Abstract


This article deals with the design of a new crank forging press. Forging press has to respond to higher number of customer requirements. Most of them can be divided into two categories – technological requirements and economic requirements. Technological requirements include forging of new materials which are less formable and forging of larger parts. Economic requirements are focused on dimension stability and the minimizing of the additional machining. The design of new machine must respond adequately to all requirements. Some requirements are in conflict. Several design changes are presented in the article. These changes are analyzed and their benefits described. Main design changes are focused on workspace, bearings and cranks. Virtual simulation of behaviour during forging process was used for the evaluation.
