Electro-hydraulic servo CNC bending machine(Press brake)

Rack use american ansys and ugs/cad/cae/cam 3 d softwarefor finite element analysis and optimization design to ensurethe strength and structure of the rack.
Full steel plate overall welding, strong seismic resistance.The complete machine annealing eliminates the stress andhas good stability.
Compensates with electric machinery with high bendingaccuracy.
The frame, slider, rear retaining beam and housing shall beadded by the european imported penttahedral processingcenter.
Work forming ensures the parallelism and verticality of eachinstallation surface.
Nominal pressure: 1000KN
Length of workbench: 3200mm
Throat depth: 300-600mm

Product Description
The whole welded structure has strong seismic resistance.
The slider position feedback accuracy is high, the operation is accurate and stable, the synchronization performance is good, the bending accuracy, and the slider repeat positioning accuracy are high.
The backgauge function is more complete, with multiple backgauge shafts.
The integrated hydraulic control system ensures the stability of the machine tool.
The hydraulic deflection automatic compensation mechanism eliminates the influence of the deformation of the slider on the quality of the workpiece.
