Abstract

A method for the automated processing of an end of a cable, which has an inner part and a sleeve surrounding the inner part, wherein one section of the sleeve is radially widened. The radially widened section of the sleeve is severed by the exertion of an axial cutting force in one region. A device suitable for implementing this method for the radial widening of a section of the sleeve and a cutting device having a first cutting body and a second cutting body, which can be moved toward each other in the axial direction with respect to the cable end and, as a result, sever the radially widened section of the sleeve in one region.

First claim

Thus, having described the invention, what is claimed is:

1. A device for processing the end of a cable with an inner part and a sleeve surrounding the inner part, such that a section of the sleeve is radially widened, comprising:
a foldback tube having a first end and a second end, and axially insertable into a gap between a radially widened section of the sleeve and the inner part for bending over said section of the sleeve;
a cutting device for cutting the sleeve, having a first cutting body and a second cutting body, the cutting device being axially aligned with said foldback tube, said first cutting body in slidable mechanical communication with said foldback tube first end, and said second cutting body coaxial with said cable and proximate said foldback tube second end;
a spring in mechanical communication with the foldback tube and the first cutting body of the cutting device in a spring-loaded manner, such that said spring is compressed when said first cutting body slidably traverses said foldback tube;
wherein the foldback tube is insertable into the gap through an axial movement of the first cutting body until the foldback tube reaches an axial stop, and a further movement of the first cutting body takes place in a movement relative to the foldback tube; and
wherein the first cutting body and the second cutting body are movable towards one another in the axial direction with respect to the cable end, thus severing the radially widened section of the sleeve in one region, the second cutting body having an opening, wherein the first cutting body penetrates into the opening of the second cutting body, cutting through the sleeve wherein the first cutting body and the second cutting body are movable towards one another in the axial direction with respect to the cable end, thus severing the radially widened section of the sleeve in one region, the second cutting body having an opening, wherein the first cutting body penetrates into the opening of the second cutting body, cutting through the sleeve.

2. The device of claim 1 , wherein the first cutting body is tubular in form and slideable over the section of the cable adjacent the end which is to be processed, such that, following the severing action, the first cutting body folds back the remaining radially widened section of the sleeve.

3. The device of claim 1 wherein the axial stop is a supporting sleeve surrounding the cable, coaxially aligned and concentric with said second cutting body, and limiting the section which is to be radially widened.

4. The device of claim 3 including a nipper coaxially aligned with said second cutting body and located between said supporting sleeve and said end of said cable, said nipper presses the section of the sleeve which is to be radially widened locally into the inner part of the cable.

5. The device of claim 1 including a severing device coaxial with said second cutting body and located between said supporting sleeve and said end of said cable, and adjacent said nipper, said severing device moving radially inwards for severing an outer layer of the inner part and/or an outer layer of the outer part of the cable.

6. The device of claim 2 wherein the axial stop is a supporting sleeve, coaxially aligned and concentric with said second cutting body, surrounding the cable and limiting the section which is to be radially widened.

7. A method for the automated processing of an end of a cable with an inner part and a sleeve surrounding the inner part with a device according to claim 1 , including radially widening one section of the sleeve, and severing the radially widened section of the sleeve in one region through the application of an axial cutting force.

8. The method of claim 7 , including radial widening said section through the application of radial forces in a partial region of said section.

9. The method of claim 8 , including bending over said section of the sleeve through the application of axial forces.

10. The method of claim 9 , including removing an outer layer of the sleeve prior to the radial widening of an inner layer of the sleeve in the section of the sleeve which is to be radially widened.

11. The method of claim 7 , including bending over said section of the sleeve through the application of axial forces.

12. The method of claim 7 , including removing an outer layer of the sleeve prior to the radial widening of an inner layer of the sleeve in the section of the sleeve which is to be radially widened.

13. The method of claim 7 , including removing an outer layer of the inner part from an inner layer of the inner part following a radial widening of the section of the sleeve, and exposing a corresponding section of the inner part.

14. The method of claim 7 , including removing an outer layer of the inner part from an inner layer of the inner part following a radial widening of the section of the sleeve, and exposing a corresponding section of the inner part.
