cuab yeej siv tshuab yooj yim ntawm lub fastener los ntawm deformation thiab ntxiv dag zog. Yog tias qhov kev faib tawm ntawm qhov txo qis ntawm txhua qhov dhau los tsis tsim nyog, nws tseem yuav ua rau cov kab nrib pleb tawg hauv cov hlua hlau xaim thaum lub sij hawm kos duab. Tsis tas li ntawd, yog hais tias lub lubrication tsis zoo thaum lub sij hawm kev kos duab, nws kuj tuaj yeem ua rau cov kab nrib pleb tsis tu ncua hauv qhov txias rub hlau pas nrig. Lub tangent kev taw qhia ntawm cov hlau pas nrig thiab hlau kos duab tuag tib lub sij hawm thaum lub hlau pas nrig yog dov tawm ntawm lub pellet hlau tuag lub qhov ncauj tsis concentric, uas yuav ua rau lub hnav ntawm lub unilateral qhov qauv ntawm cov hlau drawing tuag rau aggravate. , thiab lub puab lub qhov yuav tawm ntawm puag ncig, uas ua rau tsis sib npaug ntawm daim duab deformation nyob rau hauv lub circumferential kev taw qhia ntawm cov hlau, ua rau lub roundness yog tsis kam, thiab cov cross-sectional kev nyuaj siab ntawm steel hlau tsis zoo li thaum lub caij txias. txheej txheem taub hau, uas cuam tshuam rau qhov txias taub hau hla tus nqi.
Qhov zoo ntawm lub log hub bolts
1. Kev tsim khoom nruj: siv cov khoom siv raw uas ua tau raws li lub teb chaws tus qauv, thiab nruj me ntsis ua raws li cov qauv kev xav tau ntawm kev lag luam
2. Kev ua tau zoo heev: ntau xyoo ntawm kev paub hauv kev lag luam, qhov chaw ntawm cov khoom yog du, tsis muaj burrs, thiab lub zog sib xws
3. Cov xov yog qhov tseeb: cov khoom xov yog qhov tseeb, cov hniav ntsia hlau zoo huv si, thiab kev siv tsis yooj yim rau plam
