Description

Cable peeling knife

Technical Field

The utility model belongs to the technical field of the cable is retrieved and processing and specifically relates to indicate a cable skinning knife.

Background

The conductors in the cable are generally made of copper, which has a very high recycling value, and the copper core is often wrapped by various materials, such as a rubber protective sleeve and a metal shielding layer, and the cable needs to be peeled off to separate the copper core during recycling. In order to improve the efficiency, the prior multi-purpose peeling machine peels.

The skinning knife used by the existing skinning machine cannot control the depth, not only can damage the metal conductor in the cable, but also can reduce the service life of the skinning knife and increase the skinning resistance.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

An object of the utility model is to provide a cable skinning knife avoids skinning knife and inner core contact and causes inner core damage or tool bit life to descend. In order to achieve the above purpose, the utility model adopts the following technical scheme:

(II) technical scheme

A cable stripping knife comprises a knife bar, wherein a convex knife head is arranged on one side of the knife bar, a knife edge of the knife head is obliquely arranged, and the bottom of the knife bar extends obliquely downwards to one side of the knife head and is intersected with the knife edge to form a knife point; the bottom of the cutter bar is provided with a roller cavity, a roller is fixed in the roller cavity, the bottom of the roller protrudes out of the roller cavity, and the cutter point of the cutter head is 0.5-1mm higher than the bottom of the roller.

Further, the opening angle of the blade is 15-20 degrees.

Further, the angle of the tool nose is 25-40 degrees.

Further, the diameter of the roller is 3-8 mm.

(III) advantageous effects

Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, set up the gyro wheel at skinning knife top, make the gyro wheel contact all the time with the inner core of cable, effectively avoid skinning knife and inner core contact and cause the inner core to damage or tool bit life to descend, the gyro wheel constantly rolls at the cable in-process of marcing simultaneously, can not produce great friction and consume the energy with the inner core, overall structure is simple, convenient to use.

The present invention will be further described with reference to the accompanying drawings and the detailed description.

Referring to fig. 1, a cable peeling knife includes a knife bar 1, a protruding knife head 11 is arranged on one side of the knife bar 1, a knife edge 111 of the knife head 11 is obliquely arranged, and the cutting angle of the knife edge 111 is 15-20 degrees to ensure the peeling effect; the bottom of the cutter bar 1 extends downwards towards one side of the cutter head 11 in an inclined way to intersect with the cutting edge 111 to form a cutter point 112, and in order to prevent the cutter point 112 from penetrating into the outer skin 32, the angle of the cutter point 112 is 25-40 degrees;

the bottom of the cutter bar 1 is provided with a roller cavity 12, a roller 2 is fixed in the roller cavity 12, the diameter of the roller 2 is 3-8mm, the bottom of the roller 2 protrudes out of the roller cavity 12, and the cutter point 112 of the cutter head 11 is 0.5-1mm higher than the bottom of the roller 2, so that the outer skin 32 is cut and the inner core 31 is not scratched.

The utility model discloses an application principle does: when peeling, firstly, a section of the outer skin 32 is manually peeled off to expose the inner core 31, and then the cutter bar 1 is moved downwards until the roller 2 is contacted with the inner core 31, so that the cutter point 112 is not contacted with the inner core 31, the inner core 31 is protected, and the service life of the cutter head 11 is prolonged; then, the feeding mechanism is started, the cable 3 continuously moves towards the blade 111, the outer skin 32 is automatically broken, the roller 2 is tightly attached to the inner core 31, and friction is small.

The utility model discloses a design point lies in setting up the gyro wheel at skinning knife top, makes the gyro wheel contact with the inner core of cable all the time, effectively avoids skinning knife and inner core contact and causes inner core damage or tool bit life to descend, and the gyro wheel constantly rolls at the cable in-process of marcing, can not produce great friction and consume the energy with the inner core simultaneously, and overall structure is simple, convenient to use.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
