[0023] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. 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.

[0024] like Figures 1 to 4 As shown, a capacitor tantalum cover flanging device comprises: a bottom plate 1, a base 6 and a top support 14,

[0025] The side end of the bottom plate 1 is fixedly connected with a support plate 2, the top of the support plate 2 is fixedly connected with a punching machine 3, the bottom end of the punching machine 3 is fixedly connected with a punching rod 4, the bottom plate 1 has a supporting connection function, the punching machine 3 is installed on the bottom plate 1 through the support plate 2, so that the punching machine 3 and the base 6 cooperate to operate;

[0026] The base 6 is fixedly connected to the top of the bottom plate 1, and the base 6 is provided with slide grooves 8 around each other. The top of the base 6 is provided with a flanging groove 7 around the center line of the punching rod 4, and the base 6 is provided with a limiting groove 13 around the center line of the punching rod 4. A slide seat 11 is slidably connected in the slide groove 8, and a limiting clamping plate 9 is provided at the side end of the slide seat 11 close to the punching rod 4. The flanging groove 7 and the limiting groove 13 are not connected to each other. In order to avoid the tantalum cover raw material from shifting during stamping, the tantalum cover raw material is placed on the base 6, and the slide seat 11 is slid in the slide groove 8. The slide seat 11 drives the limiting clamping plate 9 to limit the tantalum cover raw material. When the tantalum cover raw material is stamped, the tantalum cover raw material will not shift after being limited by the limiting clamping plate 9, thereby ensuring the product quality of the capacitor tantalum cover; and

[0027] The top holding seat 14 is slidably connected in the limiting groove 13, and the top holding seat 14 supports the tantalum cap raw material. When the tantalum cap raw material begins to be subjected to force for stamping, the tantalum cap raw material and the top holding seat 14 move downward, and the top holding seat 14 slides along the limiting groove 13. When the tantalum cap raw material contacts the top of the base 6, the top holding seat 14 completely extends into the limiting groove 13, and the tantalum cap raw material begins to be stamped.

[0028] In some specific embodiments, a stamping plate 5 is fixedly connected to the bottom end of the stamping rod 4, and the inner diameter of the stamping plate 5 is larger than the inner diameter of the flanging groove 7. The operation of the punching machine 3 drives the stamping rod 4 to move downward, and the stamping rod 4 drives the stamping plate 5 to move downward. The stamping plate 5 pushes the tantalum cover raw material downward. When the tantalum cover raw material and the top of the base 6 are pressed against each other, the stamping plate 5 continues to move downward, and the stamping plate 5 extends into the flanging groove 7. The tantalum cover raw material is forced to enter the flanging groove 7, thereby completing the flanging processing of the tantalum cover raw material.

[0029] In some specific implementation schemes, an extension plate 10 is provided between the slide 11 and the limiting clamp 9. The slide 11 is provided with a threaded hole 19 which is parallel to the center line of the slide groove 8 and passes through the slide 11. Both ends of the extension plate 10 are fixedly connected to the slide 11 and the limiting clamp 9 respectively. In order to extend the limiting effect of the limiting clamp 9 on the tantalum cover raw material, the slide 11 is connected through the connection structure of the extension plate 10. When the slide 11 moves, the limiting clamp 9 is closer to the flanging groove 7. The limiting clamp 9 can limit tantalum cover raw materials of different sizes, further improving the applicability of the limiting clamp 9.

[0030] In some specific embodiments, a threaded rod 12 is threadedly connected to the threaded hole 19, and the threaded rod 12 is rotationally connected to the slide groove 8 at the side end near the limiting clamp 9. In order to illustrate the movement of the slide 11 in the slide groove 8 in detail, the threaded rod 12 is rotated, and the threaded rod 12 drives the slide 11 to move through the threaded connection with the threaded hole 19. The rotational connection between the threaded rod 12 and the slide groove 8 can ensure the stability of the rotation of the threaded rod 12. At the same time, when the threaded rod 12 stops rotating, the threaded rod 12 fixes the slide 11 through the threaded connection with the threaded hole 19.

[0031] In some specific embodiments, a spring 15 is provided between the base plate 1 and the top holding seat 14. The base plate 1 is fixedly connected with a positioning column 16 in a direction parallel to the center line of the top holding seat 14. The upper and lower ends of the spring 15 are respectively fixedly connected to the top holding seat 14 and the base plate 1. In order to prevent the tantalum cover raw material from being difficult to remove from the base 6 after the flanging process, when the tantalum cover raw material is flanging, the top holding seat 14 moves upward by the elastic force provided by the spring 15. The top holding seat 14 moves the tantalum cover raw material upward, and the flanging edge of the tantalum cover raw material extends out from the flanging groove 7, thereby facilitating the removal of the tantalum cover raw material after flanging.

[0032] In some specific implementation schemes, the two ends of the supporting seat 14 are respectively fixedly connected with the limiting plates 18 in the longitudinal direction, and the supporting seat 14 is provided with a positioning hole 17 along the center line in the longitudinal direction. The limiting plate 18 is slidably connected with the limiting groove 13, and the top of the limiting plate 18 is abutted against the limiting groove 13. The positioning hole 17 is slidably connected with the positioning column 16. In order to ensure the stability of the movement of the supporting seat 14 in the limiting groove 13, the two ends of the supporting seat 14 are limited by the fixed limiting plates 18, and the limiting effect provided by the limiting groove 13 is transmitted to the supporting seat 14 through the limiting plates 18 to prevent the supporting seat 14 from rotating on its own, thereby causing the tantalum cap raw material to rotate on the supporting seat 14. Among them, the positioning column 16 slides in the positioning hole 17 to position and guide the supporting seat 14 when it moves. At the same time, the positioning column 16 limits the spring 15 to prevent the spring 15 from bending.

[0033] In order for those skilled in the art to better understand the working principle of the embodiments of the present invention, the following is an explanation in conjunction with specific application scenarios:

[0034] The threaded rod 12 is rotated, and the threaded rod 12 drives the slide seat 11 to slide in the slide groove 8 through the threaded connection with the threaded hole 19. The slide seat 11 drives the limit clamping plate 9 to move through the extension plate 10, and the tantalum cover raw material is placed on the top holding seat 14. The limit clamping plate 9 limits the tantalum cover raw material around. The punching machine 3 is started, and the punching machine 3 drives the punching rod 4 to move downward, and the punching rod 4 drives the punching plate 5 to move downward, and the punching plate 5 drives the tantalum cover raw material and the top holding seat 14 to move downward. When the tantalum cover raw material is pressed, the punching rod 4 is pressed downward, and the punching plate 5 drives the tantalum cover raw material and the top holding seat 14 to move downward. When the material and the top of the base 6 are against each other, the top holding seat 14 is completely extended into the limiting groove 13. At the same time, the spring 15 is compressed in the limiting groove 13, and the positioning column 16 slides along the positioning hole 17. When the stamping plate 5 continues to move downward, the stamping plate 5 pushes the tantalum cover raw material into the flanging groove 7, and the tantalum cover raw material completes the flanging process. When the tantalum cover raw material is stamped, the tantalum cover raw material will not deviate after being limited by the limiting clamping plate 9, thereby ensuring the product quality of the capacitor tantalum cover;

[0035] Among them, in order to extend the limiting effect of the limiting clamp plate 9 on the tantalum cover raw material, the slide 11 acts through the connecting structure of the extension plate 10. When the slide 11 moves, the limiting clamp plate 9 is closer to the flanging groove 7. The limiting clamp plate 9 can limit tantalum cover raw materials of different sizes, further improving the applicability of the limiting clamp plate 9. After the tantalum cover raw material is flanging, the top holding seat 14 moves upward through the elastic force provided by the spring 15. The top holding seat 14 moves the top tantalum cover raw material upward, and the flanging edge of the tantalum cover raw material extends out from the flanging groove 7. , so as to facilitate the removal of the tantalum cap raw material after flanging. The two ends of the top holding seat 14 are limited by fixed limiting plates 18. The limiting effect provided by the limiting groove 13 is transmitted to the top holding seat 14 through the limiting plate 18 to prevent the top holding seat 14 from rotating, thereby causing the tantalum cap raw material to rotate on the top holding seat 14. Among them, the positioning column 16 slides in the positioning hole 17 to position and guide the top holding seat 14 when moving. At the same time, the positioning column 16 limits the spring 15 to prevent the spring 15 from bending.

[0036] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
