Abstract
Sposób kształtowania blach falistych na elementy stożkowego dachu silosu, w którym taśmę metalową poddaje się operacji usunięcia naprężeń szczątkowych w prostownicy (4) rolkowej o wysokiej sztywności konstrukcyjnej, podaje się na nożycę (6) kątową, która odcina kątowo arkusz blachy, który poddaje się, ustawioną pod kątem nożycą (5) krążkową, cięciu wzdłużnemu na niesymetryczne formatki (8), składowane na układaczu (7), po czym formatki (8) podlegają profilowaniu w wieloosiowym module (9) profilowania w procesie wielozabiegowego gięcia wokół roboczych promieni za pomocą zestawu walców (11), w których położenie krawędzi roboczych zmienia się według ustalonego algorytmu sterowania, przy czym zmianie ulega zarówno położenie względem osi wzdłużnej, jak i kąt skręcenia powierzchni roboczej, aż do uzyskania ostatecznego kształtu, zaś formatka (8) przechodząc między kolejnymi parami walców (11) podlega stopniowemu gięciu wokół promieni R1 oraz R2, a zarysy walców (11) profilujących pomiędzy kolejnymi przepustami określają stopień odkształcenia osiągany w kolejnym przejściu, zaś po profilowaniu formatkę (8) przenosi się, poprzez podajnik (10) do automatycznego zespołu perforatorów (12) i wykonuje otwory usytuowane precyzyjnie w strukturze okładziny dachowej, po czym formatka (8) trafia na automatyczny układacz (14).The method of shaping corrugated sheets for the conical silo roof elements, in which the metal strip is subjected to the operation of removing residual stresses in a roller straightener (4) with high structural rigidity, is fed to the angular shear (6), which cuts the sheet metal at an angle which is subjected to, with a roller shear (5) at an angle, longitudinal cutting into asymmetrical forms (8), stored on the stacker (7), then the forms (8) are profiled in a multi-axis profiling module (9) in the process of multi-step bending around working radii using a set rolls (11), in which the position of the working edges changes according to the established control algorithm, whereby both the position in relation to the longitudinal axis and the angle of twist of the working surface are changed until the final shape is obtained, and the form (8) passing between pairs of rollers (11) is subject to gradual bending around radii R1 and R2, and the contours of the profiling rolls (11) between ko through funnel passages determine the degree of deformation achieved in the next pass, and after profiling, the form (8) is transferred through the feeder (10) to the automatic set of perforators (12) and makes holes precisely located in the roof cladding structure, and then the form (8) goes to automatic stacker (14).
