Umgaqo weAluminiyam Extrusion
I-Extrusion yinkqubo yokwenza ngokuchasene nenkqubo yokususa izinto.Izinto ezifudumalayo, ezifana ne-aluminium, zinyanzeliswa ngokuvula ukwenza iprofayili emile.Kwi-aluminiyam extrusion, i-aluminiyam ekrwada ifudunyezwa kuqala ize ibunjwe ibe kwindawo enqwenelekayo ngokuyityhala ngedayi usebenzisa iplunger.Ngokomzekelo, inkqubo ye-aluminium extrusion ifana nokucofa i-toothpaste;amandla asetyenziswayo anokufaniswa namandla asetyenziswayo xa ucinezela ityhubhu yentlama ngomnwe wakho, kwaye xa ucinezela, intlama yamazinyo ibonakala ngendlela yokuvula ityhubhu.
Ngokuqinisekileyo, imeko yokwenyani inzima kakhulu kunoko, xa ufuna ukusebenzisa inkqubo ye-aluminium extrusion kukulungele ukunxibelelana nenjineli enamava, iinjineli zethu zineminyaka engamashumi eminyaka yamava kwishishini le-aluminium extrusion kwaye banokuphendula imibuzo yakho ngokukhawuleza, kwaye sinikela ainkonzo yokucaphula yasimahla,ungajonga wethuiphepha lenkonzo ye-aluminium extrusion.Ukubuyela kwinqanaba, eli nqaku liza kukuchazela ezinye iinyani ezisisiseko malunga ne-aluminium extrusion: inkqubo ye-extrusion;iimilo ezinokukhutshelwa;izinto eziluncedo kunye nezingeloncedo, kunye neengcebiso zokusebenzisa i-aluminium extrusion.
Ilog yeAluminiyam
Iintlobo ze-Aluminiyam Extrusion Molding
Kukho iintlobo ezimbini zeenkqubo ze-extrusion,ngqo kunye nokungathanga ngqo.Nge-extrusion ngqo intloko yokufa ihlala imile kwaye i-punch ehambayo inyanzelisa isinyithi kuyo.Ngokwahlukileyo, kwi-extrusion engathanga ngqo i-billet ihlala imile ngelixa i-die ekupheleni kwe-plunger ihamba ngokuchasene ne-billet, idala uxinzelelo olufunekayo ukuze isinyithi sihambe ngokufa.
I-Extrusion ngqo
I-extrusion ngqo,eyaziwa ngokuba phambili extrusion, yeyona nkqubo ixhaphakileyo extrusion.Isebenza ngokubeka i-billet kwisitya esinodonga olungqingqwa.Ibillet ityhalwa kwidayizi ngeplunger okanye isikrufu.Eyona nto ingathandekiyo yale nkqubo kukuba amandla afunekayo ukukhupha i-billet inkulu kunokuba ifunwa yinkqubo ye-extrusion engathanga ngqo.ngenxa yamandla angeniswe yi-friction ngenxa yesidingo sokuba i-billet idlule kubo bonke ubude bomkhumbi.Ngoko ke, amandla aphezulu afunekayo asekuqaleni kwenkqubo kwaye ayancipha njengoko i-billet isetyenziswe phezulu.
I-Extrusion engathanga ngqo
Ini-extrusion engathanga ngqo(ekwaziwa njenge-reverse extrusion), ibhilethi isala imile ngelixa i-fae ekupheleni kweplunger isiya kwibhilethi, ngaloo ndlela isusa amandla okukhuhlana.Oku kuphumela koku kulandelayoiingenelo.
1.I-25% ukuya kwi-30% i-friction engaphantsi, evumela ukuba iindawo ezingenanto ezinkulu zikhutshwe, isantya esiphezulu, kunye nokwandisa amandla okugqithisa amacandelo amancinci amancinci.
2. Amathuba amancinci okuba aphuke ngenxa yokungabikho kobushushu obuveliswa kukukhuhlana.
3. Ubomi belinen yomkhumbi ixesha elide ngenxa yokuguga kancinci
4. Ukusetyenziswa okufanayo kweebhilithi, ngoko ke iziphene ze-extrusion kunye nemimandla ye-peripheral ecoarse-grained ayinakwenzeka ukuba yenzeke.
Izinto ezingeloncedo
1. Ukungcola kunye neziphene kumphezulu we-billet kunokuchaphazela umgangatho we-extrusion.Ukucombulula le ngxaki, iibhilithi zinokucocwa ngocingo, zenziwe ngoomatshini, okanye zicocwe ngamachiza phambi kokusetyenziswa
2. Akunjalo njengento eguquguqukayo njenge-extrusion ngokuthe ngqo kuba indawo enqamlezileyo inqunyelwe ngobungakanani obukhulu besiqu.
Imiba echaphazela iMeko yokuKhulisa
Ubume yinto emisela inxalenye yeendleko kunye nokukhululeka kwe-extrusion.Ngethuba lenkqubo ye-extrusion, iintlobo ezahlukeneyo zeemilo zinokukhutshwa.Ngokubanzi, iimilo ezikhutshiweyo zinokwahlulwa zibe ziindidi ezintathu.
1. Iqinile, ingabi nazingcango zivaliweyo okanye zivuleke (oko kukuthi, iintonga, imiqadi, okanye iikona)
2. Umgongxo, onesikhala esinye okanye ngaphezulu (oko kukuthi, iityhubhu zesikwere okanye ezixande)
3. Umngxuma ophakathi, ovaleke ngokuyinxenye (oko kukuthi, “C” ityhubhu enezikhewu ezimxinwa)
Kwimveliso yokwenyani, kukho inani lemiqobo ekufuneka iqwalaselwe.Ezi ziquka:
1. Ubungakanani
2. Ubume
3. Ingxubevange – Ukwakheka kweekhemikhali zezinye izinto ezidityaniswe kwi-aluminiyam esulungekileyo ukuphucula iimpawu zayo (umzekelo, amandla, njl.njl.)
4. I-Extrusion Ratio - Indawo yebillet / indawo yokuma
5. Ubungakanani bolwimi – Ububanzi nobunzulu besithuba
6. Ukunyamezela - Umda wokuhluka apho inxalenye okanye imveliso inokuveliswa kuyo
7. Gqiba
8. I-Coefficient - Shape circumference / weight per meter
Inqununu yeAluminiyam Extrusion
Iinketho zeAluminiyam eyongezelelweyo
| 1100 | Ithambile, ayinyangeki bubushushu kodwa inokukhutshelwa kwiimilo ezintsonkothileyo ezinomphezulu omenyezelayo.Le alloy ingasetyenziselwa ukubonakala kwezinto kunye neetyhubhu zokutshintsha ubushushu. |
| 3003——3000 | le ngxubevange idla ngokukhutshelwa iityhubhu zokutshintsha ubushushu kuphela. |
| 6063 | Efanelekileyo kwiinjongo zokuhlobisa, inomphezulu ogqityiweyo kwaye inokukhutshwa kunye neempawu ezinzima ezifana neendonga ezincinci okanye iinkcukacha ezintle.Iyakwazi ukumelana nomhlwa, kodwa inamandla asezantsi e-weld, nangona i-welded ngokulula. |
| 6061 | Le ngxubevange yomelele kune-6063 kwaye iyeyona nto iphambili yolwakhiwo lwezothutho kunye necandelo lomatshini.I-alloy kulula ukuyikhupha kwaye idibanise.Ezi zakhiwo ezidityaniswe nokuqina okuphezulu kokuqhekeka kunye namandla okudinwa okuhle zenza isihlangu kumalungu adityanisiweyo akhiweyo, kubandakanywa iifreyimu zemoto, iilori kunye neetrailer, iimoto zikaloliwe kunye nemibhobho. |
| 7004 | Olunye uluhlu lwe "low end" 7000 series (Al-Zn) alloys ukuba press ubushushu enyangekayo, ngokufanelekileyo extrudable kwaye zibiza kancinci ngaphezu 6061. Uthotho 7000 ngokwembali isetyenziswa ngokubanzi kwimpahla yezemidlalo, ibhayisekile kunye namashishini izithuthuthu.Iialloyi ezingama-7004 zinesivuno esigqibeleleyo kunye namandla okuqina ngaphezulu kwe-40,000 kunye ne-50,000 psi, ngokulandelanayo. |
Inzuzo yeAluminiyam Extrusion
1. Umgangatho ophezulu wemveliso jikelele.Ukubunjwa kwe-Extrusion kunokuphucula isakhiwo kunye neempawu zomatshini ze-aluminium.Emva kokucima, i-longitudinal (i-extrusion direction) iipropathi zemishini yeemveliso ezikhutshiweyo ziphezulu kakhulu kunezo zemveliso ezifanayo eziveliswa ngezinye iindlela zokucubungula.Xa kuthelekiswa nokuqengqeleka, ukwenza kunye nezinye iindlela zokusetyenzwa, iimveliso ezikhutshiweyo zinokuchaneka okuphezulu komgangatho kunye nomgangatho olungileyo womphezulu.
2. Uluhlu olubanzi lweemveliso.Iiprofayili ezongeziweyo azikwazi ukuvelisa kuphela imibhobho elula, imivalo kunye neengcingo, kodwa kunye neemilo ezinqamlekileyo ezinqamlezileyo, iimveliso zeprofayili eziqinileyo kunye nezingenanto.Iimveliso ezongeziweyo zikwafumaneka kuluhlu olubanzi lobukhulu, ukusuka kwiityhubhu ezinkulu kakhulu kunye neeprofayili ezinobubanzi obuyi-500-1000 mm ukuya kwiiprofayili ezichanekileyo ezinobungakanani bemicinga yematshisi.
3. Ukuguquguquka okuphezulu kwemveliso.Ukubunjwa kwe-Extrusion kunika ukuguquguquka okukhulu.Iimveliso zeemilo ezahlukeneyo, ubungakanani, iinkcukacha kunye neendidi ezahlukeneyo zinokuveliswa kumatshini omnye ngokutshintsha nje ukufa.Ukongeza, umsebenzi wokutshintsha i-die ulula, ulungile, ugcina ixesha kwaye uyasebenza.
4. Inkqubo ilula kwaye utyalo-mali kwizixhobo luphantsi.Xa kuthelekiswa nombhobho kunye neenkqubo zokuvelisa iprofayili ezifana ne-perforation rolling kunye ne-groove rolling, ukubunjwa kwe-extrusion kunenzuzo yokuhamba kwexesha elifutshane, inani elincinci lezixhobo kunye notyalo-mali oluphantsi.
Unyino lweAluminiyam Extrusion
1. Iimpawu zeethishu zemveliso ezingalinganiyo.Umphezulu ongalinganiyo, iziko, intloko kunye nomsila weemveliso ezikhutshiweyo ngenxa yokungalingani kokuhamba kwesinyithi ngexesha lokukhupha.
2. Iimeko zokusebenza ze-extrusion die zibuhlungu kwaye ziyakwazi ukugqoka.Ngethuba lenkqubo ye-extrusion, i-billet ikwimeko esondeleyo evaliweyo kunye noxinzelelo lwe-tee ephezulu.Ngelo xesha, ukufa ngokuqhelekileyo kuxhomekeke kwiqondo lokushisa eliphezulu kunye nokungqubuzana okukhulu ngexesha lenkqubo eshushu ye-extrusion, echaphazela kakhulu amandla kunye nobomi benkonzo yokufa.
3. Ukusebenza kwemveliso ephantsi.Ngaphandle kwendlela ye-extrusion eqhubekayo ephuhliswe kwiminyaka yamuva nje, indlela ye-extrusion eqhelekileyo ayikwazi ukufikelela kwimveliso eqhubekayo.Isantya esiphezulu se-extrusion siphantsi kakhulu kunesantya sokuhamba, kwaye ilahleko ye-jometri ye-scrap kunye nemveliso yemveliso ye-extrusion iphantsi.
I-Prolean inika uluhlu olubanzi lwezixhobo ze-aluminium extrusion, kuquka isinyithi kunye neeplastiki.Nceda ubone iisampula uluhlu lwemathiriyelisisebenzisa.Ukuba ufuna imathiriyeli engadweliswanga apha, nceda uqhagamshelane nathi njengoko siya kuba nakho ukukukhuphela yona.
