Abstract

Fixture for fixing the tools to the upper and lower toolplate of sheet metal bending brakes, comprising a clamp fixed to the respective toolplate and having a lower channel for receiving the tool shank, which is provided with a groove along its entire length, means for supporting the shank in said channel while leaving it free to slide along the channel, and means for locking the shank in said channel, in one of the opposing walls of the channel there are provided; parallel to the channel axis and in correspondence with the groove in the tool shank, at least two aligned holes into which there is inserted freely slidable a movable body having a dimension greater than the wall thickness; means for maintaining said movable body elastically pressed into said groove in the tool shank; and first means counteracting said elastic means to annul their pressure against said groove.
