Systems engineering design and development of universal die set for hydraulic presses Purpose. Improvement of the universal die set (UDS) design for hydraulic presses based on system engineering and morphological synthesis of technical solutions. Methodology. System engineering methods were used in the development of the universal die set. This approach made it possible to formulate requirements and choose high-quality technical solutions. Stages of analysis and step-by-step design of nodes are identified and implemented. The stages of analysis and step-by-step design of nodes were identified and implemented. Classification of the types of connections of the construction elements of the UDS has been carried out. Contiguity matrices were constructed to describe the connections between elements of the UDS. This made it possible to formalize admissible combinations of node construction. The stages of the structure’s operation are defined using a state diagram for the stamping process. Different variants of the cycle of the press with varying ways of pushing the forgings out of the matrix are considered and given. Findings. A set of subsystems for UDS was developed, taking into account the expansion of the technological capabilities of hydraulic presses when implementing technologies with more complex kinematics than stamping processes that are usually used on hydraulic presses. The process of selecting UDS elements has been formalized. The expansion of the technological capabilities of universal hydraulic presses due to the adopted constructive decisions is shown. Originality. The design of the universal die set for hydraulic presses is based on the application of systems engineering methods is improved. The expansion of the technological capabilities of hydropresses was carried out on the basis of the proposed classification of the types of UDS structural elements connections and presses. Matrixes of permissible combinations of element connections have been developed for the selection of connections between the elements of the UDS construction. State diagrams have been developed for various options for the implementation of technological processes. Practical value. A methodology for applying systems engineering methods to the design of a UDS for hydraulic presses has been developed. It is shown that the application of system engineering methods allows for a guaranteed improvement of their technological capabilities. Based on this approach, the design of the UDS was developed to fit various work options. Using additional locking mechanisms to temporarily limit the mutual movement of the block and press elements allows the use of the main cylinder and the slave cylinder of the hydraulic press to perform various technological operations. This approach provides a more complex sequence of technological operations for manufacturing parts. An example of the application of the developed design of the UDS for the process of severe plastic deformation (SPD) by the method of reversible shear is presented.
