The analysis of the impact of technological processes of hot forging on the dynamics of the crank press

Physical modeling low-waste technological process of the round forging hot stamp

“…The theory of the methodology for calculating the protrusion geometric parameters is described in [6,7]. This article presents the methodology and results of experimental confirmation of the possibility of using HDF technological schemes with the protrusion in practice.…”

“…Reducing the coefficient of metal consumption of the technological process of hot die forging (HDF) while minimizing the technological force of stamping is the most important indicator of its efficiency [1,2,3]. The HDF technological processes that make it possible to implement this efficiency condition are known from [4,5,6]. Their peculiarity lies in the formation of a protrusion (R1) of the certain shape at the preliminary transition [6], with the deformation of which, at the final transition, filling of the stamp engraving begins.…”

“…The HDF technological processes that make it possible to implement this efficiency condition are known from [4,5,6]. Their peculiarity lies in the formation of a protrusion (R1) of the certain shape at the preliminary transition [6], with the deformation of which, at the final transition, filling of the stamp engraving begins. The result is an outer stamping radius R2 with minimum dimensions (Figure 1).…”
