Long-Term Durability & Low Failure Rate Engineering Design Focus
Constructed with wear-resistant premium raw materials and optimized mechanical transmission layout for long-duration uninterrupted industrial production, Xinnuo’s Butterfly Holes Upright Roll Forming Machine delivers outstanding long-term durability and ultra-low daily failure rate, greatly reducing unplanned production halt loss and periodic component replacement expense for light-duty shelving manufacturers relying on continuous batch upright fabrication. Every core wear-prone working component of the whole production line selects high-hardness alloy steel with standardized professional heat treatment craft to extend usable service life: hydraulic punching station’s dual customized 60*35mm butterfly hole molds adopt Cr12MOV alloy steel processed to HRC60~62° hardness, this tool steel grade features exceptional anti-impact and anti-abrasion performance to resist repeated high-frequency stamping impact from 5.5KW hydraulic driving motor during daily long-hour punching work, avoiding early mold edge collapse or aperture deformation after tens of thousands of stamping cycles. Central cold forming section’s total 20 customizable forming roller groups plus five straightening rollers are fabricated from premium GCr15 bearing steel with thermal treatment to HRC57-59°, followed by precision mirror surface polishing to cut down friction abrasion between roller surface and incoming thin steel sheet (1.2~1.5mm thickness cold rolled/galvanized steel); matched gear-and-gearbox enclosed transmission structure prevents dust and steel scrap from invading transmission gear gaps, effectively lowering gear tooth abrasion and gear jamming failure probability compared with open chain transmission used on low-cost inferior roll forming machines.
A dedicated circulating water cooling system is preinstalled surrounding high-load forming roller groups to continuously take away friction-generated heat during high-speed forming (top rated speed 20 meters per minute), preventing roller thermal expansion-induced forming dimension deviation and accelerated surface abrasion under long-time continuous running condition, further prolonging forming roller’s effective service cycle. Front-end decoller built for bulk coil production (max coil weight 3000kgs, outer diameter1400mm, inner diameter460~520mm, width500mm) uses thickened welded steel plate base frame to offset long-term heavy coil loading fatigue deformation, its internal unwinding bearing parts adopt heavy-duty sealed bearings with pre-filled anti-rust lubricating grease to reduce regular bearing maintenance frequency and bearing wear failure risk. Terminal hydraulic cut-off unit’s Cr12MOV cutting dies receive HRC57-59° hardness heat treatment, driven by standalone 4KW hydraulic station with built-in oil filter device to isolate hydraulic oil impurity particles from hydraulic cylinder inner cavity, avoiding valve blockage and cutting power insufficiency caused by contaminated hydraulic oil, the stop-then-cut working logic also reduces unnecessary idle cutting impact on cutting blade edge.
