Abstract
Official abstract text for this publication.
An adjustment device of a punching device punches a workpiece on a die so that the workpiece is punched into a predetermined shape. The adjustment device includes a first drive mechanism that moves the punch or the die in a direction orthogonal to a punching direction, and a controller connected to the first drive mechanism. The controller brings the punch and the die into contact with each other by moving the punch or the die in four orthogonal directions in a plane perpendicular to the punching direction from an initial position where the punch is inserted into the punching die. The controller causes the first drive mechanism to move the punch or the die to a center position where a central axis of the punch and a central axis of the die are aligned with other.
First claim
Opening claim text (preview).
What is claimed is: 1. An adjustment method of a punching device which punches a workpiece placed on a die having a punching die with a punch so that the workpiece is punched into a predetermined shape, the adjustment method comprising: transmitting, using a controller, drive information to each of a first drive mechanism and a second drive mechanism communicably connected to the punch and the die to move the punch or the die; receiving, using the controller, position information and load information from respective sensors communicably connected to the punch and the die, based on the moving the punch or the die; positioning the punch and the die in contact with each other based on the moving of the punch or the die using the controller communicably connected to the first and second drive mechanisms, the moving of the punch or die being performed in four different orthogonal directions in a plane perpendicular to a punching direction from an initial position where the punch is inserted into the punching die; and positioning the punch or the die to a center position where a central axis of the punch and a central axis of the die are aligned with each other using the controller communicably connected to the first and second drive mechanisms, based on a distance between the initial position and each contact position in the four different orthogonal directions.
