A ukuchasa umatshini weldingidibanisa iinxalenye zentsimbi ngokugqithisa umbane olawulwayo ngokudibeneyo ngelixa ii-electrode zisebenzisa amandla. Ukumelana nombane kuvelisa ubushushu obugxininisiweyo kwi-interface yoqhagamshelwano, kwaye amandla asetyenziswayo anceda ukwenza kunye nokudibanisa i-weld. Ngokuxhomekeke kuyilo oludibeneyo kunye ne-electrode, izixhobo zinokwenza indawo, iprojekti, i-seam okanye i-butt welding, ngokuqhelekileyo ngaphandle kocingo lokuzalisa.
Le nkqubo isetyenziswa ngokubanzi kwimveliso yoshishino kuba umjikelo we-welding unokuphindwa phantsi kwezicwangciso ezilawulwayo. Nangona kunjalo, ukukhetha umatshini ngomthamo we-transformer kuphela kukhokelela kwiziphumo ezibi. Izinto eziphathekayo, ukwambathisa, ubukhulu, uyilo oludibeneyo, ukufikelela kwi-electrode, indlela yokwamkelwa kwe-weld kunye nemveliso yemveliso zonke kufuneka ziqwalaselwe kunye.
Yintoni i-Resistance Welding?
I-Resistance welding liqela leenkqubo zokujoyina ezisebenzisa ukuxhathisa kombane ukuvelisa ubushushu okanye kufutshane nojongano phakathi kwamalungu esinyithi. Izixhobo zokusebenza zibanjwe kunye ngee-electrode okanye i-clamps ngelixa i-current ihamba kwi-welding circuit.
Ubudlelwane obusisiseko budla ngokubonakaliswa ngolu hlobo:
- Q=I²Rt
Apho:
- Qbubushushu obuveliswayo.
- Ingumsinga wokuwelda.
- Rkukuxhathisa kombane kwisekethe nakwi-interfaces zoqhagamshelwano.
- tlixesha-langoku.
Inxaki inceda ukucacisa ukuba kutheni i-welding yangoku inefuthe elingako ekwenziweni kobushushu, kodwa ayingomatshini opheleleyo-useta ifomula. Ukumelana nokutshintsha ngexesha le-weld, kunye nesiphumo sokugqibela sikwachatshazelwa ngamandla e-electrode, indawo yoqhagamshelwano, i-conductivity yezinto eziphathekayo, ukugubungela umphezulu, ukufaneleka - phezulu, ukupholisa kunye nemeko ye-electrode.
Uninzi lweenkqubo ze-welding zesiqhelo azifuni ucingo lwe-welding, i-flux okanye igesi yokukhusela. Oko akuthethi ukuba yonke intsimbi eqhubayo kulula ukuyidibanisa. Ubhedu kunye ne-aluminiyamu, umzekelo, ziqhuba ubushushu kunye nombane ngokukhawuleza, ngoko ke indawo edibeneyo, i-electrodes, umthombo wamandla kunye neshedyuli ye-welding ifuna isicelo{2}}uvavanyo oluthile.
Usebenza Njani umatshini wokuWelding weResistance?
Umjikelo we-welding oqhelekileyo uquka ukubeka, ukukhama, ukuhamba kwangoku, ukubamba kunye nokukhulula. Inqanaba ngalinye linefuthe elithe ngqo kwi-weld consistency.
1. IiNdawo zokuSebenza zimi
Amalungu abekwe phakathi kwee-electrode okanye ngaphakathi kwezixhobo ezinikezelweyo. Ukuma okulungileyo kugcina indawo ye-weld, i-overlap kunye nemeko yoqhagamshelwano iphinda iphindwe. Ukuba i-sheet -indibano yentsimbi inomsantsa omkhulu okanye ihamba ngexesha lomjikelo, ukwandisa i-welding current inokuyifihla ingxaki okwethutyana kodwa ayiyi kulungisa imeko edibeneyo.
2. I-Electrodes iSebenzisa amandla
Ii-electrode zivala kwaye zibambe ii-workpieces ngaphambi kokuba kusetyenziswe okwangoku. Eli khefu libizwa ngokuba lixesha lokucudisa. Amandla afunekayo axhomekeke kwizinto eziphathekayo, ubukhulu, indawo edibeneyo, i-geometry yokubonisa kunye nenkqubo ye-welding.
Amandla angonelanga anokuba negalelo kwi-arcing okanye ukugxothwa. Amandla agqithisileyo anokunciphisa ukuxhathisa koqhagamshelwano okanye ukuguqula uqikelelo phambi kokuba ubushushu obaneleyo buphuhliswe. Okwangoku kunye nokunyanzeliswa kufuneka kumiselwe njengeshedyuli ye-welding ehambelanayo.
3. Ngoku Udlula ngokudibeneyo
Umlawuli uthumela ngoku ngokusebenzisa i-electrodes kunye ne-workpieces ngexesha elichaziweyo. Ubushushu bukhula apho ukuxhathisa kombane kugxininiswe. Kwiwelding yendawo, oku kuqhele ukwenza i-weld nugget yendawo phakathi kwamaphepha adlulanayo. Kwi-welding yeprojekithi, iprojekti eyenziweyo igxininisa ngoku kunye nokunyanzeliswa kwindawo ekhethiweyo.
4. Iifom ze-Weld phantsi koBushushu kunye noxinzelelo
Umdibaniso ovuthayo uqulethwe ngamandla e-electrode. Inqanaba langoku, ixesha le-weld kunye namandla kufuneka lenze isandi esidibeneyo ngaphandle kokutshiza okugqithisileyo, ukunyanzeliswa komphezulu okanye umonakalo kwi-coating workpiece.
5. Umdibaniso ubanjwe phambi kokukhululwa
Emva kokuyeka kwangoku, ii-electrodes zihlala zivaliwe ixesha elifutshane lokubamba. Umdibaniso upholisa kwaye udibanise phantsi koxinzelelo phambi kokuba i-workpiece ikhululwe. Ukukhulula kwangethuba kakhulu kunokuchaphazela umdibaniso, ngakumbi xa inxalenye okanye isilungiso sinokuhamba ngelixa i-weld isatshisa.
Izahlulo eziPhambili zoMshini wokuWelding we-Industrial Resistance
Isakhelo somatshini siyinxalenye enye yenkqubo yokuwelda. Ukuseta imveliso ethembekileyo ngokuqhelekileyo kubandakanya:
