Cable extrusion head

Abstract

The invention discloses a cable extruding machine head, which comprises a machine head body, the machine head body has a conical structure, an outer film group is arranged on the upper surface and the lower surface of the machine head body, and the outer film group consists of two adjacent outer film The outer membrane group is fixed on the machine head body, and a cylinder is connected between the outer membrane group and the machine head body on the lower surface of the machine head body, and the cylinder is fixed between the machine head body and the outer membrane group , and the lower surface of the outer membrane group located on the lower surface of the head body is provided with a cooling jacket, the cooling jacket covers the outer membrane group and the cylinder is set, the cooling jacket is made of tensile material, and the inner core is arranged horizontally in the head body , with at least two inner cores. The cable extruder head can realize multi-layer cable molding and extrusion at one time, and the cable can be processed according to actual needs, which can effectively meet the pressure demand of the liquid rubber material, making it less prone to clogging, and at the same time avoiding damage caused by repeated processing of the cable. The problem of low work efficiency, as well as the problem of surface damage caused by repeated cable processing.

Description

Technical field [0001] The invention relates to a die, in particular to a cable extrusion die. Background technique [0002] The extruder is a necessary equipment in the production process of wires and cables. With the advancement of engineering technology, the requirements for wires and cables in different project sites have also increased, such as waterproof, anti-static, etc., and the demand for wires and cables is large. Work efficiency should be further improved. In order to ensure the safety of wire and cable use, the outside of the cable is covered with an insulating layer. The insulating layer is generally a double-layer structure. Two extrusion methods are used to complete this structure. One is double-layer co-extrusion. Simple and high production efficiency, but because the two-layer insulation structure is cooled at the same time and the viscosity of some insulation materials is relatively large, it is easy to cause uneven thickness; the other is two extrusions, but ...

Problems solved by technology

In order to ensure the safe use of wires and cables, the outside of the cable is wrapped with an insulating layer. The insulating layer is generally a double-layer structure. Two extrusion methods are used to complete this structure. One is double-layer co-extrusion. Although the process of double-layer co-extrusion is Simple, high production efficiency, but because the two-layer insulation structure is cooled at the same time and some insulation materials are relatively viscous, it is easy to cause uneven thickness; the other is to extrude twice, but this process is more complicated and the production range is limited. , and such an extruder head cannot process cables better, resulting in low work efficiency
