Scattering-preventing tool special for lead wire cutting

Abstract

The invention relates to a scattering-preventing tool special for lead wire cutting and belongs to the field of mechanical machining devices. The scattering-preventing tool special for lead wire cutting comprises a butterfly-shaped bolt, an external clamp part, a rotary shaft, a die upper portion and a die lower portion, wherein the external clamp part is movably connected through the rotary shaft, and the butterfly-shaped bolt is installed on the side of the external clamp part. The die upper portion and the die lower portion are wrapped in the external clamp part. Compared with the prior art, the scattering-preventing tool special for lead wire cutting has the advantages of being simple in operation, flexible, convenient, durable and safe.

Description

Technical field [0001] The invention belongs to the field of mechanical processing equipment, and particularly relates to a special wire tool. Background technique [0002] Wire is a commonly used component in the machinery industry. In the long-term wire cutting and fixing work, we found the following problems: [0003] Except for the steel core in the middle of the traditional steel core aluminum stranded wire, the state of the remaining strands in the wire is left-handed or right-handed. Generally, the outermost aluminum wire strands are right-handed, which is easy to loose strands when cutting the wire. Often referred to as "lantern flower", it is difficult to insert the terminal, and in severe cases, the entire wire will be scrapped. [0004] In the process of replacing the isolating switch, due to economic considerations, there is no need to replace the herringbone lead wire, but the wiring terminal needs to be replaced. At this time, the old wire terminal end is cut. During t...

Problems solved by technology

[0003] Except for the steel core in the middle of the traditional steel-cored aluminum stranded wire, the state of the rest of the wire strands in the wire is left-handed or right-handed. Generally, the outermost aluminum wire strands are right-handed, and it is easy to loose strands when cutting the wire. The so-called "lantern flower" makes it difficult to insert the terminal, and in severe cases, the entire wire will be scrapped

[0004] In the process of replacing the isolating switch, due to economic considerations, there is no need to replace the herringbone lead wires, but the wiring terminals need to be replaced. At this time, the terminal ends of the old wires are cut. During the field operation, the old wires often break and cause the The herringbone lead wire has to be replaced as a whole, which not only wastes the wire material, but also greatly prolongs the working time and wastes manpower and material resources

[0005] It is difficult to insert the wire into the terminal after the strands are scattered, the insertion is not in place, and the contact is poor. Under the action of high current, it is easy to cause overheating of the crimping joint, which endangers the safe and stable operation of the equipment.

When replacing the equipment clamp, due to the traditional process when cutting the wire, it is easy to make the binding of the wire end not firm, and the wires are broken and loose. It is difficult to insert the equipment clamp, and there is no corresponding professional tool. When the wire is connected, the surface of the wire is damaged and the cutting is uneven, so that when the wire is put into operation, under the action of a large current, the temperature of the joint rises and the contact resistance increases. safe and stable operation
