Annotation

The article conducted a study of calculation methods and the selection of technological parameters for stamping by rolling in complex profile products. It is shown that the achievement of significant sizes of various elements of the workpiece is possible by ensuring the directional flow of metal by changing the relative positions of the roll and the workpiece. The most effective rolling stamping operations are upsetting, deposition and backward extrusion. The zones of workpieces that are deformed under stress conditions have been identified, therefore, to determine the technological capabilities for them, an assessment of the deformation of metals should be carried out. The manufacture of thin-walled elements of the workpiece using the operation of backward extrusion is accompanied by the appearance of significant contact stresses, therefore, to prevent the roll from being removed from the workpiece, back-up rollers should be provided.
The analysis of the study showed that the stamping process by rolling over the workpieces with conical and cylindrical rolls makes it possible to control the flow direction of the workpiece material by changing the size and direction of the relative position of the axes of the workpiece roll, relative to the direction of rotation of the workpiece. The technological capabilities of SHO are limited mainly by the loss of stability and destruction of the workpieces, which, in turn, substantially depends on the direction of the metal flow in the contact of the roll with the workpiece.
The modeling of the SHO process is considered. It has shown that the stress-strain state, the shape change and the deformability of the workpiece material substantially depend on these parameters.
The purpose of the simulation was to analyze the stress-strain (VAT) state and shape change of the workpieces during the deformation process, to determine the energy-power parameters of the process, as well as the geometry of the deforming tool, providing a high-quality product with guaranteed profile filling, accurate dimensions in the transverse and longitudinal directions, as well as surface cleanliness profiled cavity.

Keywords: rolling stamping, metal forming, technological process, stress-strain state of computer modeling, complex products, plastic deformation.
