Abstract
The method involves monitoring the metal sheet material (110) during reforming process in press-bonded material deforming tool (200), by a sensor (400). The separation of metal sheet material at defined location is performed by separation device of press-bonded material deforming tool, if the critical state generated due to increased flow of material in reforming process is recognized by sensor. An independent claim is included for a press-bonded material deforming tool. USE: Method for reshaping metal sheet material e.g. door outer metal sheet for motor vehicle chassis, in press-bonded material deforming tool (claimed) e.g. deep-drawing tool. ADVANTAGE: The desired reshaping of metal sheet material in deforming tool is achieved at low cost. The drawings show the plan view of manufactured metal sheet mold and sectional view of the material deforming tool.
