Ukuveliswa kobushushu kunye neMiba ePhembelelayo kwi-Resistance Spot Welding Machines

I-Resistance spot welding yinkqubo yokudibanisa esetyenziswa ngokubanzi kumashishini ahlukeneyo, kuquka iimoto, i-aerospace, kunye nokuveliswa kombane. Ngethuba lenkqubo ye-welding, ubushushu buveliswa ngokuqinisekileyo, kwaye le mveliso yobushushu inokuchaphazela kakhulu umgangatho kunye nokunyaniseka kwe-weld. Kweli nqaku, siza kuphonononga iindlela zokuvelisa ubushushu kumatshini we-welding wokumelana kunye nokuvavanya izinto eziphambili eziphembelela le mveliso yobushushu.

IiNdlela zokuVelisa ubushushu

Kwindawo yokumelana ne-welding, i-workpieces ezimbini okanye ngaphezulu zetsimbi zidityaniswa ngokufaka uxinzelelo kunye nokugqithiswa kombane ophezulu kwiindawo zoqhagamshelwano. Ubushushu buveliswa ikakhulu ngenxa yezi ndlela zilandelayo:

1. Ukumelana nokufudumeza: Njengoko umbane wombane uhamba ngeengcezu zetsimbi, ukuchasana kwezinto kuvelisa ukushisa. Olu bushushu luhambelana ngokuthe ngqo nokuchasana kwezinto kunye nesikwere sokudlula ngoku, njengoko kuchazwe ngumthetho kaJoule.
2. Qhagamshelana Ukumelana: Ukuchasana koqhagamshelwano phakathi kwe-electrode kunye ne-workpiece nayo igalelo ekuveliseni ubushushu. Ichaphazeleka yimeko yomhlaba, ukucoceka, kunye noxinzelelo olufakwe kwindawo yokudibanisa.
3. Ilahleko yeHysteresis: Kwimathiriyeli ye-ferromagnetic, njengentsimbi, ukulahleka kwe-hysteresis kwenzeka ngenxa yotshintsho olukhawulezayo kumandla ombane owenziwe ngumbane otshintshayo. Le lahleko ibangela ukuveliswa kobushushu okongeziweyo.

Imiba Enempembelelo

Izinto ezininzi zinokuphembelela ubungakanani bobushushu obuveliswe kwindawo yokumelana ne-welding:

1. I-Welding yangoku: Ukwandisa i-welding current kuya kukhokelela kwisizukulwana esiphezulu sokushisa ngenxa yobudlelwane obuthe ngqo phakathi kwangoku kunye nobushushu.
2. I-Electrode Force: Amandla aphezulu e-electrode anokunyusa ukuveliswa kobushushu ngokuphucula uqhagamshelwano phakathi kwe-electrode kunye nezinto zokusebenza.
3. Izinto ze-Electrode: Ukukhethwa kwezinto ze-electrode kunokuchaphazela kakhulu ukuveliswa kobushushu. Ii-electrodes ezenziwe ngezinto ezinokumelana nombane okuphezulu, njengobhedu, zikholisa ukuvelisa ubushushu obuninzi.
4. Isixhobo soMsebenzi: Ukuchasana kombane kwezinto zokusebenza kudlala indima ebalulekileyo ekuveliseni ukushisa. Izixhobo ezinokuxhathisa okuphezulu, njengentsimbi engatyiwa, zivelisa ubushushu obuninzi kunezinto ezinokumelana okuphantsi, njenge-aluminiyam.
5. Ixesha le-Welding: Amaxesha amade e-welding anokukhokelela ekwandeni kokuveliswa kobushushu njengoko ubushushu bunexesha elininzi lokuqokelela kwi-weld interface.
6. Electrode Ingcebiso yeJiyometri: Ubume kunye nemeko yeengcebiso ze-electrode zichaphazela ukuchasana noqhagamshelwano, nto leyo echaphazela ukuveliswa kobushushu.

Kwindawo yokumelana ne-welding, ukuqonda iindlela zokuvelisa ubushushu kunye nezinto eziphembelelayo kubalulekile ekufezekiseni i-welds ezikumgangatho ophezulu. Ngokulawula ngokucophelela iiparitha ezifana ne-welding current, amandla e-electrode, kunye nokukhethwa kwezinto eziphathekayo, abavelisi banokwandisa inkqubo ye-welding ukuvelisa amajoyina anamandla kunye athembekileyo ngelixa benciphisa amandla okuba neziphene ezibangelwa ukushisa okukhulu. Olu lwazi lunegalelo kubuchule obupheleleyo kunye nokusebenza kweendawo zokumelana ne-welding kwizicelo ezahlukeneyo zamashishini.
