Description

Technical Field

[0001] The utility model relates to the technical field of automatic punching machines, and more specifically to a punching mechanism of an automatic punching machine for metal materials. 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 produce products that cannot be produced by mechanical processing through various mold applications. Therefore, its use is becoming more and more extensive. Stamping production is mainly for sheet metal. Through the mold, blanking, punching, forming, drawing, trimming, fine blanking, shaping, riveting and extrusion can be made, which are widely used in various fields.

[0003] In order to improve the efficiency and continuity of stamping, automatic stamping machines have emerged, which enable the stamping machine and the manipulator to cooperate with each other to continuously stamp a product. However, the stamping head of the existing stamping machine cannot protect the outside of the parts when stamping, and there is a risk of splashing when the product is stamped. In addition, the stamping machine makes a lot of noise during stamping, which affects the surrounding environment. For this reason, we propose a stamping mechanism for an automatic stamping machine for metal materials. Utility Model Content
