Technical Field

[0001] The utility model relates to the technical field of electric wire and cable production, in particular to a wire twisting device for producing electric wire and cable. Background Art

[0002] Wires and cables are widely used in all walks of life. For example, household electrical appliances need to be powered by wires. Usually, wires are composed of two parts. The plastic insulated sheath wraps the copper or aluminum core inside, and the outer sheath is to prevent the inner core from mechanical damage. Wires and cables are made through three processes: drawing, twisting, and coating. The more complex the model specifications, the higher the repeatability. Twisting is to obtain different numbers of cores so that the cores can be used in different places.
