Taw Qhia Rau Cov Txheej Txheem Rolling Ntawm Precision Piston Rods

Precision piston pas nrig yog tsuas yog siv rau piston pas nrig hauv hydraulic pneumatics, engineering machinery, thiab tsheb tsim. Nws yog ua tiav los ntawm dov, vim tias cov txheej txheej saum npoo muaj qhov seem compressive kev ntxhov siab ntawm qhov chaw, uas yog qhov tsim nyog rau kev tsim cov kab nrib pleb me me ntawm qhov chaw.

kaw, cuam tshuam qhov nthuav dav ntawm kev ua haujlwm erosive. Yog li ntawd, qhov kev tiv thaiv corrosion ntawm qhov chaw tuaj yeem txhim kho, thiab kev tsim los yog nthuav tawm ntawm kev qaug zog tawg tuaj yeem ncua, yog li txhim kho lub zog qaug zog ntawm lub tog raj kheej pas nrig. Los ntawm yob txoj kev, txheej txheej ua haujlwm txias yog tsim rau ntawm qhov chaw dov, uas txo cov elastic thiab yas deformation ntawm kev sib cuag ntawm cov sib tsoo khub, yog li txhim kho qhov hnav tsis kam ntawm lub tog raj kheej pas nrig thiab tsis txhob hlawv los ntawm kev sib tsoo. . Tom qab dov, qhov txo qis ntawm qhov roughness tus nqi tuaj yeem txhim kho cov khoom haum. Nyob rau tib lub sijhawm, kev sib txhuam kev puas tsuaj rau lub nplhaib foob los yog lub foob thaum lub piston pas nrig txav tau raug txo, thiab tag nrho cov kev pabcuam lub neej ntawm cov khoom raug txhim kho.

Cov txheej txheem dov yog cov txheej txheem zoo ntsuas. Tom qab dov, qhov roughness ntawm qhov precision piston pas nrig yog txo los ntawm Ra3.2 ~ 6.3μm ua ntej dov mus rau Ra0.4 ~ 0.8μm, thiab lub hardness saum npoo yog nce li ntawm 30 feem pua. .

Ntog qaug zog lub zog nce 25 feem pua. Kev pabcuam lub neej ntawm cov khoom yog nce los ntawm 2 mus rau 3 zaug, thiab cov txheej txheem dov yog li 15 npaug ntau dua li cov txheej txheem sib tsoo. Cov ntaub ntawv saum toj no qhia tau hais tias cov txheej txheem dov tuaj yeem txhim kho qhov zoo ntawm cov khoom.
