Research the Impulse Stamping Technology of High-Strength Hard-to-Form Alloys

Abstract

This article is devoted to expanding the technological capabilities of the gas-forming stamping method by increasing the pressure of combustion products acting on the surface of a workpiece stamped. Therefore, a scheme of a two-chamber device and a method for compressing the fuel mixture is proposed. The essence of the method is that of carrying out the stamping products under the high gas pressure, which is created by compression and subsequent combustion of the gaseous fuel mixture. To ensure the compression of the fuel mixture, the device is equipped with two combustion chambers separated by a piston. Due to this method, the pressure rises sharply. Under the influence of the combustion products' pressure, the workpiece is intensely deformed and fills the cavity of the matrix. This method of sheet stamping, implemented on a two-chamber device, will increase the gas pressure on the surface of the forged workpiece to 70-80 MPa at a fuel mixture pressure of 1 MPa, which ensures stamping of a variety range of parts in almost all branches of small-scale production related to metalworking.
