Izixhobo indawo welding ngezandla zabo

Isixhobo ngokuba indawo welding sisixhobo sele kwiinkqubo ezininzi, ngokubonelela iinxalenye uxhulumaniso ethembekileyo. Umgangatho umphumo iphenjelelwa yimiba ezifana isixa lwangoku, uhlobo ezimbaxa eziphathekayo kunye nemilinganiselo ummandla i electrode.

incazelo

Spot welding kusetyenziswa zombini kwiimeko mveliso kunye nendlu. It elungiselelwe ukusebenza kunye profiles egosogoso, iimveliso insimbi nonferrous. Le ndlela inika komphetho amandla ephakamileyo kunye noqoqosho. Ukongeza, ungasebenzisa kwi lokulungiswa kwezixhobo zasekhitshini kunye nezixhobo ezahlukeneyo.

Le nkqubo isekelwe phezu indibanisela lweziqalelo ngamnye entengo yazo. Emva koko usebenzisa i zokufudumeza zombane yangoku iinxalenye zaveliswa. ingqalelo ekhethekileyo ihlawulwa lungiselelo isalamane izakhi kwinqanaba elifunekayo, apho igcinwa kulo lonke ukuhamba. Iinkcukacha abe mnye ngenxa ngokunyityilikiswa umbandela avela phantsi kwempembelelo ubume thermal.

iintlobo

izixhobo Mechanical ngokuba indawo welding manual kwaye ifuna lofakelo ixabiso phambi kokuyisebenzisa. Uncedo engundoqo ulwakhiwo ilula kwaye ukukwazi ukuvelisa ekhaya. Baye ithole lusetyenziswa kakhulu kwaye ziye zasetyenziswa mveliso ezininzi.

izixhobo Zenzekelayo ukuvumela ukuba bafumane iikhompawundi ubuncinane inani umtshato. Ngelo xesha, weza engasebenziyo kufuna izakhono ezizodwa, kunye neendleko izisebenzi ziyancipha.

Ishishini aza kusetyenziswa izixhobo anomoya kunye hydraulic.

I-inventri Iindleko eliphezulu izixhobo ezahlukeneyo ndawo welding, kodwa sele zande ngenxa ithuba ukudibanisa kwi Inetweki yekhaya, uluhlu lwemisebenzi kunye nobukhulu compact.

Ngaphandle kwento yokuba iiyunithi ezithwalwayo thile elingezantsi ezisisigxina, zinikeza umthungo ophezulu ezikumgangatho ngeendleko iphantsi sezixhobo. Ngoko ke kunokwenzeka ukuba ukusebenza kunye metal ukuya ku 6-7 mm ububanzi.

The main izinto

Welding Umatshini ibala iwelding kunokwenziwa ekhaya. Zizixhobo kakhulu ethandwa ezifunyenwe ixabiso ezingalawulwayo yangoku. Loo izixhobo ilawulwa ngenxa ubume zombane, ixesha apho yahluka na utshintsho okanye irileyi.

Enye yezinto eziphambili i sombane obonelela oluyimfuneko kwinqanaba yangoku. Ukulungiselela le njongo umntu ukusebenzisa le lale ukusuka oven, leyo uneempawu efanelekileyo kunye nokufikeleleka ezahlukeneyo. Loo okuzithandelayo izixhobo indawo welding ilungele ukuba ukusebenza kunye izahlulo metal kwi 1-2 mm ububanzi. Xa amathuba ngempumelelo enkulu kukuba ukhethe ukusuka enamandla oveni transformers microwave. Kufuneka kuqatshelwe ukuba kwizixhobo kwabendlu uhlobo magnetron ezisebenza kwi ombane ka-4000 V. Ngoko ke, imicwe sombane abe ubukhulu enkulu, kwaye inani amathuba kwi yesibini siya kuba ngaphantsi kakhulu kunalowo primary.

oyinkampani

le yesibini kwayijikeleza wire le transformer zisuswe kunye hacksaw okanye basike, kwezinye iimeko kuyimfuneko bangabheneli kusombiwa. Akucetyiswa ayibhutyuze ukusongwa, ukuze umonakalo iintambo. Phambi shunts baya nayo kufuneka isuswe, njengoko igalelo kumda yangoku.

zamabanga New siya kwenziwa emva kokususa kwiindawo eziyimfuneko. Esebenzisa intambo sobhedu kunye necandelo umnqamlezo mm² hayi ngaphantsi kwe-100 onokufikelela uxinezeleko lusebenze. Kwezinye iimeko ukususwa ekwambathiseni lwangaphandle, nto leyo akavumeli efana jiko. Oku kungenziwa indawo tape ngelaphu ubushushu, iintambo isetyenziswe ubude ezincinane ukunciphisa ukuxhathisa.

Ngokuba ukusetyenziswa ekhaya, ngokuqhelekileyo ezintathu kuphela amathuba, kunye imilinganiselo ifowuni kwandisa ixabiso yangoku. Kwakhona, amandla ezongezelelweyo kunokuzuzwa ngokufakelwa abaguquli eziliqela.

Oko Ufanele Ukwazi

Izixhobo spot welding, izandla zabo microwave ndawonye, ifuna ukusetyenziswa electrode kwi kwiisekethe ezizisekondari. Kwimeko ye abaguquli ezimbini amandla enye kufuneka ukudibanisa neengcingo kwi mm 10 shinyi, Iziphelo abaqhagamshelwe electrode. Kufuneka ilunyukelwe kakhulu xa odibanisa engathi zaseprayimari nezasesekondari ukunqanda mfutshane-kombane.

Ngokobukhulu window zaneleyo le magnetron, leyo nzima Akubuya intambo ukudibanisa, kunye nokusetyenziswa ngaxeshanye abaguquli amandla eliphezulu, kucetyiswa uqhagamshelo uthotho lwe engathi ezizisekondari. oyinkampani ulwalathiso kufuneka ezihambelanayo,-non ukungathotyelwa kwalo mgaqo na amathuba eliphezulu antiphase kwaye, ngenxa yoko, le ombane zero kwimveliso.

ombane

Abaguquli enegama elifanayo kwi izigqibo kuboniswa ngolu phawu okanye ileta. Xa kungekho nayiphi na iziphawuli kucetyiswa ukuba usebenzise voltmeter ukuvavanya. Kuyimfuneko ukuba isicelo ombane ukuya primary jiko ngokudibanisa isixhobo secondary. Kwimeko ngokubhijela ezinjengeetheminali uqhagamshelo voltmeter oppositely ubonisa ombane. Oku kungenxa yokuba i-primary jiko inika ombane lesibini, endalumkayo kuyo aguqulwa kabini.

Xa uqhagamshele izibini engathi eponymous ombane imveliso kwi yesibini kwayijikeleza ziya kuba malunga kunye voltmeter iya kubonisa ixabiso zero.

Ukuze wenze ukuba isixhobo enamandla ngakumbi ndawo welding, kunokwenzeka ukuba ukusebenzisa abaguquli ezininzi, ngoko kuyimfuneko ukuze bakuthathele ingqalelo intsebenzo yenethiwekhi. Ezi zixhobo ombane iyonke kufuneka libe ngaphezulu ngexabiso elimisiweyo. Eyona ndlela ilungileyo ibiya kuba amandla zangoku kwi kuluhlu 1000-2000 A.

electrode

Electrode elihlolwa ngcono akhutshwa imivalo ubhedu ukuba ubukhulu ngokwaneleyo, loo ubukhulu kufuneka ilingane yoMgaqo-wire. Ekuhambeni kwexesha, i electrode ukutshintsha imilo yabo ayikufanelanga ukuba umsebenzi, ngoko ke kufuneka ukumpompa rhoqo. Kuyanconywa ukunciphisa inani unxulumano kunye nobude cable osusela nesiguquli ukuya electrode, ukuze kwandiswe amandla. Eyona ndlela ilungileyo ibiya kuba ukudibanisa i electrode ukuya lugs ezenziwe ngobhedu, wayifaka ukuya esiphelweni macingo. Ukuthintela igcwala ngobhedu lomfowunelwa amanqaku kufuneka weld iindawo, kwaye oko kuya kwenza kube lula zokuhlanjululwa ngakumbi. Kubalulekile ukuphawula ukuba ukuze kuncitshiswe ilahleko, ungasebenzisa crimp.

ulawulo

Spot izixhobo welding for neebhetri basoloko mayixhotyiswe kwesibambi esijijwayo, ukunika amandla ezongezelelweyo ngexesha lokusebenza. ulawulo Device lwenziwa yi lempumelelo okanye iswitshi. Okubaluleke kakhulu ke qualitative nomphetho electrode kuyimfuneko eqhelekileyo yokusebenza. Xa izixhobo iya kuba ngakumbi bekhululekile, kunye obandayo zokubhala kunye nobunzima eyaneleyo. Iswitshi kufuneka ibe ethembekileyo elide.

Udibaniso lwe iswitshi iqhosha senziwa kuphela samabanga jiko, kulo mzekelo kuhlala abafowunelwa ingqibelelo kunye nokumelana ezongezelelweyo ziya kuthintelwa.

Izixhobo kunye uneswitshi lever efakwe kwi NIP siseko yolawulo ngaloo ndlela kube lula ukulawula kunye nenkqubo iwelding ngesandla esinye.

Zicinywa ziphinde zikhanyiswe koomatshini manual iwelding ndawo kuphela xa i electrode ukwazi. Kuyanconywa ukuba ufake umoya unyanzelekile, nto leyo evumela ukuba asebenze ngaphandle breaks rhoqo esweni umgangatho ababhexeshi zokufudumeza electrode.

Ukulungiswa uxhulumaniso ekhuselekileyo kunokwenzeka kuphela xa ulwazi zonke ubuqili zenkqubo, ingakumbi, kufuneka akwazi ukubona amanqanaba yokulungela ngeempawu zangaphandle kunye nezinto umthunzi uno lwazi nge ubume yangoku. ezihambayo electrode rate kufuneka zibe kumgangatho ofanayo ngexesha lenkqubo iwelding yonke.

ukuphepha

Of kubaluleke kakhulu ukuba kugcinwe imigangatho yokhuseleko xa usebenza njengesixhobo ezinesiphosiso ndawo iwelding kunokubangela lobuqu ukwenzakala okanye umonakalo workpieces. Kwakhona, kufuneka bathobele ezi mfuno zilandelayo:

• ukusetyenziswa imaski ekhethekileyo ukukhusela ubuso bakho kunye amehlo afefe iintlantsi;
• yokwambathisa electric neentambo kokuxhuma;
• akukho izinto ezinokutsha okanye ulwelo kufuphi nesiza of iwelding;
• ukusetyenziswa mittens neeglavu zokuzikhusela ngokuchasene ukutsha;
• umoya rhoqo kwelo gumbi, ukubonelela umoya ucoco iigesi eziyingozi;
• ikhona indlela yokuba ucimayo umlilo;
• ukhuseleko imiphezulu ngomthi (umgangatho, itheyibhile) of iintlantsi.

inkqubo Iimpawu

Musa ukulibala malunga wokulungiselela umsebenzi eziyimfuneko ukufumana umgangatho weld. ngaphambili izinto eziluncedo acoca uthuli ubumdaka kunye iibhrashi kunye nemixube ezizodwa. Spot welding bomashini welding ngezandla zakhe ngamaxesha uquka amanyathelo ezimbalwa ezingundoqo, ebandakanya oku kulandelayo:

• izinto placement ukuqhagamshela kwindawo efunekayo;
• ngokucinezela iindawo phakathi electrode;
• ukufudumeza de plasticity evumayo ukuba ukugqabhuza le metal.

Kubalulekile ukuphawula ukuba ngoxa kwinqanaba yokunqongophala elalana Inokwenzeka, evela yokusilela engundoqo cast of ubukhulu ayo. Tracking isiphako kunzima, ngexesha elifanayo oko kunokukhokelela neziphumo ezilandelayo:

• ukuyilwa ndi kunye amaqokobhe;
• zavuleka, iindawo zale Elements;
• abase-ngokusebenzisa izinto
• Isakhiwo misindo of umphakathi welding.
