Manufacturing Nzira

(1) Nzira yekugadzira simbi
Simbi inogadzirwa nechoto chemagetsi, okisijeni inoshandura kana yakavhurika nzira yekupisa.

(2)Kugadzira nzira yechubhu isina chinhu
Iyo chubhu isina chinhu inogona kugadzirwa nenzira inopisa yekutenderedza, uye inoenderera ichikanda billet kana ingot yesimbi inogona kushandiswa zvakare.

(3)Kugadzira nzira yesimbi pombi
Iyo pombi yesimbi inogona kugadzirwa nekupisa kunopisa (extrusion, kuwedzera) kana kutonhora kudhirowa (rolling) seamless nzira.

Testings

(1)Hydraulic test
Iyo pombi yesimbi inofanirwa kuongororwa hydraulically imwe neimwe.

(2)Kupfava bvunzo
Mapombi esimbi ane dhayamita rekunze rinopfuura 22mm kusvika 400mm uye ukobvu hwemadziro husingadarike 10mm huchaitwa bvunzo dzekuti flatten.

(3)Kuedza kuedza
Iyo pombi yesimbi ine madziro emadziro asingasviki 8 mm inogona kuiswa pasi pekuedzwa kwemoto nepamusoro taper ye30 °, 45 ° kana 60 °.

(4) Kupeta bvunzo
Mapombi esimbi ane dhayamita yekunze isingapfuuri 22 mm achaiswa bvunzo yekukotama.

(5)Kuedza kusina kuparadza
Zvinoenderana nezvinodiwa nemutengi, iyo pombi yesimbi ichave yakaedzwa ultrasonically imwe neimwe.
