Abstract
The invention relates to a copper-clad steel stranded wire and a production process thereof. The production process is characterized by adopting low-carbon steel (SWRH22A steel) as a main production raw material and comprising the steps of surface treatment, drawing, normalizing heat treatment, copper plating, drawing and stranding to obtain the finished-product copper-clad steel stranded wire. The copper-clad steel stranded wire is low in energy consumption, mould loss and broken wire ratio and high in labor production rate. The copper-clad steel stranded wire has the advantages that the requirements on the signal transmission of the copper stranded wire are met, nonferrous metals are saved, and the snap-resisting force is improved.
Description
Technical field
The present invention relates to a kind of copper covered steel twisted wire and production technology thereof, be mainly used on the military insulate line.
Background technology
Military insulate line originally had two injection moulding lead pair twists to form, and was mainly used in army's communication, transmitted signal.Begin lead that military insulate line uses three zinc-coated wires and four copper wires totally seven stranded forming are arranged; Three zinc-coated wires twist together as heart yearn and play the effect that improves the lead pull-off force, and four copper cash are stranded in the galvanized steel wicking surface and play the signal effect that transmits.This product has two bigger defectives: 1, in the production process because of the copper wire pulling force less stranded in easy fracture of wire, the scale rate is lower, causes the lead brachycephaly more.2, because of former lead the inside is that the steel core outside is a copper cash, signal corps is in route wires, and connecting two leads must connect respectively after separately lead is about, has not only wasted the time but also improved working strength, extremely inconvenience.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency; A kind of copper covered steel twisted wire and production technology thereof are provided; This copper covered steel twisted wire is practiced thrift non-ferrous metal greatly, has made things convenient for signal corps to lay, and production technology optimization, energy consumption, mould consume simultaneously, wire broken rate is low, labor productivity is high.
