Method and wire processing machine that produces shaped parts from insulated flat material

A method of producing straight or bent shaped parts from insulated flat material having an electrically conducting carrier material sheathed by an electrically insulating insulation layer, comprising:

• 1) drawing the insulated flat material from a material supply by a draw-in device and processing in the wire processing machine to form a straight or bent shaped part of insulated flat material;
• 2) separating the shaped part from the supplied insulated flat material in a cutting operation, wherein
• before the shaped part is separated from the supplied flat material, part of the insulation layer is removed from the electrically conducting carrier material in at least a portion of the insulated flat material in a stripping operation,
• stripping tools on opposite side faces of the flat material are fed in the direction toward the side faces to a working position in which the stripping tools are in engagement with the insulation layer, and
• the stripping tools and the flat material are moved relative to one another parallel to a passage axis;
• and
• 3) synchronously with the feeding of the stripping tools on each side of the flat material, feeding at least one supporting element of a supporting device in the direction toward the flat material and bearing with a supporting face against the flat material in an immediate vicinity of an engagement position of the stripping tool when the stripping tool is in working position.

A wire processing machine that produces straight or bent shaped parts from insulated flat material, comprising:

• a draw-in device that draws the flat material from a material supply and conveys the flat material parallel to a passage axis;
• an alignment device that aligns the flat material;
• a cutting device that separates the shaped part from the supplied insulated flat material;
• an integrated stripping device that strips portions of the insulated flat material before the shaped part is separated from the supplied flat material,
• wherein the stripping device has on opposite sides of a passage axis at least one stripping tool that can be fed by a feed axis of the wire processing machine from a neutral position into a working position in which it is in engagement in a material-removing manner with the insulation material,
• on each side of the passage axis there is arranged at least one supporting element of a supporting device, which supporting element can be fed in the direction toward the flat material by the feed axis synchronously with feeding of an associated stripping tool and is configured to bear with a supporting face against the flat material in an immediate vicinity of the engagement position of the stripping tool when the stripping tool is in the working position.
