Embodiment 1

[0035] Specifically include the following steps:

[0036] S1. Preparation: After the linear extrusion is completed, use glass fiber or nylon wire to weave, then apply silicone oil, and dry at low temperature. After waiting for cooling, place the entire axis of cable on the lifting frame of the wire cutting machine and fix it. Raise to the highest point, then pass the first end of the cable through the fixed pulleys and extend to the cutter of the wire cutting machine;

[0037] S2. Strip cutting: set the parameters of the wire cutting machine according to the production drawings, and the skin must not be scratched. The calculation formula for strip cutting is: L=2(L1+L2), where L1=5πd, L2=2*L1= 10πd, where L is the length of the cable used, d is the outer diameter of the cable, then cut the length of the cable according to the cutting formula, and reserve a certain length at both ends;

[0038] S3. Rolling: Manually roll the cut wire into a coil, and wrap the end of the reserv...

[0048] Specifically include the following steps:

[0049] S1. Preparation work: After the linear extrusion is completed, weave it with glass fiber or nylon wire, then apply silicone oil, and dry it at low temperature. After cooling down, place the entire axis cable on the lifting frame of the wire cutting machine and fix it. And lift to the highest point, then pass the first end of the cable through the fixed pulley in turn and extend to the cutter of the wire cutting machine;

[0050]S2. Strip cutting: set the parameters of the wire cutting machine according to the production drawings, and the skin must not be scratched. The calculation formula for strip cutting is: L=2(L1+L2), where L1=5πd, L2=2*L1= 10πd, where L is the length of the cable used, d is the outer diameter of the cable, then cut the length of the cable according to the cutting formula, and reserve a certain length at both ends;

Abstract

The invention discloses a manufacturing process of an 8-shaped retractable and easy-to-accommodate charging cable for new energy vehicles. S4. Baking: in the oven, install vertically or horizontally (one end is fixed and the other end is open) with two outer diameters and lengths The same cylindrical mold, start winding along the "S"-shaped route from the inside to the outside at the open end of the mold, wind the elastic charging wire into an "8"-shaped harness, fix the two ends of the wire, and start to bake the wire , until an "8"-shaped charging line is formed; the present invention relates to the technical field of charging lines. This 8-shaped retractable and easy-to-storage charging cable for new energy vehicles is made by baking the "8"-shaped cable. The storage is simple and easy to operate, and storage and placement will not cause deformation and looseness. It can be hung directly after storage, which solves the inconvenient storage of the traditional linear charging cable, and also reduces the risk of the charging cable twisting and bulging after frequent use due to irregular storage.

Description

technical field [0001] The invention relates to the technical field of charging wires, in particular to a manufacturing process of an 8-shaped retractable and easy-to-storage charging wire for new energy vehicles. Background technique [0002] For the existing spring-type charging cables in the market, the size of the spring part is limited by the oven and the oven mold. Different sizes of spring coils need to use different sizes of wire molds. The molds are not universal and the processing cost is high. The same The length of use, the wire required by the spring type wire is twice that of the straight type, and the cost is high. During the use of the spring wire, the wire and the connection between the two ends of the wire will be subjected to a large axial pulling force, and it will be used for a long time. In the end, the axial elasticity of the spring wire will be insufficient, the deformation will be loose, and there will be a risk of wire breakage at the same time. The...
