The establishing the influence of the law of periodic motion on the drive mechanism of the movable pressure plate on the kinematic parameters of the flat die-cutting press

Aim. Analytical research of the influence of the law of periodic motion on the drive mechanism of the movable pressure plate on the kinematic parameters of the flat die-cutting press. Method. The material of the research was a flat die-cutting press, the drive mechanism of the movable pressure plate of which includes cams and rollers. For the researched flat die-cutting press, a structure was developed, which is protected by a patent of Ukraine for a utility model. Analytical research of the maximum values of the kinematic parameters for the roller and the moving pressure plate under six laws of periodic motion of the roller were carried out. A comparative analysis of the obtained research results was carried out. Results. The established that the law of periodic movement of the drive mechanism of the movable pressure plate with the same geometric dimensions significantly affects the kinematic parameters of the die- cutting press. With the selected geometric dimensions, the maximum values of the roller`s linear speed Vr  differ by m/s²; the maximum value of the linear speed of the pressure plate Vn by 1.37 times, and is 0.194 m/s, and the maximum value of the linear acceleration of the pressure plate Wn by 5.67 times, and is 1.001 m/s². Scientific novelty. Analytical research of the influence of the law of periodic movement of the drive mechanism of the pressure plate on the kinematic parameters of the flat die-cutting press for which the design was developed were carried out. The fundamental importance of the rational choice of the law of periodic motion has been established, which is especially, one might say critically, important for flat die-cutting presses, which are characterized by significant technological efforts that occur during the technological operation of die-cutting cardboard packaging blanks and high work productivity. Practical significance. The obtained results of the analytical research of the influence of the law of periodic motion demonstrated that with similar geometric dimensions of the drive mechanism of the movable pressure plate, the kinematic parameters of the flat die-cutting press can differ significantly. The laws of periodic motion are established, which are characterizes by the maximum and minimal indicators of kinematic parameters for the drive mechanism of the movable pressure plate under research.
