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 tool21and a lower tool22are provided which fix a plate material W by sandwiching it between themselves. An upper tool-side bending tool23and a lower tool-side bending tool24are provided on sides of the upper tool21and lower tool22, respectively, so as to elevate and lower freely. The upper tool-side bending tool23and the lower tool-side bending tool24perform elevating and lowering operations relative to the upper tool21and the lower tool22to bend a plate material piece Wa of a plate material W sandwiched between the upper tool21and the lower tool22. A plate material feeding mechanism adjusts the length over which the plate material piece Wa projects from the upper tool21and lower tool22.
