Five-roll tensioner

Abstract

The invention relates to a five-roll tensioner for the continuous cold tandem rolling of medium / narrow plain carbon steel bands continuous cold tandem rolling. The tensioner comprises that: an oil cylinder seat and a wallboard are fixedly arranged on a frame; an oil cylinder is arranged on the oil cylinder seat; the tail end of the oil cylinder is hinged on the oil cylinder seat through a pin; the end of a piston rod of the oil cylinder is fixedly connected with an upper roll seat; upper rolls are rotatably arranged on the upper roll seat; a track groove is fixedly arranged on the wallboard; the upper rolls are stuck in the track groove; a lower roll seat is fixedly arranged on the wallboard below the upper roll seat; lower rolls are rotatably arranged on the lower roll seat; the upper rolls are parallel to the axis of the lower rolls; the number of the upper rolls is one less than that of the lower rolls; and in the movement direction of the oil cylinder, every upper roll is positioned between two adjacent lower rolls. The tensioner not only can straighten band material in the steel band-rolling process so as to provide convenience for passing bands and avoid the disadvantages of high labor intensity and long auxiliary time in the prior art, but also can provide back tension required by rolling so as to guarantee product quality.

Description

technical field [0001] The invention relates to a five-roller tension machine for continuous cold rolling of medium and narrow common carbon steel strips. Background technique [0002] At present, there is usually no such five-high tension machine in the widely used cold continuous rolling mills for medium and narrow strips of ordinary carbon steel. In the process, it is time-consuming and labor-intensive, a lot of time is wasted, the labor intensity is enhanced, and the efficiency of the cold rolling mill is greatly reduced; at the same time, in the continuous rolling process, there is no back tension, and the quality of the rolled product is unstable. Good time difference, difficult to control the quality, reducing the benefits of the enterprise. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a machine that overcomes the shortcomings of the original mechanical labor intensity, long thr...
