Abstract

The frame of the precision punching machine is a supporting structure for other components, playing a crucial role in overall stability, accuracy, and lifespan. This article conducts finite element analysis and modal analysis on the frame, and optimizes the structure of the frame based on the analysis results, reducing the maximum stress of the welded side plate from 135MPa to 90.266MPa and significantly reducing the stress concentration coefficient. Modal analysis has determined the first four natural frequencies of the frame, providing a theoretical basis for avoiding fixed operating frequencies in precision punching machines.
