Abstract

La invencion se refiere a una herramienta para regular la presion superficial sobre una pieza sin terminar constituida por una plca de chapa de metal que constituye la pieza de partida para conformar una pieza terminada en una prensa. La pieza sin terminar se coloca entre un anillo (23) de embuticion y un anillo (24) de sujecion de la pieza sin terminar. Adicionalmente la herramienta comprende una placa (1, 5, 10) de compensacion en la que se proporcionan cámaras (2, 3, 4, 6, 7, 8, 9, 11, 12, 13, 14) que se delimitan mediante la placa de compensacion misma y mediante una membrana (27) flexible. La placa de compensacion se coloca entre una parte (17) inferior de la herramienta, alternativamente una parte (16) superior de la herramienta, y el anillo de sujecion de la pieza sin terminar, alternativamente el anillo de embuticion. Es posible conducir al interior de las cámaras un medio de presion, como aceite hidráulico. Mediante eso es posible incrementar local e individualmente la presion superficial sobre la pieza sin terminar en funcion del n°mero de cámaras, el diseño de las cámaras y la ubicacion de las cámaras en la plca de compensacion. Adicionalmente es posible regular la presion durante el proceso mismo de conformacion.
