Plate shearer capable of positioning plates accurately

Abstract

The invention discloses a plate shearer capable of positioning plates accurately. The plate shearer comprises a machine body (1), a working table (2) and a plate shearing blade (3) capable of making reciprocating motions vertically along the machine body (1), wherein the moving direction of the plate shearing blade (3) is perpendicular to a table board of the working table (2), a shearing structure is formed by the plate shearing blade (3) and the edge of the working table (2), a boss (4) perpendicular to the table board of the working table (2) is arranged on the working table (2), the boss (4) is perpendicular to the plate shearing blade (3), a cylinder I (5) parallel to the boss (4) is mounted on the table board of the working table (2), an electromagnetic valve is mounted on the cylinder I (5), and a displacement sensor is mounted on a piston rod of the cylinder I (5). The plate shearer further comprises a PLC, and the electromagnetic valve and the displacement sensor are both connected with the PLC. The plate shearer has the advantages that line marking is not needed, the automation degree is high, operation is easy, and the plates can be positioned accurately.

Description

technical field [0001] The invention relates to the technical field of plate blanking and shearing, in particular to a plate shearing machine with precise positioning of the plate. Background technique [0002] The shearing machine is a mechanical device used for punching and shearing the sheet metal. By means of the upper blade and the fixed lower blade installed on the machine bed, a reasonable blade gap is used to apply shearing force to metal sheets of various thicknesses. , so that the plate is broken and separated according to the required size to obtain a blank with straight edges. After the blank is finished by mechanical equipment, it can be used to produce auto parts. [0003] At present, in the production process, when using a shearing machine to punch and shear a sheet according to a given size requirement, it is necessary to use a measuring tool to measure the required size, mark it manually, and then use the shearing machine according to the given size requirem...

Problems solved by technology

[0003] At present, in the production process, when using a shearing machine to punch and shear a sheet according to a given size requirement, it is necessary to use a measuring tool to measure the required size, mark it manually, and then use the shearing machine according to the given size requirements. Punching and shearing at the scribed position, the operation process is more complicated, which is not conducive to the improvement of production efficiency, and the manual scribing mark has errors every time, resulting in blanking errors, it is difficult to ensure the cutting accuracy of the cut blank, and there is a problem of positioning Disadvantages of poor precision

Manual marking also greatly increases the workload of workers, seriously affects production efficiency, and ultimately leads to low production output
