1. The transmission device is the same as the frequency converter (circulation control) and can be synchronized with the punching machine for balanced feeding. Two-stage leveling. During the coil leveling process, (both ends-tail end), there is no need to adjust the leveling in the middle, which can ensure the same flatness. Due to the different curvatures of the materials, a single straightening roll arrangement can

Work-piece will get out of shape at stamping process, especially at piercing hole edge, trimming area, forming area etc. as the equilibrium of tension and compression was broken at these areas. In laser cut process, work-pieces get out of shape because of high temperature process cause breaking inner stress. So it will surely influence the following process of bending, welding etc. process if don’t do work-piec

Four-high roller leveling machine adopts adding supporting bearings (rollers) at both upper and lower leveling rolls set, forming upper double layer roller set+ lower double layer roller set total four-layer structure. It’s the same to six-high roller leveling machine: upper three layer roller set+ lower three layer roller set total six-layer structure. The principle of leveling process: metal sheet was repeate
