Overload protection for spindle presses by a limitation of the torque introduced into the spindle, the spindle nut being mounted rotatably

摘要

The invention relates to an overload protection for spindle presses by a limitation of the torque introduced into the spindle, the spindle nut being mounted rotatably, and its set object is to improve such an overload protection in comparison with conventional versions. This is achieved, on the one hand, in that the spindle nut (6), when arranged in the press ram, is supported on the latter via interposed hydraulic piston/cylinder units (8, 9) or resilient elements. But it is also possible for the spindle nut (6), when arranged in the press body, to be supported on the latter via interposed hydraulic piston/cylinder units (8, 9) or resilient elements. IMAGE
