Abstract (en)
The invention relates to a device for two sided incremental sheet forming comprising a sheet plate clamp frame (2) for gripping a sheet (4) around its perimeter, supports (3) for holding said clamp frame (2) on a base plate (1), an upper forming tool (5) above the sheet (4), a lower forming tool (6) below the sheet (4) and means (7) for synchronised moving said tools facing each other. According to the invention the means (7) for synchronised moving the forming tools is a mechanical movement copying device and there are means for moving the lower forming tool (6) on the surface of the base plate (1) according to axes X and Y. The means for moving the lower forming tool (6) on the surface of the base plate (1) contains at least one ball transfer unit (8), which may be provided with an electric, mechanic, pneumatic or hydraulic drive.
