APPARATUS AND METHOD FOR THE FINAL PROCESSING OF A FORMING TOOL FOR A SHEET-METAL BODY PART

摘要

The invention relates to an apparatus for the final processing of a forming tool (5, 7) for a sheet-metal body part, in which, in a first operation for identifying a surface region (45) of a tool surface (9, 11) to be reworked, a sheet-metal part coated with a touch-up colour can be formed in a pressing operation by means of the tool and the surface region (45) to be reworked is detected with the aid of a colour impression of the sheet-metal part on the tool surface (9, 11), and then, in a second operation, the surface region (45) to be reworked can be reworked by a corresponding surface treatment. According to the invention, the apparatus has a processing device (31) which electronically detects the tool surface (9, 11) having the colour impression and, as a function of the intensity of the colour impression, determines the position and/or size of the surface region (45) to be reworked and accordingly reworks the latter.
