Abstract
This invention relates to the plastic metal working, particularly to tube rolling production and can be applied for tube cold pilgering on rolling machines. Tool design for tube cold pilgering, in which, in order to increase accuracy, surface quality, mechanical properties stability and decrease rolled tubes defects, the evolvement of external and profile of internal tooling are executed in the form of unified curve and represent geometrical location of various spline-functions key-points, whereupon along with geometrical parameters of spline-functions calculated curves the authors use factors defining physical-mathematical properties of rolled material and pilgering schemes.
