Abstract:Punching machine driven by linear motor can achieve "zero drive", which has the advantages of simple structure, high control precision and low noise, so it is one important development direction of precision punching machine. Based on the design of punching machine structure driven by linear motor, dynamics simulation analysis for the simplified punching machine work process was carried out by using the ADAMS software, and then moving parts’ displacement time, speed time, acceleration time and press forcetime curves were obtained. All these results were consistent with the design requirements. The punch direct carrying member mold stiffness was analyzed by using HyperMesh finite element analysis software. Through the analysis, the designed mold structure can meet the requirements of stiffness. The punching machine control system was designed as well.
