Description

Technical Field

[0001] The present application relates to the field of cable equipment processing, and in particular to a bidirectional double-pressure wheel wire twisting device. Background Art

[0002] In cable manufacturing, cable torque and stranding technology have always been key to improving cable performance, ensuring safety, and increasing production efficiency. With the continuous development of deep-sea exploration, underwater operations, power transmission, and communication technologies, higher requirements are being placed on cable torque balance and stranding processes.

[0003] Stranding is a process in which multiple bare wires or conductors are twisted together in a spiral to create a twisted cable. This technology not only improves cable flexibility, reliability, and strength, but also facilitates installation and maintenance. In the cable manufacturing industry, stranding is widely used in the production of both bare wire and insulated wire and cable.

[0004] The core of the stranding process lies in controlling the twist pitch and twist coefficient. The twist pitch is the distance from the first helical intersection to the point where it reappears within a strand, while the twist coefficient is the ratio of the actual length of the strand to the twist length. By adjusting the twist pitch and twist coefficient, the properties of the strand, such as flexibility, strength, and flexural properties, can be optimized.

[0005] In the existing technology, the success of the twisting process is related to the torque of the cable. The adjustment of the torque of the cable will affect the twisting efficiency. Therefore, how to control the torque to facilitate efficient twisting of the cable is an important technical problem that needs to be solved urgently. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. It is understood that the drawings are only provided for reference and illustration purposes and are not used to limit the present application. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0032] Specifically, if Figure 1 As shown, the embodiment of the present application provides a bidirectional double-pressure wheel wire stranding device, the device body is provided with a roller 100, the roller 100 is provided with a support plate 110, and the support plate 110 is provided with a plurality of guide holes 111 in an annular shape. In the embodiment of the present application, there are 30 guide holes 111, and each of the 30 guide holes 111 is a group of 6, which are evenly divided into 5 groups. The guide holes 111 pass through the support plate 110, making it convenient to pass the cable through the guide holes 111 through the support plate 110. Guide wheel assemblies 200 are provided on both sides of the support plate 110. The guide wheel assemblies 200 are installed corresponding to the positions of the guide holes 111. Specifically:

[0033] The guide wheel assembly 200 includes a guide plate 210, a fixed pulley 220 and an adjusting pulley 230. The fixed pulley 220 is fixedly mounted on the guide plate 210 via an axis, and the fixed pulley 220 rotates via the axis. An annular groove 221 is provided on the fixed pulley 220. The annular groove 221 can limit the cable and move the cable along the cable channel 300. The adjusting pulley 230 is arranged on one side of the fixed pulley 220. In the embodiment of the present application, it is specifically arranged on the side of the fixed pulley 220 away from the center of the support plate 110.

[0034] The adjusting pulley 230 is provided on the guide plate 210 and is movably mounted on the guide plate 210, specifically:

[0035] An adjusting slot 211 is provided on the guide plate 210 corresponding to the position of the adjusting pulley 230, and a fixed shaft 410 is provided on the adjusting pulley 230. The fixed shaft 410 is located in the adjusting slot 211 and moves linearly in the adjusting slot 211, so that the position of the adjusting pulley 230 can be adjusted, thereby adjusting the width of the cable channel 300. The process of adjusting the pulley 230 is carried out by an adjusting bolt 420, and the adjusting bolt 420 is threadedly connected to the guide plate 210. Specifically, an adjusting hole 212 is provided on the guide plate 210, and the adjusting hole 212 is connected to the adjusting slot 211. The adjusting bolt 420 enters the adjusting slot 211 through the adjusting hole 212, and the adjusting bolt 420 is located at one end of the adjusting slot 211 and is connected to the fixed shaft 410. When the adjusting bolt 420 rotates in the adjusting hole 212. The adjusting bolt 420 drives the fixing shaft 410 to move in the adjusting slot 211 , and the moving direction is the radial direction of the supporting plate 110 .

[0036] In the embodiment of the present application, the support plate 110 is circular in design, and the fixed shaft 410 and the adjusting bolt 420 together constitute an adjusting member 400 .

[0037] Based on the above structure, when the cable passes through the cable channel 300, one side of the cable is squeezed and pushed by the adjusting pulley 230 to perform torque operation on the cable, and the cable is torqued to a specified angle. The setting of the angle is operated by determining the position of the adjusting pulley 230, so that the torqued cable can be easily twisted into the required cable.

[0038] In the above process, the fixed pulley 220 and the adjusting pulley 230 in the guide wheel assembly 200 are respectively set to two, such as Figure 2 As shown, the cable channel 300 between the fixed pulley 220 and the adjusting pulley 230 is adjusted twice before passing through the guide hole 111 and is adjusted twice again after passing through the guide hole 111, and each set of guide wheel assemblies 200 can be adjusted by the adjusting bolt 420 to perform torque operation on the cable.

[0039] In the present embodiment, a bidirectional double-pressure wheel wire twisting device is also provided. In the device, the structure of the fixed pulley 220 is the same as that of the adjusting pulley 230, and the fixed pulley 220 can also be adjusted in position by the adjusting pulley 230, so that when the cable passes through the cable channel 300, the fixed pulley 220 and the adjusting pulley 230 are adjusted in position at the same time by the adjusting bolt 420, the cable can be squeezed and pushed as a whole to adjust the overall torque of the cable. At the same time, by precisely adjusting the position distance between the adjusting pulley 230 and the fixed pulley 220 through the adjusting bolt 420, the cable torque can be adjusted to a certain angle, and the cable with this torque angle can be twisted through the structure of the support plate 110 to form a required cable.

[0040] Specifically:

[0041] In the embodiment of the present application, since the support plate 110 is circular and 30 guide holes 111 are provided on the support plate 110, and guide wheel assemblies 200 are provided on both sides of the 30 guide holes 111, before the cables are wound, each cable passes through the guide wheel assemblies 200 and guide holes 111 at the corresponding positions. According to the different settings of the cables, the adjusting bolts 420 in the guide wheel assemblies 200 at the corresponding positions adjust the cable channels 300 accordingly, so as to facilitate the adjustment of the torque of each cable. At the same time, after the adjustment of the torque of the cables is completed, it is convenient to twist the multiple cables after the torque is adjusted as a whole, so as to facilitate the preparation of new cables.

[0042] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
