Abstract

The classical manufacture technology of H68 brass cylindrical shell part with deep blind hole is machining process, which can achieve requirements of dimension precision, but the process has lower efficiency, and the strength and toughness of the parts do not satisfy the usage requirements in the industry. The multi-stage cold forging process, which could improve the mechanical properties of the parts, is used to replace the traditional machining process. The process designs of multi-stage cold forging process for parts have been studied, including several operations such as annealing, initial upsetting, preforming, back extrusion, ironing, and upsetting flange. In order to ensure the multi-stage cold forging process, one finite element (FE) simulation, used to study strain distributions and flow lines, is conducted. Based on the FE results, several cold forging dies have been designed and manufactured. The experimental work shows that the cold work-hardening effect is obtained, and distribution of flow lines is reasonable; precision accuracy and mechanical properties meet the technical requirements, and production efficiency has been improved significantly.
