Yuav Ua Li Cas Txheej Txheem CK 45 Hlau Precision Chromed Piston Qws
Sep 06, 2023
(1) Thaum CK 45 Steel Precision Chromed Piston Qws yog siv ib txwm, lub piston pas nrig yog raug rau alternating loads thiab saum npoo yog reciprocated los ntawm kev sib txhuam, yog li ntawd tus pas nrig piston yuav tsum yog ob qho tib si nyuaj thiab hnav-resistant.
(2) 38CrMoALA cov khoom siv, thiab ib feem ntawm nws tau quenched thiab tempered thiab nto nitriding kho. Lub hardness tseem ceeb yog 28-32HRC, thiab lub hardness saum npoo yog 62-65HRC.
(3) Thaum ua cov piston pas nrig, ntxhib tig thiab ua tiav tiav yuav tsum tau ua tiav cais kom tsis txhob deformation ntawm lub workpiece thaum ua. Thiab siv tus ncej nruab nrab thaum ua cov xov ntawm ob qho kawg.
(4) Thaum xaiv qhov positioning datum, tag nrho cov txheej txheem ua yuav tsum tau txais ob lub qhov chaw qhov chaw txoj kev, thiab standardization yog unified. Qhov no yog ua los xyuas kom meej lub coaxiality kam rau ua ntawm qhov chaw thiab qhov tseeb ntawm kev sib nrig sib txoj hauj lwm ntawm txhua qhov chaw.
(5) Thaum sib tsoo lub voj voog sab nrauv, lub qhov nruab nrab yuav tsum tau kho. Thiab qhov dav ntawm lub log sib tsoo yuav tsum nqaim kom txo tau lub zog sib tsoo radial.
(6) Thaum sib tsoo lub taper, daim ntawv xeem yuav tsum yog hauv av ua ntej, thiab lub taper tsuas tuaj yeem ua hauv av tom qab daim ntawv xeem tau dhau qhov kev tshuaj xyuas kev sib tsoo.
(7) Kev tuav ncaj nraim tsis pub nyob rau hauv tag nrho cov txheej txheem ntawm kev ua; Thaum lub sijhawm ua haujlwm nitriding, cov xov ib feem ntawm lub piston pas nrig yuav tsum muaj cov cuab yeej tiv thaiv los ua lub luag haujlwm tiv thaiv.
