Abstract:

　This press brake is provided at the lower part of left and right side frames (5L, 5R) with a lower table (9), and at the upper part of the side frames (5L, 5R) with an upper table (7) facing the lower table (9), either the upper table (7) or the lower table (9) being vertically moveable by way of a ram; and provided at both of the side frames (5L, 5R) with left and right vertical driving means (11L, 11R) for vertically moving the ram. At both the inside surface and the outside surface of the left and right side frames (5L, 5R), strain detection sensors (15A, 15B, 15C, 15D) are provided for detecting strain of the side frames (5L, 5R), whereby deflection in the vertical direction can be detected while canceling deflection of the side frames towards the lateral direction.
