The role the rimming fixture is to ensure the models and the front cover having no relative motion in rolling process, and quality of fixture layout can influence if the cover edge has quality defects such as undulated in rimming process. First, this paper analyzes composition of the rimming bottom die and positioning clamping mechanism in rimming fixture, and obtains stressed situation of front cover edge under the action of rimming and stamping by the roll head by using the result of finite element analysis to the rimming process of front cover, combining with the design requirement of processing datum graph, the production program of engine hood, production class system and actuating rate „ÄĀfailure rate and production rhythm of production lines, establishes distribution points of rimming fixture and finally designs the rimming fixture of engine hood. The fixture is currently used in actual production with stable and reliable performance.
