Automatic assembly and disassembly system and method for roller ring set of finishing mill group

Abstract

The invention discloses an automatic assembly and disassembly system and method for roller ring sets of a finishing mill group, and belongs to the field of metal machining, the automatic assembly and disassembly system comprises a sliding seat and the finishing mill group, a plurality of roller ring sets are arranged on the finishing mill group, a robot is arranged on the sliding seat, and a clamping device and a positioning mechanism are arranged on a swing arm of the robot; the clamping device comprises a rotary table which is rotationally arranged, a first clamp, a second clamp and a third clamp which can be used for clamping, assembling and disassembling tools are arranged on the rotary table, and the first clamp, the second clamp and the third clamp are located on stations on the rotary table respectively; by using the robot, the parts of all the parts of the roller ring set can be rapidly disassembled and assembled, the robot achieves automatic operation in the whole process, the disassembled and assembled parts and positions can be actively recognized, installation tools can be automatically selected, manual participation is reduced, the cost is saved, and the operation risk in the disassembling and assembling process is reduced.

Description

technical field [0001] The invention belongs to the field of metal processing, in particular to an automatic assembly and disassembly system and method for roll ring groups of a finishing mill. Background technique [0002] The rolling production of coils in steel mills and high-end wire factories is carried out continuously for 24 hours. Under the action of long-term high-speed movement of high-temperature wire rods, the roll rings will gradually wear out, reduce rolling precision, and then affect the quality of coiled products. Therefore It is necessary to replace the roll rings from time to time to ensure that the production process requirements of the entire rolling line are met. [0003] The original roll ring assembly and disassembly are all manual operations. The specific structure of the roll ring set includes top bolts, protective covers, round nuts, and roll rings arranged from top to bottom. There is a risk to the safety of personnel when driving in conjunction w...

AI Technical Summary

Problems solved by technology

[0005] 1. The disassembly and assembly of the roll ring group is currently a manual operation, which requires 4-6 people to operate at the same time. At present, the labor cost is getting higher and higher, and it is difficult to find people for positions with high labor intensity;

[0006] 2. The protective cover, roll ring and hydraulic tools are all heavy, the heaviest is more than 30kg, and the manual work is labor-intensive;

[0007] 3. The manual assembly and disassembly of the roll ring group requires driving to participate in the operation, which poses a safety risk to personnel
