    摘要: In a multistep bending machine, a movable apron (LA) provided with a movable tool (D) is moved in a multistep manner up and down toward a fixed apron (UA) provided with a fixed tool (P) by a hydraulic system including a novel die-axis drive mechanism (DDM), when a foot switch (FS) is kept depressed.In addition, an interference prevention device (IPA), a bending speed determining device (SDA), a tool distance determining device (TDA), a backgage stopper positioning device (SPA), and a backgage stopper pull-back distance controlling device (PDC) are all incorporated in the bending machine to realize a full automatic multistep bending operation.
