Study Of Servo-Press Control System

The press is one of the important manufacturing equipments, which is the main equipment in information products, electronic machinery, motor vehicles, and other industry. Traditional press has the small craft possibility, complicated structure, and manufacturing. Along with the development of mechanical processing field and the improvement of forming process, the press-research is toward efficient machine, high precision, high processing quality and flexible manufacturing. Servo press combines the easy operation, low cost and stable work of tradition, making full use of advantages of control and digital of servo motor, greatly improving the automation, flexibility and processing range of press.This paper from the existing traditional mechanical press equipment, combined with its existing shortage, and puts forward the different idea of press driven directly. On the one hand, the existing mechanical driven-press has complex equipment structure and poor efficiency and sensitivity; on the other hand, servo motor is stable and reliable, and has the advantages of quick action and high precision. Choose to use servo motor instead of mechanical transmission to drive the slider of press. Through the research of servo-control-system, determine the appropriate servo system and control-scheme. According to the control-system-scheme to attain the correct electrical system and choose the appropriate electronic devices to develop a feasible servo press. This paper explores the development of the large servo press and reaching the expected purpose, provides a theoretical and practical basis for the further development of the servo press.As a new type press, servo press has good control and meets the high efficiency, high precision, high flexible processing requirements and expands processing range and processing technology, improving the quality of the stamping press, the research of servo press is the main trend of development of press. Servo press has been developed to promote the further development of the industry. And enhance the manufacturing market competitiveness, and has achieved good economic and social benefit.
