Abstract
A bending apparatus (10) includes an upper first die (11), an upper second die (12), a lower die (13), a control unit (20), an upper first moving mechanism (21), an upper second moving mechanism (22), a lower moving mechanism (23), a holding die (31), and a moving and rotating mechanism (32). The lower die (13) is moved in an upper direction after the upper first die (11) and the upper second die (12) are moved to the front, whereby four coil segments (4) are bent. When the upper second die (12) is moved to a first withdrawal position in the rear direction after the four coil segments (4) are bent, a working space for the holding die (31) is ensured.
