VIBRATING MACHINE FOR PRODUCING MOLDED BODIES BY MEANS OF COMPACTING

摘要

Vibrating machines for producing molded bodies by means of compacting granular raw mixtures in a vibratory manner for the purpose of molding in particular heavyweight anode blocks nowadays include a vibrating table which is mounted so as to be able to oscillate, onto which a molding box (12) to be filled with a raw mixture charge can be placed, on the top side of which molding box a cover (15) can be placed once a cover weight (13) has been introduced. The secure clamping of the unit of molding box/cover, which oscillates with the vibrating table, to the top side of the vibrating table (10) is important during the vibrating operation. To this end, the invention proposes clamping closures with pivot bracket (17), hydraulic pivot cylinder (18), rocker arm (19) and compression spring (20) that cooperates therewith, said compression spring being insensitive to oscillating stresses.
