The invention relates to an arc-shaped motor-driven
numerical control electric
screw press, which comprises a
machine body provided with a cross beam. The
machine body is provided with a
machine body guide rail, a slider hammerhead, a
thrust bearing, a
copper nut and a main screw. The machine body guide rail is fixedly arranged on the machine body; the slider hammerhead is located at the lower part of the cross beam and can slide on the machine body guide rail; the
thrust bearing is fixedly arranged at the bottom part of the cross beam; the
copper nut is fixedly arranged on the slider hammerhead; one end of the main screw and the
copper nut form a screw pair to drive the slider hammerhead to do a
linear motion; and the top part of the cross beam is provided with an arc-shaped motor. The arc-shaped motor comprises a
flywheel rotor and a
stator module, wherein the
stator module is fixedly arranged at the top part of the cross beam, and the other end of the main screw is fixedly arranged at the rotating axis of the
flywheel rotor. The bottom part of the
flywheel rotor is also provided with a
brake, and the flywheel rotor is braked by the
brake to
brake the main screw to rotate. The arc-shaped motor-driven
numerical control electric
screw press provided by the invention has the characteristics that the maintenance is convenient, the
energy consumption is low, the control precision is more accurate and the safety is higher.
