Procedure for forming corner section bounded on three sides from flat plate entails forming side walls of component in transition region and in corner region over entire height to bear upon form faces of work tool

摘要

The procedure for forming a corner section bounded on three sides entails in one of its stages forming the side walls of the component in the transition region and in the corner region(10) over its entire height(206) to bear upon the form faces(36) of the work tool(16) directly adjacent to the corner region to be manufactured. An Independent claim is included for a plant for forming a corner section bounded on three sides on a flat plate component in which the height(212) of the form faces of the tool is the same or greater than the height(206) of the side walls of the component or height(213) of the projection(194) in the corner region.
