摘要： This invention relates to a method and apparatus for adjusting a stroke length of a ram for a press. The stroke length of the ram is adjusted with respect to a base point. The hydraulic pressure level in the acting chanber is also adjusted. The press is generally used for bending metal sheets. By this invention, an optimum stroke length of the ram in the press can be easily determined without experimentally processing and, therefore, wasting sheet metal workpieces.
摘要翻译：本发明涉及一种用于调节冲压机冲头行程长度的方法和装置。冲头的行程长度相对于基点进行调整。也可以调节作用通道中的液压水平。压机通常用于弯曲金属板。通过本发明，可以容易地确定压机中的冲头的最佳行程长度，而不进行实验处理，因此浪费金属板材。

摘要： 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.
摘要翻译：在弯曲压力机中，冲头构件的行程长度根据诸如在工件上形成的角度，下部工具中的槽的宽度和形状以及厚度，宽度和拉伸强度等条件自动设定工件。还有一个输入装置，弯曲条件被设置到其中，计算机用于计算冲头部件的行程长度，然后自动调整。用于检测在弯曲压力机中的顶部梁中发生的挠曲的装置连接到计算机以补偿冲头构件的行程长度。压力机准确且容易地将片状工件弯曲成各种形状，包括圆形和半圆形的横截面。
