Material Adaptability & Diversified Finished Product Application Focus
Xinnuo’s tailor-made Butterfly Holes Upright Roll Forming Machine features targeted material compatibility design focusing on thin-gauge lightweight shelving raw materials, paired with unique butterfly hole forming technology to produce diversified specification uprights widely applicable across household storage, retail supermarket display, pharmacy and small industrial light-load warehouse storage sectors, becoming flexible core production equipment for multi-category light-duty shelf manufacturers worldwide. The machine’s fixed applicable material thickness window falls at 1.2mm to1.5mm, compatible with two dominant commercial steel grades: cold rolled carbon steel and hot-dipped galvanized steel, two materials with distinct physical features to match different end-use environmental requirements of finished shelves. Cold rolled steel-produced uprights feature smooth plain surface and favorable bending toughness, ideal for indoor dry-environment supermarket commodity display racks and household closet storage units with rated single-layer load of 150KG; galvanized steel-made profiles own anti-rust zinc coating layer to adapt damp warehouse, basement and semi-outdoor storage scenarios where moisture easily causes metal corrosion, expanding finished shelf service life in high-humidity application fields.
Front-end feeding decoller is structurally optimized for bulk steel coil production, supporting maximum coil outer diameter of 1400mm, inner diameter scope 460~520mm, fixed 500mm coil width and maximum single coil loading weight of 3000kgs, bulk coil feeding mode fits large-batch continuous production for mass order fulfillment, while built-in leveling unit corrects raw steel sheet surface irregularities to guarantee uniform substrate entering subsequent punching and forming procedures. The inline hydraulic punching workstation with dual-set custom 60*35mm Cr12MOV butterfly hole molds (HRC60~62° hardness) and 5.5KW hydraulic drive motor finishes precise aperture molding synchronously with material advance, the signature butterfly hole structure enables bolt-free quick assembly between upright and shelf crossbeam: users freely alter crossbeam installation height or add optional perforated accessory plates to expand shelf storage partition layout without buying matched fastening bolts, greatly lowering downstream shelf assembly accessory procurement cost for end customers and boosting finished shelf market competitiveness of machine users.
Core cold forming unit is configured with 20 customizable GCr15 forming roller sets (HRC57-59° thermal treatment + mirror polishing finish) plus five independent straightening rollers, gear-and-gearbox power transmission ensures synchronized roller rotation accuracy, matched circulating water cooling system dissipates continuous-running heat of forming rollers to prevent high-temperature induced dimensional deviation of formed profiles. Terminal hydraulic cutting unit equipped with standalone 4KW hydraulic station and Cr12MOV cutting dies (HRC57-59°) implements stop-position cutting technology, controlling finished upright dimensional tolerance strictly below 0.5mm to guarantee interchangeability of spare upright accessories for end shelf users. Full machine’s control system assembles authentic Schneider brand electric parts, powered by standard industrial 380V/50HZ/3PH supply, transducer stepless speed regulation adjusts production running speed from low trial speed up to top limit of 20 meters per minute flexibly based on material type and daily order volume.
