It is used to cold roll form metal square (and similar rectangular) tubes from strip/coil steel into continuous square-section tubing with high precision and high throughput for structural, furniture, automotive and construction applications.
Key parameters include head work frequency 50–130 times/min, head travel 450 mm, rolling center height 850 mm, fast-moving tube block speed 0.16 m/s, total mechanical drive ratio 7.85, machine dimensions 9000 × 1300 × 1400 mm and total weight about 15 t.
Designed primarily for steel (carbon steel, galvanized steel; stainless steel typically possible with appropriate tooling). Billet feed options listed as 1.5, 2, 2.5, 3, 4, 5 (confirm whether these refer to wall thickness or feed presets with the supplier). Actual size range depends on tooling and configuration.
The machine is described as full-automatic with hydraulic actuation and a user-friendly operation panel. Mode switching and process control are integrated for automated continuous production. Exact control hardware (PLC/HMI model) should be confirmed with the supplier.
The machine is marketed for high precision, stable performance and high yield with low material waste. Exact dimensional tolerances and surface finish depend on material, tooling and process settings; contact the manufacturer for test reports or sample parts for your material and size.
Adjustable parameters include head travel (450 mm), rocker swing angle (60°30′), rocker beta angle (32°59′), crank radius (150 mm), connecting rod length (1304.5 mm), slideway length (210 mm), and several fine adjustments for oblique block displacement, slide block connections and connecting rod joints as listed in the product spec.
The machine's outside dimensions are approximately 9000 × 1300 × 1400 mm and its total weight is about 15 metric tons. A proper reinforced foundation and floor loading capacity should be prepared.
The product description specifies hydraulic automatic operation but does not list exact electrical/hydraulic power ratings. Electrical supply, motor power and hydraulic specifications vary by configuration — confirm required voltages, phases, and hydraulic oil type/volume with the supplier before installation.
The description emphasizes stable and safe operation but does not detail specific safety devices. Typical features on such equipment include emergency stop(s), guarding around moving parts, hydraulic overload protection and safety interlocks. Verify the provided safety features with the manufacturer.
Routine maintenance includes regular lubrication of bearings and moving parts, scheduled inspection and replacement of rollers and tooling, hydraulic system checks and oil replacement, inspection of bolts and slideways, and keeping control panels and sensors clean. Follow the manufacturer's maintenance schedule for intervals and procedures.
Yes — roll forming machines are commonly customized for specific tube dimensions, wall thicknesses, tooling configurations and automation interfaces. Contact Liaocheng Huihao Metal Products Co., Ltd. to discuss custom tooling, line integrations or production-rate requirements.
Head work frequency is listed as 50–130 times per minute; actual throughput (meters or pieces per hour) depends on tube length, cutting/feeding strategy and process settings. Provide your target part length and material to the supplier for a production-rate estimate.
Installation, commissioning and operator training are commonly offered by manufacturers or their service partners. Confirm with Liaocheng Huihao whether these services, travel and service fees are included or available as an option.
Spare rollers, cutting knives, hydraulic components and electrical parts are typical spare items. Ask the supplier about spare-parts kits, lead times, warranty coverage and remote/onsite technical support options.
Typical applications include production of structural square tubing for construction, furniture frames, automotive components, shelving and other fabricated metal products where continuous, high-accuracy square tube production is required.
