Cold Heading Forming Txheej Txheem Rau Steel Structure Bolts

Steel qauv bolts yog hlau yas-forming fasteners. Lawv cov txheej txheem tsim khoom muaj ntau cov txheej txheem meej thiab sib cuam tshuam, txhua qhov ncaj qha txiav txim siab qhov tseeb qhov tseeb, cov khoom siv kho tshuab thiab ua tiav zoo ntawm cov bolts. Lub taub hau txias txoj kev ua haujlwm yog cov txheej txheem tseem ceeb ntawm kev tsim cov ntsia liaj qhov rooj thiab ua lub luag haujlwm txiav txim siab hauv lub zog tag nrho thiab kev ruaj ntseg ntawm cov qauv steel bolts.

Cov txheej txheem ua tiav ntawm cov qauv steel bolts yog raws li hauv qab no: kos duab txias → spheroidizing annealing → mechanical dephosphorization → pickling thiab fine tu → Secondary precision drawing → txias heading forming → thread processing → heat treatment → tiav cov khoom soj ntsuam. Tag nrho cov txheej txheem yog qhov tseem ceeb thiab yuav tsum tau ua raws li nruj raws li tus qauv specifications los lav qhov zoo ntawm high-strength steel qauv bolts.

Nyob rau hauv txoj kev bolt txoj kev, ntsia liaj qhov rooj hau yog tsuas yog tsim los ntawm txias hau yas forming, thaum tsuas yog ib tug me me ntawmtshwj xeeb boltstxais yuav kev txiav. Piv nrog rau cov txheej txheem txiav ib txwm, lub taub hau txias tsis cuam tshuam cov hlau fiber ntau. Nws ua kom txuas ntxiv thiab ua tiav cov hlau streamlines faib raws cov ntsia hlau profile yam tsis muaj kev puas tsuaj los yog truncation defects. Cov txheej txheem tsim no zoo heev txhim kho tag nrho lub zog, toughness thiab qaug zog tsis kam ntawm bolts, ua rau cov khoom siv dav dav ntawm lub taub hau txias-headed steel qauv bolts zoo dua li cov txiav bolts.

Cov txheej txheem txias taub hau feem ntau suav nrog kev txiav cov khoom, pre-forming thiab kawg sib sau. Nws tuaj yeem muab faib ua peb hom khoom siv: ib leeg-stroke ib leeg-chaw nres tsheb txias taub hau, ob-stroke ib leeg-chaw txias taub hau, thiab ntau lub chaw nres tsheb tsis siv neeg txias. Multi-chaw nres tsheb tsis siv neeg txias taub hau tshuab tuaj yeem ua tiav stamping, chim siab, extrusion, txoj kab uas hla txo thiab lwm cov txheej txheem tsim hauv ntau cov pwm. Featuring siab ua tau zoo thiab cov khoom zoo sib xws, lawv yog cov khoom siv tseem ceeb rau cov qauv steel hlau bolts.

Ib-chaw nres tsheb lossis ntau lub chaw nres tsheb txias cov khoom siv tuaj yeem xaiv tau raws li cov khoom tshwj xeeb. Cov txheej txheem kev ua haujlwm thiab cov txheej txheem tsim tsis muaj nyob ntawm cov ntaub ntawv raw khoom, suav nrog cov ntaub ntawv ncaj nraim nrog qhov ntev ntawm 5 mus rau 6 meters thiab loj coil hlau rods nrog qhov hnyav ntawm 1900 txog 2000 kilograms.

Lub ntsiab feature ntawm cov txheej txheem txias taub hau rausteel qauv boltsyog tias prefabricated ib-thooj blanks tsis tas yuav tsum tau. Cov cuab yeej siv tau ncaj qha ua qhov ntev-ntev txiav, tsis siv neeg chim siab thiab ua ib kauj ruam ntawm cov ntaub ntawv bar thiab xaim rods kom ua tiav bolt dawb paug ua hauv ib lub voj voog, xa cov khoom ua haujlwm siab thiab ruaj khov tsis muaj tseeb.

Raws li cov txheej txheem tseem ceeb hauv kev tsim cov ntsia liaj qhov rooj, lub taub hau txias txiav txim siab qhov kev ua tau zoo ntawm cov khoom siv, cov qauv raug thiab kev pabcuam lub neej ntawm steel qauv bolts. Yog li ntawd, kev tswj xyuas nruj yuav tsum tau ua raws li cov txheej txheem txias ntawm cov txheej txheem, cov khoom siv raws li txoj cai thiab tsim cov khoom zoo thaum lub sijhawm tsim khoom. Txhua qhov kev ua tiav yuav tsum raug tswj xyuas kom meej kom ntseeg tau tias cov bolts tiav ua tau raws li qhov yuav tsum tau muaj zog thiab ruaj khov ntawm steel qauv engineering daim ntawv thov.
