Aluminum Extrusions

Extrusionshi ne tsarin da ake iya samar da sassan ƙarfe madaidaiciya madaidaiciya.Sassan giciye waɗanda za a iya samarwa sun bambanta daga ƙaƙƙarfan zagaye, rectangular, zuwa sifofin L, Siffofin T.Tubes da sauran nau'ikan iri daban-daban.Ana yin extrusion ta hanyar matse ƙarfe a cikin rufaffiyar rami ta hanyar kayan aiki, wanda aka sani da mutuwa ta amfani da injin inji ko na'ura mai aiki da karfin ruwa.

Extrusion yana haifar da ƙarfi da ƙarfi a cikin hannun jari.Ba a samar da ƙwanƙwasa ba, wanda ke sa babban nakasu zai yiwu ba tare da yaga ƙarfe ba.Ramin da ɗanyen kayan ke ƙunshe an lulluɓe shi da wani abu mai jurewa lalacewa.Wannan zai iya tsayayya da babban nauyin radial wanda aka halicce shi lokacin da aka tura kayan ya mutu.

Extrusions, sau da yawa rage buƙatar injiniyoyi na biyu, amma ba daidai ba ne na girman girman ko gamawar saman kamar sassan injina.Ƙarshen saman don karfe shine 3um;(125 uin), da Aluminum da Magnesium ne 0.8 um (30 uin).Duk da haka, wannan tsari zai iya samar da nau'i-nau'i iri-iri masu yawa waɗanda ke da wuyar samar da farashi mai mahimmanci ta amfani da wasu hanyoyi.Mafi ƙarancin kauri na karfe shine kusan mm 3 (0.120 in), yayin da Aluminum da Magnesium kusan 1mm (0.040 in).Mafi ƙarancin sassan giciye sune 250 mm2 (0.4 in2) don ƙarfe kuma ƙasa da waccan don Aluminum da Magnesium.Ƙananan kusurwa da fillet radius sune 0.4 mm (0.015 in) don Aluminum da Magnesium, kuma don karfe, ƙananan radius na kusurwa shine 0.8mm (0.030 a) da 4 mm (0.120 a) fillet radius.

Ciwon sanyi:Sanyi extrusion shine tsari da ake yi a cikin ɗaki da zafin jiki ko kuma ɗanɗano mai girman zafi.Ana iya amfani da wannan tsari don yawancin kayan aiki-batun zayyana isassun kayan aiki masu ƙarfi waɗanda zasu iya jure matsalolin da aka haifar ta hanyar extrusion.Misalai na karafa da za a iya fitar da su sune gubar, tin, aluminum gami, jan karfe, titanium, molybdenum, vanadium, karfe.Misalan sassan da aka fitar da sanyi sune bututun da za a iya rugujewa, gwangwani na aluminium, silinda, abubuwan gear.Amfanin sanyi extrusion sune:

• * Babu oxidation faruwa
• *Kyawawan kaddarorin inji saboda tsananin sanyi yana aiki muddin yanayin yanayin da aka ƙirƙira yana ƙasa da yanayin sake-crystallization
• *Kyakkyawan gamawa tare da yin amfani da man shafawa masu dacewa

Extrusion mai zafi:Ana yin extrusion mai zafi a yanayin zafi mai kyau, kusan 50 zuwa 75% na wurin narkewar ƙarfe.Matsalolin na iya bambanta daga 35-700 MPa (5076 - 101,525 psi).Saboda yanayin zafi da matsa lamba da kuma mummunan tasirinsa a kan rayuwar mutuwa da sauran abubuwan da aka gyara, mai kyau mai kyau ya zama dole.Man fetur da graphite suna aiki a ƙananan yanayin zafi, yayin da a yanayin zafi mafi girma ana amfani da foda gilashi.

Abubuwan da aka saba samarwa ta hanyar extrusions sune sassan datsa da ake amfani da su a cikin kera motoci da aikace-aikacen gini, membobin firam ɗin taga, dogo, sassan tsarin jirgin sama.
