1.Hybrid Press Brake Overview

1.1 The machine features a split steel plate welded structure for its body. After the welding process, the machine undergoes treatment in a large tempering furnace to eliminate any stress-related deformations, ensuring long-term precision.
1.2 The two main side cylinders are synchronized with well-known electro-hydraulic servo valves and Spain's Fagor optical grating scales. This closed-loop control system provides high feedback accuracy.
1.3 The V-axis mechanical compensation compensates for any deformation in the ram during the bending process, which could affect the quality of the workpiece. The compensation is automatically adjusted by the CNC system for precise control.
1.4 The backgauge structure is fully functional, with the option to control multiple axes. Components such as guide rails and bearings are all imported, ensuring precise backgauge positioning.
1.5 The machine body uses a split assembly structure and undergoes a comprehensive machining process, ensuring overall precision.
1.6 Critical components like the machine body and ram are analyzed using ANSYS finite element software, ensuring the machine’s reliability.
1.7 The hydraulic system incorporates an imported integrated control system, reducing piping complexity, improving stability, and offering a clean, sleek appearance. The upper die is modular, allowing for different length configurations to suit various workpieces. The upper die features a safety groove structure (European standard), while the lower die uses a combination design for versatile bending applications.
1.8 The CNC system is available with Delem, Cybelec, or ESA controllers.
1.9 The machine is equipped with C-shaped plates on both sides, with high-precision optical grating scales installed on them. This setup prevents the machine body from deforming, ensuring consistent bending accuracy.
1.10 Hydraulic cylinders are manufactured by specialized factories, using German-imported seals and pipe connectors to prevent oil leakage.

2.High-Precision Hydraulic Servo Synchronization Control System

2.1 High-Precision Optical Grating Scale

The machine uses a high-precision optical grating scale as a displacement sensor, mounted on the C-type throat. It provides feedback accuracy of up to 0.001mm, helping maintain precise control over the bending angle.

2.2 ESVP Energy-Saving System

2.2.1 Compact design with a simple installation structure, offering improved energy efficiency and reduced oil consumption.
2.2.2 Powered by a servo motor, the system runs more quietly and efficiently.
2.2.3 The system comes standard with Rexroth valves and Rexroth pumps, known for their stability, reliability, and longevity.
2.2.4 The cleanliness of the hydraulic oil is improved from NS7 to NS9, significantly lowering failure rates.
2.2.5 The system eliminates the need for proportional valves, throttle valves, and pressure relief valves, reducing hydraulic oil consumption by up to 60% compared to traditional hydraulic bending machines.

6.CNC Back Gauge-- 4+1+2-Axis CNC Back Gauge:

X-Axis

• Utilizes linear guides, ball screws, and servo motor-driven mechanisms to ensure precise positioning of the X-axis.

 R-Axis

• Powered by a high-power servo motor, combined with linear guides and ball screws, delivering rapid response and precise positioning.

Z1/Z2 Axes

• Controlled by CNC servo systems for synchronized and accurate operation.

 X-axis Servo Motor
The X-axis is driven by an industrial-grade brushless servo motor, paired with a quiet synchronous belt, ensuring precise synchronization.

CNC X-axis and R-axis

The X-axis uses linear guide rails and a ball screw, driven by a servo motor to ensure precise positioning.
The R-axis uses straight-tooth gear rails, with a high-power servo motor and a reducer coupled to a high-torque shaft, offering quick response and precise coordinated positioning.

CNC Backgauge Z1, Z2

The backgauge is mounted on dual guide rails and is directly driven by a servo motor, equipped with a fine-tuning device. The three-stage structure ensures excellent parallelism, stability, and reliability.
