Objective of investigation: improvement of quality, the accuracy of products on the basis of improvement of the equipment and technological processes with the combined loading of preparations when processing by pressure. Methods of investigation: theoretical researches on mathematical models on the basis of provisions of mechanics of firm environments, the theory of reliability, design methods, etc., pilot studies on laboratory installations. Theoretical and practical results: 1 By means of experiment possibility of use in hydraulic systems of working tools with barrel-shaped and spherical surfaces and slot-hole consolidations is proved. 2 Operability of BS with an adjustable condensed crack by giving of pressure of management on the surface opposite by the operated is confirmed. 3 The size of gaps in a condensed crack depending on their geometrical parameters, a sort and liquid pressure is established. 4 Possibility of effective application of consolidations for a sphere or a barrel-shaped body is confirmed. 5 Mathematically firmness of the instrument of friction for a tangential running in of tubular preparations, linear wear on the tool is distributed is unevenly predicted. 6 Tools greatest wear and are maximum a tolerance of the geometrical sizes of the tool is defined. 7 Size of temperature gradients which influences a pressing cycle, a tool design, a form, the sizes and properties of a material of pressed products it is defined. Novelty: 1 Experimental installation in hydraulic systems of working tools with barrel-shaped and spherical surfaces and slot-hole consolidations is developed for research of possibility of use. 2 System of regulation of size of leaks through BS is developed by change of pressure of management. 3 Experimental installation for a sphere or a barrel-shaped body is developed for research of possibility of effective application of consolidations. 4 Mathematical model allowing to predict firmness of the instrument of friction for a tangential running in of tubular preparations, linear wear on the tool is distributed is unevenly developed. 5 Modeling of hot pressing of powder materials new away with heating by pulsing electric current it is developed. 6 new control system of a forming hammer with use of valvate distributing devices is developed.
