Despite the fact that stamping processes have been around for a relatively long time and have significant advantages compared to traditional approaches, as well as high technical and economic indicators, this process is not widespread.
The machine-building industry needs mass production and use of sophisticated parts of various designs. The need of Ukraine for the details of such a design varies significantly and can reach tens of millions of pieces. The need for ring blanks of type flanges (gear) of the total amount is more than 50% [1].
According to foreign enterprises, when cutting, the material utilization ratio is 40-50%, and when using stamping, it is pumped through using surface heating of workpieces - 75-80% [5]. If we take into account the use of energy for the production of steel and its processing per unit weight of the finished part, then it is 70–84 MJ / kg when machined, and 41–49 MJ / kg for plastic deformation.
To improve the ductility and deformability of the material, it is advisable to use induction plants for heating carbon steel preforms before pressure treatment. Two types of fundamentally different heating options are used: pass-through, when the workpiece warms up to its entire thickness with a temperature difference between the surface and the core of 50-100 °, and surface, when you need to heat only a relatively small layer of metal to a certain depth.
Before stamping, wetting requires the use of surface induction heating, which provides greater surface plasticity of the workpiece material without changing its structure [3]. In this regard, surface and end-to-end inductive heating installations are widely used in stamping processes for wetting.
The absence of theoretically justified parameters of the regime leads to the use in practice of induction heating of systems with unsuccessful design solutions and relatively low technical and economic indicators.
Thus, there is a need for relevant research aimed at determining the rational parameters of the heating mode, providing on this basis effective processing of workpieces.
