Abstract
The analysis of existing publications highlights a gap in scientific research on mechanisms used in the drive system to move the pressure plate, particularly those that extend the contact duration between the die-cutting mold and cardboard. The authors developed a kinematic scheme of the proposed double-wedging mechanism. The geometric synthesis and kinematic analysis of the mechanism were performed, determining the relative values of key geometric parameters, displacement, velocity, and acceleration of the pressure plate. The geometry and kinematic parameters were calculated using mathematical models based on similarity invariants. To validate the results, a simulation of the work process was conducted in the SolidWorks program for the double-wedging mechanism and the existing mechanism used in Bobst presses. A comparative analysis of the analytically obtained kinematic dependencies and the simulation results demonstrated absolute agreement, confirming the accuracy of the developed mathematical models. The results of the kinematic analysis indicate that using a combined two-wedging mechanism doubles the duration of the die-cutting tool with the cardboard blank. This prolonged contact positively impacts the efficiency of die-cutting operations, particularly for creasing and relief embossing.
