A straightening and threading equipment for steel strip rolling

Abstract

The invention relates to the field of steel strip rolling, in particular to a straightening and stripping device used for steel strip rolling, comprising an uncoiler, a steel coil and a straightening machine. On the side of the machine, the straightening machine includes a drive frame, a hot pressing mechanism, a guide roller and a bottom plate. There are roller seats on both sides of the guide roller, and each roller seat is fixedly installed on the top of the bottom plate through a square tube. An air-cooling mechanism is fixed on the pressing mechanism, and a pressing mechanism is fixed on the side of the hot-pressing mechanism away from the driving frame. It is induced by the induction mechanism, and then the steel coil is hot-pressed by the hot-pressing mechanism to ensure that the head of the steel coil forms the required angle. The process is simple, easy to operate, and improves the production efficiency of workers. Straightening work, which requires constant human control, reduces a lot of work hours for workers.

Description

technical field [0001] The invention relates to the field of steel strip rolling, in particular to a straightening and stripping device used for steel strip rolling. Background technique [0002] Straightening machine is a device for straightening metal profiles, bars, pipes, wires, etc. The straightening machine uses the straightening roller to extrude the bar to change the straightness, but when straightening the steel coil, it is difficult to straighten the required lead according to the required lead angle. [0003] Chinese patent application number: CN201811176420.X; discloses a head straightening method, the method provided by the present invention can realize head straightening and threading based on the structure of the rolling mill itself, without additional straightening equipment, thereby simplifying the equipment on the one hand scale, while also avoiding the loss of production efficiency due to straightening equipment. [0004] This scheme has the following di...

AI Technical Summary

Problems solved by technology

[0005] 1. This solution can straighten the tape head and ensure that the tape head of the steel coil forms a certain angle, but because the roller is pressed back and forth to ensure the required shape, this process is too cumbersome and complicated, which reduces the number of workers. production efficiency

[0006] 2. This solution can straighten the lead, but in the process of straightening the lead, it is necessary to continuously control the straightening of the lead, which wastes a lot of working time of the workers
