Apparatus for bending blade material

摘要

The invention relates to an apparatus for automatically bending a strip-shaped blade material to a predetermined configuration. An oscillating arm (3) provided with a movable clamp portion (2) for holding the blade material (1) at the front end portion thereof is attached to a base (4). A pair of stationary bits (5) are adjacently placed on the base (4) near an end of the movable clamp portion (2) of the oscillating arm (3) at a predetermined distance. The apparatus is provided with an oscillation driving mechanism (6) oscillating the oscillating arm (3) horizontally and a feeding mechanism (7) sending the blade material (1) forward along the oscillating arm (3). The blade material (1) is bent between one of the stationary bits (5) and the movable clamp portion (2) by oscillating the oscillating arm (3) horizontally. <MATH>
