Abstract

"FERRAMENTAL PARA TRABALHAR ESTRUTURA PARA AUMENTAR A RESISTêNCIA à FADIGA EM UMA LOCALIZAçãO SELECIONADA NA MENCIONADA ESTRUTURA, MéTODO PARA TRABALHAR UMA PORçãO LIMìTROFE DE MATERIAL EM UMA ESTRUTURA, JUNTA, MéTODO PARA FABRICAR UMA JUNTA APARELHO PARA TRABALHAR A FRIO UMA PEçA DE TRABALHO, MéTODO PARA FABRICAR UMA PEçA DE TRABALHO PARA TER UMA ESTRUTURA COM MAIOR VIDA SEM FADIGA, PLACA METáLICA, MéTODO PARA FAZER UMA PARTE DE METAL ESPESSA, ARTIGO DE FABRICAçãO, E, PARTE ACABADA". Um entalhador composto (16) para trabalho a frio de metal, e um método de empregar tal ferramental. A ferramenta de entalhador composto (18) é usada para produzir deformação em uma estrutura de peça de trabalho (30) para prover um perfil de tensão residual benéfico selecionado na peça de trabalho (30), de modo a prover estruturas com longa vida sem fadiga em um número mínimo de etapas de fabricação. De preferência, a ação de um entalhador composto (18) causa deformação da peça de trabalho, causando pequenas covas na peça de trabalho. Uma forma aperfeiçoada de perfil de ferramenta de entalhador composto é descrita, tendo um primeiro entalhador alongado (20) com uma porção de supefície de entalhador modelada, e um segundo entalhador modelado (22) circundando o primeiro entalhador e formando um ombro anular (44) em recesso da porção de superfície do primeiro entalhador. Adicionalmente, uma base (60) tendo uma porção de fundo (80) pode ser usada para circundar de modo confinado o segundo entalhador para aplicação de força à superfície de uma peça de trabalho, para impedir deformação superficial.
