Cov txheej txheem tseem ceeb ntawm Bolt Manufacturing

Hauv kev tsim khoom ntawmbolts, txheej txheem technology yog ib feem tseem ceeb heev. Yog tias cov txheej txheem fastener bolt txheej txheem hloov pauv, nws yuav cuam tshuam rau kev tsim khoom zoo ntawm bolts. Kev tsim cov txheej txheem ntawm bolts feem ntau yog raws li nram no: disk - straightening - annealing - stripping oxidation - pier taub hau - kho cua sov - dov xov - nto kho - lubrication - ntim. Hauv qab no yog ib qho kev ntsuam xyuas ntawm cov txheej txheem tseem ceeb.

Ⅰ. Txias taub hau

Lub taub hau txias (extrusion) tshuab yog lub tshuab ua haujlwm tseem ceeb, koom nrog hauv qeb ntawm cov hlau siab ua haujlwm hauv kev tsim khoom, ntawm qhov kub thiab txias, cov hlau ua rau sab nraud quab yuam, kom cov hlau nyob rau hauv predetermined pwm tsim, hom no feem ntau hu ua txias. nqe lus. Qhov tseeb, txoj kev tsim cov fastener tsis yog tsuas yog ib qho kev deformation ntawm lub taub hau txias, tab sis kuj muaj ntau txoj kev deformation xws li pem hauv ntej thiab thim rov qab extrusion, composite extrusion, xuas nrig ntaus, txiav thiab dov. Qhov zoo ntawm lub taub hau txias yog: kev siv tus nqi siab ntawm cov hlau, cov khoom tsim tau zoo, cov khoom siv kho tshuab zoo, haum rau kev tsim khoom tsis siv neeg, tsim rau ntau lawm.

Ⅱ. Kev kho cua sov

Raws li cov cuab yeej cuab tam ntawm bolts, lawv tau muab faib ua cov bolts uas muaj zog thiab zoo tib yam bolts. High-strength bolts feem ntau xa mus rau bolts nrog txhua yam khoom qib siab dua lossis sib npaug rau 8.8. Cov khoom no feem ntau yog ua los ntawm cov pa roj carbon tsawg thiab nruab nrab (xws li boron lossis manganese lossis chromium) steel lossis cov khoom siv zoo carbon steel tsim, ntxiv rau ntau hom kev qhia tshwj xeeb, yuav tsum tau ua kom tawv thiab tempered, nrog cov khoom siv ntau dua thiab kev ua haujlwm. , feem ntau siv rau siab dua cov kev xav tau ntawm lub sijhawm.

Muaj ntau yam tsis xws luag hauv kev kho cua sov, xws li tsis txaus deg hardness, tsis txaus lub zog tensile, loj deformation, quenching, cracking thiab nto oxidation. Muaj ntau yam cuam tshuam rau qhov tsis xws luag ntawm kev kho cua sov, xws li hardenability ntawm steel cov tshuaj muaj pes tsawg leeg ntawm austenite quenching cua sov kub nruab nrab txias ceev thawj cov qauv workpiece zoo residual kev ntxhov siab thiab nws cov khoom faib cua sov thiab cua.

Ⅲ. Rolled Xov

Ua ntej dov xov, qhov yuav tsum tau dov xov yuav tsum tau tig mus rau cov xov nruab nrab txoj kab uas hla.

Rolling (rubbing) nias xov yog hais txog kev siv cov yas deformation los ua cov xov hniav tsim txoj kev nws yog nrog tib lub suab thiab xov ua xov dov (ntsia hlau phaj) pwm, thaum squeezing cylindrical ntsia hlau billet, thaum ua cov ntsia hlau billet tig, thiab thaum kawg dov pwm ntawm cov hniav hloov mus rau cov ntsia hlau billet, kom cov xov sib sau.

Kev tsis xws luag ntawm dov xov: xov ib feem nto tawg los yog khawb; tsis meej pem buckle. Cov teeb meem no, yog tias lawv tshwm sim hauv cov neeg coob, yuav pom nyob rau hauv cov txheej txheem ua. Yog tias lawv tshwm sim me me, cov txheej txheem ntau lawm tsis pom cov kev tsis zoo no yuav ntws mus rau tus neeg siv, ua rau muaj teeb meem. Yog li ntawd, cov teeb meem tseem ceeb ntawm kev ua haujlwm yuav tsum tau sau tseg, thiab cov ntsiab lus tseem ceeb no yuav tsum tau tswj hwm hauv cov txheej txheem tsim khoom.

Ⅳ. Kev kho saum npoo

Muaj ntau yam khoom siv los ua bolts, xws li carbon steel, alloy steel thiab stainless hlau, tab sis cov khoom siv zoo tshaj plaws thiab kev lag luam yog carbon steel.Carbon steel nws tus kheej tsis muaj peev xwm tiv thaiv corrosion, yog li nws yuav tsum tau kho kom zoo ntawm nws. nto kom tau raws li qhov yuav tsum tau muaj los tiv thaiv corrosion.Different deg txoj kev kho mob muaj ntau yam anti-corrosive qib, thiab cov yam ntxwv ntawm anti-corrosive txheej kuj txawv, kev siv kub ntawm txawv txheej kuj txawv, feem ntau siv bolt nto kho txoj kev yog : hluav taws xob galvanized phosphating electroplating chromium electroplating cadmium, kub dip galvanized, dacro thiab lwm yam.

Cov saum toj no yog kev qhia txog cov txheej txheem tseem ceeb ntawm bolts, vam tias nws tuaj yeem pab tau rau koj. Yog tias koj xav yuav bolts, xaiv hom tsim nyog raws li kev siv tiag tiag, kom tsis txhob poob qhov tsis tsim nyog vim xaiv tsis raug. Yog tias koj xav paub ntau ntxiv txog cov fasteners, koj tuaj yeem ua tib zoo mloog rau Hebei Sinostar.
