Five, the machine structure characteristics

The frame adopts steel plate overall welding structure, good rigidity, high strength, good resistance to distortion and deformation, and through the surface shot peening process to eliminate internal stress, to ensure the lasting stability of the overall accuracy of the machine tool. When bending slider, table deformation is small, the workpiece has excellent straightness and Angle consistency.

Pieces by Germany BOSCH company bending machine dedicated digital closed loop hydraulic system (electric liquid proportion servo synchronization control system), the system is a kind of position control system, it through the grating ruler to dynamically detect the slider synchronization error, by numerical control system of electrohydraulic servo valve synchronization error correcting slide block, make the slider in the case of partial load have always been able to keep in parallel with the workbench. Slider synchronization accuracy ≤±0.02mm.

◆Y1, Y2 axis -- the left and right sides of the slider are equipped with Haidhan high precision grating ruler (Y1-Y2), they are used to determine the exact distance between the slider and the workbench, the accurate position data of the grating ruler installed on the bow frame can be fed back to the NUMERICAL control system, it can calculate the output servo valve control signal (S1-S2). Thus, the positioning accuracy of the slider is ≤±0.02mm, and the repeating positioning accuracy of the slider is ≤±0.01mm.

◆X axis is the rear stopper control axis, the rear stopper device adopts servo motor and precision ball screw and square linear guide rail, so that the positioning accuracy of X axis transmission is less than or equal to ±0.1mm. The two blocks in motion always keep synchronized, to ensure the accuracy of the workpiece.

◆R axis is the upper and lower control axis of rear stopper. The rear stopper device is supported by servo motor and precision ball screw and front and rear guide rail, so that the upper and lower positioning accuracy of R axis is less than or equal to ±0.1mm. Make the rear stopper up and down to keep synchronized, to ensure the accuracy of the workpiece.

◆ In order to ensure good machining accuracy of the workpiece, the original WILA company produces the inclined wedge type mechanical deflection table compensation mechanism: WILA mechanical deflection compensation device is composed of a number of two convex plate with slope, they can move relative to form a cluster of ideal position convex curve, in the processing of different thickness or length of the parts can be automatically controlled by the NUMERICAL control system precise convex amount of the device, so as to ensure good accuracy of the workpiece processing. The compensation device not only has the function of CNC horizontal automatic compensation but also the function of longitudinal manual compensation adjustment.

◆ The main components of the machine electrical control system are schneider products from France, and the main seals of the hydraulic system are imported from Europe and America.
