Flattening device for winding and working method thereof

Abstract

The flattening device for winding is arranged on the feeding side of a winding machine and comprises a rotating shaft, the two ends of the rotating shaft are horizontally erected on a rack of the winding machine, the inner side of the rotating shaft is rotationally connected with a rotating arm, the rotating arm is in an L shape, the driving end of the rotating arm is connected with a first acting cylinder through a pin shaft, and the first acting cylinder is installed on the rack of the winding machine through a first cylinder support; the working end of the rotating arm is fixedly connected with a working short arm, and the working short arm is connected with the working end of the rotating arm at an obtuse angle; the front end of the working short arm is provided with a flattening roller used for pressing and rolling a metal thin strip, the two ends of the flattening roller are erected in a square box installed at the front end of the working short arm through a flattening roller end base, the top of the flattening roller end base is provided with an elastic pressing assembly, and a guide assembly is arranged in front of the flattening roller end base. And the elastic pressing assembly downwards pushes the flattening roller end seat along the guide assembly. According to the flattening device for winding and the working method of the flattening device, the flattening roller is elastically pressed, the adaptability to the shape of a strip coil is high, continuous and stable flattening force is provided, and the winding quality is improved.

Description

technical field [0001] The invention relates to the technical field of coiling of metal strip rolling lines, in particular to a flattening device for coiling and a working method thereof. Background technique [0002] The coiler is used in the rewinding part of the strip processing production line, and the strip is mechanically wound into coils, which is widely used in the metal strip rolling production line. For the winding of aluminum strips, hydraulic or electric winding machines are often used for winding. Most of the existing winders are not equipped with a flattening device, or are equipped with a simple flattening roller to compress the rewinding aluminum strip, which cannot well ensure that the winding is dense, there are no air bubbles between layers, and the end faces are neat. Moreover, the simple flattening roller does not have the ability to quickly adjust when the coil profile is beating, especially in the case where the shape of the coil formed by winding is ...

AI Technical Summary

Problems solved by technology

Most of the existing winders are not equipped with a flattening device, or are equipped with a simple flattening roller to compress the winding aluminum strip, which cannot better ensure that the winding is compact, there is no air bubble between the layers, and the end surface is neat

Moreover, the simple flattening roller does not have the ability to quickly adjust the coil profile when it jumps, especially when the shape of the coil formed by winding is elliptical, which will cause the flattening force of the flattening roller to be discontinuous. It is easy to have interlayer bubbles and uneven end faces
