On the basis of summed up the general press feeding equipment and systems for power digital punch feeders automated transformation of the design process are discussed in the article. Control system design is the use of SCM AT89C52 through the program control XY direction two stepper motor driven ball screw agencies and the table coordination, so as to achieve the purpose of automatic feeding, and by means of keyboard and LCD to complete the start movement , stop and speed of the chose and other control operations.The stepper motor is the electrical pulses into angular displacement or linear displacement of the open-loop control components in the case of non-overload, the motor speed, the stop position depends only on the frequency and number of pulses of the pulse signal,without the impact of load changes ,a pulse signal to the motor plus ,the motor is turned one step angle.The existence of this linear relationship, And the stepper motor are only have periodic error without accumulated error characteristics, making in the speed , position etc control field use the stepper motor is becoming very simple.Automatic feeding device design is:rail design,selecting and checking;design, choice and checking of the ball screw; selection and checking of the motor.X-Y table:usually constitute by the rail seat, move the slider, table, the ball screw nut and the stepper motor and other components.The stepper motor as the actuator used to drive the ball screw, ball screw driven the movement of the slider and the table on the rail, to complete the linear movement of the table in the X, Y directions.The guideway, ball screw nut and stepper motors have been standardized.Production by specialized manufacturers,you can only need to according to select by the working load when in the design.Through the design to complete the system of mechanical transmission, as well as table moves in the XY direction,the design of the automatic feeding device and the control system design combined with each other to complete the automated transformation of the automatic feeding device in the general press.
