Automatic 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.

Product Description

Automatic Bar Straightening Machine:

The automatic bar straightening machine is used for straightening & polishing of peeling bar or drawn bar. This machine is part of a bright bar production line for bar diameter up to 80 mm, comprising a heavy-duty bar peeling machine, a straightening/polishing machine, and a facing and chamfering unit. The line is complemented by a testing line and a laser marking device. The special curve between the upper concave and the lower convex of the two straightening rolls can easily realize calendering while straightening. 

BAOTE automatic bar straightener considerably improves surface finish and removes any band in this bar. Our automatic bar straightening machines are used for precision straightening of round bars. It is used for straightening and calendering various metal bar after peeling or grinding. The hydraulic clamping of the adjusting axes and the compact and torsion-proof design facilitates that the highest quality requirements can be kept. We are a prominent round bar straightening machine manufacturer, offering an automatic bar straightening machine with a diameter range of 10 to 160 mm.

Design Features of Automatic Bar Straightening Machine:

  • Robust compact construction.

  • Through hardened and grinded high carbon high chrome steel rolls.

  • Rolls specially profiled to provide precision straightening of materials.

  • Gears of alloy steel.

  • Independent drives to each roll.                                                                                       

  • Precise adjustments of rolls angle with punched readout.                          

  • Adjustable guide bars.

  • All machines equipped with roll lubrication and roll coolant recirculation system.

Advantages

1. High Quality

With reference to German technology, on this basis, we update and improve our technology, compared with foreign equipment, our equipment has high quality, high efficiency, simple operation, convenient maintenance, low failure rate, low energy consumption and reasonable price.


2. Enough experience and High technology

We start from the processing industry, using self-made equipment to undertake the national bar material processing business. This is also an important basis in which we can continuously improve our equipment technology. Because we have processed different materials and specifications bar materials, we have more practical experience to suggest. Therefore, we all have better and more accurate judgment and guidance on the possible faults and operational errors of the equipment.


3. on-line tool adjustment without stopping

Compared with similar products in China, our peeling machine can make on-line tool adjustment without stopping. And we equipped with good quality accessories.
