Description

Technical Field

[0001] The utility model relates to the technical field of wire harness production equipment, in particular to an automatic production device for a silicone wire harness. Background Art

[0002] Silicone wire, industrial name AGR silicone rubber wire, is made of silicone material, suitable for temperatures of -60℃~200℃, with excellent high and low temperature resistance, electrical insulation and chemical stability, etc. Wire harnesses are widely used in automobiles, household appliances, computers and communication equipment, etc. In the production and processing of wire harnesses, the wire harnesses need to be cut, stripped, crimped and finally packaged to complete the processing of the wire harnesses.

[0003] The existing silicone wire harnesses often have the following problems in the production process: the machine needs to be stopped when changing materials, which leads to a significant reduction in production efficiency during the material changing process. When the wire harnesses are cut manually, the cutting lengths are often uneven, and the wires need to be cut twice, which not only affects the production efficiency but also wastes raw materials and cannot meet people's usage needs. For this reason, we propose an automatic production device for silicone wire harnesses. Utility Model Content
