Full-Automatic Integrated Production & High-Speed Output Focus
The Butterfly Holes Upright Roll Forming Machine from Xinnuo Machine stands as a fully integrated automated industrial production line specially customized to manufacture light-duty storage rack uprights prefabricated with exclusive butterfly-shaped assembly holes, catering to global manufacturers focused on lightweight commercial shelving production. Consolidating five core functional modules into one seamless inline workflow: decoller unit, material leveler, hydraulic punching station, multi-station roll forming host, and hydraulic fixed-length cutting system, this equipment eliminates disjointed standalone processing procedures that plague traditional discrete production equipment, realizing uninterrupted one-step fabrication starting from raw steel coil feeding all the way to finished upright output. Its standout production capability lies in a maximum running speed capped at 20 meters per minute, a remarkable specification that drastically lifts daily batch production capacity compared with conventional low-speed roll forming equipment widely used in small-scale shelf workshops across the industry.
Starting from the raw material feeding end, the standard matched decoller is engineered to accommodate heavy steel coils with outer diameter of 1400mm, inner diameter ranging from 460mm to 520mm, maximum coil width at 500mm, and single coil loading weight up to 3000kgs, effectively supporting long-duration continuous feeding without frequent coil replacement downtime. Following the decoiling segment, the built-in leveling mechanism removes inherent surface bending and uneven deformation on incoming thin steel sheets, laying flat raw substrates to guarantee uniform precision during subsequent punching and cold forming processes. The core hydraulic punching assembly is equipped with 2 sets of customized 60*35mm butterfly hole molds crafted from Cr12MOV alloy steel, receiving precise heat treatment to reach hardness of HRC60~62°, while the entire punching unit is driven by a robust 5.5KW dedicated hydraulic motor. This configuration ensures every punched butterfly aperture maintains standardized dimension consistency, the core structural feature enabling bolt-free quick assembly for finished light-load shelves with maximum rated bearing capacity of 150KG per layer.
The central roll forming section adopts 20 customizable forming roller stations plus 5 auxiliary straightening rollers, all forming rollers manufactured from premium GCr15 bearing steel with thermal treatment to hit hardness of HRC57-59° and mirror polishing surface finishing to avoid scratching thin raw steel surface during cold bending. A professional circulating water cooling system is preinstalled for the forming host to dissipate continuous operation heat, preventing thermal expansion deformation of precision rollers during round-the-clock industrial production. Power transmission between each forming station relies on mature gear and gearbox linkage structure, delivering stable torque output and minimizing transmission clearance that would cause irregular profile distortion.

At the terminal of the whole production line sits the hydraulic cut-off device fitted with Cr12MOV cutting molds hardened to HRC57-59°, powered by an independent 4KW hydraulic station, adopting stop-then-cut working logic to lock material position before every cutting stroke, delivering finished uprights with cutting dimensional tolerance controlled within ≤0.5mm. The entire machine’s operational logic is managed by a standardized electric control system assembled with original Schneider core electrical components, running on industrial power specification of 380V,50HZ,3PH, with production length set via mechanical baffle positioning and production speed dynamically regulated by high-precision transducer. From after-sales perspective, Xinnuo provides a full 1-year official warranty covering machine main frame, all forming dies and core electrical spare parts, with free component replacement service for damaged standard accessories arising from normal production wear within warranty period. This machine is exclusively designed to process thin-gauge raw steel ranging from 1.2mm to1.5mm in thickness, including cold rolled steel and galvanized steel substrates, producing lightweight yet structurally stable uprights for supermarket display racks, household storage shelves and small warehouse light-load storage systems, with optional customized perforated plate accessory solutions to enrich finished shelf application diversity for downstream clients.
