[0003] In order to prevent debris from splashing out during the stamping process, the existing copper cap stamping forming device generally adopts a closed container. During use, it is not convenient to automatically take out the stamping die and the formed copper cap. At the same time, it is not convenient to install and fix bottom molds of different sizes when copper caps of different sizes need to be made, which reduces the use efficiency.

[0004] For example (authorization announcement number CN220072935U) a fuse copper cap stamping device, through the design of the support column, support plate and lifting plate, the support column supports the support plate to prevent the support plate from falling, and can also stabilize the lifting plate to prevent the lifting plate from offsetting when moving up and down, resulting in stamping failure, affecting the stamping quality, improving the product yield, and improving the stamping quality; the stamping ring is engaged with the stamping head, and the protective ring is engaged with the stamping ring and the stamping groove, which can effectively avoid the stamping head and the stamping ring from being misaligned, resulting in stamping failure, affecting the stamping quality, and at the same time, the vibration generated during stamping is reduced by the buffer plate and the shock absorber, preventing the stamping head and the base from vibrating, resulting in stamping errors, affecting the stamping quality, and improving the service life of the stamping forming device and the stamping quality. The device has this problem: during use, it is not convenient to automatically remove the bottom molds of different sizes and the copper caps that have been stamped, which reduces the use efficiency.

[0007] The output ends of the two second motors are connected to two clamping frames through bidirectional screw rods, vertical plates are installed on the vertical sides of the two clamping frames, push rods are installed on the vertical inner walls of the multiple clamping frames, and clamping plates for fixing the fixed mold are installed on one side of the moving parts of the multiple push rods.

[0008] In a further embodiment, two slots are provided at the top of the bottom frame, and the inner walls of the two slots are closely attached to the installation frame.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0015] During use, the copper cap stamping and forming device pushes the top plate and the movable die for stamping through a cylinder arranged at the top end of the connecting column, so that the plug plate at the bottom end of the top plate can be inserted into the installation frame during the downward movement. Under the action of the push rod at the bottom end of the connecting frame, the installation frame is moved up and down by the movable plate, so that the spring damper in the installation frame has a buffering effect, preventing the movable die and the fixed die of different sizes from vibrating and causing errors in the stamping process, thereby increasing the service life of the stamping and forming device and improving the stamping quality.

After the stamping is completed, the connecting frame 11 arranged in the bottom frame 9 is used to move the connecting frame 11. 7. The moving block 16 arranged in the connecting frame 17 is displaced by the driving of the first motor 19, thereby driving the moving frame 11 to be limited by the limiting groove 24 on the limiting plate 12, so that the moving frame 11 is separated from the protective state of the connecting box 5, and the fixed mold 8 arranged in the moving frame 11 is exposed to the outside; then the second motor 25 arranged in the groove is used to drive the two clamping frames 20 on the outer periphery of the bidirectional screw to displace toward each other, so that the distance between the vertical plates 21 on both sides is expanded, and the fixation of the fixed mold 8 is loosened.

[0032] The spring damper 14 is a mechanical device mainly used for shock absorption and buffering. It consists of two parts, a spring and a damper, and its working principle is to absorb impact force and reduce vibration through the elastic deformation of the spring and the resistance of the damper. The working principle of the spring damper 14 can be divided into two processes: the elastic process and the damping process. In the elastic process, when a force is applied to the spring by the outside world, the spring will deform and store energy. In the damping process, when the spring returns to its original state, the damper will prevent the rebound movement of the spring and consume the stored energy. The main function of the spring is to absorb impact force and store energy, and its elastic coefficient and the shape of the spring directly affect the performance of the spring damper 14. The main function of the damper is to consume the kinetic energy of the spring, reduce impact force and vibration, and the damper is usually generated by friction resistance or liquid resistance.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
