1 Ukusetshenziswa kwe-aluminium alloy embonini yezimoto
Njengamanje, ngaphezu kwe-12% kuya ku-15% yokusetshenziswa kwe-aluminium emhlabeni kusetshenziswa ngumkhakha wezimoto, namanye amazwe athuthukile adlula ama-25%. Ngo-2002, yonke imboni yezemoto yaseYurophu idla amathani ama-metric ayizigidi eziyi-1.5 ngonyaka. Cishe amathani ama-metric acishe abe ngu-250,000 asetshenziselwa ukwenza umzimba, amathani ama-metric angama-800,000 okukhiqiza uhlelo lokuhambisa izimoto, kanye namathani we-metric angeziwe wokukhiqiza imoto kanye nezinhlelo zokukhiqiza. Kuyabonakala ukuthi imboni yezokukhiqiza izimoto isiphenduke umthengi omkhulu wezinto zokwakha ze-aluminium.
Izidingo ezi-2 zobuchwepheshe zamashidi e-aluminium esitembu ekuteleni izitembu
2.1 Ukwakha nezidingo zokufa kwamashidi e-aluminium
Inqubo eyakha i-Aluminium Alloy ifana neyamashidi ajwayelekile abanda okubandayo, okungenzeka ukuthi anciphise imfucumfucu kanye ne-aluminium scrap ngesizukulwane ngokungeza izinqubo. Kodwa-ke, kunomehluko ezifundweni zokufa ngokuqhathaniswa namashidi agoqelwe abandayo.
2.2 Isitoreji eside se-aluminium
Ngemuva kokuqina kokuqina, amandla okuvutha ama-aluminium akhuphuka, anciphise ukucubungula kwabo onqenqemeni. Lapho wenza ufe, cabanga ukusebenzisa izinto ezihlangabezana nezidingo ezingenhla nokuqinisekisa ukuqinisekiswa ngaphambi kokukhiqizwa.
Amafutha we-oyela / ukugqekeza uwoyela osetshenziselwa ukukhiqizwa athambekele ekuguqukeni. Ngemuva kokuvula ukupakishwa kweshidi, kufanele kusetshenziswe ngokushesha noma kuhlanziwe futhi kufakwe u-oli ngaphambi kokunyathela.
Ingaphezulu lithambekele kwi-oxidation futhi akufanele ligcinwe obala. Ukuphathwa okukhethekile (ukufakwa) kuyadingeka.
Izidingo ezi-3 zobuchwepheshe ze-aluminium stang amashidi e-welding
Izinqubo eziphambili ze-Welding ngesikhathi senhlangano ye-Aluminium Alloy Bodies zifaka ukumelana nokuphikiswa, ukuguquguquka okubandayo okubandayo, i-tungsten inert gas (tig) i-welding, i-riveting, ukubhoboza nokugaya / ukugaya.
3.1 Ukushiswa kwe-welding ngaphandle kokuvuselelwa kwamashidi e-aluminium
Izakhi ze-Aluminium Sheet ngaphandle kwama-riveting zakhiwa ngokukhishwa okubandayo kwezingqimba ezimbili noma ngaphezulu zamashidi wensimbi asebenzisa imishini yengcindezi kanye nokubumba okukhethekile. Le nqubo idala amaphuzu okuxhuma ashumekiwe anamandla athile ashubile futhi agunda. Ubukhulu bokuxhuma amashidi bungafana noma buhlukile, futhi bangaba nezingqimba ezinamathela noma ezinye izingqimba eziphakathi, ngezinto zokwakha ezifanayo noma ezihlukile. Le ndlela ikhiqiza ukuxhumana okuhle ngaphandle kwesidingo sezixhumi ezisizayo.
3.2 Ukumelana nokushibilika
Njengamanje, i-Aluminium Alloy Ukumelana nokuphikiswa kokuphikiswa ngokuvamile kusetshenziswa imvamisa ephakathi nendawo noma izinqubo zokumelana nokuvama okuthe xaxa. Le nqubo ye-welding incibilikisa insimbi eyisisekelo ngaphakathi kobubanzi be-walding ye-welding ngesikhathi esifushane kakhulu ukwakha ichibi le-weld,
Amabala we-Welding asheshe aphole ngokushesha ukwakha ukuxhumana, ngamathuba amancane okukhiqiza uthuli lwe-aluminium-magnesium. Iningi le-welding fumes elikhiqizwa liqukethe izinhlayiya ze-oxide ezivela ebusweni bensimbi kanye nokungcola komhlaba. Ukungena komoya omncane wendawo kuhlinzekwa ngesikhathi senqubo ye-welding ukususa ngokushesha lezi zinhlayiya emkhathini, futhi kukhona ukufakwa okuncane kothuli lwe-aluminium-magnesium.
3.3 cmt okubandayo ukuguqulwa kwe-welding kanye ne-tig welding
Lezi zinqubo ezimbili ze-welding, ngenxa yokuvikelwa kwegesi ye-inert, khiqiza izinhlayiya zensimbi ezincane ze-aluminium-magnesium emazingeni okushisa aphezulu. Lezi zinhlayiya zingagadla endaweni yokusebenza ngaphansi kwesenzo se-arc, zibeka engcupheni yokuqhuma kothuli lwe-aluminium-magnesium. Ngakho-ke, izinyathelo zokuqapha kanye nezinyathelo zokuvimbela ukwenziwa kothuli nokwelashwa kuyadingeka.
4 Izidingo zobuchwepheshe zamashidi e-aluminium stang enqenqemeni
Umehluko phakathi kwe-aluminium alloy onqenqemeni lokugibela kanye nokugoqa okujwayelekile okubandayo okubandayo kubalulekile. I-Aluminium ayinankinga yensimbi, ngakho-ke ingcindezi eyeqile kufanele igwenywe ngesikhathi sokugoqa, futhi ijubane lokugoqa kufanele libe lihamba kancane, ngokujwayelekile 200-250 mm / s. I-angle ngayinye egoqayo akufanele idlule ku-30 °, futhi ukugoqa okwenziwe yi-V kufanele kugwenywe.
Izidingo zokushisa ze-aluminium alloy rolling: kufanele yenziwe kumazinga okushisa angama-20 ° C. Izingxenye ezithathwe ngokuqondile kusuka kwisitoreji esibandayo akufanele zifakwe ngaphansi kokugoqa ngokushesha.
Amafomu ama-5 nezimpawu zokugibela okunqenqemeni kwamashidi e-aluminium stamp
5.1 Izinhlobo zokugibela onqenqemeni kwamashidi e-aluminium stang
Ukugoqa okujwayelekile kuqukethe izinyathelo ezintathu: okokuqala ukugingqa, okuvela kusesibili, nokugoqa kokugcina. Lokhu kuvame ukusetshenziswa lapho kungekho zidingo zamandla athile kanye nama-anger we-flange angelo angaphandle ajwayelekile.
Ukugingqa isitayela sase-Europe kuqukethe izinyathelo ezine: okokuqala ukugingqa, okuqala ukugoqa, ukugoqa kokugcina, kanye nokugoqwa kwesitayela saseYurophu. Lokhu kuvame ukusetshenziselwa ukugoqa onqenqemeni olude, njengezembozo zangemuva nangemuva. Ukugingqa isitayela sase-Europe kungasetshenziswa futhi ukunciphisa noma ukuqeda iziphambeko zomhlaba.
5.2 Izici zokugibela okunqenqemeni kwamashidi e-aluminium stang
Ngemishini yokugibela ye-aluminium, isikhunta esingezansi kanye ne-Insert block kufanele ifakwe futhi igcinwe njalo nge-800-1200 # sandpaper ukuqinisekisa ukuthi azikho izikhala ze-aluminium ezikhona ngaphezulu.
6 Izimbangela ezahlukahlukene zezinkinga ezibangelwa ukugoqa onqenqemeni kwamashidi e-aluminium stang
Izimbangela ezahlukahlukene zokuphazamiseka okubangelwa ukugingqa onqenqemeni kwezingxenye ze-aluminium kukhonjisiwe etafuleni.
Izidingo eziyi-7 zobuchwepheshe zokuhlanganisa ama-aluminium stang amashidi
7.1 IZIMISO NEMINYANGO NEMISEBENZI YOKUGCINA KWAMAHHALA YOKUGCINA KWAMAHHALA
Ukuphumelela kwamanzi okugeza kubhekisele ekususeni ifilimu ye-oxide eyenziwe ngokwemvelo kanye namabala kawoyela ebusweni bezingxenye ze-aluminium, kanye nokusabela kwamakhemikhali phakathi kwe-aluminium alloy kanye ne-acimic solution, ukudala ifilimu eliminyene le-oxide endaweni yokusebenza. Ifilimu le-oxide, amabala e-oyela, ukubhonga okufakwayo, nokunamathela ebusweni bezingxenye ze-aluminium ngemuva kokunyathela konke kube nomthelela. Ukuthuthukisa ukunamathela kwezikhangiso kanye nama-welds, inqubo yamakhemikhali isetshenziselwa ukugcina ukuxhumeka okunamasheya okuhlala isikhathi eside nokuqina kokuqina ebusweni, kufinyelelwe ukufudumala okungcono. Ngakho-ke, izingxenye ezidinga ukufudumala kwe-laser, ukuguqulwa kwensimbi ezibandayo (CMT), nezinye izinqubo zokufaka izinsimbi zidinga ukuphumelela.
7.2 Inqubo yokugeleza kokuphela kwamanzi okugeza kwamashidi we-aluminium stang
Imishini yokuhamba kwamanzi iqukethe indawo ehlekisayo, indawo yokuhlanza amanzi embonini, indawo yokuhamba, indawo yokuhlanza amanzi ehlanzekile, indawo yokomisa, nohlelo lokuphelelwa ngamandla. Izingxenye ze-aluminium okufanele ziphathwe zibekwe kubhasikidi lokuwasha, elilungisiwe, futhi kwehliswe ethangini. Emathangini aqukethe izixazululo ezahlukahlukene, izingxenye zihlanjululwa kaninginingi nazo zonke izixazululo ezisebenzayo ethangini. Wonke amathangi afakwe amaphampu okujikeleza kanye nama-nozzles ukuqinisekisa ukugcwala okufanayo kwazo zonke izingxenye. Ukugeleza kwenqubo yokugezela kwamanzi kungokulandelayo: Ukuhlehlisa 1 I-Aluminium Castings ingeqa amanzi okugeza amanzi.
7.3 Inqubo yokomisa yokuhamba kwamanzi kwamashidi e-aluminium stang
Kuthatha cishe imizuzu engu-7 yokushisa kwengxenye ukusuka ekushiseni kwegumbi kuya ku-140 ° C, kanye nesikhathi esincane sokuphumula sokunamathela imizuzu engama-20.
Izingxenye ze-aluminium zikhuliswe emazingeni okushisa egumbi liye ekushiseni okubambile ngemizuzu eyi-10, futhi isikhathi sokubamba i-aluminium cishe imizuzu engama-20. Ngemuva kokubamba, kupholile kusuka ekushiseni okuziphethe kuya ku-100 ° C imizuzu engu-7. Ngemuva kokubamba, kupholile ekushiseni kwegumbi. Ngakho-ke, yonke inqubo yokomisa yezingxenye ze-aluminium yimizuzu engama-37.
Isiphetho
Izimoto zanamuhla ziyathuthuka zibheke kokungasindi, ngejubane eliphezulu, ziphephile, zinethezekile, zibiza kakhulu, zisebenza kahle, nezinkomba ezisebenza kahle. Ukuthuthukiswa komkhakha wezimoto kuhlangene kakhulu nokusebenza kahle kwamandla, ukuvikelwa kwemvelo, nokuphepha. Ngokuqwashisa ngokwanda kokuvikelwa kwemvelo, izinto ze-Aluminium Sheet zinezinzuzo ezingenakuqhathaniswa ngezindleko, ubuchwepheshe bokukhiqiza, ukusebenza kwemishini kanye nentuthuko esimeme uma kuqhathaniswa nezinye izinto ezingasindi. Ngakho-ke, i-aluminium alloy izoba yizinto ezithandwayo ezilula embonini yezimoto.
