Izindaba

1. Isimiso se-aluminium extrusion

I-Extrusion iyindlela yokucubungula ekhipha amandla angaphandle ebeka amandla angaphandle ku-billet yensimbi esitsheni (isilinda sokukhipha) futhi iyenze igeleze iphume emgodini othize wokufa ukuze ithole ukwakheka kwesigaba esifiselekayo nosayizi.

2. Ingxenye ye-aluminium extruder

I-extruder yakhiwe ngohlaka, uhlaka lwekholomu yangaphambili, ikholomu yokwandisa, isilinda sokukhipha, isistimu ye-hydraulic ngaphansi kokulawulwa kukagesi, futhi ifakwe isisekelo sesikhunta, i-thimble, ipuleti lesikali, ipuleti lesilayidi nokunye.

3. Ukuhlukaniswa kwendlela ye-aluminium extrusion

Ngokohlobo lwensimbi kusilinda sokukhipha: Isiqondiso sokucindezeleka nesimo sokucindezeleka, i-extrusion, isimo sokugcoba, izinga lokushisa lokukhipha, isivinini sokukhipha, noma izinhlobo zesakhiwo esithuthukisiwe, umumo kanye no-cha.engenalutho noma yohlobo lomkhiqizo, ingahlukaniswa ibe yi-extrusion enhle, i-extrusion eya emuva, (kufaka phakathi i-extrusion yendiza, i-axisymmetric deformation extrusion, i-general three-dimensional deformation extrusion) i-lateral extrusion, i-glass lubricating extrusion, i-Hydrostatic extrusion, i-extrusion eqhubekayo nokunye. ku.

4. Phambili ukuguqulwa okushisayo kwe-aluminium extrusion

Iningi lamabhizinisi akhiqiza i-aluminium eshintshashintshayo eshisayo asebenzisa indlela ye-extrusion ye-hot deformation extrusion ngokusebenzisa ukufa okuthile (flat die, cone die, shunt die) ukuze athole amaphrofayili e-aluminium angaguquki anesigaba nesimo esifiselekayo.

Inqubo ye-extrusion eya phambili ilula, izidingo zemishini aziphezulu, ikhono lokuguqulwa kwensimbi liphezulu, uhla lokukhiqiza lubanzi, ukusebenza kwe-aluminium kuyalawuleka, ukuguquguquka kokukhiqiza kukhulu, futhi isikhunta kulula ukusigcina nokuyibuyekeza.

Isici sihambisana nokungqubuzana kwendawo ephuma kushubhu ye-aluminium extrusion yangaphakathi, ukusetshenziswa kwamandla kuphezulu, isilinda sokungqubuzana kulula ukwenza ukushisa okukhiphayo, futhi kwandise ukungazinzi kwamaphrofayili, kunciphise ukusebenza kahle komkhiqizo wokuqeda, kukhawulele isivinini se-aluminium ne-aluminium alloy extrusion, kuyashesha ukugqoka nempilo yesevisi ye-extrusion iyafa, imikhiqizo engalingani.

5. Uhlobo lwe-hot deformation aluminium alloy, ukusebenza nokusetshenziswa

Izinhlobo ze-hot deformation aluminium alloy zihlukaniswe ngezigaba eziyi-8 ngokuya ngokusebenza nezinhlelo zokusebenza, ukusebenza kwazo nokusetshenziswa kwazo kuhlukile:

1) I-aluminium ehlanzekile (uchungechunge lwe-L) oluhambisana nochungechunge lwamazwe ngamazwe lwe-1000 ye-aluminium ehlanzekile.

I-aluminium ehlanzekile yezimboni, i-machinability enhle kakhulu, ukumelana nokugqwala, nokwelashwa kwendawo kanye nokusebenza kukagesi, kodwa amandla aphansi, asetshenziswa ezimpahleni zasendlini, imikhiqizo kagesi, imithi kanye nokupakishwa kokudla, izinto zokudlulisa nokusabalalisa, njll.

2) I-Duralumin (Ly) ihambisana nomkhiqizo wamazwe ngamazwe we-2000 Al-Cu (Aluminium-copper) alloy.

Isetshenziswa ezingxenyeni ezinkulu, izisekelo, okuqukethwe okuphezulu kwe-Cu, ukumelana nokugqwala okungekuhle.

3) I-aluminium evimbela ukugqwala (LF) ehambisana ne-alloy brand yamazwe ngamazwe engu-3000 Al-Mn (aluminium manganese).

Ukwelashwa kokushisa akuqiniswanga, umshini, ukumelana nokugqwala kanye ne-aluminium ehlanzekile, amandla athuthukisiwe, ukusebenza kahle kwe-welding, okusetshenziselwa kakhulu izidingo zansuku zonke, izinto zokwakha, amadivaysi nezinye izici.

4) I-Aluminium Ekhethekile (LT) ehambisana ne-alloy brand yamazwe ngamazwe engu-4000 Al-Si.

Ikakhulukazi impahla yokushisela, indawo encibilikayo ephansi (ama-575-630 degrees), i-fluidity enhle.

5) I-Anti-rust aluminium (LF) ehambisana ne-alloy brand yamazwe ngamazwe i-5000Al-Mg (i-aluminium ne-magnesium).

Ukwelashwa kokushisa akuqiniswa, ukumelana nokugqwala, ukushisela, isicwebezelisi sendawo enhle kakhulu, ngokulawulwa kokuqukethwe kwe-Mg, kungathola amazinga ahlukene wamandla we-alloy.Izinga eliphansi lezinto zokuhlobisa, amadivaysi athuthukile;Izinga elimaphakathi lemikhumbi, izimoto, izinto zokwakha;Izinga eliphezulu elisetshenziselwa izingxenye zokushisela ezitshalweni zamakhemikhali zemikhumbi nezimoto.

6) 6000Al-Mg-Si ingxubevange.

I-Mg2Si imvula eyenza lukhuni ukwelashwa kokushisa ingaqinisa ingxubevange, ukumelana nokugqwala okuhle, amandla amaphakathi, ukusebenza kahle kakhulu kokushisa, ngakho-ke isetshenziswa kabanzi njengempahla yokukhipha, ukwakheka okuhle, ubulukhuni obuphezulu bungatholwa ngokucisha.Isetshenziswa kabanzi ekwakheni amaphrofayili futhi ingumthombo wezinto ezibonakalayo embonini.

7) I-Superhard aluminium (LC) ihambisana nohlobo lwamazwe ngamazwe lwe-7000Al-Zn-Mg-Cu (Al-Zn-Mg-Cu) i-aluminium alloy enamandla amakhulu kanye ne-Al-Zn-Mg ingxubevange esetshenziselwa izingxenye zokushisela, ezinamandla amakhulu, ukusebenza kahle kakhulu kokushisela nokusebenza kokucisha, kodwa ukugqwala kwengcindezi okungekuhle kanye nokumelana nokuqhekeka, okudinga ukuthuthukiswa ngokwelashwa okufanele kokushisa.Eyangaphambili isetshenziselwa ikakhulukazi izindiza nezimpahla zezemidlalo, kanti lena yakamuva isetshenziselwa ukushisela izinto zokwakha zezimoto zikaloliwe.

8) 8000 (Al-Li) Ingxubevange ye-Aluminium-lithium.

Isici esikhulu kunazo zonke ukuthi ukuminyana kungama-8% -9% aphansi kune-7000-series, ukuqina okuphezulu, amandla aphezulu, isisindo esincane, lolu chungechunge lusathuthukiswa (ikhono lokulwa nokubola kwensimbi ye-aluminium alloy ngaphansi kwezimo eziyinkimbinkimbi alizange linqotshwe ngokuphelele. ), esetshenziswa kakhulu ezindizeni, ezicitshwayo, ezinjinini nakwezinye izinhlelo zempi.
