A kind of cable sheath ring cutter and method for stripping cable

Abstract

The invention discloses a cable sheath ring-cutting knife. The cable sheath ring-cutting knife comprises a fixed press block, a movable press block, a connecting rod and a blade, wherein the fixed press block and the movable press block are arranged oppositely, the fixed press block is fixedly connected with a connecting rod, the movable press block is movably connected with the connecting rod and can perform reciprocating motion with respect to the fixed press block, and the blade is fixedly installed on the fixed press block and is perpendicular to the penetrating direction of a cable. The invention further discloses a method for removing a cable sheath by adopting the cable sheath ring-cutting knife. Firstly, the cable is put in a cable passing space, then the movable press block makes the blade cut into the cable sheath till the movable press block is matched with the fixed press block to tightly press the cable, the cable sheath ring-cutting knife or the cable is turned to achieve cable sheath ring-cutting, and finally the cable sheath is cut open at a ring-cutting position by using the blade or other tools, namely cable sheath removal can be achieved. The cable sheath ring-cutting knife is convenient to operate, the cable sheath removing efficiency is high, the sheath removing depth is uniform, an internal structure of the cable can be effectively prevented from being damaged during sheath removal, and the cable sheath ring-cutting knife is suitable for different diameters of cables and is good in universality, simple in structure and safe.

Description

technical field [0001] The invention relates to the field of power tools, in particular to a cable sheath ring cutter and a method for peeling the cable. Background technique [0002] When installing or overhauling power cables, it is necessary to peel off the cable sheath (including insulating layer, semi-conductive layer, copper shielding layer, outer sheath, etc.) Tools such as wallpaper knives are used to peel the skin, but because the blades of these knives are not installed firmly, they are easy to shake when cutting the cable skin, and the depth of the cut cable skin is uneven, especially when cutting the semi-conductive layer or copper shielding layer of the cable, due to the semi-conductive Layer and copper shielding layer are relatively thin, it is easy to penetrate the semi-conductive layer or copper shielding layer and destroy its internal structure when cutting, and because the copper shielding layer is relatively hard and the surface is smooth, it is easy to sh...

And there are certain security risks
