[0021] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0022] like Figure 1 - Figure 4 As shown, a sheet metal stamping machine includes a mounting plate 1, a driving assembly and a pushing assembly. The side wall of the mounting plate 1 is fixedly connected to a cylinder base 2, and the side wall of the cylinder base 2 is fixedly connected to a support plate 3. The support plate 3 is located above the cylinder base 2, and a hydraulic cylinder 4 is installed on the support plate 3. The driving assembly is located on one side of the cylinder base 2, and the driving assembly drives the pushing assembly to operate.

[0023] Furthermore, the driving assembly includes a driving motor 11, a first gear 13 and a second gear 14. The driving motor 11 is located on one side of the cylinder base 2. The output shaft of the driving motor 11 is fixedly connected. The first gear 13 is meshed with the second gear 14. The second gear 14 is located above the first gear 13. The inner wall of the second gear 14 is fixedly connected with a second transmission shaft 15. The second transmission shaft 15 passes through the side wall of the mounting plate 1 and extends to the outside. When the driving motor 11 is started, the output shaft of the driving motor 11 drives the first transmission shaft 12 to rotate, the first transmission shaft 12 drives the first gear 13 to rotate, the first gear 13 drives the second gear 14 meshed therewith to rotate, the second gear 14 drives the second transmission shaft 15 to rotate, and the second transmission shaft 15 drives the turntable 16 to rotate, thereby driving the pushing assembly to move.

[0024] Furthermore, the pushing assembly includes a rectangular frame 6 and a rotating shaft 8. The side walls of the rectangular frame 6 are fixedly connected to the side walls of the mounting plate 1. The rectangular frame 6 is located above the driving motor 11. The inner wall of the rectangular frame 6 is provided with a plurality of symmetrically arranged rotating holes 7. Both ends of the rotating shaft 8 are rotatably connected to the inner walls of the corresponding rotating holes 7 respectively. A turntable 16 is arranged above the rectangular frame 6. The inner wall of the turntable 16 is fixedly connected to the circumference of the second transmission shaft 15. An arc-shaped pushing block 17 is fixedly connected to the circumference of the turntable 16, so that when the turntable 16 rotates, the arc-shaped pushing block 17 is driven to rotate. The arc-shaped pushing block 17 pushes the top surface of the metal plate so that the bottom surface of the metal plate drives the rubber ring 9 to move toward the direction of the cylinder base 2, thereby allowing the metal plate to move intermittently.

[0025] Furthermore, a plurality of guide bars 10 are fixedly connected to the top surface of the rectangular frame 6, and the guide bars 10 do not interfere with the arc-shaped push block 17, so that the arc-shaped push block 17 will not contact the guide bars 10 when rotating, thereby affecting the arc-shaped push block 17 to drive the metal plate to move.

[0026] Furthermore, a rubber ring 9 is fixedly connected to the circumference of the rotating shaft 8 . The diameter of the rubber ring 9 is greater than the height of the rectangular frame 6 , thereby increasing the friction between the metal plate and the rubber ring 9 and facilitating the movement of the metal plate.

[0027] Furthermore, the side wall of the oil cylinder base 2 is fixedly connected with a side plate 5 , and the side plate 5 is fixedly connected to the side wall of the rectangular frame 6 , so as to facilitate fixing the rectangular frame 6 and improve the firmness of the rectangular frame 6 .

[0028] Working principle: When a person wants to punch a metal plate, he first places the metal plate on the side of the rectangular frame 6 away from the cylinder base 2, and then starts the hydraulic cylinder 4 and the drive motor 11 respectively. At this time, the output shaft of the drive motor 11 drives the first transmission shaft 12 to rotate, the first transmission shaft 12 drives the first gear 13 to rotate, the first gear 13 drives the second gear 14 meshing therewith to rotate, the second gear 14 drives the second transmission shaft 15 to rotate, the second transmission shaft 15 drives the turntable 16 to rotate, the turntable 16 drives the arc push block 17 to rotate, and the arc push block 17 pushes the top of the metal plate The bottom surface of the metal plate drives the rubber ring 9 to move toward the direction of the cylinder base 2. At this time, multiple guide strips 10 limit the metal plate to avoid deviation when the metal plate moves. When the turntable 16 rotates to an angle where the arc-shaped push block 17 does not contact the metal plate, the metal plate stops moving, so that the metal plate can move intermittently. When the metal plate moves to the bottom of the hydraulic cylinder 4 and stops moving, the telescopic end of the hydraulic cylinder 4 can drive the stamping plate to stamp the metal plate. When the telescopic end of the hydraulic cylinder 4 drives the stamping plate to move upward, the metal plate continues to move to facilitate the next stamping.

[0029] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
