Ukusetyenziswa kwe-MFDC Spot Welding Machines kwi-Automotive Door Manufacturing

Iingcango zeemoto, ngakumbi iiphaneli zangaphandle, zihlelwa njengemigangatho yodidi A, efuna umgangatho ophezulu wobuhle. Ezi zixhobo zichanekile{1}}zidityanisiwe ukusuka kwiileya ezininzi zentsimbi yegalvanized (ngokuqhelekileyo ukusuka ku-0.6mm ukuya kwi-1.2mm ubukhulu).

Umgangatho wokuwelda awubalulekanga kuphela kwimfezeko yolwakhiwo kodwa ukwachaphazela ngokuthe ngqo ukutywinwa kwesithuthi, ukusebenza kwe-acoustic, kunye nesibheno sokugqibela sokubonwayo.

Kwimveliso yemveli, usebenzisa i-AC eqhelekileyooomatshini bokuwelda amabalakuba udibaniso lomnyango lunemingeni emininzi ebalulekileyo:

1. Ukugxothwa kunye nokuNgeniswa:Uziro -indalo enqumlayo ye-AC yangoku ikhokelela kugalelo lobushushu obungazinzanga, ibangela ukugxothwa kwe-weld (spatter) enamathela kwimigangatho yodidi A. Ngaphaya koko, ukujongwa komphezulu onzulu konyusa kakhulu ixabiso lokusila ngeposi-lokuyilungisa.
2. IiNuggets ezingangqinelaniyo:Impendulo yangoku eqhwalelayo ikhokelela ekudibaneni okulambathayo kobukhulu be-weld nugget kunye nokomelela kwiipleyiti ezininzi{0}}ezibhityileyo, ezinokukhokelela kwizikhalazo ezisemgangathweni ezifana nokuvuza kwamanzi okanye ingxolo engaqhelekanga yekhabhini.
3. IiBottlenecks zexesha lokujikeleza:Imijikelo emide yokukhutshwa koomatshini be-AC iyasokola ukuhlangabezana neemfuneko zetempo eziphezulu-zeendlela zala maxesha zokuvelisa iimoto (umz., Ngaphantsi okanye ilingana nemizuzwana engama-45 ngeyunithi nganye).

Ukufezekisa "i-zero egxothiweyo, i-deformation ephantsi, kunye nokuhambelana okuphezulu" ngesantya esiphezulu semveliso, i-Medium Frequency Direct Current (MFDC) koomatshini be-welding welding baye baba ngumgangatho woshishino lwehlabathi. I-Wuxi Haifei Welding Equipment Co., Ltd. iqinisekise ixabiso letekhnoloji ye-MFDC kuwo wonke amanqanaba amathathu angundoqo ngokuphunyezwa ngempumelelo kwii-OEM ezininzi zasekhaya nezamazwe ngamazwe.

Iipaneli zocango lwangaphandle zikufuphi{0}}nokunyamezelana ukugxothwa kweweld. Oomatshini bokuwelda amabala be-MFDC bajongana nalo mba kwinqanaba lawo elisisiseko ngomgaqo wabo wokusebenza owahlukileyo.

Iziweldi ze-AC zesiNtu (50Hz/60Hz) zivelisa i-sine wave current ewela i-zero kabini kumjikelo ngamnye. Oku kubangela ukuguquguquka okubalulekileyo kwigalelo lobushushu kunye nokungazinzi kwamandla{3}}abaqhubi abaphambili bokugxothwa kwe-weld.

• Ubuchwephesha be-MFDC Inverter: oomatshini bokuwelda bendawo be-MFDC balungisa amandla angenayo e-AC kwaye basebenzise inverter ukuyiguqula ibe phezulu-i-frequency AC (1000Hz okanye ngaphezulu), ethi iphinde ilungiswe kwakhona ibe yimveliso ye-DC egudileyo. Lo -ubuxhakaxhaka be-DC obuphezulu bususa i-zero-indawo yokunqumla, iqinisekisa igalelo lobushushu eliqhubekayo noluzinzileyo.
• Multi{0}}Inqanaba lolawulo lwamaza: iHaifei's MFDC oomatshini bokuwelda indawo baxhasa inkqubo-yenqanaba lamaza amaninzi (umzekelo,-ubushushu, i-Main Weld, kunye ne-Tempering).

1. {0}}ubushushu bangaphambili: Inqanaba eliphantsi{1}langoku elithambisa ubuso boqhagamshelwano kwaye licuthe umothuko wokuqala we-thermal.
2. I-Main Weld:{0}}uchaneko oluphezulu, unikezelo lwangoku oluzinzileyo ukwenza i-weld nugget efanayo.
3. Ukufudumeza: Irempu yangoku elawulwayo{0}ezantsi eyehlisa isithuba-noxinzelelo lwe-weld, icuthe ngakumbi i-deformation kunye nobunzulu bokungena.

Eli nqanaba lolawulo lwegranular linciphisa ukugxothwa ngaphezu kwe-85%, livumela izikhululo ezininzi ze-welding emnyango ukuphelisa inkqubo yokusila ngokupheleleyo. Amacandelo angahamba ngokuthe ngqo kwivenkile yepeyinti, ukunciphisa kakhulu iindleko zokuvelisa.

Ngokusebenzisa amaxesha amafutshane welding kunye nozinzo lwangoku ngakumbi, MFDC oomatshini ukuvumela unyuso oluphuculweyo electrode, ngokufanelekileyo ukulawula ubunzulu post{0}}weld indentations.

Omnye umceli mngeni wokuwelda ucango kukudityaniswa kweepleyiti ezicekethekileyo ezininzi-(umzekelo, 0.7mm + 0.9mm). Ezi zixhobo zincinci zinobulukhuni obuphantsi kwaye zifuna ulawulo oluchanekileyo kakhulu kuxinzelelo kunye nokufuduka ngexesha lenkqubo ye-welding.

I-welds ebandayo kunye nee-nuggets ezingahambelani zihlala zivela xa i-electrode ikhupha ngaphambi kokuba i-workpiece ixininiswe ngokupheleleyo.

• IiSeva zokufuduswa kwe-Electrode:Isixhobo seHaifei sidibanisa-izinzwa ezichanekileyo zokufuduka ukuze kuphunyezwe "cofa{1}}kuqala, ukukhupha{2}}kamva" kuvalwe{3}}ulawulo lwelophu. Inkqubo ihlola ukuhamba kwe-electrode ngexesha lokwenyani{5}, iqinisekisa ukuba i-welding current iqala kuphela emva kokuba izikhewu zisusiwe kwaye noxinzelelo oluseti lufikelelwe.
• Ukuphindaphinda amandla:Ulawulo oluphezulu-loluchanekileyo loomatshini be-MFDC luqinisekisa ukuphindaphindwa kwamandla ngaphakathi ±2%. Oku kuhambelana sisiseko somgangatho we-weld nugget.

IiOEM zeemoto zifuna ngqongqo, imigangatho enokulinganiswa kumgangatho weweld.

• Amaxabiso e-CPK:I-CPK (I-Index ye-Process Capability Index) ye-weld nugget ye-diameter yi-metric engundoqo yokuhambelana. Ngokulawulwa kwe-MFDC, i-CPK ye-nugget ye-nugget ingazinzisa kwi-Greater than or ilingana ne-1.67 (inqanaba lekhwalithi ye-Sigma ezintandathu), igqithise kakhulu imfuno yoshishino eqhelekileyo ye-1.33.
• Amandla e-Shear:Amandla omatshini we-weld kufuneka ahlangabezane neenkcukacha zoyilo. Iintsimbi zomnyango zifuna amandla okucheba kaKhulu kuno okanye alingana ne-4.5kN. Oomatshini bokuwelda indawo be-MFDC bahlala behlangabezana kwaye bagqithise lo mgangatho, beqinisekisa-ukuthembeka kolwakhiwo lwexesha elide locango.

Kwimigca yemveliso ezenzekelayo, umatshini wokuwelda kufuneka ungqamanise ngokugqibeleleyo-neirobhothi zesantya esiphezulu ukuhlangabezana namaxesha anzima womjikelo.

Umnyango wemoto oqhelekileyo unamanqaku angama-30-50 we-weld, efuna ixesha lokujikeleza elipheleleyo elingaphantsi kwemizuzwana ye-45. Oku kuthetha ukuba ixesha eliphakathi kwiweld nganye-kuquka ukubeka, ukuwelda, kunye nentshukumo yerobhothi{5}}kufuneka ibe malunga nomzuzwana omnye.

• Ukukhutshwa ngokukhawuleza kunye nokutshaja:Oomatshini be-welding be-Haifei MFDC babonisa umjikelezo wokukhupha ngokukhawuleza njengemizuzwana eyi-0.6 kunye nenkxaso "yokutshaja ngexesha lokunyakaza." Ngelixa irobhothi isuka kwindawo A ukuya kwindawo B, i-welder igqibezela umjikelo wayo wokutshaja, ivumela ukuba ikhuphe ngokukhawuleza xa ifika kwindawo B. Oku kunciphisa kakhulu ixesha elingelona{3}}i-welding.
• Udibaniso olungenamthungo:Isixhobo sibonelela ngonxibelelwano olusemgangathweni lweProfinet okanye ye-EtherNet/IP yonxibelelwano oluphezulu-olukhawulezayo, olungenamthungo kunye neenkqubo ezinkulu zerobhothi zamashishini ezifana neFANUC, ABB, kunye neKUKA.

Uphononongo lwemeko oluvela kumgca omkhulu wemveliso wocango lwe-OEM lubonise:

• Ukwandiswa kwamandla:Ngenxa yezantya zomjikelo ophezulu kunye nokuthembeka, enye-umthamo weshift wonyuke nge-18%.
• Ugcino lweendleko:Ngokuncipha okukhulu kokugxothwa kunye nokusebenza kwakhona, iindleko zomsebenzi wonyaka kunye nokulungiswa kwancitshiswa ngaphezulu kwe-85,000 yeedola (malunga . 600,000 RMB).
• OEE Metrics:Sisonke isiXhobo esiFanelekileyo sizinzile ngaphezu kwe-90%.

Ukwenziwa kweemoto zale mihla kufuna ukulandeleka ngokupheleleyo komjikelo wobomi bomgangatho wemveliso.

• VIN -iNqanaba lokuGcina uVimba:Zonke iiparameters ze-welding (okwangoku, i-voltage, ixesha, ukufuduka) zigcinwa ngokuzenzekelayo yi-VIN (iNombolo yeSaziso seMoto) kwaye igcinwe kwindawo okanye ilayishwe kwi-MES.
• Ulungele uPhicotho-zincwadi:Ngexesha lophicotho lomgangatho we-OEM, inkqubo inokubuyisa ngoko nangoko idatha yembali kuyo yonke i-weld enye kuwo nawuphi na umnyango onikiweyo. Oku kubonelela ngekhonkco elipheleleyo lobungqina obusemgangathweni, ukuqinisekisa ukuba inkampani idlula ngokulula uphicotho olungqongqo.

Ukuqukumbela

Ukusetyenziswa koomatshini bokuwelda indawo be-MFDC kwimveliso yocango lweemoto kungaphezulu nje kokuphuculwa kobugcisa; kukutsiba kwifilosofi esemgangathweni. Iguqula iwelding ukusuka kumngcipheko ophezulu-ophezulu,{2}}umsebenzi owenziwe ngokutsha ube ngumsebenzi{3}}ochanekileyo, othelekelelwayo ozenzekelayo.

Oomatshini bokuwelda indawo ye-Haifei MFDC, kunye nolawulo oluchanekileyo lobushushu, ungqamaniso olukrelekrele, kunye nokulandeleka ngokupheleleyo, ngamaqabane aphambili ekuphumezeni umgangatho ophezulu{0},{1}ophezulu{1}}ukwenziwa kocango olusebenzayo{2}}ukunceda abavelisi ukuba bahambe ukusuka nje "ukubamba iinxalenye kunye" ukuya ekuphumezeni "umgangatho ongabonakaliyo."
