Title
(EN) SHELL PRESS AND METHOD FOR FORMING A SHELL
(FR) PRESSE D'ÉBAUCHAGE ET PROCÉDÉ PERMETTANT DE FORMER UNE ÉBAUCHE
Abstract
(EN)
An apparatus and method for forming a shell with a central panel and a chuck wall is provided. The apparatus and method employ the use of a biasing member to selectively bias and control movement of the inner pressure sleeve and a die core having an outer diameter equal to or greater than the outer diameter of the punch core. The apparatus and method can also be employed in a single action press or a double action press.
(FR)
L'invention concerne un appareil et un procédé permettant de former une ébauche avec un panneau central et une paroi de serrage. L'appareil et le procédé font appel à l'utilisation d'un organe de sollicitation pour solliciter et commander de manière sélective le mouvement de la gaine de pression intérieure et un noyau de matrice ayant un diamètre extérieur égal ou supérieur au diamètre extérieur du noyau de poinçon. L'appareil et le procédé peuvent également être utilisés dans une presse à simple effet ou dans une presse à double effet.
