Parameters of the extraction of a thin-walled glass made of corrosion-resistant steel 12X18N10T

Abstract

Methods of metal processing by pressure are one of the most advanced technological methods of manufacturing thin-walled spatial parts. The volumetric stamping methods used ensure high productivity while maintaining product quality. Cold volumetric stamping is one of the main types of metal forming in many branches of mechanical engineering, as it most fully meets the requirements of approximating the shapes and sizes of workpieces to finished parts. Determining the rational technology of the stamping process is a fundamental factor in the development of the production of a new product. Hollow parts with a bottom of the "glass" type are usually obtained by direct or reverse extrusion. The maximum deformation and minimum wall thickness of the part in this case is determined depending on the technological deformability of the workpiece. The design of technological processes of cold volumetric stamping of thin-walled parts of the "glass" type involves solving a number of complex tasks: determination of the stress-strain state; determination of punching forces, loads, etc. The use of traditional methods of designing technological processes of cold volumetric stamping does not always allow us to solve these tasks and ensure the optimal combination of the required quality of the finished part and the minimum time and cost of production. One of the effective approaches to solving these problems is the use of computer-aided design systems based on computer technologies: CAD and SAE systems - software complexes for automated engineering analysis of volumetric stamping processes.
