Abstract:
1. A tool holder for a press brake, the tool holder having a tool-mount channel configured for receiving a tang of a press brake tool, the tool holder comprising: a) a driver; b) a push plate to which the driver is operably coupled, the push plate being mounted on the tool holder so as to be moveable between a first configuration and a second configuration, wherein the driver is adapted for being operated so as to move the push plate from its first configuration to its second configuration; and c) a pusher member mounted on the tool holder so as to be moveable between an open position and a closed position, wherein a desired end region of the pusher member extends into the tool-mount channel when the pusher member is in its closed position, the pusher member being operably coupled with the push plate such that when the push plate is in its first configuration the pusher member is in its closed position and the push plate provides resistance against the pusher member being moved into its open position, and wherein the pusher member comprises a rigid body mounted slidably in a bore extending through a block of the tool holder.
