Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of wire clamp bending machines, specifically to a wire clamp bending machine with an adjustable bending radius. Background Technology

[0002] In power engineering and communication facility construction, guy wire clamps are key components for fixing cables, and their bending accuracy directly affects the stability of the line. However, traditional guy wire clamp bending machines have significant technical bottlenecks in actual production, especially the inconvenience of adjusting the bending radius and the difficulty of material cutting.

[0003] Existing bending equipment mostly uses fixed or split mold structures. When the bending radius needs to be adjusted to fit different specifications of clamps, the machine must be stopped to disassemble bolts and replace the entire mold set, with each mold change taking 1-2 hours. For example, when producing clamps with bending radii of Φ30mm and Φ50mm, the current equipment is too cumbersome, requiring the complete disassembly of the original mold components before use. This process is cumbersome, and bending accuracy fluctuates due to mold positioning errors, resulting in a scrap rate of over 8%. This "one specification, one mold" production mode severely restricts the flexibility of multi-variety, small-batch production and cannot meet the diverse clamp requirements in power construction.

[0004] In the workpiece unloading process, traditional equipment often relies on manual labor to pry the forming clamps from the mold. Because the bent workpiece fits tightly with the mold, it often requires the use of a rubber hammer or clamps, which is not only time-consuming and labor-intensive but also prone to causing scratches or deformation on the workpiece surface. Especially for high-strength steel clamps, manual unloading is inefficient and poses safety hazards. In addition, although some equipment is equipped with a simple unloading plate, it lacks an adaptive adjustment mechanism, making it difficult to adapt to the demolding requirements of workpieces with different bending radii, resulting in frequent jams in the unloading process and affecting production continuity.

[0005] As power grid construction moves towards intelligence and modularization, the demand for customized guy wire clamps is increasing. The shortcomings of traditional bending machines in terms of mold changing efficiency and material cutting convenience are becoming more and more prominent. There is an urgent need to develop new equipment with rapid bending radius adjustment and automated material cutting functions to improve production flexibility and processing efficiency. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a wire clamp bending machine with an adjustable bending radius, which solves the technical problem that the existing equipment is too cumbersome, requiring complete disassembly of the original mold components before it can be used, resulting in a cumbersome operation process.

[0007] According to one aspect, at least one embodiment of this disclosure provides a wire clamp bending machine with an adjustable bending radius, comprising:

[0008] The equipment rack and the feeding rack are arranged on the top of the equipment rack;

[0009] A drive motor and a bending assembly are provided, wherein the drive motor is disposed at the bottom of the equipment frame and the bending assembly is disposed on the equipment frame;

[0010] A feeding assembly is disposed on the feeding rack and the equipment rack;

[0011] The bending assembly includes a flip plate, which is rotatably connected to the equipment frame via a rotating shaft. A second motor is provided at the bottom of the equipment frame. A transmission wheel is provided at the output end of the second motor and at one end of the rotating shaft of the flip plate. The transmission wheels are connected by a belt drive. Forming columns are provided on both surfaces of the flip plate. A bending frame is provided on the equipment frame.

[0012] As a further technical solution, a pair of diameter-increasing rings are fitted on the forming column, and a rotating seat is rotatably connected inside the equipment frame. The rotating seat is connected to the output end of the drive motor, and a fixed shaft is provided on the surface of the rotating seat.

[0013] As a further technical solution, a pair of fixed seats are provided on the surface of the equipment frame, and a movable frame is slidably connected inside the fixed seats. The movable frame and the fixed shaft are rotatably connected by a transmission rod through a pin.

[0014] As a further technical solution, the bending frame is slidably inserted into the movable frame, a pair of telescopic cylinders are provided on the surface of the equipment frame, a support block is provided at the output end of the telescopic cylinder, a stabilizing rod is provided on the surface of the support block, and the stabilizing rod is movably connected to the equipment frame.

[0015] As a further technical solution, the feeding assembly includes a pair of second cylinders, both of which are fixed to the surface of the equipment frame. The feeding frame is fixed to the output end of the second cylinders, and a sliding layer is provided on the top of the feeding frame.

[0016] As a further technical solution, a third cylinder is provided at the top of the feeding rack, a pressure plate is provided at the output end of the third cylinder, a rectangular opening is provided at the bottom of the feeding rack, and a baffle is rotatably connected to the bottom of the feeding rack, the baffle being rotated by a motor.

[0017] As a further technical solution, the surface of the slip layer is an inclined structural surface, and the surface of the slip layer is a wavy raised structural surface.

[0018] As a further technical solution, the flip plate can rotate 360° around the rotation axis.

[0019] As a further technical solution, the end face of the support block is an arc-shaped structure surface, and the end face of the support block is in contact with the surface of the diameter-increasing ring.

[0020] The beneficial effects of the embodiments disclosed herein are as follows:

[0021] 1. In this disclosure, the bending assembly achieves bending radius adjustment through the diameter-increasing ring on the forming column. Different diameter-increasing rings can be replaced without disassembling the mold, eliminating the cumbersome operation of completely disassembling the mold assembly required by traditional equipment. This significantly shortens mold changeover time and improves the flexibility of producing multi-specification clamps. The flip plate can rotate 360° and automatically flips over for unloading after bending, avoiding workpiece damage caused by manual prying. The arc-shaped structure of the support block fits snugly against the diameter-increasing ring, ensuring uniform stress on the sheet metal during bending, improving bending accuracy, and automating clamp bending and unloading operations, thus reducing labor intensity.

[0022] 2. In this disclosure, the feeding assembly adjusts the position of the feeding rack via a second cylinder, which, in conjunction with the inclined wavy surface of the sliding layer, allows the sheet metal to slide smoothly. A third cylinder and a pressure plate position and fix the sheet metal. The baffle is controlled by a motor to rotate, enabling intermittent feeding and ensuring precise conveying of the sheet metal according to the bending rhythm. This eliminates the need for frequent manual loading, improving feeding efficiency. This assembly enables continuous automatic feeding of the sheet metal, reducing manual intervention and avoiding jamming during the feeding process. Working in conjunction with the bending assembly, it ensures continuous production of the bending machine, improves overall processing efficiency, and meets the diverse batch production needs of clamps in power construction.

[0035] like Figures 1-4 As shown, it illustrates an adjustable bending radius wire clamp bending machine according to an embodiment of the present disclosure, comprising:

[0036] The equipment frame 1 and the feeding rack 2 are provided on the top of the equipment frame 1;

[0037] The drive motor 3 and the bending assembly 4 are provided, wherein the drive motor 3 is disposed at the bottom of the equipment frame 1 and the bending assembly 4 is disposed on the equipment frame 1;

[0038] Feeding assembly 5, which is disposed on the feeding rack 2 and the equipment rack 1;

[0039] The bending assembly 4 includes a flip plate 4-1, which is rotatably connected to the equipment frame 1 via a rotating shaft. A second motor 4-2 is provided at the bottom of the equipment frame 1. A transmission wheel 4-3 is provided at both the output end of the second motor 4-2 and one end of the rotating shaft of the flip plate 4-1. The transmission wheels 4-3 are connected by a belt drive. Forming columns 4-4 are provided on both surfaces of the flip plate 4-1. A bending frame 4-5 is provided on the equipment frame 1. A pair of diameter-increasing rings 4-6 are fitted on the forming columns 4-4. A rotating seat 4-7 is rotatably connected inside the equipment frame 1 and is connected to the output end of the drive motor 3. Next, a fixed shaft 4-8 is provided on the surface of the rotating seat 4-7, and a pair of fixed seats 4-9 are provided on the surface of the equipment frame 1. A movable frame 4-10 is slidably connected inside the fixed seat 4-9. A transmission rod 4-11 is rotatably connected between the movable frame 4-10 and the fixed shaft 4-8 through a pin. The bending frame 4-5 is slidably inserted into the movable frame 4-10. A pair of telescopic cylinders 4-12 are provided on the surface of the equipment frame 1. A support block 4-13 is provided at the output end of the telescopic cylinder 4-12. A stabilizing rod 4-14 is provided on the surface of the support block 4-13. The stabilizing rod 4-14 is slidably connected to the equipment frame 1.

[0040] In some examples, a bending assembly 4 is designed to realize the bending radius adjustment and flipping unloading functions of the wire clamp. The assembly is centered on a flipping plate 4-1 that is rotatably connected to the equipment frame 1 via a rotating shaft. The second motor 4-2 at the bottom drives the flipping plate 4-1 to rotate via belt drive. After the clamp is bent, the flipping plate 4-1 can be flipped 180° to unload the workpiece. The forming columns 4-4 on both surfaces of the flipping plate 4-1 are used for clamp bending and forming. The diameter-increasing rings 4-6 fitted on the columns can adjust the bending radius by replacing the rings with different outer diameters to adapt to the production needs of clamps of different specifications.

[0041] The rotating seat 4-7 inside the equipment frame 1 is driven to rotate by the drive motor 3. Its surface fixed shaft 4-8 is connected to the movable frame 4-10 through the transmission rod 4-11. When the rotating seat 4-7 rotates, the transmission rod 4-11 pushes the movable frame 4-10 to slide in the fixed seat 4-9, which drives the bending frame 4-5 to move along the axis of the movable frame 4-10, applying bending force to the plate placed on the forming column 4-4. The telescopic cylinder 4-12 on the surface of the equipment frame 1 drives the two support blocks 4-13 to move left and right, which can fit against the diameter increasing ring 4-6 or the surface of the forming column 4-4 to form two symmetrical sides of the clamp.

[0042] Through the radius adjustment of the diameter-increasing ring 4-6, the material-feeding rotation of the flipping plate 4-1, and the reciprocating motion of the bending frame 4-5, the bending assembly 4 achieves precise bending and convenient material feeding of clamps with different radii.

[0043] like Figures 1-4 As shown in the figure, the feeding assembly 5 in this embodiment includes a pair of second cylinders 5-1, both of which are fixed to the surface of the equipment frame 1. The feeding frame 2 is fixed to the output end of the second cylinders 5-1. A sliding layer 5-2 is provided on the top of the feeding frame 2. A third cylinder 5-3 is provided on the top of the feeding frame 2. A pressure plate 5-4 is provided at the output end of the third cylinder 5-3. A rectangular opening 5-5 is provided at the bottom of the feeding frame 2. A baffle 5-6 is rotatably connected to the bottom of the feeding frame 2. The baffle 5-6 is rotated by a motor.

[0044] In some examples, a feeding assembly 5 is designed to achieve continuous feeding of the sheet material. This assembly uses a second cylinder 5-1 fixed to the surface of the equipment frame 1 as a lateral drive mechanism. The feeding rack 2 connected to its output end can move back and forth, and can leave the position when the flip plate 4-1 is unloading and adjust the unloading position. The sliding layer 5-2 at the top of the feeding rack 2 is made of a low friction coefficient material, which facilitates the smooth sliding of the sheet material. The pressure plate 5-4 at the output end of the third cylinder 5-3 at the top can press down and fix the sheet material. When the sheet material is continuously put in, it can press down the second to last one.

[0045] The rotating baffle 5-6 is controlled by a motor to rotate. The baffle 5-6 blocks the sheet material that is about to be fed. When feeding is required, the motor drives the baffle 5-6 to rotate. The sheet material falls to the bending station under the action of gravity. After feeding is completed, the output end of the third cylinder 5-3 retracts, and the sheet material slides down and hits the baffle 5-6. Then the third cylinder 5-3 is started again to press the next sheet material, realizing intermittent continuous feeding.

[0046] Through the height adjustment of the second cylinder 5-1, the positioning and fixing of the pressure plate 5-4, and the rotation control of the baffle 5-6, the feeding component 5 can accurately convey the sheet metal according to the bending rhythm, ensuring the continuous operation efficiency of the bending machine.

[0047] For example, such as Figure 1 As shown, the surface of the slip layer 5-2 is an inclined structure surface, and the surface of the slip layer 5-2 is a wavy raised structure surface.

[0048] In some examples, the wavy, raised structure, combined with the inclined surface, can reduce friction on the sheet material, making the sliding smoother.

[0049] For example, such as Figure 3 As shown, the flip plate 4-1 rotates 360° around the rotation axis.

[0050] In some examples, by rotating 360°, the flip plate 4-1 can be continuously rotated in one direction, so that the formed clamp falls to the same position each time.

[0051] For example, such as Figure 1 As shown, the end face of the support block 4-13 is an arc-shaped structure surface, and the end face of the support block 4-13 is in contact with the surface of the diameter-increasing ring 4-6.

[0052] In some examples, the curved structural surface helps to maintain the fit between the support block 4-13, the diameter-increasing ring 4-6, and the forming column 4-4, making the structure more stable.

[0053] In actual use: the equipment frame 1 is fixed to the work site. The feeding frame 2 is adjusted in position by the second cylinder 5-1. The sliding layer 5-2 is inclined on the top of the feeding frame 2 and has a wavy convex shape. The plate is placed on the sliding layer 5-2. The plate slides down and presses against the retaining frame 5-6. The third cylinder 5-3 drives the pressure plate 5-4 to press down and fix the next plate. The retaining frame 5-6 is rotated by the motor to put down another plate. The drive motor 3 drives the rotating seat 4-7 to rotate. The fixed shaft 4-8 is connected to the transmission rod. 4-11 pushes the movable frame 4-10 to slide within the fixed seat 4-9, causing the bending frame 4-5 to move repeatedly, pressing the sheet metal against the surface of the diameter-increasing ring 4-6 or the forming column 4-4. After forming, the output end of the telescopic cylinder 4-12 controls the support block 4-13 to retract. The second motor 4-2 drives the flipping plate 4-1 to rotate through belt drive, and the sheet metal falls downwards naturally. Then, the next sheet metal continues to fall. The bending radius can be adjusted by replacing the diameter-increasing ring 4-6 on the forming column 4-4 and the bending frame 4-5.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
