Kev tsim cov kauj ruam ntawm cam khwb cia aluminium cua sov phaj

Cam khwb cia txhuas rhaub yog lub tshuab hluav taws xob uas siv cov tubular hluav taws xob cua sov cov ntsiab lus raws li cov khoom cua sov thiab cov khoom siv aluminium alloy raws li lub plhaub, uas yog tsim los ntawm kev tuag casting. Nws qhov kev ua haujlwm kub yog feem ntau ntawm 150 thiab 450 degrees Celsius, thiab nws tuaj yeem siv dav hauv cov tshuab yas, pwm hau, cable machinery, tshuaj, roj hmab, roj av thiab lwm yam khoom siv.
1. Cov tawv tawv txaus thiab hnav tsis kam: Qhov tawv ntawm cov pwm yas feem ntau yog qis dua 50-60HRC, thiab cov pwm uas tau txais kev kho cua sov yuav tsum muaj qhov hardness txaus los xyuas kom meej tias cov pwm muaj qhov nruj txaus. Vim yog lub siab compressive kev nyuaj siab thiab kev sib txhuam quab yuam uas cov yas ntim thiab ntws hauv pwm thaum lub sijhawm ua haujlwm, nws yuav tsum tau ua kom cov pwm tswj qhov tseeb thiab qhov ruaj khov kom ntseeg tau tias lub neej ua haujlwm txaus. Kev hnav tsis kam ntawm pwm yog nyob ntawm cov tshuaj muaj pes tsawg leeg thiab kev kho cua sov hardness ntawm cov hlau, yog li ua kom lub zog ntawm pwm yog qhov zoo rau kev txhim kho nws cov hnav tsis kam.
2. Muaj peev xwm txiav tau zoo: Feem ntau cov yas tsim pwm yuav tsum tau txiav thiab kho kom haum ntxiv rau EMD ua. Txhawm rau txuas ntxiv lub neej kev pab cuam ntawm cov cuab yeej txiav, txhim kho kev ua haujlwm ntawm kev txiav, thiab txo qhov roughness ntawm cov hlau, cov tawv tawv ntawm cov hlau siv rau cov pwm yas yuav tsum tsim nyog.
3. Kev ua haujlwm zoo polishing: Cov khoom siv yas zoo yuav tsum muaj tus nqi me me rau ntawm qhov chaw ntawm pwm kab noj hniav. Piv txwv li, tus nqi nto roughness ntawm qhov txhaj tshuaj pwm kab noj hniav yuav tsum tsawg tshaj li theem ntawm Ra 0.1-0.25, thaum lub qhov muag qhov muag yuav tsum Ra< 0.01nm, the cavity must be polished to reduce the surface roughness value. The steel selected for this purpose requires minimal impurities, uniform microstructure, no fiber orientation, and no pitting or orange peel like defects during polishing.
4. Zoo thermal stability: Cov duab ntawm cov yas txhaj tshuaj pwm feem ntau nyuaj thiab nyuaj rau tshuab tom qab quenching. Yog li ntawd, nws raug nquahu kom xaiv qhov chaw nrog thermal stability kom ntau li ntau tau. Thaum cov pwm tsim thiab ua tiav los ntawm kev kho cua sov, vim tsis tshua muaj kev nthuav dav coefficient, kev kho cua sov me me deformation, thiab qhov hloov pauv me me los ntawm qhov sib txawv ntawm qhov kub thiab txias, cov qauv metallographic thiab pwm loj yog ruaj khov thiab tuaj yeem txo lossis tsis ua tiav, Qhov no ua kom qhov tseeb qhov tseeb thiab qhov chaw roughness ntawm cov pwm.
5. Cov pa roj carbon steel ntawm qib 50 muaj qee qhov muaj zog thiab hnav tsis kam, thiab feem ntau yog siv los ua cov khoom pwm tom qab quenching thiab tempering kho. Cov cuab yeej carbon siab thiab cov cuab yeej tsis tshua muaj hlau muaj lub zog siab thiab hnav tsis kam tom qab kev kho cua sov, thiab feem ntau yog siv los ua qhov chaw. Txawm li cas los xij, cov cuab yeej carbon siab tsuas yog tsim nyog rau kev tsim cov khoom me me thiab yooj yim zoo li cov khoom vim nws qhov kev kho cua sov loj deformation.
