Abstract: The present invention relates to a spring manufacturing machine equipped with two motors, which includes a wire feeding motor, a tool operating motor, and a control unit for controlling functions of these motors. The spring manufacturing machine is provided with an auxiliary feed mechanism so that wire feeding rollers as well as tools such as a coiling tool, etc. may be operated by the tool operating motor, and is capable of operating the tool and wire feeding rollers in timed relation by the tool operating motor, without necessity for frequent starting and shutting down of the tool operating motor and wire feeding motor even in the case where complicated processing is to be imparted to springs.

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.
