Precious 4-high roller leveler machine by manual
This is semi-automatic & economic type 4-high roller leveling machine, roller gap adjusted by manual in the guidance of digital display, so operator can crank the two hand wheels to adjust leveler’s straightening performance.
4-high roller leveling machine process principle
It’s based on “Bauschinger effect”, metal sheet was repeatedly twisted to make metal fiber gradually consistent, eliminate internal stress, restore and improve the flatness of work-pieces. So as to get ready for the subsequent process such as bending, welding and other processing procedures.
steel plate leveling machine
Machine main feature
- It's four-high roller level precious leveling machine, there are both support assistant roller set upper and lower leveling roller set. All rollers were well processed to ensure leveling accuracy.
- All leveling rollers adopt high quality bearing steel, finished quenching and tempering, precious machining, hard chrome plating, grinding etc. Surface hardness comes 58±2°(chrome layer thickness ≥0.05mm)
- All backup roller(support roller) adopt Japan export roller bearings. There are 2 columns or more columns backup rollers uniformly distributed upper and lower leveling roller sets, making leveling rollers bears pressure in balance.
- All gears adopt material of 20CrMnTi, finished forging, tempering, surface carburization, precious grinding etc. coming to grade IT6.
- Main bearings are Shielded and sealed NSK bearing made in JAPAN, it can well reserve itself stocked lubrication oil and prevent dust enters, so it doesn’t need to add lubrication oil on bearings.
- Roller gap adjusted by manual in the guidance of digital display, so operator can crank the two hand wheels to adjust leveler’s straightening performance.
- Main power transmission method: AC motor+ speed reducer+ universal joints, so machine runs smoothly.
- High precision and perfect working performance.
