Muaj ob lub ntsiab ntawm cov khoom siv crankshaft, ib qho yog asteel crankshaftthiab lwm yam yog ductilehlau crankshaft. Cov hlau crankshaft feem ntau yog cov khoom siv hlau uas txiav txim siab qhov zoo ntawm lub crankshaft. Tsis tas li ntawd, kev siv tshuab ua haujlwm thiab kev ua haujlwm raug. Cov hlau crankshaft feem ntau siv cov txheej txheem sib npaug. Qhov tseeb ntawm kev lag luam crankshaft tsis pom ntawm qhov muag liab qab. Ntxiv nrog rau lub kaum sab xis dov txheej txheem, cov hlau hlau crankshaft tseem yuav tsum tau nitrided, thiab xim ntawm nitrided crankshaft yog dub. Thaum xaiv, tsuas yog them sai sai rau kom tsis txhob muaj trachoma, rub cov cim, thiab lwm yam nyob rau hauv lub labyrinth feem, feem ntau yuav tsis muaj teeb meem.

Rough casting technology:

Smelting

Rau cov melting ntawm qib high-qib cam khwb cia hlau, ib tug loj-muaj peev xwm nruab nrab zaus rauv yuav siv tau rau melting los yog ib tug zaus hloov dua siab tshiab intermediate zaus rauv, thiab ib tug ncaj qha nyeem ntawv spectrometer yuav siv tau los xyuas cov molten hlau muaj pes tsawg leeg. Nodular cam khwb cia hlau kev kho mob txais yuav subcontracting los tsim ntau yam tshiab ntawm spheroidizing cov neeg ua hauj, thiab txais yuav advanced inoculation txoj kev xws li incubation, intra-hom inoculation thiab compound inoculation. Cov tsis muaj txheej txheem melting yog tswj los ntawm lub computer thiab tso tawm rau ntawm qhov screen.

Kev ua qauv

Poob ua npuas ncauj casting yuav tsim thiab txhawb nqa. Hauv cov xuab zeb casting, boxless txhaj molding thiab extrusion molding yuav muaj nuj nqis thiab txuas ntxiv mus rau kev txhawb nqa thiab siv hauv cov chaw tsim khoom tshiab lossis rov tsim dua tshiab. Tus thawj high-pressure molding kab yuav txuas ntxiv siv, thiab qee qhov tseem ceeb ntawm cov khoom yuav raug txhim kho kom ua tiav cov tub ntxhais tsis siv neeg sib dhos thiab tshem tawm cov tub ntxhais.
