Forging tests of brackets with one and two ribs according to the new technology were realized in the three-slide
forging press in accordance with the schemas given in Fig. 2 and 3 [6]. The assumed semi-open die forming process
was based on upsetting of initial material in the form of a plate heated to the temperature t=410°C by means of two
side tools, which were heated to the temperature t= 200°C. In the result of reciprocal, horizontal movement of these
tools with constant velocity v= 6 mm/s, a rib was formed in the plate central part. Forgings with two ribs were
obtained applying the upper punch (Fig. 3).
