Ubuchwepheshe be-high-frequency welding yepayipi yensimbi ye-arc engaphansi

1. Ukulawulwa kwegebe le-weld: Ngemva kokugoqa ngama-rollers amaningi, insimbi ye-strip ithunyelwa kuyunithi yepayipi elishiselwe. Insimbi ye-strip igoqwa kancane kancane ukuze yakhe ishubhu eliyindilinga elingenalutho elinesikhala samazinyo. Lungisa inani elicindezelayo lerola yokukhama ukuze ulawule igebe lokushisela phakathi kuka-1 no-3 mm futhi wenze iziphetho zokushisela ziguqe. Uma igebe likhulu kakhulu, umphumela wokusondeza uzoncishiswa, i-eddy current ishoda, futhi amakristalu e-weld azoxhunywa ngokuqondile kabi futhi angaxhunywanga noma aqhekeke. Uma igebe lincane kakhulu, umphumela wokusondeza uzokwanda, ukushisa kwe-welding kuyoba kukhulu kakhulu, futhi i-weld izoshiswa; mhlawumbe i-weld izokwakha umgodi ojulile ngemuva kokukhishwa nokugoqa, okuzothinta ukubukeka kwe-weld.

2. Ukulawula izinga lokushisa lokushisela: Ngokusho kwefomula, izinga lokushisa lokushisela lithintwa amandla okushisa amanje e-eddy e-high-frequency. I-high-frequency eddy amandla okushisa amanje athintwa imvamisa yamanje, futhi amandla okushisa amanje e-eddy alingana nesikwele semvamisa yamanje yesikhuthazo; futhi imvamisa yamanje yesikhuthazo ithonywa i-voltage ekhuthazayo, yamanje, i-capacitance, kanye ne-inductance. I-inductance = i-flux kazibuthe/okwamanje Efomini: f-khuthaza imvamisa (Hz-khuthaza amandla ku-loop (F capacitance = ugesi/voltage; L-khuthaza i-inductance ku-loop. Imvamisa yokukhuthaza ihambisana ngokuphambene namandla kanye namandla futhi impande yesikwele ye-inductance ku-loop yesikhuthazo Ingase ilingane nempande yesikwele ye-voltage kanye ne-current. Ukufinyelela umgomo wokulawula izinga lokushisa lokushisela, izinga lokushisa lokushisela lilawulwa ku-1250 ~ 1460 ℃, lingahlangabezana nezidingo zodonga lwepayipi lokungena kwe-3 ~ 5mm Ijubane lokushisela. lapho ukushisa okokufaka kuntuleka, umkhawulo we-weld evuthayo uzodlula izinga lokushisa lokushisela, okubangela ukushisa ngokweqile noma amaconsi, okubangela ukuthi i-weld yakhe imbobo encibilikisiwe.

3. Ukulawulwa kwamandla okucindezela: ngaphansi kokucindezela kwe-roller yokucindezela, imiphetho emibili ye-tube engenalutho iyashiswa ekushiseni kwe-welding. Izinhlamvu zekristalu yensimbi ezizimonyo ndawonye zingena futhi zicwebezele zodwa, futhi ekugcineni zakhe ukushisela okuqinile. Uma amandla e-extrusion amancane kakhulu, inani lamakristalu lizoba lincane, futhi amandla ensimbi ye-weld azokwehla, futhi imifantu izokwenzeka ngemva kokusetshenziswa kwamandla; uma i-extrusion force inkulu kakhulu, insimbi encibilikisiwe izocindezelwa ngaphandle kwe-weld, ingancishiswa kuphela Amandla we-weld ayathuthukiswa, futhi kuzokwenzeka izindawo eziningi kanye nama-burrs angaphakathi, futhi ngisho nokukhubazeka okufana nama-weld lap joints kuyokwenzeka. kwakheka.

4. Ukulungiswa kokuma kwekhoyili ye-high-frequency induction: isikhathi sokushisa esisebenzayo side, futhi i-high-frequency induction coil kufanele ibe seduze ngangokunokwenzeka endaweni ye-squeeze roller. Uma i-loop yokungeniswa ikude ne-squeeze roller. Indawo ethinteke ukushisa ibanzi futhi amandla e-weld ancishisiwe; ngokuphambene nalokho, unqenqema lwe-weld alukho ukushisa, okuholela ekubunjweni okungalungile ngemva kokukhishwa. Indawo ye-cross-sectional of resistor akufanele ibe ngaphansi kuka-70% wendawo yesiphambano se-diameter yangaphakathi yepayipi yensimbi. Umphumela wawo uwukwenza ikhoyili yokungeniswa, unqenqema lwepayipi lokushisela lingabi nalutho, futhi induku kazibuthe yakhe iluphu yokungeniswa kagesi.

5. I-resistor ingenye noma iqembu lezintambo ezikhethekile zamagnetic zamapayipi ashiselwe. . Umphumela wokusondela uyenzeka, futhi ukushisa kwamanje kwe-eddy kugxilwe eduze konqenqema lwe-weld yeshubhu elingenalutho ukuze unqenqema lweshubhu elingenalutho lushiselwe ekushiseni okushiselayo. I-resistor ihudulwa ngaphakathi kweshubhu ngentambo yensimbi, futhi indawo emaphakathi kufanele imiswe ngokuqhathaniswa eduze nendawo ephakathi kwerola yokuminyanisa. Uma uqala, ngenxa yokunyakaza okusheshayo kwe-tube engenalutho, idivayisi yokumelana igugile kakhulu ukungqubuzana kodonga lwangaphakathi lwe-tube engenalutho futhi idinga ukushintshwa njalo.

6. Izibazi zokushisela zizokwenzeka ngemva kokushisela nokukhishwa. Ukuthembela ekuhambeni okusheshayo kweipayipi lensimbi elishiselwe, isibazi sokushisela sizoba sicaba. Ama-burrs ngaphakathi kwepayipi elishiselwe ngokuvamile awahlanzwa.
