Casting pwm txhais tau hais tias txhawm rau kom tau txais cov qauv zoo ntawm ib feem, lwm yam khoom siv tau yooj yim moldable yog siv los ua cov qauv ntawm cov khoom ua ntej, thiab tom qab ntawd cov pwm tau muab tso rau hauv cov xuab zeb pwm, yog li cov kab noj hniav nrog tib yam qauv. loj raws li ib feem yog tsim nyob rau hauv cov xuab zeb pwm. Tom qab ntawd ncuav ib cov kua dej rau hauv cov kab noj hniav. Tom qab cov kua txias thiab solidifies, ib feem nrog raws nraim tib yam zoo thiab cov qauv raws li cov pwm tuaj yeem tsim.
duab
Muaj ntau cov txheej txheem rau molding, uas feem ntau muab faib ua pawg hauv qab no raws li kev ua haujlwm sib txawv:
1. Ordinary tuag forging:
Ordinary tuag forging tso ib lub rhuab los yog unheated hlau dawb paug nyob rau hauv lub pwm kab noj hniav. Nyob rau hauv qhov kev txiav txim ntawm kev cuam tshuam los yog siab. Cov duab geometric ntawm cov hlau yog hloov pauv kom tau txais ib qho forging uas zoo ib yam nrog cov kab noj hniav. Common tuag forging muaj xws li kub forging thiab pier forging. Dun forging kuj muab faib ua pier sov, txias pier thiab kub pier;
2. Extrusion:
Extrusion yuav muab cov khoom siv hlau tso rau hauv cov qauv extrusion kab noj hniav. Siv lub zog siab ntawm ib qho kawg. Cov khoom siv casting pwm yog deformed nyob rau hauv peb txoj kev. Tom qab ntawd nws ntws tawm ntawm qhov tuag qhov ntawm ib kawg. Tau txais cov khoom sib txawv. Muab faib raws li qhov txheeb ze txav ntawm cov punch thiab cov khoom. Extrusion tuaj yeem muab faib ua rau pem hauv ntej extrusion, thim rov qab extrusion, compound extrusion, radial extrusion, thiab lwm yam raws li qhov kub thiab txias, nws tuaj yeem muab faib ua kub extrusion, txias extrusion thiab sov extrusion;
3. Kev rub tawm:
Thaum lub sij hawm kos duab, cov khoom yog compressed nyob rau hauv ob txoj kev thiab stretched nyob rau hauv ib qho kev taw qhia. Zoo li tus tuag qhov ntawm lub casting pwm. Tau qhov khoob, profiles thiab qhov chaw ntawm cov duab thiab qhov ntau thiab tsawg. Kev kos duab tuaj yeem muab faib ua extubation, kos duab, thiab lwm yam. Cov khoom tau txais los ntawm kev kos duab muaj qhov ua tau zoo thiab qhov tsis zoo ntawm qhov roughness, thiab feem ntau yog siv los ua cov txheej txheem dov thiab cov kav dej kom zoo dua qub;
4. Stamping:
Stamping siv ib tug tuag deform los yog cais cov ntaub ntawv. Yuav kom tau txais cov txheej txheem ntawm cov khoom. Stamping tuaj yeem tsim cov khoom nrog cov duab nyuaj, qhov zoo ntawm qhov zoo, thiab siab precision. Casting pwm muaj cov khoom lag luam siab thiab cov nqi qis tib lub sijhawm. Stamping tuaj yeem faib ua ob hom: txheej txheem tsim thiab txheej txheem sib cais. Cov txheej txheem sib cais muaj xws li xuas nrig ntaus, blanking, trimming, trimming thiab lwm txoj kev; cov txheej txheem tsim muaj xws li kos duab, khoov, nthuav dav, rummaging, leveling, thiab lwm yam .;
5. Tuag casting:
Tuag casting yog txheej txheem uas cov hlau molten yog txhaj rau hauv qhov tuag-casting qauv kab noj hniav ntawm kev kub ceev nyob rau hauv ib tug tej yam siab thiab solidified nyob rau hauv siab los tsim ib tug casting;
6. Yas molding:
Yas molding yog cov pwm pwm uas pwm cov hmoov los yog cov kua dej yas hauv qab qhov kev txiav txim siab kom tau cov khoom yas ntawm qhov xav tau thiab qhov loj me. Yas molding tuaj yeem muab faib ua extrusion molding, compression molding, txhaj tshuaj molding thiab lwm yam txheej txheem
