Aluminium Extrusions

Extrusionndiyo nzira iyo mativi akareba esimbi anogona kugadzirwa.Michinjikwa-zvikamu zvinogona kugadzirwa zvinosiyana kubva kutenderera kwakasimba, rectangular, kusvika kuL maumbirwo, T maumbirwo.Machubhu nemamwe marudzi mazhinji akasiyana.Kuwedzeredza kunoitwa nekudzvanya simbi mugomba rakavharika kuburikidza nemudziyo, unozivikanwa sefa uchishandisa kana mechanical kana hydraulic press.

Extrusion inogadzira compressive uye shear masimba mustock.Hapana tensile inogadzirwa, iyo inoita kuti deformation yakakwirira igoneke pasina kubvarura simbi.Iyo mhango umo iyo raw material irimo yakarongedzerwa nezvinhu zvinopfekwa.Izvi zvinogona kumirisana neyakakura radial mitoro inogadzirwa kana zvinhu zvinosundirwa kufa.

Extrusions, kazhinji inodzikisira kudiwa kwechipiri machining, asi isiri yeakaenzana dimensional kurongeka kana kupedzisa kwepamusoro sezvikamu zvemuchina.Surface kupera kwesimbi ndeye 3um;(125 uin), uye Aluminium neMagnesium i0.8 um (30 uin).Zvisinei, iyi nzira inogona kubereka zvakasiyana-siyana zve-cross-sections zvakaoma kuburitsa zvinodhura-zvinobudirira uchishandisa dzimwe nzira.Ukobvu hudiki hwesimbi hunosvika 3 mm (0.120 mukati), nepo Aluminium neMagnesium inenge 1mm (0.040 mukati).Minimum cross sections i250 mm2 (0.4 in2) yesimbi uye isingasviki iyo yeAluminium neMagnesium.Minimum corner uye fillet radii ndeye 0.4 mm (0.015 mu) yeAluminium neMagnesium, uye yesimbi, iyo shoma yekona radius i 0.8mm (0.030 mu) uye 4 mm (0.120 mu) fillet radius.

Cold Extrusion:Cold extrusion maitiro anoitwa pakamuri tembiricha kana tembiricha yakakwira zvishoma.Iyi nzira inogona kushandiswa kune zvakawanda zvekushandisa-zvichienderana nekugadzira yakasimba yakakwana tooling iyo inogona kumira kushushikana kunogadzirwa neextrusion.Mienzaniso yesimbi inogona kubudiswa mutobvu, tini, aruminiyamu alloys, mhangura, titanium, molybdenum, vanadium, simbi.Mienzaniso yezvikamu zvinotonhora zvakasimudzwa machubhu anodonha, magaba ealuminium, masilinda, magiya mabheji.Zvakanakira kutonhora extrusion ndezvi:

• * Hapana oxidation inoitika
• *Yakanaka michina zvivakwa nekuda kwekutonhora kwakanyanya kushanda chero tembiricha yakasikwa iri pazasi re-crystallization tembiricha
• *Kupera kwakanaka kwepamusoro nekushandiswa kwemafuta akakodzera

Hot Extrusion:Kupisa extrusion kunoitwa patembiricha yakakwira, ingangoita 50 kusvika 75% yekunyungudika kwesimbi.Izvo zvinodzvinyirira zvinogona kubva ku35-700 MPa (5076 - 101,525 psi).Nekuda kwekupisa kwakanyanya uye kumanikidza uye kukanganisa kwaro pahupenyu hwekufa pamwe nezvimwe zvinhu, mafuta akanaka anodiwa.Oiri uye graphite inoshanda patembiricha yakaderera, nepo patembiricha yepamusoro yegirazi poda inoshandiswa.

Zvakajairwa zvikamu zvinogadzirwa neextrusions zvikamu zvidiki zvinoshandiswa mumotokari uye zvikumbiro zvekuvaka, nhengo dzemahwindo, njanji, zvimiro zvendege.
