Abstract
The present invention relates to an apparatus for raising hooks of semi-finished springs, which includes a rocking arm arranged to be pivotally movable between an upper and a lower positions and having a pair of lateral semi-finished spring holding pieces at its forward end portion for transferring the semi-finished springs manufactured by a spring manufacturing machine towards a hook raising section provided above a spring discharge opening formed in a table of the apparatus, a clamping unit for fixedly clamping the semi-finished spring holding pieces which have been transferred to the hook raising section, a rotational position control member which rotates the semi-finished spring held between the semi-finished spring holding pieces for its positional control, and a pair of slide members on which hook raising tools are mounted and which are adapted to freely advance towards or retracted from the hook raising section. The apparatus is capable of automatically discharging the finished springs through the discharge opening by opening the pair of lateral holding pieces after accurately effecting the hook raising of the semi-finished spring above the spring discharge opening of the table through the positional control of the semi-finished springs.
