Further Development of a Hydraulically Operated Oscillation Device for Application to an Industrial Forming Process

A superimposed oscillation in the main force flow of a forming process is investigated. Therefore a tool system was developed. The oscillation in this system is generated by pulsating oil streams. As part of this research, the oscillation device is equipped with additional storage tanks, to generate a higher oil volume flow. The upgraded oscillation system is installed in a forming process. In this research, the influence of the superimposed oscillation on the necessary plastic work to form a complex gear geometry is examined. An analysis of the influence of higher forming forces, higher operating pressures and longer process times on the operating behavior of the oscillating device also takes place. The identified optimal process parameters are used in a model process based on the industrial forming process of the company Felss Systems GmbH. Furthermore, an experimental test setup to carry out these investigations is developed in this research. Forming experiments to iron an external gear geometry oscillation-free and superimposed oscillated are conducted with the new test stand.
