Hot-yakakungurutswa seamless simbi pombi

Maitiro ekupisa-akakungurutswa seamless simbi pombi:

Kupisa-yakakungurutswa isina musono simbi pombi yekugadzira base deformation process inogona kupfupikiswa sematanho matatu: perforation, kuwedzera uye kupedzisa.

Billet inodyiswa muchoto chekupisa, tembiricha inenge 1200 degrees Celsius.Mafuta ehydrogen kana acetylene.Iyo tembiricha yekudzora tembiricha yakakosha kupfeka mhepo chubhu kutenderera, mushure mekuburitswa kwekumanikidza puncher.ayo anowanzo ajairika puncher tapered roller punch iyi, yakakwira kugadzirwa kwakanaka, mhando yechigadzirwa, perforated kuwedzera vhoriyamu, kupfeka akasiyana simbi.Mushure mekuputika, chubhu yakatenderedzwa yanga iri matatu-roll cross rolling, rolling kana extrusion.

Kazhinji kugadzirwa kwepombi yesimbi isina musono inopisa: mbariro → kudziyisa → kubaya → matatu-michinjiko inokunguruka, kukunguruka kana kuburitsa → yakavharwa → saizi (kana kuderedza) → kutonhora → chubhu yeparison → kutwasanudza → hydrostatic bvunzo (kana kuona kukanganisa) → maka → kuchengetedza.

Mushure mekubvisa pombi saizi.Sizing mill nekumhanya-mhanya kwekoni dhiri muBillet punch kugadzira pombi yesimbi.Iyo simbi pombi yemukati dhayamita inotarirwa nehurefu hwekunze kwedhayamita ye sizing mill drill.Mushure mekuita saizi, pombi yesimbi yekupinda mushongwe yekutonhora nemvura yekupfapfaidza kutonhora, iyo pombi yesimbi mushure mekutonhora, inofanirwa kutwasanudza.Yakatumirwa nepombi yekutakura nekutwasanudza muchina wekuona simbi (kana kuti hydrostatic bvunzo) kuita kukanganisa kwemukati.Simbi pombi dzemukati nyaya dzakadai makatsemuka, mabhuru anozoonekwa.

Zvakanakira

hot yakakungurutswa seamless simbi pombi inogona kukuvadza yakakandwa microstructure yesimbi ingot, kunatsiridza kwekristaro tsanga dzesimbi, uye kubvisa hurema hweiyo microstructure, kuitira kuti iyo simbi sangano compacting, ivandudze michina zvimiro.Kuvandudzwa uku kunoratidzwa mugwara rekukunguruka, zvekuti simbi haisisiri kune imwe nhanho isotropic;kudurura kuumbwa kwemabhuru, kutsemuka, uye osteoporosis, pasi pekushisa kwepamusoro uye kumanikidzwa kunogonawo kubatanidzwa pamwe chete.

Zvakaipa:

1. Mushure mokupisa kunopisa, iyo isiri-metallic inclusions mukati mesimbi (kunyanya sulfides uye oxides, pamwe chete nesilicate) yakamanikidzwa mupepa, stratified (laminated) phenomenon inooneka.Kuiswa kwesimbi muhukobvu kwakanangana nekudhonza kuita kwakadzikira zvakanyanya, uye kunogona kuoneka mu weld shrinkage interlayer kubvaruka.Weld shrinkage inokonzeresa strain yemunharaunda kazhinji inosvika kakawanda iyo goho point strain, iyo dhizaini yakakura kupfuura mutoro wakakonzerwa;
2. Residual stress inokonzerwa nekutonhodza kusina kuenzana.Kushungurudzika kwasara ndiko kushushikana kwemukati-yega-chikamu kuenzana mukusavapo kwesimba rekunze, simbi inopisa-yakakunguruswa yemhando dzakasiyana-siyana dzakasara dzine kushushikana kwakasara kwakadaro.Residual stress is self-phase equilibrium, asi nhengo dzesimbi mukuita kwekunze kwesimba kana dzine imwe pesvedzero.Zvakadai se deformation, kugadzikana, anti-kuneta kunogona kukanganisa.
3. Zvigadzirwa zvesimbi zvinopisa, kudzora kwakashata kwehupamhi uye kumucheto kwehupamhi.Isu tinoziva nezvekuwedzera kwekupisa uye kuderera, kunyangwe kutanga kwekupisa-yakakungurutswa kunze kwakajairika kureba, ukobvu, kana pachave neakaipa yekupedzisira mushure mekutonhodza, iyi yakashata yekusiyanisa mupendero hupamhi yakafara kuwedzera kukura kwekuita kweiyo zviri pachena.

Saka kune simbi huru yesimbi kumucheto kwehupamhi, ukobvu, kureba, kona, uye mutsara weparutivi hapana mutemo unoda kunyatsojeka.

Kukanganisa kweHot-yakakungurutswa Seamless Simbi Pipe:

Kuparadzana

Iri mukati mepamusoro pepombi yesimbi yaive yakatwasuka kugovera, yakasimudzwa helical, yakakura simbi kupatsanurwa kana kutyora-kufanana dissection.

Kutwasanuka kwemukati

Inowanikwa mukati mepamusoro pepombi yesimbi yaive yakatwasuka kugovera, ichiratidza symmetrical kana imwe mutsara-yakaumbwa yakapetwa ne kuburikidza nekureba, kune yenzvimbo.

Irregular gomba

Iri pamusoro pepombi yaive yakatwasuka kugovera, ① ine madziro maviri kana maviri 180 ° kunze kwekukora, kana pamusoro pepombi uye ukobvu hwemadziro enzvimbo yekuparadzanisa mandrel yakakora chimiro, inozivikanwawo seyemukati dhiramu kit. .② simbi yemukati gadheni yaive ine hexagonal yakaumbwa isina kuenzana ukobvu, inonziwo hexagon.

Wall contraction

Iri pamusoro pemukati wepombi yesimbi, simbi yakachinjika chikamu thinnest simbi pombi yemukati mepasi depressions, kutetepa kwenzvimbo kwemadziro ukobvu hwekukochekera kwakanyanya kupotsa kubvaruka.

Vanga rakakunguruka

Longitudinal kutungamira kwemukati pamusoro pezvipikiri zvesimbi senge mavanga, mapundu kana mapundu akapetwa yemukati pombi pepamusoro indentation.

Kupeta mukati

Inowanikwa mukati mechikamu chekupedzisira chepombi yesimbi, yemunharaunda kana flaky longitudinal spiral kana semi-spiral kupeta kusingaenzaniswi kugovera.

Kukunguruka

Iri mukati meiyo longitudinal pamusoro pemudhuri wepombi yakanga ine chidimbu kana kuti yakazara kureba mune yekunze concave kana convex corrugations pamusoro pekunze pepombi kuburikidza refu longitudinal grooves anorayira pachena symmetry, kazhinji rectilinear, munhu kuti slash chimiro.

Tear

Iri pachubhu longitudinal simbi pamusoro yairatidza madhigirii akasiyana-siyana ekutsemuka, gomba rakaita sedhaimani uye rakaita seovhari kuburikidza nemuviri wetubula.

Peta kaviri-slit

Iri pamusoro longitudinal pamusoro pepombi rusvingo obliquely achitambanudzira kupinda peya longitudinal makatsemuka, makatsemuka dzimwe nguva akapararira kuparadzirwa pamusoro pombi circumference dzimwe nguva kuonekwa symmetrical.

Kaviri pakati

Iri pamusoro longitudinal pamusoro pepombi rusvingo obliquely achitambanudzira kupinda peya longitudinal makatsemuka, makatsemuka dzimwe nguva akapararira kuparadzirwa pamusoro pombi circumference dzimwe nguva kuonekwa symmetrical.

Kupeta kwekunze

① papombi yekunze inopa yakagara yapeta katatu yakaita, yakapetwa kaviri yakatwasuka yakatwasuka kana isina kurongeka pepa rakapetwa.

② Kupa muchina wekusonesa unogara unoramba kana uripo-wakafanana kana wakadzedzereka 60 °, 120 °, 180 ° yekusonesa yakapetwa-yakapetwa pombi yakapetwa munzira refu yekunze.

③ yekunze longitudinal yakapetwa pane inotenderera simbi pombi.

④ kureba kwakananga kwepombi yepasi kuburikidza refu kana pfupi slash dot rakapetwa zvakakomba zvakadzika maviri kana matatu e120 °.
