Release device for an industrial machine for the bending of metal elements

A release device for industrial machines for bending metal elements by means of a plurality of sheet-pressing tools arranged over a supporting frame, the industrial machines comprising a longitudinal member to which said plurality of sheet-pressing tools are coupled by means of an inclined interface, said device comprising:

• clamping means comprising tightening means,
• a modular coupling interface configured to be located in between said clamping means and a wall of the machine, said modular coupling interface being configured for keeping said plurality of sheet-pressing tools in a locked position,
• wherein said clamping means comprises a plurality of clamping elements suitable for locking the modular coupling interface to an upper surface of the sheet-pressing tools, and is arranged in alternation to a plurality of actuators,
• wherein said actuators are configured to exert on the wall, when in action, a force opposed to a force exerted by said clamping elements, facilitating horizontal displacement of the clamping means,
• wherein said horizontal displacement enables the modular coupling interface to move vertically to allow the removal of the sheet-pressing tool, and
• wherein the tightening means is configured to house the actuators.
