[0003] In the manufacturing process of distribution boxes, a bending device is required to bend the cut sheet metal according to the design requirements to form the outer shell structure of the distribution box. However, the existing bending device still has shortcomings in actual use. Because there is no corresponding pressing mechanism at the bending point of the distribution box sheet metal, the sheet metal is prone to warping due to the extrusion of the mold during the bending process, which affects the bending effect. Therefore, this needs to be improved. Utility Model Content

The outer surface of the lead screw is threadedly sleeved on the inner surface of the rectangular block. Limit grooves are respectively opened at the front and rear ends of the fixing frame, and limit blocks are movably sleeved on the top of the inside of the limit grooves. The outer surface of the limit blocks is fixedly connected to the outer surface of the pressure plate.

[0006] As a preferred embodiment of this utility model, a lower mold is fixedly installed on the right side of the top of the operating table, the left end of the lower mold is movably connected to the right end of the placement table, and brackets are fixedly installed on the right ends of both the front and rear ends of the operating table, with the bottom of the inner walls on both the front and rear sides of the brackets movably connected to the front and rear ends of the lower mold.

[0007] As a preferred embodiment of this utility model, a pneumatic cylinder is fixedly installed at the middle of the top of the bracket. The bottom end of the pneumatic cylinder passes through the bracket and extends into the interior of the bracket, and an upper mold is fixedly installed thereon. The outer surface of the upper mold and the inner surface of the bracket are movably sleeved together. Limiting rods are movably sleeved on the front and rear sides of the top of the bracket, and the bottom end of the limiting rod passes through the bracket and extends into the interior of the bracket, and is fixedly connected to the top of the upper mold.

[0008] As a preferred embodiment of this utility model, guide plates are movably sleeved on the front and rear sides of the top center of the placement platform, and there are two guide plates. Each of the two guide plates has a double threaded rod threaded inside. The front and rear ends of the double threaded rod pass through the placement platform and extend to the outside of the placement platform, and a handle is fixedly sleeved on them. The outer surface of the handle is movably connected to the outer surface of the placement platform.

[0009] As a preferred embodiment of this utility model, a top frame is movably fitted inside the right end of the operating table. The top end of the top frame passes through the operating table and the placement table and extends to the top of the placement table. A cylinder is fixedly fitted inside the middle of the top frame. A fixing block is movably fitted on the outer surface of the cylinder. The front and rear ends of the fixing block are movably connected to the front and rear inner walls of the top frame, respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model includes a pressure plate, an inclined plate, a rectangular block, a first motor, and a lead screw. When the first motor is started, the lead screw will rotate. Since the outer surface of the lead screw and the inner surface of the rectangular block are threaded together, the rectangular block will move one end of the inclined plate as the lead screw rotates. This causes the other end of the inclined plate to exert a pushing force on the pressure plate, pushing the pressure plate downward along the inner surface of the fixed frame to press the distribution box plate. This prevents the distribution box plate from warping during bending, which would affect the bending effect.

[0014] 2. This utility model is designed with a top frame, a dual-axis motor, a rotating shaft, a rotating rod, and a round rod. When the dual-axis motor is started, the rotating shaft will drive the rotating rod to rotate. Since the inner surface of the rotating rod and the outer surface of the round rod are movably connected, as the rotating rod rotates, the inner wall of the rotating rod will generate a thrust on the outer surface of the round rod, pushing the round rod and the top frame upward to lift the distribution box plate, thereby preventing the distribution box plate from being adsorbed on the top of the placement platform and making it inconvenient to remove.

[0021] 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.

[0022] like Figures 1 to 5As shown, this utility model provides a bending device for distribution box plates, including a support leg 1. An operating platform 2 is fixedly installed on the top of the support leg 1. A placement platform 3 is fixedly installed on the top of the operating platform 2. Fixing frames 4 are fixedly installed on the right sides of both the front and rear ends of the operating platform 2. The bottom of the inner walls of the front and rear sides of the fixing frames 4 are movably connected to the front and rear ends of the placement platform 3, respectively. A pressure plate 5 is movably sleeved on the top of the inside of the fixing frame 4. An inclined plate 6 is hinged to the middle of the top of the pressure plate 5. A rectangular block 7 is hinged to the other end of the inclined plate 6. The top of the rectangular block 7 is connected to the fixed plate 3. The rear side of the top of the inner surface of the fixed frame 4 is movably connected. The top of the rear end of the fixed frame 4 is fixedly installed with a first motor 8. The other end of the output shaft of the first motor 8 is fixedly sleeved with a lead screw 9. The front end of the lead screw 9 passes through the fixed frame 4 and the rectangular block 7 and extends to the front of the fixed frame 4. The outer surface of the lead screw 9 and the inner surface of the rectangular block 7 are threaded together. Limiting grooves 10 are opened at the front and rear ends of the fixed frame 4 respectively. The top of the inside of the limiting groove 10 is movably sleeved with a limiting block 11. The outer surface of the limiting block 11 is fixedly connected to the outer surface of the pressure plate 5.

[0023] When the first motor 8 starts, the lead screw 9 will rotate. Since the lead screw 9 and the rectangular block 7 are threaded together, the rectangular block 7 will move along the top of the inner surface of the fixed frame 4 as the lead screw 9 rotates. Since the upper and lower ends of the inclined plate 6 are hinged to the rectangular block 7 and the pressure plate 5 respectively, the inclined plate 6 will move along with the rectangular block 7 as it moves. This will cause the other end of the inclined plate 6 to exert a pushing force on the pressure plate 5, pushing the pressure plate 5 towards the placement platform 3. In this way, the pressure plate 5 can be used to press the distribution box plate tightly, thereby preventing it from warping.

[0024] The lower mold 12 is fixedly installed on the right side of the top of the operating table 2. The left end of the lower mold 12 is movably connected to the right end of the placement table 3. The right ends of both the front and rear ends of the operating table 2 are fixedly installed with brackets 13. The bottom of the inner walls on both the front and rear sides of the brackets 13 are movably connected to the front and rear ends of the lower mold 12.

[0025] The bracket 13 provides support, while the lower mold 12 facilitates the bending of the distribution box sheet metal.

[0026] A pneumatic cylinder 14 is fixedly installed at the middle of the top of the bracket 13. The bottom end of the pneumatic cylinder 14 passes through the bracket 13 and extends into the interior of the bracket 13, and an upper mold 15 is fixedly installed thereon. The outer surface of the upper mold 15 is movably sleeved with the inner surface of the bracket 13. Limiting rods 16 are movably sleeved on the front and rear sides of the top of the bracket 13, respectively. The bottom end of the limiting rod 16 passes through the bracket 13 and extends into the interior of the bracket 13, and is fixedly connected to the top of the upper mold 15.

[0027] When the pneumatic cylinder 14 is activated, the upper mold 15 will move along the inner surface of the bracket 13 toward the lower mold 12, thereby cooperating with the lower mold 12 to complete the bending of the distribution box plate.

[0028] Among them, guide plates 17 are movably sleeved on the front and rear sides of the top center of the placement platform 3. There are two guide plates 17. The interior of each guide plate 17 is threaded with a double threaded rod 18. The front and rear ends of the double threaded rod 18 pass through the placement platform 3 and extend to the outside of the placement platform 3, and are fixedly sleeved with handles 19. The outer surface of the handles 19 is movably connected to the outer surface of the placement platform 3.

[0029] When the handle 19 is turned, the double threaded rod 18 will rotate, which will cause the guide plate 17, which is threadedly connected to the double threaded rod 18, to move, thereby guiding the distribution box plate and preventing it from tilting.

[0030] The top frame 20 is movably sleeved inside the right end of the operating table 2. The top of the top frame 20 passes through the operating table 2 and the placement table 3 and extends to the top of the placement table 3. A cylinder 21 is fixedly sleeved in the middle of the inside of the top frame 20. A fixing block 22 is movably sleeved on the outer surface of the cylinder 21. The front and rear ends of the fixing block 22 are movably connected to the front and rear inner walls of the top frame 20, respectively. The left and right ends of the fixing block 22 are fixedly connected to the left and right inner walls of the operating table 2, respectively.

[0031] The presence of the cylinder 21 and the fixing block 22 restricts the movement of the top frame 20, while the presence of the top frame 20 facilitates the lifting of the distribution box plate.

[0032] Among them, a dual-axis motor 23 is fixedly installed in the middle of the bottom of the operating table 2, and a rotating shaft 24 is fixedly sleeved on the other end of the output shaft of the dual-axis motor 23.

[0033] When the dual-axis motor 23 is started, it will cause the rotating shaft 24 to rotate.

[0034] Among them, a rotating rod 25 is fixedly sleeved on the outer surface of the rotating shaft 24, and a round rod 26 is movably sleeved on the right side inside the rotating rod 25. The outer surface of the round rod 26 is fixedly connected to the outer surface of the top frame 20.

[0035] When the rotating shaft 24 drives the rotating rod 25 to rotate, the inner surface of the rotating rod 25 will exert a thrust on the outer surface of the round rod 26, pushing the round rod 26 and the top frame 20 to move.

[0036] Working principle and usage process of this utility model:

[0037] In use, the operator first rotates handle 19 according to the specifications of the distribution box plate, causing the double threaded rod 18 to rotate. This causes the two guide plates 17, which are threaded onto the outer surface of the double threaded rod 18, to move towards each other until the distance between the two guide plates 17 matches the distribution box plate. Then, the operator places the distribution box plate between the two guide plates 17 and aligns the turning point of the distribution box plate with the lower mold 12 and the upper mold 15. The operator then starts the first motor 8, causing the lead screw 9 to rotate. This causes the rectangular block 7, which is threaded onto the outer surface of the lead screw 9, to move along with one end of the inclined plate 6. This causes the other end of the inclined plate 6 to exert a pushing force on the pressure plate 5, pushing the pressure plate 5 downward and pressing the distribution box plate. Finally, the operator starts the pneumatic cylinder 14, causing the upper mold 15 to move towards the lower mold 12, and begins bending the distribution box plate. This helps prevent the distribution box plate from warping during bending, thus affecting the bending effect.

[0038] After bending is completed, the operator starts the dual-axis motor 23, which causes the rotating shaft 24 to drive the rotating rod 25 to rotate. Since the round rod 26 is movably sleeved inside the rotating rod 25, as the rotating rod 25 rotates, the inner surface of the rotating rod 25 will generate a thrust on the outer surface of the round rod 26, pushing the round rod 26 and the top frame 20 upward along the outer surface of the fixed block 22, thereby lifting the distribution box plate. This prevents the distribution box plate from being stuck to the top of the placement platform 3 and making it inconvenient to remove, thus improving the convenience of removing the distribution box plate.
