Traction Slippage:<\/span><\/b> When processing coiled rebar (especially 8 mm and 10 mm deformed bars), the residual twisting stress caused standard 4-wheel or 6-wheel feeding mechanisms to slip<\/span><\/span>. <\/span>This resulted in inaccurate length positioning and subsequent bending point misalignment, driving their scrap rate up to an unsustainable 8%\u201310%<\/span><\/span>.<\/span><\/p>\n<\/li>\n Angular Inertia Deviation:<\/span><\/b> When fabricating large-scale stirrups at high speeds, the bending mechanism could not brake instantly<\/span><\/span>. <\/span>The resulting inertial overshot created inconsistent angles between corners, forcing workers to spend substantial time on manual secondary corrections<\/span><\/span>.<\/span><\/p>\n<\/li>\n<\/ol>\n To break this cycle of material waste and low efficiency, we deployed the <\/span>VLGW12B Automatic CNC Rebar Bender<\/span><\/b><\/a><\/span>. <\/span>This case study details how its specialized structural engineering eliminated these core issues, drastically boosting yield and reducing labor dependencies<\/span><\/span>.<\/span><\/p>\n The VLGW12B is engineered with a heavy-duty 2000 kg rigid frame and optimized dimensions (<\/span>$4005 \\times 1100 \\times 2200\\text{ mm}$<\/span>) to ensure structural stability during high-intensity, continuous operations<\/span><\/span>.<\/span><\/p>\n <\/p>\n <\/p>\n The definitive highlight of the VLGW12B is its proprietary <\/span>8-wheel traction mechanism<\/span><\/b>, an industry-exclusive engineering design<\/span><\/span>.<\/span><\/p>\n While typical market alternatives rely on 4 or 6 traction wheels, this heavy-duty

dramatically expand the grip contact area and clamping force<\/span><\/span>. <\/span>No matter how severely the coiled rebar is twisted, the system securely locks and continuously feeds the stock without rotational deviation or slippage<\/span><\/span>.<\/span><\/p>\n The Result:<\/span><\/b> Even at its maximum feeding speed of 110 m\/min, the length tolerance is strictly held within <\/span>$\\pm 1\\text{ mm}$<\/span><\/span>. <\/span>In on-site client trials, this advanced <\/span>\u0645\u0627\u0643\u064a\u0646\u0629 \u062b\u0646\u064a \u062d\u062f\u064a\u062f

servo motor and an advanced PLC automation system<\/span><\/span>.<\/span><\/p>\n Operators can input or select from hundreds of pre-stored geometric processing shapes directly through the localized multi-language touch screen<\/span><\/span>. <\/span>The control system features smart automatic angle compensation<\/span><\/span>. <\/span>By fine-tuning the deceleration curve based on the specific stirrup leg lengths and bar diameters, the dynamic inertia is counteracted perfectly<\/span><\/span>.<\/span><\/p>\n The Result:<\/span><\/b> Angular deviations on this
