Abstract

The invention provides a numerical control forming method for an automatically fed-in forge piece, which is characterized by comprising the following steps: firstly, measuring numerical values of the comprehensive rigidity of a helical press machine and a die: inputting the angular velocity omega c of a motor; when the angular velocity value of the motor is equal to the omega c value, striking; according to the pressure value F displayed on a tonnage meter, computing the comprehensive rigidity values C of the helical press machine and the die according to a formula; then, controlling a robot arm by a controller to put a workpiece between dies of the helical press machine by control components and implementing the numerical control forming of the forge piece: (1) inputting the operating data V, A, H0, H, B0, B, sigma s, C, mu and J and computing the stress coefficients according to the formula; (2) feeding in the workpiece by controlling the robot arm according to the B0; (3) computingthe needed motor speed omega according to the formula by utilizing the control components, further controlling actions of the motor; when a motor speed value is detected to be equal to omega, controlling the motor to rotate at the speed of omega; and moving a sliding block downwards to strike. The forge piece which is machined by adopting the method provided by the invention has the advantages ofhigh accuracy, energy conservation, high efficiency and high automaticity.
