Description

Technical Field

[0001] The utility model relates to the technical field of punch assembly machines, and specifically relates to a punch blanking mechanism for a punch assembly machine. Background Technique

[0002] Punches are essential accessories in stamping dies and are widely used in fields such as metal stamping, plastic processing, and automobile manufacturing. In stamping operations, punches play key processing roles such as shearing, punching, and forming of metal materials. Due to their high strength, high wear resistance, and corrosion resistance, punches have become indispensable tools in many machining processes.

[0003] During the processing of punches, tiny burrs or sharp edges often inevitably remain on the surface of the punches. To ensure the normal use of the punches, production enterprises usually arrange specialized grinders after the punches are processed, which not only increases the production cycle but also increases the work pressure of the staff. Therefore, it is necessary to immediately perform preliminary grinding treatment on the surface of the punches when they are cut from the raw materials to remove burrs and edges, so that the punches already have high surface quality when they leave the production line, thereby reducing the work pressure of the staff. Content of the Utility Model

[0004] The purpose of the utility model is to provide a punch blanking mechanism for a punch assembly machine to solve the problems raised in the above background technique.
