Parameter estimation of thick-walled tube forming pieces crimped conical matrices in the absence of radial deformation of the inner surface of not crimped portion of workpiece
In the article the results of research of thick-walled tube billet forming matrices with conical funnel in 150, 200 and 250 and crimping from 1,2 to 1,5 for the schema when in the not crimped portion of workpiece is placed mandrel to remove the possibility of metal flow in this zone in the direction of the axis of a workpiece. Quantitative data can help you to simulate the shape and size of forgings with specified initial workpiece and tool options.
