Two-roll Steel Round Bar Straightener

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.

Product Description

Two-roll Steel Round Bar Straightener:

BAOTE sells two-roll bar straighteners that can be used to correct the shape of a bar, pipe, tubes, and round products. The material to be straightened may be carbon steel, stainless steel, copper, brass, or aluminum. BAOTE two-roll bar straightening machine allows us to straighten bars from1/8” diameter to 12” diameter. 


The principle of bar straightener

The principle of press straightening is illustrated below. The bar to be straightened is supported by press blocks (A), with the convex side of the bow or kink being directly under the hydraulic ram (B). Sufficient force is applied by the hydraulic ram to cause the bar to become bowed in the opposite direction, in effect straightening the bar. Deviation from straightness in round bars may be expressed either as a camber (deviation from a straight line) or as total indicator reading (TIR) per unit of length.

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.
