Theoretical Analysis of Machine Presses’ Untimely Unloading

Abstract:

Overload protection systems are commonly installed in machine presses for the protection of press and mould. If the setting of Pre-load pressure isn't correct, the overload system should take actions untimely, which deeply influences the productivity of machine presses. In this paper, a simplified model of the safety device is build and the reason causing the advance unloading is discussed in theory.
