Introduction of Straightening Machine

 

Straightening machine is mainly used for precision straightening and calendaring for the bar after peeling or grinding and rough pre-straightening for black bar.

Due to calendaring and straightening can be completed at the same time, so the working efficiency is high.

The machine adopts special curve between upper and lower cancave and convex two straightening rolls to realize calendaring and straightening at same time.

Two-rolls Straightening Machine, includes two-beams and four-columns structure, prestressed structure and frame structure.

 

Features of Two-rolls Straightening Machine

1. Fast feeding straightening speed, it can reach 10-30 m/min.

2. Straightening and calendaring at same time.

3.High precision, straightness can reach 0.15mm/m to 0.4mm/m, surface roughness Ra0.8μm.

 

 

-Main Machine

Upper and Lower body respectively install a straightening roll, upper roll is concave, lower roll is convex.

According to the diameter and material properties of bar, respectively to adjust upper and lower straightening roll angle, electric lift part adjust gap between two straightening rolls, start the cooling lubrication system, driven by main motor, to complete calendaring and straightening  ar 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 straightening rolls.

 

-Cooling Lubrication System

Cooling lubrication by cooling pump suction, through multiple pipelines from front spray nozzle to roll gap and bar, playing cooling and lubricating role. After converging, follow together into coolant tank. Coolant tank desigh three layers protection filter, to ensure lubricating coolant cleanness.

 

-Electrical System

The transmission system adopts frequency conversion stepless speed regulation, feeding system, adjustment system, cooling and lubrication system controlled by AC power. The main power supply is AC 380V 50Hz, control power supply is AC220 50Hz. Control system for low voltage power supply(DC24V)

 

-Entry Guide System and Exhaust System

 

Exhaust System

The four-columns structure

Two nylon rollers clamp the workpiece and assure the workpiece not easy to slip, reliable work.

Entry Guide System

The upper and lower cylinders respectively control upper and lower nylon rollers lifting, meanwhile tow motors drive two nylon rollers rotating. Then clamp the bars entering entrance of 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.
