In this section there are examples of profiles designed to solve even the most complex geometries. Each profile corresponds to the new nomenclature "F", F1, F2 up to the latest studies that arrive abundantly beyond the number 100. With this new approach, for each "F" profile, Rolleri proposes at least 5 solutions able to bend the profile through studies and sequences of reworked folds. The profile, the number of items to be bent and the characteristics of the bending press used are considered: length, span, stroke, power and tangs. With these elements the most appropriate study is prepared, evaluating together with the customer the best solution for the return on investment.
Each proposal includes an example through a drawing with all the bending sequences. For shorter parts, the possibility of working at a station is always evaluated in order to reduce machining times through a single set-up of the press brakes. For longer profiles, on the other hand, tilting is reduced to a minimum, always paying great attention to operator safety.
Thanks to this new approach, it will be possible to evaluate a study with standard tools, with modified standard tools and with multi-fold design dies or the combination of the 3 possibilities. For some applications Rolleri produces the mould sample with the wire EDM department or for some tools, through CAD, we send the file to the new 3D printing machines to have the prototype made in a few hours and immediately start the bending tests.
