Umzimba wesithuthi owenziwe ngezinto zeprofayili ye-aluminium yemizi-mveliso unezibonelelo zobunzima bokukhanya, ukuxhathisa umhlwa, inkangeleko entle yokuba tyaba kunye nezinto ezinokuphinda zisetyenziswe, ngoko ke ithandwa ziinkampani zothutho zasezidolophini kunye namasebe othutho lukaloliwe kwihlabathi liphela.
Imizimba yemoto ye-aluminiyam yemizi-mveliso inemisebenzi engenakubuyiselwa ekwenziweni kololiwe ohamba ngesantya esiphezulu, ngoko ke isantya sophuhliso sikhawuleza kakhulu. Okwangoku, iimoto zeprofayili ye-aluminium ye-industrial ene-aluminiyam yonke i-aluminiyam isetyenziswe ngokubanzi ekwenzeni ii-EMU kunye neenqwelo zokuhamba zikaloliwe zasezidolophini, ngakumbi izakhiwo zetsimbi ze-EMU ezihamba ngesantya esiphezulu zonke zitshintshwa yimizimba yemoto yeprofayili ye-aluminium yoshishino.
Kwinkqubo yokwenziwa kwemizimba yemoto ye-aluminium yeprofayili yeshishini, ngenxa yokusetyenziswa kakhulu kweprofayili yokudibanisa kwisakhiwo, kunye namalungu made kwaye aqhelekileyo, alungele ukufezekiswa kokusebenza okuzenzekelayo, ngoko ke ubuchwephesha bokuwelda obukrelekrele busetyenziswa ngokubanzi eli shishini.

Ukuwelda okuzenzekelayo kukwindawo ebaluleke kakhulu ekudibaniseni imizimba yemoto ye-aluminiyam yeshishini. Sele iqatshelwe ngokubanzi ziinkampani zokuwelda ngenxa yeenzuzo zayo zomgangatho ozinzileyo wokuwelda kunye nokusebenza kakuhle kwemveliso. Ngoku njengoko imfuno kwintsimi ye-welding ehlakaniphile yanda kakhulu, kukholelwa ukuba iteknoloji ye-welding iya kuphuhliswa kakhulu kwixesha elizayo.
Iimpawu zesakhiwo somzimba wemoto ye-aluminium yeprofayili ye-industrial ye-EMUs enesantya esiphezulu
Umzimba wemoto ye-aluminium ye-industrial ye-high-speed EMUs yahlulwe ngokukodwa kwi-industrial body yeprofayili ye-aluminium ye-industrial kunye nomzimba wemoto yentloko yeprofayili ye-aluminium yoshishino. Umzimba wesithuthi esiphakathi weprofayili ye-aluminium ye-industrial yenziwe ikakhulu ngamacandelo amane: i-underframe, udonga olusecaleni, uphahla, kunye nodonga lokugqibela. Umzimba wemoto yentloko yeprofayili ye-aluminium ye-industrial iqulunqwe ikakhulu ngamacandelo amahlanu: i-underframe, udonga olusecaleni, uphahla, udonga lokugqibela kunye nangaphambili.
Ukusetyenziswa kwetekhnoloji ye-welding ye-MIG ezenzekelayo ekwenzeni imizimba yemoto ye-aluminium yeprofayile ye-EMUs enesantya esiphezulu.
I-welding yeprofayili ye-aluminium ye-industrial body body in high-speed EMUs idla ngokuhlulwa ibe yi-welding ngokuzenzekelayo yeendawo ezinkulu, iinxalenye ezincinci kunye nendibano jikelele. Ukuwelda okuzenzekelayo kweendawo ezinkulu ngokuqhelekileyo kubhekisa kwi-welding ezenzekelayo yeepaneli zophahla, iipaneli zophahla olusicaba, imigangatho, uphahla kunye neendonga ezisecaleni; Ukuwelda okuzenzekelayo kwamalungu amancinci ngokubanzi kubhekisa kwi-welding ezenzekelayo yeendonga zokuphela, imida, iindonga zokwahlula, iipleyiti zesiketi kunye nezihlalo ze-coupler. I-welding ngokuzenzekelayo yendibano jikelele ngokubanzi ibhekisela kwi-welding ngokuzenzekelayo yamalungu phakathi kodonga olusecaleni kunye nophahla, kunye nodonga olusecaleni kunye ne-underframe. Utyalo-mali kwizixhobo ezinkulu ze-welding ezingundoqo yimeko eyimfuneko yokuvelisa imizimba yemoto ye-aluminium yeprofayile.
Kwinqanaba lokuqala lokuveliswa kweeprofayili ze-aluminium ze-EMU ze-high-speed, i-robot ye-IGM ye-welding ye-wire enye yayisetyenziselwa i-welding ngokuzenzekelayo. Ngokwandiswa komthamo wemveliso ye-EMU kunye nohlengahlengiso lwenkqubo yoyilo, i-robot ye-IGM ye-welding ye-wire enye iye yashiywa ngenxa yokusebenza kwayo okuphantsi kwemveliso. Ukuza kuthi ga ngoku, zonke iinxalenye ezinkulu zemizi-mveliso ye-aluminium yeprofayili yemoto ye-EMU enesantya esiphezulu idityaniswe yi-robot ye-IGM ye-welding ye-wire.
Usetyenziso olubanzi lwetekhnoloji ye-welding ye-MIG ezenzekelayo ekwenzeni i-EMU yemizi-mveliso ye-aluminium yeprofayili yemizila yemoto iye yaphucula kakhulu inqanaba letekhnoloji ye-welding kunye nomthamo wokuvelisa umgca wemveliso, ngaloo ndlela iqinisekisa umgangatho wemveliso yemizimba yemoto ye-aluminium yeprofayili yeshishini. I-EMU enesantya esiphezulu, yenze igalelo elibalaseleyo kwinkalo yokwenziwa koololiwe ngesantya esiphezulu.

Ukusetyenziswa kweTekhnoloji ye-Friction Stir Welding kukwenziwa koShishino lweAluminiyam yeProfayili yesithuthi Umzimba wee-EMU ezikhawulezayo
I-Friction Stir Welding (Umthombo: grenzebach)
Ifriction stir welding (FSW) bubuchule bokudibanisa isigaba esiqinileyo. Umdibaniso odibeneyo uneempawu ezibalaseleyo zomatshini kunye ne-welding deformation encinci. Akudingi ukongeza igesi yokukhusela kunye nocingo lwe-welding, kwaye akukho ukunyibilika, uthuli, isitshizi kunye nokukhanya kwe-arc ngexesha lenkqubo ye-welding, eyona iteknoloji entsha yokudibanisa indalo. Kwiminyaka nje embalwa emva kokufika kwetekhnoloji yeFSW, kuye kwenziwa inkqubela phambili enkulu kwindlela yayo yokuwelda, izinto ezisebenzayo, izixhobo zokuwelda kunye nezicelo zobunjineli.
