Title (EN) STEELPAN MUSICAL INSTRUMENT HYDROFORMING PRESS
(FR) PRESSE D'HYDROFORMAGE D'INSTRUMENT DE MUSIQUE DE TYPE STEELPAN
Abstract:
(EN) A machine can form a work piece into a bowl subcomponent of a steel pan musical instrument. The machine includes a pressure lid and a die mold. The die mold may be formed of non-metal layers stacked between metal layers. In example operation, a blank or work piece is inserted between the lid and die mold. The lid is pressed down (e.g., by a hydraulic ram), forcing a portion of the blank into a face groove of the die mold for sealing. Pressurized water or other fluid introduced between the lid and the blank exerts pressure on the sealed portion of the blank and stretches the blank to conform to a bowl shape of the die mold. Note regions can be introduced by this machine-performed shaping and/or by subsequent manual operations to further prepare the work piece for incorporation into a steel pan musical instrument.
(FR) Une machine peut former une pièce à travailler en un sous-composant de type bol d'un instrument de musique de type steelpan. La machine comprend un couvercle de pression et un moule à matrice. Le moule à matrice peut être formé de couches non métalliques empilées entre des couches métalliques. Dans un mode de réalisation donné à titre d'exemple, une ébauche ou pièce de travail est insérée entre le couvercle et le moule à matrice. Le couvercle est pressé vers le bas (par exemple, par un vérin hydraulique), forçant une partie de l'ébauche dans une rainure de face du moule à matrice pour obtenir une étanchéité. De l'eau sous pression ou un autre fluide introduit entre le couvercle et l'ébauche exerce une pression sur la partie scellée de l'ébauche et étire l'ébauche pour qu'elle se conforme à une forme de bol du moule à matrice. Il convient de noter que des régions peuvent être introduites par cette mise en forme réalisée par machine et/ou par des opérations manuelles ultérieures pour préparer plus avant la pièce à travailler à l'incorporation dans un instrument de musique de type steelpan.
