Abstract

On the machine bed are two pillars which can be moved horizontally towards or away from each other to suit the length of the workpiece, e.g. a metal bar; and each pillar supports an anvil on which the bar rests. Above each anvil is a roller forming a bending die, and a lever moving another roller to bend the bar round the die. In the space between the two pillars is a clamp used either to hold the bar or to rotate it through a desired angle. Useful in the automatic mfr. of antiroll bars for cars. Each pillar (27) supports anvil (11) on which bar (12) rests. Two work cylinders (14) each move a lever arm (15) carrying a bending roller (16), which bends bar (12) onto roller die (32) so two bends are made simultaneously or successively. Clamp (13) includes a pneumatic cylinder (45) pressing two clamping rollers (42) against bar (12), but the clamping pressure can be partly released so a hand lever can rotate bar (12) through a desired angle between bending operations.
