Description

A quick replacement device for cable cores

technical field

The invention belongs to the field of cable processing equipment, and in particular relates to a quick replacement equipment for cable cores.

Background technique

Cables are divided into single-core cables and multi-core cables according to different specifications. The cores are wrapped in the cable sheath. After the cable is used for a period of time, the cores will age. If the quality of the cable sheath is still good, You can use the method of replacing the core to extend the service life of the cable.

Because of the friction between the cable core and the cable sheath, it is very difficult to pull out and replace it, which often takes a lot of manpower time, especially for relatively long cables. It is more difficult to pull the core continuously, and during the pulling process Because of the asymmetrical axis of the tension, it is easy to cause permanent deformation of the core and cable sheath.

Therefore, in view of the situation that it is difficult to pull the wire core out of the above-mentioned cables, a new type of cable core pulling mechanism is developed, which uses a symmetrical self-propelled clamping mechanism to lock the cable sheath and the wire core respectively, so as to achieve a one-time pulling out of the wire core. Function of long cable cores.
