Yuav ua li cas ua extrusion tshuab pwm?
Machining thiab casting yog ob txoj kev los tsim cov pwm kab noj hniav.Qhov yog siv nyob ntawm ntau yam, xws li cov khoom pwm, cov kabmob pwm, qhov tsis muaj kab noj hniav thiab qhov yuav tsum ua kom kab noj hniav.
Pwm cov khoom yog qhov tseem ceeb tshaj plaws hauv kev txiav txim siab txoj kev tsim tawm.Txhua yam yog nyuab dua povtseg, tsuas yog qee yam xwb
Aluminium alloys yog nrum.Generally hais lus, aluminium alloy nrog siab silicon cov ntsiab lus yog feem ntau haum rau casting, thaum txhuas alloy nrog siab zog tsis tau cam khwb cia thiab yuav tsum tau machined.Copper beryllium alloy mould muaj kev kawm zoo.Feem ntau cov pwm molds machined thiab manufactured, thaum cov zinc alloys yog yooj yim nrum.
Yog hais tias tus kab npoo loj loj, kab noj hniav los sis tsis sib haum, kab noj hniav loj me me yuav tsum tsis tshua muaj, kab noj hniav yog loj los yog ntau lawm ntim tsawg dua, casting txoj kev yuav siv los tsim cov pwm.Tus nqi ntawm casting tuag tsawg, tab sis nws cov thiab thermal conductivity muaj tsawg tshaj li cov neeg ua haujlwm tuag.Txhua yam tshwj xeeb casting kev siv tau los tsim cov kev ua haujlwm siab tuaj pwm. Piv txwv li, cov yeeb yaj kiab siab tuaj yeem txo qhov porosity ntawm aluminium thiab copper beryllium alloy thiab lav lub siab precision ntawm cov pwm kab noj hniav.Qhov kev ua haujlwm ntawm lub tshuab pwm kab noj hniav yog tsuas yog milling, sib tsoo, thiab lwm yam.
Kuj muaj extrusion txias, kub extrusion, edm thiab welding txujci.Tus txias extrusion txujci no haum rau cov pwm me me, tshwj xeeb tshaj yog rau cov kab noj hniav ntau pwm, los xyuas kom meej cov taub hau ntawm txhua kab noj.Kev loj ntim (xws li 3m3) thiab kev siv welding yuav siv tau los tsim lawv.Thaum siab yog qhov yuav tsum tau, cov pwm kab noj hniav yuav tsum raug tsim los ntawm kev luam milling.Qhov yuav tsum tau muab rau hauv tus account thaum tsim cov kab noj hniav loj.Rau cov kab noj hniav, shrinkage suav shrinkage ntawm tshuab molding khoom thiab shrinkage tom qab cov pwm ua.Rau cov kab noj hniav, qhov ntsws cov nqi hauv txoj kev ua tus casting kuj yuav tsum raug xam tias.
Qhov kawg theem ntawm kev tsim kab noj hniav yog polishing, sandblasting los yog etching.Ua ntej kev cuam tshuam, tshwj xeeb tshaj yog thaum tsim nyog rau etch zoo qauv, nplai thiab cov qhab nia tsim los ntawm txiav, edm, sib tsoo los yog extrusion yuav tsum tau muab tshem tawm kom paub meej txog ib theem ntawm kev tiav. Cov kab noj hniav no feem ntau tsis sib zog thiab tsis tshua muaj plated nrog hlau (xws li, chromium) tshwj tsis yog tias lawv tau ua rau cov pob loj loj.Yog hais tias qhov kab noj yuav tawv los yog chrome plated, nws yuav tsum tau ua tiav tom qab roj hmab.
Clamping billet inlay, rub pas nrig, qhia ntawv thiab qhia lub tes tsho, thiab lwm yam. Feem ntau ntawm cov hlau los yog tooj hlau beryllium alloy los ntawm kev ua vaj tse ua, tab sis kuj los ntawm hardening.
