How to remove burrs

Abstract

This invention provides a method for flattening burrs on an electric wire from which a portion of the coating has been removed, in an electric wire whose conductor is covered with a coating before stripping. [Solution] A deburring method for deburring a wire in which a rectangular cross-section conductor is covered with a film, and from which a portion of the film in the direction of extension of the wire has been peeled off, wherein the burrs on the first and second surfaces of the peeling boundary between the covered portion, which is the part of the wire in which the conductor is covered with a film, and the exposed portion, which is the part of the wire in which the conductor is exposed, are pressed by a first projection formed in a first shape and a second projection formed in a second shape, thereby deburring the burrs on the first and second surfaces of the peeling boundary.

Claims

1. A method for deburring a wire in which a rectangular cross-section conductor is covered with a coating, and a portion of the coating in the direction of extension of the wire has been peeled off, the method for deburring a wire, The burrs on the first and second surfaces of the peeling boundary between the covered portion, which is the part of the electric wire in which the conductor is covered by the coating, and the exposed portion, which is the part of the conductor that is exposed, are crushed by pressing them with a first projection formed in the first shape and a second projection formed in the second shape. How to remove burrs.

2. A deburring method according to claim 1, The first and second projections have a tapered shape that protrudes in a manner corresponding to the direction from the insulated portion of the electric wire to the exposed portion. How to remove burrs.

3. A deburring method according to claim 1 or 2, The first and second projections have a tapered shape that protrudes from the central part to both edges of the first and second surfaces of the peeling boundary. How to remove burrs.

4. A deburring method according to claim 1 or 2, By holding the electric wire with a clamp and pressing the first and second surfaces with the first and second protrusions, the burrs on the first and second surfaces of the peeling boundary are crushed. How to remove burrs.

5. A deburring method according to claim 4, The third and fourth surfaces of the peeling boundary are pressed by the third projection formed in the third shape and the fourth projection formed on the clamp, thereby crushing the burrs on the third and fourth surfaces of the peeling boundary while holding the electric wire. How to remove burrs.
