Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a replaceable punching tool. Background Technology

[0002] In recent years, China's automotive industry has developed rapidly, with output increasing year after year. Improving production efficiency has become increasingly important. In the automotive interior industry, many products require water jet cutting to remove holes. However, for many small holes or relatively dense holes, water jet cutting is inefficient and wastes production capacity. Water jet cutting has the above problems, which greatly wastes production time and reduces production efficiency. Punching fixtures are a type of equipment used to cut materials. They are mainly used to punch materials according to preset shapes or sizes. This type of fixture is simple and practical in design and can efficiently complete cutting tasks. Using interchangeable punching fixtures, some complex and dense holes can be removed on the fixture, greatly reducing water jet cutting time.

[0003] For example, patent number (CN219633996U) discloses a punching tool, including a punching blade and a control box for controlling the punching blade to punch the sealing strip. It also includes a mounting box for placing on the ground. A frame is fixed to the upward-facing side of the mounting box. A punching cylinder for controlling the up-and-down movement of the punching blade is longitudinally provided on the frame, and the telescopic end of the punching cylinder extends below the frame. A connecting column is provided on the telescopic end of the punching cylinder. The punching blade is located on the end of the connecting column away from the punching cylinder. A punching table is provided on the side of the mounting box below the punching blade. By providing a protective frame and punching holes opened on the protective frame, the punching holes do not affect the punching blade's punching of the sealing strip. The protective frame can, to a certain extent, limit the position where the worker's hands are placed, i.e., the pressing position, so that the worker's hands are not injured by the punching blade.

[0004] Currently, due to certain limitations in the punching processing structure, punching fixtures are difficult to adjust flexibly according to processing needs, resulting in relatively limited punching products and hindering the expansion of the applicability of punching fixtures.

[0005] Therefore, since the aforementioned punching fixtures are difficult to adjust flexibly according to processing requirements, resulting in relatively limited punching products and hindering the expansion of the applicability of the punching fixtures, a modular punching fixture that allows for easy replacement of punching modules can be designed.
