Alloy wire heat-conducting cable machining equipment

Abstract

The invention discloses alloy wire heat-conducting cable machining equipment. The alloy wire heat-conducting cable machining equipment comprises an insulation layer extrusion mold, an insulation extrusion heat-insulating cushion, an insulation layer cooling sleeve and a cable penetrating pipe which are sequentially arranged from the upstream part to the downstream part. The insulation layer cooling sleeve is provided with an insulation layer cooling cavity, an annular cooling water channel, a cooling water inlet and a cooling water outlet. The outer side of the cable penetrating pipe is sleeved with a wire-laying mounting plate. A linear guiding groove and an arc-shaped guiding groove are formed in the wire-laying mounting plate. Two wire-laying guiding pipes are arranged in the linear guiding groove and the arc-shaped guiding groove correspondingly, each wire-laying guiding pipe is connected with a guiding pipe mounting piece, and each guiding pipe mounting piece is connected with a guiding pipe driving air cylinder. The alloy wire heat-conducting cable machining equipment can rapidly cool an extrusion-wrapped insulation layer, and thus laying operation of heat-conducting wires can be conducted within the short time after extrusion wrapping of the insulation layer.

Description

technical field [0001] The invention relates to the technical field of heating cable processing equipment, in particular to an alloy wire heat-conducting cable processing equipment. Background technique [0002] The heating cable usually has a long length, so that it can be laid to cover a large area, or the pipeline that needs to be traced can be insulated and heated with a large length; however, due to the difference in ambient temperature at different locations, the When the heating power of the cable or the overall resistance value is constant, it is difficult to achieve the same or similar heat tracing temperature in different ambient temperatures; by laying thermal wires inside the heating cable to improve the thermal conductivity of the heating cable along the length direction, it can effectively to overcome the above deficiencies. [0003] However, conventional materials with good thermal conductivity are mostly metal or alloy conductors. The direct contact of metal...

AI Technical Summary

Problems solved by technology

[0002] The heating cable usually has a long length, so that it can be laid to cover a large area, or it can be used for heat preservation and heating of a large length of pipelines that need heat tracing; When the heating power of the cable or the overall resistance value is constant, it is difficult to achieve the same or close heating temperature in different ambient temperatures; by laying the heat conducting wire inside the heating cable, the thermal conductivity along the length direction of the heating cable can be improved, which can effectively to overcome the above deficiencies

[0003] However, conventional materials with good thermal conductivity are mostly metal or alloy conductors. Metal or alloy conductors directly contact alloy heating wires or PCT and other heating materials, which will cause a short circuit or cause the heating wire to be energized and burned. An insulating layer is extruded between the wire and the heating material, which leads to a more complicated processing technology for the heating cable containing the heat conducting wire. After the insulating layer is extruded, it takes a long time to completely cool and solidify the insulating layer before proceeding. The processing of laying the heat conduction wire makes the production line of the heating cable longer and occupies a larger space
