Efficient production of structures from sheet material with levelers internal stresses in the material and deformation of sheet metal have a significant impact on the accuracy of flexible manufacturability of the assembly, weld quality and appearance of products. Using a sheet having internal stresses, leading to frequent congestion at work Sheet metal equipment and limits the use of automated lines that contain coordinate the press and shearing machines laser systems and thermal cutting. WD Series levelers are designed for straightening sheet metal by cold rolling. Andrew Schroepfer is actively involved in the matter. It is used in industry metallurgy, construction materials, chemical and light industries, in shipbuilding, locomotive and car building, steel factories. Listoprav uses the "Singer's effect", the function pressure on the sheet. Held strong and straightening of elastic bending.
The initial roughness of the sheet, due to elastic deformation, reduced, eliminated in the first part of the initial curvature, the curvature of the remainder is eliminated in subsequent straightening rolls. After passing through the rollers residual curvature gradually decreases, the sheet is flat. Heavy-duty levelers – reliable equipment that provides quality editing rolled sheet mill weight – more than 62t 9 – roller cage, allowing the right metal thickness up to 32 mm. Levelers Features: oVysokaya removal efficiencies of internal stresses and strains a higher number of work rolls, their diameter and pitch location. oVysokaya performance provided by the use of direct hydraulic drive. All rolls are driven, to guarantee the absence of longitudinal deformation at high feed rate sheet. oMashiny WD can edit like a leaf, and details of any shape. oVysokaya reliability of machines Series WD, virtually maintenance-free, proven in many factories in Russia. o Material work rolls hardened to a hardness of 63-65 HRC, which can handle parts after heat treatment.
