Kwimveliso yanamhlanje,iphakathi-i-frequency (MFDC) spot welderiye yaba sisisombululo esingundoqo sokuwelda kuzo zonke iimoto, izixhobo zasekhaya, izinto zombane, kunye nemizi-mveliso ye-aerospace. Ibalasele kungekuphela nje ngokuhambelana kwayo okubanzi kodwa nokusebenza kwayo okuphezulu, ukungaguquguquki kwe-welding, kunye nokusebenza kokugcina amandla{1}}.
Eli nqaku lihlalutya nzulu ukuba kutheni i-MFDC i-spot welders inikezela ngolungelelwaniso oluphawuleka ngolo hlobo, luxhaswa lulwazi olugunyazisiweyo kunye nokuqonda okuhambelana nomgangatho ophezulu{0}}nomxholo woshishino kuGoogle.
IMathiriyeli eBanzi kunye nokuTyaniswa koButyetye
I-MFDC spot welders ziyilelwe ukuphatha uluhlu olubanzi lwemathiriyeli:
- Iindidi ezininzi zentsimbi:{{0}intsimbi yekhabhoni ephantsi, intsimbi engatyiwa, intsimbi, iialloyi zealuminiyam, kunye nengxubevange yobhedu.
- Ilungele iworkpieces ezibhityileyo nezityebileyo:Uhlengahlengiso lwangoku, amandla, kunye nexesha livumela ukuwelda okuthembekileyo kuluhlu olubanzi lokutyeba.
- Igqwesile kwi{0}}yokuqhuba okanye imathiriyeli egqunyiweyo:isebenza ngokukhethekileyo kwintsimbi ekhandiweyo, amakhasi amaninzi, kunye -nobushushu obuphezulu{1}}nezintsimbi eziqhubayo ezifana ne-aluminiyam-izinto ezihlala zicela umngeni kwiiwelda ze-AC.
- Ixhasa iinkqubo ezininzi ze-welding:kubandakanywa i-spot welding, i-projection welding, i-seam welding, kunye ne-pulse welding.
Oku kusebenziseka kubanzi kwenza abashiseli bamabala be-MFDC bakwazi ukuhlangabezana neemfuno zezinto ezahlukeneyo neziphuhlayo zemathiriyeli yale mihla.
Inkqubo yeWelding echaneke kakhulu kwaye iyalawuleka
Iisistim ze-MFDC zisebenzisa itekhnoloji yoguqulo oluphambili ukuguqula i-AC ibe yi-1–4 kHz medium-i-frequency DC, ibangele:
- Izinzile, i-ripple{0}imveliso yasimahla:Zero reactance kunye ne-DC ezinzileyo imveliso yangoku egxininisiweyo kunye negalelo lobushushu elizinzileyo.
- I-Milisecond{0}}inqanaba lolawulo lwe-welding:Amaxesha amafutshane kakhulu e-welding kune-welders ye-AC yendabuko, alungele amacandelo achanekileyo.
- Okulungileyo-iparamitha zewelding:lokwenyani{0}}ulawulo lwexesha lwangoku, amandla welding, ixesha, kunye nohlobo lwamaza luqinisekisa ukungaguquguquki.
- Ukujongwa komgangatho oguqukayo:-Isiphelo esiphezulu se-MFDC welders isici esivaliweyo -ulawulo lwe-loop, imbuyekezo ezenzekelayo, kunye-nexesha lokwenyani lokujongwa kweparamitha ukugcina ukungaguquguquki kwe-weld.
Ezi zakhono ziqinisekisa ukuchaneka okugqwesileyo kunye nokuphinda-phinda, okubaluleke ngakumbi -kwivolyum okanye ephezulu{1}}echanekeko iindawo zemveliso.
UkuSebenza okuPhakamileyo koMbane kunye neGridi{0}Umsebenzi oLungeneyo
Abashiseli bamabala beMFDCzigqwesa kakhulu iziweldi ze-AC zemveli ekusebenzeni kakuhle kwamandla:
- Umba wamandla ukuya kuthi ga kwi- ~ 98%:xa kuthelekiswa malunga ne-0.6 yee-welders ze-AC, inciphisa kakhulu ilahleko yamandla asebenzayo.
- Ukongiwa kwamandla ~30%:enkosi kubushushu obugxininisiweyo, imijikelo yokuwelda emifutshane, kunye nemveliso esebenzayo yeDC.
- Iimpembelelo ezincitshisiweyo kwigridi yamandla:igalelo lesigaba sesithathu-esilungelelanisiweyo, imfuno ephezulu esezantsi, kunye nokusebenza okuzinzileyo phantsi kweemeko zobonelelo eziguquguqukayo.
- Imveliso ephezulu yemveliso:imijikelo ye-weld efinyeziweyo ivumela i-welds ezininzi ngomzuzu.
Kwiifektri ezijongene nokunyuka kweendleko zamandla, i-MFDC welding ibonelela ngenzuzo yezoqoqosho ngokuthe ngqo.
Umgangatho weWelding oZinzileyo kunye neMveliso eNgcono yokusiNgqongileyo
Abashiseli bamabala beMFDC bamkelwa:
- Iintsika ze-weld ezifanayo ezinamandla amakhulu:ngenxa yemveliso ye-DC ezinzileyo kunye negalelo lobushushu elingaguqukiyo.
- Isitshizi esincinci kunye nokuncitshiswa kokuhlehlisa:kubalulekile kumashishini aneemfuno ezingqongqo zomgangatho womphezulu.
- Ukusebenza okugqwesileyo -kwintsimbi yokuqina, intsimbi, nealuminiyam:ezisetyenziswa kakhulu kukukhanya kwemoto kunye -nosetyenziso olutsha lwamandla.
- Ukuhambelana okugqwesileyo kunye ne-automation:Iinguqu ze-MFDC zihlangene kwaye zikhaphukhaphu, zinciphisa umthwalo kwiingalo zerobhothi kunye nokuphucula ukuthembeka.
Isitshizi esisezantsi, ingxolo encitshisiweyo, kunye nokuphazamiseka okuncinci kwe-thermal nako kudala indawo yokusebenza ecocekileyo nekhuselekileyo.
Yenzelwe iMveliso yangoku - Ukuzenzekela, ubukrelekrele, kunye nokuguquguquka
