自由锻多工步全流程自动化模拟系统OA

To meet the requirements of"high performance,high precision,and long life"for disc-shaped forgings such as flanges in light industrial equipment,promote the evolution of forging technology to digitalization and greening,and solve the problems of inefficiency in Computer Aided Process Planning(CAPP)validation for open die forging of disc forgings and the cumbersome multi-step simulation process in the finite element simulation software DEFORM,the research group developed a fully automated simulation system.The system intelligently parses process card texts with regular expressions to extract parameters,and uses the open-source 3D finite element mesh generator GMSH library to perform parametric modeling and meshing of blanks and tooling.Based on the programmatic configuration of the KEY file keywords of the DEFORM software and combined with its text mode,the unattended operation of multi-step simulation was realized.The results of actual case simulation demonstrate that the system effectively prevents internal defects in forgings,reduces traditional manual setup time from several hours to minutes,controls average dimensional errors of forgings within 0.5%,and provides an efficient solution for the digitization of free forging processes.
