Njira yopangira aluminium extrusion imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha kusinthasintha kwake komanso kutsika mtengo. Komabe, chinthu chimodzi chofunikira chomwe sichinganyalanyazidwe munjira imeneyi ndi mlingo wa kulolerana. Kulekerera ndizofunikira kwambiri pozindikira kufunika kwa miyeso yazinthu. Kukwaniritsa kulekerera koyenera ndikofunikira pakuwonetsetsa kuti kupanga kopanda phindu popanda kusokoneza ntchito ndi kukwanira kwa gawolo.

N’chifukwa chiyani kulolera kuli kofunika kwambiri?

Izi ndi zifukwa zazikulu:

* Kukwaniritsa zofunikira zogwirira ntchito

*Kusankha mavalidwe apamwamba ovomerezeka

* Kuthekera kopanga mawonekedwe ofunikira a extrusion, yomwe imakhudzidwa ndi zovuta za mbiriyo komanso ngati ili yotseguka kapena yotsekedwa.

*Kukhazikitsa zofunikira zamaukadaulo atolankhani, monga kuziziritsa, mbali yotuluka ndi kutentha koyambira

Kodi kulolerako kumakhudza chiyani?

Aluminium extrusion amadziwika kwambiri chifukwa cha mphamvu zake komanso kudalirika kwake. Pogwiritsa ntchito kutentha kwa aluminiyamu ndikukankhira kupyolera mu kufa ndi mawonekedwe enieni, mbiri yomwe mukufuna imakwaniritsidwa. Komabe, pali zinthu zambiri zomwe zingakhudze kulolerana kwa ma profaili owonjezera.

1, zigawo za alloy zomwe zimagwiritsidwa ntchito pochita izi: Aloyi iliyonse imafunikira njira inayake yopangira, ndipo njira yoziziritsa imagwira ntchito yofunika kwambiri pakupanga mbiri ndikuzindikira kulolerana. Ma aloyi ena angafunikire kuziziritsa pang'ono, pamene ena amafunika kuziziritsa kwambiri, ngakhale kugwiritsa ntchito madzi m'malo mwa mpweya. Ma alloys ovuta kwambiri amatha kuyika zoletsa ndikupangitsa kuti zikhale zovuta kukwaniritsa kulolerana kolondola.

2, zinthu zamankhwala: zolemera kwambiri zotayira zimakhala ndi zinthu monga manganese, zinki, chitsulo, mkuwa, ndi vanadium. Mwachitsanzo, Vanadium ndiyofunikira kuti ma alloys azitha kuwonongeka pamsika wamagalimoto. Zinthu izi zimatha kukhudza kwambiri kuvala kwa ma dies omwe amagwiritsidwa ntchito mu extrusion, omwe, nawonso, amakhudza kukula kwa mbiri, makamaka kulolerana. Pamene kufa kumakhalabe kugwiritsidwa ntchito kwa nthawi yayitali, pakhoza kukhala kuchulukitsidwa kwa ma profailo.

3, Kutentha kwa Aluminiyamu: Kutentha kwapamwamba kungayambitse kulolerana kwakukulu kwa aluminiyamu extrusion chifukwa cha kukula ndi kufewetsa kwa zinthuzo.

4, Micro-structure: mawonekedwe ang'onoang'ono a aluminiyamu, monga kukula kwa tirigu ndi mawonekedwe ake, amatha kukhudza makina ndi kukhazikika kwa mawonekedwe, kukhudza kulolerana kwa zinthu za aluminiyamu zowonjezera.

5, Die design: Die design imagwira ntchito yofunika kwambiri pakuwongolera magawo a extrusion, monga kugawa kwa kutentha, kutuluka kwachitsulo, ndi kuzizira. Zinthu izi zimakhudza miyeso yomaliza ndi kulekerera kwa aluminiyamu extrusions.

6.Extrusion liwiro: Extrusion liwiro amakhudza tolerances a aluminiyamu extrusion ndi kulimbikitsa mlingo kuzirala ndi zitsulo otaya, zomwe zingachititse kusiyanasiyana miyeso ndi kulolerana kwa chomaliza mankhwala.

7, Kuzizira: Kuzizira kumakhudza kulolerana kwa aluminiyamu extrusion powongolera kuchuluka kwa kulimba, komwe kumakhudza kukhazikika kwapang'onopang'ono komanso kusasinthika kwa mawonekedwe, kukula, ndi kulekerera kwa chinthu chomaliza.

Ponseponse, kumvetsetsa ndi kulingalira zotsatira za zigawo za alloy, zinthu za mankhwala, kutentha ndi njira zoziziritsa panthawi ya aluminiyamu extrusion ndondomeko ndizofunikira kuti tikwaniritse kulekerera kolondola muzolemba zomaliza. Ngati mukufuna kudziwa zambiri za aluminiyamu extrusion, omasukaLumikizanani nafe.
