Cold rolling mill roller surface treatment device

Abstract

The invention discloses a cold rolling mill roller surface treatment device. The device comprises a grinding box, a liquid storage cavity is formed in the side wall of the grinding box, a motor is fixedly arranged on the side wall of the grinding box, an output shaft of the motor extends into the grinding box, chucks are arranged at the tail end of an output shaft of the motor and the inner wall,right opposite to the output shaft of the motor, of the grinding box, and reciprocating lead screws are rotationally connected between the inner walls, located above and below the chucks, of the grinding box. According to the device, through the arrangement of a driving mechanism, a liquid pumping mechanism, an elastic film, a through hole and a liquid outlet hole, a grinding ring horizontally moves in a reciprocating manner, and a roller rotates so that the surface of the roller can be stably and evenly ground, and the coaxiality precision and the surface smoothness of the roller are improved; and cooling liquid can be automatically sprayed for cooling and heat dissipation, the spraying time is fixed, the manual control is not needed, the precision is high, and the cooling liquid can be recycled, so that the environment is protected, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of cold rolling mills, in particular to a roll surface treatment device for cold rolling mills. Background technique [0002] The cold rolling mill is a high-precision cold-rolling processing equipment for metal materials. The cold rolling mill is generally composed of a working mechanism and a transmission mechanism. The working mechanism includes a frame, rolls and roll bearings. After the rolls of the cold rolling mill are cast and formed, they generally need to be cut, thermally hardened, and polished before they can be installed on the cold rolling mill for use. A large part of the machining accuracy of the cold rolling mill depends on the surface finish of the roll and Coaxiality, so the later grinding of the roll is very important. [0003] The roll will generate a lot of heat during grinding. In order to prevent thermal deformation on the surface, it is necessary to dissipate heat and cool the roll ...

AI Technical Summary

Problems solved by technology

[0003] The roll will generate a lot of heat during grinding. In order to prevent thermal deformation on the surface, it is necessary to dissipate heat and cool the roll in time. The existing roll grinding device needs to manually open the switch to spray coolant to the roll during grinding. This method is not only relatively It is troublesome, labor-intensive, and it is difficult for the staff to properly grasp the timing of coolant injection, which is prone to mistakes; at the same time, the existing roll grinding device cannot collect and utilize the sprayed coolant, and the cooling consumed during grinding More liquid, higher cost
