Optimization on Deep Drawing and Ironing Process of Compressed Natural Gas Containers

Abstract:

In this article, the influence of different process parameters on the bottom thickness of CNG container during the deep drawing and ironing process has been analyzed by simulation. The bottom die fillet R, the spacer height H between blank holder and bottom die and the friction coefficient μ between punch and billet were selected as parameters for optimization. The simulation results reveals that the appropriate bottom die fillet R and spacer height H is needed to reduce the thinning of product bottom. Meanwhile, the bigger the friction coefficient μ, the thicker the product bottom. The optimized results were utilized in the experimental production and the products in the three passes meet the designed requirements, which illustrates that the simulation results have great help for the actual production.
