Abstract

Using the finite element method conducted research of technology and established parameters of hot forming hollow products of alloy V93pch with required treatment of metal structure by plastic deformation to provide the mechanical properties in the wall of product after heat treatment. There are determined by the calculation the shape and dimensions of the initial workpiece, temperature heating deforming die, forming’s force, force of pushing the product from matrix, the specific forces on the deforming die, temperature change during forming of the product, stress-strain state in deformed metal, final shape and size of the product. According to the results of modeling designed and manufactured stamp for hot forming and conducted experimental research in a hydraulic press. Submitted stretching’s tests of standard samples, that were cut from the wall of the product after the heat treatment. Defined conditional yield strength, strength limit, conditional elongation and hardness. The test data meet the requirements for the mechanical properties of deformed metal in the wall of the product.
