PURPOSE: A bending machine for U-shaped bolts is provided to increase productivity by bending multiple bolts in one cycle because guide rollers are formed in multiple stages. CONSTITUTION: A bending machine for U-shaped bolts comprises a workbench (2), a mold fixing unit (4), a mold (8), a bolt fixing shaft (10), guides (12), guide rollers (22), a first setting handle, a second setting handle, a third setting handle, pointing bars (16), and a sensor. The pointing bars are coupled to the upper part of the guides to move with the guides. When sensor detects the pointing bars, a lamp is turned on. Accordingly, a gap between the guides set by the first setting handle can be equally applied to next time. |
