Description

Technical Field

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

[0002] Steel wire rope is a rope made by twisting multiple layers of steel wires into strands, and then winding a certain number of strands into a spiral shape with the core as the center. Twisting is the core process in steel wire rope production, and its quality directly affects the strength, flexibility, and service life of the steel wire rope.

[0003] Existing wire twisting devices typically consist of a pay-off frame, a traction mechanism, a twisting machine, and a take-up machine. However, in actual production, traditional devices have some shortcomings: 1. Uneven tension control: When multiple steel wires are simultaneously released and twisted, it is difficult to maintain consistent tension, resulting in uneven tension of the steel wires in the strand, generating internal stress and reducing the quality of the finished product.

[0004] 2. Poor lubrication: Lubricating the steel wire before twisting is crucial for reducing friction and extending the life of the wire rope. Traditional methods often involve soaking or simple spraying, resulting in significant waste of lubricant and uneven or insufficient application.

[0005] 3. Complex structure and inconvenient maintenance: Some improved tensioners or lubrication mechanisms have complex structures, occupy a lot of space, and are very inconvenient to repair and replace parts when they fail.

[0006] 4. Splashing and contamination: During high-speed twisting, excess lubricant can easily splash, contaminating equipment and the workshop environment.

[0007] Therefore, there is an urgent need for a wire twisting device that can effectively control wire tension, provide uniform lubrication, and has a compact structure and is easy to maintain. Utility Model Content

[0008] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a wire twisting device for wire rope production that has a reasonable structure, can effectively balance the tension of the wire, achieve uniform and quantitative lubrication, and is easy to maintain.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is: a wire twisting device for wire rope production, comprising a wire feeding frame, a tension adjusting mechanism, a lubrication device, a stranding machine, and a take-up machine arranged sequentially along the wire travel direction. Its innovation lies in: The tension adjustment mechanism includes multiple independently configured tensioner units, each corresponding to a steel wire; each tensioner unit includes a mounting plate, a fixed guide wheel, a movable guide wheel, a tension spring, and an adjusting screw; the fixed guide wheel is fixed to the mounting plate; the movable guide wheel is mounted on a sliding block, which is slidably connected to a slide rail on the mounting plate; the adjusting screw is threadedly connected to the sliding block; the tension spring is connected at both ends to the sliding block and the mounting plate, respectively. The lubrication device includes a housing with a cavity in the upper part. Inside the cavity, a pair of oil-impregnated sponge assemblies are arranged longitudinally. The steel wire passes through the oil-impregnated sponge assemblies. Guide wheels are provided at the upper and lower ends of the oil-impregnated sponge assemblies. The bottom of the cavity is a liquid collection tank. An oil pump is installed outside the housing. The inlet of the oil pump is provided with an inlet pipe that extends into the liquid collection tank. The outlet of the oil pump is provided with an outlet pipe that extends above the oil-impregnated sponge assemblies and is equipped with a dropper. A steel wire inlet is provided on the upper side of the cavity, and a steel wire outlet is provided on the lower side.

[0010] Furthermore, the wire feeding frame is an active wire feeding frame, and its wire feeding reel is driven by a servo motor.

[0011] Furthermore, the groove surfaces of the movable guide wheel and the fixed guide wheel are plated with a hard chrome layer or inlaid with ceramic bushings.

[0012] Furthermore, the oil-impregnated sponge assembly includes a fixed sponge and a movable sponge. The fixed sponge is fixed to the side wall of the cavity, and the movable sponge is fixed to the other side wall of the cavity by a spring. The side wall is threadedly connected to a compression bolt, which compresses the movable sponge.

[0013] Furthermore, the enclosure is made of transparent material or has observation windows on its side walls.

[0014] Furthermore, a guide ceramic eye is provided inside the cavity near the steel wire outlet.

[0015] Furthermore, both the wire inlet and the wire outlet are equipped with sealing elements made of felt or rubber.

[0016] The beneficial effects of this utility model after adopting the above structure are as follows: This invention employs independent and precise tension control: each tensioner unit works independently, and the tension of a single steel wire can be precisely adjusted by rotating the adjusting screw, ensuring that all steel wires have a consistent tension before twisting, which greatly improves the structural uniformity and strength of the strand.

[0017] This invention provides uniform and quantitative lubrication: a steel wire passes through an oil-soaked sponge rich in lubricating oil, ensuring even and continuous absorption of the appropriate amount of lubricating oil, avoiding waste and splashing. The pressure of the sponge on the steel wire can be adjusted via a pressure plate and screw, thereby controlling the amount of oil applied. A sealed enclosure design prevents contamination.

[0018] This utility model features a compact structure and easy maintenance: the tensioner unit has a modular design, simple structure, and intuitive adjustment. The oil-impregnated sponge and guide ceramic eye of the lubrication device are easy to replace, and the transparent box or observation window facilitates observation of the internal condition and oil level. The entire device is easy to maintain and service.

[0019] This invention improves product quality: by ensuring the stability of the two key processes of tension and lubrication, this invention can fundamentally improve the overall performance and service life of the final wire rope product. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0024] like Figure 1-3 As shown, a wire twisting device for wire rope production includes a wire feeding frame 1, a tension adjusting mechanism 2, a lubrication device 3, a strand twister 4, and a take-up machine 5 arranged sequentially along the wire travel direction. The tension adjustment mechanism 2 includes multiple independently arranged tensioner units, each corresponding to a steel wire 6. Each tensioner unit includes a mounting plate 21, a fixed guide wheel 22, a movable guide wheel 23, a tension spring 24, and an adjusting screw 25. The fixed guide wheel 22 is fixed to the mounting plate 21. The movable guide wheel 23 is mounted on a sliding block 26, which is slidably connected to a slide rail 27 on the mounting plate 21. The adjusting screw 25 is threadedly connected to the sliding block 26. The tension spring 24 is connected at both ends to the sliding block 26 and the mounting plate 21, respectively. The tension adjustment mechanism 2 consists of multiple parallel independent tensioner units. The steel wire 6 passes around the fixed guide wheel 22 and the movable guide wheel 23, forming an "S"-shaped path, such as... Figure 2 Rotating the adjusting screw 25 pushes or pulls back the sliding block 26, thereby changing the position of the movable guide wheel 23, and consequently changing the wrap angle and path length of the steel wire 6, achieving precise tension adjustment. The tension spring 24 provides a constant buffering force to absorb minor jumps in the steel wire and maintain stable tension. The surface of the guide wheel can be hardened to improve wear resistance.

[0025] The lubrication device 3 includes a housing 31, with a cavity 32 in the upper part of the housing 31. Inside the cavity 32, a pair of oil-impregnated sponge assemblies 33 are arranged longitudinally. A steel wire 6 passes through the oil-impregnated sponge assemblies 33. Guide wheels 34 are provided at the upper and lower ends of the oil-impregnated sponge assemblies 33. A liquid collection tank 35 is located at the bottom of the cavity 32. An oil pump 36 is installed outside the housing 31. An inlet pipe 37 is provided at the inlet of the oil pump 36, extending into the liquid collection tank 35. An outlet pipe 38 is provided at the outlet of the oil pump 36, extending above the oil-impregnated sponge assemblies and equipped with a drip pipe 39. A steel wire inlet is located on the upper side of the cavity 32, and a steel wire outlet is located on the lower side. The steel wire 6, after tension adjustment, enters the lubrication device 3. Figure 3 As shown, the steel wire 6 enters the sealed box 31 from the inlet, passes through the oil-soaked sponge assembly 33 filled with lubricating oil from top to bottom, and exits from the outlet. The oil-soaked sponge assembly 33 is an adjustable structure, which can adjust the tightness to control the thickness of the oil film adhering to the steel wire. Excess lubricating oil drips into the collection tank 35, and is returned to the outlet pipe 38 by the oil pump 36 through the inlet pipe 37, realizing recycling and saving costs; the collection tank 35 has an oil filling hole on the side for easy oil filling, and an oil drain hole at the bottom for easy discharge of waste oil.

[0026] The wire feeding frame 1 is an active wire feeding frame, and its wire feeding reel is driven by a servo motor to provide initial and relatively stable wire feeding tension. Multiple steel wires 6 are led out from the wire feeding frame 1 and enter the tension adjustment mechanism 2.

[0027] The groove surfaces of the movable guide wheel 23 and the fixed guide wheel 22 are plated with a hard chrome layer or inlaid with ceramic bushings to improve service life.

[0028] The oil-impregnated sponge assembly 33 includes a fixed sponge 331 and a movable sponge 332. The fixed sponge 331 is fixed to the side wall of the cavity, and the movable sponge 332 is fixed to the other side wall of the cavity by a spring 333. The side wall is threadedly connected to a compression bolt 334, which compresses the movable sponge 332. By rotating the compression bolt 334, the movable sponge 332 is compressed and moves closer to the fixed sponge 331, thereby adjusting the tightness between the two sponges and controlling the thickness of the oil film adhering to the steel wire. Excess lubricating oil drips into the collection tank 35 and returns to the outlet pipe 38 via the inlet pipe 37 and oil pump, achieving recycling and saving costs. To facilitate the compression of the movable sponge 332, a pressure plate is provided on the back of the movable sponge 332, which is connected to the inner side wall by a spring.

[0029] To facilitate observation of the internal situation, the enclosure 31 is made of transparent material or has observation windows on the side walls.

[0030] Inside the cavity 32, near the wire outlet, is a guide ceramic eye 7. The smooth inner hole of the ceramic eye scrapes off excess lubricating oil adhering to the surface of the wire, allowing it to return to the oil trough for recycling. This achieves "quantitative lubrication," ensuring a uniform thin oil film on the wire surface while avoiding waste and splashing contamination caused by excessive oil. At the moment the wire exits the lubrication box, the ceramic eye provides a smooth, low-friction transition point, protecting the wire surface from scratches by the metal parts at the box outlet.

[0031] Both the wire inlet and outlet are equipped with felt or rubber seals (not shown in the figure) to prevent lubricating oil leakage.

[0032] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
