Abstract

La présente invention regarde un frein de stationne­ ment pour presses mécaniques ou hydrauliques, capable de retenir immobile la masse arrêtée, tout en permettant le glis­ sement si l'on actionne les dispositifs spéciaux de réglage-­ masse, comme par exemple pendant la phase de change d'étampes. The present invention relates to a parking brake ment for mechanical or hydraulic presses, capable of hold the stopped mass still, while allowing the glis if the special adjustment devices are activated- mass, such as during the exchange phase of stamps.

Selon la forme préférée de réalisation, l'invention com­ prend, fondamentalement, un piston pneumatique dont la tige plonge dans un cylindre hydraulique, où l'huile portée en pression pousse en avant un piston qui a, sur la face extérieure, une crête frontale, diamétrale et cunéiforme, qui va presser et s'encastrer dans une rainure longitudinale conforme, creusée le long d'une génératrice d'un arbre qui traverse transversalement le cylindre hydraulique et qui résulte ancré à la masse. According to the preferred embodiment, the invention com basically takes a pneumatic piston whose rod immersed in a hydraulic cylinder, where the oil carried in pressure pushes forward a piston which has, on the face outer, a frontal, diametral and cuneiform ridge, which will press and fit into a longitudinal groove conform, dug along a generator of a tree which crosses the hydraulic cylinder and which results anchored to ground.
