FIELD: plastic working of metals, namely sheet forming processes and equipment.
SUBSTANCE: die set includes movable upper plate with members for fastening on press slide; punch; die with bending protrusions. Punch is mounted on die through rotary unit. Bearing surface of punch in zone of transmitting effort is cylindrical one. Slides are mounted on bearing surface of punch. There are grooves on lateral surfaces of punch. Upper surfaces of slides and grooves are equidistant relative to bearing surface of punch. Rollers mounted on jaws of plate are arranged in said grooves with possibility of motion. Fixing members for orienting sheet blanks are mounted in die.
EFFECT: enhanced accuracy, lowered number of operations at making corrugations on sheet blank with use of standard press equipment.
