Description

Technical Field

[0001] The utility model relates to a stamping die for a stamping part, belonging to the technical field of stamping dies. Background Art

[0002] A stamping die is a pressure processing structure that uses a die installed on a press to apply pressure to the stamped part, causing it to separate or plastically deform, thereby obtaining the required part. Stamping dies are widely used in the manufacturing industry, especially in the fields of automobiles, home appliances, construction, precision machinery, electronics, etc. For example, in automobile manufacturing, stamping dies are used to process metal shells such as car bodies, doors, hoods and trunks.

[0003] In existing stamping dies, the stamping head is often fixedly connected to the stamping die and is not easy to replace. After long-term use, the stamping head is prone to certain wear or mechanical failure, resulting in defective products when stamping parts, affecting the product qualification rate and possibly increasing production costs. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a stamping die for stamping parts, which has a stamping head that is easy and quick to disassemble and install.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] The top end face of said sliding column is fixed with a sliding sleeve on all sides, and a sliding column is movably installed in said sliding sleeve. A top plate is installed on the upper end surface of said sliding column, and a cylinder is installed on the upper part of said top plate. The bottom of said cylinder passes through said movable plate and is connected to a cylinder column. A bottom plate is installed on the lower end surface of said sliding column, and support legs are installed around the lower end surface of said bottom plate. A first limiting hole is symmetrically opened inside said movable plate, and two first limiting grooves are symmetrically opened on both sides of said first limiting hole, and a limiting block is installed inside said first limiting groove. A punching head is installed on the inner wall of said first limiting hole, and a second limiting groove is symmetrically opened on the outer wall of said punching head. A second limiting hole is opened inside said punching head, and a threaded groove is opened inside said second limiting hole. A support frame is installed on said movable plate, and a threaded hole with a bolt is opened on said support frame.

[0007] Furthermore, the limiting block is adapted to the second limiting groove, an end of the limiting block away from the punching head is fixedly connected to a spring, and an end of the limiting block close to the punching head is semicircular.

[0008] Furthermore, the bolt passes through the threaded hole and is threadedly connected to the second limiting hole.

[0009] Furthermore, two vertical plates are symmetrically installed between the top plate and the bottom plate, and a fan is installed between the two vertical plates.

[0010] Furthermore, a first slide groove is opened on one side surface of the vertical plate, and a slider adapted to the first slide groove is slidably installed on the side of the fan close to the vertical plate. A second electric telescopic rod is installed on the top of the base plate, and one end of the second electric telescopic rod is connected to the fan.

[0011] Furthermore, a first fixing plate is symmetrically installed on the upper end surface of the bottom plate, a first electric telescopic rod is installed on one side of the first fixing plate, and a push plate is fixedly connected to one side of the first electric telescopic rod.

[0012] Furthermore, a second slide groove is opened on the bottom plate, a support plate is installed on the top of the bottom plate, a rack is movably installed on the inner wall of the second slide groove, the rack is fixedly connected to the support plate, a gear is meshed and connected below the rack, and a round rod is installed on one side of the gear.

[0013] Furthermore, a second fixing plate is installed on the lower end surface of the bottom plate, a driving motor is installed on one side of the second fixing plate, and an output end of the driving motor is connected to the round rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] When the punch head needs to be installed, the punch head is lifted toward the first limit hole. During the lifting process, the limit block is squeezed and the spring is compressed inward until it is completely retracted into the first limit groove; when the punch head is lifted to a certain height, the limit block will automatically pop out and engage with the second limit groove in the punch head, and then the bolt is aligned with the threaded hole on the support frame and rotated downward to connect the bolt with the threaded groove in the second limit hole, so that the bolt and the punch head are connected to further fix the punch head; when the punch head needs to be disassembled, the bolt is first rotated to separate it from the second limit hole, and then the punch head is dragged downward to disengage the limit block from the second limit groove to complete the disassembly of the punch head; the detachable punch head can be more easily replaced or repaired in the event of failure or wear, which reduces downtime and improves the overall practicality and production efficiency of the equipment. By replacing worn parts rather than the entire equipment, the replacement cost can be significantly reduced and the service life of the overall equipment can be extended.
