<p>A system for working on a plate material, including a back gauge device (41) having a mold changing function and a function of positioning the plate material in the longitudinal direction thereof. In the system (1) for working on the plate material, comprising a top table (5) and a bottom table (7), which are supported on right and left side frames (3L, 3R), either one of the top table (5) and the bottom table (7) serving as a ram which can vertically move, molds (17, 19) for working on the plate material (W) in a working region between the top table (5) and the bottom table (7), and a back gauge device (41) for positioning the longitudinal direction of the plate material (W) to be worked on by the molds (17, 19) so that said back gauge (41) is movable in the longitudinal direction thereof, a mold housing portion (37) is provided in the rear region of the top table (5) and a part of the back gauge device (41) can move vertically and support the molds (17, 19), so that the molds (17, 19) can be changed in a space formed between the mold housing portion (37) and the aforesaid working region. <IMAGE></p> |
