A wire tightening device for multi-bundle wire stranding equipment

Abstract

The invention relate to a lead tightening device especially for a multi-beam lead stranding device. The device comprises a support rack and two lead positioning racks installed at the two sides of the support rack. Two L-shaped support columns are symmetrically installed at the middle part of the upper end surface of the support rack by bolts; and a wire through plate is welded between the two L-shaped support columns. Four lead holes are symmetrically formed in the wire through plate; and two tightening branched chains are symmetrically installed at the two sides of each of four lead plates of the wire through plate. Each tightening branched chain contains a tightening plate welded to the outer wall of the wire through plate and four tightening plates installed at the side wall of the wire through plate; the front ends of the four tightening plates form a lead tightening opening; and a limiting spring is installed between each tightening plate and the inner wall of the tightening plate. Because of different wire diameters of different leads, the sizes of the tightening openings can be adjusted automatically based on the limiting elastic forces of the limiting springs. According to the invention, the lead tightening transmitting function before multi-beam lead stranding can be realized. The lead tightening device has advantages of simple operation, high work efficiency, and wide application range and the like.

Description

technical field [0001] The invention relates to the technical field of cable processing, in particular to a special wire tightening device for multi-bundle wire stranding equipment. Background technique [0002] In the cable processing industry, from the stranding of copper wires after wire drawing to the processing of core wires into cables, cable stranding equipment is used everywhere. At present, the commonly used cable stranding equipment mainly includes cage stranding machine, disc stranding machine, fork stranding machine, frame stranding machine, tubular stranding machine and beam stranding machine, etc. These stranding machines are basically It can realize the single-wire twisting requirements of different wire diameters, but these twisting machines cannot realize the function of twisting multiple bundles of wires at the same time, resulting in the existing wire twisting equipment can only perform the single-wire twisting function, which has the disadvantages of slow...
