Abstract

The simulation of several variants of rolling of drawers from the model material of aluminum alloy AL-1100 and bearing steel ШХ-15 using the software package Deform 3D. Helical-shaped rollers were used as the profiling elements for receiving balls. The influence of various parameters on the stress-strain state of roll elements and workpieces is investigated. It is shown that the process qualitatively occurs without lubrication at high coefficient of friction up to 0.4 The contact stresses on the surface of the rolls reach significant values, which leads to the need for additional surface treatment by surface hardening methods. The technology and construction of rollers for cylindrical billets are offered.
