Машина для формовки коробочных балок

A box beam roll forming machine is a heavy-duty industrial production line that continuously unrolls, levels, punches, and shapes flat metal coils into closed, hollow rectangular or square profiles, commonly referred to as box beams.

The most common application for these profiles is in the material handling industry, specifically as the horizontal, load-bearing crossbeams in pallet racking systems. They are also widely used in structural framing, construction, and heavy-duty shelving.

Forming a closed box requires the edges of the metal strip to be joined together. Machines typically accomplish this using one of two methods:

• Interlocking (Clinching): The machine rolls the edges into a specific lip-and-groove profile and then uses heavy pressure rollers to fold and lock them together into a tight mechanical seam.

• Welding: The line is equipped with an integrated High-Frequency (HF) induction welder or a continuous seam welder that permanently fuses the two edges as they meet, creating a solid, seamless tube.

Because box beams must support massive amounts of weight, these machines are built to handle high-yield carbon steel, cold-rolled steel, and galvanized steel. The typical material thickness ranges from 1,5 мм до 3,0 мм (approx. 16 to 11 gauge).

Yes. Since racking systems require beams of varying heights and widths (e.g., 80mm to 160mm heights), these machines are highly adjustable. They are often built as duplex roll formers, meaning one side of the roller stands is mounted on a movable base. The operator can use a motorized system to widen or narrow the distance between the rollers to produce different beam sizes without having to remove and replace all the tooling.

Most box beam lines incorporate an inline hydraulic punching station located between the uncoiler/leveler and the roll forming section. This station automatically punches the required safety pin holes or connector slots into the flat steel strip before it is folded into a box.

Standard production speeds generally range from 10 to 20 meters per minute (approx. 33 to 65 feet per minute). The exact speed depends heavily on the thickness of the steel, the frequency of the punching required, and the method used to close the beam (welding vs. interlocking).

Cutting a thick-walled, hollow profile requires a specialized, heavy-duty mechanism. These machines utilize a hydraulic flying shear or a tracking cutter equipped with a custom-machined, multi-piece cutting die. The die securely clamps the outside of the box while a blade shears through the metal, ensuring a clean cut with absolutely no deformation or crushing of the hollow ends.

The return on investment for the профилегибочная машина для коробчатых балок depends on production volume and local market pricing, but most manufacturers see payback within 12 to 24 months. A single machine running at 15-20 m/min can produce thousands of meters of box beam per shift. For context, the starting price of a quality machine is  around $whiлеаfiniсчаседbоxbеamлвe\; canгенerате$500,000- $1,000,000+ in annual revenue depending on scale.

Installing a профилегибочная машина для коробчатых балок and commissioning typically takes 2 to 3 weeks on-site, including:

• Foundation preparation and machine leveling
• Electrical and hydraulic connection
• Trial run with sample materials
• Operator training
• Final quality inspection

Beli Rollforming includes on-site installation and commissioning in the standard package, with engineers present until the line reaches stable production.

Maintaining the профилегибочная машина для коробчатых балок is straightforward and keeps the line running at peak performance:

• Ежедневно: Visual inspection of rollers, check oil levels, clear scrap material
• Weekly: Lubricate roller bearings, inspect punch dies, check belt tension
• Monthly: Inspect roll wear, check alignment, verify hydraulic pressure
• Ежегодно: Full system overhaul, replace worn rollers, recalibrate forming stations

Сайт PLC + HMI control system logs operating data to help predict maintenance needs before failures occur.

Yes. The профилегибочная машина для коробчатых балок from Beli Rollforming offers full customization of:

• Beam dimensions: Custom heights (80-300mm), widths (50-100mm), and thicknesses (1.0-3.5mm)
• Profile geometry: Closed rectangular, square, or custom closed-section shapes
• End connectors: Custom hole patterns, bracket types, and connector geometries per MHI or OEM standards
• Seam closure: Interlocking (standard) or HF welding (optional) based on strength requirements

Custom profiles typically require a 3 to 5-week tooling lead time in addition to the standard machine delivery.
