The invention discloses an intelligent CNC spring
machine used for
processing extension springs, compression springs, torsion springs, spiral springs and the like. The intelligent CNC spring
machine comprises a straightening mechanism, a wire feeding mechanism, a
pitch mechanism, a core seat mechanism, a knife seat mechanism and a
computer control system. The
pitch mechanism comprises a
pitch servo motor and a pitch
ball screw pair driving a pitch shaft to move; the core seat mechanism comprises a core seat lifting mechanism and a core rod core-pulling mechanism; and the knife seat mechanism comprises a plurality of sliding knife seats and knife seat driving mechanisms and can move along an arc-shaped track in a radial direction. The spring
machine is provided with five sections including a straightening section, a wire feeding section, a pitch section, a core seat section and a knife seat section according to the principle of spring formation, and has reasonable structure design and is driven by a full
servo and controlled by a computer so as to realize fully
closed loop control and be capable of reducing the
rejection rate of finished products. The intelligent CNC spring machine can be widely applied to the production of various extension springs, compression springs, torsion springs, spiral springs and the like, with simple operation, high
processing precision and high production efficiency.
