[CN201721018106.X] Strip steel guide device of plate shearing machine


[CN201721018106.X] Title of Strip Steel Guide Device for Plate Shearing Machine: Application Number of Strip Steel Guide Device for Plate Shearing Machine: CN201721018106.X Applicant: Shandong Shengli Steel Pipe Co., Ltd. Application Date: 2017-8-14 Patent Type: Utility Model The utility model is mainly used to guide strip steel into plate shearing machine, and relates to a strip steel guide device for plate shearing machine of spiral welded pipe production line, which includes a support and a roller, the idler is mounted on the idler shaft by bearings. The utility model adds a free-rotating roller to the traditional guide device, so that the friction between the strip steel and the guide device changes from sliding friction to rolling friction, which effectively avoids the problem of strip steel scratches and improves product quality; The height self-adjusting mechanism of the roller realizes the free adjustment of the upper movable seat and the height of the roller by adjusting the spring and the guide bolt, so as to effectively adapt to the up and down floating of the strip steel, finally, the impact of strip steel on the roller is effectively reduced, and the failure rate is reduced.
