[0016] The technical scheme in the embodiment of the utility model will be clearly and completely described, obviously, the described embodiment is only a part of the embodiment of the utility model, not all embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skilled person in the art without making creative labor belong to the scope of the utility model protection.

[0017] Please refer to Figs. 1-3 , the utility model embodiment includes:

[0018] A punch mechanism for stamping die can be installed on different punch machines, and the structure includes: punch body 1, punch sheath 2, profiling connection slot 3, stop pin 4, punch clamp plate 5, installation groove 6, limit groove 7, punch backing plate 8.

[0019] The profiled connecting slot is arranged axially in the punch sheath and penetrates the upper and lower surfaces of the punch sheath, and the upper part of the punch body is inserted into the profiled connecting slot, so that the punch sheath increases the pressure resistance of the punch body, prevents the punch body from being deformed or broken due to large stress or being too long, and prolongs the service life of the punch body.

[0020] Further preferably, the punch body and the punch sheath are detachably connected, so that different punch sheaths can be selected according to the shape and length of the punch body.

[0021] The punch clamping plate is provided with a mounting groove, and limiting grooves are arranged on the punch clamping plate on both sides of the mounting groove and are in communication with the mounting groove, so as to facilitate the taking and placing of the punch sheath. The upper part of the punch sheath is movably arranged in the mounting groove, and a stop pin is arranged on each side of the punch sheath in the mounting groove and is movably connected with the limiting groove, so as to prevent the punch sheath from being pulled out of the punch clamping plate and improve the accuracy and stability of the connection between the punch clamping plate and the punch sheath. The punch clamping plate and / or the punch backing plate are connected with the upper die plate, so as to facilitate the replacement and maintenance of the punch.

[0022] In some embodiments of the present application, the punch clamping plate can be connected with the bottom surface of the upper die plate (group), and the upper die plate is provided with a through hole allowing the punch backing plate to pass through. When the punch body needs to be replaced, the punch backing plate can be directly disassembled from the top of the upper die plate, and then the punch sheath and the punch body are taken out, and then the new punch sheath and the punch body are inserted into the mounting groove of the punch clamping plate, without the need to disassemble the entire upper die group, thereby improving the convenience of disassembly.

[0023] Further preferably, the mounting groove and the punch sheath are provided with limiting guide surfaces 9 that are movably connected with each other, which not only can remind the installation direction, but also can improve the accuracy of the connection.

[0024] The punch backing plate is movably connected with the punch clamping plate by means of screws or other fasteners, and the side wall of the punch backing plate abuts against the end surface of the punch sheath and / or the punch body, so as to press the punch sheath and the punch body, prevent them from shaking or moving during punching, improve the accuracy and effectiveness of the punching, and close the opening of the mounting groove to prevent dust and debris from entering.

[0025] The punch mechanism for the stamping die has the advantages that the punch body is strengthened and protected by the punch sheath, the strength of the punch is improved, and the service life of the punch is prolonged. Different punches can be selected or replaced according to different use requirements through the cooperation of the punch sheath, the punch clamping plate and the punch backing plate, the flexibility of the punch mechanism is improved, the punch body can be quickly disassembled, the structure is simple, and the use is convenient.

[0026] The above merely illustrates the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, are all included in the patent protection scope of the present application.
