Cost Optimization & Low Operation Maintenance Focus
Focused on helping light-duty shelf manufacturers slash comprehensive production expenditure and reduce routine equipment maintenance burden, Xinnuo’s Butterfly Holes Upright Roll Forming Machine is developed as a full-automatic integrated cold forming production line that restructures traditional fragmented upright production cost composition from raw coil to finished goods, achieving evident economic benefits in labor input, raw material wastage and long-term equipment upkeep three core dimensions. Conventional discrete upright production requires independent workers stationed at decoiling, punching, forming and cutting four separate stations, yet this integrated roll forming equipment combines all five core working units (decoller, leveler, hydraulic puncher, roll former, hydraulic cutter) into one linked automated workflow, needing merely 1~2 on-site operators to monitor full-line running status, drastically cutting monthly labor payroll for manufacturing enterprises. Its maximum stable forming speed hits 20 meters per minute, far outpacing manual-assisted semi-automatic production lines whose average speed hovers below 8 meters per minute, lifting monthly finished upright output to amplify order revenue capacity for clients without extra workshop area expansion investment.
Starting from raw material input link, the equipped heavy-duty decoller can bear single coil weight up to 3000kgs, with applicable coil outer diameter of 1400mm, inner diameter between 460mm~520mm and fixed coil width of 500mm; large-spec coil bulk procurement helps shelf factories obtain lower raw steel unit price from steel suppliers, while the decoller’s steady unwinding structure reduces edge wrinkling and skew of steel strip that would lead to scrapped raw materials, cutting material waste ratio notably compared with small-coil frequent replacement mode. Target processing material thickness is fixed at 1.2mm~1.5mm thin steel plate including galvanized and cold rolled variants, the mainstream cost-effective substrate for light-load shelving whose finished upright can bear 150KG single-layer shelf load with lightweight self-weight to save subsequent transportation cost of finished shelving goods for downstream sellers.
The hydraulic punching station installed with dual customized 60*35mm Cr12MOV punching molds (HRC60~62° hardness) and 5.5KW driving hydraulic motor delivers precise butterfly hole molding in one inline pass, eliminating secondary manual hole trimming procedure and corresponding extra labor cost. Central forming section owns 20 groups customizable GCr15-made forming rollers (HRC57-59° heat treatment + mirror polishing) plus five auxiliary straightening rollers, gear-box driven transmission structure reduces mechanical failure probability of roller transmission parts, while attached water cooling system slows down roller abrasion speed by lowering continuous-operation high temperature, extending roller service cycle and cutting frequent roller replacement expense. Terminal stop-then-cut hydraulic cutting system with 4KW independent hydraulic station and Cr12MOV cutting dies controls finished upright dimensional tolerance within ≤0.5mm, minimizing length out-of-spec finished product scrap caused by inaccurate cutting.
