Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

An energy storage device 3 for storing downward pressing energy, releasing pushing materials and one-way transmission is installed on the right side of the pushing device 2.

[0026] In this embodiment: the stamping device 1 includes a frame 101, a hydraulic cylinder 102 is installed on the top of the frame 101, a lifting plate 103 is installed below the hydraulic cylinder 102, a punching head 104 is arranged below the lifting plate 103, a punching die 105 is arranged below the punching head 104, the lifting plate 103 is slidably connected to the frame 101, the workpiece is placed on the punching die 105, the frame 101 supports the hydraulic cylinder 102 to extend and drive the lifting plate 103 and the punching head 104 below to press down, so as to stamp the workpiece;

[0027] In this embodiment: the ejection device 2 includes a support seat 201, a rotating shaft 202 is rotatably installed on the top of the support seat 201, a cam 203 is installed on the rotating shaft 202, a push rod 204 is arranged above the cam 203, a top plate 205 is installed on the top of the push rod 204, the top plate 205 is circular in shape, and a silicone buffer layer is arranged on its surface. The cam 203 on the rotating shaft 202 rotates one circle under the support of the support seat 201, so that the push rod 204 on the cam 203 drives the top plate 205 to eject the workpiece and then reset it, thereby realizing automatic ejection;

[0028] In this embodiment: the energy storage device 3 includes an energy storage rod 301, a fixed block 302 is installed on the energy storage rod 301, a spring 304 is arranged under the fixed block 302, a rack 303 is installed in front of the fixed block 302, a power gear 305 is meshed in front of the rack 303, a movable gear 306 is meshed in front of the power gear 305, a transmission gear 309 is meshed in front of the movable gear 306, a limited position frame 308 is arranged behind the movable gear 306, a slider 307 is slidably installed inside the limited position frame 308, and the movable gear 306 is rotatably connected to the slider 307. The energy storage rod 301 is made of a cylindrical rod made of 204 stainless steel, and a smooth layer is arranged on the surface. The fixed block 302 is welded to the energy storage rod 301, the rack 303 is bolted to the energy storage rod 301, and the lifting plate 103 presses down the energy storage rod 301, so that the energy storage rod 30 1 drives the fixed block 302 to press the spring 304 to store energy. During the energy storage process, the fixed block 302 drives the rack 303 to move downward and mesh with the power gear 305 to rotate clockwise. The clockwise rotation of the power gear 305 will provide an upward force to the movable gear 306, pushing the movable gear 306 to move upward along the limit frame 308 under the support of the slider 307, so that the movable gear 306 cannot transmit the rotation of the power gear 305 to the transmission gear 309, thereby avoiding the impact of the material ejection during the downward pressing process on the stamping; after the stamping is completed, the lifting plate 103 rises, the spring 304 releases energy to push the fixed block 302 to drive the rack 303 to move upward, the rack 303 meshes with the power gear 305 to rotate counterclockwise, and the power gear 305 meshes with the transmission gear 309 through the movable gear 306 to drive the rotating shaft 202 to rotate to eject the material.

[0029] Working principle: The workpiece is placed on the stamping die 105, and the frame 101 supports the hydraulic cylinder 102 to extend and drive the lifting plate 103 and the punch head 104 below to press down to stamp the workpiece. At the same time, the lifting plate 103 presses down the energy storage rod 301, so that the energy storage rod 301 drives the fixed block 302 to press down the spring 304 to store energy. During the energy storage process, the fixed block 302 drives the rack 303 to move downward and engage the power gear 305 to rotate clockwise. The clockwise rotation of the power gear 305 will provide an upward force to the movable gear 306, pushing the movable gear 306 to move upward along the limit frame 308 under the support of the slider 307. The movable gear 306 is incapable of transmitting the rotation of the power gear 305 to the transmission gear 309, thereby avoiding the impact of the ejection of the material during the pressing process on the stamping; after the stamping is completed, the lifting plate 103 rises, and the spring 304 releases energy to push the fixed block 302 to drive the rack 303 to move upward, and the rack 303 engages with the power gear 305 to rotate counterclockwise. The power gear 305 engages with the transmission gear 309 through the movable gear 306 to drive the cam 203 on the rotating shaft 202 to rotate one circle under the support of the support seat 201, so that the ejector rod 204 on the cam 203 drives the ejector plate 205 to eject the workpiece and then reset it, thereby realizing automatic ejection.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
