Abstract

The invention discloses a preparation method of a variable cross-section revolved body shaped charge liner. The preparation method comprises the following steps: primary heating: heating a blank and preheating a mold; primary die forging is conducted, specifically, the heated blank is taken out of the heat treatment furnace and placed into a lower die to be positioned; secondary heating: taking out the blank, cooling to room temperature, and heating again; secondary die forging is carried out, specifically, the alloy subjected to heat treatment is put into a die, and positioning and deformation are carried out; annealing: taking out the blank, performing recrystallization annealing, and then cooling to room temperature; and post-treatment is conducted, specifically, the annealed blank is subjected to finish machining, and the revolved body shaped charge liner is manufactured. Compared with the prior art, the production efficiency and the material utilization rate are both achieved.
