[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Reference Figures 1-5 The stamping mechanism of the stamping machine shown includes a stamping machine base 1, a lower die 2, a pressure plate 3, and a hydraulic rod 4. The lower die 2, the pressure plate 3, and the hydraulic rod 4 are all located on the top of the stamping machine base 1. A U-shaped protective plate 5 is provided on the top of the stamping machine base 1. A rectangular groove is provided on one side of the U-shaped protective plate 5. An opening and closing mechanism is rotatably arranged in the rectangular groove. The opening and closing mechanism is used to close and protect the machine during the stamping process.

[0025] The opening and closing mechanism includes a rotating shaft 6 and a rotating rod 7. Two square slots are opened at the bottom of the rectangular slot. The bottom ends of the rotating shaft 6 and the rotating rod 7 are rotatably installed on the bottom inner walls of the two square slots, respectively. The top ends of the rotating shaft 6 and the rotating rod 7 are rotatably installed on the top inner wall of the rectangular slot. The rotating shaft 6 and the rotating rod 7 are connected by a transmission component. Side protective plates 8 and front protective plates 9 are fixedly sleeved on the rotating shaft 6 and the rotating rod 7, respectively. The bottom end of the rotating shaft 6 is provided with a linkage component that is compatible with the pressure plate 3.

[0026] With the above structure, when the pressure plate 3 moves downward, the linkage component drives the rotating shaft 6 and rotating rod 7 to rotate synchronously, thereby driving the side protective plate 8 and front protective plate 9 to rotate synchronously, realizing the closing function and preventing debris from flying and injuring workers during the stamping process. When the stamping operation is completed, when the pressure plate 3 moves upward to the appropriate position, the linkage component drives the rotating shaft 6 and rotating rod 7 to rotate in the opposite direction, thereby driving the side protective plate 8 and front protective plate 9 to rotate synchronously, thus realizing the opening function. No manual operation by the staff is required, the opening and closing effect is stable, and it is highly practical.

[0027] like Figure 3 As shown, the transmission assembly includes two sprockets 11, which are fixedly sleeved on the outer periphery of the rotating shaft 6 and the rotating rod 7, respectively. The inner side walls of the two square slots that are close to each other are provided with a connecting hole. A chain 12 is meshed on the two sprockets 11. Through the meshing action of the sprockets 11 and the chain 12, the rotating shaft 6 and the rotating rod 7 can rotate synchronously. The chain 12 is set in the connecting hole.

[0028] Specifically, when the shaft 6 rotates, it drives one of the sprockets 11 to rotate, which in turn drives the other sprocket 11 and the rotating rod 7 to rotate synchronously under the meshing action of the chain 12, so that the side guard plate 8 and the front guard plate 9 can rotate.

[0029] like Figure 1 As shown, an observation hole is provided on the side of the front protective plate 9, and an observation window 10 is provided inside the observation hole. The stamping process can be observed through the observation window 10.

[0030] Specifically, during the stamping process, it can be observed through the observation window 10, and no debris will fly out, providing good protection.

[0031] like Figure 5As shown, the linkage assembly includes a rectangular moving plate 15. A transmission cavity is formed within the U-shaped protective plate 5. The rectangular moving plate 15 is slidably installed within the transmission cavity via a moving unit. A rotating unit adapted to the rotating shaft 6 is provided on the side of the rectangular moving plate 15. The moving unit includes a screw 16, with both ends of the screw 16 rotatably mounted on opposite inner walls of the transmission cavity. The rectangular moving plate 15 is threaded onto the screw 16. Rotation of the screw 16 enables the rectangular moving plate 15 to achieve horizontal movement. A fitting adapted to the pressure plate 3 is provided on the screw 16. The control element, the rotating unit, includes a transverse rack 13. Each of the square slots has a sliding hole on its inner wall. One of the sliding holes is connected to the transmission cavity. The transverse rack 13 is slidably disposed in the two sliding holes. One side of the transverse rack 13 is fixedly connected to one side of the rectangular moving plate 15. A first gear 14 is fixedly sleeved on the outer wall of the rotating shaft 6. The first gear 14 is meshed with the transverse rack 13. The horizontal movement of the rectangular moving plate 15 drives the transverse rack 13 to mesh with the first gear 14, thereby driving the rotating shaft 6 to achieve the rotation function.

[0032] Specifically, when the screw 16 rotates, it can drive the rectangular moving plate 15 to move horizontally through the thread action, thereby driving the transverse rack 13 to move synchronously and mesh with the first gear 14, so that the first gear 14 drives the rotating shaft 6 to achieve the rotation function, thereby driving the side protection plate 8 to flip.

[0033] like Figure 5 As shown, the control element includes a second gear 17, which is fixedly sleeved on the outer peripheral wall of the screw 16. A lifting hole is provided on the inner side wall of the transmission cavity, and a connecting block 18 is slidably installed in the lifting hole. One side of the connecting block 18 is fixedly connected to the side of the pressure plate 3, and a longitudinal rack 19 is provided on the other side of the connecting block 18. The longitudinal rack 19 is meshed with the second gear 17. Through the meshing action of the longitudinal rack 19 and the second gear 17, the screw 16 can be driven to rotate.

[0034] Specifically, when the pressure plate 3 moves downward, it can drive the connecting block 18 and the longitudinal rack 19 to move downward synchronously. Thus, through the meshing of the longitudinal rack 19 and the second gear 17, the screw 16 is driven to rotate, thereby driving the rectangular moving plate 15 to move under the action of the screw.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
