Two roll straightening machine

The main processing part of the host machine is frame structure. A straightening roller is installed on the upper and lower body respectively. The upper roller is a concave roller and the lower roller is a convex roller. The frame prestressed straightener uses the upper body fixed, only the upper straightener roll up and down (through worm gear and worm system) to adjust the gap value of the upper and lower straightener rolls. The frame structure makes the lower body of the straightener connected as a rigid whole, which is stronger, stronger and more stable than other structures. At the top of the body on the increase in pneumatic or hydraulic tensioning system, straightening machine is working, the tension system startup, lift up on the straightening roll system, eliminate internal clearance straightening machine, even different parts within the straightener for work wear a gap for a long time, the system can completely eliminate the gap, the straightening machine in the life cycle always maintain high straightening accuracy. The STRAIGHTENING MACHINE equipped WITH HYDRAULIC protection device is equipped with constant pressure protection device, which can protect the straightening roller from overload damage when straightening the black bar material with large diameter change. According to the diameter of the material and material characteristics, respectively adjust the Angle of the upper and lower straightening roller, electric lifting part to adjust the gap between the two rollers. Start the cooling and lubrication system, and under the drive of the main drive, complete the pressing and straightening of the full length range of the material at one time.
