Dab tsi yog qhov cuam tshuam ntawm kev ua tshuab ntawm precision qhia shafts ntawm lawv cov kev ua tau zoo?

Thaum lub sij hawm ntxhib machining txheej txheem ntawm precision qhia shafts, xws li tig cov ntaub ntawv raw rau hauv ib qho kwv yees ncej-zoo li tus qauv, cov qauv yooj yim thiab loj ntau yam ntawm precision qhia ncej yog txiav txim. Thaum lub sij hawm ntxhib machining ntawm precision qhia shafts, residual kev nyuaj siab yuav raug generated nyob rau hauv cov kev taw qhia ncej vim txiav txiav txiav ntawm cov cuab yeej txiav ntawm cov khoom. Yog tias cov kev ntxhov siab no tsis raug tshem tawm hauv lub sijhawm, lawv tuaj yeem ua rau deformation ntawm precision qhia ncej thaum ua thiab siv tom ntej, cuam tshuam rau nws qhov tseeb ntsuas xws li ncaj thiab cylindricity. Cov txheej txheem sib tsoo hauv kev ua tiav ntawm cov lus qhia precision shafts tuaj yeem tswj qhov tseeb qhov tseeb ntawm cov lus qhia ncej mus rau qib micron. High-precision dimensional control enables precision qhia shafts kom raug phim lwm yam. Piv txwv li, nyob rau hauv lub linear module ntawm automation cov cuab yeej, qhov sib txuam ntawm precision qhia shafts thiab sliders tuaj yeem xyuas kom meej qhov chaw ntawm qhov chaw txav, txo cov suab tshem tawm, thiab txhim kho qhov tseeb ntawm cov khoom siv.
Los ntawm kev sib tsoo zoo thiab polishing thiab lwm yam kev ua tiav, qhov roughness ntawm precision qhia shafts yuav raug txo. Qhov saum npoo roughness feem ntau tuaj yeem ncav cuag Ra{{0}}.2 - Ra0.8μm, thiab cov npoo du tuaj yeem txo qhov kev sib txhuam thiab hnav ntawm qhov chaw mating.
quenching tuaj yeem txhim kho qhov saum npoo los yog tag nrho hardness ntawm precision qhia shafts. Piv txwv li, tom qab siv cov txheej txheem quenching tsim nyog, lub hardness ntawm precision qhia ncej tuaj yeem ncav cuag HRC 50 - HRC60. High hardness enables tus ncej ncej kom zoo dua hnav thiab deformation thaum raug kev sib txhuam thiab siab, tshwj xeeb tshaj yog nyob rau hauv high-load ua hauj lwm ib puag ncig, xws li kis tau tus mob ntawm lub tshuab cuab yeej. Lub quenched precision qhia ncej tuaj yeem ua kom nws qhov tseeb thiab ruaj khov.
Thaum lub sij hawm quenching txheej txheem, vim ceev cua kub thiab txias, thermal stress thiab structural stress yuav raug generated nyob rau hauv lub precision qhia ncej. Yog tias cov kev ntxhov siab no tsis raug tswj xyuas kom zoo, cov lus qhia qhov tseeb yuav raug deformed, xws li khoov, twisting, thiab lwm yam, uas yuav cuam tshuam rau nws qhov tseeb. Yog li ntawd, quenched qhia ncej feem ntau yuav tsum tau tempered kom tshem tawm kev ntxhov siab.
Tempering tuaj yeem tshem tawm cov kev ntxhov siab sab hauv tsim thaum lub sijhawm quenching txheej txheem thiab kho qhov sib npaug ntawm qhov hardness thiab toughness ntawm precision qhia ncej. Los ntawm tempering, lub toughness ntawm precision qhia ncej yog txhim kho, ua rau nws tsis tshua muaj nkig tawg thaum raug cuam tshuam thiab alternating loads. Nyob rau tib lub sijhawm, kev tshem tawm ntawm kev ntxhov siab yuav pab kom rov qab tau qhov tseeb ntawm cov lus qhia precision ncej thiab xyuas kom meej tias nws tuav cov duab zoo thiab qhov tseeb ntawm qhov raug thaum ua tiav thiab siv.
Txhim kho hnav tsis kam: Chrome plating tuaj yeem tsim ib txheej ntawm chromium nrog hardness siab dua rau ntawm qhov chaw ntawm qhov tseeb qhia ncej. Lub hardness ntawm chromium txheej feem ntau tuaj yeem ncav cuag HV800 - HV1200. Cov txheej chromium nyuaj no tuaj yeem txhim kho qhov hnav tsis kam ntawm cov lus qhia precision ncej. Nyob rau hauv cov txheej txheem ntawm kev txheeb ze nrog rau lwm qhov chaw, xws li piston pas nrig daim ntawv thov ntawm cov khoom siv hydraulic, chrome plating txheej tuaj yeem tiv thaiv qhov hnav ntawm qhov taw qhia ncej thiab txuas nws lub neej kev pab cuam.
chrome plating txheej kuj tuaj yeem txhim kho qhov kev tiv thaiv corrosion ntawm daim ntawv qhia ncej, kom nws tuaj yeem ua haujlwm ib txwm nyob hauv qhov chaw ntub lossis me ntsis corrosive. Cov txheej txheem chrome plating tuaj yeem tswj tau qhov tuab ntawm chrome plating txheej, yog li txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhav) chrome plating nws tuaj yeem tswj hwm qhov tuab ntawm chrome plating.
Txoj kev kho nitriding tuaj yeem tsim cov txheej nitride rau ntawm qhov chaw ntawm cov ntawv qhia ncej, uas muaj cov hardness siab, hnav tsis kam thiab tiv thaiv qaug dab peg. Txawm li cas los xij, yog tias cov txheej txheem nitriding tsis raug tswj kom zoo, qhov kev loj hlob ntawm cov txheej txheem nitride tsis sib npaug, uas yuav ua rau muaj kev hloov pauv tsis sib xws ntawm cov tawv tawv thiab qhov loj ntawm cov ncej, yog li cuam tshuam rau nws qhov tseeb. Yog li ntawd, tsis muaj xws li kub, lub sij hawm, thiab roj txaus tus nqi thaum lub sij hawm tus txheej txheem nitriding yuav tsum tau nruj me ntsis tswj kom lub zoo ntawm nitride txheej thiab qhov tseeb ntawm precision qhia ncej ncej.
Yog tias koj xav nkag siab txog qhov cuam tshuam ntawm kev ua cov thev naus laus zis ntawm cov lus qhia precision ntawm nws qhov kev ua tau zoo, koj tuaj yeem sab laj nrog peb cov kws tshaj lij, thiab peb yuav ua haujlwm rau koj tag nrho 24 teev hauv ib hnub!
