Dab tsi yog cov khoom siv txhaj tshuaj pwm ua los ntawm?

Cov khoom siv txhaj tshuaj pwm yog tsim los ntawm cov khoom tseem ceeb los xyuas kom meej cov kav ntev, raug thiab zoo ntawm cov khoom kawg.Hauv qab no yog cov ncauj lus kom ntxaws tsom xam ntawm kev txhaj tshuaj molding khoom:

1. Cov khoom tseem ceeb: Hlau

Hlau yog cov khoom siv feem ntau siv hauv kev txhaj tshuaj molding.Nws yog dav siv rau nws cov cuab yeej zoo heev, hnav tsis kam, thermal stability thiab machinability.Muaj ntau ntau hom hlau tuag, feem ntau yog:

(1) Carbon structural steel: xws li S45C, haum rau cov pwm yooj yim lossis cov pwm qis.

(2) Alloy cov cuab yeej hlau: xws li P20, 718, thiab lwm yam, lawv tau txais kev kho cua sov tshwj xeeb thiab kev sib tsoo, nrog lub zog ntau dua thiab hnav tsis kam, haum rau nruab nrab nyuaj thiab tawm los ntawm pwm.

(3) Stainless hlau: xws li S136, nrog zoo heev corrosion kuj, tshwj xeeb tshaj yog haum rau zus tau tej cov tshuaj cov khoom los yog cov zaub mov ntim xav tau siab corrosion kuj pwm.

(4) High-speed steel: siv los tsim pwm qhov chaw uas yuav tsum tau muaj siab hardness thiab hnav tsis kam, xws li txiav npoo.

2, auxiliary khoom: aluminium alloy thiab tooj liab alloy

(1) Aluminium alloy: Txawm hais tias lub zog thiab hnav tsis kam ntawm aluminium alloy tsis zoo li cov hlau, nws lub teeb yuag, zoo thermal conductivity thiab tus nqi qis ua rau nws yog qhov kev xaiv zoo tshaj plaws rau qee qhov qis qis lossis qauv pwm.Aluminium alloy pwm feem ntau yog siv rau kev ua qauv sai lossis cov khoom me me.

(2) Copper alloys: tooj liab alloys, tshwj xeeb tshaj yog beryllium tooj liab, vim nws cov thermal conductivity zoo heev, siab hardness thiab hnav tsis kam, yog siv nyob rau hauv ib co high-precision pwm los tsim inserts los yog txias raws.

3, khoom siv tshwj xeeb

Nrog rau kev nce qib ntawm cov khoom siv science, qee cov ntaub ntawv tshwj xeeb tshiab kuj tau pib siv rau hauv kev txhaj tshuaj pwm, xws li:

(1) Hmoov metallurgy steel: muaj cov qauv microstructure thiab cov khoom siv kho tshuab zoo heev.

(2) Kev ua haujlwm siab ceramics: siv los tsim qee qhov ntawm pwm los txhim kho kev hnav tsis kam thiab thermal stability.

Hauv cov ntsiab lus, cov khoom tsim ntawm kev txhaj tshuaj pwm yog cov hlau, ntxiv los ntawm aluminium alloy thiab tooj liab alloy.Kev xaiv ntawm cov khoom nyob ntawm qhov nyuaj ntawm cov pwm, cov kev xav tau ntau lawm, cov nqi siv nyiaj thiab cov kev xav tau ntawm cov khoom kawg.Kev xaiv cov ntaub ntawv raug tuaj yeem ua kom ntseeg tau tias siv tau ntev thiab ua haujlwm ntawm cov pwm.
