LPG Lub tog raj kheej Hlau Stamping Tuag, Ib -daim Stamping Moulding

I. Hom Pwm Tsis Ua Haujlwm

(I) Hnav Tsis Tau

1. Kev tshwm sim: Thaum lub sijhawm ua haujlwm, cov pwm maj mam hnav vim kev txav ntawm cov txheeb ze nrog cov khoob, cov khoom ua haujlwm, lossis lwm yam khoom. Qhov hnav no tuaj yeem tshwm sim raws li khawb, abrasions, lossis hnav hnav. Piv txwv li, nyob rau hauv stamping tuag, tsis tu ncua kev sib txhuam ntawm cov xuas nrig ntaus thiab tuag ua rau ntug hnav, cuam tshuam rau qhov tseeb qhov tseeb thiab qhov zoo ntawm qhov chaw stamped.

2. Muaj feem cuam tshuam

Material Hardness: Lub hardness ntawm cov khoom pwm ncaj qha cuam tshuam rau nws hnav tsis kam. Cov ntaub ntawv nrog qis hardness yog yooj yim dua hnav thaum sib txhuam.

Deg Roughness: Qhov ntau dua qhov roughness ntawm qhov chaw, qhov coefficient ntawm kev sib txhuam ntau dua, thiab qhov hnav hnyav dua.

Lubrication Conditions: Lub lubrication zoo tuaj yeem txo kev sib txhuam thiab txo qhov hnav. Tsis muaj lubrication lossis xaiv tsis raug ntawm cov roj nplua nyeem yuav ua rau pwm pwm.

(II) Deformation Failure

1. Kev tshwm sim: Thaum lub sij hawm siv, pwm tau raug kub siab, siab siab, thiab cov khoom siv thauj khoom, ua rau muaj kev hloov pauv ntawm cov duab thiab qhov loj, ua rau muaj kev ua haujlwm tsis zoo. Feem ntau deformation hom muaj xws li khoov, twisting, thiab warping. Piv txwv li, nyob rau hauv kev txhaj tshuaj pwm, thaum molten yas yog txhaj rau hauv kab noj hniav, lub siab tseem ceeb yog generated. Yog hais tias pwm lub zog thiab rigidity tsis txaus, deformation yuav tshwm sim, ua rau muaj teeb meem xws li flash thiab dimensional deviations nyob rau hauv cov khoom yas.

(II) Deformation Failure

1. Kev tshwm sim: Thaum lub sij hawm siv, pwm tau raug kub siab, siab siab, thiab cov khoom siv thauj khoom, ua rau muaj kev hloov pauv ntawm cov duab thiab qhov loj, ua rau muaj kev ua haujlwm tsis zoo. Feem ntau deformation hom muaj xws li khoov, twisting, thiab warping. Piv txwv li, nyob rau hauv kev txhaj tshuaj pwm, thaum molten yas yog txhaj rau hauv kab noj hniav, lub siab tseem ceeb yog generated. Yog hais tias pwm lub zog thiab rigidity tsis txaus, deformation yuav tshwm sim, ua rau muaj teeb meem xws li flash thiab dimensional deviations nyob rau hauv cov khoom yas.

2. Muaj feem cuam tshuam
Mould Structure Design: Ib qho kev tsim qauv tsis tsim nyog yuav ua rau muaj kev ntxhov siab ntau hauv zos ntawm pwm, ua rau deformation. Piv txwv li, cov pwm tsis sib xws ntawm phab ntsa tuab thiab qhov chaw tsis raug ntawm kev txhawb nqa cov tav tuaj yeem txo cov pwm qhov rigidity.

Kev kho cua sov txheej txheem: Kev kho cua sov tsis zoo tuaj yeem hloov kho qhov microstructure thiab cov khoom ntawm cov khoom pwm, cuam tshuam rau nws qhov tsis kam rau deformation. Piv txwv li, qhov kub thiab txias ntau dhau los yog qis qis thiab tsis txaus tempering tuaj yeem ua rau pwm deformation thaum siv.

(III) Fatigue Failure

1. Kev tshwm sim
Thaum rov thauj khoom thiab tshem tawm cov txheej txheem, kev ntxhov siab tshwm sim hauv pwm. Nrog rau lub voj voog nce ntxiv, cov kab nrib pleb tuaj yeem pib ntawm cov ntsiab lus kev ntxhov siab thiab maj mam nthuav tawm, thaum kawg ua rau pwm tawg. Kev qaug zog tsis ua haujlwm feem ntau tshwm sim nyob rau hauv qhov chaw raug hloov pauv, xws li qhov chaw ua haujlwm ntawm ncab tuag thiab khoov tuag.

2. Muaj feem cuam tshuam
Material Toughness: Cov khoom toughness yog ib qho tseem ceeb ntawm kev cuam tshuam rau lub neej qaug zog. Cov ntaub ntawv uas tsis zoo toughness yog feem ntau yuav tawg nyob rau hauv cyclic loading.

Qhov zoo ntawm qhov chaw: Qhov chaw tsis zoo (xws li khawb, microcracks, thiab lwm yam) ua rau muaj kev ntxhov siab ntau ntxiv thiab txo qhov qaug zog ntawm pwm.

(IV) Corrosion Failure

1. Kev tshwm sim: Hauv qhov chaw ua haujlwm, cov pwm tuaj yeem raug corroded los ntawm cov tshuaj lom neeg, ua rau xeb thiab xeb, uas ua rau cuam tshuam rau pwm kev ua haujlwm thiab kev ua neej nyob. Corrosion tsis ua hauj lwm mas manifests pitting corrosion, uniform corrosion, thiab kev nyuaj siab corrosion. Piv txwv li, cov pwm saum npoo yog qhov ua rau corrosion nyob rau hauv qhov chaw ntub dej lossis thaum sib cuag nrog cov kua corrosive.

2. Muaj feem cuam tshuam
Environmental Media: Cov chaw ua haujlwm sib txawv muaj cov tshuaj sib txawv, uas muaj qhov sib txawv corrosiveness rau pwm. Piv txwv li, cov pwm tuaj yeem ua rau corrosion nyob rau hauv ib puag ncig uas muaj cov kua qaub, alkalis, thiab ntsev.

Material Corrosion Resistance: Cov tshuaj muaj pes tsawg leeg thiab microstructure ntawm cov khoom pwm txiav txim siab nws cov corrosion kuj. Qee cov khoom siv hlau muaj qhov zoo corrosion kuj, thaum lwm tus yog yooj yim corroded.
