Abstract

APARELHO PARA ESPESSAMENTO, PROCESSO DE ESPESSAMENTO DE PORÇÕES DE BORDA EM UMA SUPERFÍCIE INTERNA DE UM TUBO E TUBO. Um aparelho para espessamento de porções de borda em uma superfície interna de um tubo é divulgado. O aparelho inclui um primeiro membro de suporte, que é configurado para suportar rigidamente uma superfície externa ao longo de seu comprimento. O aparelho inclui ainda um segundo membro de suporte configurado para suportar rigidamente a superfície interna do tubo ao longo de seu comprimento excluindo a porção de borda na superfície interna do tubo. O segundo membro é um mandril de múltiplas peças. O aparelho também inclui um punção acionado por uma fonte de potência externa, em que o punção é configurado para exercer força simultaneamente nas porções de borda do tubo. A aplicação de força pelo punção nas porções de borda do tubo deforma plasticamente a porção de borda do tubo para se conformar a um formato do segundo membro de suporte em ambas as extremidades para espessar as porções de borda na superfície interna do tubo.APPLIANCE FOR THICKENING, PROCESS OF THICKENING EDGE PORTIONS ON AN INNER SURFACE OF A TUBE AND TUBE. An apparatus for thickening edge portions on an inner surface of a tube is disclosed. The apparatus includes a first support member which is configured to rigidly support an outer surface along its length. The apparatus further includes a second support member configured to rigidly support the inner surface of the tube along its length excluding the edge portion on the inner surface of the tube. The second member is a multi-piece chuck. The apparatus also includes a punch driven by an external power source, wherein the punch is configured to exert force simultaneously on the edge portions of the tube. The application of force by the punch to the edge portions of the tube plastically deforms the edge portion of the tube to conform to a shape of the second support member at both ends to thicken the edge portions on the inner surface of the tube.
