Pombi yesimbi isina musono inodhonzwaari aprecision inotonhora-inodhonzwa seamless simbi pombiine yakakwira dimensional kurongeka uye yakanaka yekumusoro kupedzisa kwema mechanical chimiro uye hydraulic michina.Kusarudza chaiyo seamless simbi pombikugadzira michina chimiro kana hydraulic michina inogona kuchengetedza zvakanyanya nguva yekugadzira, kuvandudza chiyero chekushandiswa kwezvinhu uye kugadzirisa mhando yechigadzirwa.
Kuti uwane mapaipi esimbi asina musono ane saizi diki uye mhando iri nani, kutonhora kutenderedza, kutonhora kudhirowa kana nzira mbiri dzinofanirwa kutorwa.Cold rolling inowanzoitwa pachigayo chepamusoro-mbiri, uye mapaipi esimbi asina musono anokungurutswa mune annular pass akaumbwa neinosiyana-siyana-chikamu denderedzwa groove uye yakagadziriswa conical plug.Kudhirowa kutonhora kunowanzoitwa pa 0.5 ~ 100T imwe-cheni kana kaviri-cheni inotonhora yekudhirowa muchina.
2. Iyo inotonhora-inokwevera seamless simbi pombi chigadzirwa chakabuda mumakore achangopfuura, kunyanya nokuti mukati megomba uye kunze kwemadziro emadziro ane kushivirira kwakasimba uye roughness.
Zvimiro zveinotonhora-inodhonzwa (yakakunguruka) isina musono pombi yesimbi:
1. Diki rekunze dhayamita.2. Kururamisa kwakakwirira kunogona kushandiswa pakugadzirwa kwebatch diki 3. Kunyatsonaka kwekutonhora kunotorwa (yakakungurutswa) zvigadzirwa uye kunaka kwepamusoro.4. Nzvimbo yemuchinjikwa yepombi yesimbi isina musono yakanyanya kuoma.5. Kuitwa kwepombi yesimbi isina musono yakakwirira, uye simbi inenge yakaoma.Seamless simbi mapaipi ezvivakwa(GB/T8162-2008) mapaipi esimbi asina musono ezvimiro zvakajairwa uye zvimiro zvemichina.Irwo rudzi rwepombi yesimbi isina musono inorongwa maererano nemashandisirwo ayo akasiyana.Kuwanda kwekushandisa kunosanganisira marudzi ese emapombi esimbi asina musono anoshandiswa mune zvakajairwa zvimiro uye michina zvimiro, pamwe nenhamba huru yemaindasitiri akadai sekuvaka, michina, zvekufambisa, ndege, kushandiswa kwemafuta, nezvimwe.
Misiyano mikuru pakati peannealing uye normalizing:
1. Chiyero chekutonhodza che normalizing chinokurumidza zvishoma kudarika che annealing, uye dhigirii ye supercooling yakakwirira 2. Iyo microstructure inowanikwa mushure mekugadzika kwehutano hwakanaka, uye simba uye kuoma kwakakwirira kudarika iyo ye annealing.
Sarudzo yeannealing uye normalizing:
1. Normalizing inowanzo shandiswa pachinzvimbo chekuvharisa pombi dzesimbi dzisina kabhoni dzine kabhoni isingasviki 0.25%.nokuti
Nekukurumidza kutonhora kutonhora, inogona kudzivirira iyo yakaderera-kabhoni seamless simbi pombi kubva pakuparadzanisa pamwe nemuganho wezviyo uye kutama kwekatatu kwecarburization Kuvandudza kutonhora deformation kuita kwezvikamu zvekutsika;Normalizing inogona kuvandudza kuoma kwesimbi
Machinability kabhoni musono simbi pombi;Kana pasina imwe nzira yekupisa kupisa, normalizing inogona Kunatsa zviyo uye kuvandudza simba repasi-kabhoni seamless simbi pombi.
2.Medium-carbon inotonhora-inodhonzwa seamless simbi pombiine carbon content pakati pe 0.25 ne 0.5% inogonawo kutsiviwa ne normalizing
Tsiva annealing, kunyangwe iyo kuoma kweinotonhora-inodhonzwa seamless simbi pombi yepakati kabhoni simbi padhuze nepamusoro muganho weiyo kabhoni yemukati yakakwira zvishoma mushure me normalizing Yakakwira, asi inogona kutemwa, uye mutengo wekujaira wakadzikira uye kugadzirwa kwacho kwakakwira. .3.Iyo inotonhora-inodhonzwa seamless simbi pombi ine kabhoni yemukati pakati pe0.5 ne0.75% ine yakakwira kabhoni yemukati,
Iko kuomarara mushure mekugara kwakakwira zvakanyanya kupfuura iyo yeannealing, saka zvakaoma kuita kucheka, saka kazhinji Shandisa annealing yakakwana kuderedza kuoma uye kugadzirisa machinability.
4. High carbon kana tool steel ine carbon content ＞ 0.75% yepombi inodhonzwa isina musono pombi inowanzotora bhora Chemical annealing inoshandiswa sekutanga kupisa kupisa.Kana paine network yechipiri simenti, inofanira kuitwa kutanga kubviswa kweMoto.Anealing ndeyekupisa iyo inotonhora-inodhonzwa seamless simbi pombi kune chaiyo tembiricha uye kuichengeta kwenguva yakati, Kupisa kurapwa maitiro nekunonoka kutonhora.Kunonoka kutonhora ndicho chinhu chikuru chekuvharisa, uye kudhirowa nekutonhora hakusi Kazhinji, pombi yesimbi yemusono inotonhodzwa kusvika pasi pe550 ℃ muchoto.Annealing inoshandiswa zvakanyanya Kupisa kupisa kwakanyanya kunowanzoshandiswa sekugadzirira mukugadzirwa kwechigadzirwa chekushandisa kana mechanical zvikamu. , uye gadzirirai nzira inotevera.
Chinangwa cheAnealing: ① kuderedza kuoma kwepombi yesimbi isina musono inotonhorwa kufambisa machining;② Bvisa marudzi akasiyana-siyana Kushushikana kudzivirira deformation yepombi yesimbi isina musono inotonhora;③ Natsa zviyo zvakakora uye uvandudze chimiro chemukati Gadzirira kurapwa kwekupisa kwekupedzisira.
