Abstract
Prensa para el forjado de piezas de latón, a partir de bloques en caliente de dicho metal, del tipo formado por una estructura soldada, constituyendo la bancada y el cuerpo superior, y provista de volante de inercia, eje excéntrico y biela de accionamiento del cabezal, caracterizada esencialmente por preverse en el interior de la bancada, un bloque de presión accionado hidráulicamente y sobre el que estará apoyada la mesa inferior de la prensa cuyo bloque, cuando esté activado, mantendrá dicha mesa inferior hacia arriba y en la posición normal de trabajo, lo que permite la absorción de los esfuerzos generados sobre los moldes por la acción del forjado, mientras que cuando deje de estar accionado por dicha presión, permitirá que la mencionada mesa inferior pueda descender una carrera predeterminada, según el dimensionado de las piezas en proceso de forjado, disponiéndose así de un espacio más, que suficiente para que, en caso de bloqueo accidental del cabezal de la prensa, éste pueda finalizar su ciclo operativo. El bloque de presión está constituido por un cuerpo, provisto de una entrada lateral del fluido hidráulico hacia la cámara de presión interior, en forma de corona cilíndrica, y sobre la cual se sitúa el pistón en forma también de corona cilíndrica sustentador de la placa base del bloque que, a su vez, queda sujeta y soporta la mesa inferior de la prensa, estando el mencionado bloque diseñado de modo que permita la ubicación de los mencionados mecanismos extractores para el desmoldeo de las piezas forjadas en la prensa.Press for forging brass parts, from hot blocks of said metal, of the type formed by a welded structure, constituting the base and upper body, and provided with flywheel, eccentric shaft and connecting rod of the head , characterized essentially by being provided inside the bed, a hydraulically operated pressure block and on which the lower table of the press will be supported whose block, when activated, will keep said lower table up and in the normal working position , which allows the absorption of the stresses generated on the molds by the action of the slab, while when it is no longer activated by said pressure, it will allow the mentioned lower table to descend a predetermined stroke, according to the dimensioning of the pieces in process forging, thus providing more space than enough so that, in case of accidental blockage of the press head a, this can end its operating cycle. The pressure block is constituted by a body, provided with a lateral inlet of the hydraulic fluid towards the inner pressure chamber, in the form of a cylindrical crown, and on which the piston is also placed in the form of a cylindrical crown supporting the base plate of the block that, in turn, is held and supports the lower table of the press, said block being designed so as to allow the location of said extractor mechanisms for the demolding of the pieces forged in the press.
