[0022] For ease of understanding, Figure 1 The structural diagram of the product in this embodiment is shown, and it can be seen that one end thereof extends outward to form two side wings 7, and a rivet 6 is vertically installed on each side wing 7. If one side is first riveted and then the other side is riveted according to the conventional riveting process, not only is the efficiency low, but also a large positioning fixture is required to position the plate body and the side wing respectively. It is also easy to change the angle between the side wing 7 and the plate body or affect the flatness of the side wing 7 during the production process, resulting in unstable quality and high cost of the side wing riveting process.

[0023] like Figure 2 As shown, the utility model discloses a stamping die for riveting rivets on the side wings of metal plates. The stamping die includes an upper die 100 and a lower die 200. A lower die plate 10 is arranged on the lower die 200.

[0024] The lower template 10 is vertically placed on the upper end of the lower mold 200 and extends toward the upper mold 100. At least one side wall thereof is adapted to the end of the product. A lower pad 20 is provided at the lower end of the lower template 10. The lower pad 20 is adapted to the side end of the product. One or more clamping members 1 are provided on both sides of the lower template 10 above the lower pad 20. Each clamping member 1 is mounted on the lower mold 200 through a positioning block 2. Several clamping members 1 can press the product against the lower template 10.

[0025] A riveting rod 3 is provided on both sides of the lower mold plate 10 on the upper mold 100; when the mold is closed, the upper mold 100 can drive the two riveting rods 3 to move toward the product to press the rivets placed on its side wings into the product and simultaneously press the product against the lower pad 20 for flattening and shaping.

[0026] During production, in the mold open state, the metal plate is placed upright against the lower mold plate 10 and its lower end and two side wings 7 are against the lower pad 20, and then the two clamping parts 1 are respectively placed against the metal plate and pressed against the lower mold plate 10, and finally the two rivets 6 are respectively placed on the ends of the through holes on the side wings 7 to be riveted. After completion, the mold is started, and the upper mold 100 drives the two riveting rods 3 to move toward the lower mold, punching the rivet 6 through the through hole and fixing it on the side wings, and at the same time, the side wings 7 are pressed against the lower pad 20 to level it or adjust its contour structure.

[0027] Furthermore, an avoidance hole groove 4 for avoiding rivets is provided on the lower pad 20 below the product side wing; a positioning member 5a and / or a limiting member 5b is also provided on the lower pad 20 beside the lower template 10.

[0028] It can be understood that the avoidance hole groove 4 can ensure that the rivet 6 can smoothly pass through the through hole on the side wing 7; the positioning member 5a and the limit member 5b can cooperate with the clamping member 1 to press different parts of the metal plate, ensuring that they are tightly pressed against the lower template 10 or limiting the displacement of the plate body during the leveling / shaping process of the side wing 7, thereby ensuring the shape and position accuracy of the plate body and the side wing 7.

[0029] Furthermore, the lower end of each riveting rod 3 is adapted to the product side wing 7 .

[0030] In application, the bottom end profile of the rivet rod 3 can be set according to the profile of the side wing 7, so that the profile of the side wing 7 can be adjusted while leveling it.

[0031] Furthermore, the upper mold 100 is provided with an upper mold base 30, an upper clamping plate 40 and an upper pad 50. The upper pad 50 is arranged above the lower mold 10 and fixed to the upper mold base 30 through the upper clamping plate 40. When the mold is fully closed, the upper pad 50 is located above the lower mold 10 or is attached to the upper end of the lower mold 10.

[0032] It is understandable that if Figure 2 As shown, when the mold is fully closed, the upper pad 50 is close to or against the upper end of the lower mold plate 10, which can prevent the upper mold from damaging the lower mold plate 10 and the product in abnormal situations such as size or installation errors of the rivet rod 3.

[0033] In some embodiments of the present invention, each clamping member 1 can rotate or translate relative to the lower mold plate 10; each positioning block 2 can be detachably fixed on the lower mold 200, and at least one clamping member 1 is movably mounted thereon.

[0034] In other embodiments of the present invention, each positioning block 2 can translate or rotate on the lower mold 200, and a clamping member 1 can be detachably fixed or movably mounted thereon.

[0035] In application, according to the specific structure of the upper mold 100 and the lower mold 200 and the limitations and positioning requirements of the metal plate's own structure, the relative position of the clamping member 1 and the metal plate and the clamping trajectory during the clamping process can be changed by reasonably designing the connection relationship between the positioning block 2 and the lower mold 200 and the connection relationship between the positioning block 2 and the clamping member 1, so as to achieve the purpose of clamping a specific position on the metal plate or avoiding a specific structure thereon, and ensure that the rivet rod 3 will not interfere with the clamping member 1 in position and structure during the mold closing process.

[0036] The utility model vertically mounts the lower template 10 on the lower mold 200 and sets a clamping piece 1 beside it, and sets a riveting rod 3 on the upper mold 100, so that the metal plate can be placed upright on the lower mold 200 and fixed when the mold is opened, and the rivet 6 is pressed into the side wing 7 by the mold clamping force, and the flatness of the side wing 7 and the shape and position accuracy with the metal plate body can be ensured; by changing the connection relationship between the positioning block 2 and the lower mold 200 and / or the connection relationship between the positioning block 2 and the clamping piece 1, the relative position of the clamping piece 1 and the metal plate and its clamping trajectory can be changed to achieve the purpose of clamping a specific position on the metal plate or avoiding a specific structure thereon, and ensure that the riveting rod 3 will not interfere with the clamping piece 1 in position and structure during the mold clamping process, the overall structure is simple and easy to assemble, the stamping quality is stable, and the yield rate is high.

[0037] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
