Lub luj tshib yog ib qho kev sib txuas ntawm cov yeeb nkab haum hauv cov kav dej, siv rau kev sib txuas cov kav dej ntawm qhov khoov thiab hloov cov kev taw qhia ntawm cov kav dej. Lwm lub npe: 90 degree luj tshib, lub kaum sab xis lub luj tshib, Hlub khoov, stamped luj tshib, nias lub luj tshib, lub luj tshib mechanism, welded luj tshib, thiab lwm yam.
1, Tom qab ntau lawm, cov txheej txheem ua haujlwm rau kev ntxuav lub luj tshib:
1. Raws li qhov yuav tsum tau ua thiab qhov chaw ntawm lub workpiece, alkaline tu, dej-soluble tu neeg ua hauj lwm, chlorine hnyav sandblasting, txhaj tshuaj blasting thiab lwm txoj kev yog siv los ntxuav.
2. Feem ntau, cov kua qaub ntxuav tsis yog siv los ntxuav
2, Khoov kho:
1. Lub workpiece raug kho siv cov khoom zoo li qub, thiab nws feem ntau tsis pom zoo kom tawm tsam hauv zos
2. Tom qab kho, kev ntxhov siab annealing yuav tsum tau nqa tawm ntawm qhov kub qis dua qhov qub tempering kub
3. Austenitic luj tshib workpiece, calibrated ntawm 300 degree C? Ua kev kho kev ntxhov siab hauv qab C
3, Kev tshuaj xyuas zoo ntawm lub luj tshib:
1. Lub workpiece yuav tsum raug tshuaj xyuas raws li cov khoom thiab cov kev cai uas tau teev tseg hauv cov ntaub ntawv qhia txog kev sib raug zoo
2. Thaum cov khoom siv hluav taws xob ntawm cov khoom ua haujlwm tsis tsim nyog, kev kho cua sov tuaj yeem rov ua dua, tab sis tus naj npawb ntawm kev rov ua dua los yog cov khoom siv kho mob feem ntau tsis tshaj ob zaug. Ntxiv tempering ntawm workpieces tsis suav hais tias yog rov ua dua
3. Martensitic luj tshib thiab hnav-resistant luj tshib workpieces nyob rau hauv quenched los yog low-temperature tempered xeev yuav tsum tau preheated, annealed los yog high-temperature tempered ua ntej quenching.
