Automatic roll dismounting tool for roll collar of rolling mill and roll collar dismounting method

Abstract

The invention discloses an automatic roll dismounting tool for a roll collar of a rolling mill and a roll collar dismounting method The automatic roll dismounting tool comprises a cylinder body (1), wherein the cylinder body (1) is connected with a supporting rod assembly (3) and a sliding rail and sliding block combination (5); a hydraulic roll dismounting tool (4) mounted in the cylinder body (1), wherein the hydraulic roll dismounting tool (4) and the clamping edge of a taper sleeve (7) are clamped together; and a group of clamping mechanisms (2) fixed to the lower end of the cylinder body (1) and used for clamping the roll collar (6). The automatic roll dismounting tool and the roll collar dismounting method are mainly used for automatically disassembling the taper sleeve / roll collar of a roll collar assembly of the rolling mill, can be combined with a mechanical arm to realize automation of the roll disassembling process, are simple and reliable in structure, shorten the operation process and reduce the labor intensity of operators.

Description

technical field [0001] The invention relates to a rolling mill roll ring automatic roll removal tool and a roll ring removal method. Background technique [0002] The ring assembly is mounted on the mill spindle to extrude the wire / rod to the desired dimensions. The accuracy of the roll ring is related to the quality of the product, so the roll ring needs to be replaced in time due to the wear of the roll ring after rolling for a certain period of time (the replacement frequency of the roll ring is related to the amount of steel passed). The roller ring assembly is mainly divided into a protective cap, a cone sleeve, and a roller ring body. The taper sleeve is located between the main shaft of the rolling mill and the roll ring, and the roll ring is tightened and fixed by cooperating with the tapered surface of the main shaft of the rolling mill. The outer end of the taper sleeve is equipped with a nut and the main shaft is threaded. The protective cap is installed outside...

AI Technical Summary

Problems solved by technology

The roller ring needs to be replaced and maintained frequently. The current manual disassembly of the roller ring involves repetitive labor, high labor intensity, long replacement time and low efficiency, high temperature working environment, and danger-prone situations.
