A resonable stamping process,layout diagrams and structure of mold were designed for the pendulum with small size ,high-volume and high requirements for size and position tolerance. The parts were analyzed that the stripping materials might be tortured ,the dimensional accuracy of(9.3 ± 0.15)mm,(22.5±0.1)mm,(1.5±0.1)mm could not be guaranteed for springback,and the jump-crumbs would be occured when stamping incoming stock hole.Then the corresponding solutions were found. The production practical shows that the stamping process,layout diagrams and mold structure design are reasonable and the qualified parts are obtained.
