Perforated Steel Keel
This perforated steel keel machine belongs to Light Gauge Steel Roll Forming Machine series, integrated cold bending equipment with on-line punching function. It completes steel strip punching, bending forming and fixed-length cutting in one continuous pass, producing perforated drywall & ceiling light steel studs and tracks (C-stud, U-track, cross ceiling keel). Perforated keels allow easy cable threading and fast screw fixing, widely used for gypsum partition walls and ceiling frames in hotels, office buildings, residential decoration and prefabricated buildings.
The machine base is integrally welded with thick square tubes and stress-relieved by annealing after welding to eliminate deformation stress. Punching and forming stations run synchronously without vibration, punching hole diameter and keel cross-section dimension digitally adjustable. All forming rollers are precision turned 45# steel with hard chrome plating after quenching for excellent wear & rust resistance, processing hot-dip galvanized strips 0.5–1.2mm thick. Front hydraulic punching die unit stamps multi-size holes in one stroke, followed by multi-stage progressive bending roller stands to fully form keel profiles, burr-free sheet surface without spring-back deformation, tight interlock for stable wall structure. Keel width, height and punching patterns can be customized on demand.
Equipped with variable frequency synchronous chain transmission, punching and forming speed are matched and linked, running smoothly with low noise, forming speed steplessly adjustable from 6 m/min to 16 m/min. Manual deviation corrector at feeding inlet easily centers steel strips to reduce edge waste. Vertical hydraulic cutting unit at tail delivers clean burr-free cuts, finished length tolerance ≤±0.8mm. PLC touch screen control system stores multiple sets of keel & punching parameter recipes, automatically completing feeding, on-line punching, roll forming, fixed-length cutting and yield counting. Only one operator can realize 24-hour non-stop continuous production.
Every perforated keel forming machine undergoes a 72-hour synchronous punching & forming endurance test before delivery to calibrate hole position precision, keel cross-section and cutting tolerance. Punching dies, forming rollers, cutting blades, hydraulic sealing parts and bilingual operation manuals are supplied as standard accessories. Xinnuo offers a 2-year full machine warranty, industrial voltage customization available for all countries, delivery lead time 50–60 days. Remote installation & debugging guidance is accessible for overseas buyers. This all-in-one punching keel equipment receives consistent orders from light steel building material manufacturers worldwide.
