Kev tsim cov txheej txheem ntawm aluminium bronze bearings

1. Kev tswj kev sib xyaw: Kev ua haujlwm ntawm aluminium bronze yog ze ze rau nws cov tshuaj muaj pes tsawg leeg. Nws yog ib qho tsim nyog los tswj cov ntsiab lus thiab kev faib ua feem ntawm cov ntsiab lus xws li tooj liab thiab txhuas kom ntseeg tau tias cov alloy muaj qhov xav tau siab zog, hnav tsis kam, corrosion kuj thiab lwm yam khoom.

2. Cov txheej txheem melting:

Oxidation thiab gas absorption: Thaum lub sij hawm smelting txheej txheem, cov khoom xws li txhuas yog yooj yim oxidized los ua high-melting-point oxide inclusions, uas txo cov kev ua tau zoo thiab zoo ntawm cov hlau. Nyob rau tib lub sijhawm, nws kuj tseem tuaj yeem nqus cov pa roj (xws li hydrogen), uas ua rau muaj qhov tsis xws luag xws li pores hauv cov castings. Yuav kom daws tau qhov teeb meem no, nws yog ib qho tsim nyog yuav tau txais ib txoj kev smelting uas tsim nyog (xws li qhov nruab nrab zaus los yog kev lag luam zaus coreless induction rauv smelting), ntxiv cov tshuaj npog thiab cov tshuaj ua kom zoo (xws li cryolite), thiab sim kom tsis txhob overheating ntawm cov yaj mus. txo oxidation thiab gas absorption.

Kev tswj qhov kub thiab txias: Lub melting kub yuav tsum tau tswj kom meej. Qhov kub thiab txias heev yuav ua rau cov hlawv thiab oxidation ntawm cov ntsiab lus, thaum qhov kub thiab txias yuav ua rau cov hlau tsis sib xws thiab cov dej tsis zoo, cuam tshuam rau qhov zoo ntawm casting.

3. Casting txheej txheem:

Solidification shrinkage: Aluminium bronze yuav shrink zoo heev thaum lub sij hawm solidification txheej txheem. Yog tias cov txheej txheem casting tsis tsim nyog, nws yog ib qho yooj yim los tsim qhov tsis xws luag xws li shrinkage kab noj hniav thiab shrinkage, uas yuav cuam tshuam rau qhov ceev thiab mechanical zog ntawm cov kabmob. Yuav kom daws tau qhov teeb meem no, nws yuav tsum tau txais yuav ib tug tsim nyog casting txoj kev (xws li semi-nruam casting), optimize pwm tsim, teem tsim nyog risers thiab chills, thiab lwm yam kom them rau lub solidification shrinkage.

.Segregation teeb meem: Alloy cov ntsiab lus yuav cais thaum lub sij hawm solidification txheej txheem, ua rau lub zos tsis sib xws thiab cuam tshuam rau cov uniformity ntawm bearing kev ua tau zoo. Kev sib cais tuaj yeem raug txo los ntawm kev ua kom zoo dua melting thiab casting txheej txheem tsis, siv tsim nyog stirring los yog vibration txoj kev, thiab lwm yam.

4. Cov txheej txheem kev kho cua sov: kev kho cua sov yog ib qho tseem ceeb hauv kev txhim kho kev ua haujlwm ntawm txhuas bronze bearings, tab sis cov txheej txheem tswj tsis yooj yim. Piv txwv li, qhov kub thiab txias, lub sij hawm thiab txias npaum li cas ntawm cov tshuaj kho, qhov kub thiab txias thiab lub sij hawm ntawm kev laus kev kho mob, thiab lwm yam., txhua yam yuav tsum tau precisely kho raws li ib tug tshwj xeeb alloy muaj pes tsawg leeg thiab kev ua tau zoo. Yog tias qhov ntsuas tsis tsim nyog, qhov kev xav tau ntawm kev txhim kho kev ua haujlwm yuav tsis ua tiav, thiab nws tuaj yeem ua rau kev ua haujlwm tsis zoo lossis qhov tsis zoo tshiab.

5. Machining: Aluminium bronze muaj siab zog thiab hardness, uas coj tej yam nyuaj rau machining, xws li loj txiav quab yuam, ceev cov cuab yeej hnav, thiab tsis yooj yim los xyuas kom meej qhov zoo ntawm machined nto. Nws yog ib qho tsim nyog los xaiv cov txheej txheem machining tsim nyog, cov khoom siv thiab cov duab geometric, thiab siv cov kev ntsuas cua txias thiab lubrication kom tsim nyog los txhim kho kev ua haujlwm zoo thiab zoo.

6. Kev kho deg: txhawm rau txhim kho corrosion kuj, hnav tsis kam lossis lwm yam khoom ntawm txhuas bronze bearings, feem ntau yuav tsum tau kho deg, xws li chrome plating, zinc plating, phosphating, thiab lwm yam. Txawm li cas los xij, cov teeb meem kuj tseem tshwm sim thaum lub sij hawm nto. txheej txheem kev kho mob, xws li tsis zoo txheej adhesion, tsis sib xws thickness, nto roughness uas tsis tau raws li qhov yuav tsum tau, thiab lwm yam, thiab cov txheej txheem kho deg thiab zoo yuav tsum tau nruj me ntsis tswj.

7. Kev soj ntsuam zoo thiab kev tswj hwm: Vim tias qhov kev ua tau zoo ntawm cov txhuas bronze bearings, kev soj ntsuam zoo thiab nruj yuav tsum tau ua rau cov khoom siv raw, cov khoom nruab nrab (xws li cov khoom siv, cov ntawv sau) thiab cov khoom tiav, suav nrog tshuaj lom neeg kev tshuaj ntsuam xyuas, kev ntsuas cov khoom siv tshuab. , metallographic qauv kev soj ntsuam, kev soj ntsuam tsis muaj kev puas tsuaj, thiab lwm yam los xyuas kom meej tias cov khoom ua tau raws li cov qauv tsim thiab cov qauv tsim, uas tseem yuav ua rau kom qhov nyuaj thiab nyuaj ntawm cov txheej txheem tsim khoom.

Kev tsim cov txheej txheem nyuaj ntawm txhuas bronze bearings feem ntau suav nrog cov khoom saum toj no. Yog tias koj xav paub ntau ntxiv txog kev tsim cov txheej txheem ntawm txhuas bronze bearings, thov xyuam xim rau www.cn-czpufa.com
