WELDING DEVICE FOR STRETCH BENDER

摘要

PURPOSE: A welding machine for a stretch bender is provided to prevent overlapping of a flange portion of a shaped beam and thus to remove the need of equipment for aligning the flange portion in a following process. CONSTITUTION: A welding machine for a stretch bender comprises a back-and-forth moving unit(110) and a welding unit(130). The back-and-forth moving unit is installed at the front of a bending mold(30) and moved back and forth relative to the bending mold by the driving force of a cylinder. The welding unit is installed in the back-and-forth moving unit and moved back and forth by the driving force of the cylinder. The welding unit welds a flange portion(5) of a shaped beam(3) formed through the bending mold, thereby preventing overlapping of the flange portion when the shaped beam is ejected.
