The bending machine (10) that is the subject of the invention has an upper jaw (20) and a lower jaw (30). At least one side wall (40) provided on each side of the bending machine (10) There are. The lower jaw (30) and upper jaw (20) lateral walls (40) mentioned are 25 It lies between them. The aforementioned side wall (40) is provided in the form of a flat plate. The side wall There is a central drain (43) provided in the form of an opening on (40). Central The discharge (43) starts from one of the upper edges of the side wall (40) and goes down 30 (44). It is partially extended. Middle discharge (43) lower jaw (30) and upper jaw (20) This is provided at the intersection of the plane on which it is located and the side wall (40). 4 There is a drive element (50) located inside the middle discharge (43). The drive element (50) is a hydraulic or pneumatic cylinder in a possible configuration. The mentioned drive element (50) has a drive lever (51). The aforementioned drive lever (51) moves along a drive axis (a). Drive lever (51) is also connected to the upper jaw (20). The drive element (50) drive 5 By pushing his arm (51), the upper jaw (20) can move closer to and further away from the lower jaw (30). The drive element (50) must be held in place within the middle discharge (43). There is at least one connecting plate (60) to provide the aforementioned connection. plate (60) is provided in multiple numbers in a possible configuration and the side wall 10 (40) connects to the drive element (50) from both sides to fix it. In the mentioned configuration, the axis of movement of the drive lever (51) is also the lateral axis. the intersection of the plane on which the wall (40) extends and the plane on which the upper jaw (20) extends It coincides with the line. In other words, the upper jaw (20) coincides with the line where the upper jaw (20) extends. Drive at the intersection line of the plane with the plane on which the side wall (40) extends Therefore, the drive axis (a) to which the driving force is applied and the lateral Since the plane of the wall (40) coincides, there is a bending force on the side wall (40).
