Description

Technical Field

[0001] The utility model belongs to the technical field of cable production, and specifically relates to a special-shaped conductor insulation extrusion tooling. Background Technique

[0002] Multi-core cables usually consist of multiple insulated wires, each wire is coated with an insulating layer, and other functional components such as shielding layers, filling materials, and outer sheaths are added as needed. The insulated wires can be arranged and combined differently according to different uses and installation environments to achieve specific electrical and physical properties. To ensure the roundness of the overall structure and reduce production costs, multi-core cables usually adopt special-shaped conductor structures, such as fan-shaped, tile-shaped, etc. These special-shaped conductors have a smaller core diameter after stranding compared to traditional round conductors, and the core after stranding is more round, which can reduce or even eliminate the need for filling materials, thus significantly reducing material costs.

[0003] In the production process of the special-shaped conductor structure, the conductor is first processed into a special-shaped structure such as a fan shape or a tile shape, and then the insulating layer is extruded and coated. Due to the specific shape of the insulated wire core of the special-shaped conductor structure, the core structure after stranding is more compact and uniform. During the insulating layer extrusion process, special extrusion dies are usually used to ensure that the insulating material can evenly cover the surface of the conductor. This not only improves production efficiency but also effectively controls the usage amount of materials, thereby reducing production costs.

[0004] Although the special-shaped conductor structure has significant advantages in the production of multi-core cables, there are also certain defects. First, the special-shaped conductor structure is prone to uneven insulation thickness during the insulation extrusion process, especially at the thinnest point of the conductor, where it is often difficult for the insulating layer to meet the standard requirements. If this problem is solved by thickening the insulating layer, it will lead to an increase in the cost of insulating materials. Second, when using a round conductor extrusion die for production, the fan-shaped conductor is prone to deflecting to one side, causing the conductor to rub against the die and resulting in a thinner thickness on one side of the insulating layer. This not only affects product quality but may also increase the wear of production equipment. Content of the Utility Model

[0005] The purpose of the utility model is to provide a special-shaped conductor insulation extrusion tooling to solve the problems raised in the above-mentioned prior art.

[0030] Please refer to Figures 1-9 As shown, in the embodiment of the present utility model, a special-shaped conductor insulation extrusion tooling includes a lifting assembly 1. The upper and lower sides of an adjustment frame 2 are slidably connected with adjustment pressure wheels 3. A special-shaped conductor 4 is clamped between the two adjustment pressure wheels 3. The adjustment frame 2 is arranged on the lifting assembly 1. The lifting assembly 1 is fixed to the ground by expansion bolts to ensure the stability of the overall equipment. The adjustment frame 2 adapts to different production requirements by adjusting the height. The adjustment pressure wheels 3 connected by up and down sliding clamp the special-shaped conductor 4 to maintain the stability and uniformity of the conductor. One side of the upper part of the adjustment frame 2 is provided with an extrusion die core 5. The extrusion die core 5 is sleeved on the special-shaped conductor 4. An extrusion die sleeve 6 is arranged on the extrusion die core 5. The extrusion die core 5 is provided with an outlet opening 51. The designs of the extrusion die core 5 and the extrusion die sleeve 6 are consistent with the outer dimensions of the special-shaped conductor 4, ensuring that the outer dimensions of the outlet opening 51 are enlarged equidistantly, guaranteeing the consistency of the thickness of the extruded insulating layer. By using the special-shaped extrusion die core 5 and the extrusion die sleeve 6, the insulating material can be extruded according to the special-shaped flow channel between the extrusion die core 5 and the extrusion die sleeve 6, so as to achieve the same thickness of the insulating layer on the surface of the special-shaped conductor 4 and avoid the problem of eccentricity. Due to the particularity of the special-shaped conductor 4 itself, its outer surface is quite different from that of a circular conductor, and it has multiple special-shaped surfaces such as arc surfaces and inclined surfaces. Therefore, a special extrusion die core 5 and an extrusion die sleeve 6 are set to be consistent with the outer surface of the special-shaped conductor 4 to ensure the uniform thickness of its insulating layer, thereby reducing the insulating material and achieving cost reduction and efficiency improvement;

[0031] A cooling water tank 7 is also arranged on one side of the extrusion die core 5. A wire stabilizing assembly 8 is arranged in the cooling water tank 7. The special-shaped conductor 4 is clamped in the wire stabilizing assembly 8 on the side far from the extrusion die core 5. The wire stabilizing assembly 8 is arranged in the cooling water tank 7 to ensure the stable cooling of the special-shaped conductor 4 on the side far from the extrusion die core 5. The design and position adjustment of the wire stabilizing assembly 8 ensure the stability of the conductor during the cooling process, avoiding skew and uneven cooling. The tube extrusion process ensures that the insulating material is evenly covered on the surface of the special-shaped conductor 4, avoiding the appearance of weak points and improving the insulation quality;

[0032] By adjusting the vertical positions of two adjusting pressure wheels 3 within the adjusting frame 2, the limited-profile conductor 4 moves during the insulation extrusion process, enabling the profile conductor 4 to remain stable during extrusion, ensuring the consistency of the insulation thickness, avoiding weak points. In addition, the adjusting frame 2 and the wire-stabilizing assembly 8 are respectively located in front of and behind the extrusion die core 5, ensuring that the profile conductor 4 is always on the same horizontal line during the insulation extrusion process, reducing skewing and rubbing phenomena during production. Moreover, the precise cooperation between the extrusion die core 5 and the extrusion die sleeve 6 and the application of the tube extrusion process improve production efficiency, ensure the smoothness and stability of the extruded insulation layer, thereby enhancing product quality. Due to the consistency of the produced insulation thickness and the reduced demand for filling materials, the problem of uneven insulation thickness during the insulation extrusion of the profile conductor 4 structure can be effectively solved. In addition, it can ensure that the profile conductor 4 is always on the same horizontal line during production, reducing the occurrence of skewing and rubbing phenomena during the production of the profile conductor 4.

By rotating the lifting screw nut 14, the lifting screw rod 13 moves up and down within the lifting screw nut 14, thereby realizing the up and down movement of the lifting screw rod 13 and driving the height adjustment of the adjusting frame 2 fixedly connected to its top, thus realizing the height control of the adjusting frame 2.

The first U-shaped groove 21 allows the flexible movement of the adjusting pressure wheels 3, enabling the device to adjust the positions of the adjusting pressure wheels 3 according to different production requirements to adapt to the production of conductors of different specifications.

[0035] Furthermore, in one embodiment, please refer to Figure 1 、 Figure 4 、 Figure 6 and Figure 8As shown, the wire outlet opening 51 is fan-shaped and is used for the insulation extrusion of the special-shaped conductor 4 with a fan shape.
