Abstract

The article presents models of winding profiles from strips with different height-to-width ratios of the cross-section using a rotating cylindrical mandrel, along with a justification for the technological design of winding methods for screw and tubular profiles. The stress–strain state during winding is analyzed for plane strain and plane stress conditions under pure bending and bending by transverse force. Differences were established between the bending behavior of wide strips, narrow strips bent on edge, and intermediate profiles on a cylindrical mandrel. A generalized expression was derived to calculate the winding moments for profiles of different cross-sections.

It was demonstrated that when bending by a transverse force with a short lever arm, significant friction forces on the mandrel resist the compression of the inner layers of the workpiece, resulting in tensile stresses; thus, bending occurs due to a moment combined with longitudinal forces. Consequently, the total winding moment is higher than under pure bending, leading to greater energy consumption. At the same time, the radial load on the mandrel increases significantly, which negatively affects the durability of the technological equipment.

However, bending narrow strips on edge by a transverse force with a short lever arm improves the stability of the winding process and enables broader application of this technological method for the production of twisted profiles. This, in turn, expands the range of wound profiles, in particular screw spirals used in screw conveyors, mixers, and other technological equipment.
