Description

Technical Field

[0001] The utility model relates to the technical field of wire harness processing, in particular to a wire harness baking and softening device. Background Art

[0002] The wiring harness is a whole of service equipment for a certain load source group, such as relay lines, switching devices, control systems, etc. The wiring harness is mostly composed of several transmission lines of different colors and wrapped with rubber sleeves. During the production process of the wiring harness, it needs to be shaped or wound into a wiring harness roll for subsequent processing and use. Since the rubber sleeve will soften in a high temperature environment for easy processing, and when the temperature of the processing site is low in winter, the wiring harness will become stiff, making it inconvenient for subsequent processing.
