Abstract

"GABARITO PARA EXPANDIR UMA ABERTURA DE UM TUBO DE TROCADOR DE CALOR". A invenção se refere a um gabarito para expandir uma abertura de um tubo de trocador de calor, sendo que o gabarito inclui uma lâmina de expansão (220) e um corpo principal (210). A lâmina de expansão (220) se salienta do corpo principal (210) em direção a uma abertura (111a) do tubo (111). A lâmina de expansão (220) é disposta em uma posição predeterminada que corresponde a um lado estreito (111b) da abertura (111a) do tubo (111). A lâmina de expansão é capaz de se mover para o interior do tubo (111), de modo que o lado estreito (111b) do tubo (111) é expandido. A lâmina de expansão (220) inclui uma superfície (220a) tendo uma forma de adelgaçamento, a qual se inclina no lado estreito (111b) para uma extremidade de topo (220b) da lâmina de expansão (220), em um caso onde a lâmina (220) é inserida no tubo (111).
