Description

Technical Field

[0001] The utility model relates to the technical field of plate shearing machines, and more specifically to a metal plate positioning device of a plate shearing machine. Background Art

[0002] A shearing machine is a machine that uses one blade to make reciprocating linear motion relative to another blade to shear plates. It is based on a moving upper blade and a fixed lower blade, and adopts a reasonable blade gap to apply shearing force to metal plates of various thicknesses, so that the plates are broken and separated according to the required size. The metal plates need to be fixed when the shearing machine is running.

[0003] After searching, the utility model patent with announcement number CN216758390U discloses a metal plate positioning device for a shearing machine, including a machine body, a cutting tool is movably connected inside the machine body, a fixed block is fixedly connected to the left side of the cutting tool, a mounting block is movably connected inside the fixed block, a fixed slot is opened on the top of the mounting block, a fixing mechanism extending to the inside of the fixed slot is inserted on the top of the fixed block, and a connecting cross bar is fixedly connected to the bottom of the mounting block; the metal plate positioning device for the shearing machine, when the machine body drives the cutting tool to perform cutting operation, the cutting tool drives the fixed block to move up and down, and the fixed block drives the connecting cross bar, the mounting vertical block and the pressing block to move downward through the mounting block, during which the pressing block contacts the metal plate, and at this time the connecting spring is compressed to provide elastic force to make the pressing block contact with the metal plate more closely, so that the position of the metal plate is relatively fixed under the action of pressure. However, the above patent has the following shortcomings: the spring force is used to drive the pressing block to squeeze and fix the metal plate, and there is a risk of the spring expanding and contracting when shearing; and only one side of the shearing part of the shearing machine is fixed, and the other side is not fixed, so the positioning effect is poor. For this reason, we propose a metal plate positioning device for a shearing machine. Utility Model Content
