Description

Technical Field

[0001] This utility model relates to the field of cable production equipment, specifically to a conductor stranding and diameter reduction guide mold. Background Technology

[0002] During cable production, multiple conductor wires are twisted into a bundle to ensure the stability and strength of the cable conductor. However, if the conductor wires are unevenly distributed before twisting, the bundled conductor wires will also be unevenly distributed after twisting, resulting in poor conductor quality and problems such as low power transmission efficiency and high-voltage breakdown during use. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a conductor stranding and diameter reduction guide mold that ensures the forming quality of conductor wires stranded into bundles.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: a conductor stranding diameter reduction guiding mold, including a guiding cylinder and a sleeve, the sleeve being sleeved on the outside of the guiding cylinder, the outside of the guiding cylinder being conical, and the outside of the guiding cylinder being provided with multiple guiding grooves along the conical surface of the guiding cylinder, the multiple guiding grooves being evenly distributed along the circumference of the guiding cylinder, the guiding grooves being used to guide the conductor wire to reduce its diameter, and the inside of the sleeve fitting with the top of the guiding groove.

[0005] Compared with the prior art, the advantages of this utility model are as follows: Through the design of the reduced diameter of the guide cylinder and the design of the guide groove, the conductor wires to be twisted are sequentially passed through the guide groove, avoiding interference between the conductor wires before twisting, preventing mutual compression before twisting, and thus preventing misalignment of the conductor wires during twisting. The uniform distribution of the guide grooves ensures the uniformity of the conductor wire twisting after the conductor wires pass through the guide grooves, thereby guaranteeing the twisting quality. Because the conductor wire twisting process is dynamic, there is a possibility that the conductor wire may detach from the guide groove due to equipment vibration, or even jump directly into another guide groove. The sleeve design ensures the stability of the conductor wire's movement within the guide groove, preventing detachment. Furthermore, the outer structure of the guide cylinder is toothed; if workers accidentally approach during the twisting process, it could easily cause injury. The sleeve design reduces the potential danger posed by the guide cylinder.

[0006] As an improvement of this utility model, both ends of the guide groove are provided with chamfers. This improvement prevents the conductor wire from being damaged when entering and leaving the guide groove.

[0007] As an improvement of this utility model, the guide cylinder and the sleeve are fixedly connected by fasteners. The guide cylinder is provided with a plurality of threaded holes for fixing with fasteners, and the sleeve is provided with a plurality of through holes for fixing with fasteners. Through this improvement, the fixed connection between the guide cylinder and the sleeve is achieved.

[0008] As an improvement of this utility model, the threaded hole is provided on the side wall of the guide groove. Through this improvement, the smoothness of the internal structure of the guide groove is ensured, so as not to damage the conductor wire, and the fixed connection between the guide cylinder and the sleeve is also ensured.

[0009] As an improvement of this utility model, the through hole is a countersunk through hole. This improvement avoids the fastener protruding from the sleeve and ensures the appearance quality of the sleeve.

[0010] As an improvement of this utility model, both the guide tube and the sleeve are made of high-strength nylon. Through this improvement, compared with metal materials, high-strength nylon materials are lower in cost and easier to process, and can be processed according to the conductor requirements.

[0011] As an improvement of this utility model, each end of the sleeve is provided with a reinforcing and shaping groove. The reinforcing and shaping groove is used to install a clamp to enhance the connection stability between the sleeve and the guide cylinder. The through hole is provided in the reinforcing and shaping groove. Through this improvement, the clamp enhances the tight fit between the sleeve and the guide cylinder. The design of the reinforcing and shaping groove can prevent the clamp from moving during the fixing process and ensure the stability of the clamp in use. At the same time, the clamp also strengthens the fixed connection between the guide cylinder and the sleeve.

[0012] As an improvement of this utility model, a central hole is provided on the axis of the guide cylinder. The central hole is used to position the guide cylinder. Through this improvement, during the conductor wire stranding process, the stranded conductors need to be bundled on the axis of the guide cylinder, which can better ensure the uniformity of conductor wire stranding. Therefore, during the stranding process, it is necessary to ensure that the guide cylinder rotates along the axis. The design of the central hole allows the guide cylinder to be better rotated, connected, and positioned. During the driving of the guide cylinder to rotate, it is ensured that the rotation axis of the guide cylinder coincides with the axis of the guide cylinder.

[0013] As an improvement of this utility model, one end of the central hole is a straight hole for positioning, and the other end of the central hole is a tapered hole with a reduced diameter. The tapered hole has the same slope as the outer side of the guide cylinder. Through this improvement, the design of the straight hole facilitates positioning, and the design of the tapered hole is used to ensure the structural strength of the guide cylinder and avoid deformation.

[0014] As an improvement of this utility model, a fixed connection hole is provided on the end face of one end of the central hole, which is used to fix the guide cylinder to an external device. Attached Figure Description

[0020] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0021] like Figure 1-3 As shown, a conductor stranding diameter reduction guiding mold includes a guiding cylinder 1 and a sleeve 2. The sleeve 2 is sleeved on the outside of the guiding cylinder 1. The outside of the guiding cylinder 1 is conical, and the outside of the guiding cylinder 1 is provided with multiple guiding grooves 1.1 arranged along the conical surface of the guiding cylinder 1. The multiple guiding grooves 1.1 are evenly distributed along the circumference of the guiding cylinder 1. The guiding grooves 1.1 are used to guide the conductor wire to reduce its diameter. The inside of the sleeve 2 fits with the top of the guiding groove 1.1.

[0022] Both ends of the guide groove 1.1 are provided with chamfers 1.2.

[0023] The guide cylinder 1 and sleeve 2 are fixedly connected by countersunk bolts 3. The guide cylinder 1 has four threaded holes 1.4 for fixing with the countersunk bolts 3. The threaded holes 1.4 are located on the side wall of the guide groove 1.1. The sleeve 2 has four countersunk through holes 4 for fixing with the countersunk bolts 3. During the fixing process, the alignment between the threaded holes 1.4 and the countersunk through holes 4 can be adjusted by rotating the sleeve 2 to ensure the fixed connection between the sleeve 2 and the guide cylinder 1. During the processing, more threaded holes 1.4 can also be machined on the guide cylinder 1, for example, eight threaded holes 1.4 can be machined on the guide cylinder 1. Then, during the rotation of the sleeve 2, only four of the threaded holes 1.4 need to be aligned with the countersunk through holes 4 to achieve the fixed connection between the sleeve 2 and the guide cylinder 1.

[0024] Both the guide cylinder 1 and the sleeve 2 are made of high-strength nylon. Each end of the sleeve 2 has a reinforcing groove 2.1, which is used to install a clamp to enhance the connection stability between the sleeve 2 and the guide cylinder 1. The countersunk through hole 4 is located within the reinforcing groove 2.1. The clamp is a conventional connector, fixed by compression through a diameter reduction method.

[0025] like Figure 1-4 As shown, a central hole 1.3 is provided on the axis of the guide cylinder 1. The central hole 1.3 is used to position the guide cylinder 1. One end of the central hole 1.3 is a straight hole 1.3.1 for positioning, and the other end of the central hole 1.3 is a tapered hole 1.3.2 with a reduced diameter. The tapered hole 1.3.2 has the same slope as the outer side of the guide cylinder 1. A fixed connection hole 1.5 is provided on the end face of one end of the central hole 1.3. The design of the fixed connection hole 1.5 realizes the fixed connection between the guide cylinder 1 and the external device, and the design of the central hole 1.3 realizes the coaxial fixed connection between the guide cylinder 1 and the external device, thereby ensuring the stranding quality when the conductor wires are stranded into bundles.

[0026] By designing a conductor stranding and diameter reduction guide mold, multiple conductor wires that need to be stranded into a bundle are guided to ensure that there is no interference between the multiple conductor wires during stranding and to ensure the uniform distribution of the conductor wires during stranding. This ensures the quality of the conductor wire strands being stranded into a bundle and avoids problems such as low transmission efficiency and high voltage breakdown in the subsequent use of the cable.
