In order to fulfill this goal, the complex research of the influence of the geometrical features of the piercing punch on the perforation force, the hole quality, and the tool life has been conducted. The objective of this paper is to determine the effective geometry of the piercing punches with a spherical bowl used for polymer composite belts.
Research about this process can rarely be found in the scientific literature. Punch optimization is important in improving the technological process of belt perforation.
Additionally, an analysis of the influence of the cutting knife geometry on cutting force is provided. The presented discussion leads to selecting one of the solutions for which a drive system concept designed by the authors is proposed. This article presents three construction concepts of the authors' own design together with an analysis of construction and operating factors which affect their usability. In an attempt to answer the demand of the manufacturing industry, the authors took up design works on an automated device for crosswise cutting of monolithic and composite belts. Considering the above, the subsequent stage of manufacturing requires cutting the belts down to the appropriate length and very often joining the ends to form a closed loop with specific circumference. In order to be usable in the finished conveyor system, correct length of such belts is to be achieved. During the first stage, belts of very high length of up to several hundred meters are manufactured with use of the correct technology for a given belt type. The manufacturing process of flat transport belts usually involves two stages. In both cases, the belts are most often made of plastic materials. One of the basic components of such equipment are flat transport belts which can be monolithic or composite. Belt conveyors are commonly employed in manufacturing and excavation processes.
