Abstract

The present invention relates to a device for bending a bracket for a hydraulic breaker, which enables a bracket for a hydraulic breaker having excellent durability against vibrations or external impacts to be produced by sequentially bending a thick bracket (plate) into a U-shape, and which can reduce manufacturing costs and increase productivity by simplifying the overall manufacturing processes.
