Abstract

"APARELHO PARA EXECUTAR OPERAçãO DEHIDROFORMAçãO". Um aparelho de hidroformação é capaz dedeformar peças de trabalho relativamente grandes e de paredegrossa, embora ainda seja relativamente pequeno, simples e baratona construção e operação. O aparelho de hidroformação incluiuma mesa superior e uma mesa inferior que são ligadas juntas portirantes que se estendem através de tubos de compressãorespectivos. Uma seção de matriz superior é apoiada na mesasuperior, enquanto uma seção de matriz inferior é apoiada na mesainferior para movimento vertical em relação à seção de matrizsuperior. As seções de matriz superior e inferior têm áreas recuadasrespectivas formadas nas mesmas que definem uma cavidade dematriz de hidroformação. Quando a seção de matriz inferior émovida para uma posição abaixada, uma peça de trabalho podeser disposta na área recuada formada na mesma. Então, a seçãode matriz inferior e a peça de trabalho são elevadas por cilindros,de modo que a peça de trabalho seja encerrada dentro dacavidade de hidroformação e mecanicamente deformada pelasseções de matriz superior e inferior em cooperação. Um bloco desuporte de hidroformação é, então, movido entre a matriz dehidroformação e a mesa inferior. Um conjunto de cilindro contendouma pluralidade de pistões é a seguir hidraulicamente acionado, demodo a fixar de modo fixo a matriz de hidroformação entre oconjunto de cilindro e a mesa inferior. Enquanto o conjunto decilindro é acionado, fluido pressurizado é fornecido dentro da peçade trabalho fazendo a mesma se deformar em conformidade com acavidade da matriz de hidroformação.
