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.

Highlights

For the manufacture of articles with high reliability and durability during hot forging are standing problems performing the necessary treatment of the metal structure throughout the volume of the product or parts of the volume by plastic deformation

Summary

Introduction

For the manufacture of articles with high reliability and durability during hot forging are standing problems performing the necessary treatment of the metal structure throughout the volume of the product or parts of the volume by plastic deformation. In the sources [7,8,9] are given the possibility of obtaining by forging and hot stamping the responsible products from steels with the treatment of the structure of the metal by plastic deformation and the achievement of the necessary distribution of deformations in the bulk of products The authors of these studies have shown that the treatment of structure can be evaluated from the finite distribution of the strain intensity in the deformed workpieces. Purpose of this work is to define the parameters and development of technology of hot forming of hollow articles made of high-strength aluminum alloy V93pch with a given treatment of the metal structure for all height of the wall by plastic deformation
