1. Intshayelelo
Ngokukhula ngokukhawuleza kweshishini le-aluminium kunye nokunyuka okuqhubekayo kweetoni zoomatshini be-aluminium extrusion, iteknoloji ye-porous mold aluminium extrusion iye yavela. I-Aluminiyamu yokukhupha i-porous mold iphucula kakhulu ukusebenza kakuhle kwemveliso ye-extrusion kwaye ibeka iimfuno eziphezulu zobuchwepheshe kuyilo lokungunda kunye neenkqubo zokukhupha.
2 Inkqubo ye-Extrusion
Impembelelo yenkqubo ye-extrusion ekusebenzeni kwemveliso ye-porous mold aluminium extrusion ibonakala ikakhulu kulawulo lwemiba emithathu: ukushisa okungenanto, ubushushu bokubumba, kunye nobushushu bokuphuma.
2.1 Iqondo lobushushu elingenanto
Ubushushu obufanayo obungenanto bunempembelelo ebalulekileyo kwimveliso ye-extrusion. Kwimveliso yokwenyani, oomatshini bokukhupha abaqhelene nokuguquguquka komphezulu badla ngokufudunyezwa kusetyenziswa amaziko amaninzi angenanto. Iziko ezininzi ezingenanto zibonelela ngokufudumeza okufanayo kunye nokucokisekileyo okungenanto kunye neempawu ezilungileyo zokugquma. Ukongezelela, ukuze kuqinisekiswe ukusebenza kakuhle, indlela "yokushisa ephantsi kunye nesantya esiphezulu" isoloko isetyenziswa. Kule meko, ukushisa okungenanto kunye nokushisa okuphumayo kufuneka kuhambelane ngokusondeleyo nesantya sokukhupha, kunye nezicwangciso ezithathela ingqalelo utshintsho kwixinzelelo lwe-extrusion kunye nemeko yendawo engenanto. Iisetingi zobushushu ezingenanto zixhomekeke kwiimeko zokwenyani zemveliso, kodwa njengesikhokelo ngokubanzi, kwi-porous mold extrusion, amaqondo obushushu angenanto agcinwa phakathi kwe-420-450 ° C, kunye ne-flat dies ibekwe phezulu kancinci nge-10-20 ° C xa kuthelekiswa nokwahlukana kuyafa.
2.2 Ubushushu boMngundo
Ngokusekwe kumava emveliso kwisiza, ubushushu bomngundo kufuneka bugcinwe phakathi kwe420-450°C. Amaxesha okufudumeza okugqithisileyo kunokukhokelela kukhukuliseko lokungunda ngexesha lokusebenza. Ngaphezu koko, ukubekwa kokungunda okufanelekileyo ngexesha lokufudumeza kubalulekile. Iimbumba akufanele zihlanganiswe ngokusondeleyo kakhulu, zishiye indawo phakathi kwazo. Ukuthintela ukuphuma komoya kwesithando somlilo okanye ukubekwa okungafanelekanga kunokukhokelela ekufudumeni okungalinganiyo kunye nokugqithiswa okungahambelaniyo.
Izinto ezi-3 zokungunda
Uyilo lokungunda, ukusetyenzwa komngundo, kunye nokugcinwa kokungunda kubalulekile ekubunjweni kwe-extrusion kwaye kuchaphazela ngokuthe ngqo umgangatho womphezulu wemveliso, ukuchaneka komda, kunye nokusebenza kakuhle kwemveliso. Ukutsalwa kwiinkqubo zemveliso kunye namava oyilo lokungunda, makhe sihlalutye le miba.
3.1 Uyilo lokungunda
Umngundo sisiseko sokwenziwa kwemveliso kwaye udlala indima ebalulekileyo ekumiseleni imilo, ukuchaneka komda, umgangatho womphezulu, kunye neempawu zezinto zemveliso. Kwiiprofayili zokubumba ezinabileyo ezineemfuno eziphezulu zomphezulu, ukuphuculwa komgangatho womphezulu kunokufezekiswa ngokunciphisa inani lomngxuma wokuguqula kunye nokuphucula ukubekwa kweebhulorho zokuguqula ukuphepha owona mphezulu wokuhombisa weprofayile. Ukongeza, ukufa kweflethi, ukusebenzisa uyilo lomngxuma ojikelezayo kunokuqinisekisa ukuhamba kwentsimbi efanayo kwimingxunya yokufa.
3.2 Ukulungiswa kokungunda
Ngexesha lokulungiswa kokungunda, ukunciphisa ukuxhathisa ukuhamba kwesinyithi kwiibhulorho kubalulekile. Ukugaya iibhulorho zokuguqula ngokutyibilikayo kuqinisekisa ukuchaneka kwezikhundla zebhulorho yokuphazamiseka kwaye kunceda ukufezekisa ukuhamba kwentsimbi efanayo. Kwiiprofayili ezineemfuno eziphezulu zomgangatho ophezulu, ezifana neepaneli zelanga, cinga ukwandisa ukuphakama kwegumbi le-welding okanye ukusebenzisa inkqubo ye-welding yesibini ukuqinisekisa iziphumo ezilungileyo ze-welding.
3.3 Ukugcinwa koMngundo
Ukugcinwa rhoqo komngundo kubalulekile ngokulinganayo. Ukupholisa iimbumba kunye nokuphumeza ukugcinwa kwe-nitrogenization kunokuthintela imiba efana nobunzima obungalinganiyo kwiindawo zokusebenza zokubumba.
4 Umgangatho ongenanto
Umgangatho wesithuba esingenanto kunempembelelo ebalulekileyo kumgangatho wemveliso, ukusebenza kakuhle kwe-extrusion, kunye nomonakalo wokungunda. Izithuba ezikumgangatho ophantsi zingakhokelela kwiingxaki zomgangatho onje ngeegrooves, ukujika kombala emva kwe-oxidation, kunye nokunciphisa ubomi bokungunda. Umgangatho ongenanto ubandakanya ukubunjwa okufanelekileyo kunye nokufana kwezinto, zombini ezichaphazela ngokuthe ngqo ukuphuma kwe-extrusion kunye nomgangatho womphezulu.
4.1 Ulungelelwaniso loBumemo
Ukuthatha iiprofayili zephaneli yelanga njengomzekelo, ulungelelwaniso olufanelekileyo lwe-Si, Mg, kunye ne-Fe kwi-alloy ekhethekileyo ye-6063 ye-porous mold extrusion ibalulekile ekufezekiseni umgangatho ofanelekileyo womphezulu ngaphandle kokuphazamisa iimpawu zoomatshini. Isixa esipheleleyo kunye nomlinganiselo we-Si kunye ne-Mg zibalulekile, kwaye ngokusekelwe kumava okuvelisa ixesha elide, ukugcina i-Si + Mg kuluhlu lwe-0.82-0.90% lufanelekile ukufumana umgangatho ofunekayo wendawo.
Kuhlalutyo lwezibhengezo ezingahambelaniyo kwiipaneli zelanga, kwafunyaniswa ukuba ukulandelela izinto kunye nokungcola kwakungazinzanga okanye kudlule imida, kuchaphazela kakhulu umgangatho womhlaba. Ukongezwa kwezinto ngexesha lokudibanisa kwi-melting shop kufuneka kwenziwe ngokucophelela ukuphepha ukungazinzi okanye ukugqithisa kwezinto zokulandelela. Kuhlelo lwenkunkuma yoshishino, inkunkuma yokukhupha ibandakanya inkunkuma yokuqala efana nokusikwa kunye nemathiriyeli esisiseko, inkunkuma yesibini ibandakanya inkunkuma yasemva kokulungiswa ukusuka kwimisebenzi efana ne-oxidation kunye nomgubo wokugquma, kunye neeprofayili zokugquma i-thermal zihlelwa njengenkunkuma ephezulu. Iiprofayili ze-Oxidized kufuneka zisebenzise i-blank ekhethekileyo, kwaye ngokubanzi akukho nkunkuma iya kongezwa xa izinto zanele.
4.2 Inkqubo yeMveliso engenanto
Ukufumana izikhewu ezikumgangatho ophezulu, ukuthotyelwa ngokungqongqo kwiimfuno zenkqubo yokuhlanjululwa kwenitrogen kunye nexesha lokumisa i-aluminium kubalulekile. Izinto ze-alloying zongezwa ngokuqhelekileyo kwifom yebhloko, kwaye ukuxuba ngokucokisekileyo kusetyenziselwa ukukhawuleza ukuchithwa kwabo. Ukuxuba okufanelekileyo kuthintela ukubunjwa kweendawo ezihlala kwindawo ephezulu yoxinaniso lwezinto ze-alloy.
Ukuqukumbela
I-alloys ye-aluminiyam isetyenziswa ngokubanzi kwizithuthi zamandla amatsha, kunye nokusetyenziswa kumacandelo esakhiwo kunye namalungu afana nomzimba, injini kunye namavili. Ukusetyenziswa okwandisiweyo kwee-alloys ze-aluminium kwishishini leemoto kuqhutywa yimfuno yokusebenza kakuhle kwamandla kunye nokugcinwa kokusingqongileyo, kudityaniswa nokuqhubela phambili kwitekhnoloji ye-aluminium alloy. Kwiiprofayili ezineemfuno zomgangatho ophezulu womphezulu, ezifana neetreyi ze-aluminiyam zebhetri ezinemingxuma emininzi yangaphakathi kunye neemfuno eziphezulu zokusebenza koomatshini, ukuphucula ukusebenza kakuhle kwe-porous mold extrusion kubalulekile kwiinkampani ukuba ziphumelele kumxholo wenguqu yamandla.
