Abstract
The technological process of hot stamping of high-strength nuts has been developed and investigated using digital modeling. The scheme of the technological process and the punching force, the dimensions of the workpiece are determined, the stress-strain state and temperature of the metal in terms of forging volume along the stamping transitions are investigated when using a conventional billet draft before stamping and a special draft with the formation of a conical part on the billet. Based on the analysis of the results of digital modeling of the technological process of hot stamping, it was found that the following technological process of hot stamping is recommended for the production of cap nuts: cutting and heating the workpieces to the temperature of hot stamping, a special deposit with the formation of an entrance cone with an angle of 25 ° on the workpiece, hot stamping of the nut in one transition. The use of the proposed technological process makes it possible to obtain the forging of the cap nut with subsequent minimal machining. Based on the results of process modeling, technological equipment for hot stamping of the cap nut is proposed. The results obtained can be used in practice.
