A tension roller grinding device

Abstract

The invention relates to the field of reeling machine tension roller treatment tools, in particular to a tension roller grinding device. The device comprises a lower support, a sliding rail, a trolley, a sliding rail walking drive mechanism and a trolley walking drive mechanism. The sliding rail is arranged on the lower surface of the lower support and walks on the lower support. The trolley is arranged on the sliding rail and provided with millstone and walks on a track on the sliding rail. The sliding rail walking drive mechanism is arranged on the lower support and drives the sliding rail installed on the lower support to walk. The trolley walking drive mechanism is installed on the sliding rail and connected with the trolley through a lead screw, and the trolley is driven to walk on the track. When rollers are produced and replaced or rolling must be stopped to treat concave-convex marks, manual operation can be replaced to rapidly and automatically grind the tension rollers, labor intensity is lowered, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the field of tension roller processing tools for coilers, specifically a tension roller grinding device. Background technique [0002] Due to the inevitable friction between the hot-rolled strip and the side guide plate of the coiler during the normal production process, the scraped iron filings are brought in; the tail flick that occurs during the strip rolling process; the biting impact of the strip head Both can cause foreign matter to adhere to the surface of the tension roller and cause pit-like printing quality defects on the surface of the strip. [0003] The existing grinding method is to rely on the operator to manually grind with a grindstone, and the manual online grinding of the tension roller has the following disadvantages: [0004] 1) The security is not high. Personnel are required to enter the equipment during online grinding. It can be seen that the internal space of the tension roller is too narrow, and the...

AI Technical Summary

Problems solved by technology

[0004] 1) The security is not high

Personnel are required to enter the equipment during online grinding. It can be seen that the internal space of the tension roller is too narrow, and the safety cannot be effectively guaranteed when grinding in a narrow space.

[0005] 2) The work is intense and time-consuming

Due to working in a narrow and confined space, the efficiency of manual grinding is not high, and sometimes it needs to be repeated

[0006] 3) Insufficient grinding precision

Grinding with grinding stones manually, on the one hand, the grinding of the roller surface is uneven, and the grinding accuracy cannot be effectively guaranteed, so that the elimination of product defects cannot be guaranteed

On the other hand, the service life of the tension roller is reduced, and the consumption of grinding stone is large, resulting in an increase in production cost

[0007] 4) Due to the high rigidity of the connection between the secondary heat and continuous casting, the flexibility of production coordination is poor, and the manual grinding of the tension roll needs to be stopped for cooperation. After recovery, the stop of rolling will cause damage to the process stability, which will have a negative impact on production continuity and product quality very big
