Abstract:
Sheet metal forming machine comprising:a machine frame, a first roller tool mounted on the machine frame for rotation about a first roller axis, a second roller tool rotatable about a second roller axis and interacting with the first roller tool, said second roller tool being mounted for rotation in a feed bearing, said feed bearing being for ito port movable and fixable in position in relation to the machine frame transversely to the first roller axis by means of a feed drive so that a feed position of the second roller tool relative to the first roller tool is adjustable, e-4a roller drive for at least one of the roller axes, a feed detector for detecting said feed positions of said second roller tool, a roller axis detector for detecting roller axes positions of said roller axes, a control adapted to control said feed drive and said roller drive, a memory associated with said control, said control being operable in a learning mode in which said feed positions and said roller axes positions are adjusted manually by an operator acting on a first adjusting element for feed positions and a second adjusting element for roller axes positions in the course of actual performance of a forming cycle on a work piece, said control when operated in said learning mode recording said feed positions detected by said feed detector and said roller axes positions detected by said roller axes detector and storing said detected feed positions and said detected roller axes positions in said memory, said control being further operable in a forming mode in which said control by reading the stored data in said memory automatically controls said feed drive and said roller drive in accordance with said feed positions and said roller axes positions stored in said memory.
