Mumakore ekuma1960 nekuda kwekugadzirwa kwechigayo chitsva-chakakwirira chakaenzana (chinozivikanwa sechigayo cheTransval), nzira idzi dzakasimukira nekukurumidza.Gayo idzva rinoonekwa nekukasira kutenderera kweiyo inopinda kuenda kumashure iyo rack rack inouya kuzochinja kutenderera Angle, nokudaro ichidzivirira muswe kubva mukuumba mativi matatu ayo anoita kuti rudzi rwechigadzirwa chiyero chekunze dhayamita kumadziro ukobvu kunowedzerwa kubva pa12 kusvika 35, iyo isingakwanise chete kugadzira matete-ane masvingo machubhu, asi zvakare kugadzirisa kugona kwekugadzira.

Iyo yetsika nzira yepombi jacking ndeyekuti iyo billet inopetwa nekumanikidza kwemvura uye inowedzeredzwa kuita mukombe mvere nekuyambuka irikuyerera chubhu umo marefu mandrel anoiswa mukati mezasi kwekapillary mukombe nepush tambo uye zvishoma nezvishoma kuderedzwa kuburikidza nhevedzano yemakomba diki rwakapetwa - mhando kufa furemu, yepamusoro yakakungurutsirwa mumachubhu.Rudzi rweiyi nzira yekugadzira ine mari shoma mumidziyo uye inogona kushandiswa kuenderera ichikanda billet, inogona kuburitsa dhayamita inosvika 1070mm, iyo mukobvu wemadziro kusvika 200mm yeiyo yakawedzera gobvu pombi, asi yakaderera kugadzirwa kunyatsoshanda, rakakora madziro, ipfupi pombi kureba kupfuura kushanda nemazvo Mushure mekubuda kweiyo nyowani CPE maitiro, asina chinhu machubhu anoputirwa nekuyambuka kutenderera uye kuwedzeredzwa kuita machubhu nekumusoro kutenderera mushure mekuvhara, iyo inokunda echinyakare nzira.

Kumwe kukundikana kwekusina kugadzirwa kwepombi kugadzirwa yave nzira iri nani yekubatsira hupfumi.
Mukugadzira extrusion pombi, iyo yakasvuurwa billet inotanga kupetwa kana kugadziriswazve zvobva zvadziirwa neyakaiswa iyo yekugezesa yemunyu inopisa, uye iyo yemukati nzvimbo yakaputirwa nemafuta uye inodyiswa mukati mekunze, kuburikidza negomba rekufa uye kuburikidza nesimbi iyo annular gap pakati pemandrel inosvinwa mumachubhu esimbi.

Inonyanya kushandiswa kugadzirwa kwepasi epurasitiki superalloy mapaipi, akakosha-akaumbwa mapaipi, macomputer akasanganiswa uye ane machubhu machubhu simbi pombi, nezvimwewo Iyi nzira ine dzakasiyana siyana dzekugadzira, asi yakaderera goho.Mumakore apfuura, nekuda kweforoma zvinhu, lubricants, extrusion kumhanya uye zvichingodaro zvakagadziridzwa, extrusion pombi yekugadzira yakagadzirawo.

Iyo inotungamira coil rolling chubhu inonziwo Diessel perforated capillary chubhu ine refu mandrel yakaonda madziro simbi machubhu akakungurutswa pane anotungamira ndiro chigayo.Achigayo chakafanana neyaviri - yakakwira muchinjikwa - kutenderera chibhakera kunze kweiyo yakagadzika giraidhi ndiro inoshandurwa kuita inoshanda giraidhi ndiro Seyakareba mandrel kugadzirwa, simbi chubhu yemukati madziro yakatsetseka, uye hapana kukwenya; Asi chishandiso mutengo wakakura, gadziridza yakaoma.Iyo inonyanya kushandiswa kuburitsa 150mm yekunze dhayamita kabhoni simbi machubhu kune anotevera akajairika USES.Pari zvino, kashoma kushandiswa uye haina tarisiro yakakura yekusimudzira.

Kukosa chubhu kugadzirwa ichave yakati sandara kana isina mhango isina chinhu mumuchina wekutenderera kuburikidza neumwe kana kupfuura kutenderera kwakagadzirwa kwakatetepa-kwakakomberedzwa simbi pombi.High nemazvo, akanaka mehendi zvivakwa, zvakasiyana siyana zviyero, asi kugadzirwa kwekuita kwakaderera.Mainly inoshandiswa mukugadzira kweasina -ferrous simbi simbi pombi, asi zvakare zvakanyanya uye zvakanyanya kushandiswa mukugadzira.

Kunze kwemidziyo yemumba, makemikari makemikari uye zvikamu zvemuchina, zvinonyanya kushandiswa mumaindasitiri emauto.
Muma1970s, kushandisa nzira yakasimba yekutenderera yakakwanisa kuburitsa pombi dhayamita inosvika pa6000mm, dhayamita uye ukobvu hwemadziro chiyero cheanopfuura 10000 hombe dhayamita mutete mutete uye yakaumbwa pombi fittings.
Kutonhora kutonhora, kudhirowa dhizaini dhizaini yekugadzira diki dhayamita nhete madziro, kunyatsoita uye yakasarudzika-yakaumbwa simbi pombi.raw yekugadzira maficha ari akawanda - maitiro kutenderera maitiro.

Muma1960, yakatanga kukura munzira yekumhanya-mhanya, mitsara-yakawanda, sitiroko refu uye chubhu refu isina chinhu.Uyezve, diki-roll roll inotonhora pombi chigayo yakagadziridzwa, iyo inonyanya kushandiswa kugadzira yakanyanyisa kuonda chaiyo simbi pombi ine madziro ukobvu asingasviki 1mm. Cold inotenderera michina yakaoma, chishandiso kugadzirisa chakaoma, uye akasiyana uye magadzirirwo ekushandura haachinjike. Iyo yakasanganiswa maitiro ekutonhora kutonhora uye kutonhora kudhirowa inowanzo gamuchirwa, ndiko kuti, madziro anotanga kuderedzwa nekutonhora kutenderera kuti uwane yakakura deformation, uyezve akasiyana mageji anowanikwa nekutonhora kudhirowa lattice.
