Electroslag nomoto: zvakasiyana-siyana uye mamiriro

Welding kuvhiyiwa vane simbi dziri kunyanya inobva kwemakemikari-chafariz utsotso pezvakaitwa. Zvichienderana pamusoro tooling kushandiswa, zvinoshingaira consumables uye kazhinji hwokugadzira sangano acho ezvinhu, uye kuchinja maitiro kunoguma chigadzirwa. The chikuru basa iri ndiri weredha ndiko kuumba rakasimba vadyi kuti anogona kukunda mitoro iyo vachawa pamusoro mukuru marongerwo. Panyaya iyi, electroslag nomoto hakusi chinetso nhasi iripo somunhu dzenhoroondo yemagetsi riemukaari nezvemidzimu anobvumira paumbwe nani. nokuda mberi nokushanda vazvo. Zvisinei, kushandisa bhati gang itye muitiro kunopa zvimwe zvakawanda iro makambani makuru anoshandisa ruzivo urwu.

Pfupiso electroslag nomoto

Nzira electroslag nomoto kwakavakirwa kushandiswa kupisa riri yakawanikwa panguva uchanyangadika zvinhu. The zvichiguma chafariz simba uye pakudaro anoita chinhu inopa nomoto oparesheni. Sezvo zvinhu riri kuumbwa, iri pasi, gang akashandisa hwaro. The causative mutumwa uchanyangadika kwacho kuri Magetsi, saka chaiwo jenareta zvaishandiswa nedanho sangano. Chaiwo zviri kwacho zvinosanganisira chokwadi chokuti electroslag nomoto kunogona kuitwa chete hunyambiri placement preforms. Achifuridzirwa kupisa wakadenha emura simbi, iyo yakaumbwa mumakore reflow electrode waya welded okunze uye anozadza nzvimbo pakati penhindi. Kuti uchengete mvura gang uye simbi kugeza rokurara nokupararira, nemitambo yakasiyana kushanda kugeza kuisa two chilled mvura nemasiraidhi. Sezvo nomoto musono vanomutsirwa uye musapa vakawanda chokubuda kushanda.

gadzira

It kunotanga riemukaari nomoto muitiro excitation, izvo chichagadzirirwa pakati penhengo uye electrode waya. The chafariz simba pamusoro chinhu chakakombama inonyunguduka zvinoyerera, uye ipapo anosika chaizvo gang kugeza, pachiyero iyo vachamutswa. Nokuda zvinhu magetsi conductivity, fused kokuyerera anotanga shunt yacho chinhu chakakombama, kumbomira kwaro. Kana ichi utsotso uye kudziyisa akaramba zvinoyerera nokuda chafariz zvinokonzerwa, izvo ano kunobva chiito vaipa kune mvura gang. Ndiyo electroslag nomoto rikurumidze kwakavakirwa kuchinjwa kupisa kubva gang, asi chete anosunungura simba kubudikidza uno, asi anogona zvakananga uchatamisa ayo zvikamu kushanda.

The electrode uye simbi chipfuro vari interconnected pachishandiswa chaizvo gang kugeza. Next achiumbwa uye simbi kugeza. Izvi kungada zvikamu zvakasiyana, zvichienderana zvinhu unhu. Chinhu chinokosha ndechokuti simbi mvura nechigadziko riri yakaderera pachiyero gang kugeza, asi kunoda akwirwe Kuumbwa sliders pakudzora leakage. Nokuti chinangwa ichi, kuti sliders zvemhangura, haachandidi nemvura.

siyana nomoto

Nzira ezvidzidzo nzira iyi siyana mune mhando electrode kushandiswa. Somuenzaniso, mashoko dzekare zano kunosanganisira kushandisa nomoto waya iro zvokudya sezvo akanyauka kuti gang kugeza. In kusvika ichi, tenzi anofanira kuzivisa electrodes uyewo reciprocating chinjikira inofamba, iyo inopa dzakafanana kudziyisa of welded zvikamu rose ukobvu.

Chimwe nzira kunosanganisira kushandisa electrodes makuru muchinjikwa chikamu kana kwamahwendefa. Panyaya iyi, iyo electrode achava nenzvimbo dzakawanda nzvimbo inoumbwa musiyano uri pakati workpieces. Kushandisa Mahwendefa achatambanudzirawo. In akadaro zano electroslag nomoto rinoitwa pamwe netarisiro ndeiya yakaita tsamba kubva vanoshingaira zvinhu zvakadzama. Zvisinei, chimiro chavo chinofanira kuva akafanana welded workpiece. A muedzo ndiro wakaiswa pakakoromoka uye zvichienderana mamiriro ari gang bhati zvinogona kusvitsa kuti basa nzvimbo sezvo oparesheni.

Welding midziyo

Sezvinoita kwakajairika yemagetsi ongororo, muchiitiko ichi, rinokosha midziyo. Kuti uone zvachiri zvinofanira kucherechedzwa kuti electroslag unyanzvi, kusafanana nedzimwe nzira zvakafanana nomoto anogona chinozoiswa pamwe kuitika arambe achirema pamusoro 0.1 A / mm ^2, iyo kakawanda madiki kupfuura chete chinhu chakakombama nzira. Kuti aite basa iri kushandisa michina zvakafanana vakawanda zvinodiwa. Chokutanga chidobi ndiko nechokwadi kuti musiyano uri pakati akasiyana micheto ari tabhu. Mamiriro yechipiri zvinoratidzwa chokwadi kuti zvokushandisa electroslag nomoto vanofanira kubvumira paumbwe imwe tote welded musono. Uye yokupedzisira chinokosha mamiriro ndechokuti nomoto kunofanira kuitwa imwe nzira. Sezvo mamwe midziyo rinoshandiswawo waya inosimbisa rollers, achivapa ano-itaure emasiraidhi nezvipfigiso uye sepombi kuti kutonhora mvura.

Welding Consumables

The rinoita umbowo nomoto kwakadaro - vakati electrodes, izvo zvinogona kuita zvakawanda pazvinhu namasanhu. Chikafu kuti gang bhati anopiwa kugara nokukurumidza. Uyezve gang uye electrodes ringashandiswawo utsotso itaure. Zvichienderana zvinodiwa kugamuchira zvabuda, kuti opareta anogona kudzora consumables zvokuti muitiro chichaitwa pamwe kunosiyana inosiyana kuchinyanya - Kurangwa bata pamwe chete electrodes kuvandudza nokudziya iri akaita maererano mhando zvesimbi. Kazhinji, semaonero yakaoma kuna tenzi, zvakaoma zvikuru nedanho electroslag Welding ane kuonana chokupfeka musimboti. Kazhinji, gang-kuonana unyanzvi rinoshandisirwa muzviitiko kana zvakakodzera kuti weld mbariro kuti planar pemvura.

zvakanakira mabikirwo

Chimwe chikuru mukana nzira kukwanisa weld pasina kudikanwa asati kupatsanurwa micheto, nokuti muitiro chaitwa nokuvapo musiyano uri pakati kushanda zvikamu anosvika 3 cm. Uyewo Welding electroslag ane mukuru coefficient pakati nomoto, chinoguma uye zvakanakira zvemari sezvo nemari iri chiitiko sangano. Benefits vachapiwa akanzwa pashure pokupedza oparesheni. Chokwadi uyu mhando nomoto inopa zvakafanana, ichibata urongwa vagari hama kuti akabatana. chikonzero Kanoita paumbwe chisina kutsetseka deformation, izvo pakupedzisira nyore kugadzwa zvikamu chete kuchinja yavo.

Minda chikumbiro

Mukana kushandisa nzira iyi rinorondedzerwa so nguva yayo kutadza. Nzira Izvi hazvibatsiri kuzoshandisa mhando dzakawanda nomoto. Kakawanda, unyanzvi hwokugadzira rinobatanidzwa pakuvaka uye maindasitiri mafomu. Somuenzaniso, kugadzirwa hombe puranga, kugadzwa turbine zvokushandisa, kugadzwa ngoma gobvu-akavakirirwa uye bhaira zviyero - izvi chete chikamu nevakariri remapazi umo Electro-gang nomoto inoshandiswa. Kushandiswa nzira iyi pakuburitswa anobvumira kuti vaungane zvivako zvakakura. Musiyano mukuru pakati electroslag mitoo kubva dzimwe nzira mashoko esimbi zvinhu ndiko kubvumira mukana kutsiva ndokugadzira kana kukandira zvikamu welded muhombe dzomuzana, akagadzirwa castings diki kana forgings.

mhedziso

Nokuda kwezvikonzero zvakasiyana-siyana, kunyange chipfuro munzvimbo ruzivo urwu haisi nguva dzose anobvumirwa kushandiswa kwayo. Kurambidzwa Anonyanyowanika chokuita kwesayenzi kukanganisa kuti vangashandisa nzira seisingashandi. Somuenzaniso, Electro-gang nomoto ichava basa kana vakaronga kushandisa panzvimbo, apo panewo tisanzwe chafariz kushushikana zvokuvakisa. Kureva, nezvikonzero zvemari uye kunaka inowanikwa michina anoruramiswa, asi pane imwe nuance. mumwe nomoto mapazi kwakadaro dzinoratidzwa yakakwirira chafariz simba, ukuwo, mune mira urongwa zvinhu zvose zvine zvinhu navo vacharaswa pasi simba chafariz migumisiro.
