Method and device for sheet metal bending or sheet metal cutting with reduced formation of flakes

A sheet metal working device for processing a sheet metal part, comprising:

• a sheet metal working tool, wherein the sheet metal working tool is a cutting blade or a press-brake jaw;
• an attachment, wherein the attachment is a cutting attachment if the sheet metal working tool is a cutting blade, and the attachment is a press-brake attachment if the sheet metal working tool is a press-brake jaw;
• and
• a blank holder, wherein the blank holder is configured to fix a sheet metal part disposed on the attachment for the processing of the sheet metal part, wherein the sheet metal working tool includes a sheet metal contact region which for processing a sheet metal part impacts the sheet metal part to be processed, and wherein the sheet metal working tool for processing the sheet metal part is configured to be moved laterally along the blank holder and the attachment, wherein a fluid allocation reservoir is disposed on the blank holder and provides a fluid and is configured to wet the sheet metal contact region with the fluid.

A method for retrofitting an existing sheet metal working device comprising:

• adding to the existing sheet metal working device a sheet metal working device including a flake formation reduction unit, a sheet metal working tool, an attachment, and a blank holder, wherein the sheet metal working tool includes a sheet metal contact region, for processing the sheet metal part, which impacts the sheet metal part to be processed, wherein the sheet metal working tool for processing the sheet metal is configured to be moved laterally along the blank holder and the attachment, wherein the sheet metal working tool is a cutting blade or a press-brake jaw, and the attachment is a cutting attachment if the sheet metal working tool is a cutting blade, and the attachment is a press-brake attachment if the sheet metal working tool is a press-brake jaw, and wherein the blank holder is configured to fix a sheet metal part, which is disposed on the attachment, for the processing of the sheet metal part, wherein the flake formation reduction unit includes a fluid allocation reservoir and a fluid, wherein the fluid allocation reservoir is disposed on the blank holder, and the fluid allocation reservoir is enriched with the fluid, wherein the disposal of the fluid allocation reservoir is performed in such a manner that the sheet metal contact region of the sheet metal working tool is wetted with the fluid at least when carrying out a downwards movement towards a sheet metal part to be processed.
