Arc-shaped motor-driven numerical control electric screw press

Abstract

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.

Description

Technical field [0001] The invention relates to the technical field of screw presses, in particular to a numerical control electric screw press driven by an arc 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 is a leap in the history of screw press development. At present, companies such as MULLE WEINGARTEN and LASCO have adopted frequency conversion technology to achieve a certain mass production. In 1980, the first generation of electric screw press J58D-100 was successfully developed by Eduang and Huazhong University of Science and Technology in my country. The feature of this model is that there are few transmission links, but it is necessary to design a low-speed, high-torque special motor. After the screw guide sleeve is worn, the air gap of the motor will be affected, the motor is prone to failure, and the maintenance is not easy; the impact on the power grid du...
