Cov ntawv xov xwm crankshaft (nrog rau cov ntawv xov xwm tseem ceeb thiab cov ntawv xov xwm txuas txuas) yog cov khoom tseem ceeb rau kev xa cov cav fais fab. Raws li cov kev cai ntawm lub teb chaws tus qauv GB / T 24595-2020, lub hardness ntawm steel tuav siv rau crankshafts yuav tsum nruj me ntsis tswj tom qab quenching thiab tempering. Cov kev lag luam hauv tsev thiab thoob ntiaj teb kev lag luam tsheb muaj cov qauv tsim nyog rau qhov hardness ntawm crankshaft cov ntawv xov xwm, thiab kev ntsuam xyuas hardness yog cov txheej txheem tseem ceeb ua ntej cov khoom tawm hauv lub hoobkas.
Raws li GB / T 24595-2020 Steel Bars rau Tsheb Crankshafts thiab Camshafts, lub hardness ntawm crankshaft cov ntaub ntawv yuav tsum tau raws li qhov yuav tsum tau ntawm HB 220-280 tom qab quenching thiab tempering.
Tus qauv ASTM A1085 (tso tawm los ntawm American Society for Testing and Materials, ASTM) qhia tias qhov nyuaj ntawm kev sib txuas cov ntawv xov xwm rau cov neeg caij tsheb crankshafts yuav tsum yog ≥ HRC 28 (xws li HB 270).
Txawm hais tias los ntawm qhov kev xav ntawm kev tsim khoom hauv kev zam cov nqi rov ua haujlwm thiab kev tiv thaiv lub koob npe nrov, cov neeg siv sab hauv kev tiv thaiv kev siv lub tshuab ua haujlwm luv luv thiab tsis ua haujlwm txaus ntshai, lossis tom qab kev muag khoom hauv kev zam kev nyab xeeb, nws yog ib qho tseem ceeb kom txwv tsis pub cov khoom lag luam tsis zoo nkag mus rau hauv kev ua lag luam thiab ua cov crankshaft hardness kuaj nruj raws li cov qauv.
Rockwell hardness tester tshwj xeeb rau crankshafts uas tsim los ntawm peb lub tuam txhab paub tag nrho automated functions xws li lub zog ntawm lub crankshaft workbench, kuaj, thiab cov ntaub ntawv kis tau tus mob. Nws tuaj yeem ua tau sai li Rockwell hardness tests (xws li, HRC) ntawm cov txheej txheem hardened ntawm ntau qhov chaw ntawm crankshaft.
Nws siv lub kaw lus kaw hluav taws xob rau kev thauj khoom thiab kev sim, qhov ntsuas no tau ua tiav tag nrho nrog ib lub pob (txog mus rau qhov chaw ua haujlwm, thov kev thauj khoom, tswj kev thauj khoom, nyeem ntawv, thiab tso cov khoom ua haujlwm tag nrho ua tiav, tshem tawm tib neeg yuam kev).
Lub crankshaft clamping system muaj qhov tsis siv neeg thiab phau ntawv txav mus rau pem hauv ntej thiab rov qab, nrog rau xaiv sab laug, sab xis, thiab nce thiab nqis, tso cai ntsuas ntawm txhua qhov chaw crankshaft.
Ib qho kev xaiv crankshaft txoj hauj lwm ntsuas phoo muab kev yooj yim rau tus kheej xauv, tshem tawm qhov kev pheej hmoo ntawm workpiece slippage thaum ntsuas.
