Intshayelelo: Ulungelelwaniso phakathi kokuSebenza ngokuSebenzayo kunye noKhuseleko
Kwisixhobo esitsha sokuvelisa ibhetri yemoto yamandla, ngelixa amedium frequency spot welderigqiba indawo ye-weld kwimizuzwana eyi-0.3, ubushushu be-electrode bukhuphuka buthule ukuya kuma-400 degrees; Kwicwecwe lesixhobo sokuwelda intsimbi, umzuzu xa i-3000A yangoku ingena ngokuchanekileyo kwishiti lentsimbi, amandla ombane wemitha ye-electromagnetic afikelela kumaxesha angama-50 ezixhobo zasekhaya eziqhelekileyo. La manani asikhumbuza ukuba usetyenziso olukhuselekileyo lwezixhobo zokuwelda zebala eliphakathi, "iipeni ze-welding ezichanekileyo" zemveliso yanamhlanje, ngumceli mngeni wobugcisa kunye nobugcisa bolawulo.
I. Ukubeka iSiseko soKhuseleko phambi kokuSebenza
UkuJonga izixhobo eziBanzi
Ngaphambi kokuba uqale imedium frequency spot welder, "inqaku{0}}ezintathu" kufuneka lenziwe:
- Ukuqinisekiswa kweInsulation:Sebenzisa i-500V megohmmeter ukuvavanya ukuchasana kwe-insulation, uqinisekisa ixabiso eliKhulu okanye elilingana ne-5MΩ (nge-IEC 60974-1 eqhelekileyo).
- UQinisekiso lokuQala:Sebenzisa umvavanyi wokumelana nomhlaba ukuqinisekisa ukuxhathisa komgca we-PE ngaphantsi okanye okulingana ne-4Ω.
- Ukupholisa uQinisekiso:Khangela ukuba izinga lokuhamba kwenkqubo yokupholisa amanzi lizinzile kwi-3-6L / min (lungisa ngokusekelwe kumandla wesixhobo).
- Iinkcukacha ezisuka kwinkampani yamalungu eemoto zibonisa: Amashishini abeka emgangathweni iitshekhi zokuqalisa anciphisa izinga lokusilela kwezixhobo ngama-67% kunye nokunxitywa kwe-electrode engaqhelekanga ngama-42%.
I-Scientific Parameter Calibration
Tshatisa iiparamitha zewelding kubukhulu bezinto:
- 0.5mm aluminium ialloy sheet: Ngoku ecetywayo 12-15kA, ixesha 8-12ms
- I-1.2mm ishidi lentsimbi yentsimbi: Kucetyiswa ngoku 18-22kA, ixesha le-15-20ms
- Umenzi wesixhobo sasekhaya usete ngendlela engafanelekanga imilinganiselo ye-1.5mm ebandayo{1}}yentsimbi eqengqelekayo (25kA/30ms), ebangela ukhukuliseko lwencam ye-electrode lukhawulezise amaxesha ama-3, okonyusa iindleko zokunxiba zonyaka nge-120,000 RMB.
Ulungelelwaniso lweSixhobo soKhuselo oluchanekileyo
Abaqhubi kufuneka banxibe:
- I-ANSI Z87.1 eqinisekisiweyo echasene{1}}nezibuko ze-spatter
- Ubushushu -buxhathisa (Mkhulu okanye bulingana nama-500 degree) iiglavu zesikhumba
- Impahla ekhuselayo enedangatye{0}}ireyithingi exhathisayo Inkulu kune okanye ilingana neNFPA 2112
- Uphando lwe-Japan Welding Engineering Society lubonisa: Ukunxiba okusemgangathweni kwezixhobo zokukhusela kunciphisa amathuba okutsha kwingozi nge-92%.
II. Ulawulo loKhuseleko Ngexesha lokuSebenza
Ulawulo lweNdlela yangoku echanekileyo
Gcina indawo yoqhagamshelwano rhoqo phakathi kwendawo yokusebenza kunye ne-electrode:
- Yitshintshe ingcebiso ye-electrode ngokukhawuleza ukuba ukunxiba kwedayamitha kungaphezulu kwe-15%
- Lawula impazamo yokubeka iworkpiece ngaphakathi kwe ±0.5mm
- Inkampani entsha yebhetri yamandla ifumene i-38% amandla e-weld asezantsi ngenxa yokunxiba kwencam ye-electrode (i-diameter enxitywayo ukusuka kwi-8mm ukuya kwi-6.2mm), ekhokelela kwilahleko yokukhumbula imveliso engaphezu kwezigidi ezi-5 zeerandi.
I-Active Thermal Cycle Intervention
- Misela isilumkiso sendlela yokuqokelela ubushushu:
- Misa imizuzu emi-5 yokupholisa emva kwee-welds ezingama-200 ezilandelelanayo
- Qalisa ukupholisa ngenkani ukuba ubushushu bomphezulu we-electrode bungaphezu kwe-150 degree
- Idatha ye-TÜV yesatifikethi se-Rheinland ibonisa: Ulawulo olufanelekileyo lomjikelo we-thermal unokwandisa ubomi be-electrode ngamaxesha angama-2.3.
IsiKhuseli soMbane woMbane oGuquzelayo
- Seta malunga nesixhobo:
- Amandla ommandla wemagnethi Ngaphantsi okanye alingana ne-100μT nge-1m ukusuka kwisixhobo (umgangatho we-ICNIRP)
- Ixabiso eliphezulu-lokuthotywa kwemitha yeradiyidi yokuthomalalisa Ixabiso elikhulu kuno okanye lilingana ne-30dB
- Umvelisi wesixhobo sonyango ufakele -ikhaka le-aluminiyam ephindwe kabini, ukunciphisa indawo yokusebenza ngemitha ukusuka kwi-85μT ukuya kuma-28μT, ehlangabezana neemfuno zonyango{3}}zemveliso yendalo.
III. Ingqinisekiso yoKhuseleko Emva kokuvalwa
Inkqubo yokuKhululwa koMgangatho waMandla
- Emva kokuvala isixhobo, kufuneka:
- Lindela i-capacitor bank auto{0}}ukukhupha ukuya ngaphantsi kwe-50V (ithatha ~3-5 imizuzu)
- Yenza ukukhutshwa kwesibini ngesandla usebenzisa intonga yokukhupha
- I-factory processing metal yenza i-200,000 RMB kwilahleko ngokuthe ngqo kwingozi yokutshatyalaliswa kombane ngenxa yokuba iinkqubo zokukhupha azizange zilandelwe.
Ulawulo loLondolozo lwamaxesha ngamaxesha
- Misela ishedyuli yotshintsho yecandelo eliphambili:
- Isihluzi senkqubo yokupholisa amanzi: Faka endaweni nganye iiyure ezingama-500
- Imodyuli yamandla: Hlola rhoqo iiyure ezingama-3000
- Ibhodi yesekethe yokulawula: Ukucoca uthuli rhoqo emva kweenyanga ezintandathu
- Umenzi wempahla emhlophe wandise i-MTBF (iXesha eliPhakathi kweFailures) ukusuka kwi-1200 ukuya kwii-2500 iiyure ngokwenza ukugcinwa okusemgangathweni.
Imeko{0}esekwe kwiNgxaki yokuPhendula ngoCwangciso
- Yenza uqheliselo olukhethekileyo lwenyanga:
- Impendulo kaxakeka yokuncamathela kwe-electrode (ukucima umoya ngokukhawuleza/amandla)
- Ukuphathwa okungxamisekileyo kokuvuza kwamanzi okupholisa (vula isekethe yokupholisa yokugcina)
- Umenzi wecandelo lenqwelomoya unciphise umndilili wexesha lokuphendula kwisehlo ukusuka kwimizuzu eyi-8 ukuya kwimizuzwana engama-90 ngokwenziwa kokulinganisa.
【Isiphelo: Ukhuseleko lilitye lembombo lokuzivelela kweTekhnoloji】
Njengokomedium frequency spot welders ikhefu 120 welds ngomzuzu kunye nolawulo igalelo ubushushu ifikelela 0.1% ukuchaneka, ixabiso iinkqubo zokusebenza ekhuselekileyo kude kudlule ukuthintela ingozi ngokwayo. Iinkampani ezinyanzelisa ngokungqongqo imigangatho yokhuseleko azigcini nje ukulawula izinga lokulimala ngaphantsi kwe-0.12 ‰ (umyinge we-industry 0.85 ‰) kodwa ziphucula ukusebenza kakuhle kwemveliso yonke nge-23% ngokuzinza kwezixhobo eziphuculweyo. Oku kuqinisekisa umgaqo ongunaphakade wokwenziwa kwemveliso: inkqubela phambili yetekhnoloji yokwenene ihlala yakhelwe kwisiseko solawulo olungqongqo lokhuseleko.
