Abstract：

After analyzing the hemming technology of trunk lid, a hemming process including robots loading, manual unloading, sub-regional pre-bending, circumferential casting pressing blank and pressing and the structural design of hemming die for trunk lid were introduced. The purposes of good pre-bending and pressing for hemming were realized. Meanwhile the smooth line after hemming, uniform overlap gap of various parts, consistency of surface quality and surface quality of hemming board piece were guaranteed. The structure of trunk lid hemming die，hemming structure and principle, pressing core structure and design characteristics of lift transport mechanism, working principle and motion simulation were focused on．The production proves that the trunk lid hemming technology and die structure design can reduce die development costs and enhance quality in product appearance and production efficiency.
