Seven Roll Bar Straightening Machine

We are engaged in manufacturing, supplying and exporting Seven Roll Bar Straightening Machine to our clients.

Machine Description:
Mainly comprised of a straightening machine, loading and unloading tables, electric control, and hydraulic, pneumatic and lubrication devices, RG vertical straightening machines with multiple (mainly seven) rolls can effectively eliminate bending at two ends, slight out-of-roundness, and oxide scales.
Advantages:
1. Adopt optimized quasi-double curve and deep/shallow concave (evolved from convex and concave roll) shape complex rolling system, absorb the advantages of straightener with two-roll and traditional multiple skew rolls, and overcome both shortcomings, so the straightening precision is higher.
2. Adopt the principle of double rolls pressing with controllable load, turn rigid frame into flexible one, and ensure necessary pressure on bar, thus expand the scope of bar plastic area, which can improve the straightening precision and protect mechanical equipments from damages.
3. Main transmission adopts SIMENSa s full-digital DC (or AC) gear, step-less speed, constant torque output under basic speed and constant power output above basic speed.
