Iityhubhu ze-aluminiyam ezongeziweyo ziyinxalenye ebalulekileyo kumashishini ahlukeneyo, ukusuka kwi-aerospace ukuya kulwakhiwo. Ubunzima babo obukhaphukhaphu, amandla aphezulu, kunye nokumelana nomhlwa kubenza babe yinto efanelekileyo kwizicelo apho ukusebenza kubaluleke kakhulu. Ukuphucula ukusebenza kweetyhubhu ze-aluminiyam ezikhutshiweyo kufuna ukuqwalaselwa ngenyameko kwizinto ezininzi ezibalulekileyo, kubandakanywa ukukhethwa kwezinto eziphathekayo, inkqubo ye-extrusion, kunye nonyango lwasemva kokulungiswa.
Ukukhetha i-aluminium alloy ibalulekile ekufezekiseni iimpawu zokusebenza ezifunekayo. Ii-alloys ezahlukeneyo zinika indibaniselwano eyodwa yamandla, i-ductility, ukuxhathisa ukubola, kunye ne-weldability. Ama-alloys aqhelekileyo asetyenziselwa iityhubhu ze-aluminium extruded ziquka i-6061, i-6063, kunye ne-7075. Ukukhetha i-alloy efanelekileyo kuxhomekeke kwiimfuno ezithile zesicelo.
Inkqubo ye-extrusion ibandakanya ukunyanzeliswa kwe-aluminiyam etyhidiweyo ngokufa ukudala imilo efunekayo. Ukulawula iiparamitha ze-extrusion, ezifana neqondo lokushisa, uxinzelelo, kunye nesantya, kubalulekile ekuphuculeni iimpawu zomatshini wetyhubhu. I-extrusion engafanelekanga inokukhokelela kwiziphene, ezifana nokungafezeki kwendawo, i-porosity yangaphakathi, kunye nesakhiwo sengqolowa esingalinganiyo, esinokuphazamisa ukusebenza.
Unyango lwasemva kokulungiswa lunokuphucula ngakumbi ukusebenza kweetyhubhu ze-aluminium ezikhutshiweyo. I-Anealing iphucula i-ductility, ngelixa ukuguga kwandisa amandla kunye nobunzima. Ezi nkqubo ziphucula i-microstructure ye-tube kwaye zilungelelanise iimpawu zayo zomatshini ukuhlangabezana neemfuno ezithile zesicelo. Ukongeza, unyango olungaphezulu, olufana ne-anodizing okanye i-powder coating, lunokuphucula ukuxhathisa kwe-corrosion kunye ne-aesthetics.
Ubunzima bodonga lombhobho budlala indima ebalulekileyo kwingqibelelo yesakhiwo. Iindonga ezityebileyo zinika amandla aphezulu kodwa zonyusa ubunzima. Ukumisela ubukhulu bodonga olufanelekileyo kufuna ukulinganisa iimfuno zesakhiwo kunye nokuqwalaselwa kobunzima. Ubukhulu bodonga bunokwahluka ngobude betyhubhu ukwenza iimilo zesiko kunye nokwandisa ukusebenza.
Ukuchaneka komda kubalulekile ekuqinisekiseni ukufaneleka nokusebenza ngokufanelekileyo. Iityhubhu ze-aluminiyam ezongeziweyo zinokuvezwa ngokuchanekileyo ukuhlangabezana nokunyamezela okuqinileyo, ukuqinisekisa ukulungelelaniswa okuchanekileyo kunye nokuhambelana namanye amacandelo. Ubuchwephesha obuphezulu be-extrusion, obufana ne-multi-axis extrusion, yenza ukuba ukuveliswa kweemilo eziyinkimbinkimbi kunye nokuchaneka okuphezulu kwe-dimensional.
Ukugqitywa komphezulu wetyhubhu kuchaphazela ubuhle bayo, ukuxhathisa ukubola, kunye neempawu zokushisa. Iinkqubo ze-Extrusion zinokuvelisa iityhubhu ezinomphezulu ohlukeneyo ogqityiweyo, ukusuka kumtyibilizi kunye nopolishiweyo ukuya kwi-textured okanye ipateni. Unyango lwasemva kokulungiswa, olufana nokusila, ukuxukuxa, okanye ukupolisha, kunokuphucula ngakumbi umphezulu wokugqiba.
Ukuphucula ukusebenza ngeetyhubhu ze-aluminium ezikhutshiweyo kufuna indlela ebanzi eqwalasela ukukhethwa kwezinto, inkqubo ye-extrusion, unyango lwe-post-processing, ubukhulu bodonga, ukuchaneka kobukhulu, kunye nokugqitywa komphezulu. Ngokulungelelanisa ngononophelo ezi zinto, iinjineli zinokwenza iityhubhu ze-aluminium ezikhutshiweyo ezihlangabezana neemfuno ezifunwayo zezicelo ezahlukeneyo, ziqinisekisa ukusebenza okubalaseleyo kunye nokuphila ixesha elide.
