Description

Technical Field

[0001] This utility model relates to the technical field of busbar trunking processing equipment, and in particular to a bending machine for producing multi-angle busbar trunking. Background Technology

[0002] Busbar trunking, as a high-efficiency power transmission equipment, is widely used in power supply and distribution systems in high-rise buildings, industrial plants and other places. In the manufacturing process of busbar trunking, the bending process is the key link that determines the final shape and installation adaptability of the product. In particular, for busbar trunking that needs to adapt to complex wiring paths, it is often necessary to perform multi-angle and high-precision bending processing on its conductor copper busbars or aluminum busbars.

[0003] Existing busbar bending equipment has certain limitations in practical use. Traditional bending machines mostly use unidirectional pressure plates or manual clamps to fix the plates. When dealing with busbar plates of different thicknesses, it is often necessary to manually adjust the clamp height or change the mold repeatedly. This is not only cumbersome and time-consuming, but also makes it difficult to ensure the precise automatic alignment of the plates in the vertical direction, resulting in uneven distribution of clamping force and affecting bending accuracy. In addition, conventional bending mechanisms are mostly fixed-angle stamping structures. If it is necessary to change the bending angle or bending direction, it is usually necessary to reposition the workpiece or adjust complex mechanical limits. It is difficult to achieve continuous and flexible multi-angle wrap-around bending, resulting in low production efficiency and poor equipment versatility.

[0004] Therefore, this utility model proposes a bending machine for producing multi-angle folded busbar trunking to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems existing in the busbar bending equipment, such as low clamping efficiency, cumbersome manual operation and difficulty in achieving automatic centering and fixing of the sheet metal, as well as limited bending angle adjustment and low production efficiency due to frequent workpiece position adjustment required for bending in a single direction, this utility model aims to provide a multi-angle bending machine for busbar production with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a bending machine for producing multi-angle folded busbar trunking, comprising: a main body, a motor one fixed to the top of the outer wall of the main body, a bidirectional threaded rod fixedly connected to the output end of the motor one, an upper lifting plate and a lower lifting plate threadedly connected to the outer wall of the bidirectional threaded rod, a pressure block fixedly connected to the bottom of the outer wall of the upper lifting plate; and a bending block, a rotating ring, a gear ring, a second motor, a gear shaft, and a bending column.

[0007] The bending block is fixedly connected to the top of the outer wall of the lower lifting plate, the rotating ring is rotatably connected to the outer wall of the bending block, the gear ring is fixedly connected to the middle of the outer wall of the rotating ring, the second motor is fixedly connected to the inner wall of the lower lifting plate, the gear shaft is fixedly connected to the output end of the second motor, the gear shaft meshes with the gear ring, and the bending column is fixedly connected to the top of the outer wall of the rotating ring.

[0008] Furthermore, the upper lifting plate and the lower lifting plate achieve synchronous opposite lifting through the rotation of the bidirectional threaded rod. The pressure block and the bending block are used to clamp the material plate located therebetween. The second motor drives the rotating ring and the bending column to rotate around the bending block through the cooperation of the gear shaft and the gear ring.

[0009] Preferably, a limiting rod is fixedly connected to the middle of the outer wall of the main body, and the upper lifting plate and the lower lifting plate are slidably connected to the outer wall of the limiting rod. The limiting rod passes through the upper lifting plate and the lower lifting plate to restrict their rotation and guide them to rise and fall smoothly in the vertical direction.

[0010] Preferably, the threads at both ends of the bidirectional threaded rod are opposite, and the upper lifting plate and the lower lifting plate achieve synchronous opposite lifting through the bidirectional threaded rod. The bidirectional threaded rod is driven to rotate by the motor, thereby causing the upper lifting plate and the lower lifting plate to move closer to or further away from each other.

[0011] Preferably, a material plate is slidably connected to the middle of the outer wall of the main body. The material plate is located in the middle of the outer wall of the bending block. The material plate is placed on the main body as a workpiece to be processed and can be conveyed to the processing area between the pressure block and the bending block.

[0012] Preferably, the pressing block engages with the lower lifting plate, and the pressing block is used to press the material plate. The bottom surface of the pressing block cooperates with the top surface of the bending block to fix the material plate in a predetermined position and prevent it from shifting during processing.

[0013] Preferably, a groove is provided in the middle of the outer wall of the bending column. The groove is used to prevent the material plate from deviating from the bending trajectory during the bending process. The groove is arranged around the circumference of the bending column and can accommodate the edge of the material plate, limiting its vertical jump.

[0014] Preferably, there are two motors, which are fixedly connected to the top of the outer wall of the main body. The two motors are symmetrically distributed and drive the corresponding bidirectional threaded rods to provide more balanced lifting power.

[0015] Preferably, there are two bending columns, which are fixedly connected to the top of the outer wall of the rotating ring. The two bending columns are symmetrically distributed and rotate together with the rotating ring to apply force to the material plate in different directions.

[0016] Preferably, the second motor drives the gear shaft to rotate, which in turn drives the gear ring and the rotating ring to rotate in the middle of the outer wall of the bending block. The second motor is integrated into the lower lifting plate and rises and falls together with the lower lifting plate, simplifying the transmission structure.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of low clamping efficiency, cumbersome manual operation, and difficulty in automatically centering and fixing plates in the existing busbar bending equipment by setting a motor-driven bidirectional threaded rod to drive the upper and lower lifting plates to lift in opposite directions synchronously. With the mutual locking of the pressure block and bending block, it achieves the effect of quickly, stably and automatically centering and clamping plates of different thicknesses, effectively preventing the workpiece from shifting or deflecting during processing.

[0018] 2. This utility model integrates a motor-driven gear shaft and gear ring inside the lower lifting plate, thereby driving the rotating ring and bending column to rotate around the centrally fixed bending block. This solves the problems of limited bending angle adjustment and frequent workpiece position adjustment required for bending in a single direction in existing bending devices. It achieves the effect of flexible multi-angle and multi-directional circumferential bending, and the transmission structure is compact, improving the processing adaptability and production efficiency of the equipment.

[0019] 3. This utility model solves the problems of the prior art where the sheet metal easily deviates from the predetermined trajectory during strong bending and the lifting component easily rotates with the screw, by opening a groove on the outer wall of the bending column and setting a limiting rod through the lifting component on the main body. It effectively restricts the vertical movement of the sheet metal, ensures that the bending lines are straight and beautiful, and ensures that the overall mechanical action is precise and stable, thus significantly improving the yield of finished products.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0023] Please refer to Figures 1 to 4 This utility model provides a bending machine for producing multi-angle busbar trunking, which aims to solve the problems of low production efficiency and unstable finished product quality caused by difficulties in automatic centering and clamping of sheet metal during busbar trunking processing and insufficient flexibility in adjusting the bending angle in the prior art. Figure 1 and Figure 2 As shown, the bending machine for producing multi-angle busbar trunking includes a main body 1, which serves as the main support structure for installing various functional components. Two motors 2 are fixedly connected to the top of the outer wall of the main body 1 by bolts. The motors 2 are symmetrically distributed on the top of the outer wall of the main body 1 and serve as the drive source for the entire lifting device. A bidirectional threaded rod 3 is fixedly connected to the output end of the motor 2. The bidirectional threaded rod 3 is vertically arranged and extends into the interior of the main body 1. An upper lifting plate 4 is threadedly connected to the upper end of the outer wall of the bidirectional threaded rod 3, and a lower lifting plate 7 is threadedly connected to the lower end of the outer wall of the bidirectional threaded rod 3. The threads at both ends of the bidirectional threaded rod 3 are arranged in opposite directions. When the motor 2 drives the bidirectional threaded rod 3 to rotate, it can drive the upper lifting plate 4 and the lower lifting plate 7 to move synchronously in opposite directions along the vertical direction, thereby realizing the rapid clamping and release of the workpiece.

[0024] To ensure the stability and verticality of the lifting process, a limiting rod 6 is fixedly connected to the middle of the outer wall of the main body 1. The limiting rod 6 vertically passes through the upper lifting plate 4 and the lower lifting plate 7. The upper lifting plate 4 and the lower lifting plate 7 are slidably connected to the outer wall of the limiting rod 6 through sliding holes. The limiting rod 6 can effectively restrict the upper lifting plate 4 and the lower lifting plate 7 from rotating with the bidirectional threaded rod 3, ensuring stable and reliable clamping action and preventing mechanical jamming. A pressure block 5 is fixedly connected to the bottom of the outer wall of the upper lifting plate 4 by welding. The bottom surface of the pressure block 5 is designed to be flat and is used to press the material to be processed downward in the closed state. A material plate 15 is slidably connected to the middle of the outer wall of the main body 1. The material plate 15, as the object to be processed, is located directly below the pressure block 5. When the upper lifting plate 4 descends and the lower lifting plate 7 rises, the pressure block 5 and the lower lifting plate 7 cooperate to firmly lock the material plate 15 in the processing position to prevent displacement during bending.

[0025] To solve the aforementioned technical challenges of multi-angle bending, the core of the technical solution in this embodiment lies in the bending actuator integrated on the lower lifting plate 7. This bending actuator forms an organic linkage with the main body 1 and the material pressing system. Please refer to the following for details. Figure 2 and Figure 3 The core structure is described in detail below. A bending block 8 is fixedly connected to the center of the top of the outer wall of the lower lifting plate 7. The bending block 8 serves as the fixed fulcrum and core of the mold for bending operations. Its shape is adapted to the bending radius of the busbar to be processed. A rotating ring 9 is rotatably connected to the middle of the outer wall of the bending block 8. The rotating ring 9 can rotate freely around the bending block 8 by 360 degrees, providing a basic motion trajectory for multi-angle bending. A gear ring 10 is fixedly connected to the middle of the outer wall of the rotating ring 9 by a key connection or integral molding. The gear ring 10 serves as the key medium for power transmission. The outer circumference of the gear ring 10 is covered with precision gear teeth.

[0026] Meanwhile, in order to drive the rotating ring 9 to rotate precisely, an installation cavity is provided on the inner wall of the lower lifting plate 7. A second motor 11 is fixedly connected to the installation cavity by bolts. The second motor 11 serves as an independent power source for the bending action and moves up and down synchronously with the lower lifting plate 7. The output end of the second motor 11 passes vertically upward through the top surface of the lower lifting plate 7 and is fixedly connected to a gear shaft 12. The gear shaft 12 is located on one side of the gear ring 10 and is tightly meshed with the outer circumferential teeth of the gear ring 10. When the second motor 11 starts, it drives the gear shaft 12 to rotate, which in turn drives the gear ring 10 to rotate, thereby driving the rotating ring 9 to rotate around the bending block 8. This gear transmission structure ensures sufficient torque output and smooth transmission without slippage when bending high-strength busbar grooves.

[0027] Two bending columns 13 are symmetrically fixedly connected to the top of the outer wall of the rotating ring 9. When the bending columns 13 revolve with the rotating ring 9, they apply a lateral thrust to the material plate 15, forcing the material plate 15 to bend around the bending block 8. A groove 14 is provided in the middle of the outer wall of the bending column 13 along the circumferential direction. The cross-sectional shape of the groove 14 matches the edge shape of the material plate 15. During the bending process, the edge of the material plate 15 is embedded in the groove 14. The groove 14 can effectively restrict the vertical movement of the material plate 15 and prevent the material plate 15 from deviating from the bending trajectory after being subjected to force, thus ensuring the consistency and safety of the bending formation.

[0028] As a preferred embodiment, in order to improve the support stability and guiding accuracy of the main body 1 for the lifting component, please refer to... Figure 1 and Figure 2 The limiting rod 6, which is welded and fixed in the middle of the outer wall of the main body 1, is preferably a high-strength cylindrical steel rod. The surface of the limiting rod 6 is precision ground. Self-lubricating bearings or copper sleeves are embedded in the corresponding through holes on the upper lifting plate 4 and the lower lifting plate 7. The self-lubricating bearings or copper sleeves are sleeved on the outer wall of the limiting rod 6. Through this kind of cooperation, mechanical clearance is eliminated while reducing sliding friction resistance, ensuring that the upper lifting plate 4 and the lower lifting plate 7 can maintain extremely high coaxiality and stability under the drive of the bidirectional threaded rod 3, effectively avoiding jamming caused by off-center load.

[0029] As another preferred embodiment, in order to enhance the transmission efficiency of the bidirectional threaded rod 3 and realize the synchronous reverse motion function, the bidirectional threaded rod 3 adopts a trapezoidal thread design. The trapezoidal thread has the characteristics of strong load-bearing capacity and high transmission accuracy. The upper half of the bidirectional threaded rod 3 is machined as a right-hand thread, and the lower half is machined as a left-hand thread, or vice versa. The screw holes inside the upper lifting plate 4 and the lower lifting plate 7 are respectively tapped with internal threads that match the corresponding section threads. This design allows the unidirectional rotation of a single motor 2 to be converted into the linear motion of the two components in opposite directions or in opposite directions, which greatly simplifies the control logic and mechanical structure.

[0030] In another preferred embodiment, to prevent the material plate 15 from accidentally falling off during the bending process and to ensure accurate bending position, the groove 14 on the outer wall of the bending column 13 is preferably a U-shaped groove or a V-shaped groove structure. The opening size of the groove 14 is slightly larger than the thickness of the material plate 15, and the inner wall of the groove 14 is chamfered and polished to reduce scratches on the surface of the material plate 15. At the same time, the installation position of the bending column 13 on the rotating ring 9 can be finely adjusted according to the bending radius requirements of different specifications of busbar grooves. For example, the position can be switched through elongated holes or multiple sets of mounting holes, or the bending column 13 itself can be designed as a rotatable roller structure to change sliding friction to rolling friction, further reducing bending resistance and protecting the surface quality of the workpiece.

[0031] Working principle: In the initial state, the upper lifting plate 4 and the lower lifting plate 7 are in a separated position. The operator places the material plate 15 to be processed on the material plate 15 support structure in the middle of the main body 1 and pushes it into the bending station so that the part of the material plate 15 to be bent is located in the middle of the outer wall of the bending block 8. When it is necessary to fix and clamp the material plate 15, the two motors 1-2 located at the top of the main body 1 are started. The motors 1-2 drive the bidirectional threaded rod 3 connected to it to start rotating. Since the two ends of the bidirectional threaded rod 3 are respectively engraved with threads of opposite directions, and the upper lifting plate 4 is threaded to the upper end of the bidirectional threaded rod 3 and the lower lifting plate 7 is threaded to the lower end of the bidirectional threaded rod 3, as the bidirectional threaded rod 3 rotates, the upper lifting plate 4 and the lower lifting plate 7 move in opposite directions. The lifting plate 7 will move synchronously in opposite directions along the axial direction of the bidirectional threaded rod 3, that is, the upper lifting plate 4 moves downward and the lower lifting plate 7 moves upward. During this process, the limiting rod 6 in the middle of the main body 1 passes through the guide holes of the upper lifting plate 4 and the lower lifting plate 7, which restricts the degree of freedom of the upper lifting plate 4 and the lower lifting plate 7 to rotate with the rod, forcing them to only make a smooth linear lifting and lowering motion along the limiting rod 6 until the pressure block 5 at the bottom of the upper lifting plate 4 and the bending block 8 at the top of the lower lifting plate 7 are completely closed, tightly pressing the material plate 15 in the middle. The bottom surface of the pressure block 5 contacts the upper surface of the material plate 15, and the lower lifting plate 7 drives the top surface of the bending block 8 to contact the lower surface of the material plate 15. The mechanical locking force effectively prevents the material plate 15 from shifting or warping during subsequent processing. Once the material plate 15 is securely clamped, it enters the bending and forming stage. At this time, the second motor 11 installed inside the lower lifting plate 7 is activated. The second motor 11 drives the gear shaft 12 to rotate. The gear shaft 12 drives the outer gear ring 10 to rotate through gear tooth meshing. Since the gear ring 10 is fixedly connected to the rotating ring 9, and the rotating ring 9 is rotatably connected to the outer wall of the bending block 8, the gear ring 10 drives the rotating ring 9 to rotate around the fixed bending block 8. The two bending columns 13 fixed at the top of the rotating ring 9 also revolve around the same point. When the bending columns 13 rotate to contact the edge of the material plate 15, the outer edge of the bending columns 13... The groove 14 in the middle of the wall engages with the side of the material plate 15. As the rotating ring 9 continues to rotate, the bending column 13 applies a lateral thrust, forcing the material plate 15 to undergo plastic deformation around the centrally fixed bending block 8. The operator can flexibly achieve precise bending in different directions and angles to the left or right by controlling the rotation direction and angle of the second motor 11. The design of the groove 14 restricts the vertical movement of the material plate 15 throughout the process, ensuring that the bending lines are straight and beautiful. After processing, the second motor 11 reverses and resets, and the first motor 2 reverses and drives the upper and lower lifting plates 7 to separate, so that the finished product can be taken out.
