T8 carbon steel cold rolling production device

Abstract

The invention relates to the technical field of T8 carbon steel cold rolling, and discloses a T8 carbon steel cold rolling production device which comprises a base, a box body is fixedly connected to the upper end of the base, roll shafts are symmetrically and rotationally connected to the box body through two first bearings, the shaft walls of the two roll shafts located in the box body are fixedly sleeved with an upper cold roll and a lower cold roll correspondingly, the shaft walls of the two roll shafts located outside the box body are fixedly sleeved with large gears, the two large gears are meshed with each other, one side of the base is fixedly connected with a mounting plate, and the two roll shafts are rotationally connected with the mounting plate through two bearings. According to the T8 carbon steel cold rolling production device, before a T8 carbon steel strip is subjected to cold rolling machining, impurities attached to the T8 carbon steel strip can be removed, so that the flatness of the T8 carbon steel strip rolled by a cold rolling roller is prevented from being affected, and the T8 carbon steel strip can be evenly coated with anti-rust oil, so that the anti-rust effect on the T8 carbon steel strip is better.

Description

technical field [0001] The invention relates to the technical field of cold rolling of T8 carbon steel, in particular to a production device for cold rolling of T8 carbon steel. Background technique [0002] T8 carbon steel is high-carbon steel with a carbon content of 0.75-0.84%. It is usually used for various tools that require high hardness and wear resistance, such as molds and punches with simple shapes, tools for cutting metal, and woodworking tools. Secondary tools such as milling cutters and knitting needles for textiles. In the production process of T8 carbon steel strip, cold rolling is required. [0003] Cold rolling is to use hot-rolled steel coils as raw materials. After pickling to remove scale, continuous cold rolling is carried out. The finished product is hard rolled coils. Due to cold hardening caused by continuous cold deformation, the strength, hardness, and toughness of hard rolled coils increase. The plastic index decreases, so the stamping performanc...
