1. Muchidimbu
Roll welding imhando ye resistance welding. Iyo inzira yekushongedza iyo iyo workpieces inounganidzwa kuti iite lap joint kana butt joint, yozoiswa pakati pemaroller electrode maviri. Iwo ma electrode anotenderedza anodzvanya weldment uye kutenderera, uye simba rinoramba richiiswa kana kupindirana kuti riite inoenderera weld. Roll welding inoshandiswa zvakanyanya mukugadzira majoini anoda kuiswa chisimbiso, uye dzimwe nguva inoshandiswa kubatanidza nhengo dzisina kuvharwa pepa resimbi. Ukobvu hwesimbi yakasungwa simbi inowanzoita 0.1-2.5 mm.
Mabhero anoshandiswa mumavharuvhu, kunyanya kuvhara nekuzviparadzanisa nevamwe. Mumavharuvhu akasiyana-siyana, ingave vharuvhu yekumisa, throttle valve, inodzora vharafu kana yekumanikidza kuderedza vharafu, mabhero anoshandiswa seyekurongedza-isina chisimbiso chekuzviparadzanisa chechikamu chehunde yevharuvhu. Panguva yekushanda kwevharuvhu, mabhero uye tsinde yevharuvhu zvinobviswa axially uye zvinogadziriswa pamwechete. Panguva imwecheteyo, inomirawo nekumanikidzwa kwemvura uye inovimbisa kuiswa chisimbiso. Kuenzaniswa nemavharuvhu ekurongedza, mavharuvhu ane kuvimbika kwakanyanya uye hupenyu hwebasa. Naizvozvo, mabhero mavharuvhu ave achishandiswa zvakanyanya muminda yenyukireya, peturu, indasitiri yemakemikari, mushonga, aerospace, nezvimwewo. Mukushandisa zvinoshanda, mabhero anowanzo batanidzwa pamwe nezvimwe zvinhu zvakaita semaflange, pombi uye mavharuvhu madzinde. Iwo mabhero akaiswa welding ne roll welding, iyo inoshanda zvakanyanya uye inoshandiswa zvakanyanya.
Iyo nyukireya vacuum mavharuvhu anogadzirwa nekambani yedu anoshandiswa munzvimbo dzeuranium fluoride uko yepakati inobvira, inoputika uye ine radioactive. Iwo mabhero akagadzirwa ne1Cr18Ni9Ti ane ukobvu hwe0.12mm. Iwo akabatana nevhavha disc uye gland ne roll welding. Iyo weld inofanirwa kuve yakavimbika yekuisa chisimbiso kuita pasi pekumanikidzwa kwakati. Kuti ugadzirise uye ushandure iripo roll welding midziyo kuti isangane nezvinodiwa zvekugadzira, dhizaini yekugadzira uye maitiro ebvunzo akaitwa, uye mhedzisiro yakanaka yakawanikwa.
2. Roll welding midziyo
Iyo FR-170 capacitor simba rekuchengetera roll welding muchina inoshandiswa, ine simba rekuchengetedza capacitor simba re340μF, yekuchaja voltage inogadzirisa huwandu hwe600 ~ 1 000V, electrode pressure kugadziridza renji ye200 ~ 800N, uye yezita yakanyanya kuchengetwa ye170J. . Muchina uyu unoshandisa zero-yakavharirwa kuumbika dunhu mudunhu, izvo zvinobvisa zvakaipira network voltage kushanduka uye kuona kuti pulse frequency uye yekuchaja voltage inoramba yakagadzikana.
3. Matambudziko nemaitiro ekutanga
1. Kusagadzikana welding process. Munguva yekugadzira, nzvimbo inoputika yakawanda, uye welding slag inonamatira nyore kune roller electrode, izvo zvinoita kuti zvive zvakaoma zvikuru kushandisa roller nguva dzose.
2. Kusashanda zvakanaka. Nekuda kwekuti mabhero ari elastic, weld iri nyore kutsauka pasina kumira zvakanaka, uye electrode iri nyore kubata dzimwe nzvimbo dzemabhero, zvichikonzera pfarivari uye kuparara. Mushure mevhiki yewelding, iyo weld inopera haina kuenderana, uye weld sealing haina kuzadzisa zvinodiwa.
3. Weld quality yakashata. Iyo weld point indentation yakadzika zvakanyanya, iyo pamusoro inopisa, uye kunyange chidimbu kupisa-kuburikidza kunoitika. Iyo weld mhando yakaumbwa yakashata uye haigone kusangana nezvinodiwa zvegasi pressure test.
4. Kurambidzwa kwemutengo wechigadzirwa. Mavharuvhu enyukireya anodhura. Kana kupisa-kuburikidza kukaitika, mabhero anoraswa, zvichiwedzera mutengo wechigadzirwa.
Xinfa welding midziyo ine hunhu hwemhando yepamusoro uye mutengo wakaderera. Kuti uwane ruzivo, ndapota shanya:Welding & Cutting Manufacturers - China Welding & Cutting Factory & Suppliers (xinfatools.com)
4. Kuongororwa kwemaitiro makuru ekugadzirisa
1. Electrode pressure. Kune rolling welding, kudzvanywa kunoshandiswa ne electrode pane workpiece yakakosha parameter inokanganisa kunaka kweweld. Kana iyo electrode pressure yakanyanya kuderera, ichaita kuti nzvimbo yenzvimbo inopisa-kuburikidza, kufashukira, kuputika kwepamusoro uye kupinda zvakanyanya; kana iyo electrode pressure yakanyanya, iyo indentation ichave yakadzika, uye deformation uye kurasikirwa kwe electrode roller ichakurumidza.
2. Welding kumhanya uye pulse frequency. Kune yakavharwa roll weld, iyo denser iyo weld mapoinzi, zviri nani. Iyo inopindirana coefficient pakati peweld points ingangoita 30%. Shanduko yewelding yekumhanyisa uye pulse frequency inokanganisa zvakananga shanduko yekupindirana mwero.
3. Kuchaja capacitor uye voltage. Kuchinja iyo yekuchaja capacitor kana yekuchaja voltage inoshandura simba rinotumirwa kune workpiece panguva yewelding. Iyo yekufananidza nzira yemaparamendi akasiyana ezviviri ane musiyano pakati pezvakasimba uye zvisina kusimba zvakatemwa, uye akasiyana emagetsi emagetsi anodiwa kune akasiyana zvinhu.
4. Roller electrode kupera chiso fomu uye saizi. Anowanzo shandiswa roller electrode mafomu anoti F mhando, SB mhando, PB mhando uye R mhando. Kana iyo yekupedzisira yakatarisana saizi ye roller electrode isina kufanira, ichakanganisa saizi ye weld core uye chiyero chekupinda, uye ichavawo nekukanganisa kwekuita kwewelding.
Sezvo zvinodiwa zvemhando ye roll weld joints zvinonyanya kuratidzwa mukuvhara kwakanaka uye kushorwa kwegora kwemajoini, pesvedzero yekupinda uye kupindirana mwero inofanirwa kutariswa pakusarudza iyo iri pamusoro apa paramita. Mune chaiyo welding process, akasiyana ma paramita anobata mumwe nemumwe uye anofanirwa kurongeka zvakanaka uye kugadziridzwa kuti uwane emhando yepamusoro roll weld majoini.
