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.

“…A new design of the pressure plate drive of the die-cutting press using a screw-nut transmission in the drive mechanism of the pressure plate has been proposes [10] and an evaluation [11] of components of the consumed kinetic power in the pressure plate drive with screw-nut transmission has been conducted. Experimental research on torques during cardboard cutting in the die-cutting press with the screw-nut transmission in the drive mechanism of the movable pressure plate [12] show that the use of die-cutting presses built on such design enables and allows avoiding drawbacks of existing die-cutting presses in the area of pressure plate movement unevenness during the kinematic cycle.…”

The paper reports experimental research on torques during cardboard cutting in the die-cutting press with eccentrics in the drive of the movable pressure plate. To conduct the research, an experimental bench with eccentrics in the drive of the die-cutting press is designed and manufactured. The manufactured experimental device for the research on cardboard blanks provides the possibility of getting dependencies of loadings at different parameters of the die-cutting process. The experimental approach envisages the use of the strain gauge measurement method and the wireless module for data collecting, as well as the software for its processing, for getting trustworthy results with minimum faults. The method gives an opportunity to study the torque values during the cardboard-cutting efforts on the drive shaft. The paper shows changes in the torque value on the drive shaft during the kinematic cycle with and without the use of cardboard blank. The angle of the drive shaft rotation during the cutting process was evaluated at selected values of the cardboard thickness. The relationship between the linear cutting efforts and the cardboard thickness, its fibre direction, cutting rule type and rotational speed of the drive shaft is elaborated. This kind of data is approximated by a logarithmic function (logarithmic curve), at R 2 from 0.90 to 0.98. The thickness of the cardboard significantly influences the value of the linear cutting effort at all the studied parameters.
