Abstract: In order to study the secondary deep drawing forming theory, the tensile stress theoretical model of secondary deep drawing is proposed. First, by theoretical analysis, the calculation formula of tensile stress is deduced, and the calculation method of the limited secondary deep drawing coefficient is established based on the Swift instability theory. Second, the accuracy of the calculation model is examined by secondary deep drawing simulation, and the applicability of the calculation model is verified by means of successful secondary deep drawing forming experiment. The results show that the theoretical model of the tensile stress and the limited secondary deep drawing coefficient has high precision.

Key words: machinery manufacturing technology and equipment, secondary deep drawing, tensile stress, deep drawing coefficient
