Abstract

The invention discloses a numerical control electric screw press driven by a permanent magnet synchronous linear servo motor. The numerical control electric screw press comprises a machine body, a machine body guide rail, a sliding block hammer, a copper nut, a main screw, the permanent magnet synchronous linear servo motor and a numerical control system, wherein the upper end of the machine body is fixedly provided with a cross beam; the machine body guide rail is fixed to the machine body; the sliding block hammer is located at the lower portion of the cross beam and can slide on the machine body guide rail; the copper nut is fixed to the sliding block hammer, and one end of the main screw and the copper nut form a screw pair to drive the sliding block hammer to conduct linear motion; the permanent magnet synchronous linear servo motor is arranged on the top of the cross beam and comprises a flywheel rotor and a stator assembly which is fixed to the top of the cross beam, and the other end of the main screw is fixed to the rotating axis of the flywheel rotor. The numerical control electric screw press has the characteristics of being convenient to maintain, low in energy consumption and noise, higher in control precision and safety performance, and the like.

Description

technical field [0001] The invention relates to the technical field of presses, in particular to a numerically controlled electric screw press driven by a permanent magnet synchronous servo linear motor. Background technique [0002] The electric screw press was born in Germany in the 1840s. It is known as a major technological breakthrough equipment and a leap in the history of screw press development. At present, companies such as MULLEWEINGARTEN and LASCO in Germany use frequency conversion technology to achieve a certain batch of production. In 1980, our country successfully developed the first generation J58D-100 electric screw press jointly by Hubei Forging and Huazhong University of Science and Technology. The characteristic of this model is that there are few transmission links, but it is necessary to design a special motor with low speed and high torque. The wear of the screw guide sleeve will affect the air gap of the motor, the motor is prone to failure, and the ...
