Description

Technical Field

[0001] The utility model relates to the technical field of automobile wire harness processing, in particular to a wire twisting device for automobile wire harness production. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. It refers to the contact terminal made of copper material, which is crimped with wires and cables, and then plastic-pressed with an insulator or an additional metal shell, etc., to form a component connecting the circuit with the wiring harness. The body wiring harness connects the entire body and is generally H-shaped.

[0003] When producing automotive wiring harnesses, the wire core needs to be twisted. However, the current twisting equipment fixes the two ends of the wire core and then twists the wire core, which causes the wire core to bend. The bending of the wire core will cause the straight length of the fixed ends of the wire core to be slightly smaller than the actual length of the wire core after bending, which in turn generates tension on the wire core. When the tension accumulates to a certain extent, it may cause the wire core to break. For this reason, we propose a twisting equipment for automotive wiring harness production to solve the above problem. Utility Model Content
