Extrusion device on power cord preparation equipment

Abstract

The invention provides an extrusion device of power line manufacturing equipment, and belongs to the technical field of wires and cables. By adoption of the extrusion device of the power line manufacturing equipment, the technical problem of non-uniform thickness of an insulation layer is solved. The power line manufacturing equipment comprises a main shaft. The extrusion device comprises a second base and a steel pipe fixedly connected with the second base. A second support is further fixedly arranged on the second base. Three extruding machines are evenly arranged on the second support. Each extruding machine comprises a machine shell, an extruding screw and a feeding pipe, wherein the machine shell is tubular, and an extruding nozzle is arranged at one end of the machine shell; a feeding rod perpendicular to the machine shell is arranged on the machine shell, and the feeding rod is of a hollow structure; the extruding screw is inserted into the extruding rod, and the feeding pipe communicates with a cavity of the extruding rod; and an impeller is fixedly arranged at the upper end of the extruding screw and located in the steel pipe. The two ends of the steel pipe are connected with an oil pump through hoses correspondingly, and hydraulic oil is injected into the steel pipe. The extrusion device of the power line manufacturing equipment has the advantage that thickness distribution of an insulation layer is uniform.

Description

Technical field [0001] The invention belongs to the technical field of wires and cables, and relates to an extrusion device on a power cord preparation equipment. Background technique [0002] The power cord consists of phase, neutral and ground wires after being armored or plastic wrapped, and then wrapped by an outer sheath to form a finished product. At present, the production process is complicated and involves a lot of equipment, and they are all separately After the phase wire, neutral wire and ground wire are produced, they are prepared by wrapping the outer sheath. The construction period is long, the wire is coiled many times, and the damage and pollution to the wire are large. It cannot be completed at one time. The overall quality and performance of the line have a negative impact. Summary of the invention [0003] The purpose of the present invention is to provide an extrusion device on a power cord preparation equipment in view of the above-mentioned problems in the ...
