[0002] A shield is a device that surrounds the source of interference in components, circuits, assemblies, cables, or the entire system to prevent electromagnetic fields from spreading outward. It is widely used in fields such as intelligent communication equipment, automotive electronic equipment, medical equipment, and aerospace equipment.

[0003] Most existing shielding covers are in the form of metal plates during the production process. They need to be cut and bent according to different usage requirements so that they can better fit the specifications of the relevant circuit boards during subsequent installation.

However, because the shielding cover itself is thin and has weak impact resistance, it is easy to break or crack during the stamping and bending process, resulting in the scrapping of the shielding cover and a low yield of bent products. Therefore, improvements are needed. Utility Model Content

[0027] like Figures 1 to 6 As shown, a shield bending device includes a bending module 10 and a bending die base 20. The bending module 10 includes a bending drive 11 and a bending die head 12. The bending drive 11 is connected to the bending die head 12 and drives the bending die head 12 to move in the vertical direction. A bending groove 29 is provided on the bending die base 20. A bending buffer is provided in the bending groove 29. The bending groove 29 is located below the bending die head 12. The bending buffer is used to buffer the bending of the bending die head 12. When bending the shielding cover, the shielding cover to be bent is first placed on the bending die base 20, and then the bending drive 11 drives the bending die head 12 to move towards the bending die base 20. When the bending die head 12 bends the shielding cover, the bending buffer on the bending die base 20 will buffer the impact of the bending die head 12, thereby effectively preventing the shielding cover from breaking or being damaged during processing, and greatly improving the yield of the shielding cover.

[0028] The bending buffer includes two fixed blocks 21 and two mirror-image movable blocks 22. The movable blocks 22 are provided with buffer grooves 26, and buffer elastic members 23 are provided in the buffer grooves 26. One end of the buffer elastic member 23 abuts against the inner wall of the buffer groove 26, and the other end of the buffer elastic member 23 abuts against the fixed blocks 21. In this embodiment, two fixed blocks 21 and two mirror-image movable blocks 22, along with a buffer elastic element 23, are used to buffer the impact force on the bending die head 12. When the shield is bent, the movable block 22 comes into contact with the bending die head 12 and slowly moves backward in the bending groove 29 due to the impact force, thereby buffering the bending die head 12. During the backward movement of the movable block 22, the buffer elastic element 23 located in the buffer groove 26 cooperates with the fixed block 21 to compress the buffer elastic element 23. This facilitates the release of the compressive potential energy of the buffer elastic element 23 after the bending die head 12 and the movable block 22 are released, allowing the movable block 22 to reset, so as to buffer the next bending.

[0029] The movable block 22 includes a first connecting block 24 and a second connecting block 25, which are integrally formed. The first connecting block 24 is L-shaped and has a connecting platform. The second connecting block 25 is located on the connecting platform, and the buffer groove 26 is located on the first connecting block 24. In this embodiment, the movable block 22 is formed by the first connecting block 24 and the second connecting block 25. The connecting platform is provided on the first connecting block 24, and the second connecting block 25 cooperates with the first connecting block 24 to achieve buffering of the bending die head 12.

[0030] The first connecting block 24 includes a first assembly part and a second assembly part, which are arranged perpendicularly to each other. The second assembly part is located at the front end of the first assembly part. A buffer groove 26 is formed at the rear end of the first assembly part, and a buffer inclined surface 27 is provided on the second assembly part. In this embodiment, the buffer groove 26 is provided at the rear end of the first assembly part to facilitate connection with the buffer elastic member 23, and the buffer inclined surface 27 is provided at the upper end of the second assembly part to improve the buffering efficiency when in contact with the bending die head 12.

[0031] The second connecting block 25 is provided with a fixing slot 28. In this embodiment, two opposing second connecting blocks 25 form a material guiding channel, so that the shield to be bent can enter the bending groove 29 through the material guiding channel. At the same time, the fixing slot 28 is provided on the second connecting block 25. The fixing slot 28 is located on the inner wall of the material guiding channel, so that the part of the shield located in the material guiding channel can be fixed and locked through the fixing slot 28, thereby improving the stability of the shield during bending.

[0032] The bending drive component 11 also includes a bending frame 13, on which a fixing plate 14 is provided. The fixing plate 14 has a first fixing surface and a second fixing surface. The bending drive component 11 is disposed on the first fixing surface, and a transmission block 19 is provided on the driving end of the bending drive component 11. The bending die 12 is movably disposed on the second fixing surface and is connected to the transmission block 19. The bending drive component 11 drives the bending die 12 to move vertically through the transmission block 19. In this embodiment, a fixing plate 14 is provided on the bending frame 13. By setting the bending drive component 11 on the first fixing surface of the fixing plate 14 and the bending die 12 on the second fixing surface of the fixing plate 14, it is easier to position the bending die 12, thereby improving bending efficiency.

[0033] A bending guide rail 15 is provided on the second fixed surface, and a bending slider 16 is provided on the bending guide rail 15. A mounting plate 17 is connected to the bending slider 16, and the mounting plate 17 is connected to the transmission block 19. In this embodiment, the bending guide rail 15 and the bending slider 16 are provided on the second fixed surface. By providing the mounting plate 17 on the bending slider 16, and by connecting the mounting plate 17 with the transmission block 19, the stability during bending is improved.

[0034] An auxiliary mounting plate 18 is provided on the mounting plate 17. The auxiliary mounting plate 18 is disposed on the second fixed surface to form an auxiliary fixing hole on the second fixed surface. The bending die 12 passes through the auxiliary fixing hole and is connected to the transmission block 19. In this embodiment, by providing an auxiliary mounting plate 18 on the mounting plate 17, the mounting plate 17 and the auxiliary mounting plate 18 cooperate to form an auxiliary fixing hole, and the bending die 12 is located in the auxiliary fixing hole, which further improves the stability of the bending die 12 during bending.

[0035] A first fixing groove is provided on the side of the bending die 12 facing the transmission block 19. A second fixing groove corresponding to the first fixing groove is provided on the transmission block 19. A buffer spring 122 is provided in the first fixing groove, and the buffer spring 122 is connected to the first fixing groove and the second fixing groove respectively. In this embodiment, by connecting the buffer spring 122 to the bending die 12 and the transmission block 19 respectively, the buffering effect of the bending die 12 during bending is further improved, avoiding damage to the shielding cover during bending.

[0036] The bending die 12 includes a bending main block, on which a connecting part and a bending part are provided. The connecting part is used to connect with the bending drive component 11. The bending part is provided with a bending head 121, which is located at the lower end of the bending main block. The thickness of the bending head 121 is less than the thickness of the bending main block, and the bending head 121 is integrally formed with the bending main block. In this embodiment, by providing the bending head 121 on the bending main block, the shielding cover is precisely bent by the bending head 121, thereby improving the bending accuracy.
