Iindaba

1. Umgaqo we-aluminium extrusion

I-Extrusion yindlela yokucubungula ekhuphayo ebeka amandla angaphandle kwi-billet yesinyithi kwi-container (i-extrusion cylinder) kwaye yenza ukuba iphume kumngxunya othile wokufa ukuze ifumane ubume becandelo elifunekayo kunye nobukhulu.

2. Icandelo le-aluminium extruder

I-extruder yenziwe ngesakhelo, isakhelo sekholamu yangaphambili, ikholomu yokwandisa, i-cylinder ye-extrusion, inkqubo ye-hydraulic phantsi kolawulo lombane, kwaye ixhotyiswe ngesiseko sokubumba, i-thimble, ipleyiti yesikali, ipleyiti yesilayidi njalo njalo.

3. Ukuhlelwa kwendlela ye-aluminium extrusion

Ngokohlobo lwesinyithi kwi-cylinder ye-extrusion: Isikhokelo soxinzelelo kunye nemeko yoxinzelelo, i-extrusion, i-lubricating state, i-extrusion yeqondo lokushisa, i-extrusion speed, okanye iintlobo zesakhiwo esiphezulu, imilo kunye no.engenanto okanye yohlobo lwemveliso, inokohlulwa ibe yi-extrusion elungileyo, i-extrusion engasemva, (kubandakanywa i-extrusion ye-plane strain, i-axisymmetric deformation extrusion, i-extrusion ye-deformation ye-three-dimensional jikelele) i-extrusion esecaleni, i-glass lubricating extrusion, i-Hydrostatic extrusion, i-extrusion eqhubekayo kunye nokunye. kwi.

4. Phambili i-thermal deformation ye-aluminium extrusion

Uninzi lwamashishini emveliso yealuminiyam etshisayo asebenzisa indlela ye-deformation extrusion yangaphambili ngokufa okuthe ngqo (i-flat die, cone die, shunt die) ukufumana iiprofayili ze-aluminium ezingaguqukiyo kunye necandelo kunye nemilo efunwayo.

Inkqubo ye-extrusion yangaphambili ilula, iimfuno zezixhobo aziphezulu, amandla okuguqula isinyithi aphakamileyo, uluhlu lwemveliso lubanzi, ukusebenza kwe-aluminium kuyalawuleka, ukuguquguquka kwemveliso kukhulu, kwaye ukubumba kulula ukuyigcina nokuhlaziya.

Isiphene sinomphezulu wokukhuhla ukusuka kwityhubhu ye-aluminium engaphakathi, ukusetyenziswa kwamandla kuphezulu, isilinda sokukhuhla kulula ukwenza ubushushu, kunye nokwandisa ukungazinzi kweeprofayili, ukunciphisa ukusebenza kakuhle kokugqiba imveliso, ukunciphisa isantya se-aluminium kunye ne-aluminium alloy extrusion, ngokukhawuleza. ukunxiba kunye nobomi benkonzo ye-extrusion kufa, iimveliso ezingalinganiyo.

5. Uhlobo olushushu lwe-aluminium alloy deformation, ukusebenza kunye nokusetyenziswa

Iindidi ze-aluminiyam ye-deformation eshushu zihlulwe zibe ziindidi ezi-8 ngokuhambelana nokusebenza kunye nokusetyenziswa, ukusebenza kwazo kunye nokusetyenziswa kwahlukile:

1) I-aluminium ecocekileyo (i-L series) ehambelana ne-brand yamazwe ngamazwe ye-1000 series aluminiyam ecocekileyo.

I-aluminium ecocekileyo ye-industrial, i-machinability egqwesileyo, ukuxhathisa ukubola, kunye nonyango lomphezulu kunye nokuhanjiswa kombane, kodwa amandla aphantsi, asetyenziswa kwimpahla yasekhaya, iimveliso zombane, amayeza kunye nokupakishwa kokutya, ukuhanjiswa kunye nokuhanjiswa kwezinto, njl.

2) I-Duralumin (Ly) ihambelana ne-brand yamazwe ngamazwe i-2000 Al-Cu (Aluminium-copper) i-alloy.

Isetyenziswe kumacandelo amakhulu, isekela, umxholo we-Cu ophezulu, ukuxhathisa ukubola.

I-3) I-aluminium ye-rust-proof (LF) ehambelana ne-brand yamazwe ngamazwe i-3000 Al-Mn (i-aluminium manganese) i-alloy.

Ukunyangwa kokushisa akuqiniswanga, ukucwangciswa, ukuxhathisa ukubola kunye ne-aluminium ecocekileyo, amandla aphuculwe, ukusebenza kakuhle kwe-welding, esetyenziswa ngokubanzi kwiimfuno zemihla ngemihla, izinto zokwakha, izixhobo kunye neminye imiba.

I-4) I-Aluminiyam ekhethekileyo (LT) ehambelana ne-brand yamazwe ngamazwe i-4000 Al-Si alloy.

Ubukhulu becala izinto ze-welding, indawo ephantsi yokunyibilika (i-575-630 degrees), i-fluidity enhle.

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

Ukunyangwa kobushushu akuqiniswanga, ukuxhathisa kwe-corrosion, i-weldability, i-gloss ye-gloss egqwesileyo, ngokulawulwa komxholo we-Mg, unokufumana amanqanaba ahlukeneyo amandla e-alloy.Inqanaba eliphantsi lezinto zokuhlobisa, izixhobo eziphambili;Inqanaba eliphakathi kwiinqanawa, izithuthi, izixhobo zokwakha;Inqanaba eliphezulu elisetyenziselwa amacandelo e-welding kwizityalo zekhemikhali zeenqanawa kunye nezithuthi.

6) 6000Al-Mg-Si ingxubevange.

I-Mg2Si imvula iqinisa unyango lobushushu inokomeleza i-alloy, ukuxhathisa okulungileyo kokuhlwa, ukomelela okuphakathi, ukusebenza kakuhle kwe-thermal, ngoko isetyenziswa ngokubanzi njengezinto ezikhuphayo, ukubunjwa okulungileyo, ubunzima obuphezulu bunokufunyanwa ngokucinywa.Isetyenziswa ngokubanzi ekwakheni iiprofayili kwaye ngowona mthombo wezinto eziphathekayo kwishishini.

I-7) I-aluminium ye-Superhard (LC) ihambelana ne-brand yamazwe ngamazwe i-7000Al-Zn-Mg-Cu (Al-Zn-Mg-Cu) i-alloy ye-aluminium yamandla aphezulu kunye ne-Al-Zn-Mg i-alloy esetyenziselwa amacandelo e-welding, anamandla amakhulu, ukuwelda okugqwesileyo kunye nokusebenza kokucima, kodwa ukubola koxinzelelo olubi kunye nokumelana nokuqhekeka, ekufuneka kuphuculwe ngonyango olufanelekileyo lobushushu.Eyangaphambili isetyenziswa ikakhulu kwinqwelomoya nakwimpahla yezemidlalo, ngelixa eyokugqibela isetyenziselwa ukuwelda izixhobo zezithuthi zikaloliwe.

8) 8000 (Al-Li) I-aluminium-lithium ingxubevange.

Olona phawu lubalaseleyo kukuba ingxinano yi-8% -9% esezantsi kune-7000-series, ukuqina okuphezulu, amandla aphezulu, ubunzima obukhanyayo, olu luhlu luphantsi kophuhliso (ikhono lokuchasana nokubola kwesinyithi se-aluminium phantsi kweemeko ezinzima azizange zoyiswe ngokupheleleyo. ), ikakhulu esetyenziswa kwiinqwelomoya, imijukujelwa, iinjini kunye nezinye izicelo zomkhosi.
