When the third rotating shaft 84 rotates, it drives the gear 86 to rotate, and the rack 87 meshing with the gear 86 slides, thereby realizing the function of pushing the material body.

[0039] Among them, the feeding mechanism 25 further includes a first sliding table 250, a pressure sensor 251, a fixing block 252, an electric push rod 253, a first pushing plate 254, and a controller 255. The bottom of the first sliding table 250 is fixedly connected to the top of the bottom plate 1. The pressure sensor 251 is arranged on the surface of the first sliding table 250.

[0040] By setting the pressure sensor 251, when the material body is conveyed to the first sliding table 250, the pressure sensor 251 senses the pressure and transmits the signal to the controller 255. After receiving the signal, the controller 255 controls the electric push rod 253 to push the material body onto the mold table 70, realizing the function of automatic feeding of the material body.

[0041] The working process of the present utility model is as follows:

[0042] First, the material body slides down through the first blanking plate 21 in the blanking table 20 onto the conveyor belt 22, is transported by the conveyor belt 22 to the second blanking plate 24, and then slides into the first sliding table 250 under the action of gravity. A pressure sensor 251 is provided on the upper part of the first sliding table 250. When the pressure sensor 251 senses that a material body has fallen in, it feeds back a signal to the controller 255. The controller 255 controls the electric push rod 253 to push the material body onto the mold table 70, enabling the material body to automatically reach the mold;

[0043] Then, when the material body reaches the mold table 70, the upper stamping mold 6 drives the first rotating shaft 80 to move downward. At the same time, the long connecting rod 81 and the short connecting rod 83 also move downward simultaneously, driving the third rotating shaft 84 to rotate clockwise. At the same time, the gear 86 also rotates clockwise, and the gear 86 drives the rack 87 and the second pushing plate 89 to move backward;

[0044] Finally, after stamping is completed, a spring 71 and a spring plate 72 are provided in the middle of the mold table 70, and the material body returns to its original position following the spring plate 72; the long connecting rod 81 and the short connecting rod 83 move upward following the first rotating shaft 80, driving the third rotating shaft 84 to rotate counterclockwise. At this time, the rack 87 drives the second pushing plate 89 to move forward, pushing the material body that has returned to its original position out of the mold table 70, thus achieving bending and automatic blanking of the material body.

[0045] During the entire process from feeding to stamping and then to blanking, only the staff needs to assist in placing the material body into the blanking table 20. The staff does not need to directly contact the stamping mold during feeding and blanking. This not only improves production safety but also increases production efficiency.
