摘要:
An apparatus has a base (3) plate having a plurality of penetrating holes (12), a vertically movable plate (5) slidably mounted on guide posts (1), and a stripper plate (14) slidably mounted on the guide posts and hung from the movable plate. A plurality of stripper pins (13) are vertically slidably mounted in the stripper plate. Each stripper pin is arranged to be inserted in corresponding one of the penetrating holes of the base plate. A sheet holding plate (21) for mounting a product sheet is provided to be detachably mounted on the base plate. The stripper pins are arranged to push each molded rubber product on the product sheet in the corresponding penetrating hole so as to strip it from the product sheet.

L'appareil comporte une pièce porte-poinçons (8), ainsi qu'une matrice (9) et un serre-flanc (10) destinés à enserrer une plaque (11) de circuit imprimé à poinçonner. Le mouvement du porte-poinçon (8) et celui du serre-flanc (10) par rapport à la matrice (9) étant commandés par des vérins (P1, P2), le mouvement d'écartement entre le porte-poinçons et le serre-flanc est aussi commandé par des vérins (P4) indépendants. Les poinçons sont en outre munis d'une seconde arête tranchante qui est orientée en sens inverse de celle de l'arête tranchante d'extrémité et qui est destinée à couper au cours du mouvement de retrait du poinçon. La matrice (9) est montée flottante, et l'ensemble du serre-flanc et de la matrice est muni de moyens de positionnement relatif (17,26) qui s'engagent l'un dans l'autre lorsque le serre-flanc et la matrice arrivent en contact. L'appareil est muni de moyens de chauffage de la matrice et du serre-flanc. Application : fabrication de circuits imprimés.

A knockout device is mounted in a press-machine (1) for knocking out punched work pieces, such as printed circuit boards and the like, which frictionally engage with the punches of the press-machine after the punching operation has taken place. The device comprises, a knockout plate (14) having at least one vertical orifice (14a) therein for the passage of punch means (13) of the press-machine therethrough. The punch means and knockout plate are movable relative to each other by means of a cylinder and piston arrangement (19, 20, 22). A knockout actuation plunger head (23) is reciprocably movable along its central axis and is actuated by said piston which is disposed at a position eccentric to the plunger head.

A wood stump splitting apparatus includes a splitting chamber for receiving a plurality of various sized wood stumps. The splitting chamber has one wall including a splitter grid. Press is provided for pressing the wood stumps against cutting edges of the splitter grid and pushing the plurality of wood stumps through the splitter grid apertures. Press includes a plurality of longitudinal, spaced-apart pushing members which push the stumps through grid apertures and ensure complete extrusion of wood pieces and prevent sticking of the compressed wood pieces in grid apertures.
