Problems solved by technology

[0002] Most of the rotary head presses driven by the traditional AC asynchronous motor with gear reduction and crank slider mechanism use the crank slider mechanism. Due to the large size of the crank slider mechanism, the rigidity of the press is poor; in addition, because the AC asynchronous motor cannot adjust the speed , resulting in a fixed and single working mode, it is very difficult to achieve speed change through this transmission system, the process adaptability is poor, and it cannot meet the high requirements for energy saving, servo flexibility, high efficiency and precision of stamping equipment

Embodiment Construction

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] The core of the present invention is to provide a dual-motor helical pair direct-drive rotary head press. The direct-drive stamping system replaces the traditional crank-slider classic mechanism stamping system, which can easily change the movement direction and speed of the actuator. . The biggest feature of this system is to give full play to the characteristics of the AC servo motor, transform all the control problems to the control of the AC servo motor, it can easily realize computer control, and has strong adaptability ...

Abstract

The invention relates to a dual-motor screw pair direct drive type turret punch press comprising a punch. A screw is arranged in the punch, two threads different in rotation direction are formed in the upper portion and the lower portion of the screw respectively, the upper thread is matched with a first screw nut, and the lower thread is matched with a second screw nut. The first screw nut is fixedly connected with a rotor of a first servo motor, and the rotor of the first servo motor and a stator thereof are mounted on an upper box body in a matched manner. The second screw nut is fixedly connected with a rotor of a second servo motor, and the rotor of the second servo motor and a stator thereof are mounted on a lower box body in a matched manner. The bottom of the screw passes through a bearing end cover to be connected with a punch body. The dual-motor screw pair direct drive type turret punch press has the advantages of safety, stability, reliability, high cost performance and improvement in static and dynamic performance.

Description

technical field [0001] The invention relates to a press, in particular to a double-motor screw pair direct-drive rotary head press. Background technique [0002] Most of the rotary head presses driven by the traditional AC asynchronous motor with gear reduction and crank slider mechanism use the crank slider mechanism. Due to the large size of the crank slider mechanism, the rigidity of the press is poor; in addition, because the AC asynchronous motor cannot adjust the speed , resulting in a fixed and single working mode, it is very difficult to achieve speed change through this transmission system, the process adaptability is poor, and it cannot meet the high requirements for energy saving, servo flexibility, high efficiency and precision of stamping equipment. [0003] The idea of ​​direct drive is a new type of servo control method that has been continuously developed in various fields in recent years. The traditional crank-slider classic mechanism stamping system is rep...
