Qhov txawv ntawm casting thiab forging yog dab tsi?

Muaj ntau cov txheej txheem nrog cov npe zoo sib xws hauv kev lag luam, tab sis muaj qhov sib txawv ntawm lawv, xws li casting thiab forging.

Taw qhia rau casting thiab forging

Casting: molten kua hlau nyob rau hauv pwm kab noj hniav kom txias, thiab cua qhov yooj yim tshwm sim nyob rau hauv nruab nrab ntawm qhov chaw;Tshav kub thiab yaj cov hlau thiab hliv rau hauv cov xuab zeb pwm lossis pwm.Tom qab txias, nws yuav solidify rau hauv ib lub tais.
Forging: Nws yog tsim los ntawm extrusion ntawm qhov kub thiab txias, uas tuaj yeem kho cov nplej hauv qhov chaw.Cov khoom siv hlau hauv lub xeev yas tuaj yeem hloov mus rau hauv ib qho chaw ua haujlwm nrog qee yam duab thiab qhov loj me los ntawm kev sib tsoo thiab lwm txoj hauv kev, thiab nws lub cev muaj zog tuaj yeem hloov pauv.

Qhov txawv ntawm casting thiab forging

1. Cov txheej txheem tsim khoom sib txawv

Casting yog tsim ib zaug.Tom qab cov hlau yog melted rau hauv cov kua, nws yog poured rau hauv lub casting kab noj hniav sib haum mus rau cov duab ntawm ib feem, thiab ces nws yog txias, solidified thiab ntxuav, thiaj li yuav tau txais cov txheej txheem ntawm cov khoom los yog burrs.Qhov tshwj xeeb casting tshwj xeeb tsom rau cov txheej txheem hlau melting thiab cov txheej txheem tswj hauv cov txheej txheem casting.
Forging yog qeeb txoj kev.Lub tshuab forging yog siv los ua kom lub zog ntawm cov hlau seem, nyem, rauj thiab lwm txoj hauv kev los ua cov khoom siv hlau hauv lub xeev yas los ua cov txheej txheem ua haujlwm nrog qee cov duab thiab qhov loj ntawm workpiece.Forging yog ib tug yas tsim nyob rau hauv cov khoom ntawm lub xeev, uas yuav muab faib ua kub ua thiab txias ua, xws li extrusion drawing, pier roughening, xuas nrig ntaus, thiab lwm yam

2. Kev siv sib txawv

Forging feem ntau yog siv rau kev ua ntawm forgings nrog tej yam zoo li thiab loj.Casting yog ib qho kev lag luam zoo rau kev tsim qhov tsis xws luag, thiab feem ntau yog siv rau qhov chaw nrog cov duab nyuaj.

3. Qhov zoo sib txawv

Forging zoo:

Forging tuaj yeem tshem tawm qhov tsis xws luag xws li-cam khwb cia porosity tsim nyob rau hauv cov txheej txheem smelting ntawm hlau, optimize microstructure.Nyob rau tib lub sij hawm, vim hais tias tag nrho cov hlau ntws kab yog khaws cia, txhua yam khoom ntawm forgings feem ntau zoo dua li cov castings ntawm tib cov khoom.Rau cov khoom tseem ceeb uas muaj kev thauj khoom siab thiab kev ua haujlwm hnyav hauv cov tshuab ua haujlwm, forgings feem ntau yog siv tshwj tsis yog rau daim hlau, profiles lossis weldments nrog cov duab yooj yim uas tuaj yeem dov.
Casting qhov zoo:

1. Nws tuaj yeem tsim cov khoom nrog cov duab sib txawv, tshwj xeeb tshaj yog cov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.

2. dav adaptability.Cov ntaub ntawv hlau feem ntau siv hauv kev lag luam tuaj yeem raug cam khwb cia, los ntawm ob peb grams mus rau pua pua tons.

3. Ntau qhov chaw ntawm cov khoom siv raw thiab tus nqi qis, xws li cov khoom seem, cov khoom seem, chips, thiab lwm yam.

4. Cov duab thiab qhov loj ntawm cov casting yog ze heev rau cov khoom, uas txo cov nqi txiav thiab belongs rau kev ua tsis tiav.

5. Nws yog dav siv.40% ~ 70% ntawm cov tshuab ua liaj ua teb thiab 70% ~ 80% ntawm cov cuab yeej siv tshuab yog castings.

4. Qhov tsis zoo yog qhov sib txawv

Forging defect: Nyob rau hauv forging ntau lawm, nws yog ib qho yooj yim ua rau raug mob
Casting defects:

1. Cov khoom siv tshuab tsis zoo rau forgings, xws li cov qauv ntxhib thiab ntau yam tsis xws luag.

2. Nyob rau hauv cov xuab zeb casting, ib thooj, me me batch ntau lawm thiab siab siv zog ntawm cov neeg ua haujlwm.

3. Qhov zoo ntawm casting tsis ruaj khov, muaj ntau cov txheej txheem, qhov cuam tshuam cuam tshuam yog qhov nyuaj, thiab ntau yam tsis xws luag yog yooj yim tshwm sim.
