Bar Straightening Machine

The automatic bar straightening machine is used for straightening steel bars (hot rolled or forged). The height-adjustable two-roll straighteners have a fixed bottom roll and an adjustable top roll. The adjustments are carried out by motor. The adjustable components are hydraulically clamped. To compensate for the unroundness existing in black material and the given rolling tolerances, the top roll has a hydraulic bearing. This will prevent machine damage. In addition, the introduced straightening force can be precisely directed and controlled. BAOTE automatic bar straighteners correct shape defects in carbon, alloy, titanium, aluminum, platinum, silver, stainless steel, copper, and brass bars. The automatic bar straightening machine processes not only round bars but are also used to burnish and size bars, as well as de-rod materials for tubes.

BAOTE two-roll two-motor bar straightener offers customers with space constraints a viable solution to process larger diameter material due to its compact footprint with the motors being mounted directly on the machine. Performing well in both black bar and burnishing applications, this machine is a versatile option to the vertical over/under straighteners in larger diameter applications. The two roll straightener straightens materials of different diameters through the angle change of two rollers. The two roll bar straightener can be used for the diameter range 10 to 160 mm. BAOTE provides purpose-built solutions to fit each customer’s specific needs and applications. Contact us for more information.

Precision round bar straightening machines are of the two rolls adjustable angle type. The bar straightening machine can be customized to suit customers' needs. BAOTE two-rolls bar straightening machine consists of two-beams and four-columns structure, prestressed structure, and frame structure. Two-roll bar straightener usually used to straight high yield strength and small bending metal bars and rods and achieve high straightness and good surface roughness.

Steel bar straightener can be implemented in rolling mill finishing lines, inspection lines, or individual straightening lines. In straightening lines, the straightened material is transported to straightening machines by means of conveyors, or troughs, situated at the input and output. The steel straightening machine is mainly used for precision straightening for the metal bar after peeling or grinding and pre-straightening for the metal bar. The machine adopts a special curve between upper concave and the lower convex two straightening rolls to realize calendering and straightening at the same time, which greatly improved the working efficiency.

The wire straightening machines are assigned for continuous straightening of wire from wire coil, which is afterward measured and cut to the desired length. BAOTE wire straightening machine is designed as stand-alone lines for the high-speed production of straightened and cut wire. These machines are robustly designed and are offered with a range of different payoff options (DIN or Motorised Rotating Platforms) to suit the presentation of the wire. The wire is driven by a series of feed wheels through the dual spinner assemblies and is cut to length in a high speed flying shear. The shear is designed to give a flush, square end cut at maximum operating speed. Gearing between the feed and spinner drives ensures a constant straightening angle under all conditions to provide optimal straightness of the finished wires.

The round bar straightening machine is made of alloyed chrome steel. They are forged from one piece, raw machined, hardened, and finished or ground. The rod straightener has a fixed bottom roll and an adjustable top roll. The operator has either preshaped handwheels or an automatic NC control to set the roller straightening machine. After entering the basic parameters, the controller calculates the optimal configuration of the machine.

Round bar straightening machine is used for straightening and polishing bars made of steel (drawn or peeled) and non-ferrous metals (cast, extruded, or drawn). The adjustments of the steel bar straightening machine are carried out by motor. The adjustable components are hydraulically clamped. To compensate for the unroundness existing in black material and the given rolling tolerances, the top roll has a hydraulic bearing. This will prevent machine damage. In addition, the introduced straightening force can be precisely directed and controlled.

Two-roll round bar straightener is the equipment for straightening bars, pipes, and wires. The straightener changes the straightness by extruding the bar with the straightening roller. The two-roll bar straightening machine is the workhorse of the BAOTE product line excelling in both straightening and brushing applications. The over/under Roll design allows for quick roll and guide changeovers. Motor horsepower determination is dependent on the speed requirements and the materials to be processed.
