Embodiment Construction
[0008] The present invention will be described in detail below in conjunction with specific embodiments.
[0009] The present invention is illustrated by using a stranded conductor with a diameter of 0.20 mm, 1596 copper wires, and a conductor cross-sectional area of 50 mm2.
[0010] First place the 1596 copper wires on the 3000-head vertical pay-off rack, and distribute the 1596 equally with the base of 3; then pass every 3 copper wires into the hole of the branching board; then from the branching board The copper wire passing through the hole is again evenly distributed into 19 strands, penetrated into the alloy die hole and then twisted by a high-speed copper twisting machine, and finally the wire is taken up by a twisted copper wire take-up machine to complete one-time twisting. The stranded outer diameter is 9.50 mm.
[0011] Traditional stranding process: using a three-step stranding process with a diameter of 0.20mm, 1596 copper wires, and a conductor cross-sectional area o...

Abstract
The invention discloses conductor processing process improvement for a new energy electric automobile. The improvement comprises the following technical process: first of all, placing a multiaxial copper wire on a vertical type pay-off rack, and evenly distributing the total number of axles of the copper wire; then respectively penetrating the copper wire after even distribution into holes of a distributor plate; then re-distributing the copper wire penetrating the holes of the distributor plate evenly into multiple strands, passing through alloy mold holes, then going into a high-speed copper wire twisting machine for twisting, and finally performing wire collection through a copper wire twisting collection machine so that a twisting process is completed at a time. According to the invention, through successive use of such a processing process of the vertical pay-off rack, the distributor plate, the alloy mold holes, the high-speed copper wire twisting machine and the like, multiple stands of conductors can be twisted at a time, and the twisting process is simple; the conductor twisting time is shortened, and the work efficiency is improved; the equipment electricity consumption is reduced and energy is saved; the labor input is reduced and the production cost is decreased; and for the same sectional area, the external diameters of twisted conductors are obviously reduced, the insulation material for a wire is reduced, the cost of the whole wire is lower, and the competitive edge at a client is high.
Description
Technical field [0001] The invention belongs to the technical field of wires and cables, and relates to conductor processing technology, in particular to the improvement of conductor processing technology for new energy electric vehicles. Background technique [0002] Traditional multi-strand conductors are generally completed by three-stranding method, such as 19-strand conductors. First, a pay-off machine and a 500-type copper stranding machine are used for the first time to twist multiple copper wires into a single strand. 7 single strands are twisted, the third time the twisted 7 single strands plus 12 single strands are twisted using a tube stranding machine. Although the stranding process is finally completed, the stranding process is complicated and can be completed after three times. It takes a long time and the stranding outer diameter is large. It is difficult for customers to penetrate the terminal hole when processing the end. [0003] When the conductor cross-sectiona...
