4000 mm 250-ton Hydraulic Press Brake with CT8

250-ton Hydraulic Press Brake with CT8, 4000 mm CNC steel bending machines for sale. The bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a worktable and a clamping plate. The worktable is placed on the bracket. The worktable is composed of a base and a pressure plate. The base is composed of a seat shell, a coil and a cover plate, the coil is placed in a recess of the seat shell, and the top of the recess is covered with a cover plate. When in use, the coil is energized by the wire, and after the electricity is energized, a gravitational force is generated on the pressure plate, so as to realize the clamping of the thin plate between the pressure plate and the base. Due to the use of electromagnetic force clamping, the pressing plate can be made into various workpiece requirements, and the workpiece with side walls can be processed, and the operation is also very simple.

Introduction of CNC bending machine

The bending machine is to use the equipped mold (general or special mold) to bend the cold metal sheet into workpieces with various geometric cross-section shapes. The bending machine generally adopts a special CNC system for the bending machine. The coordinates of the bending machine The axis has been developed from a single axis to 12 axes, and the CNC system can automatically realize the sliding depth control, the left and right tilt adjustment of the slider, the front and rear adjustment of the rear stopper, the left and right adjustment, the pressure tonnage adjustment and the slider approaching working speed adjustment, etc. . The bending machine can easily realize the actions of the slider downward, jog, continuous, pressure maintaining, return and stop in the middle, and complete the bending of multiple elbows with the same angle or different angles at one time.

● The whole welded machine structure achieves high rigidity; the machine is designed by ANSYS software which can ensure the reliability and precision of the press brake.

●  The servo motors for back-gauge and ram stroke are controlled by servo driver, which can achieve high positioning accuracy of the back-gauge and can work with high speed.

●  X axis (Back-gauge) and Y axis (Ram stroke or cylinder stroke) can be programmed by the controller, which can set the bending angle directly.

●  Side and rear metal safety guard meets European safety standard.

●  The back-gauge will be equipped with linear guide and ball screw. 

●  Hydraulic overload can be protected by overflow valve, System pressure can be regulated by pressure switch easily.

●  Foot switch with emergency button can stop the machine immediately when accident happens.
