    摘要: A method and apparatus for high energy rate forming of metal. A die/mould (11) of the shape to which a metal sheet (13) or panels (18) is to be formed is lined with the metal sheet (13) or panels (18) and filled with a liquid medium. A number of explosive charges are then placed at strategic locations within the liquid medium and detonated causing deformation of the metal sheet (13) or panels (18) to the shape defined by the die/mould (11). The die/mould (11) is normally buried in a pit and supported therein during the deformation process. The die/mould (11) consists of longitudinal extending ribs (12) with air spaces (15) therebetween supported by upstanding webs (16) secured to base (17). The air spaces (15) enable air trapped between the metal sheet (13) or panels (18) and the die/mould (11) to escape during the deformation process. A method of forming boat hulls using this method is disclosed.

    摘要: Procédé et appareil pour le matriçage des métaux sous charge élevée de courte durée. Une matrice moule (11) ayant la forme à donner à une tôle métallique (13) ou à des panneaux (18) est garnie avec la tôle métallique (18) ou des panneaux (8) et remplie de liquide. Un certain nombre de charges explosives sont alors placées en des points stratégiques du liquide et mises à feu, ce qui entraîne la déformation de la tôle (13) ou des panneaux (18) et leur donne la forme définie par la matrice moule (11). La matrice moule (11) est normalement enterrée dans une fosse de moulage, sur le fond de laquelle elle repose pendant le processus de déformation. Ladite matrice moule (11) comporte des nervures longitudinales (12) comportant, entre elles, des espaces (15) permettant l'évacuation de l'air emprisonné entre la tôle (13) ou les panneaux (18) et la matrice moule (11) pendant le processus de déformation. Un procédé de matriçage de coques de navires utilisant cette méthode est décrit.

    摘要: In a method of explosively expanding a tubular metal component into engagement with a surrounding metal component, an explosive charge is disposed axially and fired in an insert comprising a hollow cylindrical container fitting closely within the portion of the tubular metal component to be expanded and having charge holding means, for example an axial pocket, to accommodate the explosive charge, the container being filled with a shock wave-transmitting liquid. Compared with solid inserts, the novel hollow insert is cheaper and requires a smaller explosive charge for a given operation. The method is especially advantageous for expanding large diameter tubes.

    摘要: An improved method for the explosive expansion and welding of tubes (14) to tube sheet (10) includes trepanning (at 22) the rear face (20) of the tube sheet to form integral collars (28) around each tube-receiving bore in the tube sheet.
    The collars prevent accumulation of corrosive material in a gap between the tube and tube sheet bore, and provide support to the tube wall when the tube is explosively expanded beyond the region of the tube surrounded by the collar.

    摘要: Procede de reparation et/ou de renforcement d'un systeme de canalisations, selon lequel un organe tubulaire (2) est insere dans une conduite (1) faisant partie du systeme de canalisations, cet organe tubulaire possedant des portions d'extremites scellees et des empreintes, des deformations ou analogues (3, 3') s'etendant longitudinalement, servant a reduire le diametre de l'organe tubulaire (2) par rapport a un cercle enfermant l'organe tubulaire (2), ce diametre reduit etant plus petit que le diametre interne de la conduite (1), une charge explosive (4) avec un dispositif d'allumage associe etant disposee a l'interieur de l'organe tubulaire (2), et une detonation de cette charge explosive (4) provoquant l'expansion de l'organe tubulaire (2) dans une position de contact contre la surface interne de la paroi de la conduite qui l'entoure (1). Les portions d'extremites scellees, ou au moins une de celles-ci, lorsque l'on provoque la detonation de la charge explosive (4) et apres l'etablissement d'une position de contact contre la conduite (1) entourant l'organe tubulaire, sont avantageusement disposees de maniere a pouvoir etre ouvertes et a pouvoir occuper par pression une position de contact etanche contre la conduite (1) autour de l'organe tubulaire.
