Description

Technical Field

[0001] The utility model belongs to the technical field of electric wire and cable production equipment, in particular to a production device for reducing the eccentricity of electric wire and cable. Background Art

[0002] The insulation layer on the outside of the core of wires and cables is mainly made of polymer rubber and plastic materials. The insulation layer is a key process in the production of wires and cables, and is mainly produced by cable extrusion equipment. The equipment consists of a fuselage, a head, a mold and a traction system. The traction system passes the conductor through the head from the core mouth of the mold. After the polymer material is heated in the fuselage, it is extruded into a cylindrical shape through the cavity of the head and the mold.

[0003] The conductors commonly used in the core of wires and cables are hard conductors and soft conductors. Cables with soft conductors can be bent frequently during use and are convenient for transportation and installation. The outer diameter and shape of the hard conductor structure are stable. When the insulating material is extruded and matched with the mold, the mold core of the insulating layer can be slightly larger than the outer diameter of the conductor; while the outer diameter and shape of the soft conductor structure are unstable. The conductor is easily deformed to varying degrees when it is squeezed during the winding tooling reel and the extrusion and wire drawing process.

[0004] Therefore, when producing cables with soft conductors, the size of the insulation layer die core selected on the extrusion equipment needs to refer to the maximum outer diameter of the soft conductor after deformation, so that the insulation layer can be smoothly sheathed on the outside of the soft conductor. However, when the local die spacing of the soft conductor is large, when the extrusion equipment extrude the insulation layer, the non-round soft conductor will vibrate when passing through the die core, resulting in a large deviation in concentricity, and the insulation layer extruded on the conductor will be eccentric with one side thicker and the other side thinner.

[0005] The Chinese utility model patent with application number CN201820722840.2 discloses a shaping and positioning device and extrusion equipment for reducing the eccentricity of the cable insulation layer, which relates to the field of wire and cable production equipment. It includes a positioning through hole that can allow the cable core to pass through. The positioning through hole is a through through hole, and also includes a fixing seat and a connecting seat that are fixedly connected to each other. A positioning adjuster is provided on the connecting seat, and an adjustment device and multiple shaping devices are provided on the positioning adjuster. The shaping device includes a shaping pressure wheel arranged along the circumference of the positioning through hole, and an arc groove is provided on the circumference of the shaping pressure wheel. The adjustment device is used to drive the shaping pressure wheel to approach or move away from the positioning through hole. This device is used to position the cable core and correct the deformed cable core to solve the problem of large eccentricity of the insulation layer caused by core deformation, save costs, and improve the yield rate.

[0006] However, the positioning device in this patent is large in size and inconvenient to connect to the extruder when in use. At the same time, since the shaping positioning device itself has a base, the shaping positioning device cannot ensure parallelism with the extrusion port plane of the extruder, thereby affecting the shaping effect of the shaping roller on the cable.
