Reshaping workpieces from sheet using tool with at least one shaping ram involves reducing friction between workpiece and tool near small shaping radii at least in some phases during reshaping

摘要

The reshaping method involves reducing the friction between the workpiece and the tool at least in some phases during reshaping in the region of shaping contours with small shaping radii. The workpiece is subjected to dynamic pressure in a pulsed manner in regions with small shaping radii. The pressure application can be electronically controlled or regulated. AN Independent claim is also included for the following: (a) an arrangement reshaping workpieces in the form of a sheet using a tool with at least one shaping ram.
