Inqubo ye-Aluminium Extrusion

I-Extrusion ichazwa njengenqubo yokubumba impahla, efana ne-aluminium, ngokuyiphoqa ukuthi igeleze ngembobo emise okudayizini.Izinto ezinwetshiwe zivela njengesiqephu eside esinephrofayili efanayo nokuvula idayizi.

Isici esibaluleke kakhulu okufanele sikhumbule enqubweni ye-extrusion izinga lokushisa.Izinga lokushisa libaluleke kakhulu ngoba linikeza i-aluminium izici ezifiselekayo ezinjengokuqina nokuqeda.

Izinyathelo zenqubo ye-aluminium extrusion

1.Amabhilidi kufanele ashiselwe cishe ku-800-925° F.

2.Ngemva kokuba i-billet ifinyelele izinga lokushisa elifunayo, lidluliselwa ku-loader lapho ifilimu encane ye-smut noma i-lubricant yengezwe ku-billet kanye nenqama.I-smut isebenza njenge-ejenti ehlukanisayo (i-lubricant) egcina izingxenye ezimbili zinganamathelani.

3.I-billet idluliselwa kumbeleko.

4.Inqama icindezela i-dummy block, yona, iphusha i-billet ize ibe ngaphakathi esitsheni.

5.Ngaphansi kwengcindezi i-billet igaywa ngokufa, iba mfushane futhi ibe banzi ize ihlangane ngokugcwele nezindonga zesitsha.Ngenkathi i-aluminiyamu iphushwa ku-dies, i-nitrogen eyi-liquid igeleza izungeze izingxenye ezithile zefa ukuze ipholise.Lokhu kukhulisa impilo ye-die futhi kudala umoya ongasebenzi ogcina ama-oxide angakheki kumumo okhishwayo.Kwezinye izimo igesi ye-nitrogen isetshenziswa esikhundleni se-nitrogen ewuketshezi.Igesi ye-nitrogen ayipholi i-die kodwa yakha umoya ongasebenzi.6.Ngenxa yokucindezela okwengezwe ku-billet, insimbi ethambile kodwa eqinile iqala ukukhama ngembobo yokufa.

7.Njengoba i-extrusion iphuma emshinini wokunyathelisa, izinga lokushisa lithathwa ngethuluzi le-True Temperature Technology (3T) elifakwe epuletini lokucindezela.I-3T irekhoda izinga lokushisa lokuphuma kwe-aluminium extrusion.Inhloso enkulu yokwazi izinga lokushisa ukugcina isivinini esikhulu sokucindezela.Izinga lokushisa eliqondiwe lokuphuma kwe-extrusion lincike kungxubevange.Isibonelo, izinga lokushisa eliqondiwe lokuphuma kuma-alloys 6063, 6463, 6063A, kanye no-6101 lingu-930° F (okungenani).Izinga lokushisa eliqondiwe lokuphuma kuma-alloys 6005A, kanye no-6061 lingu-950° F (okungenani).

8.Ama-Extrusions aphushwa ngaphandle kwefa kuya etafuleni eliphumayo kanye nomdonsa, oqondisa insimbi phansi kwetafula eliphumayo ngesikhathi sokukhipha.Ngenkathi idonswa, i-extrusion ipholiswa uchungechunge lwabalandeli kulo lonke ubude betafula lokuphuma nokupholisa.(Qaphela: Ingxubevange 6061 amanzi acinywa kanjalo nomoya ucishiwe.)

9.Akuwona wonke ama-billet angasetshenziswa.Okusele (i-butt) kuqukethe ama-oxide avela esikhumbeni se-billet.I-butt iyagundwa futhi ilahlwe ngenkathi enye i-billet ilayishwa futhi ishiselwe ku-billet elayishwe ngaphambilini futhi inqubo yokukhipha iyaqhubeka.Lapho i-extrusion ifinyelela ubude obufunekayo, i-extrusion inqunywa ngesaha yephrofayili noma i-shear.

10.Insimbi idluliswa (ngebhande noma amasistimu emishayo yokuhamba) isuka etafuleni eliphumayo iye etafuleni lokupholisa.

11.Ngemva kokuba i-aluminiyamu isipholile futhi ihamba eduze kwetafula lokupholisa, isuke ihanjiswa kuhlaka.Ukwelula kuqondisa ama-extrusions futhi kwenze 'ukuqina komsebenzi' (ukuqondanisa kabusha kwamangqamuzana okunikeza i-aluminium ubulukhuni obuningi namandla athuthukisiwe).

12.Isinyathelo esilandelayo wukusaha.Ngemuva kokuthi ama-extrusions eluliwe adluliselwa etafuleni le-saw futhi anqunywe ubude obuthile.Ukubekezelela ukusika kumasaha kungu-1/8 intshi noma ngaphezulu, kuye ngobude besaha.

Ngemva kokuba izingxenye sezisikiwe, zilayishwa emshinini wokuthutha bese ziyiswa kumahhavini amadala.Ukwelapha ukushisa noma ukuguga okwenziwayo kwenza insimbi ibe lukhuni ngokusheshisa inqubo yokuguga endaweni yokushisa elawulwayo isikhathi esimisiwe.
