This machine with hydraulic up-driving system can run stably. When the nominal force is less then 800kN and the worktable length is less then 3,200mm, it will adopt double cylinders. Both mechanical stop controlling the stroke of sliding block and the back gauge can be adjusted manually with digital read-out device.
When the nominal force is more then 1,000kN and the worktable length is more then 3,200mm, it will adopt three cylinders. Both mechanical stop controlling the stroke of sliding block and the back gauge can be adjusted mechanically with digital read-out device and also can be micro-adjusted by hand. To ensure the bending precision of workpiece, there is bevel joint type precision-regulating mechanism on the upper die sets.
