Description

Technical Field

[0001] The invention relates to the field of cable accessories, in particular to a cable and conductor bending single-line straightening device. Background Art

[0002] During the testing process for wire products, twisted, spirally bent wires need to be untwisted and straightened to test properties like resistivity, tensile strength, and elongation. When spot-checking single-wire resistivity, elongation, and tensile strength for conductors, shielding, and armor, twisted, deformed wires also need to be straightened. Currently, cables and wires are typically untwisted manually, and then straightened using a wooden hammer. This method is not only time-consuming and labor-intensive, but also produces poor straightening results, impacting testing efficiency and accuracy.

[0003] Therefore, those skilled in the art are committed to developing a cable and wire bending and single-line straightening device that is simple to operate, has low manufacturing cost and can greatly improve work efficiency. Summary of the Invention

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, in the description of the present invention, the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific manner. Therefore, they should not be construed as limiting the present invention. The terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] like Figure 1-3 As shown, a single-line straightening device for bending cables and wires includes a base 1. The base 1 serves as an installation base, on which a fixed base 2 and a sliding base 3 located on the same horizontal plane are spaced apart. The main purpose of arranging the fixed base 2 and the sliding base 3 on the same horizontal plane is to improve the straightening accuracy and avoid lateral force interference. Furthermore, the fixed base 2 is fixedly connected to the base 1, while the sliding base 3 slides with the base 1. In order to achieve the above-mentioned sliding cooperation, the base 1 is provided with at least one guide rail 4 that cooperates with the sliding base 3. The guide rail 4 extends along the direction of travel of the sliding base 3. The provision of the guide rail 4 facilitates the sliding of the sliding base 3 on the base 1 while also playing a guiding role. In this embodiment, two guide rails 4 are provided, and other embodiments may also provide other numbers of guide rails 4 according to actual needs.

[0024] In this embodiment, a rotator 31 is rotatably mounted within the sliding base 3. The sliding base 3 provides a mounting base for the rotator 31, and the rotational engagement can be achieved through bearings or a clearance fit. In this embodiment, the rotator 31 is cylindrical and has a clearance fit within the sliding base 3, allowing the rotator 31 to rotate freely within the sliding base 3. Furthermore, a first locking head 311 is provided at one end of the rotator 31 near the fixed base 2. The first locking head 311 is provided with a first locking bolt 311a. The fixed base 2 is provided with a second locking head 313 corresponding to the first locking head 311. The second locking head 313 is provided with a second locking bolt 313a. The first locking head 311 and the second locking head 313 respectively secure the two ends of the spirally bent single wire to ensure that the bent single wire will not flip or shift after being clamped. The provision of the first locking bolt 311a and the second locking bolt 313a allows the tightness of the two ends of the bent single wire to be adjusted. Furthermore, a handle 314 is provided at one end of the rotator 31 away from the first locking head 311 , and the rotator 31 can be easily rotated by the handle 314 .

[0025] In this embodiment, a ratchet 312 is provided on the rotator 31, and a pawl (not shown in the figure) that cooperates with the ratchet 312 is provided on the sliding base 3. By arranging the ratchet 312 and the pawl, the rotator 31 can only rotate in one direction compared to the sliding base 3. This arrangement can effectively ensure that during the single-line straightening process, rebound caused by the internal stress of the bent single line will not occur.

[0026] In this embodiment, a traction rope 52 is connected to the sliding base 3. A counterweight device 53 is attached to the end of the traction rope 52 away from the sliding base 3, located at a lower level than the sliding base 3. The counterweight device 53 can be one or more of weights, weight plates, sand, or dumbbells. By attaching a counterweight to the traction rope 52, the sliding base 3 is pulled, tightening the spirally curved single wire. Furthermore, a pulley seat 5 is provided at the end of the base 1 away from the fixed base 2. A fixed pulley 51 is mounted on the pulley seat 5. The fixed pulley 51 converts the vertical pulling force of the counterweight device 53 into a horizontal pulling force.

[0027] In this embodiment, a laser pen 6 is provided on one end of the fixed base 2 near the sliding base 3. Laser light emitted by the laser pen 6 is used to determine whether the bending line is completely straightened. Furthermore, a scale 7 is provided on the base 1. The scale 7 is marked with the required gauge lengths of several specimens, facilitating marking the required gauge lengths of the specimens on the bending line.

[0028] This application has a novel structure and is easy to operate. The single wire straightened by this application can effectively eliminate spiral bending and internal stress while avoiding secondary deformation. Moreover, this application is reusable, which greatly reduces labor and material costs, improves straightening efficiency, and has great market promotion value.

[0029] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should be within the scope of protection defined by the claims.
