Machine structure characteristics and standard configuration

The frame is welded in steel, eliminating internal stress by normalizing and high frequency vibration, guaranteeing the overall accuracy of the machine tool, having the best rigidity, excellent anti-twisting and anti-tilting ability. Thicker workbench plate and thicker slider make the machine very rigid. Therefore, when bending, the deformation of slider and workbench is very small and the workpiece has excellent linearity and angle uniformity.

Use large floor boring-milling machine and one-time machining method after integral welding to make precision machining to ensure machining accuracy.

Technical characteristics of equipment of Hydraulic Press Brake

The special hydraulic system (electro-hydraulic proportional servo synchronization control system) of Rexroth bending machine in Germany is adopted. The system is a position control system, closed loop type. It dynamically detects the synchronization error of the slide block through the grating ruler. The electro-hydraulic servo valve of the numerical control system corrects the synchronization error of the slide block, so that the slide block can always keep parallel with the workbench under the condition of complete partial load. The synchronous accuracy of sliding block is ≤±0.02mm.

The numerical control system controls the opening size of the proportional valve, and the proportional valve regulates the oil inlet of the left and right oil cylinders. The Y1 and Y2 axes -- the left and right sides of the slide block are respectively equipped with the GIVI high-precision linear grating scale (Y1-Y2) of the European ATEK company, which is used to measure the exact distance between the slide block and the workbench. The grating scale and the column are soft connected, and the column deformation will not affect the positioning. The position data is immediately fed back to the CNC system, which can calculate the output servo valve control signal (S1-S2). Thus, the positioning accuracy of slider is ≤±0.02mm.
