It’s com

mon daily life tools of table knives, scissors, kitchen knives etc. We all know the blades were stamped by punching machine and stamping dies. It requires very flat of blade surface for these tools, but it will get a little out of shape of the blade after blanked. So how to make it to be flat?

It can be processed by the precision leveling machine for tool steel. It equips with 19pcs leveling rollers (upper 9pcs/lower 10pcs), moreover, it equips with a few groups of backup rollers both upper and lower leveling rollers, they are staggered each other for the leveling rollers and backup rollers, refer to the following image. It can make the leveling rollers stronger of the backup rollers, moreover, it can press the leveling rollers in balance as the back up rollers were arranged symmetrically.
 
● By balancing internal stress, restoring and improving metal parts flatness, flatness accuracy can reach micron grade, then it can provide qualified work-pieces for next process step of bending, welding etc.
● Roller leveler machine equip with a large number of leveling rollers arranged in multi-layers and a very small spacing between each other, then based on "Bauschinger effect", sheet metal was repeatedly
twisted to make metal fiber gradually consistent, eliminate internal stress, restore and improve the flatness.
● The stagger arranged support rollers ensure leveling rollers bearing heavy pressure in balance without bending deformation, keeping the whole equipment have enough rigidity. Upper and lower support
roller column & upper and lower leveling roller group making up four-high layers structure, ensuring stable, efficient and high-quality leveling performance.
● Electric adjust: It adopts servo motor driving to adjust leveling roller gap, so it’s convenient to adjust leveling performance by setting data in HMI, setting accuracy comes 0.01mm.
