[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figures 1-4 A voice coil skeleton punching die includes a connecting plate 1 and a guide frame 3. A mounting plate 2 is bolted to one side of the connecting plate 1. A connecting assembly is provided between the mounting plate 2 and the guide frame 3. A mounting bracket 8 is bolted to one side of the connecting plate 1. A baffle 9 is bolted to the bottom outer wall of the mounting plate 2. A guide groove 4 is formed inside the guide frame 3. After punching, the mounting plate 2 is moved in the reverse direction until the baffle 9 no longer obstructs the guide groove 4. At this time, the punched voice coil skeleton moves downward along the guide groove 4 under its own gravity, facilitating the collection of the punched voice coil skeleton. Multiple limiting posts 13 are bolted to one side of the connecting plate 1, and the limiting posts 13 are fixed to the mounting plate 2. A bolted section is fixed inside the limiting posts 13. Multiple punched posts 14 are provided. The mounting plate 2 has multiple positioning holes 12 inside, and the punched posts 14 are slidably connected to the positioning holes 12. The guide frame 3 has multiple limiting holes 15 inside, and the punched posts 14 are slidably connected to the limiting holes 15. The limiting holes 15 are connected to their corresponding positioning holes 12. The guide frame 3 has multiple discharge ports 17 on its outer side. The punched posts 14 pass through the guide groove 4 and the discharge ports 17, placing the voice coil skeleton inside the guide groove 4. At this time, the bottom of the voice coil skeleton contacts the baffle 9. Then, the connecting plate 1 is pushed, causing the mounting plate 2 to move the punched posts 14 along the positioning holes 12 and the limiting holes 15, so that the conical head 16 on the punched posts 14 punches the voice coil skeleton in the guide groove 4 and passes through the discharge port 17.
[0024] In this utility model, it should be noted that the connecting assembly includes multiple guide rods 11, which are respectively fixed to both sides of the mounting plate 2 by bolts. Two guide grooves 10 are provided on both sides of the guide frame 3, and the guide rods 11 are slidably connected to the guide grooves 10. Through the cooperation of the guide rods 11 and the guide grooves 10, a stable connection is achieved between the mounting plate 2 and the guide frame 3. Simultaneously, the mounting plate 2 is guided, allowing it to move stably and preventing the punched column 14 from tilting during movement. The top of the guide groove 4 has a slope 6, which facilitates the placement of the voice coil frame into the guide groove 4. One end of the punched column 14 is integrally formed with a tapered head 16. The conical head 16 makes the punching effect of the device more efficient. The guide trough 4 is connected to the limiting hole 15 and the discharge port 17. A collection box 7 is provided on one side of the outer wall of the guide frame 3. The collection box 7 can collect the waste material generated after punching, and prevent the waste material from falling directly to the ground and causing environmental mess. Multiple clips 5 are fixed on one side of the outer wall of the guide frame 3 by bolts. Two slots 18 are opened on both sides of the collection box 7, and the clips 5 are engaged with the corresponding slots 18. Through the cooperation of the slots 18 and the clips 5, it is convenient for the staff to install and disassemble the collection box 7, and thus convenient for the staff to centrally process the collected waste material. The baffle 9 can cover the bottom of the guide trough 4.
[0025] Working principle: When punching is required for the voice coil skeleton, the voice coil skeleton is first placed inside the guide groove 4. At this time, the bottom of the voice coil skeleton is in contact with the baffle 9. Then, the connecting plate 1 is pushed, so that the mounting plate 2 drives the punching column 14 to move along the positioning hole 12 and the limiting hole 15. The conical head 16 on the punching column 14 punches the voice coil skeleton in the guide groove 4 and passes through the discharge port 17. At the same time, the mounting plate 2 moves, so that the guide rod 11 moves along the guide groove 10, thereby making the movement of the mounting plate 2 smoother and more stable. Then, the waste generated by punching falls into the collection box 7. After punching is completed, the mounting plate 2 is moved in the opposite direction until the baffle 9 no longer obstructs the guide groove 4. At this time, the punched voice coil skeleton moves downward along the guide groove 4 under its own gravity, which facilitates the collection of the punched voice coil skeleton.
[0026] Finally, it should be noted that those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
