Description

Technical Field

[0001] This utility model relates to the field of cable production equipment technology, and in particular to a multi-core cable forming and guiding device. Background Technology

[0002] The problem of mixed conductor arrangement: Multi-core cables typically contain conductors with different functions (such as power transmission lines, signal lines, compensating wires, etc.), and their arrangement directly affects the cable's electrical performance and anti-interference capability. In the traditional multi-core conductor production process, each conductor is directly led from the material source or the corresponding conductor production equipment to the stranding equipment. Due to the large size of the material source or production equipment for each conductor, the lead-out distances and angles of each conductor vary significantly, easily leading to poor conductor positioning stability. Conductors are prone to shifting or twisting during cabling, resulting in a discrepancy between the actual arrangement and the design position, affecting the cable's impedance stability, signal transmission quality, and electromagnetic compatibility.

[0027] Reference Figures 1 to 3 The multi-core cable forming and guiding device of this utility model is illustrated in the following embodiments:

[0028] A multi-core cable forming and guiding device includes: a primary guiding component 10 and a secondary guiding component 20.

[0029] The primary guide assembly 10 has a central axis and primary guide holes 110. The central axis extends in the front-back direction, and there are multiple primary guide holes 110 arranged around the central axis.

[0030] The primary guide assembly 10 and the secondary guide assembly 20 are arranged one behind the other. The secondary guide assembly 20 has a plurality of secondary guide holes 310, and the distance between two adjacent secondary guide holes 310 is greater than the distance between two adjacent primary guide holes 110.

[0031] In practical use, multiple conductor wires pass through the secondary guide holes 310 and the primary guide holes 110 in sequence. The secondary guide holes 310, which are widely spaced and have a larger spacing, can provide initial guidance for the conductor wires, allowing them to initially converge within the range of the secondary guide assembly 20. Then, the primary guide holes 110, which are more closely spaced and have a smaller spacing, provide further guidance for the conductor wires, allowing them to converge within the range of the primary guide assembly 10. This achieves graded guidance for multiple conductor wires, enabling them to be stably led out to the forming station of the multi-core cable, avoiding deviation or twisting during forming, and improving the forming quality.

[0032] It is worth noting that there can be multiple multi-core cable forming guide devices, and multiple multi-core cable forming guide devices are arranged in sequence, with the secondary guide component 20 of the previous multi-core cable forming guide device serving as the primary guide component 10 of the next multi-core cable forming guide device, forming a multi-level guide structure.

[0033] In this embodiment, the multi-core cable forming and guiding device further includes a base 400, and the primary guiding component 10 and the secondary guiding component 20 are both disposed on the upper side of the base 400. At least one of the primary guiding component 10 and the secondary guiding component 20 is adjustablely connected to the base 400 in the front-back direction, so that the spacing between the primary guiding component 10 and the secondary guiding component 20 can be adjusted according to actual conditions, thereby improving adaptability.

[0034] The adjustable connection between the primary guide assembly 10 and the secondary guide assembly 20 and the base 400 can be achieved by existing adjustable connection methods, such as sliding connection through linear slide rails or slide groove structures, and detachable fixing or temporary positioning through bolt locking at different positions or pin structures; or it can be driven in the forward and backward directions by linear drive components such as cylinders, electric push rods, hydraulic push rods or lead screw and nut drive assemblies, which will not be described in detail in this application.

[0035] The primary guide assembly 10 of this embodiment includes a primary guide seat 100, which is mounted on the upper side of the base 400. Each primary guide hole 110 extends through the primary guide seat 100 in the front-to-back direction, and the front and rear ends of the primary guide hole 110 are respectively connected to the front and rear sides of the primary guide seat 100.

[0036] In practical use, the arrangement of the multiple primary guide holes 110 can be set according to the forming and arrangement requirements of each conductor wire of the multi-core cable. The primary guide seat 100 is detachably connected to the base 400. Multiple primary guide seats 100 are preset according to the conductor wire arrangement structure of different models of multi-core cables. When the specifications of the multi-core cables produced change, the corresponding primary guide seat 100 is replaced for adaptation, thereby improving applicability. Generally, in the projection in the front-back direction, the arrangement area of ​​the primary guide holes 110 is a circular range centered on the central axis.

[0037] Because of the large spacing between the secondary guide holes 310, at least a portion of the conductor wire extends at an angle between the primary guide assembly 10 and the secondary guide assembly 20. To avoid scratching the conductor wire, the end of the primary guide hole 110 facing the secondary guide assembly 20 has a flared arc shape that is narrower at the front and wider at the back.

[0038] The secondary guide assembly 20 includes a secondary guide seat 200, which in this embodiment is adjustablely connected to the base 400 in the front-rear direction. The secondary guide hole 310 passes through the secondary guide seat 200 to connect the front and rear sides of the secondary guide seat 200.

[0039] In some embodiments, the number of secondary guide holes 310 is the same as the number of primary guide holes 110, and the plurality of secondary guide holes 310 are arranged in a one-to-one correspondence with the primary guide holes 110. In this embodiment, the end of the secondary guide hole 310 near the primary guide component 10 is oriented toward the corresponding primary guide hole 110 to reduce wear on the conductor wire.

[0040] In this embodiment, to avoid the need to replace the secondary guide seat 200 when the specifications of the multi-core cable change, the number of secondary guide holes 310 of the secondary guide seat 200 is set according to the primary guide seat 100 with the most primary guide holes 110, so as to match more specifications of primary guide seats 100 and adapt to the production of multi-core cables of different specifications.

[0041] In this embodiment, to accommodate different introduction directions of each conductor wire, the secondary guide seat 200 is provided with a plurality of guide sleeves 300, each of the guide sleeves 300 being provided with a secondary guide hole 310, and the guide sleeve 300 being movably embedded in the secondary guide seat 200.

[0042] The guide sleeve 300 is spherical, and the secondary guide seat 200 is provided with multiple spherical receiving cavities. The arrangement of the multiple receiving cavities is set according to the arrangement requirements of the secondary guide holes 310. The guide sleeve 300 is movably embedded in the receiving cavity one by one.

[0043] The spherical guide sleeve 300 can rotate within the receiving cavity, and the orientation of the front and rear ends of the secondary guide hole 310 can be changed under the force of the conductor wire, thereby adapting to the guidance of conductor wires with different introduction and exit directions.

[0044] In this embodiment, the secondary guide seat 200 includes a front plate 210 and a rear plate 220, which are arranged one in front of the other. Each of the front plate 210 and the rear plate 220 has a receiving groove on its opposite side. The receiving groove is hemispherical in shape, and the receiving grooves of the front plate 210 and the rear plate 220 correspond one-to-one to form the receiving cavity.

[0045] As shown in the figure, the front plate 210 and the rear plate 220 have the same thickness, and the sum of their thicknesses does not exceed the diameter of the guide sleeve 300. To prevent the conductor wire in the secondary guide hole 310 from scraping and rubbing against the secondary guide seat 200 when the guide sleeve 300 deflects at a large angle, in this embodiment, the sum of the thicknesses of the front plate 210 and the rear plate 220 does not exceed the radius of the guide sleeve 300.

[0046] In a further embodiment, to accommodate situations where the distance between material sources or production equipment for each conductor wire is large, resulting in significant differences in the angle at which different conductor wires are introduced into the secondary guide assembly 20, the two ends of the secondary guide hole 310 are not aligned. Specifically, the secondary guide hole 310 includes a front hole section 311 and a rear hole section 312 that are interconnected, both of which extend radially along the guide sleeve 300. As shown in the figure, the front hole section 311 and the rear hole section 312 extend radially along the guide sleeve 300 in different directions, and are connected by an arc at the center of the guide sleeve 300.

[0047] The front section 311 and the rear section 312 of the secondary guide hole 310 are set at a certain angle, so that the front section 311 can be oriented as much as possible toward the corresponding primary guide hole 110, while the rear section 312 can be deflected at a larger angle relative to the front and rear directions, thereby adapting to the guiding requirements of conductor lines introduced at large angles.

[0048] Similarly, to prevent the guide sleeve 300 from scratching the conductor wire, both ends of the secondary guide hole 310 are flared arc transitions.
