Aim. Carrying out a comparative characterization of the kinematic parameters of the developed flat die-cutting press, the drive mechanism of the movable pressure plate of which includes a cam, rollers, spring and levers, with two laws of periodic movement of the executive link (roller). Method. A flat die-cutting press was chosen as the research material, for which a new design of the drive mechanism of the movable pressure plate was developed, for which a Ukrainian patent for the invention was obtained. Analytical studies of the kinematic parameters of the flat die-cutting press, followed by their comparison, were carried out for two traditional laws of periodic movement of the executive link (roller) for packaging engineering. The geometric dimensions of the flat die-cutting press are chosen taking into account material saving and ensuring compactness. Results. The work established that in the researched flat die- cutting press with given geometric dimensions, the sinusoidal law of periodic movement of the executive link is characterized by the following parameters: maximum speed of the roller Vr = 0,498 m/s, maximum acceleration of the roller Wr = 1,446 m/s2, maximum speed of the pressure plate Vп = 0,193 m/s, maximum acceleration of the pressure plate Wп = 0,588 m/s2. Whereas for the cosinusoidal law of periodic motion, the following indicators are valid: maximum speed of the roller Vr = 0,391 m/s, maximum acceleration of the roller Wr = 1,194 m/s2, maximum speed of the pressure plate Vп = 0,160 m/s, maximum acceleration of the pressure plate Wп = 0,826 m/s2. As a result of the comparative characteristics of the kinematic parameters of the flat die-cutting press, it became obvious that with sinusoidal law of periodic motion, the maximum roller speed is 1,27 times higher, maximum roller acceleration is 1,21 times higher, maximum pressure plate speed is 1,21 times higher, but maximum pressure plate acceleration in 1,40 times lower. Scientific novelty. Analytical studies and comparative characteristics of the developed flat die- cutting press for two laws of periodic movement of the executive link, the drive mechanism of the movable pressure plate consisting of levers, rollers, a cam and a spring, were carried out. It has been demonstrated that the law of periodic movement of the executive link significantly affects the kinematic parameters of the flat die-cutting press with similar geometric dimensions. Practical significance. The obtained results of studies of the kinematic parameters of the flat die-cutting press can be used for further research, in particular for: efforts synthesis of the flat die-cutting press; preparation for refusal; magnitudes of elastic deformations and thicknesses of activation of parts that are in constant contact (a cam and roller).
