Description

Armored cable stripping device and armored cable stripping method

technical field

The present invention relates to armored cable stripping technology.

Background technique

Conductors of different materials are encased in a metal sheath with insulating material to form an armored cable. The armored cable is stronger than ordinary cables and can be bent at the same time. The metal sheath of the armored cable can be sheathed on the cable of any structure, which can significantly increase the mechanical strength of the cable, improve the corrosion resistance of the cable, enhance the tensile strength and compressive strength of the cable, make the cable not easy to be damaged, and extend the cable's durability. Service life, especially suitable for occasions susceptible to external force or erosion.

When stripping the cable, the protective layer of the cable needs to be cut with a knife, and then the protective layer of the cable is pulled off from the inner core of the cable. When the protective layer of the cable is made of non-metallic materials such as rubber, the operator can manually separate the protective layer of the cable after being cut from the inner core of the cable. However, the strength of the armored cable is very high, which significantly increases the difficulty of stripping the cable. It is greatly difficult for the operator to separate the cable protective layer from the cable inner core. Manual stripping is difficult to achieve. Use tools to clamp the metal sheath of the armored cable The tube is stripped. Since the tool is both the part that clamps the armored cable (the clamping force is perpendicular to the axis of the armored cable), and the part that applies the stripping force (the stripping force is parallel to the axis of the armored cable), the direction of force is inclined And unstable, so it is easy to damage the armored cable. Currently, there is a lack of a device that facilitates the stripping of armored cables.

In the present invention, the parts that clamp the armored cable are the top bolts, and the parts that exert the peeling force are the left baffle and the right baffle. Since the peeling force and the clamping pressure are no longer the same component, the direction of the jacking force of the jacking bolt will not change, and the direction of the peeling force of the left and right baffles will not change, so the direction of the force will not change. Sloped and unstable causing damage to armored cables.

The armored cable stripping method of the present invention uses tools instead of manpower to strip the cable. When stripping the metal protective tube at the end, selecting a suitable tool can easily generate sufficient pulling force, such as using a sleeve with a sufficient torque for rotating the nut When the nut drives the screw to rotate, the screw extends and rotates out of the first hinge shaft under the action of the bolt. force), which pushes the first hinge axis toward the second hinge axis, while keeping the third hinge axis away from the fourth hinge axis, which in turn causes the left and right flaps to pull the metal of the armored cable to the left and right, respectively protective tube.

By adopting the invention, the force applied to the metal protective tube of the armored cable is uniform and stable during peeling, and the force and the direction of force during the peeling process are uniform and stable, and the force will not change due to the sudden change of the force and the force of the force. The change of force direction can damage the inner core of the cable.

In a word, by using the present invention, the force and direction of force application in the peeling process are uniform and stable, the cable will not be damaged, the peeling efficiency of the armored cable can be greatly improved, the use is convenient, and it has good popularization and application value.
