Abstract

La presente divulgación se refiere a un aparato para engrosar un tubo en su porción intermedia a lo largo de una superficie interior. El aparato incluye un primer miembro de soporte para soportar la superficie exterior del tubo y un conjunto de mandril para soportar la superficie interior del tubo, donde el conjunto de mandril está soportado por un segundo miembro de soporte. El conjunto de mandril puede estar definido con un perfil que corresponde al perfil de la sección intermedia a engrosar. Además, el aparato incluye un punzón configurado para hacer contacto con un extremo del tubo y ejercer una fuerza axial sobre el tubo para deformar plásticamente el tubo para engrosarlo en su porción intermedia. El aparato facilita el engrosamiento gradual induciendo sólo la localización necesaria del material. Además, el aparato ayuda a retirar fácil y rápidamente el tubo engrosado, lo que reduce el tiempo del ciclo y, por tanto, mejora la productividad. Figura. 1 es una figura representativa.The present disclosure relates to an apparatus for thickening a tube in its intermediate portion along an interior surface. The apparatus includes a first support member for supporting the outer surface of the tube and a mandrel assembly for supporting the inner surface of the tube, wherein the mandrel assembly is supported by a second support member. The mandrel assembly may be defined with a profile that corresponds to the profile of the intermediate section to be thickened. Additionally, the apparatus includes a punch configured to contact one end of the tube and exert an axial force on the tube to plastically deform the tube to thicken it in its intermediate portion. The device facilitates gradual thickening by inducing only the necessary localization of the material. Furthermore, the device helps to easily and quickly remove the thickened tube, which reduces cycle time and therefore improves productivity. Figure. 1 is a representative figure.
