Description

Technical Field

[0001] The utility model mainly relates to the field of metal punching equipment, in particular to a metal punching tool. Background Art

[0002] Metal pipes play a vital role in industrial production and construction due to their high strength, corrosion resistance, and durability. They not only serve as conduits for transporting liquids and gases, but are also widely used in a variety of fields, including building structures, machinery manufacturing, automobile manufacturing, and furniture production. Depending on the specific requirements, metal pipes can be customized through various processing methods. For example, in certain specific applications, such as ventilation systems, radiators, or decorative frames, it may be necessary to drill holes or cut notches in the metal pipes. In these cases, a dedicated punching machine can be used to accomplish this task. A punching machine is a mechanical device that can efficiently and accurately punch holes of the desired shape into sheets or pipes. It is usually suitable for mass production and occasions requiring higher precision, but general punching work is generally performed on the outside of metal pipes. Since the force area of the pipe is small after the punch contacts the outer wall of the pipe, it is easy to cause depression or convex deformation at the punching point, affecting product quality. In severe cases, the punched pipe will be deformed and scrapped. Therefore, there is no tooling device that can perform precise control to fix and adjust the pipe when performing fine punching on the pipe. Therefore, we propose a metal pipe punching tooling to solve this problem. Utility Model Content
