Abstract

Hydraulic deep drawing presses are manifold machines that can be used for a number of use cases. The general need for the reduction of the energy consumption of industrial machines forces press manufacturers and owners to optimize their machines and processes. This article presents methods for the analysis and optimization of the drive systems of a hydraulic deep drawing press with four-point die cushion. For the slide drive, two alternatives of control methods for speed variable displacement pumps are compared to the conventionally used displacement pump with a constant speed. For the drive of the die cushion, two displacement control drive systems are compared to a conventional valve drive system.
