This machine tool is designed and manufactured using the latest technology from the Belgian company DERATECH, ensuring its strength, rigidity, and safety. The machine tool has a simple and beautiful appearance, exquisite workmanship, and the mechanical processing and assembly of components are all meticulously crafted. The machine adopts an overall high-quality steel plate welding structure, with a thick and rigid frame. The surface of the machine is sprayed with imported anti rust primer and topcoat to make it last as good as new. The rack and upper working slider are processed by precision mother machines such as imported large-scale CNC floor boring and milling, ensuring the positional accuracy requirements of each installation surface.

This machine tool is mainly composed of a frame, an upper sliding plate, a rear material blocking system, a sliding block and synchronous control device, a mold, a hydraulic system, a control system, etc

1. Rack section: This component is a frame shaped structure, consisting of workbench vertical plates, left and right side plates, connecting beams, mechanical compensation devices, etc. The steel plate is welded as a whole, with good rigidity, high strength, and excellent resistance to twisting and deformation; And internal stress is eliminated through surface shot peening and other processes, ensuring the long-term stability of the overall accuracy of the machine tool; During bending, the deformation of the skateboard and worktable is small, ensuring excellent straightness and angular consistency of the workpiece.

2. Skateboard part: The left and right oil cylinders are fastened to the frame with bolts, and the piston rod of the oil cylinder is connected to the slider with spherical pads and screws. This structure improves the working state of the piston rod and the bonding performance between the piston rod and the slider when the slider is subjected to eccentric loads; The slider and the frame are connected by a rectangular guide rail pair with self-lubricating function; A grating ruler with a measurement accuracy of 0.005 mm is installed on the C-shaped plates on both sides of the rack to detect and feedback the synchronous motion status of two oil cylinders, in order to control the stroke position of the slider.

3. Mechanical compensation device: When bending sheet metal, the upper sliding plate inevitably undergoes bending deformation, resulting in the bending angle of the workpiece being small at both ends and large in the middle. This machine tool is equipped with compensating wedge iron and controlled by a CNC numerical control system to generate pre convex compensation for the deflection deformation of the upper sliding plate on the lower worktable, controlling the angle change of the workpiece within the allowable range and ensuring high-quality bending accuracy.

4. Mold and clamping device: The mold consists of an upper mold and a lower mold, which are quenched as a whole and durable. The upper mold is installed on the slider and fixed by the quick clamping device of the pressure plate. The lower mold adopts a concentric mold form, which is convenient and fast to change, reduces labor intensity, and improves production efficiency.

5. Front material support bracket: This component is a standard part and is installed on the front of the workbench. When in use, the material support bracket can be manually moved to the appropriate position and tightened according to the length of the workpiece. The material support bracket can be adjusted in both horizontal and vertical directions.

6. Special structure throat deformation compensation device: Install a grating ruler on each side of the machine tool to measure and feedback the precise distance between the slider and the lower worktable. The grating ruler is connected to the worktable through a C-shaped frame, effectively eliminating the influence of frame throat deformation on the position of the slider; The position data of the slider during operation is fed back to the numerical control system, and the output signal of the numerical control system controls the operation of the hydraulic proportional servo valve. The two sets of electro-hydraulic proportional servo valves are controlled separately to maintain precise synchronization between the two oil cylinders.

This structure can enable the machine to have anti bias load capability and effectively prevent non-standard workpieces from colliding with and interfering with the grating ruler.

7. Rear material blocking device: Adopting the latest precise and stable rear material blocking device designed in Belgium, the servo motor drives the ball screw, which has the characteristics of fast speed and high positioning accuracy; The novel and unique dual linear guide structure ensures excellent positioning accuracy; Multi level gear design, increased positioning range, value for money; Modular design, with the option to control the number of axes from single axis X to multiple axes.

8. Suspension arm system: A suspension arm system that is more ergonomic, with a reasonable rotation radius, more flexible and versatile, and easier to operate.
