DETAILED DESCRIPTION

[0017] In order to make the personnel in the technical field better understand the technical scheme in the present application, the technical scheme in the embodiments of the present application will be described clearly and completely in the following by combining the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present patent, other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present patent.

[0018] The present embodiment provides a high-efficiency and precise butterfly-shaped anchor disc production device, which comprises an upper die holder 1 and a lower die holder 11. Figure 1 As shown in the drawings, the bottom of the upper die holder 1 is provided with an upper die set 2, and the upper die set 2 is provided with an upper punch 3.

[0019] In the present embodiment, the bottom of the upper die set 2 is provided with a concave die, which has a concave surface of bowl type to adapt to the shape requirement of the anchor disc. An upper punch 3 is further installed in the concave die, which can extend downward from the middle of the concave surface. In addition, the lower end of the upper punch 3 is further provided with a chamfer, so that when the middle part of the anchor disc is punched with a hole, the chamfer can be punched on the edge of the round hole by moving the upper punch downward.

[0020] The lower die set is located below the upper die set, and a lower punch 10 is installed inside the lower die set. The top of the lower punch 10 is a convex die. When the lower punch 10 moves upward, the convex die at the top can cooperate with the concave die at the bottom of the upper die set 2 to punch the plate into a concave shape. In this embodiment, a punch pin 9 is also installed through the lower punch 10, and the punch pin 9 can be extended upward from the middle of the lower punch 10. Thus, the disc-shaped punching and the center hole punching of the anchor plate can be completed at the same time in one punching process, greatly improving the production efficiency. It should be understood that the diameter of the punch pin 9 is smaller than the diameter of the upper punch 3, so as to ensure the correct formation of the hole chamfer.

[0021] In order to further optimize the production process of the device, a nitrogen spring and an upper ejector pin 4 are installed in the upper die set 2 in this embodiment. The upper part of the upper ejector pin 4 is connected with the nitrogen spring in the upper die set, and the lower part of the upper ejector pin 4 can extend out of the upper die set 2, thereby helping to prevent the punched anchor plate from sticking to the upper die set 2, thereby improving the quality of the product and the continuity of the production. Similarly, a nitrogen spring and a lower ejector pin 8 are also installed in the lower die set. The lower part of the lower ejector pin 8 is connected with the nitrogen spring in the lower die set, and the upper part of the lower ejector pin 8 can extend out of the lower die set, thereby helping to prevent the punched anchor plate from sticking to the lower die set.

[0022] In order to enhance the stability and accuracy of the device, a guide sleeve 5 is installed on one side of the upper die set 2, and a guide column 7 is fixed on the lower die seat 11 in this embodiment. The guide column 7 can cooperate with the guide sleeve 5 to ensure the accurate alignment of the upper die seat 1 and the lower die seat 11 during the die closing process, thereby improving the machining accuracy of the product.

[0023] In addition, in order to simplify the production process and improve the efficiency, a lower cutting knife 13 is fixed on the lower die seat 11, and an upper cutting knife 6 is fixed on the upper die seat 1 in this embodiment. Thus, the upper cutting knife 6 and the lower cutting knife 13 can simultaneously cut the plate into the required shape and size during the die closing process, without the need for additional cutting process.

[0024] Finally, in order to further improve the accuracy of positioning and the efficiency of production, a positioning block 12 is fixed on the lower die seat 11 on one side of the lower cutting knife 13 in this embodiment. The positioning block 12 helps to maintain the stable position of the plate during the punching process, preventing it from moving or shifting, thereby ensuring the machining quality of the product and the production efficiency.

[0025] Therefore, through the device, the one-time stamping forming scheme can be adopted, so that multiple processes such as disc-shaped stamping, center hole punching and orifice chamfering can be completed at the same time, and the production process is greatly simplified. At the same time, the setting of the nitrogen spring and the upper and lower ejector pins effectively prevents the adhesion problem between the anchor disc and the mold, improves the quality and continuity of production. In addition, the cooperation of the guide sleeve and the guide column and the design of the positioning block further improve the stability and accuracy of the device, ensuring the machining precision and production efficiency of the product.
