Series JY straightening machine is mainly used for precision straightening for the metal bar after peeling or granding and pre-straightening for the metal bar.
The machine adopted special curve between upper concave and the lower convex two straightening rolls to realize calendering and straightening at the same time,which greatly improved the working efficiency.
Series JY two-rolls Straightening Machine consists of two-beams and four-columns structure,prestressed structure and frame structure.
1.Fast feeding and straightening speed,which can reach 10-30m/min.
2.With special carves ,it can straighten and calender materials at the same time.
3.High precision.straighteness can be 0.15-0.4mm/m,surface roughness Ra≤0.8μm.
The upper and lower body respectively install a straightening roller,the upper roller is concave ,the lower roller is convex.
According to the diameter and the material properties of the bar,respectively to adjust upper and lower straightening roller angle,electric lift part adjust the gap between the two straightening rolls,start the cooling lubrication system,driven by main motor,to complete calenderingand straightening at the same time.
Cooling Lubrication System
Cooling lubrications by cooling pump suction,through multiple pipelines from the front spray mozzle to the roll gap and the bar,playing cooling and lubricationing role.After converging,follow together into the coolant tank.Coolant tank design three layer protection filter,to ensure lubricating coolant cleaness.
The transmission system adopts frequency conversion stepless speed regulation,feeding system,adjustment system,cooling and lubricating system controled by AC power.
Entry Guide System and Exhaust 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.
Two nylon rollers clamp the workpieces and asssure the workpiece not easy to slip,reliable work.
Automatic loader and unloader,greatly saving labor cost.
After straightening,all the collection racks are equiped with protective layer to avoid any scratches.
