Abstract
Description
Technical Field
[0001] The utility model relates to a lever - type wet - drawn steel wire anti - bamboo - joint device and a steel cord production device, belonging to the technical field of wet - drawn steel wire drawing. Background Art
[0002] In the production process of steel cord, wet - drawn steel wire drawing is a key step, which involves drawing brass steel wire through multiple passes to make it reach the required diameter and performance to meet the requirements of manufacturing steel cord products. However, in this process, the steel wire may have a so - called "bamboo - joint" phenomenon, that is, uneven protrusions similar to bamboo joints appear on the surface of the steel wire. The appearance of such unqualified products is mainly caused by the resonance of the steel wire when passing through the outlet of the wire - drawing die.
[0003] In the existing technology, in order to reduce this resonance phenomenon, a simple method is adopted: hanging a bent steel wire at the outlet of the finished die. This method attempts to absorb or reduce vibration through the hanging steel wire, thereby reducing the generation of bamboo joints. However, this method has the following problems: First, the bending operation of the hanging steel wire is carried out manually, so it is difficult to ensure the consistency of each operation, resulting in the instability of the anti - bamboo - joint effect. Second, if the bent steel wire is too short, it may not be able to effectively absorb vibration, so the anti - bamboo - joint effect is poor; if it is too long, the end of the steel wire may be immersed in the lubricating fluid, which not only affects the anti - bamboo - joint effect but also may cause pollution to the steel wire itself. Third, since the steel wire will adhere to oil and dirt after running for a period of time, it needs to be replaced regularly, which not only increases the workload of maintenance but also increases the material loss and cost. Fourth, the requirements of manual operation and regular replacement reduce the continuity and efficiency of the production process. Summary of the Utility Model
[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a lever - type wet - drawn steel wire anti - bamboo - joint device and a steel cord production device, which can reduce or eliminate the bamboo - joint phenomenon generated during the drawing process of the steel wire, improve the production efficiency and product quality. By using the lever principle and adjustable counterweights, this device can more precisely control the pressure applied to the steel wire to meet the requirements of steel wires with different diameters, while reducing the maintenance cost and improving the operation consistency.
[0005] To solve the above - mentioned technical problems, the utility model is implemented by adopting the following technical solutions:
[0006] A lever - type wet - drawn steel wire anti - bamboo - joint device includes a fixed shaft and a machine tool steel wire.

[0026] See Figure 1 and Figure 2, this utility model introduces a lever - type wet - drawn steel wire anti - bamboo - joint device. This device aims to reduce or eliminate the bamboo - joint phenomenon generated during the wire drawing process through a more standardized and automated method, improving production efficiency and product quality. The structure of the device includes a fixed shaft 1 and a machine tool steel wire 11. The fixed shaft 1 is the core part of the entire device. By fixing the second fastener 2 to the machine tool, the stability of the device is ensured. The second fastener 2 can be a screw, such as a round - head screw, a flat - head screw, etc.
[0027] One end of the fixed shaft 1 is connected to the first lever arm 5, and the other end is connected to the second lever arm 6. The shapes and functions of the two lever arms are different, and the second lever arm 6 is on the side facing the machine tool steel wire 11.
[0028] Furthermore, the fixed shaft 1 has a hole, and the first lever arm 5 and the second lever arm 6 rotate around the fixed shaft 1 to achieve lever - type swinging.
[0029] To implement the lever mechanism, a union nut 3 is provided on the fixed shaft 1 at a preset gap. This design allows the fixed shaft 1 to swing around the second fastener 2. The second fastener 2 is sleeved with a first sleeve 4, and the first sleeve 4 is used to adjust the distance between the fixed shaft 1 and the machine tool to ensure the proper position of the lever arm and the effective transmission of the acting force.
[0030] Furthermore, the first lever arm 5 is thread - connected to a counterweight 7 through a first fastener 8. The first fastener 8 can be a screw, such as a round - head screw, a flat - head screw, etc. The second lever arm 6 has a fixed bending angle, which is preset. Specifically, the bending angle of the second lever arm 6 is set to be less than 90°, which can prevent the lever arm from flipping to the vertical state and becoming ineffective. By changing the position of the counterweight 7 on the first lever arm 5, the pressure exerted by the second sleeve 9 on the wire on the second lever arm 6 is changed.
[0031] The other end of the second lever arm 6 is connected to an adjustable second sleeve 9 through a third fastener 10. The second sleeve 9 is made of a cemented carbide material, and there are preset gaps at both ends of the second sleeve 9, so that the second sleeve 9 can rotate on the third fastener 10 to avoid hard abrasion of the wire.
[0032] Further, by adjusting the first fastener 8, the position of the counterweight 7 on the first lever arm 5 is changed, and then the pressure exerted by the second sleeve 9 on the machine tool steel wire 11 is changed to meet the production requirements of steel wires with different diameters.
[0033] The above - introduced anti - bamboo - joint device can more precisely control the pressure exerted on the machine tool steel wire 11 by using the lever principle and an adjustable counterweight 7 to adapt to the needs of steel wires with different diameters, while reducing maintenance costs and improving operational consistency. Embodiment 2
[0034] Refer to Figure 1 , the mako 12 and the wire passing wheel 13 are key components through which the steel wire passes during the drawing process. In the embodiment of the present utility model, one end of the machine tool steel wire 11 is connected to the mako 12, and the other end is connected to the wire passing wheel 13. The machine tool steel wire 11, the mako 12, and the wire passing wheel 13 are in the same plane.
[0035] During the production process of the steel cord, in order to solve and eliminate the resonance of the machine tool steel wire 11 between the mako 12 and the wire passing wheel 13 caused by machine tool vibration, the second sleeve 9 made of cemented carbide material assembled on the second force arm 6 abuts against the machine tool steel wire 11 between the mako 12 and the wire passing wheel 13, applying a certain pressure to the machine tool steel wire 11, thereby solving the above-mentioned resonance problem and avoiding the generation of unqualified steel wire bamboo joints, that is, meeting the requirements of machine tool steel wires 11 with different diameters.
[0036] Furthermore, the lever-type wet drawing steel wire anti-bamboo joint device is installed on the box body near the machine tool steel wire 11. In the embodiment of the present utility model, this device is generally assembled on the box body on the left side of the machine tool steel wire 11. Embodiment 3
[0037] A steel cord production device, characterized in that the lever-type wet drawing steel wire anti-bamboo joint device described in Embodiment 1 and Embodiment 2 is used for wet drawing steel wire drawing production.
[0038] Working principle: The anti-bamboo joint device introduced in the present utility model is composed of a fixed shaft 1, a force arm, a counterweight 7, a sleeve, etc., forming a lever structure that can swing freely around the fixed shaft 1. By adjusting the position of the counterweight 7 on the first force arm 5, the pressure exerted by the device on the machine tool steel wire 11 can be adjusted to meet the production requirements of steel wires with different diameters. One end of the second force arm 6 is bent downward at a certain angle to prevent the device from flipping and failing during use. The end of the second force arm 6 is assembled with a second sleeve 9, which is closely attached to the machine tool steel wire 11. When the wet drawing machine tool runs, the pressure exerted by this device on the machine tool steel wire 11 can eliminate the resonance phenomenon of the steel wire caused by machine tool vibration and avoid the generation of unqualified bamboo joints.
[0039] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
