Abstract

The invention relates to a numerical control electric screw press driven by a disk type linear motor. The numerical control electric screw press comprises a press body provided with a beam. A press body guide track, a sliding block hammer, a thrust bearing, a copper nut and a main screw are arranged on the press body. The press body guide track is fixed on the press body, the sliding block hammer is arranged on the lower portion of the beam and can slide on the press body guide track, the thrust bearing is fixed on the bottom of the beam, the copper nut is fixed on the sliding block hammer, one end of the main screw and the copper nut form a screw pair to drive the sliding block hammer to move linearly, and the disk type linear motor is arranged on top of the beam. The disk type linear motor comprises a flywheel rotor and a stator assembly. The stator assembly is fixed on the top of the beam and arranged at the bottom of the flywheel rotor, and the other end of the main screw is fixed at the rotary axis position of the flywheel rotor. A brake is arranged on the lateral side of the outer circumference of the flywheel rotor and brakes rotation of the main screw by braking the flywheel rotor. The numerical control electric screw press has the advantages of being convenient to maintain, low in energy consumption, small in noise, precise in control, high in safety performance and the like.

Description

[0001] technical field [0002] The invention relates to the technical field of numerically controlled electric screw presses, in particular to a numerically controlled electric screw press driven by a disc-shaped linear motor. [0003] Background technique [0004] 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 MULLE WEINGARTEN 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 ...
