Ndezvipi zvinhu zvinoshandiswa kugadzira?

Zvishandiso zvekugadzira zvakanyanya zvinosanganisira kabhoni simbi uye alloy simbi ine akasiyana maumbirwo, ichiteverwa nealuminium, magnesium, mhangura, titanium uye alloys avo. Mamiriro ekutanga ezvigadzirwa anosanganisira bar, ingot, simbi poda, uye simbi yemvura. Chiyero chemuchinjiko-chikamu chesimbi chisati chachinja kuenda kunzvimbo yakachinjika mushure medeformation inodaidzwa kuti forging ratio. Sarudzo chaiyo yeforging reshiyo, inonzwisisika yekupisa tembiricha uye nguva yekubata, inonzwisisika yekutanga uye yekupedzisira yekubikira tembiricha, inonzwisisika deformation huwandu uye deformation kumhanya zvine hukama zvakanyanya nekuvandudza kunaka kwechigadzirwa uye kuderedza mitengo.

Kazhinji, denderedzwa kana sikweya bar zvinhu zvinoshandiswa sezvivharo zvezvidiki uye zvepakati-saizi forgings. Chimiro chezviyo uye michina yemidziyo yebhari yakafanana uye yakanaka, ine chimiro uye saizi chaiyo, yakanaka yemhando yepamusoro, uye iri nyore kuronga kugadzirwa kwakawanda. Chero bedzi tembiricha yekudziya uye deformation mamiriro akadzorwa zvine hungwaru, emhando yepamusoro forgings inogona kugadzirwa pasina yakakosha deformation. Ingots inongoshandiswa pakugadzira kukuru. Ingot chivakwa chakakandwa chine hombe columnar makristasi uye yakasununguka nzvimbo. Naizvozvo, zvinodikanwa kupwanya iyo columnar makristasi kuita zviyo zvakatsetseka kuburikidza nehombe yepurasitiki deformation, uye compact iwo zvakasununguka kuitira kuti uwane yakanakisa simbi chimiro uye michina zvinhu.

Powder metallurgy preforms inoumbwa nekutsikirira uye kupfura inogona kugadzirwa kuita hupfu hwekufukidzira nekusina flash forging munzvimbo inopisa. Iyo density yehupfu yehupfu iri padyo neiyo ye general die forgings, iine yakanaka ma mechanic zvivakwa uye yakanyanya kurongeka, izvo zvinogona kuderedza kunotevera kucheka kugadzirisa. Iyo yemukati chimiro cheupfu forgings yunifomu pasina kupatsanura, uye inogona kushandiswa kugadzira magiya madiki uye mamwe maworkpiece. Nekudaro, mutengo wehupfu wakakwira zvakanyanya kupfuura iwo weiyo general bar zvinhu, izvo zvinomisa kushandiswa kwayo mukugadzira. Nekushandisa static pressure kune yemvura simbi yakadururirwa mugomba remuvhu, inogona kusimba, kupenya, kuyerera, kuita deformation yepurasitiki, uye kuumba pasi pekumanikidzwa kuwana chimiro chaunoda uye zvimiro zvekugadzira. Liquid metal forging inzira yekugadzira pakati pekufa kukandira uye kufa forging, kunyanya yakakodzera kune dzakaomarara dzakatetepa-madziro zvikamu zvinonetsa kuumba ne general die forging.

Pamusoro pezvakajairwa zvinhu senge kabhoni simbi uye alloy simbi ine akasiyana maumbirwo, zvekugadzira zvinhu zvinosanganisirawo aluminium, magnesium, mhangura, titanium, uye alloys avo. Iron based high-temperature alloys, nickel based high-temperature alloys, uye cobalt based high-temperature alloys anogadzirwawo kana kukungurutswa se deformation alloys. Zvisinei, aya alloys ane nzvimbo dzakatetepa dzepurasitiki, zvichiita kuti kuumba kuome. Zvishandiso zvakasiyana zvine zvinodiwa zvakasimba zvekupisa tembiricha, tembiricha yefogi, uye tembiricha yekupedzisira yekugadzira.
