Abstract
An analytical method is proposed for calculating the shaping parameters of thick sheet in the production of large-diameter pipe. This method is considered in several stages: formulation of a geometric model of the blank and the tool; numerical calculations; selection of the algorithm; and analysis of the results. Comparison of calculated and experimental shaping parameters for sheet used in the production of different types of large-diameter pipe reveals good agreement. The proposed method is recommended for calculating the shaping parameters in the production of large-diameter pipe and the setup so as to minimize the defects due to the geometry of the press.
