[0032] Working principle: When working, the mold is placed in the fixed groove 111 according to production needs, and the plate is placed on the top of the workbench 106 and then the device is started. After the plate is placed on the top of the workbench 106, it will come into contact with the top plate 110 and squeeze the top plate 110. When the top plate 110 is squeezed, the pressure will be transmitted to the spring 108 and the first telescopic rod 109 and put them in a compressed state. When the spring 108 is compressed, the elastic potential energy will be released and a reaction force will be applied to the top plate 110. After the device is started, the first hydraulic cylinder 102 will be driven to start running. The first hydraulic cylinder 102 will make the cross plate 103 approach the plate. When the cross plate 103 moves, it will drive the first connecting rod 104 to move together.

After the stamping is completed, the first hydraulic cylinder 102 will move the cross plate 103 back. When the pressing plate 105 leaves the surface of the plate, the plate will move away from the surface of the workbench 106 under the elastic force of the spring 108. At this time, the staff can easily take out the stamped plate; when the plate and the top plate 110 come into contact, the plate will come into contact with the second telescopic rod 2. When the plate and the second telescopic rod 2 come into contact, the second telescopic rod 2 will be squeezed, and the second telescopic rod 2 will be compressed after being pressed; when the plate and the second telescopic rod 2 come into contact, the second telescopic rod 2 will be pressed. When the second telescopic rod 2 is squeezed, the pull rope 3 connects all the second telescopic rods 2 as a whole, thereby improving the supporting capacity of the second telescopic rod 2 for the pull rope 3; when the plate squeezes the second telescopic rod 2, the length of the second telescopic rod 2 will be shortened and the plate will be brought closer to the top plate 110. During the process, the plate will come into contact with the rubber pad 4. Because the rubber pad 4 is a flexible material, the rubber pad 4 will absorb the impact generated when the plate and the top plate 110 come into contact, thereby reducing the impact on the top plate 110 caused by the contact with the plate. At the same time, because the surface of the rubber pad 4 is a wavy structure, the contact area between the device and the plate will be increased, thereby increasing the friction between the device and the plate. When the first connecting rod 104 approaches the plate, the first connecting rod 104 The rod 104 will drive the second connecting rod 5 to move downward, and the second connecting rod 5 will drive the connecting plate 53 to move downward. When the connecting plate 53 moves, it will move together with the connecting rod 54. When the connecting rod 54 moves, it will move together with the piston 55. When the piston 55 moves, the air pressure at the bottom of the piston 55 will change. Under the squeezing action of the piston 55, the air at the bottom of the piston 55 will be ejected from the air pipe 56. The ejected air will reach the surface of the plate, reducing the dust on the surface of the plate and lowering the temperature of the surface of the plate. When the device blows air to the surface of the plate, the staff can slide the collecting box 6 along the slide groove 62 according to the blowing direction. After adjusting the position of the collecting box 6, the collecting box 6 will collect the impurities removed from the surface of the plate.When the device blows air to the surface of the plate, impurities will begin to diffuse under the action of the airflow. These impurities will reach the inside of the collection box 6 along the direction of the airflow. Some impurities will reach the surface of the curved plate 7, and then slide along the surface of the curved plate 7 to the inside of the collection box 6, thereby enhancing the collection function of the collection box 6. ;
