Abstract

The invention relates to the machining field, and in particular relates to a production device for cable protecting casings with external spiral lines. The production device for the cable protecting casings with the external spiral lines is mainly formed by combing a perfusion connector and a forming cover die, wherein the perfusion connector is connected with a forming cover die, and the forming cover die comprises an external fixed cover die and an internal fixed cover die. According to the production device for the cable protecting casings with the external spiral lines, an HDPE (high density polyethylene) melting tube blank is extruded from a die, enters a space between the external fixed cover die which rotates and sprays water for cooling and an internal fixed cover die which is communicated with cooling water, and is pulled by a traction machine, so that a protecting casing with an external spiral line is formed, the external spiral line and a tube body are formed at the same time and tightly combined together, the external spiral line is prevented from falling off, an inner wall is formed by the internal fixed cover die, the smooth and flat inner wall is ensured, the inner wall corresponding to the external spiral line is free of dents, and the uniform thickness of the tube body is ensured.

Description

【Technical field】 [0001] The invention relates to the field of mechanical processing, in particular to a production device for an outer spiral cable sheath tube. 【Background technique】 [0002] The traditional outer spiral cable sheathing pipe production device has a forming sleeve mold with an integral structure. Cooling water cannot be filled in the forming sleeve mold. The forming of the helix also needs to carve spiral gaps in the sleeve mold, and the forming effect is poor. There are dents on the inner wall corresponding to the outer helix, which can easily lead to inconsistent wall thickness. 【Content of invention】 [0003] The purpose of the present invention is to provide a production device for the outer helical cable sheath tube, which aims to solve the problems of inconsistent wall thickness and dents on the inner wall of the helical cable sheath. [0004] The present invention is achieved in this way, a production device for outer helical cable sheathing tube,...
