Two Ribs Cold Rolling Ribbed Bar Machine

The RKM-50000T is a high-efficiency two ribs cold rolling ribbed bar machine that transforms smooth bars into high-performance ribbed steel bars through a precise rolling process. This Cold rolling line integrates cold rolling, rib rolling, straightening, cutting, and coiling functions to produce 6-14mm double-sided crescent-shaped ribbed steel bars.

Cold-rolled steel bar is a new type of high-efficiency and energy-saving steel that is widely used in industry, construction, highways, bridges, subways, dams, and other industries. It is also called a cold-rolled ribbed steel bar.

The Automatic Cold Rolled Rebar Making Machine wire guide bracket is mainly used to store and guide wires to avoid entanglement, stretching, or damage and ensure that wires can smoothly enter the next process during production. The wire feeding cage is usually made of solid steel or other durable materials and has a simple and efficient structure.

Mechanical Descaler

The 6-14mm Ribbed Bar Cold Rolling Mill descaler is a mechanical device specially used to remove rust, oxide, and iron from the surface of steel bars or other steel materials. The device effectively removes impurities on the surface of steel materials through mechanical friction, restores its smooth original surface, and provides a high-quality substrate for subsequent processing or use.

Lubrication System

Two-Ribs-Cold-Rolling-Ribbed-Bar-Machine-Lubrication-System

Lubricant Powder is placed in the lubrication system and is an indispensable auxiliary material in the drawing process of metals such as steel wire and steel bars.

  • During the metal drawing process, the lubricant Powder forms a uniform lubricating film to reduce the friction between the metal and the drawing die, thereby reducing energy consumption and equipment wear during drawing.
  • The high temperature generated during the drawing process will affect the material properties and the life of the processing equipment. The lubricant Powder can effectively absorb and dissipate heat to ensure the stability of the drawing process.
  • Lubricant Powder can cover the metal surface to prevent metal oxidation or external corrosion, reduce material surface defects, and improve the quality of the finished product.

Reducing Machine

The reducing machine can accurately draw the original round wire into an oval wire with a smaller diameter.

The reducing machine reduces its diameter and adjusts the cross-sectional shape while maintaining the mechanical properties and surface quality of the wire. The oval shape of the wire after diameter reduction helps to optimize its flow into the rib rolling system and further processing into ribbed steel bars.

Servo Flying Shear System – Precision Redefined

The servo flying shear system is the core of the Deformed Steel Bar Production Line’s high-speed production. It enables rapid and precise straightening and length cutting of double-ribbed steel bars, with an error range controlled within ±5mm. This results in higher-quality double-ribbed steel bars with clean, burr-free cuts, ensuring less material waste.

The servo motor’s fast response enables synchronous cutting, avoiding the efficiency drops caused by downtime or deceleration in traditional shearing equipment.

Compared to traditional hydraulic or mechanical shearing systems, the servo flying shear consumes less energy.

The fully automatic control system allows for quick switching between different cutting lengths simply by adjusting parameters on the touchscreen, enhancing production flexibility.

Two Ribs Cold Rolling Ribbed Bar Machine FAQ

The two ribs cold rolling ribbed bar machine is a device specially used for processing two ribbed steel bars. It is used to roll the steel bar surface to form a crescent shape to improve the bonding between the steel bar and concrete, thereby enhancing the stability of the building structure.

Processing on the surface of the steel bar to form a crescent shape.
Straightening and cutting the steel bar to a fixed length, or forming a coiled steel bar.
Improving the tensile strength and adhesion of the steel bar.
Mainly used for steel bar production in construction projects, such as steel bar processing required for bridges, tunnels, high-rise buildings, and other projects.
Suitable for processing light round steel bars or low-carbon steel bars of different specifications.

The ribbed steel bar machine applies pressure to the steel bar through a set of rolling dies (rollers with ribs) to produce crescent-shaped patterns on the surface of the steel bar, straighten and cut into steel bars according to customer requirements, or form coiled steel bars.

Strong bonding with concrete: the ribbed design can significantly improve the anchoring performance of the steel bar.
High tensile strength: The tensile strength of the processed steel bars is about 30% higher than that of ordinary round steel bars.
Excellent anti-slip performance: Suitable for various concrete structure projects.

Regularly replace the rolling mold to ensure processing accuracy.
Adjust the appropriate rolling pressure to avoid over- or under-processing.
Use raw materials (round steel bars) that meet the standards.
After processing, spot-check the steel bars to test the rib depth and tensile strength.
