ABSTRACT:
Apparatus for periodically sensing and cooling the end face of one or more rams of an automatic cross transport press. In a cross transport press, on the press frame (1) there is mounted a sensing rocker (9) which executes a periodical rocking movement about a horizontal axis (A) in the work rhythm of a carriage (2) provided with rams (5). The movement of the sensing rocker (9) is transmitted from the carriage (2) through a connecting rod (20), a transmission lever (17) and the two rocker arms (8) to sensing elements (27) equipped with cooling sprinklers. The slightly angled transmission lever (17) rests upon a stop (15) and is retained upon the stop (15) by a spring (25). If a sensing element (27) encounters an obstacle, then the press is stopped; simultaneously the transmission lever (17) lifts from the stop counter to the return force of the spring (25), whereby any damage is prevented. The sensing rocker can be pivoted upwards into a rest position if a pneumatically loaded piston is used instead of the spring (25).
