Cable metal shielding layer stripping device

Abstract

The invention discloses a cable metal shielding layer stripping device. The device comprises a driving system, a spring, gears, a needle body, a needle tip, a limiter and a supporting seat; the driving system is connected with the gears, and provides power for the gears; one end of the spring is connected with one end of the needle body, and the other end of the needle body is connected with the needle tip; the limiter is arranged between the needle body and the needle tip; the needle tip penetrates out of the limiter and is used for punching a cable; the gears are arranged on the two sides ofthe needle body, and drive the needle body to move up and down; and the supporting seat is arranged under the needle tip. By punching the cable, rapid stripping of a cable metal shielding layer can be achieved.

Description

technical field [0001] The invention relates to the field of stripping metal shielding layers of cables, in particular to a stripping device for metal shielding layers of cables. Background technique [0002] The conductive core of the fire-resistant cable is located in the middle of the cable, and the outside is first wrapped with insulating materials such as mica tape, and then wrapped with a metal shielding layer (also called a fire-resistant layer). The metal tube of this layer is usually aluminum or copper. In order to ensure the flexibility of the cable, often the layer of metal pipe needs to be made into a corrugated shape. Then the outer layer is wrapped with fireproof mud and related polymer sheath to make a cable. [0003] High-end fireproof cable products need repeated quality and reliability verification during the trial production process. At the same time, many trial products or failed products will be produced during the trial production process of new produc...

Problems solved by technology

[0003] High-end fireproof cable products need repeated quality and reliability verification during the trial production process. At the same time, many trial products or failed products will be produced during the trial production process of new products, including some that do not meet the design size requirements. Surplus products, and these products will face the problem of recycling

In the process of metal copper recycling, it is necessary to take out the mica tape and the polymer filler between the metal tube and the wire for recycling separately, and because the metal shielding tube is difficult to dismantle, it is more costly to use flame cutting and other methods. The method of stripping with a knife is because of the better plasticity of the metal tube, the hob is more difficult to cut, and it will cause the metal tube to be deformed and even completely destroy the inner copper wire

[0004] And because the outer dimensions of the bellows are uneven and not on the same plane, if the knife is shallow, it can only cut to the position of the wave peak of the pipe. If the knife is too deep, it will cut to the mica tape and polymer filling tape, causing the knife to get stuck. And it has a large wear and tear on the tool

This has led to a huge cost of sorting and recycling the finished and semi-finished cables with metal shielding tubes. Many aluminum shielding tubes are different metals from the copper core conductors, and there is basically no way to recycle them if they are not completely stripped.
