IkhayaI-Aluminium Extrusion
Aziwa nangokuthi amaphrofayili e-aluminium, amajamo amade, aqinile akhiqizwa ngenqubo ye-aluminium extrusion. Le nqubo ihlanganisa ukusunduza i-billet eshisiwe ye-aluminium ibe yifa lokufa, okudala amaphrofayili ahlukene ahlukene.
Lawa maphrofayili asetshenziswa kakhulu ezimbonini eziningi ngenxa yokuguquguquka kwawo, ukuqina kanye nokusebenza kahle kwezindleko.
Iqala ngokushisisa i-billet ye-aluminium ezingeni lokushisa elithile. Lokhu kwenza insimbi ibe lula futhi ifanelekele ukukhishwa. I-heated blank isuke iphushwa kumshini wokudayela oklanywe ngokukhethekile kusetshenziswa umshini wokucindezela we-hydraulic noma ipunch. Isikhunta sinikeza i-aluminium extrusion umumo oyifunayo kanye nephrofayili ye-cross-sectional. Ngemuva kokukhishwa, iphrofayili isikwa ubude obudingekayo futhi ingase ibhekane nezinqubo ezengeziwe ezifana nokwelashwa kwendawo noma ukukhanda.
Okokuqala, banesilinganiso esihle kakhulu samandla nesisindo, okubenza bangasindi kodwa babe namandla. Lokhu kuzenza zilungele izinhlelo zokusebenza lapho ukuncishiswa kwesisindo kubaluleke kakhulu, njengasezimbonini zezimoto nezasemoyeni. Okwesibili, inqubo ye-extrusion ingakha izimo eziyinkimbinkimbi kanye nemiklamo eyinkimbinkimbi. Lokhu kuvumelana nezimo kuvumela ukukhiqizwa kwamaphrofayela enziwe ngokwezifiso ahlangabezana nezidingo ezithile zohlelo lokusebenza. Okwesithathu, amaphrofayili e-aluminium anokumelana nokugqwala okuphezulu, okubavumela ukuthi bamelane nezindawo ezinokhahlo ngaphandle kokuphazamisa ubuqotho bawo besakhiwo. Ukwengeza, i-aluminiyamu ikwazi ukuphinda isetshenziswe kabusha, okwenza kube ukukhetha okuvumelana nemvelo.
Emkhakheni wokwakha, lawa maphrofayili asetshenziswa kumafreyimu amafasitela, izindonga zamakhethini kanye nezingxenye zesakhiwo. Ukumelana nokugqwala kwabo, isisindo esilula kanye nobuhle kubenza bafaneleke ezinhlelweni zokwakha. Embonini yezimoto, amaphrofayili e-aluminium asetshenziswa ezingxenyeni ze-chassis, ukushintshanisa ukushisa namaphaneli omzimba. Amandla azo, isisindo esilula kanye ne-thermal conductivity kuzenza zilungele ukuthuthukisa ukusebenza kahle kukaphethiloli kanye nokunciphisa ukukhishwa kwekhabhoni. Ukwengeza, imboni kagesi isebenzisa ama-aluminium extrusions kumasinki okushisa, izibani ze-LED, nezivalo zikagesi ngenxa yokushisa kwazo okuhle kakhulu. Ezinye izimboni ezifana nezokuthutha, imishini nezimpahla zabathengi nazo ziyazuza ekusebenziseni amaphrofayili e-aluminium.
Amaphrofayili e-aluminium asetshenziswa kakhulu ezimbonini ezahlukahlukene ngenxa yokuguquguquka kwawo, ukuqina, kanye nezakhiwo ezingasindi. Angatholakala ekwakhiweni, kwezokuthutha, kwezogesi, nakwezinye izinhlelo zokusebenza eziningi. Ngenkathi i-aluminium ngokwayo inokumelana nokugqwala kanye nendawo ebushelelezi, ukwelashwa okungaphezulu kuvame ukusetshenziswa ukuze kuthuthukiswe ukubukeka kwayo nezakhiwo zayo. Ezinye izindlela zokwelapha ezivamile zamaphrofayili e-aluminium zihlanganisa:
I-Mill finish: okuwumbala wokuqala we-aluminium ingxubevange ephuma ngqo ku-extruder. Okusho ukuthi awudingi ukwelashwa okungaphezulu.
I-Anodizing: I-Anodizing iyinqubo ye-electrochemical eyenza ungqimba lwe-oxide oluvikelayo endaweni ye-aluminium, okuholela ekwenyukeni kokumelana nokugqwala nobulukhuni. Iphinde ivumele izinketho zombala futhi ithuthukise ukukhanga kobuhle be-aluminium.
I-Powder coating: Ukumboza ngempushana kuhlanganisa ukufaka impuphu eyomile enamathela endaweni ye-aluminium electrostatic. Amaphrofayili amboziwe abe ephulukiswa kuhhavini, okuholela ekuqedeni okuqinile nokukhangayo. I-Powder coating inikeza isivikelo esihle kakhulu esimweni sezulu, emisebeni ye-UV, nokuhuzuka.
Ukupholisha: Ukupholisha kuyinqubo yemishini eyenza indawo ebushelelezi futhi ecwebezelayo kumaphrofayili e-aluminium. Ithuthukisa ukubukeka kwamaphrofayili futhi ibanikeze isiphetho esifana nesibuko.
Ukuxubha: Ukuxubha kuyindlela yokwelapha engaphezulu eyenza amaphethini ebhulashi aqondile noma ayindilinga kumaphrofayela e-aluminium. Inganikeza ukubukeka kwesimanje nesitayela kumaphrofayili futhi ivame ukusetshenziswa ezinhlelweni zezakhiwo.
I-Electrophoresis: I-Electrophoresis iyinqubo yokuhlanganisa i-electrochemical eqinisekisa isiphetho esifana nesandulela ukugqwala kumaphrofayili e-aluminium. Inikeza ukunamathela okuhle futhi ithuthukisa ukuqina kwamaphrofayili kanye nokumelana nesimo sezulu.
Amaphrofayili e-aluminium angenziwa kusetshenziswa amamaki e-aluminium alloy ahlukahlukene, ngalinye linezici zalo ezihlukile. Amanye amamaki e-aluminium alloy asetshenziswa kakhulu kumaphrofayili afaka:
6063: Leli yibanga elivame kakhulu le-aluminium alloy elisetshenziselwa amaphrofayili. Inikeza i-extrudability enhle, ukumelana nokugqwala, nokuqedwa kwendawo. Isetshenziswa kabanzi ezinhlelweni zezakhiwo, njengamafreyimu amafasitela, amafreyimu eminyango, nezindonga zamakhethini.
6061: I-alloy enamandla amakhulu ekwazi ukusebenza kahle kakhulu kanye nokumelana nokugqwala okuhle. Ithola izinhlelo zokusebenza ezingxenyeni zasolwandle, izingxenye zesakhiwo, nezimboni zezokuthutha.
6082: Yaziwa ngamandla ayo akhethekile kanye nokumelana nokugqwala, ingxubevange engu-6082 ivamise ukusetshenziswa ezinhlelweni zesakhiwo nezokuthutha, njengamabhuloho, ama-trusses, nezingxenye zezimoto.
6005: Le alloy ine-extrudability enhle namandla. Ivamise ukukhethelwa amaphrofayili adinga ukwenziwa kwemishini okujulile, okufana namasinki okushisa kanye nezivalo zikagesi.
7005: Kuyingxubevange yamandla aphezulu enokuqina okuhle. Ilungele izinhlelo zokusebenza ezidinga ubuqotho obuphezulu besakhiwo, njengamafreyimu amabhayisikili, izingxenye zezimoto, nemishini yezemidlalo.
Lezi izibonelo ezimbalwa nje zamamaki e-aluminium alloy amaningi atholakalayo ukukhiqiza amaphrofayili. Ukukhethwa kwebanga le-alloy kuncike ezidingweni ezithile zohlelo lokusebenza, okuhlanganisa amandla, ukumelana nokugqwala, ukunwebeka, nokuqedwa kwendawo.
