Problems solved by technology

[0014] Therefore, for the actuation shaft that directly drives the punch up and down by such a servo motor, it is necessary to supply the electric energy for high-speed operation of the servo motor and the electric energy for punching, so the peak power of the control circuit for the servo motor will inevitably become very high. high

Embodiment Construction

[0058] Embodiments of the present invention will be described below with reference to the drawings.

[0059] figure 1 It is a longitudinal sectional view showing an essential part of an embodiment of a servo drive system (continuous processing system) of a press machine according to the present invention, figure 2 It is the right side view, and the servo drive system (continuous processing system) 1 of this press machine is used in the turret press machine 10 .

[0060] In the turret press machine 10, an eccentric shaft 20 is pivotally supported on bearing portions 12a, 12b provided on brackets 11a, 11b erected in parallel. On the eccentric shaft portion 20e of the eccentric shaft 20 located approximately in the center between the brackets 11a, 11b, the punch 22 is installed through the connecting rod 21, and by the rotation or rotation of the eccentric shaft 20, the punch 22 is moved along the punch through the connecting rod 21. The conduit 23 moves up and down, and the s...

Abstract

A servo drive system of a press machine has a pair of servo motors 30a and 30b which can generate necessary ram pressure by compositing and using a torque based on the same speed-torque characteristics. The servo motors 30a and 30b are symmetric with each other in a mirror image manner. The servo motors 30a and 30b are opposed to each other at opposite ends of an operation shaft 20 which vertically moves a ram 22. The servo motors 30a and 30b are integrally operated, thereby directly driving the operation shaft 20.

Description

[0001] This application is a grandson's divisional application filed on June 17, 2003, with application number 03813989.8, and the title of the invention is "Servo Drive System and Continuous Processing System in Stamping Machinery". The sub-divisional application was filed on July 21, 2009 Submitted, the application number is 200910151451.4, and the title of the invention is "servo drive system and continuous processing system in stamping machinery". technical field [0002] The present invention relates to a servo drive system for a press machine used, for example, in a turret press machine, and more particularly, to a continuous processing system for a press machine used in a turret press machine. Background technique [0003] Conventionally, generally in a press machine, an electric drive source using a servo motor has been used as a drive source for a punch. In press processing of such a press machine such as a press machine, since extremely large noise is generated dur...
