Sheet bending brake

摘要

A sheet bending brake comprises a first longitudinally extending member having a clamping surface and a second member for bending a workpiece clamped on said clamping surface extending longitudinally with respect to said first member. Each of the first and second members has substantially the entire length of the longitudinal edges thereof formed with longitudinally spaced intermeshing integral projections. The projections on the second member have a plurality of aligned openings. A hinge pin extends through the openings of the second member. The second member includes an integral upper tubular portion and integral upper portion comprising an outer wall that extends upwardly and outwardly from a vertical wall of the lower portion; an integral horizontal upper wall; an integral rear wall that extends downwardly and inwardly to the front edge of the upper flange.
