Precision Round Bar Straightening & Burnishing Machines

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.

Product Description

Precision Round Bar Straightening machine:

Two-roll straightening machine: straightening bars or tubes by a pair of concave and convex tool steel roller, the bar/tube can get the straightness and polish by passing through two rollers. Two roll rotary straightening is a cold finishing mill process. For extremely close tolerances, rotary and roll straightening may be followed by press straightening. Variations in the distance between roll centers and the amount of offset adjust the degree of the bend according to section size and the yield strength of the material. BAOTE can make a precision round bar straightening machine according to the customer’s request.


Working principle of precision round bar straightening machine:

Curved metal rod has different bending curvature, bending size, and bending direction. A two-roll bar straightening machine can eliminate the non-uniformity of curvature by repeating bending metal bars and make metal rods straight.

Small deformation correction program is that the upper straightening roll can be adjusted and the reduction is the principle of adjustment. The metal into the roll through the bending and bending after the spring back, its maximum original curvature should be completely eliminated, that is, the part can be straight.

The pressure of the straightening roller: The pressure acting on the straightening roller at the time of straightening can be calculated using the bending moment required by the metal being straightened, and the metal is considered as a continuous beam subject to a large number of concentrated loads. The transmission power of the two-roll bar straightening machine is related to torque and curvature.

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.
