Inkqubo yeAluminiyam Extrusion

I-Extrusion ichazwa njengenkqubo yokubunjwa kwezinto, ezifana ne-aluminium, ngokuyinyanzela ukuba ihambe ngembobo emile kwi-die.Izinto ezongeziweyo ziphuma njengeqhekeza elide kunye neprofayili efanayo kunye nokuvulwa kwefa.

Eyona nto ibalulekileyo ekufuneka uyikhumbule kwinkqubo ye-extrusion yiqondo lokushisa.Ubushushu bubaluleke kakhulu kuba inika ialuminiyam iimpawu ezinqwenelekayo ezinjengokuqina kunye nokugqiba.

Amanyathelo kwinkqubo ye-aluminium extrusion

1.Iibhilithi kufuneka zifudunyezwe malunga ne-800-925° F.

2.Emva kokuba i-billet ifikelele kwiqondo lokushisa elifunwayo, idluliselwa kwi-loader apho ifilimu encinci ye-smut okanye i-lubricant yongezwa kwi-billet kunye nenkunzi yegusha.I-smut isebenza njenge-agent yokwahlula (i-lubricant) egcina la malungu mabini angabambeleli kunye.

3.I-billet idluliselwa kwi-cradle.

4.Inkunzi yegusha ifaka uxinzelelo kwibloko yedummy ethi, yona, ityhale ibhilethi ide ibe ngaphakathi kwesikhongozeli.

5.Ngaphantsi koxinzelelo ibhilethi iyatyunyuzwa kwidayizi, ibe mfutshane kwaye ibe banzi de idibane ngokupheleleyo neendonga zesikhongozeli.Ngelixa i-aluminiyam ityhalwa ngokufa, initrogen engamanzi iqukuqela ijikeleze amanye amacandelo efa ukuze ipholise.Oku kwandisa ubomi bokufa kwaye kudala umoya ongasebenziyo ogcina iioksidi zingabikho kwimilo ekhutshiweyo.Kwezinye iimeko igesi yenitrogen isetyenziswa endaweni yenitrogen engamanzi.Igesi ye-nitrojeni ayipholisi i-die kodwa idala umoya ongasebenziyo.

I-7.Njengoko i-extrusion iphuma kwi-press, iqondo lokushisa lithathwa nge-True Temperature Technology (3T) isixhobo esifakwe kwi-press platen.Iirekhodi ze-3T zokuphuma kobushushu be-aluminium extrusion.Injongo ephambili yokwazi ubushushu kukugcina isantya esiphezulu sokushicilela.Iqondo lobushushu ekujoliswe kulo kwi-extrusion lixhomekeke kwi-alloy.Ngokomzekelo, iqondo lokushisa ekujoliswe kulo kwi-alloys 6063, 6463, 6063A, kunye ne-6101 yi-930 ° F (ubuncinci).Iqondo lokushisa ekujoliswe kulo kwi-alloys 6005A, kunye ne-6061 yi-950 ° F (ubuncinci).

I-8.I-Extrusions ikhutshwe kwi-die ukuya kwitheyibhile ehamba phambili kunye ne-draller, ekhokela isinyithi phantsi kwetafile ephumayo ngexesha lokukhupha.Ngelixa litsalwa, i-extrusion ipholile ngokulandelelana kwabalandeli kunye nobude bonke betafile yokuqhuba kunye nokupholisa.(Qaphela: I-alloy 6061 ngamanzi acinyiweyo kunye nomoya ocinyiweyo.)

9.Ayiyiyo yonke i-billet enokusetyenziswa.Intsalela (impundu) iqulethe iioksidi ezivela kwisikhumba sebillet.I-butt inqunyulwe kwaye ilahlwe ngelixa enye i-billet ilayishwa kwaye idityaniswe kwi-billet elayishiwe ngaphambili kwaye inkqubo ye-extrusion iyaqhubeka.Xa i-extrusion ifikelela kubude obufunwayo, i-extrusion inqunywe nge-profile saw okanye i-shear.

I-10.Intsimbi idluliswa (ngebhanti okanye kwiinkqubo zemiqadi yokuhamba) ukusuka kwitheyibhile yokukhupha ukuya kwitafile yokupholisa.

11.Emva kokuba i-aluminiyam ipholile kwaye ihamba ecaleni kwetafile yokupholisa, emva koko ihanjiswe kwi-stretcher.Ukolula kulungelelanisa i-extrusions kwaye kwenza 'ukuqina komsebenzi' (ukulungelelaniswa kwakhona kwemolekyuli okunika i-aluminiyam eyandisiweyo yobulukhuni kunye namandla aphuculweyo).

12.Inyathelo elilandelayo kukusarha.Emva kokuba i-extrusions yoluliwe idluliselwa kwitafile ye-saw kwaye inqunywe ubude obuthile.Ukunyamezela ukusika kwiisarha yi-1/8 intshi okanye ngaphezulu, kuxhomekeke kubude besarha.

Emva kokuba iinxalenye zisikiwe, zilayishwa kwisixhobo sokuthutha kwaye zihanjiswe kwii-ovens zeminyaka.Ukushisa-ukushisa okanye ukuguga okwenziwe lukhuni isinyithi ngokukhawulezisa inkqubo yokuguga kwindawo yokushisa elawulwayo kwixesha elimiselweyo.
