Roll forming equipment primarily utilizes the plastic movement of materials to roll and process them into various complex shapes of shafts, valve cores, and special fasteners. Roll forming deformation is a line contact process, carried out continuously and gradually, requiring relatively small deformation forces; one stroke can produce one or several workpieces.
Compared to cutting and grinding processes, roll forming not only offers higher production efficiency and material savings, but also produces products with higher strength and more stable quality. This process is particularly suitable for processing workpieces that are too long or short to be easily machined, especially for high-volume production of millions of pieces annually, where roll forming is advantageous and offers considerable economic benefits.
Roll forming equipment boasts good versatility and modularity, offering considerable flexibility; compared to steel of equivalent strength, it saves nearly 30% of materials, effectively controlling costs; it has an exceptionally long service life and simple maintenance; it possesses strong vibration and compressive load-bearing capacity; it is easy to install, aesthetically pleasing, and space-saving.
Roll forming equipment mainly consists of components such as an automatic feeding machine, leveling and feeding section, continuous punching section, forming section, length cutting section, receiving table, and electrical control cabinet. It requires a series of processes including feeding, leveling and feeding, punching/notching/perforation, forming, cutting, and receiving.
