The rotating table 20 0 is provided with a fixed platform 202 at the upper end, the axis of the fixed platform 202 coincides with the axis of the rotating platform 200, the upper edge of the fixed platform 202 is slidably connected to a sliding rod 203 near each bottom mold 201, the upper edge of the fixed platform 202 is provided near each bottom mold 201 for providing sliding support for the sliding rod 203, the rod body of the sliding rod 203 is rectangular, and the upper end thereof is a circular plate body, and the lower end of the sliding rod 203 is provided with a sliding groove connected to each bottom mold 201. 01 is equipped with a stamping die head 204, a spring 205 is arranged between the top of the sliding rod 203 and the fixed platform 202, and the spring 205 is respectively movably sleeved on the outside of the sliding rod 203 adjacent to the same side, and a driving component for driving the rotating platform 200 to rotate is also arranged at the lower end of the top plate 207, and a material discharge component is also arranged on the fixed platform 202. The adjustment mechanism also includes a slide groove 206 respectively arranged in the bottom mold 201, and the slide groove 206 is slidably connected with the top plate 207. The diameter of the upper end of the top plate 207 is larger than the diameter of the lower end thereof, and a spring 208 is provided between the lower end of the top plate 207 and the slide groove 206 in which it is located. The adjustment mechanism also includes receiving grooves 209 respectively arranged at the bottom of the mold cavity of the bottom mold 201, and the receiving grooves 209 respectively cooperate with the upper parts of the top plates 207 adjacent to the same side, and the bottom of the mold cavity of the bottom mold 201 fits with the upper end of the top plate 207, and the plane formed by the top plate 207 and the receiving grooves 209 after being embedded constitutes the bottom of the mold cavity of the bottom mold 201.

[0026] When it is necessary to switch the stamping specifications of the aluminum cover, the driving assembly drives the rotating table 200 and its auxiliary mechanisms to rotate synchronously, so that the bottom mold 201 and the stamping die head 204 of the corresponding specifications are accurately moved to the position directly below the stamping head of the punch press 100. The multi-station design of the rotating table 200 can realize the rapid switching of the bottom mold 201 and the stamping die head 204 of different specifications, and can adapt to the production of various specifications without long-term shutdown to replace the mold, which significantly improves the processing continuity and equipment utilization rate.

[0028] The motor 303 is started, and its output shaft rotates to drive the worm 302 to rotate synchronously. The worm 302 drives the rotating table 200 and its auxiliary mechanisms to rotate synchronously through the worm wheel 301 meshing with it, so that the base die 201 and the punch die head 204 of corresponding specifications are accurately moved to the position directly below the punch head of the punch press 100, which not only plays a rapid driving role, but also can utilize the self-locking characteristics of the meshing of the worm 302 and the worm wheel 301 to ensure the stability of the rotating table 200.

The guide assembly also includes fixed cylinders 502 respectively arranged on both sides of the guide plate 500, the fixed cylinders 502 are rectangular fixed cylinders, and guide rods 503 are slidably connected in the fixed cylinders 502, and the guide rods 503 are rectangular guide rods. The inner ends of the guide rods 503 are respectively fixedly connected to the adjacent guide plates 501 on the same side, and the outer ends of the fixed cylinders 502 are rotatably connected to the screw rods 504. The outer ends of the fixed cylinders 502 are provided with rotating holes for providing rotation support for the screw rods 504, and the screw rods 504 are respectively threadedly connected to the thread holes set on the adjacent guide rods 503 on the same side.

[0032] The blown-off formed aluminum cover falls on the guide plate 500, and the guide plate 501 can adjust the extension length of the guide rod 503 through the screw 504 to guide the aluminum cover to slide out along the set path.

[0036] The working principle of the aluminum-plastic composite cover stamping device provided by the present invention is as follows: first, the connecting pipe 403 is connected to the air outlet end of the external air source. When the stamping specifications of the aluminum cover need to be switched, the motor 303 is started, and its output shaft rotates to drive the worm 302 to rotate synchronously, and the worm 302 drives the rotating table 200 and its auxiliary mechanisms to rotate synchronously through the worm gear 301 meshing with it, so that the bottom mold 201 and the stamping die head 204 of the corresponding specifications are accurately moved to the position directly below the stamping head of the punch press 100, and then the stamping speed of the punch press 100 is adjusted. The head moves downward, so that the limiting protrusion 600 on it cooperates with the limiting groove 601 on the top of the sliding rod 203 to ensure the stability and accuracy of the stamping process. The multi-station design of the rotating table 200 realizes the rapid switching of the bottom mold 201 and the stamping die head 204 of different specifications, and can adapt to the production of various specifications without long-term shutdown to replace the mold, which significantly improves the processing continuity and equipment utilization rate. Then the external conveyor drives the aluminum sheet to move, and the punching machine 100 is started at the same time. The punching head moves downward to push the sliding rod 203 and the stamping die head 204 to overcome the elastic The spring 205 moves downward, so that the stamping die 204 and the bottom die 201 are closed to complete the stamping of the aluminum cover. In this process, the top plate 207 is simultaneously subjected to pressure and overcomes the elastic force of the spring 208 to move downward, and finally embeds into the receiving groove 209 to avoid any interference with the aluminum cover forming operation. After one stamping is completed, the stamping head on the punch press 100 is reset, and the sliding rod 203 and the stamping die 204 are synchronously moved downward under the action of the rebound force of the spring 205. At this time, the top plate 207 is subjected to the pre-tightening force of the spring 208 to press the stamping die 204. The part is ejected from the mold cavity. At the same time, the corresponding solenoid valve 402 is opened to control the nozzle 401 to spray air to blow the formed aluminum cover away from the bottom mold 201. The blown-away formed aluminum cover falls on the guide plate 500, and the guide plate 501 adjusts the extension length of the guide rod 503 through the screw 504 to guide the aluminum cover to slide out along the set path. This design of automated unloading and guided transportation not only greatly improves production efficiency, but also effectively reduces manual intervention and labor intensity, while ensuring the consistency of product quality, providing reliable guarantee for large-scale production.
