摘要

Mechanical presses utilizing multi-link systems play a pivotal role in applications such as deep drawing, forming, and blanking. In the design of these multi-link transmission mechanisms, generating a diverse range of feasible mechanisms is crucial. This paper introduces a novel configuration synthesis method, leveraging compound joint transformations, for designing 1-degree-of-freedom (1-DOF) multi-link mechanisms. Initially, the study involves a thorough analysis of various characteristics inherent to multi-link mechanical press transmission systems. Subsequently, it establishes the constraints and design requirements for the transmission mechanism. The method utilizes the concept of a compound joints factor to execute a transformation of the initial mechanism. An improved joint structure matrix (IJSM) is employed to identify and eliminate redundant sub-chains and isomorphisms in the resultant mechanisms. This research integrates all potential configurations of 6–10 link multi-link mechanisms tailored for mechanical presses, expanding the horizons of mechanical press design.
