Abstract
A portable sheet bending brake has a support frame with spaced longitudinally extending rails and a plurality of frame sections interconnecting the rails. A clamp member is carried by the lower arms of the frame sections, and an anvil member is carried by arms pivotally coupled to the upper arms of the frame sections. A bend member is pivotally mounted to the clamp member for bending over the anvil member sheet material clamped between the anvil and base members. A pair of longitudinally spaced handles are pivotally mounted to the bend member for pivoting into a channel on the bend member out of position to facilitate transport and storage of the brake. A shaft extends between bearings on the frame section arms, and has diametrically opposed longitudinally extending channels. Eccentric cams are received on the shaft, with diametrically opposed lugs received in the channels for automatically timing the cams with respect to the shaft, for pivoting the arms and the anvil member into clamping engagement with the base member. A stand supports the frame above the ground, and a table is mounted to the stand by four-bar linkages for movement between a lowered position beneath the brake and a raised position adjacent to the bend member while maintaining horizontal orientation of the table.
