WE67K electro hydraulic synchronous CNC bending machine

Product description

The machine adopts Belgian DERATECH company's latest technology design and manufacture to ensure the strength, rigidity and safety of the machine. The machine is of simple and beautiful appearance, exquisite workmanship, machining and assembly of parts. The machine adopts the overall quality steel plate welded structure, the frame is heavy and rigid, and the machine is painted with imported antirust primer and top coat to make the machine durable. The rack and upper work slider are machined by precision machine tools, such as imported large CNC Floor milling, etc., to ensure the location requirement of each mounting surface.

This machine tool is mainly composed of frame, upper slide plate, rear retaining system, slider and synchronous control device, mould, hydraulic system, control system and so on.

1. rack part: this part is a frame structure, which is composed of vertical plate, left and right side plate, coupling beam and mechanical compensation device. The steel plate is solidly welded, with good rigidity, high strength and good distortion resistance. The internal stress is eliminated by surface shot peening treatment, so as to ensure the lasting stability of the overall accuracy of the machine tool. When the bending is carried out, the upper slide plate and the worktable have small deformation to ensure that the workpiece has excellent straightness and angle consistency.

2. upper slide part: The left and right cylinders are fastened by bolts with the frame. The cylinder piston rod and the slide block are connected by a spherical pad and a screw rod. The structure enables the slide block to improve the working state of the piston rod and the binding performance of the piston rod and the slide block when bearing the partial load, and the slider and the frame are connected by a rectangular guide pair with self lubrication function; the C plate on both sides of the rack is equipped with a measuring accuracy of 0.005. The grating ruler of MM is used to detect and feedback the synchronous movement state of two cylinders, so as to control the position of the slider stroke.

3. mechanical compensation device: when bending the sheet, the upper slide plate will inevitably produce flexural deformation, so that the bending angle of the workpiece will be small in the two ends and large in the middle. This machine tool is equipped with compensation iron and controlled by CNC numerical control system, so that the lower worktable produces flexural deformation of the upper convex compensation upper slide plate, and the angle variation of the workpiece is controlled within the tolerance range, so as to ensure the high quality bending accuracy.  

4. die and clamping device: the mould is made up of two parts, the upper die and the lower die. The upper die is installed on the slide block, and is fixed by the quick clamping plate clamping device. The lower die adopts the form of concentric die, which is convenient and quick for changing mould, reducing labor intensity and improving production efficiency.

5. front support bracket: this part is a standard component, mounted on the front side of the table. When used, the bracket can be moved manually to the appropriate position according to the length of the workpiece, and the bracket can be adjusted in horizontal and vertical directions.

6. special structure throat deformation compensation device: each side of the machine tool is equipped with a grating ruler to measure and feedback the exact distance between the slider and the lower worktable. The grating ruler is connected with the worktable through the C frame, which eliminates the influence of the deformation of the throat of the rack on the position of the slider. When the slider runs, the position data is fed back to the numerical control system, and the output of the numerical control system controls the work of the hydraulic proportional servo valve. The two sets of electro-hydraulic proportional servo valves are respectively controlled to keep the two cylinders in an accurate synchronization.

This structure can make the machine have the ability of resisting partial load and effectively prevent the non-standard workpiece from interfering with the grating ruler.

7. rear stopper device: adopt Belgian latest design precise and stable backstop device, servo motor drive ball screw, has the characteristics of fast speed and high positioning accuracy; novel and unique double linear guide rail structure, ensure excellent positioning accuracy; multi level gear design, increase positioning range, value for money; modular design, control shaft number can be selected from single axis X, to multi spindle.

8. suspension arm system: more suitable for ergonomics suspension arm system, set a reasonable radius of rotation, more flexible and more convenient to operate.
