Cold-drawn cylinder tube yog cov khoom siv high-precision steel yeeb nkab ua tiav los ntawm cov txheej txheem txias-daws. Nws yog tsuas yog siv los tsim pneumatic lossis hydraulic Cheebtsam, xws li lub tog raj kheej lossis roj kheej kheej.
Cov khoom siv steel yeeb nkab no muaj cov yam ntxwv hauv qab no:
Cold-drawn cylinder tubes muaj cov yam ntxwv ntawm tsis muaj oxide txheej ntawm cov phab ntsa sab hauv thiab sab nrauv, tsis muaj dej ntws los ntawm kev kub siab, siab precision, thiab siab smoothness.
Lub tog raj kheej txias-drawn raj adopts dov ua. Txoj kev ua haujlwm no tuaj yeem tsim cov txheej txheem ua haujlwm txias rau ntawm cov hlau nto, txo cov elastic thiab cov yas deformation ntawm kev sib cuag ntawm cov khub sib tsoo, thiab txhim kho qhov hnav tsis kam ntawm sab hauv phab ntsa.
