Cov txheej txheem thiab kev xav tau rau kev tsim cov bolts muaj zog

1. Kev xaiv cov khoom siv
Cov pa roj carbon steel muaj kev ua haujlwm zoo heev, tuaj yeem ua tau raws li ntau yam kev sib txuas ua haujlwm, thiab muaj tus nqi qis dua piv rau lwm cov ntaub ntawv fastener.
Cov khoom siv hluav taws xob ntawm cov hlau yog qhov nkag siab rau cov ntsiab lus carbon, uas feem ntau yog qis dua 1.0%. Peb feem ntau paub qhov txawv ntawm cov pa roj carbon tsawg (C% ≤ 0.25%), nruab nrab carbon steel (0.25% 0.45%), thiab hlau alloy (ntxiv cov ntsiab lus alloying rau cov pa roj carbon zoo tib yam) raws li cov ntsiab lus carbon hauv cov khoom siv hlau.
2. Spheroidization (softening) annealing
(1) Thaum spheroidized (softened) annealed countersunk taub hau screws thiab hexagonal cylindrical lub taub hau bolts yog tsim los ntawm kev siv lub taub hau txias, cov qauv qub ntawm cov hlau ncaj qha cuam tshuam rau kev tsim muaj peev xwm thaum lub caij txias ua haujlwm. Thaum lub caij txias txias, cov yas deformation hauv cheeb tsam tuaj yeem ncav cuag 60% -80%. Yog li ntawd, nws yuav tsum tau hais tias cov hlau yuav tsum muaj zoo plasticity.
(2) Rau nruab nrab carbon steel thiab nruab nrab carbon alloy steel nrog ib tug loj npaum li cas ntawmhigh-zog fasteners, spheroidization (softening) annealing yuav tsum tau nqa tawm ua ntej lub taub hau txias kom tau txais cov khaub ncaws zoo thiab zoo spheroidized pearlite, txhawm rau kom ua tau raws li cov kev xav tau ntau lawm.
3. Hlau kos duab
Nthuav lub disc thiab siv qhov sib thooj rub lub zog rau nws kom ua tiav qhov yuav tsum tau xaim kab (piv txwv li txoj kab uas hla) rau kev tsim khoom.
Txoj kab uas hla ntawm cov hlau ruaj khov rau cov phaj loj hauv cov hlau mills suav nrog M8, M10, M12, M16, thiab lwm yam. Lawv tsis tuaj yeem siv ncaj qha rau kev tsim cov ntsia liaj qhov rooj. Piv txwv li, ua 10 hli txoj kab uas hla tag nrho threaded ntsia liaj qhov rooj yuav tsum rub lub txoj kab uas hla ntawm lub disc mus rau 8.78 + 0.04 hli, thaum tsim ib tug 16 hli txoj kab uas hla bolt yuav tsum tau ib tug hlau txoj kab uas hla ntawm 14.38 + 0.02 hli.
4.Txias forging
Kev tsim ntawm lub hex lujlub taub hau adopts txias forging yas ua. Piv nrog rau kev txiav, cov hlau fiber ntau (hlau hlau) txuas ntxiv raws cov khoom zoo li tsis muaj kev txiav hauv nruab nrab, yog li txhim kho cov khoom siv zog thiab tau txais cov khoom zoo heev. Cov txheej txheem txias taub hau muaj xws li txiav thiab tsim, ib qho chaw nres tsheb ib zaug nias, ob npaug nias lub taub hau txias, thiab ntau qhov chaw nres tsheb tsis siv neeg txias.
6. Xov xov ua haujlwm
Bolt threads feem ntau ua tiav los ntawm kev ua haujlwm txias, nyob rau hauv uas xov blanks nyob rau hauv ib txoj kab uas hla yog rubbed (dov) los ntawm ib tug ntsia hlau phaj (tuag), thiab threads yog tsim los ntawm lub siab ntawm cov ntsia hlau phaj (dov tuag). Cov yas streamline ntawm threaded ib feem tuaj yeem tau txais yam tsis raug txiav, ua rau muaj zog ntxiv, siab precision, thiab cov khoom zoo sib xws, uas yog siv dav.
Qhov zoo tshaj plaws ntawm dov (rubbing) xov ua yog tias lub dov ceev tsis tas yuav siab dhau. Yog tias nws siab dhau lawm, qhov ua tau zoo yog qhov tsawg thiab qhov chaw ntawm cov hniav ntawm cov hniav yog qhov yooj yim rau kev sib cais los yog tsis sib xws threading. Ntawm qhov tsis sib xws, yog tias tus naj npawb ntawm cov kiv puag ncig tsawg dhau, cov xov kab kab uas hla yog qhov ua rau poob qis, thiab qhov pib siab thaum dov nce txawv txav, ua rau lub neej luv luv.
7. Kev kho cua sov
Kub khohigh-zog fastenersyuav tsum tau quenching thiab tempering kev kho mob raws li cov kev xav tau los txhim kho cov khoom siv kho kom zoo ntawm cov fasteners thiab ua tau raws li qhov ntsuas tensile lub zog thiab cov txiaj ntsig ntawm cov khoom.
Vim tias qhov ntim ntau lawm thiab tus nqi qis ntawm cov bolts muaj zog, nrog rau cov qauv tsim nyog thiab cov qauv ntawm cov xov, nws yuav tsum muaj cov khoom siv kho cua sov yuav tsum muaj kev sib raug zoo ntau lawm, qib siab ntawm automation, thiab kev kho cua sov zoo. Txhawm rau tsim cov khoom siv hluav taws xob zoo siab, cov cuab yeej siv hluav taws xob siab tshaj plaws yog qhov tseem ceeb.
