Description

Technical Field

[0001] The invention relates to a wire twisting device, and in particular to a rotary wire twisting device and method. Background Art

[0002] At present, in automotive electronic circuits, sensors such as engine crankshafts, radios and retractors, ABS systems, CAN lines and other modular systems all require twisted pair cables. With the rapid development of automotive electronics, modular devices and CAN lines are increasingly widely used, and twisted pair circuits are becoming more and more common. Twisted pair cables are generally made up of two wires twisted together at a certain pitch, and have a certain anti-interference effect. Twisted pair cables can improve the flexibility of wires and reduce the risk of wire breakage. At the same time, the cable structure of twisted double wires can improve the wear resistance and corrosion resistance of wires, thereby extending the service life of wires.

[0003] In the prior art, in order to improve the production efficiency of twisted pair cables and ensure the quality of twisted pair cables, the twisting method has evolved from traditional manual twisting to semi-automatic twisting machines and then to automatic twisting machines. Even so, there are still many problems with automatic twisting machines: first, the twisting speed of automatic twisting machines is generally 2000 rpm-3000 rpm, and the working efficiency is low; second, the existing automatic twisting machines are not stable enough during operation and the wires are prone to being thrown out due to centrifugal force when rotating the twisted wires, which in turn affects the twisting quality of the wires; third, the two wires are entangled with each other when twisted, and the length of the finished twisted pair cable will be shorter than the original wire. However, since the existing equipment lacks the function of wire length compensation, the twisted pair cable is passively stretched, which may cause internal damage to the wire.
