Description

Aluminum Strand Stripping Tool for Large Section ACSR

technical field

The utility model relates to a wire stripping tool, in particular to a tool for stripping aluminum strands of large-section steel-cored aluminum stranded wires.

Background technique

At present, the tools and tools often used for crimping aluminum-steel conductors include: bow saws, board files, bolt cutters, spiral cutters, hydraulic pump stations, etc. It is an important step for cable connection to strip the outer layer of aluminum strands of the steel core aluminum stranded wire with a bow saw or a spiral cutter before crimping. The main problems of stripping the outer layer of aluminum strands of steel-cored aluminum strands with saw bows or spiral cutters are slow speed, time-consuming and labor-intensive, and easy to damage the steel core. It is also easy to cause uneven sawing, loose strands of steel core, jumping up of aluminum strands, loose strands and other phenomena during cutting, which makes it difficult to thread through the pipe, increases the difficulty of work, and prolongs the operation time. In addition, the cutters with this function on the market can only strip the ACSR with a cross-section of 720 square millimeters at most, while the current domestic largest conductor cross-section is 1440 square millimeters. Layers peeled off.

The knife holder is an F-shaped structure, and its upper and lower two transverse plates are respectively the fixed plate and the supporting plate, and the fixed plate and the supporting plate are respectively provided with two rollers at intervals to form a four-point support. The inner surface of the vertical plate at the lower end of the tool holder is provided with continuous anti-slip protrusions. the

The beneficial effects of the utility model are:

1. The tool post of the utility model rotates 360° smoothly along the circumferential surface of the wire on the cutting track through the roller, so as to realize the circumferential cutting of the wire by the tool, which is convenient and fast. In addition, the supporting plate of the tool post can be adjusted up and down, and can adapt to different diameter ACSR.

2. The utility model adjusts the cutting depth of the cutter through the extension and contraction of the cutter rod of the fixed cutter, so as to complete the cutting of different layers of aluminum strands and ensure that the steel core is not damaged. the

3. The utility model is composed of two semicircular hoops for cutting track, which is convenient for the rollers to rotate on the cutting track, thereby ensuring the consistency of the cutting position. the

4. The knife rest of the utility model is an F-shaped structure, and its lower handle is provided with an anti-slip protrusion, which is convenient for cutting force and improves work efficiency. the

5. The utility model has the advantages of simple structure, convenient use, good stripping and cutting effect and low cost, and can be reused. It can strip any size of steel-cored aluminum strands from 720 to 1440. It is easy to popularize and implement, and has obvious economic benefits. the
