Based on the results of the theoretical and experimental studies, the effectiveness of using a multi-blade cutting device for trimming book-journal blocks in the carousel type machines has been established, and the influence of the geometric parameters of the multi-blade cutting device on the quality and accuracy of book-journal blocks trimming during their movement in a circular trajectory has been studied.
The construction of a multi-blade cutting device allows you to adjust the angle of the attack, as well as the depth of cutting of each individual blade. The preliminary analytical and experimental researches of the process of the book-journal blocks trimming with the help of a multi-blade cutting device have shown that the smooth growth of the depth of the blades cutting of a multi-cut cutting tool, as well as the transformation of the cutting angle of individual blades, create prerequisites for qualitative trimming of book-journal blocks.
In order to determine the design of a multi-blade cutting device that provides the necessary quality and accuracy of the book-journal blocks trimming, the software has been developed for the automated calculation of cutting areas with the multi-blade cutting device of book-journal blocks and the visualization of their trimming process. The researches of the trimming process of the book-journal blocks that move along the circular trajectory with the multi-blade cutting device have revealed that it is expedient to use a cutting device which provides two sets of blades. At the same time, the required quality and precision of the trimming is achieved by the symmetric action of the blades of the multi-blade cutting device on the uncut part of the sheets. According to the results of the automated calculation, the most loaded blades of the multi-blade cutting device have been identified, which should be taken into account when designing both a cutting device and a cutting module in general.
Keywords: book-journal block, multi-blade cutting device, trimming process, trimming accuracy, trimming quality, spatial model.
