The System of Informational Choice of the Kinematic Scheme for the Formation of Shells of a Complex Spatial Form

Abstract

Three kinematic schemes are studied, which differ from one another in the route of technological operations. Each of these kinematic schemes has its own set of power stages of shaping and stages of free bending or bending of the ends of the sheet blank. In addition, the quantitative values of the angular parameters of a particular kinematic scheme are determined. Numerical experiments have been carried out, which give complete information about the distribution of the shell thickness as discrete values in one or another element. The result is statistical processing of this information, the scope of the predicted values and comparison with the tolerance on the thickness of the peel used in aviation enterprises.

Influence of the Sheet Metal Anisotropy on Polythickness of the Skin after Stretch Forming

“…This scheme of stretch forming can be implemented on the press equipped with the automation system, for example on FEKD press (Fig. 1), due to the simultaneous movement of the left and right balancing arms with gripping jaws and mounted on press bed stretching punch [9][10].…”
