Description

Technical Field

[0001] The utility model relates to the technical field of wire harness accessories, in particular to a double guide roller component for wire harness processing. Background Art

[0002] The guide roller of wire harness processing is a tool used to guide and align the wire harness. It can ensure that the wire harness remains straight during processing and avoid bending or twisting of the wire harness, thereby improving the processing quality and efficiency of the wire harness. The guide roller is usually made of high-precision stainless steel material with a smooth surface and is not easy to wear. It can effectively protect the wire harness from being scratched or damaged. Its diameter and length can be customized according to the specific wire harness processing requirements to accommodate wire harnesses of different specifications and lengths. In the traditional wire harness processing process, a single guide roller or a simple guide mechanism is usually used to guide and fix the wire harness. These methods can often only guide the wire harness in a single direction and cannot achieve precise control of the wire harness in two directions, resulting in the wire harness being easily offset or derailed during processing, affecting the processing accuracy and quality.
