Description

Technical Field

[0001] This utility model relates to the field of stranding machine technology, and in particular to a stranding machine for high-speed steel cable braiding. Background Technology

[0002] High-speed steel cable braiding stranding machine is a mechanical device specially used to strand multiple steel wires or steel cables into high-strength steel cables through spiral winding. Its core principle is to use multiple pay-off reels to rotate synchronously, so that single steel wires are wound together at a specific angle and tension to form a steel cable structure with high tensile strength and stability.

[0003] For example, CN209591662U discloses a stranding machine, including a base, on which a wire feeding device, a stranding device, a wire pressing device, a guiding device, and a take-up device are provided. The guiding device includes a vertical guiding mechanism and a horizontal guiding mechanism. The vertical guiding mechanism includes a first guide frame, a first guide wheel, a first movable seat, a second guide wheel, and a first driving assembly. The horizontal guiding mechanism includes a second guide frame fixed to the base, a third guide wheel rotatably connected to the second guide frame via a third rotating shaft, a second movable seat slidably connected to the second guide frame along the width direction of the base, a fourth guide wheel rotatably connected to the second movable seat via a fourth rotating shaft, and a second driving assembly installed on the second guide frame for driving the second movable seat to move.

[0004] However, in existing technologies, the precision of tension control at the winding end is crucial during the operation of stranding machines used for high-speed steel cable braiding. Traditional stranding machines often rely on manual adjustment of the brake belt tension, which is fundamentally incapable of adapting in real-time to the tension fluctuations caused by changes in cable diameter during high-speed winding. Even with the introduction of sensor feedback control, the inherent millisecond-level delay is difficult to eliminate. This results in significant tension differences between the front and rear sections of the cable, severely damaging the cable's torsional resistance, tensile strength, and other mechanical properties. For example, in wind power cables, uneven winding tension due to this technical defect in the stranding machine can easily lead to localized breakage during actual use, posing a safety hazard. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a stranding machine for high-speed steel cable braiding.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-speed steel cable braiding stranding machine, comprising a stranding machine winding mechanism, wherein a wire pressing device, a stranding device, and a wire feeding device are respectively provided on one side of the stranding machine winding mechanism, and a tension adjustment mechanism is fixedly connected to the upper part of the stranding machine winding mechanism, the tension adjustment mechanism comprising a fixed frame, a hydraulic cylinder installed inside the fixed frame, a first mounting frame fixedly connected to the end of the hydraulic cylinder, a guide mechanism fixedly connected to the side of the first mounting frame, a guide mechanism installed at the lower part of the tension adjustment mechanism, an auxiliary mechanism installed on the side of the guide mechanism, the auxiliary mechanism comprising a third mounting frame and a spring, a pressure sensor fixedly connected to the bottom of the third mounting frame, a telescopic rod installed below the pressure sensor, a fourth mounting frame fixedly connected to the bottom of the telescopic rod, a guide pulley installed on the surface of the fourth mounting frame, one end of the spring fixedly connected to the third mounting frame, and the other end of the spring fixedly connected to the fourth mounting frame.

[0007] Preferably, the stranding machine winding mechanism includes a base, with a drive motor and a reducer fixedly connected to the upper part of the base, and a winding roller rotatably connected to the upper part of the base. The output end of the drive motor is fixedly connected to the reducer, and the output end of the reducer is fixedly connected to the winding roller.

[0008] Preferably, the two sides of the first mounting bracket are slidably connected to the fixed bracket.

[0009] Preferably, the guiding mechanism includes a first fixed plate and a guide frame. A servo motor is fixedly connected to the surface of the first fixed plate. A lead screw is fixedly connected to the output end of the servo motor. A lead block is threadedly connected to the surface of the lead screw. The guide frame is fixedly connected to the first fixed plate. The lead block is slidably connected to the guide frame. A second mounting frame is fixedly connected to the surface of the lead block. A second fixed plate is fixedly connected to the surface of the second mounting frame.

[0010] Preferably, a slide rail is fixedly connected to the surface of the first fixing plate, and a slider is slidably connected to the surface of the slide rail, with the slider being fixedly connected to the second fixing plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the winding roller is driven to rotate by the drive motor and reducer in the winding mechanism of the stranding machine to realize the winding of the steel cable. The hydraulic cylinder in the tension adjustment mechanism can automatically adjust the position of the No. 1 mounting frame according to the monitoring data of the pressure sensor in the auxiliary mechanism, and control the tension of the steel cable in real time and accurately. This solves the problem of uneven tension caused by traditional manual adjustment or sensor delay. The spring and telescopic rod of the auxiliary mechanism work together to provide buffer while pressing the steel cable to avoid excessive pressure and damage to the steel cable. The servo motor in the guide mechanism drives the lead screw to move the wire block, the No. 2 mounting frame and the guide pulley horizontally to realize the neat arrangement of the steel cable on the surface of the winding roller. This effectively improves the mechanical properties and appearance quality of the steel cable, reduces manual intervention and improves production efficiency and automation level. 2. In this utility model, the first fixing plate and the guide frame provide stable support for components such as the lead screw and lead block. The servo motor drives the lead screw to rotate, causing the lead block to slide along the guide frame, thereby enabling the second mounting frame and the second fixing plate to move horizontally, ensuring that the guide pulley accurately guides the steel cable arrangement. At the same time, the cooperation between the slide rail and the slider further limits the movement trajectory of the auxiliary mechanism when the second fixing plate drives it to move horizontally, avoiding deviation and shaking, ensuring that the steel cable winding process is stable and orderly, reducing the probability of problems such as steel cable tension fluctuation and wire arrangement disorder caused by component shaking, and improving the steel cable winding quality and production efficiency.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1: As Figures 1-5 As shown, this utility model provides a high-speed steel cable braiding stranding machine, including a stranding machine winding mechanism 1. A wire pressing device, a stranding device, and a wire feeding device are respectively arranged on one side of the stranding machine winding mechanism 1. A tension adjustment mechanism 2 is fixedly connected to the upper part of the stranding machine winding mechanism 1. The tension adjustment mechanism 2 includes a fixed frame 21, a hydraulic cylinder 22 installed inside the fixed frame 21, and a first mounting frame 23 fixedly connected to the end of the hydraulic cylinder 22. A guide mechanism 3 is fixedly connected to the side of the first mounting frame 23. The guide mechanism 3 is installed at the lower part of the tension adjustment mechanism 2, and an auxiliary mechanism 4 is installed on the side of the guide mechanism 3. The auxiliary mechanism 4 includes a third mounting frame 41 and a spring 44. The bottom of the third mounting frame 41 is fixed... A pressure sensor 42 is fixedly connected, and a telescopic rod 43 is installed at the lower part of the pressure sensor 42. A fourth mounting bracket 45 is fixedly connected to the bottom of the telescopic rod 43. A guide pulley 46 is installed on the surface of the fourth mounting bracket 45. One end of the spring 44 is fixedly connected to the third mounting bracket 41, and the other end of the spring 44 is fixedly connected to the fourth mounting bracket 45. The stranding machine winding mechanism 1 includes a base 11. A drive motor 12 and a reducer 13 are fixedly connected to the upper part of the base 11, and a winding roller 14 is rotatably connected to the upper part of the base 11. The output end of the drive motor 12 is fixedly connected to the reducer 13, and the output end of the reducer 13 is fixedly connected to the winding roller 14. The two sides of the first mounting bracket 23 are slidably connected to the fixed bracket 21.

[0017] The specific settings and functions of this embodiment are described in detail below. The steel cable is braided by the wire pressing device, wire twisting device and wire feeding device set on one side of the stranding machine winding mechanism 1. The winding roller 14 is driven to rotate by the drive motor 12 and the reducer 13 to wind up the braided steel cable. The steel cable is pressed by the auxiliary mechanism 4. The tension pressure of the steel cable is monitored by the pressure sensor 42. When the tension pressure is too high or too low, the first mounting frame 23 is moved up or down by the hydraulic cylinder 22 to automatically adjust the tension of the steel cable by the auxiliary mechanism 4. The guide pulley 46 limits and guides the steel cable during winding. The servo motor 32 drives the lead screw 34 to rotate, which in turn drives the wire block 35 and the second mounting bracket 36 to move, thereby driving the guide pulley 46 to move horizontally, so that the steel cable can be neatly arranged on the surface of the winding roller 14.

[0018] The winding mechanism 1 of the stranding machine drives the winding roller 14 to rotate through the drive motor 12 and reducer 13, thereby achieving the winding of the steel cable. The hydraulic cylinder 22 in the tension adjustment mechanism 2 can automatically adjust the position of the first mounting frame 23 according to the monitoring data of the pressure sensor 42 in the auxiliary mechanism 4, and control the tension of the steel cable in real time and accurately, thus solving the problem of uneven tension caused by traditional manual adjustment or sensor delay. The spring 44 and the telescopic rod 43 of the auxiliary mechanism 4 cooperate to provide buffer while pressing the steel cable, so as to avoid damage to the steel cable due to excessive pressure. The servo motor 32 in the guide mechanism 3 drives the lead screw 34, which drives the wire block 35, the second mounting frame 36 and the guide pulley 46 to move horizontally, so as to achieve the neat arrangement of the steel cable on the surface of the winding roller 14, effectively improving the mechanical properties and appearance quality of the steel cable, reducing manual intervention, and improving production efficiency and automation level.

[0019] Example 2: Figures 1-5 As shown, the guide mechanism 3 includes a first fixed plate 31 and a guide frame 33. A servo motor 32 is fixedly connected to the surface of the first fixed plate 31. A lead screw 34 is fixedly connected to the output end of the servo motor 32. A lead screw block 35 is threadedly connected to the surface of the lead screw 34. The guide frame 33 is fixedly connected to the first fixed plate 31. The lead screw block 35 is slidably connected to the guide frame 33. A second mounting bracket 36 is fixedly connected to the surface of the lead screw block 35. A second fixed plate 37 is fixedly connected to the surface of the second mounting bracket 36. A slide rail 38 is fixedly connected to the surface of the first fixed plate 31. A slider 39 is slidably connected to the surface of the slide rail 38. The slider 39 is fixedly connected to the second fixed plate 37.

[0020] The overall effect of this embodiment is that, during the up-and-down movement of the first mounting bracket 23, the movement of the first mounting bracket 23 is limited by the fixed bracket 21, thereby improving the stability of the first mounting bracket 23 and the first fixed plate 31 during the lifting and lowering process. When the second fixed plate 37 drives the auxiliary mechanism 4 to move horizontally, the slider 39 slides along the slide rail 38, thereby limiting the movement of the second fixed plate 37 and improving the stability of the auxiliary mechanism 4 during the movement.

[0021] The first fixed plate 31 and guide frame 33 provide stable support for components such as the lead screw 34 and lead block 35. The servo motor 32 drives the lead screw 34 to rotate, causing the lead block 35 to slide along the guide frame 33, thereby enabling the second mounting frame 36 and the second fixed plate 37 to move horizontally, ensuring that the guide pulley 46 accurately guides the steel cable arrangement. At the same time, the cooperation of the slide rail 38 and the slider 39 further limits the movement trajectory of the auxiliary mechanism 4 when the second fixed plate 37 drives it to move horizontally, preventing deviation and shaking. The fixed frame 21 plays a restraining role when the first mounting frame 23 moves up and down with the hydraulic cylinder 22, reducing the shaking amplitude. These structural designs work together to effectively improve the stability of the first mounting frame 23 and the first fixed plate 31 during lifting and lowering, as well as the horizontal movement of the auxiliary mechanism 4, ensuring a smooth and orderly steel cable winding process, reducing the probability of problems such as steel cable tension fluctuations and cable routing disorder caused by component shaking, and improving the quality and efficiency of steel cable winding.

[0022] The device is used and works as follows: The steel cable is braided by the wire pressing device, wire twisting device and wire feeding device set on one side of the wire winding mechanism 1. The winding roller 14 is driven to rotate by the drive motor 12 and the reducer 13 to wind up the braided steel cable. The steel cable is pressed by the auxiliary mechanism 4. The tension of the steel cable is monitored by the pressure sensor 42. When the tension is too high or too low, the first mounting frame 23 is moved up or down by the hydraulic cylinder 22 to automatically adjust the tension of the steel cable by the auxiliary mechanism 4. The guide pulley 46 limits and guides the steel cable during winding. The servo motor 32 drives the lead screw 34 to rotate, which in turn drives the wire block 35 and the second mounting bracket 36 to move, thereby driving the guide pulley 46 to move horizontally, so that the steel cable can be neatly arranged on the surface of the winding roller 14. During the up-and-down movement of the first mounting bracket 23, the movement of the first mounting bracket 23 is limited by the fixed bracket 21, which improves the stability of the first mounting bracket 23 and the first fixed plate 31 when they are raised and lowered. When the second fixed plate 37 drives the auxiliary mechanism 4 to move horizontally, the slider 39 slides along the slide rail 38 to limit the movement of the second fixed plate 37, which improves the stability of the auxiliary mechanism 4 when it moves.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
