Tinned copper core polyperfluoroethylene propylene insulated wire and manufacturing device for aerospace

Abstract

The invention provides a tinned copper core polyperfluoroethylene propylene insulated wire for aerospace and a manufacturing device, the wire includes a copper core, a first insulating layer, a shielding layer, a second insulating layer, a protective layer and a balance layer; The outer surface of the copper core is tin-plated; the first insulating layer is extruded on the copper core; the shielding layer is covered on the outer surface of the first insulating layer; the second insulating layer is extruded and formed outside the shielding layer. The first insulating layer and the second insulating layer are polyperfluoroethylene propylene; the protective layer is arranged on the outer surface of the second insulating layer. The manufacturing device includes a segment positioning module, an electronic weighing module, an operation module, an execution module and a 3D printing module; it is used for segmenting, positioning and segment quality measurement of the wire after the protective layer is set; according to the quality of each segment and the setting Calculate the segmental standard quality to obtain the material consumption of the positioning segmental balance layer; form a control instruction; use the 3D printing module to control the material consumption of the printing positioning segmental balance layer.

AI Technical Summary

Problems solved by technology

[0004] Aerospace equipment has high requirements for balance, so the quality of each component needs to be considered in the design to evaluate or compensate for balance; wires exist in many parts of aerospace equipment, so wire quality evaluation will have an impact on the balance of aerospace equipment Therefore, if the linear distribution of the weight of the wire itself is not uniform, it will affect the balance of aerospace equipment, and the production of wires in the prior art does not pay special attention to the uniform linear distribution of the weight of the wire
