Study on the Processing Rate Allocation in Forming Process of Cartridge Case

Abstract

With the development of die industry, multi-position progressive die is used wildly. The process rate allocation of each punching process is very important during the whole cartridge case forming. This paper shows a key point to the theoretical calculation of process rate allocation of cutting cupping, first cite-longing and second cite-longing, and these theoretical formulas can provide a reference for future researchers.
