Title: Method for punching and device therefor
Inventor: TAKATSU MASATO
IPC: B21D37/14
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To punch by efficiently correcting a work corresponding to the deviation amount of the work at a suitable work working position in the time of positioning the work. SOLUTION: In a time of positioning a work W at a work working position between a punch 3 and a die 9 with a work moving and positioning device 13, the direction and the deviation amount of the work W from overshooting from the work working position are detected with a clamp position detector 23, based on the overshooting direction and the deviation amount, a die holder 27 is moved with a holder moving device 29 to the same direction with the positioning direction of the work W. Because the difference of the real work working position of the die holder 27 and the target working position of the work W is made smaller during overshooting of the work W, punching can be executed even without waiting until completing of correcting the overshooting, so the work W is punched efficiently while raising the precision of working.
