Abstract
The present invention provides a plate material processing machine with a bending function which enables even a bending piece with two or more bending portions to be bent and which enables materials to be bend so as to have different bending directions, dimensions, angles, or the like using the same tools. An upper tooland a lower toolare provided which fix a plate material W by sandwiching it between themselves. An upper tool-side bending tooland a lower tool-side bending toolare provided on sides of the upper tooland lower tool, respectively, so as to elevate and lower freely. The upper tool-side bending tooland the lower tool-side bending toolperform elevating and lowering operations relative to the upper tooland the lower toolto bend a plate material piece Wa of a plate material W sandwiched between the upper tooland the lower tool. A plate material feeding mechanism adjusts the length over which the plate material piece Wa projects from the upper tooland lower tool
