I-Spot welding luhlobo lwe-welding ye-press kunye nefom yendabukoukumelana welding. Iyinxalenye ebalulekileyo yesinyithi kwaye isetyenziswa kumashishini amaninzi. Eli nqaku liza kuchaza imigaqo kunye neendlela zokusebenza ze-welding yendawo ngokweenkcukacha ukukunceda uqonde ngcono ukuba yeyiphi i-spot welding.

 Yintoni iSpot Welding?

I-Spot welding yindlela yokudibanisa isinyithi apho uxinzelelo lusetyenziswa kwi-workpieces zetsimbi ngama-electrode aphezulu nangaphantsi, kwaye umsinga wombane uyazifudumeza ngexesha elimiselweyo, okwenza ukuba isinyithi sidibanise kwiindawo zoqhagamshelwano. Ii-electrodes zenziwa ngobhedu ngenxa ye-conductivity ephezulu ye-thermal kunye nokumelana okuphantsi. Xa i-current idlula i-electrodes kunye ne-workpieces yensimbi, ubushushu bugxininiswe kwiindawo zoqhagamshelwano, bunyibilike kwi-plastic state. Umsinga uyayekwa, kodwa uxinzelelo lugcinwa, ludibanisa iindawo zoqhagamshelwano kunye. I-spot welds incinci ngokwentelekiso, kunye nedayamitha yendawo ye-weld nganye ukusuka malunga ne-3 ukuya kwi-20 mm.

Isebenza njani iSpot Welding?

Sahlula inkqubo ye-welding yendawo ibe ngamanyathelo amane: ukubeka iiparitha, ukubeka izixhobo zokusebenza, ukufaka uxinzelelo, kunye nokudlula okwangoku.

Ukumisela iiParameters

Inyathelo elibalulekileyo kwi-welding yendawo kukuseta iiparamitha ze-welding. Ubushushu obuveliswayo ngexesha le-welding imiselwa ikakhulu ziiparamitha ezintathu: zangoku, ukuxhathisa, kunye nexesha. Ubudlelwane phakathi kwezi parameters bubonakaliswa ngolu nxaki lulandelayo:

Q = I²Rt

Q = ubushushu obuveliswayo

I = welding current

R = ukuchasana kwi-electrode

T = ubude bexesha lokuhamba kwangoku

Ezi parameters zichaphazela omnye nomnye kwaye zinqume umgangatho we-welding. Umsinga unempembelelo enkulu; ixabiso layo eliphindwe kabini kwi-equation lichaphazela kakhulu ubushushu obuveliswayo. Ngoko ke, ukulawula umsinga kubalulekile. Ukuba i-welding current iphezulu kakhulu, inokubangela i-deformation kunye ne-bubbles kwi-weld. Ukuba umsinga uphantsi kakhulu, izixhobo zokusebenza aziyi kunyibilika kakuhle.

Ukuxhathisa kwi-electrode kulucelomngeni ukulungelelanisa ngexesha le-welding, njengoko kuxhomekeke ngokukodwa kwimilo ye-electrode kunye nobukhulu. Ubude bexesha lokuhamba kwangoku lubalulekile kwaye kufuneka lubekwe ngokuhambelana nezinye iiparamitha ukufezekisa iziphumo ezifunwayo. Ukongeza, uxinzelelo lwe-welding yenye into ephambili. Ngaphandle koxinzelelo olwaneleyo, ukuwelda indawo eyimpumelelo kunzima ukufezekisa.

Ukulungelelaniswa kweMetal

Emva kokulungelelanisa iiparamitha, iinkqubo weldingiqala. Okokuqala, beka ii-workpieces phakathi kwee-electrode ezimbini, ukulungelelanisa isinyithi ukuze i-electrodes ijolise kwindawo ekudityaniswa kuyo. Eli nyathelo libalulekile kuba ukuba indawo ye-welding ayilungelelaniswanga, i-weld iya kucima, mhlawumbi ibangele ukuba imveliso ibe nesiphene. Xa iziqwenga zetsimbi zinemilo ekhethekileyo okanye zifuna ukuchaneka okuphezulu, kunokuba ngumngeni ukulungelelanisa indawo ye-weld ngokubonakalayo. Kwiimeko ezinjalo, kuyimfuneko ukudala i-jig ekhethekileyo. Ngale ndlela, kufuneka ubeke kuphela iziqwenga zetsimbi kwi-jig ukuqinisekisa ukulungelelaniswa okufanelekileyo kwe-welding.

Faka Uxinzelelo

Isinyathelo sesithathu kwi-welding kukusebenzisa uxinzelelo kwizinto zokusebenza zetsimbi. I-electrodes ihambela kwizinto zokusebenza zetsimbi kwaye ifake uxinzelelo, iqinisekisa ukuba i-workpieces kunye ne-electrodes zidibanisa ngokuqinileyo.

Ukudlula Ngoku

Emva kokuba i-electrodes igxininiswe ngokupheleleyo kwintsimbi, ungaqala okwangoku. Ngeli xesha, i-current iphuma kwi-electrodes ukuya kwizinto zokusebenza zetsimbi, ezibangela ukuba isinyithi sinyibilike. Xa ixesha elimisiweyo langoku liphela, umsinga uyayeka ngokuzenzekelayo. Ngeli xesha, i-electrodes iyaqhubeka nokusebenzisa uxinzelelo, ivumela ukuba isinyithi esivuthayo sidibanise kunye. Ekugqibeleni, i-electrodes ikhutshwa, igqibezela i-weld.

Izinto eziqhelekileyo ezifanelekileyo kwi-Spot Welding

Intsimbi yekhabhoni ephantsiisetyenziswa kakhulu kwiindawo zeemoto kunye nentsimbi yentsimbi. Ngolu hlobo lwezinto eziphathekayo, unokuseta i-current ephezulu kunye nexesha elifutshane le-welding ukunceda ukwenza amabala e-weld aqinileyo.

Aluminiyaminokutshatyalaliswa kobushushu obuhle kunye ne-conductivity, kunye nokuchasana okuphantsi kakhulu. Nangona kunjalo, umphezulu wayo udibanisa ngokulula. Xa udibanisa amaphepha e-aluminiyam, khetha izixhobo ze-welding eziphezulu kwaye usebenzise okwangoku okuphantsi kunye nokusetha ixesha elide le-welding.

Yenziwe ngentsimbi eshayinayoi-welding, i-pulse welding idla ngokusetyenziselwa ukunciphisa impembelelo yendawo echatshazelwe bubushushu kwimbonakalo, ukuqinisekisa ukuba i-weld ihlangabezana neemfuno zobuhle.

Xa i-welding sheets, i-zinc layer phezu komhlaba inendawo ephantsi yokunyibilika, efikeleleka ngokulula, ibangela i-splatter ebalulekileyo kunye nokunamathela kwe-electrode, okukhokelela kwi-welding engazinzanga yangoku. Sisebenzisa inkqubo yangoku ye-welding yamanyathelo amabini: inyathelo lokuqala lisebenzisa i-current encinci ukutyhutyha i-zinc layer, kwaye inyathelo lesibini lilungisa langoku kwiiparamitha ezifanelekileyo ze-welding ukunciphisa i-splatter kunye ne-electrode sticking, ukuphucula ukuzinza kwe-welding.

Ukongeza kwezi, iingcingo zobhedu kunye neepleyiti, intsimbi ephezulu, intsimbi, kunye nezinye iintsimbi nazo zinokudityaniswa kusetyenziswa iindlela zokuwelding. Izinto ezahlukeneyo zinokufuna iiparamitha ze-welding ezahlukeneyo.

Usetyenziso lweSpot Welding

I-Spot welding isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo ezifana neemoto, i-electronics, izixhobo zasekhaya, kunye namashishini esinyithi. Kushishino lweemoto, ukuwelda kusetyenziselwa ukuhlanganisa umzimba wemoto, onokwakheka okuntsokothileyo, okuhlala kusetyenziswa iiwelder eziphathwayo okanye iinkqubo zokuwelda indawo ezizenzekelayo. Iindawo ezininzi zentsimbi ezimotweni, njengeepaneli ezisecaleni, i-absorber, kunye neebrake pads, nazo zifuna ukuwelda. I-Spot welding ifanelekile ngokubanzi kwimveliso yenxalenye yentsimbi ephezulu. Ukuba ufuna ukuwelda amashiti esinyithi angama-20,000 ngenyanga, ukuwelda yeyona nto ilungileyo.

5. Akukho NONENgokungafaniyo nezinye iindlela zokuwelda ezifuna imathiriyeli yokuzalisa rhoqo, ukuwelda kwebala kudibanisa ngokuthe ngqo izinto ezimbini zokusebenza kunye ngaphandle kwesidingo semathiriyeli eyongezelelweyo.

Ezi nzuzo zenza i-welding yendawo ibe yinto ekhethwayo kumashishini afuna ukusebenza kakuhle, ubuhle, ukhuseleko, i-automated, kunye neenkqubo zokujoyina isinyithi esebenzayo.

Unyino lweendawo ezixhathisayo welding

Ngelixa i-welding yendawo inamandla, ukusetyenziswa kwayo kulinganiselwe ngenxa yemiqobo ethile yolwakhiwo:

1. Ukuchaneka kwi-Positioning: I-Spot welding igqiba ngokukhutshwa okukodwa. Ngaphandle kweenkqubo ezichanekileyo zokubeka, ukungahambi kakuhle kunokukhokelela kwiziphene zemveliso kunye ne-scrap.

2. Ukutyeba kunye nezithintelo zeMilo: I-Spot welding ifanelekile ngokubanzi ukuwelda amashiti amancinci (0-6mm). Iimathiriyeli ezishinyeneyo okanye ezimile ngendlela eyodwa zingumceli mngeni ukuwelda kusetyenziswa ukuwelda, nto leyo ebangela ukuba kusetyenziswe obunye ubugcisa bokuwelda kwiipleyiti ezishinyeneyo okanye imibhobho.

3. Amandla adibeneyo: Amalungu adityanisiweyo kwi-welding yendawo angeke abe namandla ngenxa yokuba yinkqubo ye-welding yendawo, egxininisa kwi-welding enye indawo ngexesha.

4. Imingeni yoLawulo loMgangatho: I-Spot welding ibandakanya iiparitha ezininzi, nganye ichaphazela umgangatho we-welding. Ukulungiswa okungafanelekanga kweeparamitha, ezifana noxinzelelo, kunokubangela iziphumo ze-welding ezingafezekanga.

Le mida ifuna ukuba kuqwalaselwe ngononophelo uhlobo lwemathiriyeli, ubukhulu, kunye neemfuno ze-welding xa ukhetha ukuwelda indawo okanye ezinye iindlela kwiimfuno ezahlukeneyo zokwenziwa.

Umatshini we-Spot Welding

Ukuze ugqibezele imisebenzi ye-welding, udinga aumatshini wokuwelda indawo. Oomatshini be-spot welding ngokubanzi beza kwiindlela ezininzi:Izitshizi zeendawo ezimileyo, iiwelder zebenchtop,indawo yokudibanisa umpu ophathwayo, kwayeiindawo ezininzi zokuwelda. Ukukhetha umatshini wokuwelda indawo kuxhomekeke kakhulu kwimilo kunye nobukhulu bezinto zakho zentsimbi. Kumaphepha alula angama-2 mm ubukhulu, i-welder yendawo ethe nkqo yanele. Nangona kunjalo, kwimizimba yemoto ye-welding apho i-workpieces kunzima ukuyihambisa, i-welding tongs ephathekayo iyasetyenziswa. Ukuba kufuneka udibanise amabala amaninzi kwizinto zetsimbi ngexesha elinye, i-welder eneendawo ezininzi ifanelekile.
