Abstract

One of the methods for increasing the quality of the reconfigurable multipoint formed parts is to use an elastic interpolator between the pins active elements and the blank. The paper presents a numerical model based on the study of the rigid/elastic-plastic medium assembly behavior toward its application to the design of the new controllable multipoint dies with flexible interface. In the first part of the paper, general aspects of material behavior laws are dealt with in reconfigurable multipoint forming system. Then, in the paper proper are presented the simulations results, using finite element approach, regarding the influence of the interpolator thickness and pins penetration toward the parts quality. The parts quality is evaluated in terms of springback and stresses state variation. The results could lead to the development of these new types of equipments which assure the decreasing of the cost testing and production.
