Kev kho cua sov yog ib qho cuab yeej siv los txhim kho lub zog, hardness, thiab durability ntawm shank adapters. Cov txheej txheem kev kho cua sov yuav tsum ua kom sov cov khoom mus rau qhov kub thiab txias thiab tom qab ntawd ua kom txias hauv qhov kev tswj hwm.
Lub hom phiaj tseem ceeb ntawm kev kho cua sov ntawm lubShank Adaptersyog tiv thaiv lub shank los ntawm piling thiab collapsing raws li ib tug tshwm sim ntawm lub piston lub high-frequency cuam tshuam. Shank Adapters's HRC 50-54 hardness yuav ua tau raws li cov lus qhia saum toj no rau 55SiMnMo steel. Qhov kub yuav tsum tau ua kom sov kho 55SiMnMo steel yog 870 degree 20 degree. Nws raug nquahu kom siv qhov nruab nrab zaus induction coil rhaub nrog lub cua sov ntev ntawm 70-80 mm thiab quench hardness ntawm HRC56-58.
Tempering ntawmShank Adapters320-340 degree ntxiv rau 10 degree. HRC52-54 yog hardness tom qab tempering. Lub tshuab hluav taws xob batch cov tshuaj pleev ib ce muaj cov pa roj carbon ntau (tuaj yeem pom los ntawm kev lees paub zoo). Yog tias cov ntsiab lus carbon tsawg, qhov ntsuas kub qis yuav tsum tau siv; txwv tsis pub, qhov kub thiab txias yuav tsum siab. Hloov pauv, nce qhov kub thiab txias dua yog tias Shank Adapters lub hardness ntau dua HRC54 tom qab tempering. Thaum normalizing Shank Adapters, qhov kub thiab txias yuav tsum qis dua qhov pib tempering yog tias qhov hardness tom qab tempering tsawg dua HRC48.
Kev siv tshwj xeeb uas tsis tshua muaj kub ntsev rauv yog qhia rau ib nrab tempering ntawm Shank Adapters; Qhov ntev ntawm lub immersion ntsev tank yuav tsum tsis txhob tshaj lub khob hliav qab lub xub pwg nyom, uas yog 10 mm tob tshaj lub quenching ntev.
Lub hom phiaj ntawm kev kho cua sov:
Hardening: Lub hom phiaj tseem ceeb ntawm kev kho cua sov yog ua kom lub zog ntawm lub shank adapter, ua rau nws tiv taus hnav thiab deformation thaum lub sijhawm ua haujlwm drilling.
Structure Transformation:Kev kho cua sov hloov cov microstructure ntawm cov khoom, txhim kho nws cov khoom siv kho tshuab thiab kev ua haujlwm tag nrho.
Kev Tiv Thaiv Kev Nyuaj Siab: Cov txheej txheem kev kho cua sov pab txo cov kev ntxhov siab sab hauv uas tuaj yeem tsim thaum lub sijhawm tsim khoom lossis kev ua haujlwm dhau los, txo qhov kev pheej hmoo ntawm kev tawg lossis tsis ua haujlwm.
Hom kev kho cua sov:
quenching: Kuj hu ua hardening, txheej txheem no yuav tsum tau cua sov lub shank adapter rau ib tug tshwj xeeb kub (sab saum toj no nws tseem ceeb kub) thiab ces sai txias nws, feem ntau nyob rau hauv ib tug quenching nruab nrab xws li roj los yog dej. Qhov txias txias no "freezes" cov khoom siv microstructure, ua rau muaj zog ntxiv.
Tempering:Tom qab quenching, shank adapter feem ntau yog tempered los txo nws cov brittleness thiab txhim kho nws toughness. Cov txheej txheem no suav nrog rov ua kom cov khoom tawv tawv kom qis dua thiab tom qab ntawd maj mam txias. Tempering pab sib npaug ntawm hardness thiab toughness ntawm lub adapter, kom ntseeg tau tias nws muaj peev xwm tiv taus kev cuam tshuam thiab tiv thaiv tawg.
Kev kho cua sov Parameters:
Kub: Cov txheej txheem kev kho cua sov yuav tsum muaj kev tswj xyuas qhov kub ntawm cov cua sov, uas txawv nyob ntawm seb cov khoom tshwj xeeb thiab qhov xav tau hardness qib.
Lub sij hawm tuav:Cov khoom yog tuav ntawm lub hom phiaj kub rau ib lub sij hawm tshwj xeeb kom ntseeg tau tias cov cua sov tsis sib xws thiab tso cai rau kev hloov pauv ntawm cov qauv xav tau.
Txias tus nqi:Cov cua txias thaum lub sij hawm quenching yog qhov tseem ceeb kom ua tiav qhov xav tau hardness. Kev ua kom txias sai, raws li muab los ntawm quenching nruab nrab, pab tsim microstructure hardened.
Kev Tswj Xyuas Zoo:
Saib xyuas:Thoob plaws hauv cov txheej txheem kev kho cua sov, qhov kub thiab lub sij hawm raug soj ntsuam xyuas kom zoo sib xws thiab ua raws li cov txheej txheem teev tseg.
Kev kuaj:Tom qab kev kho cua sov, shank adapters yuav raug kuaj ntau yam, xws li kev sim hardness, los xyuas qhov ua tau zoo ntawm cov txheej txheem thiab xyuas kom meej qhov xav tau hardness theem tau tiav.
