Abstract
In a bending press, the stroke length of a ram member is automatically set based upon conditions such as the angle to be made on a workpiece, the width and configuration of a groove in a lower tool, and the thickness, width and tensile strength of the workpiece. There is also an input device into which the bending conditions are set and a computer for calculating the stroke length of the ram member which is then automatically adjusted. A device for detecting deflections occurring in an overhead beam in the bending press is connected to the computer to compensate for the stroke lengths of the ram member. The press accurately and easily bends sheet-like workpieces into various shapes including those cylindrical and semicircular in cross section.
