[0025] In order to automatically unload materials, there is no need for workers to manually load and unload materials, which reduces the labor burden of workers, avoids operating errors caused by workers' fatigue, and improves production safety and efficiency. The loading and unloading components 8 can automatically load and unload workpieces. The specific structure is: the loading and unloading components 8 include a material frame 81 and an electric cylinder 84. The material frame 81 is installed on the upper right part of the stamping plate 5, and the electric cylinder 84 is fixedly sleeved in the stamping plate 5. The lower left and lower right parts of the material frame 81 are jointly provided with a through groove 82, and a push plate 83 is movably connected in the through groove 82. The thickness of the through groove 82 is the same as the thickness of the plate. The output end of the electric cylinder 84 is fixedly connected to the right end of the predetermined push plate 83, and the lower end of the push plate 83 is movably contacted with the upper end of the stamping plate 5. The push plate 83 is used to push the plate near the through groove 82 to move and prevent the plate in the material frame 81 from moving downward.

[0026] A chute 15 is provided at the left end of the material box 2 . The material box 2 is located below the material chute 3 . The material box 2 is used to collect workpieces that have been stamped.

[0027] In order to reduce the height of the plate when it falls, avoid the damage to the surface of the plate caused by excessive impact force when it falls, and reduce the damage to the surface of the plate, the depth in the blanking box 2 can be adjusted by the buffer component 16. The specific structure is: the buffer component 16 includes a motor 161, the motor 161 is installed at the left end of the blanking box 2, the output end of the motor 161 is fixedly connected to a screw rod 162, the upper end of the screw rod 162 is movably connected to a bearing seat 163, the bearing seat 163 is installed on the blanking box 2, the outer surface of the screw rod 162 is threadedly sleeved with a moving block 164, and the moving block 164 is The right end passes through the slide slot 15 and is fixedly connected with a support plate 165. The outer surface of the support plate 165 is in active contact with the inner surface of the discharge box 2. The control motor 161 drives the screw rod 162 to rotate, and the screw rod 162 drives the support plate 165 to move upward through the moving block 164. The plate falls above the support plate 165 through the discharge chute 3, which can reduce the height of the plate when it falls. After a certain period of use, the control motor 161 drives the screw rod 162 to rotate, and the screw rod 162 drives the support plate 165 to move downward through the moving block 164, thereby gradually increasing the depth in the discharge box 2.
