The rollforming equipment mainly relies on the plastic movement of materials to roll and process into various complex shaft rods, valve cores, special fasteners and other products. Rolling deformation is line contact, which is carried out continuously and gradually. The required deformation force is small so that one or several workpieces can be produced in one stroke.
Compared with the cutting and grinding process, the roll forming process of the rollforming equipment not only has high production efficiency, saves materials, but also has high product strength and stable quality. This process is especially suitable for processing special lengths and difficult-to-cut workpieces, especially for products with an annual output of millions of pieces. The use of roll forming technology is beneficial, and the economic benefits are also considerable.
Rollforming equipment has good versatility and combination, and is relatively flexible; compared with steel of the same strength, it saves nearly 30% of materials, which effectively controls costs; it has an ultra-long service life, simple maintenance in the later period, and has seismic and compressive bearing capacity; it has the advantages of easy installation, beautiful appearance and space saving.
Rollforming equipment is mainly composed of automatic discharging machine, leveling, feeding part, continuous punching part, forming part, scale cutting part, receiving table, electrical control cabinet and other components. It needs to go through a series of processes such as discharging, leveling feeding, punching, forming, cutting and receiving.
Air source of rollforming equipment: 0.6m3/Min; pressure of 0.7MPa; cutting die material: chromium twelve molybdenum vanadium; cutting size tolerance:≤0.3mm (length≤3000mm); number of main rollers: 14~23 (Depending on the profile); cutting method: hydraulic cutting production speed: 0-12m/min.
