[0002] Circular shears have excellent performance in many fields. In the construction industry, a large number of steel plates need to be accurately cut before they can be used to build bridges or make other building structures. In the automobile manufacturing industry, many parts such as car doors and frames also require steel plate materials, which also cannot be separated from the help of circular shears.

[0003] The existing device uses a rotating disc and blades fixed on the disc. The blades are usually arranged in a ring. As the disc rotates, the workpiece can be sheared continuously and evenly to ensure that the size of each steel plate meets the design requirements and is aligned for shearing.

[0004] There are concave and convex positions on the surface of the steel plate. During the shearing process, the concave and convex positions in the steel plate will affect the cutting position of the disc blade. The concave and convex positions or creases will cause the steel plate to shift and affect the size of the steel plate cutting. Summary of the invention

[0005] The purpose of the present invention is to provide a clamping and positioning structure for disc shearing and a method of using the same in order to solve the problem that depressions and protrusions in the steel plate will affect the cutting position of the disc blade during the shearing process, and the positions of the depressions and protrusions or creases will cause the steel plate to be displaced, affecting the size of the steel plate cut.

When the arc block moves downward to the bottom, the surface of the arc block will stop contacting the extrusion column, and the position of the No. 3 roller will be aligned with the position of the edge of the cut steel plate. Arc pipes are provided at both ends of the main body, and the sheared steel plate edge enters the interior of the arc pipe, so that the sheared steel plate edge is guided from the arc pipe into the external edge crushing machine for crushing and recovery, which is convenient for the recovery of the steel plate edge. An arc block is fixed at the end of the sliding rod, and a No. 2 fixing frame is fixed in the middle of the top of the main body, and extrusion columns are fixed at both ends of one side of the No. 2 fixing frame.
