Abstract:
1. A bending press comprising: a bottom panel; a top panel; one of the panels being movable vertically relative to the other; N bending-tool clamps, each clamp being mounted on one of said two panels to pivot about an axis common to all said bending tool clamps for clamping bending tools, said bending tool clamps forming a plurality of adjacent groups of adjacent clamps, the number of groups being less than N; n actuator assemblies (1<n<N), each actuator assembly being adapted to take up one of two different states; n transmission means for transmitting the state taken by each one of said n actuator assemblies to one of said groups of adjacent bending tool clamps in such a manner that each bending tool clamp is associated with a single actuator assembly; and means for separately controlling the state of each actuator assembly, said two states consisting of a first state, wherein the clamps associated with sad actuator assembly is brought to a position for clamping a bending tool, and a second state wherein the clamps associated with said actuator assembly is brought to a position for removing said bending tools.
