Welding of ucingo lobhedu: a ngokutsha iindlela nezixhobo. Ngelotha okanye welding of iingcingo zekopolo - kokona kulungileyo?

Umsebenzi ophambili xa uqhagamshela naziphi na uqhagamshelwano lombane kukuqinisekisa besenza ubuncinane. Xa ukumelana contact ihlwempu phakathi iingcingo zekopolo kakuhle kakhulu, nto leyo intambo ukufudumeza. Zininzi iindlela ukuqhagamshelana unxibelelwano, kodwa inokuthenjwa nolusebenzayo kucingwa ukuba welding ucingo lobhedu. Le iteknoloji ikuvumela monolithically ukudibanisa yonke imisonto ngocingo, ngokwenjenjalo ekufezekiseni ukuxhathisa iphantsi kunokwenzeka zombane. Ngenxa yale iingcingo zobushushu iyapheliswa, oko yandiswe ngokubonakalayo inqanaba ukhuseleko emlilweni.

Iindlela ezintambo uqhagamshelo

Ubhedu umbandela main umqhubi. ngenxa iipropati physico-eekhemikhali lo mbandela (ductility eliphezulu, ukungabikho luthambe) Hi, esebenza nabo uneempawu zawo. imithetho isixhobo sombane bathi imisebenzi kwisebe uqhagamshelwano ngemithambo okontsovyvaniyu kweentambo kunye iingcingo ingaqhutywa ngelotha, welding, crimping okanye ukucudisa (lizulu, ujije, njalo njalo). Ngamnye kubo uneempawu zawo, nto leyo eza kuxoxwa ngezantsi.

iingcingo ambaxa ngokuthi stranding

A twist olula iingcingo engaqondanga PUE, njengoko yeyona kakuhle, uqhagamshelo mifutshane, nomlilo. Ngaphandle koku, neengcibi basekhaya ndingayeki ukusebenzisa le ndlela, nangona imiphumo le "wobugcisa" kunokuba plavchevnymi kakhulu.

Linegunya iingcingo uye ethile enkulu: uqhagamshelo zobhedu ekugqibeleni gqitha yaye buthathaka, ekugqibeleni zitshatyalaliswe ngokupheleleyo ngenxa uxhathiso eliphezulu inguqu.

Kufuneka kukhunjulwe ukuba indlela linegunya nga tirhisiwaka kuphela kwiimeko ezizodwa, ukuba kukho imfuno engxamisekileyo ukubuyisela umbane kunye nezinye iindlela kwimeko ethile azifumaneki. Kubaluleke kakhulu ukuba ukuthatha unonophelo malunga umgangatho, ukhuseleko nokuthembeka zo xhulumaniso.

Akuvunyelwe ngokungqongqo:

• Idibanisa iingcingo wabumba ngezinto ezahlukeneyo (aluminiyamu nangobhedu);
• Ukunxulumanisa ucingo lobhedu esiluqilima nge multifilamentary.

inkqubo Stranding imi ngolu hlobo lulandelayo:

1. Ecacileyo wire yokwambathisa ukusuka kumgama 6-8 cm ukusuka kolunye udini lwalo;
2. Faka ucingo omnye komnye yaye crosswise qhina kakhulu ashinyeneyo. Ukuba icandelo umnqamlezo kwicingo yobhedu ngaphezulu kwe-1 macala onke. mm, umsebenzi lwenziwa kunye ga kulo.
3. Nomntana iincam forceps eseleyo macingo.
4. Linegunya zigqunyiwe ngokusebenzisa izixhobo ezikhethekileyo ubushushu (PVC, okanye iityhubhu ubushushu sofinyela, iminqwazi) okanye kwiiseli ezininzi zokwambathisa tape. Zokuvala kufuneka nakanjani mazifake iingcingo ubushushu umaleko.

kovavanyo loxinzelelo

Le nkqubo yinkqubo iingcingo ngenxa okukhethekile crimping kwisingxobo tubular okanye icebiso. zisetyenziswa ezi zixhobo, ukuba icandelo umnqamlezo kwicingo ubhedu 2,5-240 macala onke. mm. iingenelo echaza iteknoloji crimp ezi isantya nokuchaneka umsebenzi, kwakunye iyahlala nokhuseleko uxhulumaniso ezilandelayo.

Kuba crimping usebenzisa isixhobo ezikhethekileyo - iplayasi ngomatshini, hydraulic okanye zombane okanye cinezela obzhimochnye umsebenzi. Ukukhethwa casings kuya kususela kwinani amacandelo kunye enxulumene yi iingcingo.

Emva bamhluba nokucocwa zokuphila, ukuba siwasebenzisa zwi-vaseline paste, anxibe umkhono bavelise crimp. enemikhono ucinezelo ekude.

Crimping ezinjengeetheminali

Ukusetyenziswa ezahlukeneyo crimps ezinjengeetheminali kwaye yonke ngokudibanisa iintambo zombane, itshintshela, zalapho ukukhanya, kwakunye ufakelo switchboards. Ezi zixhobo ukuvumela ubhedu Qhagamshela wire eqinileyo echanileyo nekhawulezayo, wire ndixakene kodwa ngaphandle pre-welds okanye crimp ityhubhu kwincam kwi-terminal Screw uqinisa akunakwenzeka.

Izinto eziluncedo echaza iiterminal Screw inokuquka uqhagamshelwano aluminiyam kweentambo ngobhedu, kwaye akukho mfuneko yokuba lilolo elandelayo labantu ofowunelana nabo.

Nangona kunjalo, olu hlobo lonxibelelwano ayikho ngaphandle iziphako. Kufuneka isondlo ngamaxesha athile, ekukho phakathi Ukucofa izinto nokubotshwa. Ubhedu - impahla ethambileyo kakhulu, sinotyekelo "ukuvuza" phantsi umthwalo. Ukuba nokuba wenze unxibelelwano ngokusebenzisa emibonweni kwentwasahlobo-lolayisho ezinjengeetheminali cleat, ngenxa encinane kakhulu imiphezulu indawo zoqhagamshelwano kwi nomthwalo onzima itshiswa kwaye kukhupha izinto yasentwasahlobo, apho kwimo yazo kunciphisa kunye nomgangatho compound.

Pike VS-welding

Ukuqinisekisa uqhagamshelwano entle ezininzi eziqhele ukusetyenziswa ngelotha okanye welding of iingcingo zekopolo. Ukuba siya kuba ezi ndlela? Ngokuqinisekileyo, welding. Isibakala sokuba ngelotha - Inkqubo nzima kakhulu kwaye ixesha elide, ingakumbi xa ufuna ukudibanisa balahleke cable zezobhedu. Plus, imichiza commissural ekugqibeleni batshatyalaliswe ngenxa yobukho intsimbi yesithathu, friable ngakumbi yaye ngokulula fusible - solder. Ubukho yenkcaso utshintsho kwamalunga aluminiyamu ezahlukeneyo kunegalelo inkangeleko reactions chemical etshabalalisayo kunye nezinye iinkqubo ezingafanelekanga.

Xa welding lwenziwa ucingo lobhedu, igama elithi "zoqhagamshelwano" liyalahleka jikelele ngenxa yokuba ezimbaxa monolithic lufumaneka uhlobo olufanayo ngentsimbi. Ngokuqhelekileyo, ezi zinto zahluka irekhodi ukumelana ephantsi, apho ubushushu ngenkankulu kukhululwa.

ngelotha

Ngoko nangoko ke kufanele kuphawulwe ukuba lo msebenzi ufuna umlinganiselo othile ulwazi kunye namava. Ngumzali, kodwa phawu aluka ngcono ngelotha amahlwempu, khumbula oku.

inkqubo ngelotha iqala nge pre-unyango lwe iziphelo macingo yokwambathisa oxides. Emva kokuba iyaqaliswa, isale into ezikhethekileyo - ekubhobhozeni ke hocus. Solder copper ayikwazi kuphela, kodwa i-aluminiyam, into engundoqo ezi ngcingo - ukukhetha wobhobhozayo ekunene kwaye solder. Ukusebenzisa acid ekubhobhozeni esebenzayo akunconywa, njengoko kufuneka ukuba ahlale phezu oogesi, kangangokuba umchiza ichithwe ngokukhawuleza.

Enye ngelotha kuthatha ixesha elide, kodwa ukuba kwenziwa ngokuchanekileyo, uxhulumaniso uya kuba ethembekileyo ixesha elide. Yakuba iingcingo lwehle, kufuneka ngerabha ngenyameko.

welding

Eyona ezikumgangatho ophezulu kunye uqhagamshelo olukhuselekileyo yakha ucingo iwelding yobhedu. Le uxhathiso kwi kwicingo zoqhagamshelwano ayidluli umlinganiselo esemgangathweni besenza. Lendlela akafuni kufuna ixesha elininzi kwaye kuthathwa elula kakhulu. Xa phambi eliphantsi lobuchule nolwazi iwelding of iingcingo zekopolo ekhaya doable.

Xa ekwenzeni umsebenzi welding yonke imithetho zomlilo kunye nokhuseleko zombane mawulandelwe ngokuthe ngqo. Ukuthintela ukutsha kunye nokwenzakala amehlo kufuneka asebenzise izixhobo zakho protective - iimpahla zokuzikhusela neeglavu, welding ntloko okanye izibuko.

izixhobo welding

iingcingo Compound yi welding wenza kwezixhobo kweentlobo ezahlukeneyo. Kuyinto elula kakhulu ukuba ukusebenzisa i izixhobo inverter ngenxa ukuwelda iingcingo zekopolo, ekubeni olu hlobo kwezixhobo luphawulwa ubungakanani amancinci kunye ubunzima, power enoqoqosho kunye noluhlu olubanzi ukuwelda izicwangciso zangoku. Ezi iingenelo ukukwazi ukunika ukutshisa oluqhubekayo arc yombane.

Ukuba izicwangciso isixa esikhulu umbane, ekufunyanweni inverter kumatshini welding efanelekileyo ngokupheleleyo yaye kufanelekile. Ukongeza, le nezezixhobo ngokuqinisekileyo kuxoka "ubunzima abafileyo" kwixesha elizayo.

Iimpawu ze inqubo ngcingo welding ukusuka ngobhedu

Segesi ucingo lobhedu kunokuba zombini AC and DC ombane ngamaxabiso ka 15-30 C. Kulungile ukuba icebo inika ithuba ukunyenyisa yangoku.

Umzekelo, ukuba weld izinikezeli ezimbini zobhedu 1.5 macala onke. mm, kwanele 70 A. Kuba welding le micwe yocingo emithathu icandelo efanayo emnqamlezweni kuyimfuneko ukwandisa zangoku 90 A. Compound abaqhubi ezintathu 2.5kb. mm uya kufuna ukusuka 80 ukuya 100 A, ucingo welding ezintlanu efanayo - 120 A. Ukuba ekhethiweyo iwelding elilelona yangoku lungenzeki "enamathele" i electrode kunye arc uzinzile ngokwaneleyo.
Kuba welding of iingcingo zekopolo kusetyenziswa carbon-copper "iipensile" (electrode). Ukuba akunjalo, unako ukusebenzisa iintonga carbon evela iibhetri ipensile.

izenzo welding

Iincam ubude Ukubiyelwa 5-6 cm kwaye lingadlulanga i ukutyabeka ubushushu kwaye ecikizekileyo ukususela amacandelo yokugquma, ukushiya 5-6 mm ekupheleni ukujijwa ifomu untwisted. Ezi ngcebiso kufuneka isasazwe, agobe ngaxeshanye kunye kufutshane omnye komnye. Zijije iingcingo ezintathu okanye ngaphezulu, ekupheleni usafuna kufuneka ukuba ushiye ezimbini kuphela tip ezamahala, kwaye abanye ndinqumle kwindawo kumjikelo wokugqibela yabakholwayo. Ukuba umatshini ayikho lunamandla ngokwaneleyo, le jija kuya kuvumela lula ngakumbi ibe bead anyibilike. Ukuba kukho ngoku obaneleyo izixhobo iwelding enze twist elula.

linegunya Further ska nge nokubotshwa welding. Ukuba le divaysi ongekhoyo, ungasebenzisa iplayasi kwendala engenanto.

Umchiza walungisa iye welding carbon electrode. Ngexesha welding, le iingcingo zekopolo baya kwenjenjalo ukunyibilikiswa ngasekhohlo iziphelo untwisted phambi yokuseka ibhola otyhidiweyo. Ukuqinisekisa i mechanical kunye lombane wire zoqhagamshelwano oluthembekileyo, ummandla ukunyibilika kufuneka uqiniseke ukuya stranding.

Ubude welding kufuneka mayingagqithi imizuzwana 2-3, kungenjalo ucingo usambathisa weld. Emva Ukupholisa epheleleyo compound wavelisa kude kwaso usebenzisa ezahlukahukeneyo lwe tape okanye ikepusi ezizodwa, PVC, okanye ubushushu Shwabanisa zokutyubhisha.
