Technical Field
[0001] This utility model relates to the field of punching machine technology, and in particular to a self-cleaning punching machine for cable tray connecting piece molds. Background Technology
[0002] Cable tray connecting pieces are used to connect the two ends of a cable tray, making them a continuous whole. This ensures the mechanical strength and stability of the cable tray system and prevents the tray from separating due to cable load or external forces. During the production of cable tray connecting pieces, a punching machine is needed to punch mounting holes for bolt assembly on the surface of the connecting pieces. However, existing punching machines generally have the following problems:
[0003] When using a punching machine to process cable tray connecting pieces made of iron, the upper die of the punching machine moves downward to punch the cable tray connecting pieces in the lower die. The resulting waste material will remain in the lower die, and workers need to clean the waste material before the next punching operation can be carried out.
[0004] In summary, existing punching machines produce waste material that remains in the lower die when punching cable tray connecting pieces, requiring manual cleaning before the next punching operation can proceed. Therefore, we propose a self-cleaning punching machine for cable tray connecting piece molds. Utility Model Content
[0005] In order to solve the technical problems existing in the prior art, the present invention provides a self-cleaning punching machine for cable tray connecting piece molds.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a self-cleaning punching machine for cable tray connecting piece molds, comprising a worktable, a bracket fixedly mounted on the upper surface of the worktable, a hydraulic cylinder fixedly mounted vertically on the upper surface of the bracket, an upper mold fixedly mounted through the output end of the hydraulic cylinder, a support plate fixedly mounted on the upper surface of the worktable, a lower mold adapted to the upper mold fixedly mounted on the upper surface of the support plate, the lower mold being slidably connected to the bracket, a rotating plate being rotatably connected to the surface of the support plate, an electric push rod fixedly mounted on the upper surface of the worktable, a magnet plate fixedly mounted on the output end of the electric push rod, and as punching proceeds, the generated cable tray connecting piece waste is attracted by the magnet plate and falls from the lower mold onto the rotating plate.
[0007] Preferably, a number of telescopic rods are vertically fixedly mounted on the upper surface of the workbench, and the free ends of the telescopic rods are fixedly connected to the magnet plate.
[0008] Preferably, a round rod is horizontally rotatably connected inside the support plate. One end of the round rod is coaxially fixedly fitted with a top plate. A protrusion that abuts against the surface of the top plate is fixedly fitted on the lower surface of the rotating plate. A gear is coaxially fixedly fitted on the other end of the round rod. A T-shaped plate is fixedly fitted on the side wall of the support plate. A rack that meshes with the gear is slidably fitted on the surface of the T-shaped plate. A torsion spring is fitted on the outer circumference of the round rod. The two ends of the torsion spring are fixedly connected to the gear and the support plate, respectively.
[0009] Preferably, a buffer block is fixedly mounted on the upper mold relative to the rack.
[0010] Preferably, a storage box is slidably connected to the workbench relative to the rotating plate.
[0011] Preferably, the side wall of the support plate is provided with a slot with a vertical cross section in the shape of an "L", and the outer wall of the storage box is fixedly fitted with a card block that matches the slot.
[0012] Preferably, two guide plates are fixedly mounted on the upper surface of the rotating plate.
[0013] Compared with the prior art, this utility model provides a self-cleaning punching machine for cable tray connecting piece molds, which has the following beneficial effects:
[0014] (1) In this utility model, during the punching process of the cable tray connecting piece, the waste generated will fall from the lower mold to prevent the waste from remaining on the inner wall of the lower mold and perform self-cleaning. The magnetic plate will attract the waste and make the waste adhere to the surface of the rotating plate, thus avoiding the waste from falling around the workbench.
[0015] (2) By setting components such as top plate, protrusion, rack and gear and torsion spring, when the upper mold moves upward, the torsion spring will drive the gear to rotate by its own torque. The rotation of the gear will drive the round rod to rotate. The rotation of the round rod will drive the top plate to rotate. The rotation of the top plate will squeeze the protrusion. The protrusion will drive the rotating plate to move upward. When the protrusion moves a certain distance, it will move downward due to gravity. The rotating plate will move synchronously. Therefore, as the top plate rotates, the rotating plate will swing back and forth within a certain angle, thereby accelerating the scrap from the surface of the rotating plate.
[0016] (3) By setting up a collection box, the waste will be collected after it slides off the surface of the rotating plate, making it convenient to process the waste in a concentrated manner later. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0025] like Figures 1-5As shown, this utility model provides a self-cleaning punching machine for cable tray connecting piece molds, including a workbench 1. A bracket 2 is fixedly mounted on the upper surface of the workbench 1. A hydraulic cylinder 3 is vertically fixedly mounted on the upper surface of the bracket 2. An upper mold 4 is fixedly mounted through the output end of the hydraulic cylinder 3 via the bracket 2. A support plate 5 is fixedly mounted on the upper surface of the workbench 1. A lower mold 6, which is adapted to the upper mold 4, is fixedly mounted on the upper surface of the support plate 5. The lower mold 6 is slidably connected to the bracket 2. When processing cable tray connecting pieces, the cable tray connecting pieces are placed in the lower mold 6, and then the hydraulic cylinder 4 is controlled to press the upper mold 4. When the output end of the pressure cylinder 3 extends, the upper die 4 moves downward to punch holes in the cable tray connecting piece. The surface of the support plate 5 is rotatably connected to the rotating plate 7. The upper surface of the worktable 1 is fixedly equipped with an electric push rod 8. The output end of the electric push rod 8 is fixedly equipped with a magnet plate 9. Before punching, the output end of the electric push rod 8 is controlled to extend, so that the magnet plate 9 moves upward. At this time, the waste generated will fall from the lower die 6, preventing the waste from remaining on the inner wall of the lower die 6. The magnet plate 9 will attract the waste, so that the waste adheres to the surface of the rotating plate 7, avoiding the waste from spilling around the worktable 1.
[0026] In the above scheme, when the magnet plate 9 moves upward, the electric push rod 8 has difficulty restricting the movement path of the magnet plate 9, which causes the magnet plate 9 to easily deviate and affects the attraction effect of the magnet plate 9 on the waste. Therefore, it is necessary to restrict the movement path of the magnet plate 9. Specifically, several telescopic rods 10 are vertically fixedly mounted on the upper surface of the workbench 1. The free end of the telescopic rod 10 is fixedly connected to the magnet plate 9. When the magnet plate 9 moves upward, it will stretch the telescopic rod 10, and the telescopic rod 10 will restrict the movement path of the magnet plate 9.
[0027] When the waste material slides down the surface of the rotating plate 7, it is easy for the waste material to become stuck and blocked due to the friction between it and the rotating plate 7, resulting in a large accumulation of waste material on the surface of the rotating plate 7. Therefore, it is necessary to speed up the sliding speed of the waste material. In view of the above needs, in this embodiment, a round rod 11 is horizontally rotatably connected inside the support plate 5. One end of the round rod 11 is coaxially fixedly fitted with a top plate 12. A protrusion 22 that abuts against the surface of the top plate 12 is fixedly fitted on the lower surface of the rotating plate 7. A gear 13 is coaxially fixedly fitted on the other end of the round rod 11. A T-shaped plate 14 is fixedly fitted on the side wall of the support plate 5. A rack 15 that meshes with the gear 13 is slidably fitted on the surface of the T-shaped plate 14. A torsion spring 16 is fitted on the outer circumference of the round rod 11. The two ends of the torsion spring 16 are fixedly connected to the gear 13 and the support plate 5, respectively. When the upper mold 4 moves downward... When in motion, the upper mold 4 will squeeze the rack 15. The rack 15 slides down along the surface of the T-shaped plate 14 and drives the gear 13 to rotate. The rotation of the gear 13 will torsion spring 16. When the upper mold 4 moves upward, the output end of the electric push rod 8 is controlled to retract first, so that the magnetic plate 9 no longer attracts waste. The torsion spring 16 will drive the gear 13 to rotate in the opposite direction with its own torque. The rotation of the gear 13 will drive the round rod 11 to rotate. The rotation of the round rod 11 will drive the top plate 12 to rotate. The rotation of the top plate 12 will squeeze the protrusion 22. The protrusion 22 will drive the rotating plate 7 to move upward. After the protrusion 22 moves a certain distance, it will move downward due to gravity. The rotating plate 7 will move synchronously. Therefore, as the top plate 12 rotates, the rotating plate 7 will swing back and forth within a certain angle, thereby accelerating the sliding of waste from the surface of the rotating plate 7.
[0028] When the upper mold 4 contacts the rack 15, the collision force between the upper mold 4 and the rack 15 is relatively large, which makes the rack 15 prone to deformation and damage. Therefore, in this embodiment, a buffer block 17 is fixedly installed at the position of the upper mold 4 relative to the rack 15. The material of the buffer block 17 includes, but is not limited to, rubber material. The buffer block 17 can prevent the upper mold 4 from having a rigid collision with the rack 15, reduce the collision force between the upper mold 4 and the rack 15, and greatly extend the service life of the rack 15.
[0029] In addition, after the waste material slides off the surface of the rotating plate 7, it still needs to be collected manually. Therefore, further facilitating operation is required. Specifically, a storage box 18 is slidably connected to the workbench 1 relative to the rotating plate 7. When the waste material slides off the surface of the rotating plate 7, it will fall into the storage box 18, which will collect the waste material for convenient subsequent centralized processing.
[0030] During the punching process, the surface of the workbench 1 is prone to vibration, which causes the storage box 18 to shift. Therefore, it is necessary to restrict the position of the storage box 18. The side wall of the support plate 5 is provided with a vertical slot 19 with an "L" shaped cross section. The outer wall of the storage box 18 is fixedly equipped with a locking block 20 that matches the slot 19. When the locking block 20 slides into the inner wall of the slot 19, the slot 19 reaches the position of the locking block 20, thereby restricting the position of the storage box 18.
[0031] When the waste material slides off the surface of the rotating plate 7, the distribution range is large, making it inconvenient for the storage box 18 to collect the waste material. Therefore, it is necessary to reduce the distribution range of the waste material. Specifically, two guide plates 21 are fixedly installed on the upper surface of the rotating plate 7. The guide plates 21 can guide the waste material, thereby limiting the distribution range of the waste material after it slides off.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more features.
