Abstract
The press frame vibrations of a stamping press due to the high number of strokes, as well as the vibrations of the ram caused by the cutting impact have a great influence on the economy of a blanking process. The following contribution presents the state of the art regarding the compensation of these and explains the disadvantages of the existent solutions briefly. Based on this overview, two methods are presented to overcome the disadvantages. The first method introduces the vibration compensation of a press body by means of an auto-adaptive mass balancing system. Consisting of four linear motors this system does not increase the inertial forces of the drive train. This is particularly interesting for servo presses. The second method is the compensation of the ram vibrations by using additional forming operations in chad area. This approach enables tool wear reduction with very low investment costs compared to a machine-side solution.
