Straightening machine is mainly used for precision straightening and calendering for the steel round bar after peeling or grinding and rough pre-straightening for the black bar. Due to calendering and straightening can be completed at the same time, so the working efficiency is high.Especially for the high speed steel round bar straightening and calendering.

Introduction of Composition
1.Main Machine
Upper and lower body respectively install a straightening roll,upper roll is concave lower roll is convex. According the diameter and the material properties of the bar, respectively to adjust upper and lower straightening rolls,start the cooling lubrication system ,driven by main motor, to complete calendering and straightening at the same time.
Frequency conversion stepless speed , real time display the gap between upper roll and lower roll. Guide sleeves are installed in the inlet and outlet. Its location can be adjusted, playing guide and support role. During processing , the bar can accurately enter and leave the straightening rolls.
2. Cooling lubricants System
Cooling lubricants by cooling pump suction, through multiple pipelines from the front spray nozzle to the roll gap and the bar, playing cooling and lubricating role. After converging, follow together into the coolant tank. Coolant tank design three layers protection filter, to ensure lubricating coolant cleaness.
3. Electrical system
The transmission system adopts frequency conversion stepless speed regulation, feeding system, adjustment system,cooling and lubricating system controled by AC power . The main power supply is AC 380V 50Hz, control power supply is AC 220V 50Hz.
Control system for low voltage power supply.
Entry Guide System and Exhaust System
The four-columns structure
Two nylon rollers clamp the workpieces and assure the workpiece not easy to slip,reliable work.
Entry Guide System
The upper and lower cylinders respectively control the upper and lower nylon rollers lifting,meanwhile , two motors drive two nylon rollers rotating .Then clamp the bars entering the entrance of the guide sleeve.
Auxiliary Machine Automatic loader and unloader, greatly saving labor cost. After
Straightening all the collection racks are equipped with protective layer to avoid any scratches.
