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, 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 reserved wire length at both ends of the cable with PE film to fix it, and place it i...

Embodiment 2

[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, then cut the length of the cable according to the cutting formula, and reserve a certain length at both ends;

[0051]S3. Rolling: Manually roll the cut wire into a coil, and wrap the end of the reserved wire length at both ends of the cable with PE film to fix it, and pl...

[0061] Specifically include the following steps:

[0062] 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;

[0063] 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, 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 new energy automobile8-shaped telescopic easy-to-store charging wire manufacturing process, which comprises the steps: S4, baking: installing two cylindrical dies which are vertically or horizontally fixed and placed (one end is fixed and the other end is open) and are the same in outer diameter and length in an oven, starting to wind from the inside to the outside alongan S-shaped route at the open end of each die to wind an elastic charging wire into an 8-shaped wire harness, fixing the two ends of the wire, and baking the wire until an 8-shaped charging wire is formed. The invention relates to the technical field of charging wires. According to the manufacturing process of the 8-shaped telescopic easy-to-store charging wire for the new energy automobile, through a baked 8-shaped cable, storage is easy, operation is easy, deformation and loosening cannot be caused during storage and placement, and the 8-shaped telescopic easy-to-store charging wire can be directly hung after storage, so that the problems that a traditional linear charging wire is inconvenient to store and inconvenient to use are solved, and the risk of twisting and bulging of the charging wire after frequent use due to non-standard storage is also reduced.

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...
