Design of an Electromagnetic System to Avoid Horizontal Ram Displacement

Abstract:

Forming complex asymmetric parts lead to high horizontal process forces applied to the ram of a forming machine. These forces entail horizontal ram displacement and influence the quality of the finished parts negatively. By application of horizontal counterforces to the ram, the displacement could be avoided and the process stability could be improved. This paper presents a design of an electromagnetic system, which is capable to apply such high horizontal counterforces. To obtain high counterforces and a high dynamic simultaneously, the techniques premagnetisation and overexcitation have been tested numerically. Both mentioned techniques improve dynamic of electromagnetic systems by a large extent as illustrated in the paper.
