A wire manufacturing process

Abstract

The invention relates to the field of wire manufacturing and discloses a wire manufacturing technology. The technology comprises the following steps: 1, conveying a stranded copper wire to a strandingmachine through a wire feeding frame for stranding; 2, conveying the copper wire harness to a mold through the wire feeding frame; 3, processing rubber particles through a screw extruder, wrapping the copper wire harness with the molten rubber particles to form an insulating layer, and cooling the insulating layer for forming by air cooling; 4, conveying the insulating layer and the copper wire harness to water, and reducing the surface temperature of the insulating layer through water cooling; 5, winding up the wire through a winding machine, wherein step 1 also comprises the substeps: continuous connecting the copper wire by a cold pressing process, and removing the excess copper wire after the continuous connection by sandpaper. The invention has the following advantages and effects that the technology utilizes a new mechanical structure; the continuous connection between the copper wires is not liable to affect the characteristics of the copper wires through the cold pressing process, so that the quality of the copper wire harness is enabled to be higher, thereby improving the quality of the produced wires.

Description

technical field [0001] The invention relates to the field of electric wire manufacturing, more specifically, it relates to a manufacturing process of electric wires. Background technique [0002] A wire is a wire that transmits electrical energy. The manufacturing process of electric wires is generally to twist the copper wires with smaller diameters first, and twist the copper wires with smaller diameters into a copper wire bundle with larger diameter, and then wrap the insulating layer on the outside of the copper wire bundles. At this time, the wires It has been made, and finally the wire is wound up, and the whole wire manufacturing process is completed. [0003] At present, in the manufacturing process of electric wires, since the length of each coil of copper wire is certain, it is necessary to continue the copper wire during the twisting process of the copper wire. Now the more common method is to connect the continuous copper wire Winding on the copper wire being t...

Problems solved by technology

[0003] At present, in the manufacturing process of electric wires, since the length of each coil of copper wire is certain, it is necessary to continue the copper wire during the twisting process of the copper wire. Now the more common method is to connect the continuous copper wire Winding on the copper wire being twisted, or heating the continuous copper wire and the copper wire being twisted to melt the two together, but after the copper wire is twisted, the thickness of the joint of the two copper wires Larger, causing the conductivity of the copper wire to change at the joint, and the way of melting changes the properties of the copper at the joint, which affects the conduction of the current, resulting in the quality of the manufactured wire not up to standard
