FIELD: metallurgy.
SUBSTANCE: invention relates to press-forging equipment, particularly to mechanical presses. Sheet-metal press of double-acting contains stand, main actuator connecting rod gear, sheets-clipping mechanism, driver and actuation system. Sheets-clipping mechanism corresponds two four-level mechanism with total output link in the form of external slide block. On stand there are fixed travelling supports and fixing devices. Each of four-level mechanism contains input link in the form of rockers, fixed on shaft, which is rigid to output shaft of gear-motor drive. Fixing device is implemented in the form of pawl, spring, electromagnet and fixed on disc shaft with hollows by form of pawl.
EFFECT: it is provided reduction of mobile links and coupling amount, accurate dwell of external slide block and the ability of disconnection sheets-clipping mechanism during the control of cupping die.
