Combined shaping technologies based on cross-wedge rolling and stamping are proposed, which allow creating technological processes with a metal utilization factor of up to 0.98. The institute is looking for industrial partners or R&D organizations for commercial agreement with technical assistance, license agreement, or research cooperation agreement.
The combination of cross-wedge rolling (CWR) and stamping technologies makes it possible to create technological processes with a metal utilization factor of up to 0.98. CWR is used for the production of intermediate profiled blanks for subsequent precision stamping or other plastic shaping processes. The CWR method is used to manufacture parts of the type of bodies of revolution with an elongated axis, the shaping of which is carried out by redistributing the metal along the axis of the workpiece with a flat wedge tool moving across the axis. The configuration of the parts is very diverse: with cylindrical, conical and spheroidal surfaces with all kinds of grooves and protrusions. The resulting parts are characterized by high strength and wear resistance during operation.

An example is the developed and successfully applied technological process for producing track screws. The technology includes zone heating of a workpiece with a diameter of 24 mm and stamping of the screw head on a mechanical press, then a second zone heating and thread rolling with a diameter of 24 mm using the CWR method. The resulting products meet the requirements of GOST 809-71.

A number of resource-saving technologies for the manufacture of various parts have been developed, including the operation of pre-preparation CWR and subsequent flashless stamping from the same heating. For example, the technology for obtaining a wrench consists of two stages: automatic production of a preliminary workpiece from a bar stock using the CWR method and stamping on a hammer or press.

Areas of application - the production of parts in the automotive industry, machine tool building, instrument making, agricultural engineering, tractor building, aircraft building, motorbike building, mining and nuclear industries.

Almost all structural steels are processed, as well as brass, titanium, zirconium and nickel alloys.
Advantages and Innovations
The combination of CWR and stamping technologies makes it possible to obtain maximum savings in material and energy resources with the creation of high-quality parts in the forging and stamping industry.

Competitive advantages:
•reduction of metal consumption rate by 30–60%;
• increase in labor productivity;
•high precision and surface finish of products;
•improvement of performance characteristics of the resulting products by 20-30%;
• tool life until its complete failure is 1 million items;
• exclusion or minimization of the final finishing of products;
• reduction of energy consumption of the process.

The novelty of the development lies in the optimal combination of classical technologies to obtain high-quality products with maximum savings in material and energy resources.
