Development Of Stamping Automatic Feeding And Unloading System For Stainless Steel Pot

Stamping is one of the important forming methods of stainless steel, stamping production line of stainless steel pot is the mainly composed of feeding and unloading system and punch. As punch feeding-and-unloading's operators, working conditions have certain risk. With constantly improvement of the production efficiences and shortage of the labor, more and more urgent does stainless steel pot body relised automatic feeding-and-unloading needs.This paper outlines metal punch forming and automatic feeding system. Furthermore, it proposes series of problems and development trend in the field to the present conditions of stainless steel pot automatic production line system.Based on the study of present situation and the development trend of latest technology of stamping automatic feeding and unloading system, this paper determined the basic design ideas of the stainless steel products stamping feeding and unloading system. Secondly, the mainly contents of this paper includes formulated whole plan of the stainless steel pot stamping automatic feeding and unloading system, the cylinder as the main actuators, PLC control system, realize beat movement of continuous discs's elevator, on edge, centering, conveying, unloading, detailed designing and calculating structure and working principle of each components in feeding and unloading system,analyzed role of each component in the whole feeding and unloading system. Then, analyzed the pneumatic and vacuum system of the stamping automatic feeding and unloading system, optimized and designed pneumatic and vacuum system for stainless steel pot stamping automatic feeding and unloading system, and optimized and designed the buffer circuit,pressure control circuit vacuum circuit and vacuum circuit. Finally, optimized and designed control system for stainless steel pot punching feeding and unloading system. Through the quantity of I/O and the power calculation to choose the of PLC, adopted the way of the Siemens PLC S7-200 CPU224 connect extension module of EM221,EM223, to design the control system, listed the key part of the Sequential Function Chart, writed the control program of this feeding and unloading system by used the ladder-diagram form.
