Abstract

The quick tool clamping system relates to a cornice brake in which there are rows of punches (2) and dies (1) and modular units consisting of intermediates (13) and clamping jaws (14) for the intermediates and jaws (29) for clamping punches, with the latter being operated by actuators driven by pneumatic cylinders (9), and is characterized in that:
  • a) in the intermediates and the jaws clamping the intermediates to the cursor (5) of the press there are channels (15,16) for feeding of the fluid under pressure to the actuator cylinder (9),
  • b) said channels lead to at least one hole (19,20) opening onto the opposing surfaces of each pair of intermediates and associated clamping jaw,
  • c) on at least one of the two opposing surfaces of each pair of intermediates and associated clamping jaw the associated hole (20) opens onto a groove (21) running horizontally in the surface and positioned at the same level as the hole (19) opening onto the opposing surface, and
  • d) in the circuit for supplying the fluid under pressure to every intermediate a valve (22) is inserted designed to intercept the flow of fluid towards the intermediate.
