Abstract
PURPOSE: To form the plural metallic materials into the desired bends with one machine, by holding and forcibly feeding the metallic material to the bend former waiting on a circular arc of a radius equal to the desired bending radius.
CONSTITUTION: Plural metallic materials like as the reinforcing iron bar 3, etc., are piled up one upon another to form a flat wall, and their tips are held by pinching with the pinch rollers 6. Meanwhile, the bend forming part 12a of the bend forming roller 12 is located on the circular arc of radius equal to the desired bending radius of the reinforcing iron bar 3. Next, by forcibly feeding the iron bars 3 in the direction C by the pinch rollers 6, the length of the iron bar 3 from the tip to the desired position can be bent into the desired radius by the bend forming part 12a of the bend forming roller 12 waiting ahead. The present method is also suitable for bending various metallic materials other than the bending work for the concrete reinforcing steel bar of various bending shapes and various bending angles.
