Description

Technical Field

[0001] This utility model relates to the field of steel wire rope production technology, specifically to a wire drawing and bundling device for steel wire rope production. Background Technology

[0002] 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. It consists of steel wires, a core, and lubricant. Wire rope is first made by twisting multiple layers of steel wires into strands, and then, with the core as the center, a certain number of strands are twisted into a helical shape. In material handling machinery, it is used for lifting, traction, tensioning, and load bearing. Wire rope has high strength, light weight, stable operation, and is not easily broken suddenly, making it reliable. In 1834, the European Orbert invented the world's first wire rope (bright wire rope). The Tianjin No. 1 Wire Rope Factory, established in 1939, was my country's first metal products enterprise. The production process of wire rope requires the use of wire drawing and bundling devices.

[0003] For example, Chinese Patent (CN211006133U) discloses a wire drawing and bundling device for steel wire rope production, including a main frame. A first servo motor is fixedly installed on the bottom inner wall of the main frame. A first bearing plate is fixedly installed on the left side of the inner wall of the main frame, above the first servo motor. A sub-frame is fixedly installed on the top of the first bearing plate. A drive rod extending into the sub-frame is sleeved on the output shaft of the first servo motor. A first support seat is fixedly installed on the bottom inner wall of the sub-frame. A second support seat is fixedly installed on the bottom inner wall of the sub-frame, around the first support seat. This wire drawing and bundling device for steel wire rope production drives the feeding roller and the wire collecting drum to rotate synchronously through the first and second support seats, avoiding the wire from getting tangled below the wire collecting drum and causing poor wire drawing and bundling quality, thereby improving the production efficiency of feeding.

[0004] In existing technology, after the wire rope is bundled, it is directly wound up by the take-up roller. Due to the huge force during twisting, stress will exist in the wire rope. If the wire rope is directly wound up, it may twist or deform during the winding process. This deformation may cause the wire rope to lose its original structure and performance, affecting subsequent use. If these stresses are not released, the wire rope is prone to breakage or fatigue damage in subsequent use. To address the above problems, a wire drawing and bundling device for wire rope production is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a wire drawing and bundling device for steel wire rope production. It solves the problem that in the current method, the steel wire rope is directly wound by the take-up roller after bundling. Due to the huge force during twisting, there will be stress in the steel wire rope. If the steel wire rope is directly wound, it may be twisted or deformed during the winding process. This deformation may cause the steel wire rope to lose its original structure and performance, affecting subsequent use. If these stresses are not released, the steel wire rope is prone to breakage or fatigue damage in subsequent use.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a wire drawing and bundling device for steel wire rope production, comprising a base plate, a first support frame fixedly connected to the left side of the upper surface of the base plate, a wire tube disposed above the first support frame, a second support frame fixedly connected to the middle of the upper surface of the base plate, a bundling tube rotatably connected above the second support frame via a bearing, a gear ring fixedly connected to the outer side of the right end of the bundling tube, a reducer fixedly installed on the side of the second support frame, a drive gear fixedly connected to the output end of the reducer, the drive gear meshing with the gear ring, and a stress relief component installed on the right side of the second support frame above the base plate.

[0007] Preferably, a first central through hole is provided at the center of the wire tube, and at least six sets of first filament holes are provided inside the wire tube around the first central through hole.

[0008] Preferably, a second central through hole is provided at the center of the bundle tube, and at least six sets of second filament holes are provided inside the bundle tube around the second central through hole. A bundle hole is provided at the right end of the bundle tube, and one end of the second central through hole and the second filament holes are connected to one end of the bundle hole.

[0009] Preferably, the stress relief assembly includes a worktable, the bottom of which is fixedly connected to the upper surface of the base plate, and a first fixed seat is fixedly connected to the front left side of the upper surface of the worktable. At least two first guide wheels are rotatably connected above the first fixed seat via a rotating shaft.

[0010] Preferably, a first guide rod is fixedly connected to both the left and right ends of the rear side of the first fixed seat, and a first movable seat is slidably connected between the two first guide rods through a sliding sleeve. At least two second guide wheels are rotatably connected to the top of the first movable seat through a rotating shaft. A first threaded rod is threadedly connected to the middle of the rear side of the first movable seat. The front end of the first threaded rod is rotatably connected to the rear side of the first fixed seat, and a handwheel for rotation is fixedly connected to the rear end of the first threaded rod.

[0011] Preferably, a second fixed seat is fixedly connected to the rear right side of the upper surface of the workbench, and at least two third guide wheels are rotatably connected to the front side of the second fixed seat via a rotating shaft. Second guide rods are fixedly connected to the left and right sides above the second fixed seat.

[0012] Preferably, a second movable seat is slidably connected between the two second guide rods via a guide sleeve. At least two fourth guide wheels are rotatably connected to the front side of the second movable seat via a rotating shaft. A second threaded rod is threadedly connected to the upper center of the second movable seat. The lower end of the second threaded rod is rotatably connected to the upper surface of the second fixed seat. A handwheel for rotation is fixedly connected to the upper end of the second threaded rod.

[0013] Compared with the prior art, the advantages of this utility model are as follows: This utility model uses a stress relief component, with the first and second guide wheels squeezing from the front and rear directions, and the third and fourth guide wheels squeezing from the top and bottom directions, forming a three-dimensional stress release channel. This can effectively release the torsional stress generated in the wire rope during the bundling process, reducing the accumulation of stress inside the wire rope. This helps to avoid stress concentration areas and reduces the risk of fatigue damage during subsequent use of the wire rope. After eliminating internal stress, the service life of the wire rope is usually extended because without excessive internal stress, the wire rope is less likely to break or suffer fatigue damage during subsequent stretching, bending, and other uses. After stress relief, the structural stability of the wire rope is enhanced, avoiding problems such as twisting and deformation that may occur during direct winding. Attached Figure Description

The second central through hole 8 corresponds to the first central through hole 4 of the guide tube 3, which can guide the central steel wire to continue to be transported. The six sets of second fine wire holes 9 correspond to the first fine wire holes 5, which guide multiple single steel wires to enter simultaneously. The bundle hole 10 at the right end is connected to the second central through hole 8 and the second fine wire hole 9, which can gather the central steel wire and multiple single steel wires and initially form a steel wire rope, realizing precise multi-wire bundling and ensuring the uniformity of the steel wire rope structure.

The front end of the first threaded rod 1407 is rotatably connected to the rear side of the first fixed seat 1402, and a handwheel for rotation is fixedly connected to the rear end of the first threaded rod 1407. Rotating the handwheel of the first threaded rod 1407 drives the first movable seat 1405 to move forward along the first guide rod 1404, adjusting the distance between the first guide wheel 1403 and the second guide wheel 1406.

[0023] Specifically, a second fixed seat 1408 is fixedly connected to the rear right side of the upper surface of the workbench 1401.

[0024] Specifically, a second movable seat 1411 is slidably connected between two second guide rods 1410 via a guide sleeve. At least two fourth guide wheels 1412 are rotatably connected to the front side of the second movable seat 1411 via a rotating shaft.

[0025] Working principle: Multiple steel wires to be bundled are passed through the six sets of first fine wire holes 5 of the guide tube 3 to ensure that the steel wires are evenly arranged and free from tangling; the rope core is passed through the first central through hole 4 of the guide tube 3 and extends synchronously towards the bundling tube 7 with the steel wires. After the steel wires and rope core pass through the guide tube 3, they continue to pass through the corresponding holes in the bundling tube 7. The steel wires pass through the second fine wire holes 9, and the rope core passes through the second central through hole 8; by aligning the holes of the guide tube 3 and the bundling tube 7, the steel wires are guided to be evenly distributed around the rope core, laying the foundation for subsequent twisting and bundling. The reducer 12 is started, and the output end drives the drive gear 13 to rotate; the drive gear 13 meshes with the gear ring 11 at the right end of the bundling tube 7, driving the bundling tube 7 to rotate smoothly around the bearing of the second support frame 6. When the bundling tube 7 rotates, the friction force drives the steel wires and rope core to move synchronously. Under the guidance of the second fine wire holes 9, the steel wires are evenly distributed around the rope core. The wire rope moves in a spiral motion around the core. When the wire and the core reach the bundling hole 10 at the right end of the bundling cylinder 7, they converge and twist under the constraint of the bundling hole 10 to form tightly bonded wire rope strands, completing the bundling process. The bundled wire rope enters the stress relief assembly 14 and first passes between the first guide wheel 1403 and the second guide wheel 1406, where a front-to-back compressive force is applied to the wire rope. The wire rope rolls under the drive of the guide wheels, and the torsional stress is gradually released during the compression. After being compressed from front to back, the wire rope continues to move to the right and passes between the third guide wheel 1409 and the fourth guide wheel 1412, where a vertical compressive force is applied to the wire rope. The bidirectional compression works synergistically to completely release the residual tensile and torsional stress inside the wire rope, preventing twisting and deformation during subsequent winding. The wire rope that has undergone bidirectional compression stress relief is then wound up by the subsequent external winding rollers.
