Abstract
A sheet bending brake comprises a frame having a fixed jaw and a movable jaw. The fixed jaw defines a clamping surface and the movable jaw has a clamping surface movable between workpiece clamping and non-clamping positions relative to the clamping surface on the fixed jaw. A bending member is hingedly connected to the fixed jaw. A handle is pivoted to the frame. A plurality of axially extensible links are provided. Each link is pivoted at one end to the handle and at the other end to the movable jaw such that in one position of the handle, the links move the movable jaw out of clamping position, and in another position of the handle, the movable jaw is in clamping position. Each link includes an upper block connected to the frame, a shaft extending from the upper block and rotatable therein and threaded into a lower block pivoted to the movable jaw. The shaft has a socket connection in the upper end thereof accessible through an opening in the upper block.
