Annotation

Reducing the power of forging and pressing equipment is an important task of modern metal forming technologies. The article is devoted to the development and research of dies capable of significantly (tens or more times) reducing the power of the used forging and pressing equipment due to the use of energy-saving dies that can significantly increase the deforming force. A stamp capable of significantly increasing the deforming force is called energy-saving . The article shows that using different types of levers, it becomes possible to significantly increase the useful force of stamping tools acting on a deformable workpiece. Thus, it becomes possible to use relatively low-power pressing equipment to achieve significant forces of the working tool. Based on the given mathematical dependences of the geometric and power characteristics of the energy-saving stamp, a computer program was developed in MS Excel and modeling was carried out, with the help of which it was studied how the deforming force R changes depending on the change in the angle of inclination of the punches  and the corresponding graph was plotted at a predetermined constant pushing force F = 1 N.  After analyzing the resulting graph, it can be argued that a tenfold increase in the deforming force R compared to the pushing force F, which is created by the pressing equipment, is observed at an angle of  = 5.35 degrees, fifty times at an angle of 1.1 degrees. At angles approaching 0 degrees, the increase in the deforming force can reach significant values and is limited only by the strength of the energy-saving stamp itself. Calculation formulas are given that allow calculating the main dimensions of the punches and the working stroke of the forging and pressing equipment for a given working stroke of the punches and a given increase in the deforming force. Possible areas of application of the energy- saving stamp are shown.

Keywords: radial reduction, energy- saving die, increase in deformation force.
