Cable wire drawing structure and cable wire drawing method

Abstract

The invention relates to the technical field of cable processing, and specifically relates to a cable wire drawing structure. The cable wire drawing structure comprises a wire drawing box, wherein a pay-off assembly and a wire drawing assembly are arranged on the wire drawing box; the wire feeding assembly comprises a pay-off wheel and a one-way wire-fixing device; the pay-off wheel is arranged atthe head end of the wire drawing box, and the axis of the pay-off wheel is vertical with respect to wire drawing direction of a cable; the one-way wire-fixing device comprises a first one-way wire-fixing device and a second one-way wire-fixing device; the first one-way wire-fixing device and the second one-way wire-fixing device are respectively configured with a first through hole and a second through hole; the cable orderly passes through the first through hole and the second through hole, and finally passes through the wire drawing assembly; the wire drawing assembly comprises a wire drawing wheel and a take-up roll; the wire drawing wheel is rotatably connected with the wire drawing box; and the take-up roll is installed on the wire drawing box. The invention provides the cable wire drawing structure capable of ensuring the wire drawing precision, capable of being adapted to different specifications and capable of completing good cable winding, and also provides a cable wire drawing method of the cable wire drawing structure.

Description

technical field [0001] The invention relates to the technical field of cable processing, in particular to a cable drawing structure and a cable drawing method. Background technique [0002] With the advancement of wire and cable processing technology, the conductors of power cables have begun to develop into a shaped wire stranded structure. The shaped wire stranded conductor has the characteristics of a small outer diameter layer and a smooth surface. And the application of shaped wire stranded conductors in power cables also has the advantages of reducing cable breakdown rate, smaller conductor outer diameter under the same cross-section, reducing the use of insulating materials and sheath materials, and improving conductor compression coefficient (0.98). [0003] Comparing the copper stranded conductor with shaped wire to the round compact conductor, under the same resistance, the plastic variation of copper is small, and the molecular structure distribution in the copper...

Problems solved by technology

[0008] (1) The design of the guide roller or the guide device is not good, and the effect of maintaining the tension of the cable drawing is low, which easily affects the normal operation and drawing accuracy of the cable drawing;

[0009] (2) Second, the wire drawing mechanism is simple in structure and poor in applicability. Usually, it can only support a single specification of cable drawing. If it is necessary to adapt to cables of different specifications, it is often necessary to replace the drawing roller substantially. Time-consuming;
