Motion setting method for transfer press and transfer press
A transfer press includes a press machine that moves a slide up and down in accordance with pressing motion, and a transport device that moves a retainer in accordance with transfer motion to transport a workpiece. The transfer press includes a creation unit, a determination unit, and a phase adjustment unit. The creation unit creates a three-dimensional operating curved surface based on the provisionally set pressing motion and the provisionally set transfer motion. The determination unit compares a standard upper die interference curved surface with the operating curved surface in the same three-dimensional coordinate system to determine whether the operating curved surface is present within an interference region of the standard upper die interference curved surface. The phase adjustment unit changes a relative phase of the transfer motion relative to the pressing motion when the operating curved surface is present within the interference region.
Press Installation and Control Method for a Press Installation
Control method for a press installation and installation, where the installation includes a servo press, a conveyor device for conveying pieces from a position of origin to the servo press, and a controller. The controller controls the movements of the conveyor device and of the servo press by means of one and the same master signal, causing a synchronized actuation of both. In the method, the pieces are conveyed to the position of origin and during the travel thereof until reaching the position of origin, the passage of the pieces through a predetermined position of reference before the position of origin is detected, and depending on the detection, the master signal is adjusted for adapting the actuation speed of the servo press.
