Extrusion kub thiab extrusion ceev yog ob qho yooj yim tsis nyob rau hauv extrusion txheej txheem ntawm txhuas profiles. Qhov kub ntawm cov yas deformation cheeb tsam yuav tsum tsim nyog rau qhov kub zoo tshaj plaws rau cov hlau yas.
Qhov loj dua qhov khiav ceev ntawm cov hlau, qhov me me ntawm cov cua sov absorbed los ntawm ib puag ncig nruab nrab, qhov kub thiab txias nyob rau hauv cov yas deformation cheeb tsam, thiab vice versa. Nyob rau hauv ib tug tej yam degree ntawm deformation, los yog xaiv qhov tsim nyog preheating kub, los yog xaiv qhov tsim nyog deformation ceev, qhov kub ntawm lub yas deformation cheeb tsam yuav tsum tau khaws cia nyob rau hauv lub teev ntau yam, thaum lub deformation ceev me me, lub preheating kub yuav tsum tau nce. Thaum lub deformation ceev yog loj, lub preheating kub yuav tsum tau txo, yog li ib tug ntau dua extrusion ceev yuav tau txais los ntawm kev siv txoj kev ntawm "cone" cua sov thiab txias lub pwm;
Nrog rau kev hloov ntawm extrusion tej yam kev mob, lub extrusion kub thiab extrusion ua ceev nyob rau hauv cov txheej txheem extrusion yog tas li hloov.
Thaum extruding aluminium alloy, extrusion kub yog qis ({0}} degree C), qhov ceev extrusion qeeb heev (tsawg dua los yog sib npaug li 25mm / s), thiab thermal conductivity ntawm aluminium alloy siab heev, yog li cov Qhov kub hloov pauv tshwm sim los ntawm cov cua kub ntawm cov hlau extruded thiab cov cua kub sib txawv ntawm cov hlau thiab cov cuab yeej extrusion yuav tsum tau txiav txim siab thaum xam qhov ntsuas kub ntawm cov yas deformation cheeb tsam.
Qhov kub nce hauv cov txheej txheem aluminium extrusion muaj qee yam cuam tshuam rau qhov kub ntawm lub cuab yeej thiab qhov loj ntawm extrusion siab, yog li qhov no yuav tsum tau txiav txim siab tag nrho thaum tsim thiab siv cov extrusion tuag.
