Yuav ua li cas ntawm extrusion, ib daim ntawv tso rau hauv lub chamber? Nqe lus piav qhia: In forward extrusion, ib daim ntawv tso rau hauv lub chamber thiab yuam los ntawm qhov qhib tuag los ntawm hydraulically tsav ram. Qhov qhib tuag yuav yog puag ncig, lossis nws yuav muaj ntau yam duab, nyob ntawm qhov xav tau profile.
Yuav ua li cas ntawm cov txheej txheem forging hlau yog khaws cia nyob rau hauv nruab nrab ntawm ib tug khub ntawm tuag thiab ib tug gutter yog muab nyob rau hauv qis tuag?
Kev piav qhia: hauv kaw tuag forging txheej txheem hlau yog khaws cia nyob rau hauv nruab nrab ntawm ib khub ntawm cov tuag thiab ib lub qhov dej yog muab rau hauv qis tuag. nyob rau hauv kev xav tuag forging txheej txheem hlau yog khaws cia nyob rau hauv nruab nrab ntawm ib tug khub ntawm tuag thiab tsis muaj gutter yog muab nyob rau hauv qis tuag.
Nyob rau hauv qhov twg ntawm cov txheej txheem forging hauv qab no yog tsim?
Closed tuag forging nrog flash muaj kev kub ntxhov ntawm ib daim duab hluav taws xob nruab nrab ntawm ob feem ntawm qhov tuag, feem ntau yog txuam nrog poj niam impressions. Cov hlau ntau dhau yog nyem tawm ntawm cov kab tuag thiab hu ua "flash" (cov tuag yog tsim nrog lub teeb av thiab gutter).
Dab tsi yog cov duab ntawm cov pob zeb siv hauv txheej txheem extrusion?
3. Dab tsi yog cov duab ntawm lub billet siv hauv txheej txheem extrusion? Kev piav qhia: Cov duab ntawm cov pob zeb hauv cov txheej txheem extrusion yog tsim los ua cylindrical nkaus xwb. Lub cubical lossis spherical lossis pyramidal billet tsis tuaj yeem tsim kom muaj txiaj ntsig zoo.
Thaum kub npaum li casforging yog nqa tawm?
Kub forging ntawm hlau: Lub forging kub yog siab tshaj qhov kub ntawm recrystallization, thiab feem ntau yog nruab nrab ntawm 950 ° C ~ 1250 ° C. Feem ntau, ib qho kev paub zoo (piv txwv li, filling ntawm tuag-kab noj hniav nyob rau hauv cov ntsiab lus ntawm forging), tsawg tsim rog, thiab ib tug yuav luag uniform tensile zog ntawm lub workpiece.
