The cold drawing process takes places very quickly and during the conversion of mechanical energy into the heat energy the work peace and the tool heat up considerably. In order to achieve a stabile drawing process, it is necessary to keep tracks of the temperature growth of the work piece and the tool. The tool temperature has to be below the established limits, and it is regulated by the amount of the coolant, which is at the same time also a lubricant. The expressions for the temperature growth calculation in the conditions of adiabatic processes that can also be applied to the deep drawing process with the reduction of the wall thickness, due to the high deformation rate, have been presented in the work. The heat balance equation enables the determination of the coolant mass which will maintain the stabile tool temperature, what is confirmed by the experimental researches.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
