Description

Technical Field

[0001] This utility model relates to the field of wire rope production stranding technology, specifically a wire rope production stranding machine. Background Technology

[0002] Modern steel wire rope is a helical bundle of steel wires that meet the requirements of mechanical properties and geometric dimensions, twisted together according to certain rules. Steel wire rope has high strength, light weight, and stable operation. A stranding machine is required in the production process of steel wire rope.

[0003] Chinese patent CN211446379U discloses a wire rope twisting device, including a twisting machine, several twisting rings with identical structures, and a coiling structure. The twisting rings are mounted on the twisting machine and have several identical lubrication structures on them. The coiling structure is mounted on the twisting machine. This utility model relates to the field of wire rope twisting technology. This wire rope twisting device lubricates the wire rope before twisting through its lubrication structures, and then directly twists the rope. This reduces the friction between the wire and components, thereby reducing equipment and wire wear, improving wire quality, and protecting the equipment. Simultaneously, the coiling structure improves assembly and disassembly efficiency during equipment coiling, saving downtime and accelerating production speed.

[0004] In existing wire rope twisting machines, the wires are prone to loosening during the twisting process, and the tension of the wires cannot be adjusted, resulting in poor adjustability of the device. Therefore, a wire rope production wire rope twisting machine is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a wire rope production twisting machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A wire rope twisting machine of this utility model includes a base, a support plate mounted on the base, a rotating plate rotatably mounted on the support plate, three sets of first fixed rods rotatably mounted on the rotating plate, a first fixed plate being engaged with the first fixed rod, a first winding wheel sleeved on the first fixed rod, and steel wire wound on the first winding wheel. A rotating disk is welded onto the rotating plate, and three sets of wire holes are opened on the rotating disk, with steel wires passing through the wire holes. Plate grooves are symmetrically opened on both sides of the wire holes in the rotating disk, and rod grooves are opened in the rotating disk. A lead screw is rotatably mounted on the inner wall of the rod groove via bearings. The thread directions on the lead screw are symmetrical and opposite, and a knob is welded to the top side of the lead screw. Two sets of movable plates are symmetrically fitted on the lead screw. The movable plates are assembled in the plate groove, and connecting blocks are welded to the movable plates. Clamping plates are welded to the connecting blocks. The two sets of clamping plates are located in the wire hole. By rotating the knob, the lead screw is driven to rotate, and the lead screw drives the two sets of movable plates to move synchronously relative to each other. The two sets of movable plates drive the two sets of connecting blocks to move synchronously relative to each other, and the two sets of connecting blocks drive the two sets of clamping plates to move synchronously relative to each other. This achieves the reduction of the distance between the two sets of clamping plates, so that the two sets of clamping plates contact the surface of the steel wire. When the steel wire is twisted, frictional resistance will be generated between the steel wire and the clamping plates. The smaller the distance between the two sets of clamping plates, the greater the frictional resistance will be, thereby increasing the tension of the steel wire from the wire hole to the wire frame. This structure can adjust the tension of the steel wire, which is beneficial to improving the adjustability of the device.

[0007] Preferably, a drive rod is welded to the rotating disk, and the other side of the drive rod is rotatably connected to the support plate. A first motor is mounted on the support plate through a protective cover, and the output shaft of the first motor is fixedly connected to the drive rod. A wire frame is fixedly mounted on the base through a bracket, and a support frame is welded to the base. A second fixed rod is rotatably mounted on the support frame, and a second fixed plate is snapped onto the second fixed rod. A second motor is mounted on the base through a machine base, and the output shaft of the second motor is connected to the second fixed rod. A second winding wheel is sleeved on the second fixed rod, and a steel wire rope is wound on the second winding wheel. The steel wire rope is wound by the second winding wheel, realizing the traction of three steel wires by the second winding wheel. At the same time, the drive rod drives the rotating disk to rotate, the rotating disk drives the rotating plate to rotate, the rotating plate drives the three sets of first fixed rods on it to rotate, and the first fixed rods drive the first winding wheel on them to rotate. That is, the rotating disk and the three sets of first winding wheels rotate synchronously in a circular motion. The rotating disk drives the three steel wires to rotate, realizing the twisting of the steel wires, which is beneficial to improving the twisting efficiency.

[0008] The advantages of this utility model are:

[0009] 1. This utility model, by rotating a knob, drives the lead screw to rotate, which in turn drives two sets of moving plates on it to move synchronously relative to each other. The two sets of moving plates drive two sets of connecting blocks to move synchronously relative to each other, and the two sets of connecting blocks drive two sets of clamping plates to move synchronously relative to each other. This achieves the reduction of the distance between the two sets of clamping plates, so that the two sets of clamping plates come into contact with the surface of the steel wire. When the steel wire is twisted, frictional resistance is generated between the steel wire and the clamping plates. The smaller the distance between the two sets of clamping plates, the greater the frictional resistance will be, thereby increasing the tension of the steel wire from the wire hole to the conductor frame. This structure can adjust the tension of the steel wire, which is beneficial to improving the adjustability of the device.

[0010] 2. This utility model uses a second winding wheel to wind up the wire rope, thereby enabling the second winding wheel to pull three wires. At the same time, the drive rod drives the rotating disk to rotate, the rotating disk drives the rotating plate to rotate, the rotating plate drives the three sets of first fixed rods on it to rotate, and the first fixed rods drive the first winding wheel on them to rotate. That is, the rotating disk and the three sets of first winding wheels rotate synchronously, and the rotating disk drives the three wires to rotate, thereby realizing the twisting of the wires and improving the twisting efficiency.

[0018] Please see Figure 1-4 As shown, a wire rope twisting machine includes a base 1, a support plate 2 mounted on the base 1, a rotating plate 3 rotatably mounted on the support plate 2, three sets of first fixing rods 4 rotatably mounted on the rotating plate 3, first fixing plates 5 clamped onto the first fixing rods 4, a first winding wheel 6 sleeved on the first fixing rods 4, and steel wire 7 wound on the first winding wheel 6. A rotating disk 8 is welded onto the rotating plate 3, and three sets of wire holes 9 are opened on the rotating disk 8, with steel wire 7 passing through the wire holes 9. Plate grooves 10 are symmetrically opened on both sides of the wire holes 9 in the rotating disk 8. Rod grooves 11 are opened in the rotating disk 8. A lead screw 12 is rotatably mounted on the inner wall of the screw 11 via bearings. The threads on the lead screw 12 are symmetrically opposite in direction. A knob 13 is welded to the top side of the lead screw 12. Two sets of movable plates 14 are symmetrically fitted on the lead screw 12 and are assembled in the plate groove 10. A connecting block 15 is welded to the movable plate 14, and a clamping plate 16 is welded to the connecting block 15. The two sets of clamping plates 16 are located in the thread hole 9. A drive rod 17 is welded to the rotating disk 8. The other side of the drive rod 17 is rotatably connected to the support plate 2. A first motor 18 is mounted on the support plate 2 through a protective cover. The output shaft of the first motor 18 is connected to the drive rod. 17. Fixed connection: A wire frame 19 is fixedly installed on the base 1 via a bracket. A support frame 20 is welded to the base 1. A second fixed rod 21 is rotatably installed on the support frame 20. A second fixed plate 22 is snapped onto the second fixed rod 21. A second motor 25 is installed on the base 1 via a machine base. The output shaft of the second motor 25 is connected to the second fixed rod 21. A second take-up wheel 23 is sleeved on the second fixed rod 21. A steel wire rope 24 is wound on the second take-up wheel 23. During operation, in the existing twisting machine, the steel wire 7 is prone to loosening during the twisting process. Due to the inability to Adjusting the tension of the steel wire 7 results in poor adjustability of the device, affecting the neatness of the steel wire rope 24. By operating the second motor 25 and the first motor 18 simultaneously, the second motor 25 drives the second fixed rod 21 to rotate, which in turn drives the second winding wheel 23 on it to rotate circumferentially. The second winding wheel 23 winds up the steel wire rope 24, thus enabling the second winding wheel 23 to pull the three steel wires 7. The three steel wires 7 are released from the three sets of first winding wheels 6. The first winding wheels 6 drive the first fixed rod 4 to rotate, thus achieving rapid release of the steel wires 7.

[0019] Simultaneously, the operation of the first motor 18 drives the drive rod 17 to rotate, the drive rod 17 drives the rotating disk 8 to rotate, the rotating disk 8 drives the rotating plate 3 to rotate, the rotating plate 3 drives the three sets of first fixed rods 4 on it to rotate, the first fixed rods 4 drive the first winding wheel 6 on it to rotate, that is, the rotating disk 8 and the three sets of first winding wheels 6 rotate synchronously in a circular motion, and the rotating disk 8 drives the three steel wires 7 to rotate, thus realizing the twisting of the steel wires 7.

[0020] By rotating knob 13, the lead screw 12 is rotated, which in turn drives the two sets of moving plates 14 on it to move synchronously relative to each other. The two sets of moving plates 14 drive the two sets of connecting blocks 15 to move synchronously relative to each other, and the two sets of connecting blocks 15 drive the two sets of clamping plates 16 to move synchronously relative to each other. This reduces the distance between the two sets of clamping plates 16, allowing them to contact the surface of the steel wire 7. When the steel wire 7 is twisted, frictional resistance is generated between the steel wire 7 and the clamping plates 16. The smaller the distance between the two sets of clamping plates 16, the greater the frictional resistance. This increases the tension of the steel wire 7 from the wire hole 9 to the wire frame 19. This structure allows for adjustment of the tension of the steel wire 7, which is beneficial for improving the adjustability of the device.

[0021] Working principle: In the existing twisting machine, the steel wires 7 are prone to loosening during the twisting process. Since the tension of the steel wires 7 cannot be adjusted, the adjustability of the device is poor, affecting the neatness of the steel wire rope 24. By operating the second motor 25 and the first motor 18 simultaneously, the operation of the second motor 25 drives the second fixed rod 21 to rotate. The second fixed rod 21 drives the second take-up wheel 23 on it to rotate circumferentially. The second take-up wheel 23 winds up the steel wire rope 24, realizing that the second take-up wheel 23 pulls the three steel wires 7. The three steel wires 7 are released from the three sets of first take-up wheels 6. The first take-up wheels 6 drive the first fixed rod 4 to rotate, realizing the rapid release of the steel wires 7.

[0022] Simultaneously, the operation of the first motor 18 drives the drive rod 17 to rotate, the drive rod 17 drives the rotating disk 8 to rotate, the rotating disk 8 drives the rotating plate 3 to rotate, the rotating plate 3 drives the three sets of first fixed rods 4 on it to rotate, the first fixed rods 4 drive the first winding wheel 6 on it to rotate, that is, the rotating disk 8 and the three sets of first winding wheels 6 rotate synchronously in a circular motion, and the rotating disk 8 drives the three steel wires 7 to rotate, thus realizing the twisting of the steel wires 7.

[0023] By rotating knob 13, the lead screw 12 is rotated, which in turn drives the two sets of moving plates 14 on it to move synchronously relative to each other. The two sets of moving plates 14 drive the two sets of connecting blocks 15 to move synchronously relative to each other, and the two sets of connecting blocks 15 drive the two sets of clamping plates 16 to move synchronously relative to each other. This reduces the distance between the two sets of clamping plates 16, allowing them to contact the surface of the steel wire 7. When the steel wire 7 is twisted, frictional resistance is generated between the steel wire 7 and the clamping plates 16. The smaller the distance between the two sets of clamping plates 16, the greater the frictional resistance. This increases the tension of the steel wire 7 from the wire hole 9 to the wire frame 19. This structure allows for adjustment of the tension of the steel wire 7, which is beneficial for improving the adjustability of the device.
