[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. Obviously, 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figs. 1-3This utility model provides an embodiment of a punching mechanism for a forging hydraulic press, comprising a base frame 1, a support frame 18 fixedly connected to the rear side of the top of the base frame 1, a hydraulic press body 19 fixedly connected to the inner wall of the support frame 18, a punching head 22 fixedly connected to the bottom of the hydraulic press body 19, a slide plate 21, a first slide rod 20, a support plate 23, and a second slide rod 24 fixedly connected to the bottom side of the outer wall of the hydraulic press body 19, a platform 8 fixedly connected to the middle of the top of the base frame 1, and a bidirectional lead screw 9 rotatably connected to the bottom of the platform 8. The outer wall of the bidirectional lead screw 9 is threaded with two threaded sleeves 10. The top of each threaded sleeve 10 is fixedly connected with a clamping plate 11. The bottom of each threaded sleeve 10 is fixedly connected with a guide plate 14. The bottom of the base frame 1 is fixedly connected with two fixing plates 2. The two fixing plates 2 are connected to a storage box 5 through a slide rail at one end. The storage box 5 is connected to the fixing plate 2 through a fixing block 6, a second magnetic block 7 and a first magnetic block 4. The top of the shelf 8 and the base frame 1 are both provided with through holes. The right end of the base frame 1 is provided with a brush 25 through a hook.
[0024] Specifically, rotating the knob 12 on the right end of the bidirectional lead screw 9, which is fixedly connected to the bidirectional lead screw 9, causes the bidirectional lead screw 9 to rotate. Two threaded sleeves 10 are threadedly connected to the outer wall of the bidirectional lead screw 9. When the bidirectional lead screw 9 rotates, according to the principle of threaded transmission, the two threaded sleeves 10 move along the axial direction of the bidirectional lead screw 9. Due to the special structure of the bidirectional lead screw 9, the two threaded sleeves 10 can move towards or away from each other. A clamping plate 11 is fixedly connected to the top of each threaded sleeve 10, so when the threaded sleeves 10 move, they drive the clamping plate 11 to move synchronously. In this way, the two clamping plates 11 gradually approach each other until the hydraulic press housing 17 is tightly clamped and fixed on the platform 8, ensuring that the hydraulic press housing 17 will not shift during the punching process and guaranteeing the punching accuracy. After punching is completed, rotating the knob 12 in the opposite direction causes the bidirectional lead screw 9 to rotate in the opposite direction, causing the threaded sleeves 10 to move away from each other. The movement causes the clamping plate 11 to loosen its grip on the hydraulic press housing 17. After the hydraulic press housing 17 with punched holes is removed from the platform 8, the brush 25 is removed from the hook on the right end of the base frame 1. The platform 8 has a through groove 13 in the middle. The brush 25 is used to sweep the debris on the platform 8 through the through groove 13 onto the guide plate 14. The guide plate 14 is fixed to the bottom end of the threaded sleeve 10, so that the debris slides down the guide plate 14 under the action of gravity and finally falls into the base frame 1. Storage is carried out in the storage box 5 at the bottom. When there are a lot of debris stored in the storage box 5 and it needs to be cleaned, pull the storage box 5 and remove it along the sliding tenon 3. The debris stored in the storage box 5 is then collected and processed. The punch head 22 is fixed at the bottom of the hydraulic press body 19 and moves downward under the drive of the hydraulic press body 19 to perform punching operation on the hydraulic press housing 17 placed on the platform 8 and clamped and fixed. It is the component that directly completes the punching work.
[0025] Reference Figs. 1-3The storage box 5 has two fixed blocks 6 located on the top sides at both ends. Each fixed block 6 has a second magnetic block 7 fixedly connected to its inner wall. Each fixed plate 2 has a first magnetic block 4 fixedly connected to its inner wall. The second magnetic block 7 and the first magnetic block 4 are attracted by opposite poles. Each fixed plate 2 has a sliding tenon 3 fixedly connected to its adjacent end. Both sliding tenons 3 are located on the inner wall of the storage box 5. The hydraulic press body 19 has a sliding plate 21 and a support plate 23 located on its bottom outer wall. The rear end of the sliding plate 21 is slidably connected to a sliding rod 20. 0 is fixedly connected to the inner wall of the support frame 18. The four corners of the support plate 23 are slidably connected to the slide rod 24. Multiple slide rods 24 are fixedly connected to the top of the base frame 1. The tops of the two guide plates 14 are fixedly connected to the baffles 15. The baffles 15 are slidably connected to the through groove 2 16. The middle of the platform 8 is provided with the through groove 13. The middle of the base frame 1 is provided with the through groove 2 16. The right end of the bidirectional screw 9 is fixedly connected to the knob 12. The two clamping plates 11 are provided with the hydraulic press housing 17 at their close ends.
[0026] Specifically, the rear end of the slide plate 21 is slidably connected to the slide rod 20, which is fixedly connected to the inner wall of the support frame 18. Each of the four corners of the support plate 23 is slidably connected to a slide rod 24, and multiple slide rods 24 are fixedly connected to the top of the base frame 1. When the punch head 22 moves downwards, the support plate 23 moves smoothly along the guide of the slide rods 24, and the slide plate 21 also slides along the slide rods 20, thus ensuring the stability of the punch head 22 during movement, preventing the punch head 22 from shaking, and further improving the punching quality. The storage box 5 is connected to the fixed plate 2 via a magnetic assembly. The magnetic assembly includes fixed blocks 6 located on the top sides of the left and right ends of the storage box 5, with the inner walls of the fixed blocks 6 fixed. A magnetic block 7 is connected to the inner wall of the fixing plate 2, and a magnetic block 4 is fixedly connected to the inner wall of the fixing plate 2. Magnetic block 7 and magnetic block 4 are attracted by opposite poles. A baffle 15 is fixedly connected to the top of the guide plate 14. When the storage box 5 is pulled, the magnetic attraction between magnetic block 7 and magnetic block 4 is canceled. At the same time, a sliding tenon 3 fixedly connected to one end of the fixing plate 2 is set on the inner wall of the storage box 5. The sliding tenon 3 provides a guide for the movement of the storage box 5, making it easy to remove the storage box 5 along the sliding tenon 3. The debris stored in the storage box 5 is centrally processed. When the debris on the shelf 8 is swept onto the guide plate 14 through the through groove 13 by the brush 25, the baffle 15 can prevent the debris from sliding off the guide plate 14 and can also guide the debris.
[0027] Working principle: The hydraulic press housing 17 is placed on the platform 8. Rotating the knob 12 drives the double-acting screw 9 to rotate, which in turn moves the clamping plate 11 via the threaded sleeve 10. The clamping plate 11 clamps and fixes the hydraulic press housing 17. Then, the hydraulic press body 19 is started, causing the punching head 22 to move downwards, thus punching the hydraulic press housing 17. As the punching head 22 moves downwards, the support plate 23 moves along the guide of the sliding rod 24, thus maintaining the stability of the punching head 22's movement. After punching is complete, rotating the knob 12 in the opposite direction releases the clamping of the hydraulic press housing 17. After removing the hydraulic press housing 17, remove the brush 25 and sweep the debris left on the platform 8 through the through groove 13 onto the guide plate 14. Under the action of gravity, the debris falls into the storage box 5 for storage. When punching is needed again, continue to rotate the double-acting screw 9 to drive the clamping plate 11 to clamp the hydraulic press housing 17. At the same time, as the threaded sleeve 10 moves, it will drive the guide plate 14 to move synchronously with the clamping plate 11. After punching is completed, pull the storage box 5 to cancel the magnetic attraction between the magnetic block 2 7 and the magnetic block 1 4. Then, remove the storage box 5 along the sliding tenon 3 to collect and process the debris stored in the storage box 5.
