Description

Technical Field

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

[0002] A triangular-shaped special-shaped cable is a special-shaped cable with a triangular cross-section. The three sides of this shape are generally composed of yttrium-based high-temperature superconducting tapes or other conductive materials and are used to transmit three-phase currents;

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

[0004] In the prior art field, during the bending process of triangular-shaped special-shaped cables, due to the relatively large mass of the triangular-shaped special-shaped cables themselves, before the bending operation is carried out, it is necessary to manually lift both sides of the cable to accurately place it at the designated working position of the bending device. During this process, manual direct intervention is required for each bending operation, which not only significantly increases the input of labor costs but also has an adverse impact on the bending processing efficiency of triangular-shaped special-shaped cables. Especially when multiple bends need to be made on triangular-shaped special-shaped cables, the operator has to repeatedly move the position of the cable and perform multiple disassembly and assembly operations, further exacerbating the low bending processing efficiency. Summary of the Invention

[0005] The purpose of the present invention is to solve the disadvantages existing in the background art and to propose a cable bending device and a using method thereof.

[0013] Preferably, the conveying mechanism further includes a side frame fixedly connected to one side of the top end of the connecting frame. An electric cylinder is fixedly connected to the bottom end of the side frame. The telescopic end of the electric cylinder is fixedly connected with a fixed frame. At both sides of the electric cylinder corresponding to the top end of the fixed frame, guiding columns are fixedly connected. Both of the guiding columns penetrate through the side frame slidably.

[0014] Preferably, on one side of the inner wall of the fixed frame, a driving shaft is rotatably connected. A driving wheel is fixedly connected to the outer wall of the driving shaft.

[0017] A method for using a cable bending device includes the following steps:

[0018] Step 1: First, start the third-level cylinder to push the U-shaped frame downward, and make the V-shaped plate contact the inclined surfaces on both sides of the triangular special-shaped cable. At this time, start the exhaust fan and generate negative pressure in the fixed suction cup through the connecting pipe, so as to adsorb and fix the triangular special-shaped cable. Then lift the triangular special-shaped cable. At this time, perform a bending operation through the cooperation of the bending wheel and the third-level cylinder;

[0019] Step 2: After the bending operation, the triangular special-shaped cables on both sides of the connecting frame can be adjusted to a horizontal state through the adjustment mechanism;

[0022] 1. Through the setting of the grasping mechanism, the inner wall of the V-shaped plate can contact the inclined surface of the triangular special-shaped cable by moving the third-level cylinder downward. Then, negative pressure is generated in the fixed suction cup by the exhaust fan to fix the triangular special-shaped cable. At this time, reverse-start the third-level cylinder to place the triangular special-shaped cable on the working station. Manual participation is required in this process, thus reducing the input of labor costs and improving the bending efficiency. Then, the triangular special-shaped cable is bent through the bending mechanism;

[0023] 2. Through the setting of the adjustment mechanism, the adjustment plate can extend below the triangular special-shaped cable. Then, the adjustment plate is lifted, and under the limitation of the fixed frame, the triangular special-shaped cables on both sides can be in a horizontal state, which is convenient for subsequent conveying operations;

[0024] 3. Through the provided conveying mechanism, the electric push rod can drive the conveying wheels to move towards each other, making the conveying wheels on both sides contact each other and contact the bottom of the triangular-shaped cable. Then, the electric cylinder moves downward to make the groove on the driving wheel catch on the triangular top of the triangular-shaped cable, so as to convey the triangular-shaped cable. Furthermore, multiple parts of the triangular-shaped cable can be bent, and the overall bending efficiency can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

V-shaped plates 25 are fixedly connected to the outer walls of the two rotating shafts 36. The inner walls of the two V-shaped plates 25 contact the two inclined surfaces of the triangular special-shaped cable 3. Four groups of fixed suction cups 35 are fixedly penetrated through the two ends of the two V-shaped plates 25. The four groups of fixed suction cups 35 adsorb on the two inclined surfaces of the triangular special-shaped cable 3.

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

[0041] AsFigure 1 , Figure 2 , Figure 6 As shown in Figure 1 , Figure 2 , and Figure 6 , the bending mechanism further includes a hydraulic rod 10 fixedly penetrating 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, and the first driven plate 27 is rotatably connected to a bending wheel 28. It also includes square holes 17 formed on both sides of the top end of the connecting frame 1. The inner walls of the two square holes 17 are both slidably connected to sliders 19. Springs 18 are fixedly connected between the two groups of sliders 19 and the square holes 17 respectively. The two springs 18 and the two three-stage cylinders 2 penetrate through respectively. A guiding telescopic mechanism 16 penetrates through each of the two sliders 19, and the two guiding telescopic mechanisms 16 are fixedly connected to two U-shaped frames 32 respectively. The elastic action of the spring 18 can make the slider 19 automatically reset, and the guiding telescopic mechanism 16 can limit the position of the U-shaped frame 32.

[0042] As Figure 1 , Figure 3 , Figure 4 As shown in Figure 1 , Figure 3 , and Figure 4 , the conveying mechanism includes L-shaped plates 8 fixedly connected to both sides of one end of the connecting frame 1 and vertical plates 23 fixedly connected to both side ends of the connecting frame 1. Electric push rods 6 penetrate through the two vertical plates 23 and the two L-shaped plates 8 respectively. The telescopic end of each electric push rod 6 is fixedly connected to a second driven plate 29. A conveying wheel 12 is rotatably connected to one end of each second driven plate 29 close to each other. A guiding rod 7 is fixedly connected to the other end of each second driven plate 29. Each guiding rod 7 penetrates through the L-shaped plate 8 and the vertical plate 23 respectively. Bottom plates 9 are fixedly connected to both sides of the bottom end of the connecting frame 1. Brake universal wheels are symmetrically and fixedly connected to the bottom ends of the two bottom plates 9. The position of the second driven plate 29 can be limited by the circular block on the guiding rod 7, so that the groove between the conveying wheels 12 is directly below the triangular-shaped cable 3.

[0043] As Figure 1 , Figure 3 , Figure 9 As shown in Figure 1 , Figure 3 , and Figure 9 , the conveying mechanism further includes a side frame 15 fixedly connected to one side of the top end of the connecting frame 1. An electric cylinder 21 is fixedly connected to the bottom end of the side frame 15. The telescopic end of the electric cylinder 21 is fixedly connected to a fixed frame 13. Guide columns 20 are fixedly connected to both sides of the fixed frame 13 corresponding to the electric cylinder 21. The two guide columns 20 both slide through the side frame 15. A driving shaft 37 is rotatably connected to one side of the inner wall of the fixed frame 13. A driving wheel 14 is fixedly connected to the outer wall of the driving shaft 37. The driving wheel 14 is provided with a groove adapted to the shape of the top of the triangular-shaped cable 3. A second motor 26 is fixedly connected to one end of the fixed frame 13. The driving end of the second motor 26 is fixedly connected to the driving shaft 37. The guide columns 20 can limit the position of the fixed frame 13 to prevent the fixed frame 13 from moving too far.

[0044] As Figure 5 , Figure 10As shown in the figure, the adjustment mechanism includes a fixed frame 4 fixedly connected to the L-shaped plate 8. Adjusting blocks 11 are provided on the inner walls of both fixed frames 4. A adjusting plate 5 slidably penetrates through both adjusting blocks 11. Electric telescopic rods 30 are fixedly connected to the lower sides of the two adjusting blocks 11 corresponding to the adjusting plate 5. Fixed blocks 31 are fixedly connected to the telescopic ends of the two electric telescopic rods 30. The two fixed blocks 31 and the two adjusting plates 5 are fixedly connected respectively. By moving the moving block 40 to drive the adjusting block 11 to move, the movement of the adjusting plate 5 is completed. Limiting blocks are fixedly connected to both sides of the adjusting plate 5 to limit the position of the adjusting plate 5.

[0045] As Figure 11 shown in the figure, sliding grooves 39 are opened on the sides close to each other on the inner walls of the two fixed frames 4. Moving blocks 40 are slidably connected to the inner walls of the two sliding grooves 39. The two moving blocks 40 and the two adjusting blocks 11 are fixedly connected respectively. First motors 22 are fixedly connected to the tops of the two fixed frames 4. Driving ends of the two first motors 22 are fixedly connected with threaded rods 38. The two threaded rods 38 are rotatably connected to the two sliding grooves 39 respectively. The two threaded rods 38 and the two moving blocks 40 are threadedly connected respectively. By performing a limiting operation on the moving block 40 through the sliding groove 39, the bottom of the triangular-shaped cable 3 on the adjusting plate 5 can exceed the height of the conveying wheel 12, facilitating subsequent conveying operations.

[0046] A method for using a cable bending device includes 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-shaped cable 3. At this time, start the exhaust fan 34 and generate negative pressure in the fixed suction cup 35 through the connecting pipe 33, so as to adsorb and fix the triangular-shaped cable 3. Then lift the triangular-shaped cable 3. At this time, perform a bending operation through 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, clamp one side of the triangular-shaped cable 3 through the conveying mechanism and convey the triangular-shaped cable 3, so as to perform bending operations on multiple parts of the triangular-shaped cable 3 and improve the bending efficiency.

[0050] Working principle: First, place the bending device in a suitable position, then fix it through the braking system on the brake universal wheels. Then, control the three-stage cylinder 2 to push the U-shaped frame 32 downward through the synchronous controller, and drive 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 as to adsorb and fix the triangular special-shaped cable 3. Then, reverse-start the three-stage cylinder 2 to drive the triangular special-shaped cable 3 upward. At this time, start the hydraulic rod 10 to push the first driven plate 27 and the bending wheel 28 to move, and 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, start the three-stage cylinder 2 again to drive the U-shaped frame 32 downward, and make the bottom of the triangular special-shaped cable 3 contact the groove on the bending wheel 28. Then, continue to move the triangular special-shaped cable 3 downward to bend it. At the same time, the slider 19 compresses the spring 18. At the same time, due to the existence of the rotating shaft 36, the V-shaped plate 25 can deflect, and the bending operation is completed. Therefore, manual participation is not possible during the bending process, and the bending efficiency is improved;

[0051] After the bending is completed, start the electric telescopic rod 30 to push the fixed block 31 and the adjusting plate 5 in the direction close to the triangular special-shaped cable 3 until the adjusting plate 5 reaches below the triangular special-shaped cable 3. Then, start the first motor 22 to drive the threaded rod 38 to rotate. Through the threading effect of the threaded rod 38, the moving block 40 can move upward. Due to the existence of the chute 39, the moving block 40 can be limited. At this time, the heights on both sides of the triangular special-shaped cable 3 exceed the conveying wheels 12. Then, start the electric push rod 6 to push the second driven plate 29 in the direction of approaching each other, and make the conveying wheels 12 on both sides contact. Then, reverse-start the first motor 22 and drive the threaded rod 38 to rotate in the reverse direction. At this time, the moving block 40 and the adjusting plate 5 move downward to release the contact with the triangular special-shaped cable 3, and the bottom of the triangular special-shaped cable 3 falls into the groove between the conveying wheels 12. Then, start the electric cylinder 21 to drive the fixed frame 13 and the driving wheel 14 downward, and make the groove on the driving wheel 14 contact the top of the triangular special-shaped cable 3 to complete the clamping of the triangular special-shaped cable 3. Then, turn off the exhaust fan 34 to release the adsorption and fixation of the triangular special-shaped cable 3. At this time, start to drive the V-shaped plate 25 upward to avoid affecting the conveying of the triangular special-shaped cable 3. At this time, start the second motor 26 to drive the driving shaft 37 and the driving wheel 14 to rotate, and convey the triangular special-shaped cable 3. Through the above operations, multiple places of the triangular special-shaped cable 3 can be bent, and the overall bending efficiency is improved.

[0052] The foregoing has shown and described 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 by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present invention.
