DX-PB-125T/2500 Electro Servo CNC Plate Press Brake Bending Machine

Electro-hydraulic servo CNC plate press brake bending machine is mainly used for bending various metal materials, users only need to be equipped with a variety of molds to bend the plate into various shapes of workpieces. This machine is equipped with a DE-15 CNC system, adopting an all-steel welding structure, and vibration aging technology to eliminate internal stress, high strength, and good rigidity.

Adopting hydraulic transmission, it works smoothly and is easy to operate, ensuring high geometric accuracy over the entire bending length. It is suitable for aircraft, shipbuilding, automobile, electrical appliances, construction, decoration, and other industries as well as the production of light poles.

Main Features of Electro-Hydraulic Servo CNC Plate Press Brake Bending Machine

  1. The machine body adopts an integral welding and integral processing structure, which ensures the reliability of the machine and the accuracy of the entire machine.
  2. The main oil cylinders installed on both sides adopt a closed-loop control method composed of German electro-hydraulic servo valves and imported grating rulers. This breaks through the traditional mechanical stroke control mode, ensuring high bending accuracy and high repeatability of the slider positioning accuracy.
  3. All functional parts installed afterward are imported, ensuring stopping accuracy. The machine can also adopt more functional multi-axis blocking according to customer requirements.
  4. The DE-15 CNC system of German Alpha Company is adopted, which reduces the installation of pipelines and ensures the working stability and appearance of the machine tool.
  5. C-shaped plates are installed on both sides of the fuselage, and high-precision grating rulers are installed on the C-shaped plates. This avoids the impact of body deformation on bending accuracy during the bending process.

Machine High-End Configuration of Electro-Hydraulic Servo CNC Plate Press Brake Bending Machine

German Alpha DE-15 CNC System

  1. Supports angle programming and depth programming switching
  2. Supports mould library and product library settings
  3. The shifting point position can be controlled freely
  4. Supports large arc automatic generation program
  5. Supports automatic bending to achieve unmanned bending control, and can support up to 25 working steps of automatic bending

Die Clamping Device

  1. The bending mould is made of 42CrMov material and is quenched as a whole
  2. The standard double-V lower mould has grooves of different sizes and shapes for selection, making mould replacement convenient and suitable for bending regular plates
  3. Uses high-strength cast iron and a unique internal muffler design, resulting in lower noise

Electrical Parts

  1. The machine is equipped with Eston’s original self-adaptive electrical box assembly, which offers strong anti-interference ability and stable electrical performance
  2. Compared with the traditional stepping motor, the servo motor improves precision to ± 0.01 mm, reduces noise to 25 decibels, lowers energy consumption by 60%, reduces hydraulic oil by 70% in the oil pan, and improves efficiency by 30%

Automatic Compensation System

Calculates the compensation value based on the overall deformation of the ram and table, making the deformation curve of the bed seamlessly aligned with the compensation curve. This ensures the best straightness and angular consistency of the product.
