Abstract

Abstract: In order to solve the problems of car creep or roll-in and grow or roll-out and wave wrinkling defects in the process of sunroof roller hemming, two quantitative indicators of roller hemming—“coefficient of wave wrinkling” T and “coefficient of creep or roll-in and grow or roll-out” D were put forward in terms of the flange height, roll diameter and distance of TCP-RTP (tool center point-robot target point); a simulation experiment was designed based on orthogonal test; and a finite element model was established. By analyzing the simulation experiment data, the weights and trends of the influence factors on the two indicators as well as the main factor of the two indicators were obtained.

Key words: roller hemming, process parameters, quantitative indicators, orthogonal test
