EXPERIMENTAL RESEARCH OF PAPERBOARD CREASING IN DIE-CUTTING PRESS WITH SCREW-NUT MECHANISM FOR DRIVE OF THE MOVABLE PRESSURE PLATE

Abstract: The paper reports experimental research of torque values during paperboard creasing in the die-cutting press with the screw-nut transmission as the drive mechanism of the movable pressure plate. The purpose of the study is to get experimental data for analytical calculations of the proposed drive mechanism of the pressure plate at the stage of its design for substantiation of its practical implementation for the production of cut-outs of paperboard packaging. Experimental research of paperboard blanks creasing allows getting dependencies of torque values on parameters of paperboard and regimes of experimental bench working. Results of experimental research allow getting trustworthy and systematised information about torque values depending on the thickness of the paperboard, the paperboard fibres direction and pressure plate displacement velocity. The article shows the workability of the designed device with the screw-nut transmission in the drive mechanism of the movable pressure plate.
