STUDYING THE BACK-EXTRACTIONPROCESS
Processing of metals by pressure is represented by a wide range of operations and methods of shaping, with each operation corresponding to a specific set offorging and stamping equipment. Each of the machines for carrying out forming operations has its own key features and it is not always possible to use different operations on the same equipment. Therefore, this paper provides a classification of forging and stamping equipment, describes the functionality. The design features of some machines are described. With the help of computer simulation, the process of reverse hot extrusion of a steel billet with a flange and a vertical wall is studied. The forms of the obtained products obtained from the results of computer simulation in the finite element analysis program are given. The paper presents graphs of the technological effort of stamping a semi-finished product made using different shape-changing tools. Conclusions are drawn about the possibility of using such a method and a tool for stamping the required part.
