Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0015] Such as Figure 1-2As shown in the figure, a heat sink stamping device includes a workbench 1. A through groove 1-1 is formed in the workbench 1. A pair of rotating plates 5 are rotatably arranged in the through groove 1-1. A driving component capable of driving the rotating plates 5 to rotate is arranged on the workbench 1. Multiple pairs of sliding grooves 5-1 are formed in each rotating plate 5. A limiting rod 6 is arranged in each sliding groove 5-1. A sliding bar 8 is slidably arranged in each pair of sliding grooves 5-1 with opposite positions on the pair of rotating plates 5. The end of the sliding bar 8 is slidably sleeved on each limiting rod 6. A spring 7 is sleeved on each limiting rod 6. A transmission plate 9 is arranged between each adjacent pair of sliding bars 8. On one side of each transmission plate 9 close to the center of the rotating plate 5, an upper pressing die 10 is arranged. Multiple lower pressing dies 11 are arranged between the pair of rotating plates 5 and at positions corresponding to each upper pressing die 10. The shapes or sizes of each group of the upper pressing dies 10 and the lower pressing dies 11 are different. A lower pressing component capable of moving the upper pressing die 10 towards the lower pressing die 11 is arranged on the workbench 1. The driving component includes a pair of fixing plates 2, a servo motor 3 and a rotating shaft 4. The pair of fixing plates 2 are arranged at the bottom of the workbench 1. The servo motor 3 is arranged on one of the fixing plates 2 and its output end is connected to the rotating shaft 4. The rotating shaft 4 is rotatably arranged on the pair of fixing plates 2 and penetrates through the center positions of the pair of rotating plates 5. The lower pressing component includes a pair of vertical plates 12, a top plate 13, a hydraulic cylinder 14 and a pressing plate 15. The pair of vertical plates 12 are oppositely arranged on the upper surface of the workbench 1. The top plate 13 is arranged at the top of the pair of vertical plates 12. The hydraulic cylinder 14 is arranged at the bottom of the top plate 13. The pressing plate 15 is arranged on the telescopic end of the hydraulic cylinder 14.

[0016] The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, which are as follows:

[0017] In the present utility model, both the servo motor 3 and the hydraulic cylinder 14 are connected to an external electronic control system through wires. The above devices and connection methods are all prior arts and will not be elaborated here.

[0018] According to the attached drawings of the specification Figure 1-2It can be seen that when the present utility model is in use, a pair of rotating plates 5 are driven to rotate by a driving component. When the rotating plates 5 rotate, a plurality of lower pressing dies 11 and sliding bars 8 slidably arranged in the sliding grooves 5-1 formed thereon are driven to rotate. Each pair of sliding bars 8 drives the transmission plate 9 therebetween to rotate, and the transmission plate 9 drives the connected upper pressing die 10 to rotate. Thus, a set of upper pressing die 10 and lower pressing die 11 that meet the stamping requirements rotate to the lower part of the lower pressing component. The sheet material is placed between the upper pressing die 10 and the lower pressing die 11 located above. The lower pressing component is started, and the lower pressing component presses on the transmission plate 9. The transmission plate 9 drives the upper pressing die 10 to move vertically downward. At the same time, the transmission plate 9 drives the two connected sliding bars 8 to move. The end of each sliding bar 8 slides in the sliding groove 5-1, and the limiting rod 6 limits the sliding bar 8 to prevent the sliding bar 8 from disengaging from the sliding groove 5-1. When the sliding bar 8 moves, the spring 7 sleeved on the limiting rod 6 is compressed, so that the upper pressing die 10 and the lower pressing die 11 cooperate to stamp the sheet material. After the stamping is completed, the moving part of the lower pressing component returns to its original position. Under the elastic force of the spring 7, a pair of sliding bars 8 move vertically upward. A pair of sliding bars 8 drive the transmission plate 9 to move, and the transmission plate 9 drives the upper pressing die 10 to move. Then the operator takes out the stamped heat sink from the lower pressing die 11; the present utility model drives multiple sets of upper pressing dies 10 and lower pressing dies 11 to rotate through the driving component, so that a set of upper pressing die 10 and lower pressing die 11 that meet the stamping requirements rotate to the lower part of the lower pressing component. When heat sinks of multiple shapes need to be stamped, there is no need for the operator to repeatedly replace the stamping die, which saves time and effort for the operator and improves the stamping efficiency.

[0019] There is a possible implementation. When the output end of the servo motor 3 rotates, the connected rotating shaft 4 is driven to rotate. The rotating shaft 4 passes through the central positions of a pair of rotating plates 5 and is fixedly connected to the pair of rotating plates 5. When the rotating shaft 4 rotates, the pair of rotating plates 5 are driven to rotate. When the pair of rotating plates 5 rotate, multiple sets of upper pressing dies 10 and lower pressing dies 11 are driven to rotate, and thus the positions of each set of upper pressing die 10 and lower pressing die 11 are adjusted through the servo motor 3.

[0020] There is a possible implementation. When the hydraulic cylinder 14 provided at the bottom of the top plate 13 is started, the telescopic end of the hydraulic cylinder 14 drives the connected pressing plate 15 to move vertically downward, and the pressing plate 15 abuts against the lower transmission plate 9 to move the upper pressing die 10 in the direction of the lower pressing die 11.

[0021] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
