Press Brake, WE67K Series

Features This press brake features a fully welded structure with a high strength and rigidity. Main components use an ANSYS FEM (Finite Element Analysis) to ensure machine reliability and accuracy. The main oil cylinders on both sides use a different control method than traditional bending machines do. This equipment uses a closed-loop control method comprised of an electro-hydraulic servo valve and grating ruler imported from Germany. The slide block features an excellent position feedback accuracy, supporting stable operation. The slide block bending angle and position are both recorded to ensure uniformity. Functional parts in the back gauge are all imported to ensure the accuracy. We also use a multi-axis back gauge to improve the gauging precision according to customer needs. The hydraulic system uses an integrated control system imported from Germany. It features a simple design, reducing the number of pipelines needed for operational stability. High-precision grating scales are installed on the C frame on both sides, therefore preventing any influence on the bending accuracy caused by deformation. The worktable supports hydraulic deflection compensation, allowing for an effective compensation for operational stability. The numerical control systems on the electro-hydraulic bending machines are imported from Italian ESA, Dutch DEL EM or Swiss CYBELEC, allowing for a number of functions, including bending angle programming and auto-correction, bending pressure adjustment, back gauge retraction and more.
