Development and validation of an automatic bending follower device

The metalworking industry plays a decisive role in the economy. Among the various metal-forming processes, sheet metal bending is essential due to its ability to produce bends with high precision and structural strength. However, the bending quality depends not only on the performance of the bending machine but also on the correct stabilisation of the sheet during the process. In this context, sheet followers are essential auxiliary equipment, designed to accompany the upward movement of the sheet. The main objective of this work was to develop a new sheet follower model, capable of replacing the equipment currently used in a given company. The aim was to design a robust and functional solution that would accurately follow the natural movement of the sheet metal during the bending operation, ensuring operator safety and material integrity. To this end, mechanical design concepts, CAD tools, and structural and kinematic dimensioning methodologies were integrated, as well as the careful selection of materials and manufacturing processes. In addition, the drive system was analysed, costs were estimated, and the proposed solution was compared with competing equipment on the market. This work also aimed to reinforce technical knowledge in the area of auxiliary tilting devices by identifying technological trends and proposing a viable and optimised solution. As a result, the developed bending monitor fully complies with the defined requirements and limitations and demonstrates high functionality and performance. The solution presented is economically more advantageous than the equipment currently in use, without compromising the reliability and accuracy of the process. Thus, all the established objectives were fully achieved, validating the proposal as an effective and competitive alternative for industrial application.
