Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment: Refer to Figures 1-5, A cold heading device for nut production, including a bottom plate 1. Above the bottom plate 1, there is a stamping and forming assembly. On the top side of the bottom plate 1, a fixed table 7 is fixedly installed. Above the fixed table 7, a rotating table 8 is arranged. The rotating table 8 is provided with a forming groove 9. On the bottom inner wall of the forming groove 9, a communication hole 19 is opened. The rotating table 8 is provided with a round hole. Between the fixed table 7 and the rotating table 8, a guiding assembly is arranged. The fixed table 7 is respectively provided with a discharge hole 12 and a placement hole 13. Both the placement hole 13 and the discharge hole 12 are communicated with the communication hole 19. The discharge hole 12 is adapted to the round hole. On the bottom side of the bottom plate 1, a first electric push rod 20 is fixedly installed. The output end of the first electric push rod 20 penetrates through the bottom plate 1 and is fixedly connected with a push block 21. The push block 21 is located in the placement hole 13. Both the fixed table 7 and the bottom plate 1 are provided with round holes. In the round holes, there is the same rotating rod 14. The top end of the rotating rod 14 is fixedly connected to the bottom side of the rotating table 8. The bottom end of the rotating rod 14 is fixedly sleeved with a first belt pulley 15. Below the bottom plate 1, a linkage assembly is arranged. The linkage assembly includes a motor 16 fixedly installed on the top side of the bottom plate 1. The output end of the motor 16 rotates through the bottom plate 1 and is fixedly sleeved with a second belt pulley 17. Between the second belt pulley 17 and the first belt pulley 15, there is the same belt 18. By setting the motor 16, after extrusion forming, the air cylinder 3 drives the connecting plate 4 to move upward. Subsequently, the motor 16 operates to drive the second belt pulley 17 to rotate counterclockwise. And because the second belt pulley 17 and the first belt pulley 15 share the same belt 18, under the driving action of the belt 18, the first belt pulley 15 drives the rotating rod 14 to rotate, and then the rotating rod 14 drives the rotating table 8 to rotate synchronously. When the forming groove 9 rotates above the discharge hole 12, the motor 16 stops operating. Subsequently, the air cylinder 3 is started to drive the connecting plate 4 to move downward, so that the punching die 6 fixedly installed on the bottom side of the connecting plate 4 passes through the round hole opened in the baffle 22 and moves towards the flat blank, thereby completing the punching process of the formed blank. And the punched blank will fall into the collection box 27 along the discharge hole 12 for storage, which is convenient for subsequent unified processing. After punching is completed, the air cylinder 3 operates to drive the connecting plate 4 to move upward, so that the punching die 6 moves out of the forming groove 9 and the discharge hole 12. And when discharging is required, the motor 16 operates again to drive the rotating table 8 to rotate. When the forming groove 9 moves above the placement hole 13, the motor 16 stops operating. Subsequently, the first electric push rod 20 is started to drive the push block 21 to move upward. When the push block 21 moves upward, it pushes out the processed nut in the forming groove 9. Then, the second electric push rod 24 is started to drive the push plate 25 to push the finished nut into the finished product box 26. And after completing this whole process, the motor 16 operates again to drive the rotating table 8 to rotate. When the forming groove 9 rotates below the pressing die 5, place the next nut blank, and then repeat the above operations.

[0024] Specifically, the stamping and forming assembly includes a bracket 2 fixedly installed on the top side of the bottom plate 1. The bracket 2 is L-shaped. A cylinder 3 is fixedly installed on the top side of the bracket 2. The output end of the cylinder 3 penetrates through the bracket 2 and is fixedly connected to a connecting plate 4. A pressing die 5 and a punching die 6 are respectively fixedly installed on the bottom side of the connecting plate 4. The pressing die 5 faces the forming groove 9. The punching die 6 is adapted to the round hole opened in the rotating table 8 and the material discharging hole 12 opened in the fixed table 7. By operating the cylinder 3 to drive the connecting plate 4 to move downward, the pressing die 5 and the punching die 6 respectively fixedly connected below the connecting plate 4 move toward the forming groove 9 and the round hole. The pressing die 5 can stamp the nut blank in the forming groove 9 into the required shape, and the punching die 6 can punch the formed nut.

[0025] Specifically, the guiding assembly includes a sliding groove 11 opened on the outer side of the fixed table 7. A plurality of sliders 10 slide in the sliding groove 11. The inner sides of the plurality of sliders 10 are fixedly connected to the outer side of the rotating table 8. By providing a plurality of sliders 10, when the rotating table 8 rotates, the plurality of sliders 10 will slide in the sliding groove 11 opened in the fixed table 7, so as to be able to limit and guide the rotating table 8 and avoid the situation of shaking up and down.

[0026] Specifically, a fixing frame 23 is fixedly installed on one side of the bracket 2. The fixing frame 23 is L-shaped. A second electric push rod 24 is fixedly installed on one side of the fixing frame 23. The output end of the second electric push rod 24 penetrates through the fixing frame 23 and is fixedly connected to a push plate 25. The push plate 25 faces the placing hole 13. A baffle 22 is fixedly installed on the top side of the bottom plate 1. The baffle 22 is L-shaped. A round hole is opened on the top side of the baffle 22. The round hole is adapted to the round hole opened in the rotating table 8. A finished product box 26 is placed on the top side of the bottom plate 1. The finished product box 26 is located on one side of the fixed table 7 and the rotating table 8. A collecting box 27 is arranged below the bottom plate 1. The material discharging hole 12 faces the collecting box 27. By providing the baffle 22, it can prevent the punching die 6 from driving the nut to move up synchronously when moving up. And by providing the finished product box 26 and the collecting box 27, the collecting box 27 can collect the ingredients falling from the material discharging hole 12, which is convenient for subsequent unified treatment. And by providing the push plate 25, after the push block 21 pushes up the nut in the forming groove 9, start the second electric push rod 24 to drive the push plate 25 to move toward the finished nut, and the finished nut can be pushed toward the finished product box 26, and then the nut will fall into the finished product box 26, which is convenient for subsequent unified collection.

[0027] All the electrical components mentioned in this article are electrically connected to the external main controller and 220V mains power, and the main controller can be a conventional known device such as a computer for control.

[0028] During use: Place the nut blank into the forming groove 9. Subsequently, the cylinder 3 operates to drive the connecting plate 4 downward, so that the pressing die 5 fixedly installed on the bottom side of the connecting plate 4 presses towards the nut blank, and thus the nut blank is pressed and formed by the pressing die 5. After the pressing and forming, the cylinder 3 drives the connecting plate 4 upward. Subsequently, the motor 16 operates to drive the second pulley 17 to rotate counterclockwise. And because the second pulley 17 and the first pulley 15 share the same belt 18, under the driving action of the belt 18, the first pulley 15 drives the rotating rod 14 to rotate, and thus the rotating rod 14 drives the rotating table 8 to rotate synchronously. When the forming groove 9 rotates above the discharge hole 12, the motor 16 stops operating. Subsequently, the cylinder 3 is started to drive the connecting plate 4 downward, so that the punching die 6 fixedly installed on the bottom side of the connecting plate 4 moves through the circular hole opened in the baffle 22 towards the flat blank, and thus the punching process of the formed blank is completed. And the blank after punching will fall into the collection box 27 through the discharge hole 12 for storage, which is convenient for subsequent unified processing. After the punching is completed, the cylinder 3 operates to drive the connecting plate 4 upward, so that the punching die 6 moves out of the forming groove 9 and the discharge hole 12. And through the arranged baffle 22, it can be avoided that the punching die 6 drives the nut to move upward synchronously when moving upward. And when discharging is required, the motor 16 operates again to drive the rotating table 8 to rotate. When the forming groove 9 moves above the placing hole 13, the motor 16 stops operating. Subsequently, the first electric push rod 20 is started to drive the push block 21 upward. The push block 21 pushes out the nut processed in the forming groove 9 when moving upward. Then the second electric push rod 24 is started to drive the push plate 25 towards the finished nut, and the finished nut can be pushed towards the finished product box 26. Subsequently, the nut will fall into the finished product box 26. After completing this entire process, the motor 16 operates again to drive the rotating table 8 to rotate. When the forming groove 9 rotates below the pressing die 5, place the next nut blank, and then repeat the above operations.
