Technical justification of the sectional construction of the pressure plate in the die-cutting press
It was stated that the die-cutting equipment belongs to the category of heavily loaded equipment because the drive overcomes significant technological resistances resulting from die-cutting of sweeps. Presses of the equipment are equipped with both wedge-lever mechanisms and eccentric ones to ensure cyclic vertical movement of the pressure plate. It is emphasized that automatic platens create a force loading in the die-cutting of sweeps of more than two hundred tons. A sectional construction of a pressure plate with an eccentric drive was suggested. Such a design of the pressure plate is designed to ensure consistent interaction of the tools of the die-cutting stamp with the sections of the cardboard cutting, to minimize the force loading of the drive. There were obtained values of the displacement invariant of all three sections of the pressure plate, the eccentrics of which are shifted in the angular direction. It was established that an increase in the cardboard thickness requires a similar change in the angular displacement of the eccentrics on the drive shafts in the adjacent sections. Further research on a test stand is planned.

REASONING FOR THE USE OF CRANK-GEAR DRIVE OF PRESSURE SEGMENT IN THE DIE-CUTTING PRESS
There were analyzed the causes for the occurrence of large technological loads in a flat die-cutting press. To minimize them, the use of a segmental pressure device was suggested. This reduces the contact area of “a pressure device and die-cutting stamp” when in pair. As a result, the die-cutting press’s technological loads, metal intensity, and energy content are reduced. Two crank-gear mechanisms installed in parallel were suggested for the drive of the carriage with a pressure cylindrical segment. Such a drive ensures cyclic rolling of the segment on the cardboard cutting, resulting in a reduction in technological loads.

Sectional design of the pressure plate in the die-cutting press with wedging mechanisms: justification of application
The reasons for high technological loads during die-cutting and the design schemes of punching presses are analyzed. Based on the analysis of scientific research, it was found that minimizing the contact area between the pressure plate and the cardboard is necessary to reduce technological efforts. An original pressure plate drive design scheme with sectional construction is proposed. The nature of the joint movement of the sections of the pressure plate is analyzed, and the advantages of the offered die-cutting press are outlined.
