Problems solved by technology

[0003] The problem of the cables in the prior art is that the extruder head connection mechanism is complicated, the cost is high, and the insulation layer wrapped by the cable is not tightly wrapped, and gaps are prone to appear. The reason is that the cooling is not enough when cooling. lead evenly

Abstract

The invention relates to a cable extrusion head simple in structure. The cable extrusion head simple in structure comprises a die sleeve, a die core, a cooling machine, a cable core seat, a cold air duct and an annular cutter, wherein the die core is arranged inside the die sleeve, a die core inner hole is contained in the interior of the die core, the die sleeve is composed of two reducing concentric cylinder sections, and the outer diameter of the rear section is smaller than that of the front section; a screw thread is formed at the periphery of the rear section; a connecting groove is formed in the die core, the rear end of the die sleeve is fixedly connected with the connecting groove by virtue of a screw thread; and a bolt is arranged on the side wall of the cable core seat, and thebolt is fixedly connected with the die sleeve. The cable extrusion head provided by the invention is simple in structure, is a common structure and is low in manufacturing cost, and the arranged cooling machine can uniformly pre-cool when a cable insulation layer is wrapped by virtue of the annularly distributed condensation branch pipe, so that a cable and the insulation layer are tightly wrapped, and a gap caused by non-uniform cooling can not be formed.

Description

technical field [0001] The invention relates to a cable extrusion machine head with simple structure. Background technique [0002] 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 engineering sites have also increased, such as waterproof, anti-static, etc., and the demand for wires and cables is large. It is required that work efficiency should be further improved. [0003] The problem of the cables in the prior art is that the extruder head connection mechanism is complicated, the cost is high, and the insulation layer wrapped by the cable is not tightly wrapped, and gaps are prone to appear. The reason is that the cooling is not enough when cooling. lead evenly. Contents of the invention [0004] In order to solve the above-mentioned problems in the prior art, the present invention provides a cable extruder head with a simple structure, wh...
