Caij Nplooj Hlav Hlau Hlau

Caij Nplooj Hlav Hlau Hlau

Caij nplooj ntoos hlau hlau hlau yog hom ntawm cov hlau xaim siv los ua rau lub cav (caij nplooj ntoo hlav) lossis cov ntawv xaim (xaim daim ntawv). Raws li kev siv sib txawv ntawm kev siv hluav taws xob hlau, muaj ntau hom hluav taws xob hlau, thiab cov xov hluav taws xob rau kev ncua cov xov hlau, thiab hluav taws xob hlau Cov xov hluav taws xob steel dej kuj tseem tuaj yeem ua raws li cov xov hluav taws xob steel hlau, cov roj Qwj lub zog ntawm lub caij nplooj ntoo hlav raj hluav taws xob steel hlau yuav muaj nyob rau hauv thaj tsam ntawm 1000-3000 MPa. Lub cheeb ntawm round caij nplooj ntoos hlav steel hlau xov tooj los ntawm 0.08 mus rau 20 hli. Tus ntoo khaub lig-seem ntawm lub caij nplooj ntoos hlav steel hlau feem ntau yuav muaj cov hlau xaim hluav taws xob feem ntau xa hauv yob, tab sis nws tseem tuaj yeem xa hauv cov kab ncaj.

Springs siv nyob rau hauv cov chaw sib txawv muaj cov kev tshwj xeeb tshwj xeeb rau cov hlau hlau. Piv txwv li: Springs ua haujlwm hauv corrosive med xav tau zoo corrosion tsis kam; Springs nyob rau hauv cov kev seev ceev xav tau kev ruaj khov ntev thiab rhiab; Springs nyob rau hauv siab-kub ib puag ncig yuav tsum muaj kev txwv ywj thiab cov plhuav ntxiv.
Hlau hlau rau kev tsim cov springs ntawm ntau hom thiab siv.
Cov hom tseem ceeb yog:
(1) Tus Hlau Hlau Rau Cov Khaub Ncaws Txias-Rolled. Cov caij nplooj ntoos hlav no tsis kub-kho tom qab txias-dov lossis tsuas yog siv tom qab cua sov tsawg. Nws yog tsuas yog carbon caij nplooj ntoos hlav steel hlau hlau;
(2) Lub Caij Nplooj Hlav Hlau Hlau Hlau uas yog cov cua sov-kho tom qab winding. Nws yog tsuas yog Alloy Caij Nplooj Hlav Hlau Hlau Hlau;
(3) quenyed thiab tempered caij nplooj ntoos hlav steel hlau, tseem hu ua roj quenched thiab tempered caij nplooj ntoos hlav steel hlau;
(4) Stainless Caij Nplooj Hlav Hlau Hlau Hlau. Hom ntawm steel hlau feem ntau yog ua los ntawm Austenitic Stainless hlau. Nws cov yam ntxwv ntau heev tau qhia hauv Almloy Steel hlau. Tsis tas li ntawd, kuj tseem muaj deformation kub-kho cov hlau xaim hauv kev loj hlob.

Carbon caij nplooj ntoos hlav steel hlau yuav tsum muaj lub zog tensile muaj zog, elastic txwv, muaj kev txwv thiab qaug zog rau kev cuam tshuam thiab kev co. Ua kom muaj zog thiab kev ntsuas nruj, tiv thaiv kev tiv thaiv cov kab nrib pleb, yog tus yuam sij rau kev tsim hluav taws xob hlau hlau. Cov tsis zoo thiab qhov zoo ntawm cov nqaj hlau ncaj qha cuam tshuam rau kev ua haujlwm ntawm cov hlau. Carbon Caij Nplooj Ntoos Hlav Hlau Hlau yog ua los ntawm High-Carbon High-Tool Cov Hlau Hlau lossis Cov Khoom Siv Roj Hlau Thiab Cov Khaub Ncaws Roj Thiab Cov Khoom Uas Tsis Muaj Peev Xwm Tswj Raws Li Lub Caij Nplooj Ntoos Hlav. Txhawm rau kom txo cov txheej txheem sab nraud thiab cov txheej txheem decarburization, cov hlau billet rau cov pas nrig hlau yuav tsum yog av hauv av thiab tev yog tsim nyog. Yuav tsum yog cov pas nrig hlau hlau yuav tsum yog qhov ua kom zoo lossis sulphurized, thiab cov lus qhia loj yuav tsum tau hloov los ntawm kev siv hluav taws xob sib xyaw. Soldering kev kho yog dav siv hauv kev kho cua sov kom sov, tshwj xeeb tshaj yog ua ntej kev kos duab ntawm cov khoom tiav. Decarburization yuav tsum tiv thaiv thaum kho cua sov. Tom qab kev kho cua sov, sulfuric acid lossis hydrochloric acid pickling yog siv los tshem tawm cov hlau oxide nplai. Txheej (saib lubricating cabrier) tuaj yeem yog txiv qaub dipped, phosphating, kev kho borax lossis tooj liab plating. Cov txheej txheem kos duab ntawm cov khoom tiav lawm kos duab muaj qhov cuam tshuam zoo ntawm cov khoom ua haujlwm. Feem ntau, txo tus nqi txo ntau ntawm li 90% (saib cov feem ntau txo tus feem pua ​​txo tus nqi (li ntawm ≤23%) tau siv los xyuas kom meej ntawm cov khoom. Rau siab-zog caij nplooj ntoos hlav steel hlau xaim, qhov hluav taws xob qhov hluav taws xob ntawm txhua qhov kev kos duab hauv qab no 150 ℃ Thaum lub ntsiab qhov tsis xws luag uas ua rau cov hlau xaim kom tawg. Vim li no, cov khoom siv lubrication zoo thiab txias yuav tsum tau muab rau thaum lub sijhawm kos duab. Tus nqi txo qis dua thiab kos duab kev kos duab tuaj yeem pab txo qhov kub ntawm cov hlau xaim. Tom qab kos duab, muaj ntau qhov kev ntxhov siab loj hauv cov hlau xaim, uas cuam tshuam nws cov kev ua tau zoo. Nws tuaj yeem tshem tawm los ntawm online ncaj lossis tsawg-kub (180-370 ℃) cua sov.
Alloy Caij Nplooj Hlav Hlau Hlau yog ua los ntawm alloy caij nplooj ntoos hlav stomon Decarburization yuav tsum tau tiv thaiv thaum kho cua sov, thiab nag lossis daus ntawm cov pa roj carbon monoxide kuj tseem yuav tsum tau tiv thaiv kom tsis txhob muaj cov pas dej caij nplooj ntoos hlav. Recrystallization annealing yog siv rau kev kho cua sov ntawm cov khoom tiav ntawm ib nrab. Tus xaiv thiab txheej txheej txheem ua tau zoo ib yam li cov khoom lag luam rau cov carbon choj tsuag steel hlau. Raws li cov kev xav tau, silicon mirmanese caij nplooj ntoos hlav steel hlau muaj cov kev kos duab txias xws li kev ua kom txias, cov nyiaj kub thiab roj quenching; Chrome Vanadium Caij Nplooj Ntoos Hlav Hlau Hlau Muaj cov lus txawv txawv xws li mob khaub thuas, annealing, nyiaj ci. Feem ntau, alloy caij nplooj ntoos hlau hlau yuav tsum yog quenched thiab tempered ntawm nruab nrab kub ua ntej nws tuaj yeem siv tom qab raug mob rau hauv dej txhawv.
Lub Caij Nplooj Hlav Hlav Hlau Hlau feem ntau suav nrog cov roj quenching-temping carbon caij nplooj ntoos hlav steel hlau xaim hlau xaim xaim hlau rau li qub. Lub hom phiaj ntawm cov roj quenching-temping quenching thiab tempering tom qab caij nplooj ntoos hlav steel hlau muaj ntau dua li kev ua kom zoo thiab nkees ua yeeb yam. Springs ua los ntawm quenched steel xaim hlau muaj ruaj khov geometric
