Ndondomeko ya Aluminium extrusion:
Extrusion yeniyeni idayamba ndi extrusion cast mu aluminiyamu ndodo, aluminiyumu yoponyera ndodo iyenera kutenthedwa isanafike extrusion kuti ichepetse, zotenthetsera zabwino zotayidwa zoponyera ndodo sheng ingot zimayikidwa mu mbiya ya extruder mkati, kenako ndikuyendetsedwa ndi mphamvu yamagetsi yamagetsi yayikulu, ndodo Kutsogolo kwa ndodo ya extrusion kumakhala ndi pini yamagetsi, yotenthetsera zotsekemera zotsekemera zotsekemera mu dummy block atapanikizika kwambiri kuchokera ku nkhungu mwatsatanetsatane akamaumba extrusion, pezani chomaliza.
The zotayidwa bala ndi akusowekapo za ndondomeko extrusion. Bokosi la aluminiyamu la extrusion limatha kukhala lolimba kapena lopanda pake, nthawi zambiri limakhala laling'ono, ndipo kutalika kwake kumatsimikizika ndi zotumphukira za extrusion.Aluminiyamu mipiringidzo nthawi zambiri imaponyedwa, ina imakopeka kapena kukanikizidwa.Nthawi zambiri imapangidwa ndikucheka ma aloyi a aluminiyamu okhala ndi aloyi wabwino.Zokondazo nthawi zambiri zimatenthedwa mpaka madigiri a 450 mu ng'anjo yotentha isanatumizidwe, ndipo pafupifupi 10% imatsalira mu ingots.
Gulu la njira za extrusion:
1. Malinga ndi malangizo a extrusion: patsogolo extrusion, reverse extrusion, lateral extrusion
2. Malinga ndi mawonekedwe a mapindikidwe: ndege mapindikidwe extrusion ofananira symmetry mapindikidwe extrusion ambiri azithunzi omwe tikunena
3. Malinga ndi kondomu momwemo: palibe kondomu yoperekera mafuta oyenera kutsata
Ubwino wa kukonza kwa extrusion:
1. Kuchepetsa luso mapindikidwe zitsulo
The extrusion chiŵerengero cha zotayidwa koyera angafikire 500, ndi extrusion chiŵerengero cha mkuwa wangwiro angafikire 400, ndi extrusion chiŵerengero cha chitsulo angafikire 40-50.
2. Zogulitsa zakutali ndizabwino kwambiri
Kusintha kwa extrusion kumatha kukonza ma microstructure komanso makina azitsulo, makamaka pazitsulo zina zotayidwa ndi extrusion athari, kotenga nthawi (extrusion malangizo) makina azinthu zopangidwako atatha kuzimitsa ndi ukalamba ndizokwera kwambiri kuposa zinthu zofananira zopangidwa ndi njira zina zakukonzera .
3. Zogulitsa zotulutsira zili ndimitundu yambiri
Kukonzekera kwa extrusion sikungangopanga chitoliro, ndodo ndi waya wokhala ndi mawonekedwe osavuta, komanso kumatha kupanga magawo olimba komanso osalongosoka okhala ndi mawonekedwe ovuta kwambiri, ndi magawo amitundu yosintha mosintha pang'onopang'ono komanso kusintha pang'ono pang'ono mbali yayitali ya gawo lazogulitsa.
Kukula kwake kulinso kotambalala kwambiri, kuyambira machubu akulu kwambiri ndi mbiri zomwe zili ndi magawo okhala ndi bwalo lakunja la 500-1000mm mpaka laling'ono kwambiri kutulutsa mwatsatanetsatane ndi zigawo kukula kwa timitengo ta machesi.
