A wire cutting and anti-stripping device

Abstract

The invention discloses a wire cutting anti-strand device. There are several groups of first connecting arms, and multiple groups of first connecting arms are sequentially connected through first pin shafts and connecting holes to form flexible connecting arms; the first connecting arm at the head end passes through The third pin shaft is movably connected with the first shield, the first connecting arm at the end is provided with a second connecting arm, and the upper side of the second connecting arm is provided with several ratchets; the inside of the first shield is provided with a lock The locking mechanism cooperates with the ratchet teeth on the second connecting arm; one side of the locking mechanism is provided with an unlocking device; the wire cutting and anti-stripping device can be used alone or in combination. In the present invention, a plurality of sets of first connecting arms are provided, and the multiple groups of first connecting arms are sequentially connected through first pin shafts to form flexible connecting arms. The gap increases the contact area between the connecting arm and the wire, and avoids the phenomenon of loose strands of the wire.

Description

technical field [0001] The invention belongs to the technical field of electric power construction auxiliary equipment, and in particular relates to a device for preventing strands from cutting wires. Background technique [0002] The production method of the aluminum stranded wire is to use a cutting saw blade to cut the wire. If the wire is cut directly, it will cause the aluminum stranded wire to loose strands. In order to strengthen quality management and improve the construction technology level of power infrastructure projects, during the installation of soft busbars in substations, before the wires are crimped, the front wires of the aluminum tube openings need to be fastened with iron wire or aluminum wire to prevent loose strands during the wire crimping process. ; In order to avoid this phenomenon, but the iron wire or aluminum wire is easily deformed by the impact force generated when the aluminum stranded wire expands, resulting in the phenomenon of loose strands...

Problems solved by technology

It utilizes gears meshing with the racks on the outside of the pressing plate to realize fast binding of the wires through the rotation of the gears. However, during use, it was found that due to the different specifications of the wires, when the supporting plate and the pressing plate crimp the wires, the supporting plate and the pressing plate are different. A space similar to an ellipse is formed between the pressure plates, and there are gaps at both ends of the long axis of the ellipse, so that there are different degrees of loose strands on both sides of the wire, and the smaller the diameter of the wire, the more obvious the loose strands are, which is not conducive to the cutting of the wire
