Cold drawn seamless tube defects panguva yekuita

Cold drawn seamless chubhuinofanira kunge iine humwe hurema uye nyaya dzemhando mukugadzira, izvo zvinoda kutariswa zvakanyanya. iripo simbi fibrous tishu pamwe nekumisikidza, vacancies uye humwe hurema hwekristaro, hunowanzo endeswa kune annealing kana normalizing kupisa kupisa kunoreva kuzvibvisa.Chinangwa chekugadzirisa ndeyekunatswa kwezviyo, masangano anobvisa kukanganisa, kuderedza kuoma, plastiki, uye zvakare kufambisa kutonhora.Cold yakadhirowewa isina musono simbi pombi kugadzirwa, annealing midziyo yakakosha kugadzira yakakodzera annealing maitiro ndeye kuona kuti inotonhora inodhonzwa isina musono simbi pombi inokodzera sangano, chigadzirwa hachisi chinhu chinodiwa chekutyoka kuremara.Kana mugadziri kune rimwe divi kuderedza kugadzirwa mutengo, kuderedza annealing muitiro anosungirwa kukanganisa kunaka kwezvigadzirwa.

Cold yakadhirowewa isina musono chubhu deformation idiki kwazvo, haigone kusvika kumusoro kumagumo uye dimensional kunyatsoita zvinodiwa, ivo havagone kuwana iyo simba index yechikamu;deformation yakakura kwazvo, isina musono chubhu yepurasitiki, kusimba kunoderera zvakanyanya, uye yakawandisa zviyo zvinodhonzwa zvitete, kuumbwa kwefibrous tissue, simbi ichava yakakosha anisotropy.Cold yakadhirowewa isina musono simbi chubhu axial, yakaenzana kune yakarebesa nzira yezviyo, simba rinowedzera;inotonhora inodhonzwa isina musono machubhu eiyo radial uye perpendicular kune yakarebesa nzira yezviyo, asi yakadzikira simba, uye iyo hydraulic cylinder kushushikana kuri radial museamless simbi pombi, saka deformation yakakura kwazvo kuti ipe kutamba kwakazara kuita kwekuita. inotonhorera inodhonzwa pombi.

Pombi yesimbi inotonhora

Cold yakadhirowewa simbi pombi inoshandiswa pakugadzira michina, hydraulic dhizaini, yakakwira dimensional kurongeka uye kupera kwepamusoro, yakanaka chaiyo inotonhora inodhonzwa isina musono chubhu.Kushandisa chaiyo isina musono chubhu kugadzira muchina chimiro kana hydraulic michina, nezvimwewo, inogona kuderedza zvakanyanya nguva yekugadzira michina, kugadzirisa. kushandiswa kwezvinhu, uye kubatsira kuvandudza chigadzirwa chemhando.

Kana iine saizi diki uye nani mhando isina musono machubhu, inofanirwa kutora inotonhora-yakakungurutswa, inotonhorera inokwevera kana nzira dzese.Cold yakakungurutswa kazhinji mu-two-roll mill, simbi inokunguruka mumhete inopfuura inochinja-chinja-chikamu gomba slot uye yakagadziriswa koni musoro.Kudhirowa kunotonhora kunowanzo kuve mu 0.5 ~ 100T imwechete cheni kana kaviri ketani yekudhirowa muchina.
