Description

Technical Field

[0001] The present application relates to the technical field of wire rope processing equipment, and in particular to a double-twisting machine for wire rope processing. Background Art

[0002] As core equipment for producing high-strength steel wire rope, double-twist machines play a vital role in modern industry. With the rapid development of modern industry, demand for high-strength steel wire rope has increased dramatically in numerous sectors, such as tires, aviation, and construction. This has led to more stringent standards for the performance and product quality of double-twist machines. Double-twist machines utilize a double-twist process to precisely twist multiple strands of steel wire. Their widespread application has significantly driven progress in related industries and significantly improved product quality and safety. For example, in the construction sector, high-strength steel wire rope provides reliable support for large structures, ensuring their stability. Double-twist machines also play a key role in other areas, promoting the efficient operation of the entire industrial system.

[0003] In the field of wire rope processing, basic twisting processes and equipment have traditionally been used to achieve the twisting of wire ropes. The twisting process of wire ropes is generally completed with the help of traditional twisting mechanisms, which achieve the initial twisting of the steel wires through simple rotational movements. In terms of tension control, more basic adjustment methods are often used, such as manual adjustment or simple mechanical adjustment devices to try to adjust the tension during the twisting process. However, these methods often lack sufficient accuracy and stability. In terms of shaping, conventional methods mostly rely on natural cooling or simple molds for shaping, lacking effective shaping methods specifically tailored to the characteristics of wire rope twisting. Moreover, there is no perfect method to accurately control the tension changes of the wire rope during the transition stage of the twisting process.

[0004] Existing double-twist machines have significant shortcomings. During the double-twist process, the lack of effective shaping methods results in a high risk of rebound deformation of the wire rope, which severely impacts its final shape and quality. Furthermore, inaccurate tension control during the transition phase between the second twist and the final twist results in inconsistent tension before and after the twist. This not only affects the winding quality of the wire rope but also negatively impacts its subsequent use, reducing its reliability and stability in practical applications. Summary of the Invention

They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the invention.

[0031] The present application discloses a double twisting machine for processing steel wire ropes. Figure 1 and Figure 2The double-twisting machine for wire rope processing provided in the embodiment of the present application includes a pay-off mechanism, a primary twisting mechanism 20, an over-twisting mechanism and a wire arranging mechanism, wherein the pay-off mechanism is responsible for paying out the steel wire, the primary twisting mechanism 20 twists the steel wire into strands, the over-twisting mechanism performs a second twist on the primary twisted strands to form double-twisted strands, and the wire arranging mechanism arranges the twisted steel wire rope, thereby achieving efficient twisting and orderly wire arranging of the steel wire rope, and ensuring the processing quality of the steel wire rope.

[0032] The pay-off mechanism includes a first strand reel 11, a second strand reel 12, a core wire box 13, a wire feed frame 14, and a wire distribution tray 15. The first and second strand reels 11, 12 are used to wind the wire, which is then transferred outward from the first and second strand reels 11, 12 via a driven guide pulley in the middle. The core wire box 13 is a closed box structure with a wire outlet located in the direction of the wire outlet. The core wire box 13 protects the core wire and prevents dust. The core wire box 13 is placed between the first and second strand reels 11, 12, providing a basic routing position for the strands of wire wrapped around the core wire. A core wire wheel 131 is rotatably mounted on a bearing at the outlet end of the core wire box 13. This wheel is used to guide the core wire out of the core wire box 13 in an orderly manner. Made of rubber, the wheel has a certain degree of elasticity, allowing for better contact with the core wire, allowing the core wire in the core wire box 13 to be smoothly discharged through the wheel 131. The wire feed frame 14 is annular in shape, and a plurality of wire guide pulleys 141 are fixed to its inner wall by bolts. The plurality of wire guide pulleys 141 are installed along the inner wall of the annular wire feed frame 14, so that the plurality of wire guide pulleys 141 are distributed in an annular shape as a whole. The outer circumference of the wire guide pulley 141 is provided with an arc-shaped groove adapted to the steel wire to prevent the steel wire from escaping from the wire guide pulley 141 during transportation. The plurality of wire strands pass through the plurality of wire guide pulleys 141 respectively, while the core wire passes directly through the middle position of the wire feed frame 14. The arrangement of the wire feed frame 14 changes the transport trajectory of the plurality of wire strands from a straight line to a transport trajectory distributed in an annular pattern with the core wire as the center.

[0033] The distribution disk 15 is arranged in the outlet direction of the wire feed frame 14, and is provided with a plurality of strand holes 152. These strand holes 152 are arranged in a circular ring shape, and the strand holes 152 correspond one-to-one with the strand guide wheels 141, and the apertures match the diameter of the steel wire. A core wire hole 151 is provided in the middle of the distribution disk 15. This structure allows the strands of steel wire and the core wire to be arranged in order, preparing for subsequent twisting. The layout of the strand holes 152 and the core wire holes 151 opened on the distribution disk 15 corresponds to the twisting size of the primary twisting mechanism 20, so that the distance between the core wire and the strand delivered to the primary twisting mechanism 20 is more compact. This setting is used to reduce the force of the primary twisting mechanism 20 when twisting the steel wire.

[0034] The primary twisting mechanism 20 adopts a conventional structural design. Its core task is to twist the several strands released by the pay-off mechanism around the core wire to complete the initial twisting process. In this process, multiple strands are wound around the core wire in a specific spiral direction and twist pitch, gradually forming a wire rope with a preliminary structure. This preliminary twisting prepares for the subsequent secondary twisting by the over-twist mechanism, ensuring that the final produced wire rope has a stable structure and performance. A screw adjustment mechanism 30 is provided at the bottom of the primary twisting mechanism 20. The screw adjustment mechanism 30 consists of a screw, a nut and a drive motor. The screw is driven to rotate by the drive motor, and the nut cooperates with the screw and is connected to the primary twisting mechanism 20. When the screw rotates, the nut moves on the screw, thereby driving the primary twisting mechanism 20 to move. By adjusting the distance between the primary twisting mechanism 20, the pay-off mechanism and the over-twist mechanism, the tension is controlled during the twisting process of the wire rope. When twisting thicker wire ropes, due to their thicker and heavier strands, greater tension is required to ensure a tight twist. In this case, the screw adjustment mechanism 30 can be used to increase the distance between the primary twist mechanism 20 and the overtwist mechanism to increase the strand tension. When twisting thinner wire ropes, the distance can be appropriately reduced to reduce the tension and avoid breakage or damage to the strands due to excessive tension. This allows for effective tension control to accommodate strands of varying thicknesses.

[0035] Reference Figure 3 and Figure 4The overtwist mechanism comprises a U-shaped frame 41, a rotating drum 42, a first overtwist wheel 421, a second overtwist wheel 422, an overtwist guide wheel 43, and an overtwist drive assembly. The rotating drum 42 is cylindrical in shape and is typically made of metal. It has a mounting slot inside and is mounted via bearings in bearing blocks on either side of the U-shaped frame 41. It can rotate about its axis, enabling the rotating drum 42 to be rotatably mounted on the U-shaped frame 41. The first and second overtwist wheels 421, 422 are rotatably mounted within the mounting slots, with their axles mounted on the side walls of the slots via bearings. The overtwist guide wheel 43 is fixed to either side of the U-shaped frame 41 via brackets. The overtwist drive assembly comprises an overtwist drive motor 44, a drive belt 45, and pulleys 46. The pulleys 46 are fixed to the output shaft of the overtwist drive motor 44 and the ends of the rotating drum 42, respectively. The drive belt 45 is tensioned between the two pulleys 46. When the drive motor is operating, the belt drives the rotating drum 42 to rotate within the U-shaped frame 41. The primary twist strands pass around the first and second over-twist pulleys 422 in a figure-eight trajectory. This design leverages the centrifugal force of the rotating drum 42 and the guiding action of the over-twist pulleys to ensure uniform stress distribution during the secondary twisting process. Specifically, the strands first pass around the first over-twist pulley 421, where the rotation of the rotating drum 42 generates centrifugal force, pulling the strands outward. The strands then return and pass around the second over-twist pulley 422, where they are again stressed and redirected, forming a symmetrical figure-eight trajectory. This symmetrical path evenly distributes the tensile and torsional forces on the strands during rotation, avoiding structural defects caused by localized stress concentration and significantly improving the twisting precision and mechanical properties of the double-twist strands.

[0036] The wire arrangement mechanism includes a first main steering disc 81, a second main steering disc 82, a fixed plate, a shaping assembly, a tensioning assembly and a wire arrangement assembly. The first main steering disc 81 and the second main steering disc 82 are rotatably connected to the first secondary guide wheel 811 and the second secondary guide wheel 821 through a rotating shaft. The guide disc and the guide wheel can guide the direction of the wire rope. The fixed plate plays a role of connection and support. The shaping assembly includes a support 52 fixedly mounted on the fixed plate and a plurality of shaping guide wheels 51. The shaping guide wheels 51 are mounted on the support 52. The plurality of shaping guide wheels 51 are arranged in two rows. The wheel surface is arc-shaped, and the curvature is adapted to the outer contour of the wire rope to ensure uniform pressure on the wire rope and prevent the wire rope from rebounding and deforming. The tensioning assembly includes a tensioning wheel bracket 63 and a first tensioning wheel 61 and a second tensioning wheel 62 arranged in parallel up and down and with adjustable spacing, which are mounted on the tensioning wheel bracket 63. By adjusting the spacing between the first tensioning wheel 61 and the second tensioning wheel 62, the tension of the wire rope is ensured to be uniform front and back. The wire arrangement assembly includes a take-up wheel 71 and a wire arrangement wheel 72. A servo motor and a screw nut mechanism 74 are provided on the fixed plate for driving the wire arrangement wheel 72 to move. When the servo motor is working, the screw nut mechanism 74 drives the wire arrangement wheel 72 to move, thereby realizing orderly wire arrangement of the wire rope.

[0037] The working principle of the embodiment of the present application is as follows: This double-twist machine for wire rope processing effectively solves the problems existing in existing double-twist machines through the coordinated operation of various mechanisms. The pay-off mechanism ensures the orderly pay-out of the steel wire and core wire, the primary twist mechanism 20 performs the initial twisting, and the screw adjustment mechanism 30 controls the twisting tension.

[0038] After the initial twisting, the steel rope will first be guided by the first sub-guide wheel 811 on the first main steering disc 81, so that the initial twisted steel rope passes through the second sub-guide wheel 821 and passes through the opening in the middle of the second main steering disc 82 toward the tensioning wheel group. After the steel rope is wrapped around the first tensioning wheel 61 group and the second tensioning wheel 62 group for several turns, it is guided into the rotating drum 42 through the over-twisting guide wheel 43. The twisting accuracy of the steel rope is improved through the unique figure-8 twisting path.

[0039] After secondary twisting, the finished wire is guided to the shaping assembly by a reversing pulley 91 fixed to a fixed plate. The wire then passes through the shaping guide pulley 51, which applies lateral force from both sides of the wire to prevent it from rebounding and deforming. The shaped wire is then wound around the tensioning pulley several times again to ensure uniform tension. Finally, the wire is routed through the cable routing assembly for orderly cable routing.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
