Effective Tooling Designs for Production of Precision Forgings.
Abstract
The aim of the two-phase program is to demonstrate that nonsymmetric rib-and-web type configurations can be hot forged to precision dimensions with better die life through the use of reinforcing components surrounding the die inserts. Efforts consisted of (1) a review of the literature on precision forging where die breakage has been a problem, (2) visits to five leading forging companies active in precision forging and companies active in Government-sponsored research on forging, (3) selection of a part configuraiton for design, (4) analytical modeling studies of stress distribution in the die assembly, (5) developing the preform design through the use of Plasticine and hard plastic dies, (6) conducting forging trials in model dies instrumented with strain gages, and (7) conducting hot forging trials on aluminum, AISI 4340 steel, and Inconel 718 alloys in Battelle's 2500-ton press.
