Device capable of preventing strand scattering during wire cutting

Abstract

The invention discloses a device capable of preventing a strand scattering during wire cutting. First connection arms are provided with a plurality of groups, and multiple sets of the first connectingarms are sequentially connected through first pin shafts and a connecting hole to form a flexible connecting arm; the first connecting arm at the head end is movably connected with a first shield through third pin shafts, a second connecting arm is arranged on one side of the first connecting arm at the tail end, and a plurality of ratchets are arranged on one side of the upper portion of the second connecting arm; a locking mechanism is arranged in the first shield, and the locking mechanism is matched with the ratchet on the second connecting arm; an unlocking device is arranged on one sideof the locking mechanism; a wire clamping device can be used independently or in combination. According to the device capable of preventing the strand scattering during the wire cutting, the multiplefirst connecting arms are arranged, the multiple first connecting arms are connected in sequence through the first pin shafts to form the flexible connecting arm, and when wires are pressed, a circular gap is formed between the first connecting arms and the second connecting arm, the contact area between the connecting arms and the wires is increased, and the phenomenon that the wire is scatteredis avoided.

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
