Intshayelelo
Kwimveliso yemizi-mveliso,oomatshini bokuwelda indawo capacitorzisetyenziswa kakhulu kumhlaba wokuwelda ngentsimbi ngenxa yokusebenza kwawo okuphezulu kunye neempawu zogcino lwamandla-. Nangona kunjalo, ukusebenza kwezixhobo kuxhomekeke kwiinkqubo zokusebenza ezisemgangathweni. Eli nqaku liphonononga ngokucokisekileyo imiba yokusebenza koomatshini be-capacitor spot welding, ukusuka kulungiselelo lokhuseleko ukuya kwiinkcukacha zokugcinwa, ukukunceda ugqibezele imisebenzi ye-welding ngokufanelekileyo nangokukhuselekileyo.
I. ULungiselelo loKhuseleko Phambi Kokusebenza
1.Ukuhlolwa kwendalo
- Qinisekisa ukuba indawo yokusebenza ingena umoya-kakuhle kwaye igcinwe kude kwizinto ezinokutsha neziqhumayo (ezifana nepetroli, utywala, njl.njl.) ukunqanda imililo ebangelwa kukutshiza kwe welding.
- Jonga ukuba amandla ombane ayazifezekisa na iimfuno zesixhobo (ngokwesiqhelo esithathu-isigaba esingu-380V), kwaye uqinisekise ukuba uqhagamshelo locingo olusemhlabeni lukhuselekile ukunqanda iingozi zokothuka kombane.
2.Ukhuseleko lomntu
- Abanini-zithuthi kufuneka banxibe iiglasi zokhuselo, iiglavu ezigqunyiweyo, kunye nempahla{0}}ekwaziyo ukumelana nobushushu ukunqanda ukutsha kwamaqondo obushushu aphezulu okanye ii-arcs ngexesha lokuwelda.
- Ukuba umsi kunye nothuli ziveliswa ngexesha lenkqubo ye-welding, kuyacetyiswa ukuba ugqoke isiphepheli sokuphefumula ukuqinisekisa ukhuseleko lokuphefumula.
3.Ukuhlolwa kweZixhobo
- Jonga ukuba iingcebiso ze-electrode, iintambo, kunye nezihlanganisi zinxibile okanye zophukile, uqinisekise ukuba umphezulu we-electrode ucocekile kwaye awunamaleko e-oxide.
- Cima isitshixo samandla phambi kokunika amandla kwaye usete imowudi ye-welding ukuba "ikhuphe" imeko ukunqanda ukusebenza ngengozi.
II. Ukusetwa kweParameter kunye nokuSebenza kwe-Welding
1.Uhlengahlengiso lweParameter
- Ngokusekelwe kwizinto zokusebenza (ezifana nensimbi engenasici, i-alloy yobhedu) kunye nobukhulu, lungisa umbane wokutshaja (ngokuqhelekileyo phakathi kwe-10-30kV) kunye noxinzelelo lwe-electrode ngokusebenzisa ipaneli yokulawula.
- Kwizinto zeplate ezincinci, kucetyiswa ukuba kusetyenziswe i-voltage ephantsi kunye nexesha elifutshane lokukhupha (njengemizuzwana ye-0.003-0.005) ukuphepha ukunyibilika okugqithisileyo; iipleyiti ezishinyeneyo zifuna amandla ombane aphezulu kunye nexesha elandisiweyo lokukhutshwa.
2.Amanyathelo okuWelding
- Beka i-workpiece phakathi kwe-electrodes ephezulu nangaphantsi, uqinisekise ukuba iindawo zokubonisa zihambelana ngokupheleleyo ne-electrodes.
- Isinyathelo sokutshintsha unyawo, izixhobo zikhupha ngokukhawuleza amandla e-capacitor ukugqiba i-welding. Gcina uxinzelelo lwe-electrode efanayo ukuze ugweme ukuphambuka kwinqanaba le-weld okanye i-welding ebuthathaka.
- Emva kokuba i-welding igqityiwe, linda ukuba i-workpiece ipholile (malunga ne-10-15 imizuzwana) ngaphambi kokususwa ukukhusela ukutshisa.
III. Thumela-uLondolozo lokuSebenza kunye neMiqathango
1.Ukucocwa kweMihla
- Coca i-electrode surface spatter emva kokusetyenziswa ngakunye, usebenzisa amavili okusila okanye izixhobo ezikhethekileyo zokunxiba ukugcina ukuhanjiswa.
- Jonga ukuba isekethi yamanzi okupholisa icacile, buyisela izihluzi ngokukhawuleza ukuthintela ukuvaleka kwesikali.
2.ULondolozo lwarhoqo
- Ukuhlolwa kwenyanga yeebhanki ze-capacitor kunye ne-transformer terminals, ukuqinisa i-screws ekhululekile ukuphepha ukudibanisa kakubi.
- Ukuba isixhobo sisebenza ixesha elide, sebenzisa i-anti{0}}i-oyile yokurusa kwii-electrode kunye neengalo ezisebenza ngomatshini ukunqanda ukubola kwe-oxidation.
3.Ukuphatha ngokungaqhelekanga
- Ukuba i-electrode incamathela okanye i-weld points ebuthathaka iyenzeka, zama ukunciphisa i-voltage okanye ukwandisa uxinzelelo lwe-electrode.
- Kwimeko yokusilela kwezixhobo (ezifana nokungahambi kakuhle kwamandla, i-alarm prompts), ngoko nangoko unqumle umbane kwaye uqhagamshelane nabasebenzi bolondolozo lweengcali.
Ukuqukumbela
Ukusebenza koomatshini be-capacitor welding spot kufuna ukulinganisa ukusebenza kakuhle kunye nokhuseleko. Inyathelo ngalinye, ukusuka kulungiselelo lokusingqongileyo ukuya kwiparameter debugging, kwaye emva koko ukuya kugcino lwamva, luchaphazela ngokuthe ngqo umgangatho we-welding kunye nobomi besixhobo. Ngokumisela iinkqubo zokusebenza, ayipheleli nje ekuphuculeni imveliso, kodwa amazinga okusilela nawo anokuncitshiswa, edala ixabiso elikhulu kumashishini. Kwiinkalo ezifana namandla amatsha kunye nokuveliswa kweemoto, ukulawula iindawo eziphambili zokusebenzaoomatshini bokuwelda indawo capacitorlinyathelo eliphambili kwimveliso ehlakaniphile.
