Rolling Looper

Abstract

The invention discloses a roll steel loop. The roll steel loop comprises a rack, an air cylinder, a first connecting rod, a tension roller, a second connecting rod, a first air pressure damping cylinder, downward pressing transmission mechanisms and transmission mechanism supports, wherein one end of the air cylinder is hinged to the upper end of the rack, the other end of the air cylinder is hinged to one end of the first connecting rod, the other end of the first connecting rod is hinged to one end of the second connecting rod, the other end of the second connecting rod is hinged to one side face of the rack, the tension roller is horizontally arranged, one end of the tension roller is rotationally arranged on the hinge joint of the first connecting rod and the second connecting rod, the first air pressure damping cylinder is obliquely arranged on the upper side of the second connecting rod, one end of the first air pressure damping cylinder abuts against the second connecting rod so that the second connecting rod can be pressed downwards all the time, and the transmission mechanism supports are fixed to the two sides of the upper end of the rack. The roll steel loop is simple in structure, convenient to operate, accurate in tension control and good in effect.

Description

technical field [0001] The invention relates to a looper, in particular to a steel rolling looper. Background technique [0002] In the process of high-speed wire and bar production, because the second flow rate between the racks is not exactly the same, such a speed difference will cause tension or relaxation of the wire or bar between the two racks, whether it is The tension or relaxation of the wire or rod will form tension, which will affect the physical properties and other factors of the wire or rod during processing, resulting in a decline in product processing quality. Therefore, in order to obtain higher product quality, With the aid of the looper to adjust the rolling tension between the racks, the traditional looper directly drives the height of the looper through the cylinder to achieve tension adjustment. This driving method requires the cylinder to drive and adjust back and forth, but the adjustment error of the cylinder is relatively large, making it difficult...

AI Technical Summary

Problems solved by technology

The looper can add a finishing mill behind the steckel mill on the basis of the existing rolling line, reduce the number of rolling passes to increase production capacity, but it mainly relies on a hydraulic cylinder to drive back and forth, and its control accuracy is difficult to control. Pressure control accuracy is low
