1. Ka'idar extrusion aluminum

Extrusion hanya ce ta sarrafa extruding wacce ke sanya ƙarfin waje akan billet ɗin ƙarfe a cikin akwati (extrusion cylinder) kuma yana sanya shi gudana daga wani takamaiman rami mai mutu don samun siffar sashin da ake so da girman.

2. The bangaren na aluminum extruder

The extruder hada da firam, gaban ginshiƙi frame, fadada shafi, extrusion Silinda, na'ura mai aiki da karfin ruwa tsarin karkashin ikon lantarki, da kuma sanye take da mold tushe, thimble, sikelin farantin, slide farantin da sauransu.

3. Rarraba hanyar extrusion aluminum

Dangane da nau'in karfe a cikin silinda extrusion: Jagoran damuwa da yanayin damuwa, extrusion, yanayin lubricating, zafin jiki na extrusion, saurin extrusion, ko nau'ikan tsarin ci gaba, siffar da babu.na blank ko na samfurin nau'in, za a iya raba zuwa m extrusion, baya extrusion, (ciki har da jirgin sama iri extrusion, axisymmetric nakasawa extrusion, general uku-girma nakasawa extrusion) a kaikaice extrusion, gilashin lubricating extrusion, Hydrostatic extrusion, m extrusion da sauransu. kan.

4. Gaba da thermal nakasawa na aluminum extrusion

Yawancin kamfanonin samar da nakasar aluminium masu zafi suna ɗaukar hanyar haɓaka zafin nakasar gaba ta hanyar takamaiman mutu (lebur, mutuƙar mazugi, shunt mutu) don samun daidaitattun bayanan martaba na aluminum tare da sashin da ake so da siffa.

Tsarin extrusion na gaba yana da sauƙi, kayan buƙatun kayan aiki ba su da yawa, ƙarfin nakasar ƙarfe yana da girma, kewayon samarwa yana da faɗi, aikin aluminum yana da iko, samar da sassaucin ra'ayi yana da girma, kuma ƙirar yana da sauƙi don kulawa da sake dubawa.

Lalacewar yana tare da gogayya mai zurfi daga bututun extrusion na aluminium na ciki, yawan amfani da makamashi yana da girma, juzu'i na Silinda yana da sauƙin yin zafin simintin, da haɓaka rashin daidaituwa na bayanan martaba, rage haɓakar samfuran gamawa, iyakance saurin aluminium da aluminium gami da haɓaka, haɓakawa. lalacewa da rayuwar sabis na extrusion mutu, samfurori marasa daidaituwa.

5. Nau'in zafi nakasar aluminum gami, aiki da amfani

Nau'in zafi nakasawa aluminum gami an kasu kashi 8 Categories bisa ga yi da aikace-aikace, su yi da kuma amfani ne daban-daban:

1) Pure aluminum (L series) m da kasa da kasa iri 1000 jerin tsarki aluminum.

Aluminum mai tsabta na masana'antu, ingantaccen machinability, juriya na lalata, tare da jiyya na ƙasa da ƙarancin wutar lantarki, amma ƙarancin ƙarfi, ana amfani dashi a cikin kayan gida, samfuran lantarki, magunguna da kayan abinci, watsawa da kayan rarrabawa, da sauransu.

2) Duralumin (Ly) yayi daidai da alamar kasa da kasa 2000 Al-Cu (Aluminum-Copper) gami.

An yi amfani da shi a cikin manyan abubuwa, tallafi, babban abun ciki na Cu, rashin juriyar lalata.

3) Rust-proof aluminum (LF) daidai da alamar kasa da kasa 3000 Al-Mn (aluminum manganese) gami.

Ba a ƙarfafa maganin zafi ba, kayan aiki, juriya na lalata da aluminum mai tsabta, an inganta ƙarfin aiki, aikin walda mai kyau, ana amfani da shi sosai a cikin buƙatun yau da kullum, kayan gini, na'urori da sauran abubuwa.

4) Aluminum na musamman (LT) wanda ya dace da alamar kasa da kasa 4000 Al-Si gami.

Yafi kayan walda, ƙarancin narkewa (digiri 575-630), ruwa mai kyau.

5) Anti-tsatsa aluminum (LF) daidai da alamar kasa da kasa 5000Al-Mg (aluminum da magnesium) gami.

Ba a ƙarfafa maganin zafi ba, juriya na lalata, weldability, kyakkyawan haske mai kyau, ta hanyar sarrafa abun ciki na Mg, na iya samun matakan ƙarfin daban-daban na gami.Ƙananan matakin don kayan ado, na'urori masu tasowa;Matsakaicin matakin jiragen ruwa, motoci, kayan gini;Babban matakin da ake amfani da shi don abubuwan walda a cikin tsire-tsire masu guba na jiragen ruwa da abubuwan hawa.

6) 6000 Al-Mg-Si gami.

Mg2Si hazo hardening zafi magani iya ƙarfafa gami, mai kyau lalata juriya, matsakaici ƙarfi, m thermal workability, don haka shi ne yadu amfani da extrusion abu, mai kyau formability, high taurin za a iya samu ta quenching.Ana amfani dashi sosai a cikin ginin bayanan martaba kuma shine babban tushen kayan aiki a masana'antu.

7) Superhard aluminum (LC) yayi dace da alamar duniya 7000Al-Zn-Mg-Cu (Al-Zn-Mg-Cu) mai ƙarfi aluminum gami da Al-Zn-Mg gami da aka yi amfani da su don abubuwan walda, waɗanda ke da ƙarfi mai ƙarfi, kyakyawan walda da aikin kashewa, amma lalatawar danniya da juriya, wanda ke buƙatar haɓaka ta hanyar maganin zafi mai dacewa.Na farko dai ana amfani da shi ne don jiragen sama da kayayyakin wasanni, yayin da na biyun kuma ana amfani da shi ne wajen walda kayan aikin motocin jirgin kasa.

8) 8000 (Al-Li) Aluminum-lithium gami.

Babban halayyar shi ne cewa yawa ne 8% -9% kasa da 7000-jerin, high rigidity, high ƙarfi, haske nauyi, wannan jerin ne a karkashin ci gaba (da anti-lalata ikon aluminum gami karfe a karkashin hadaddun yanayi ba a gaba daya cinye. ), galibi ana amfani da su a cikin jiragen sama, makamai masu linzami, injuna da sauran aikace-aikacen soja.
