Embodiment Construction

[0036] FIG. 3 is a theoretical diagram showing the complete tooling (punch) mounted on the top plate 16 according to the invention. In this figure, the top plate is a movable plate and the bottom plate is a fixed plate. It is entirely possible that the top plate is a fixed plate and the bottom plate is a movable plate. The individual components referenced Ai each consist of an intermediate portion 26 and corresponding clamps 28 for the intermediate portion 26, which are arranged in groups to form a module. In the particular embodiment shown, the adjacent jaws are grouped in threes so as to form four modules M1, M2, M3 and M4, each module consisting of three parts consisting of a jaw and an intermediate portion AI composition. Depending on the tools used and the order in which the tools are executed, of course other structures can also be used.

[0037] This figure shows in a simplified manner the mechanisms Bi, Ci provided at the end of each intermediate part 26 for pivotin...

Abstract

The invention relates to a bending press comprising a bottom panel, a moving top panel, N bending-tool clamps, each clamp being mounted to pivot about a common axis, and means for causing the clamps to pivot. The means for causing the clamps to pivot comprise: a plurality of actuators each suitable for taking up two states; a plurality of transmission means for transmitting the state of each actuator assembly to a plurality of adjacent clamps, in such a manner each clamp is associated with a single actuator; and means for separately controlling the state of each actuator between a first state which brings the clamps associated with the actuator into a position for clamping the bending tool, and a second state which brings the clamps associated with the actuator into a position for removing said bending tools.

Description

technical field [0001] The present invention relates to a press brake, and more particularly to a system for clamping bending tools to the top plate of a press brake. Background technique [0002] Referring first to accompanying drawings 1, 2A and 2B, they are descriptions of the main components of a press brake of the prior art type. [0003] As shown in FIG. 1 , the press brake includes a fixed bottom plate 12 , a vertical frame 14 , and a movable top plate 16 , and the top plate 16 can move vertically relative to the fixed bottom plate 12 . The top plate 16 is moved by means of two control actuators 18 and 20 . [0004] The fixed base plate 12 has a press-bending die such as 22 fixed thereon, and the right part of a die is perpendicular to a V-shaped plane in the figure. The movable top plate 16 is used to carry a bending tool or punch 24 . Each punch 24 is mounted to the top plate 16 by being clamped between a fixed or intermediate portion 26 which is removably mounte...
