AUTOMATED SYNTHESIS OF MECHANISM OF PRESS OF DIE-CUTTING MACHINE

Vlakh V., Pasika V.

Die-cutting consists of whole complex of operations that help to determine the shape, geometric dimensions and design of cardboard packaging. This process occurs on crucible and rotational die-cutting machine. Working tools are combined die-cutting form, by which all operations are performed simultaneously during one operating run. This article describes the methodology of optimizing the main press mechanism of die-cutting machine that enables improvement of productivity and manufacturing quality and also power reduction of machine drive. The authors investigated analytical dependence on the basis of which synthesis is conducted, software is developed as a tool for analysis and synthesis of investigated mechanism.

ANALYSIS OF SOFTWARE FOR RESEARCH OF MECHANISMS OF PRINTING AND PACKAGING PRESSES
V. V. Vlakh

Kinematic and dynamic analysis of mechanisms is a necessary stage in the development of new printing and packaging presses, as well as improving the existing ones. Today there are many types of software which you can use to calculate mechanisms on kinematic and dynamic characteristics. The analysis on the Internet has shown that professional computer aided design, which enable to conduct kinematic and dynamic analysis, need additional knowledge to work with them, large hardware resources of the computer, and are very expensive. After several attempts of scientists and engineers to create a cheap, easy to use and feature rich tool have failed. In Europe and the US they have developed solutions that can be used only in professional powerful systems. So the creation of multifunctional, easy to use and inexpensive software for calculating mechanisms is important.

RESEARCH MECHANISMS OF PRINTING AND PACKING MACHINES IN SPECIALIZED CAD

V. V. Vlakh

The author of this article has created computer program to calculate mechanisms. The first version of the program allows to visually create a kinematic scheme of the test mechanism, see an animation of the motion, to conduct kinematic analysis and to take 3D-model that can be applied to other, more powerful systems.The program can be used in the educational process.This article describes the possibilities offered by this CAD on example analysis of mechanisms of printing and packaging machines.

METHODOLOGY OF IMPLEMENTATION OF DATA EXPORT, VISUALIZATION AND CREATING 3D MODEL OF MECHANISM IN SPECIAL CALCULATION SYSTEM

V. V. Vlakh

The article examines the methods by which the visualization of mechanisms is created and the transfer of data from specialized software to AutoCAD is done. The software created in Embarcadero Rad Studio Delphi by using object-oriented programming methods. That largely enabled the export of the kinematic scheme of the mechanism and create AutoLISP program, which describes the 3D model.

MODIFICATION OF A DRIVE MECHANISM OF A PRESS PLATE IN A DIE-CUTTING PRESS

V. О. Kuznetsov, I. І. Rehey, V. V. Vlakh

The article is focused on the design of a drive mechanism of a press plate used in the die-cutting units. It has been identified that the plate is driven via a hinge-lever mechanisms that create the «unwedging» effect necessary to overcome significant technological resistances in the cardboard patterns manufacturing. The analysis of kinematic parameters of crossheads motion has been performed, an asynchronous movement of left and right crossheads has been found out. An alternative drive mechanism of lower press plate has been designed on the basis of master and slave couples of crank-crosshead contours. Mathematical dependences has been derived for the evaluation of kinematic motion of a press plate crossheads. It has been identified that the crossheads move in direct and reverse directions with the same speeds, providing a parallel position of a press plate relatively to the surface of immovable support plate, and the process of punching is completed with no acceleration of the moving plates.

KINEMATIC SYNTHESIS OF DIE-CUTTING PRESS MECHANISM WITH EQUALITY OF FORWARD AND REVERSE MOVES

V. R. Pasika, V. V. Vlakh

The construction of die-cutting presses which consist of the fixed plate with form, the pressure plate, the levering and eccentric mechanisms is characterized by drawbacks due to the fact that the eccentric mechanisms installed diagonally on the drive shaft provide an oscillatory motion to the pressure plate for a period of working and idle moves. It has a negative effect on quality of stamping of the card-board sweeps, degrades the stability of work of the press and limits its performance. This article deals with the kinematic synthesis of this mechanism, which allows increasing the productivity of the press.

A DRIVE MECHANISM OF PRESS PLATE OF DIE-CUTTING MACHINE

I.I. Regey, V.A. Kuznetsov, V.V. Vlakh

In this article it is considering a new mechanism of a drive of the press plate of the die-cutting machine. This mechanism is based on a combined mechanism and consists of driving and driven slider-crank contours. Kinematic analysis describes that the sliders of the press plate move with the same speed, also it safes parallelism to the stationary plate. The press plate stops in extreme position without acceleration.
