Precision Forming & Bolt-Free Butterfly Hole Application Advantage Focus
Engineered centered around exclusive butterfly hole upright production demands for light-duty storage solutions, Xinnuo’s Butterfly Holes Upright Roll Forming Machine has become a core preferred processing equipment for modern shelving manufacturers pursuing simplified shelf assembly and standardized component production, with every structural module meticulously optimized to realize ultra-precise dimensional control across full production flow. The defining competitive merit of finished uprights fabricated on this line is the patented butterfly hole layout design, which completely abandons traditional bolt fastening mode for shelf assembly; operators can freely install, adjust or disassemble crossbeam accessories without auxiliary fasteners, meanwhile finished shelves support maximum single-layer load of 150KG, perfectly matching daily household, retail and small logistics light storage scenarios. To fully secure precise butterfly hole punching effect, the machine’s hydraulic punching workstation is configured with dual sets of custom-sized 60*35mm Cr12MOV punching molds, after vacuum heat treatment reaching hardness of HRC60~62°, paired with independent 5.5KW hydraulic drive motor, ensuring every hole’s position, aperture and contour stays uniform across all produced upright batches, eliminating manual post-punch trimming work required by outdated punching equipment.
Material adaptability of this roll forming line is locked for thin specification metal sheets within 1.2mm to1.5mm thickness range, covering common industrial cold rolled steel and hot-dipped galvanized steel, the two most widely applied raw materials for lightweight shelving manufacturing globally. The front-end decoller component matches industry-standard large coil parameters: max coil outer diameter 1400mm, inner diameter span 460-520mm, usable coil width 500mm and maximum single coil weight of 3000kgs, its rigid mechanical frame effectively offsets gravity-induced coil deformation during unwinding to keep even material feeding speed into subsequent leveling station. After leveling correction, flat steel strip enters the 20-group customized roller forming section supplemented by 5 dedicated straightening rollers; all roller blanks use high-grade GCr15 steel with heat treatment hardness at HRC57-59° plus fine mirror polishing finish, which avoids coating scratch on galvanized raw materials while maintaining long-term anti-wear performance even under nonstop daily operation. A built-in water cooling circulation system continuously cools high-load forming rollers to restrain thermal expansion caused by long-time friction, further safeguarding long-term forming precision stability.
Terminal hydraulic cut-off unit features standalone 4KW hydraulic station and Cr12MOV cutting dies hardened to HRC57-59°, utilizing stop-fixed cutting mode to lock material before cutting action, restricting finished product length tolerance below 0.5mm, a critical index to guarantee seamless interconnection between upright and matching shelf crossbeams during client’s final assembly procedure. Full machine’s core electrical configuration selects authentic Schneider brand electric parts, constructing transducer-based speed adjustable control system under 380V/50HZ/3PH industrial power supply, operators input target finished upright length parameter via mechanical baffle positioning on control panel, the PLC logic automatically coordinates feeding, punching, forming and cutting rhythm synchronously without manual intercession between processes.

Beyond core production performance, Xinnuo’s complete after-sales protection system enhances long-term usage value for buyers: official 1-year warranty covers machine body, all forming dies and core electrical components, free spare part replacement service is activated for normal-worn accessories within valid warranty term. Compared with scattered multi-process manual production lines that require separate workers for decoiling, punching, forming and cutting respectively, this fully automatic integrated machine drastically cuts on-site labor quantity and corresponding labor expenditure, alongside low inherent failure rate to shrink daily maintenance expense for shelving producers. Apart from standard butterfly hole upright production, Xinnuo’s technical team supports personalized customization of partial forming roller layout and punching mold outline to develop special-spec upright profiles matching clients’ unique shelving design standards, expanding end-product application into cosmetic store display stands, pharmacy storage racks and garage lightweight storage systems.
