Description

Technical Field

[0001] The utility model relates to the technical field of punching machines, in particular to a novel punching mechanism of a punching machine. Background Art

[0002] A punch press is a stamping press. In national production, the stamping process has the advantages of saving materials and energy, high efficiency, low technical requirements for operators, and the ability to make products that cannot be achieved by mechanical processing through various mold applications. Therefore, its use is becoming more and more extensive. The punching mechanism of the punch press is an important component of the punch press. Its main function is to punch out the required holes according to the size of the holes required by the workpiece.

[0003] A Chinese patent with publication number CN216175770U was searched and disclosed a new punching mechanism of a punch press.

[0004] The above technical solution includes: an operating table, a die, a punch, a fixing mechanism, a positioning mechanism and a debris collection mechanism; the surface of the operating table is fixedly connected to the die through a fixing mechanism, and the side of the operating table away from the die is fixedly connected to a debris collection mechanism; the debris collection mechanism includes a collection bucket, a debris box and a fan; a collection bucket is provided inside the operating table, and the collection bucket is covered by the die, and the end of the operating table away from the die is fixedly connected to a debris box, and the debris box is connected to the collection bucket, and an air extraction chamber is provided on the side wall of the collection bucket, and a fan is fixedly connected to the air extraction chamber, and a vertical filter is fixedly connected to the connection between the air extraction chamber and the debris box. This device uses negative pressure to fix the workpiece and collect debris, and automatically releases the constraints after the punching is completed, and does not require unnecessary fixing and disassembly operations, so it is very convenient to use;

[0005] However, in the above scheme, during the punching operation, the force generated by the punching is concentrated on the punch and the impact column, and the connection structure between the punch and the impact column is relatively simple, which may easily cause damage to the punch and the impact column during continuous punching operations, affecting the use of the equipment; this technology uses wind pressure to recycle the debris generated by punching, but most of the punching debris is circular with a large area and can naturally fall into the debris box, and the through hole is directly connected to the debris box, so it can fall into the debris box without wind pressure, and the large opening of the collection bucket reduces the contact area between the template and the workbench, increases the pressure between the template and the workbench, and easily causes permanent damage to the template or the workbench.

[0006] Therefore, we propose a new punching mechanism for a punch press. Utility Model Content
