Title (EN) DIE-CUSHION DEVICE
(FR) DISPOSITIF DE COUSSIN SERVANT DE MATRICE
(JA) ダイクッション装置
Abstract: front page image
(EN)Provided is a die-cushion device that can shorten the build-up time of the pressing force on slides. The die-cushion device is provided with a cushion pad, a support, a servomotor, and a cushioning device (12). The support holds the cushion pad. The servomotor raises and lowers the cushion pad by raising and lowering the support. The cushioning device (12) has an orifice (33) and mitigates shock between the cushion pad and the support. The orifice (33) generates a reactive force that corresponds to the relative speed of the cushion pad with respect to the support.
(FR)La présente invention se rapporte à un dispositif de coussin servant de matrice qui peut raccourcir le temps d’accumulation de la force de pression sur des coulisseaux. Le dispositif de coussin servant de matrice est équipé d’un rembourrage de coussin, d’un support, d’un servomoteur, et d’un dispositif d’amortissement (12). Le support maintient le rembourrage de coussin. Le servomoteur soulève et abaisse le rembourrage de coussin par le soulèvement et l’abaissement du support. Le dispositif d’amortissement (12) comporte un orifice (33) et atténue les chocs entre le rembourrage de coussin et le support. L’orifice (33) génère une force de réaction qui correspond à la vitesse relative du rembourrage de coussin par rapport au support.
(JA) スライドへの押付力の立ち上がり時間を短縮させることができるダイクッション装置を提供する。ダイクッション装置は、クッションパッドと、支持部と、サーボモータと、緩衝装置(12)と、を備える。支持部は、クッションパッドを支持する。サーボモータは、支持部を昇降させることによりクッションパッドを昇降させる。緩衝装置(12)は、オリフィス(33)を有し、クッションパッドと支持部との間での衝撃を緩和させる。オリフィス(33)は、支持部に対するクッションパッドの相対速度に応じた反力を生じさせる。
