Dab tsi yog cov txiaj ntsig ntawm kev siv aluminium alloys ua cov khoom siv hauv kev lag luam automotive? Qhov zoo ntawm aluminium alloy
Cov ntaub ntawv aluminium alloy tam sim no tau siv dav hauv kev tsim cov khoom siv tsheb, vim cov tsheb tau dhau los ua hnyav dua. Aluminium cov ntaub ntawv yog lub teeb yuag, siab zog, thiab corrosion-resistant, yog li lawv tau siv ntau thiab ntau dua. Hauv qab no, peb yuav luv luv qhia nws cov yam ntxwv ntawm daim ntawv thov.
Cov txiaj ntsig ntawm kev siv aluminium alloys ua cov khoom siv hauv kev lag luam automotive
1. Thaum lub sij hawm extrusion txheej txheem, cov hlau tau ib tug muaj zog thiab ntau yam peb-dimensional compressive kev nyuaj siab lub xeev nyob rau hauv lub extrusion deformation cheeb tsam tshaj nyob rau hauv dov thiab forging. Yog li ntawd, extrusion tuaj yeem siv tag nrho cov plasticity ntawm cov txheej txheem hlau, thiab tuaj yeem siv rau kev ua haujlwm nyuaj rau deform hlau tom qab dov thiab forging, nrog rau kev tsim ntau hom hollow lossis cov khoom sib dhos ua ke.
2. Vim muaj qhov sib txawv geometric cross-section ntawm aluminium alloy profiles, qhov nruj ntawm lawv cov khoom yog qhov siab, uas tuaj yeem ua rau kom nruj ntawm lub tsheb lub cev thiab txhim kho cov yam ntxwv ntawm lub tsheb.
3. Vim muaj peev xwm tswj tau qhov cross-section ntawm aluminium alloy profiles, txhim kho kev ua haujlwm ntawm cov khoom sib xyaw ua ke, txo tus naj npawb ntawm cov khoom, thiab ua tiav vuam qhov chaw los ntawm kev sib txuam ntawm cov ntu ntu.
4. Rau cov khoom lag luam nrog cov txiaj ntsig extrusion, qhov kev ua haujlwm ntev ntev (Rm, Rp0.2) tom qab quenching thiab aging yog ntau dua li cov khoom zoo sib xws ua tiav los ntawm lwm txoj kev.
5. Qhov saum npoo ntawm aluminium extruded khoom muaj xim zoo thiab corrosion kuj, thiab tsis muaj lwm yam kev tiv thaiv corrosion saum npoo yuav tsum tau kho.
6. Extrusion processing muaj siab elasticity, tsis tshua muaj pwm tus nqi, thiab tus nqi qis tsim hloov.
Tsib txoj hauv kev rau kev ua aluminium alloy qhov chaw Ua cov yam ntxwv ntawm aluminium alloy qhov chaw
Aluminium alloy muaj cov yam ntxwv ntawm qhov ntom ntom, siab zog, thiab corrosion kuj. Nws lub teeb yuag thiab lub zog cov yam ntxwv ua rau nws siv dav hauv kev ua thiab kev tsim khoom ntawm ntau qhov chaw. Dab tsi yog tsib txoj hauv kev rau kev ua cov khoom siv aluminium alloy? Tsibtxoj kev rau kev ua aluminium alloy accessories:
1. Stamping ua ntawm aluminium alloy qhov chaw
Stamping yog ib txoj hauv kev tsim thiab ua cov khoom ua haujlwm los ntawm kev siv lub zog sab nraud rau daim hlau, strips, kav, thiab cov ntaub ntawv los ntawm cov xovxwm thiab pwm raws li cov duab thiab qhov loj ntawm cov khoom xav tau, ua rau cov yas deformation lossis sib cais.
2. Mechanical processing ntawm aluminium alloy qhov chaw
Feem ntau yog siv rau hauv cov cuab yeej siv tshuab xws li tsheb, milling, npaj, drilling, thiab sib tsoo rau cov txheej txheem pwm thiab sib sau ua ke rau hauv ntau yam pwm. Kev ua haujlwm ntawm aluminium alloy qhov tseem tuaj yeem hu ua CNC precision machining, tsis siv neeg tshuab dhos machining, CNC tshuab dhos machining, thiab lwm yam.
3. Precision casting ntawm aluminium alloy qhov chaw
Cov khoom tau txais los ntawm txoj kev no feem ntau tsis tas yuav tsum tau siv lub tshuab ntxiv. Precision casting tsim cov duab ntau dua thiab qhov tseeb casting dua li cov txheej txheem machining.
4. hmoov metallurgy ntawm aluminium alloy qhov chaw
Hmoov metallurgy yog cov cuab yeej ntawm kev tsim khoom lossis cov khoom siv hlau hmoov ua raw khoom, los ntawm kev sib tov, sib sau, thiab sintering.
5. Txhaj tshuaj molding ntawm aluminium alloy qhov chaw
Sib tov cov hmoov thiab cov organic sib npaug sib npaug, tom qab granulation, cua sov thiab plasticize nws, txhaj rau hauv pwm kab noj hniav siv lub tshuab txhaj tshuaj molding rau solidification thiab molding. Tshem tawm cov binder los ntawm cov ntawv tsim los siv cov tshuaj los yog thermal decomposition, thiab tau txais cov khoom kawg los ntawm sintering thiab densification.
Peb yam ntxwv ntawm aluminium alloy qhov chaw ua:
Cov txheej txheem aluminium profile muaj peb qhov ua tiav: melting, extrusion, thiab xim (xim xim muaj xws li oxidation, electrophoresis txheej txheem, fluorocarbon spray painting, electrostatic hmoov txau, ntoo grain hloov luam ntawv, thiab lwm yam). Kev ua cov yam ntxwv ntawm aluminium alloy qhov chaw:
1. Tsawg hardness thaum lub sij hawm txhuas alloy ua
Piv rau titanium alloys thiab quenched steel, aluminium alloys muaj qis hardness, thiab ntawm chav kawm, tshav kub kho los yog tuag cam khwb cia txhuas alloys kuj muaj zog dua. Lub HRC hardness ntawm txhuas phaj feem ntau yog qis dua HRC40 degrees. Yog li ntawd, nyob rau hauv cov ntaub ntawv ntawm kev ua aluminium alloy, lub load ntawm lub cuab tam yog me me. Tsis tas li ntawd, aluminium alloy muaj thermal conductivity zoo heev, yog li qhov kub ntawm aluminium alloy milling yog tsawg, uas tuaj yeem txhim kho milling ceev.
2. Tsawg plasticity hauv aluminium alloy ua
Aluminium alloy muaj tsawg plasticity thiab tsawg melting point. Thaum ua cov aluminium alloys, muaj qhov sib sib zog nqus ntug teeb meem, tsis zoo nti tshem tawm kev ua tau zoo, thiab siab roughness. Qhov tseeb, lub ntsiab yog vim li cas rau kev ua aluminium alloy yog tias cov nyhuv ntawm kev txiav thiab roughness tsis zoo. Yog tias ob qhov teeb meem ntawm cov hniav ruaj khov thiab cov tshuab ua kom zoo, qhov teeb meem ntawm aluminium alloy machining tuaj yeem daws tau.
