Application of spring energy accumulators in forging and pressing equipment

Abstract

The development of forging and stamping production requires automation of various pressure treatment equipment. An important feature of the pressure treatment mechanisms is their inherent unsteady mode of operation, consisting of often alternating acceleration and deceleration, so the proportion of inertial loads is quite large. Such mechanisms are considered to be among the least efficient in terms of energy consumption parameters The low efficiency of the known designs is caused by the inability to exclude the influence of inertial forces on energy consumption and the speed of the equipment. The use of damping devices is not able to solve this problem, since they are designed to absorb a certain amount of energy and when the number of strokes per minute changes, they can cause an increase in dynamic loads.
