Powerful Bending Function

Slow bending function

• • The slow bending function allows you to set the bending speed for easy operation. You can also set the position where slow bending starts and the waiting time between steps, with support for digital settings or manual selection, improving processing flexibility and precision control.

Pull-back and bending function

• • The pull-back and bending function is activated after the mold clamps the material. It first performs an up-and-down movement to confirm that the material is securely clamped, thereby preventing interference with the material during the bending process and ensuring smooth processing.

Circular arc bending function

• • The circular arc bending function enables automatic arc bending by entering spacing, converting steps into smooth curves with precision and consistency for sheet metal applications.

Line marking bending function

• • The line marking bending function ensures precise forming by positioning pre-drawn lines and optimizing parameters, molds, and intelligent systems, enhancing efficiency and consistency.

Hybrid Metal Press Brake (Standard Equipment)

Main Characteristics

Hybrid Metal press brake Design Concept:

ADV® EHP Series Hybrid Press Brake is an efficient, precise, energy-efficient and low-noise hydraulic hybrid bending solution.Our servo hybrid press brakes can save up to 80% of energy.

Advantages:

• • Low Noise Electro-hydraulic Hybrid Servo

• • No Leakage In Hydraulic Lines

• • Extended Oil Change Intervals

• • Low Thermal Equilibrium Temperature

• • High Volumetric Efficiency Of The Oil Pump

• • Mechanical compensation device: equipped with compensation wedges, and controlled by CNC numerical control system, the lower workbench produces pre-convex compensation for the flexural deformation of the upper slide, and the angle change of the workpiece is controlled within the tolerance range to ensure high-quality bending accuracy.

• • Throat deformation compensation device: The magnetic scale is connected to the workbench through a C-shaped frame, which eliminates the influence of the frame throat deformation on the position of the slide to the maximum extent. This structure can make the machine have anti-eccentric load capacity and effectively prevent non-standard workpieces from colliding with the magnetic scale.

• • Overload protection function: The hydraulic system can protect the machine tool from damage when overloaded.
    Mold parameter library: Establish a mold parameter library to facilitate customers to quickly obtain sheet bending parameters.

• • Intelligent angle compensation: The system automatically adjusts the bending angle according to parameters such as material properties, mold size, material thickness, etc. After one trial bending, the angle deviation can be corrected and put into production immediately.

• • Automatic bending pressure calculation: The system calculates the bending pressure and alarms when it exceeds the limit range.

• • Intelligent Tool Load Monitoring: Ensures tool safety during operation.

Applications:

• • EHP series Press Brake targets lightweight automotive parts, new energy batteries, 5G communication frames, and aerospace titanium. Processes high-strength steel, aluminum, and stainless steel, supporting curved surfaces and flexible production. Hybrid energy-saving tech aligns with low-carbon manufacturing.

• • The electro-hydraulic servo press brakes is a very reliable metal forming equipment, designed for complex and precise bending tasks. It combines hydraulic drive and servo control technology to provide it with powerful bending capabilities and excellent positioning accuracy.
