Description

Technical Field

[0001] The present invention relates to the technical field of wire bending, and in particular to a cable bending device and a method of using the same. Background Art

[0002] Triangular shaped cables are shaped cables with a triangular cross section. The three sides of this shape are generally composed of yttrium-based high-temperature superconducting tape or other conductive materials, and are used to transmit three-phase current.

[0003] The main purpose of cable bending is to ensure that the cable can be laid according to the predetermined path and angle during installation to meet the needs of the electrical system. Therefore, a bending device is required during the bending process.

[0004] In the prior art, during the bending processing of triangular special-shaped cables, due to the large mass of the triangular special-shaped cables themselves, it is necessary to manually lift both sides of the cables before performing the bending operation so as to accurately place them on the designated workstations of the bending device. During this process, each bending operation requires direct manual intervention, which not only significantly increases the labor cost investment, but also has an adverse effect on the bending processing efficiency of the triangular special-shaped cables. In particular, when multiple bending processes need to be performed on the triangular special-shaped cables, the operator has to repeatedly move the cable position and perform multiple disassembly and assembly operations, which further aggravates the low efficiency of the bending processing.

[0040] like Figure 3 、 Figure 8 As shown, the bending mechanism includes a bending wheel 28, which contacts the bottom of the triangular shaped cable 3 and performs the bending process in cooperation with the three-stage cylinder 2. The end of the first driven plate 27 away from the bending wheel 28 corresponds to the hydraulic rod 10 and is fixedly connected to the limit rod 24 on both sides. Both limit rods 24 slide through the connecting frame 1. The two three-stage cylinders 2 are controlled by a synchronous controller to operate synchronously.

[0041] like Figure 1 、 Figure 2 、 Figure 6 As shown, the bending mechanism also includes a hydraulic rod 10 fixedly extending through the side end of the connecting frame 1. The telescopic end of the hydraulic rod 10 is fixedly connected to a first driven plate 27. The first driven plate 27 is rotatably connected to the bending wheel 28.

[0042] like Figure 1 、 Figure 3 、 Figure 4 As shown, the conveying mechanism includes an L-shaped plate 8 fixedly connected to both sides of one end of the connecting frame 1 and a vertical plate 23 fixedly connected to both ends of the connecting frame 1. The two vertical plates 23 and the two L-shaped plates 8 are fixedly penetrated by an electric push rod 6. The telescopic end of each electric push rod 6 is fixedly connected to a second driven plate 29. Each second driven plate 29 is rotatably connected to the conveying wheel 12 at one end close to each other. The other end of each second driven plate 29 is fixedly connected to a guide rod 7. Each guide rod 7 passes through the L-shaped plate 8 and the vertical plate 23. The bottom end of the connecting frame 1 is fixedly connected to a bottom plate 9 on both sides. The bottom ends of the two bottom plates 9 are symmetrically fixedly connected to brake universal wheels. The circular block on the guide rod 7 can limit the position of the second driven plate 29 so that the groove between the conveying wheels 12 is directly below the triangular special-shaped cable 3.

[0043] like Figure 1 、 Figure 3 、 Figure 9 As shown, the conveying mechanism also includes a side frame 15 fixedly connected to one side of the top of the connecting frame 1. The bottom end of the side frame 15 is fixedly connected to an electric cylinder 21. The telescopic end of the electric cylinder 21 is fixedly connected to the fixed frame 13. The top of the fixed frame 13 is fixedly connected to both sides of the electric cylinder 21. The two guide columns 20 slide through the side frame 15. The inner wall of the fixed frame 13 is rotatably connected to a drive shaft 37. The outer wall of the drive shaft 37 is fixedly connected to a drive wheel 14. The drive wheel 14 has a groove that matches the shape of the top of the triangular special-shaped cable 3. One end of the fixed frame 13 is fixedly connected to a second motor 26. The driving end of the second motor 26 is fixedly connected to the drive shaft 37. The guide column 20 can limit the fixed frame 13 to prevent the fixed frame 13 from moving too far.

[0044] like Figure 5 、 Figure 10As shown, the adjustment mechanism includes a fixed frame 4 fixedly connected to the L-shaped plate 8. The inner walls of the two fixed frames 4 are each provided with an adjustment block 11. The adjustment plate 5 slides through each adjustment block 11. The two adjustment blocks 11 are fixedly connected to the lower portion of the corresponding adjustment plate 5. The telescopic ends of the two electric telescopic rods 30 are fixedly connected to the fixed blocks 31. The two fixed blocks 31 are respectively fixedly connected to the two adjustment plates 5. The adjustment plates 5 are moved by the movement of the adjustment blocks 11 with the moving blocks 40. The adjustment plates 5 are fixedly connected to the limit blocks on both sides of the adjustment plates 5 to limit their position.

[0045] like Figure 11 As shown, the inner walls of the two fixed frames 4 are each provided with a chute 39 on one side thereof, and the inner walls of the two chute 39 are slidably connected to a moving block 40. The two moving blocks 40 are fixedly connected to the two adjustment blocks 11. The tops of the two fixed frames 4 are fixedly connected to the first motor 22. The driving ends of the two first motors 22 are fixedly connected to the threaded rods 38. The two threaded rods 38 are rotatably connected to the two chute 39, and the two threaded rods 38 are threadedly connected to the two moving blocks 40. The chute 39 limits the moving blocks 40, so that the bottom of the triangular special-shaped cable 3 on the adjustment plate 5 can exceed the height of the conveying wheel 12, facilitating subsequent conveying operations.

[0046] A method for using a cable bending device comprises the following steps:

[0047] Step 1: First, start the three-stage cylinder 2 to push the U-shaped frame 32 downward, and make the V-shaped plate 25 contact the inclined surfaces on both sides of the triangular special-shaped cable 3. Then start the exhaust fan 34 and generate negative pressure in the fixing suction cup 35 through the connecting pipe 33, so that the triangular special-shaped cable 3 can be adsorbed and fixed. Then, the triangular special-shaped cable 3 is lifted up, and the bending operation is performed under the cooperation of the bending wheel 28 and the three-stage cylinder 2.

[0048] Step 2: After the bending operation, the triangular shaped cables 3 on both sides of the connecting frame 1 can be adjusted to a horizontal state through the adjustment mechanism;

[0049] Step 3: At this time, one side of the triangular shaped cable 3 is clamped by the conveying mechanism, and the triangular shaped cable 3 is conveyed, so that the triangular shaped cable 3 can be bent at multiple locations to improve the bending efficiency.

[0050] Working principle: First, place the bending device in a suitable position, then fix it by the brake system on the universal wheel, then control the three-stage cylinder 2 through the synchronous controller to push the U-shaped frame 32 downward, and move the rotating shaft 36 and the V-shaped plate 25 downward, and make the inner wall of the V-shaped plate 25 contact the two inclined surfaces of the triangular special-shaped cable 3, then start the exhaust fan 34 and generate a negative pressure effect in the fixed suction cup 35 through the connecting pipe 33, so that the triangular special-shaped cable 3 can be adsorbed and fixed, then reverse the three-stage cylinder 2 to move the triangular special-shaped cable 3 upward, then start the hydraulic rod 10 to push the first A driven plate 27 and a bending wheel 28 move. At this time, the limiting rod 24 can limit the first driven plate 27 so that the groove on the bending wheel 28 is aligned with the bottom of the triangular special-shaped cable 3. At this time, the three-stage cylinder 2 is started again to move the U-shaped frame 32 downward, and the bottom of the triangular special-shaped cable 3 contacts the groove on the bending wheel 28. Then, the triangular special-shaped cable 3 continues to move downward to bend. At the same time, the slider 19 compresses the spring 18. At the same time, the existence of the rotating shaft 36 can deflect the V-shaped plate 25 and complete the bending operation. Therefore, no manual intervention is required during the bending process, thereby improving the bending efficiency.

[0051] When the bending is completed, the electric telescopic rod 30 is started to push the fixed block 31 and the adjustment plate 5 toward the direction close to the triangular shaped cable 3 until the adjustment plate 5 reaches the bottom of the triangular shaped cable 3. Then the first motor 22 is started to rotate with the threaded rod 38. The threaded effect of the threaded rod 38 can make the moving block 40 move upward. Due to the existence of the slide groove 39, the moving block 40 can be limited. At this time, the height of both sides of the triangular shaped cable 3 exceeds the conveying wheel 12. At this time, the electric push rod 6 is started to push the second driven plate 29 toward each other and make the conveying wheels 12 on both sides contact. At this time, the first motor 22 is started in the reverse direction and rotates in the reverse direction with the threaded rod 38. At this time, the moving block 40 and the adjustment plate 5 move downward, releasing the tension. The triangular shaped cable 3 contacts the V-shaped plate 25, and the bottom of the triangular shaped cable 3 falls into the groove between the conveying wheels 12. At this time, the electric cylinder 21 is started to move the fixing frame 13 and the driving wheel 14 downward, and the groove on the driving wheel 14 is in contact with the top of the triangular shaped cable 3 to complete the clamping of the triangular shaped cable 3. Then, the exhaust fan 34 is turned off to release the adsorption and fixation of the triangular shaped cable 3. At this time, the triangular shaped cable 3 is started to move upward with the V-shaped plate 25 to avoid affecting the conveying of the triangular shaped cable 3. At this time, the second motor 26 is started to rotate the driving shaft 37 and the driving wheel 14, and the triangular shaped cable 3 is conveyed. Through the above operations, the triangular shaped cable 3 can be bent at multiple locations to improve the overall bending efficiency.

[0052] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
