Manufacturing txheej txheem ntawm Railway Bolts
Kev tsim cov txheej txheem ntawm kev tsheb ciav hlau bolts suav nrog ntau cov kauj ruam tseem ceeb los xyuas kom meej tias cov khoom siv tau zoo thiab txhim khu kev qha rau kev siv tsheb ciav hlau. Ntawm no yog ib tug txheej txheem cej luam ntawm cov txheej txheem raug raug rau railway bolts:
Kev xaiv khoom
Cov txheej txheem pib nrog kev ua tib zoo xaiv cov khoom siv. Cov khoom siv feem ntau muaj xws li carbon steel, alloy steel, stainless hlau, lossis lwm yam ntaub ntawv raws li cov kev cai tshwj xeeb ntawm daim ntawv thov.
Txiav thiab sib sau
Cov ntaub ntawv nyoos raug txiav rau hauv qhov ntev kom tsim nyog, thiab thawj daim ntawv ntawm lub bolt yog tsim. Qhov no yuav koom nrog cov txheej txheem txias los yog kub forging los tsim cov ntsia liaj qhov rooj blanks.
Lub taub hau
Lub taub hau ntawm lub ntsia liaj qhov rooj yog tsim los ntawm cov txheej txheem hu ua heading. Qhov no suav nrog kev tso lub ntsia liaj qhov rooj rau hauv lub tshuab taub hau, qhov twg lub taub hau zoo li nyob rau hauv siab thiab kub.
Xov Rolling
Cov xov yog tsim rau ntawm lub shank ntawm lub bolt los ntawm txoj kev hu ua xov dov. Qhov no yog txheej txheem txias-forming uas ua rau kom lub zog thiab durability ntawm threads.
Kev kho cua sov
Cov bolts tuaj yeem dhau los ua cov txheej txheem kho cua sov xws li quenching thiab tempering los txhim kho lawv cov khoom siv kho tshuab, suav nrog hardness thiab toughness.
Nto Txheej
Bolts tej zaum yuav coated nrog cov ntaub ntawv tiv thaiv los txhim kho corrosion kuj. Cov txheej txheem muaj xws li kub-dipped galvanization, zinc plating, los yog lwm yam corrosion-resistant coatings.
Kev Tswj Xyuas Zoo
Kev tswj xyuas nruj nruj yog siv thoob plaws hauv kev tsim khoom. Qhov no suav nrog kev tshuaj xyuas qhov ntev, threading zoo, thiab cov khoom siv.
