CNC Bender for Sheet Box with DA66T 2 Axis Backgauge

The electro-hydraulic servo CNC Bender mainly adopts the sheet metal bending machine structure.

It is composed of a fully closed-loop CNC system of the bending machine, two grating scales, a photoelectric encoder for real-time detection feedback, and a stepper motor driving screw to form a fully closed-loop control.

125T/4000 DA66T  CNC Bender with the crowning system for improved quality, a servo-driven back gauge system for increased speed.

Also has increased working speed, stroke, daylight, and pressing capacities of the machine.

The future – as a result of rising energy costs and increasingly cost-efficient speed-controlled drives offered on the market, variable-speed solutions are in advance.

This series is fully by European standards, high precision, high security.

Features of 125T/4000 DA66T CNC Bender sheet forming

1. Bending angle calculation and back gauge position calculation can be achieved by inputting metal sheet material information, sheet size, and punch and die size.

2. Crowning system can work with a CNC controller automatically to achieve higher bending accuracy and linearity. Hydraulic crowning and motorized crowing systems are optional.

3. CNC crowning ensures a constant bend angle across the full length of the machine. This is achieved by pre-loading the machine, to offset any possible deflection under load or compensate for any tool wear, so that under load contacting surfaces are parallel to each other.

Performance characteristics of hydraulic servo CNC Bender

1. The DA66T Metal press brake sheet forming adopts a hydraulic convex automatic compensation system to solve the influence of the deformation of the slider during the bending process on the quality of the workpiece. The amount of compensation is automatically adjusted by the CNC system, which is convenient and accurate.

2. The CNC bending machine sheet forming adopts a full-function back gauge mechanism, which can choose to control multiple back gauge shafts. Functional parts in the back gauge. Imported originals such as guide rails, screws, and bearings are used to ensure the accuracy of the back gauge.

3. The body of the Hydraulic Bender Machine adopts an integral welding structure, which is convenient for transportation and processing and can ensure the accuracy of the machine.

4. The machine body, slider, and other important components are analyzed using ANSYS finite element analysis software to ensure the reliability of the machine tool.

5. The hydraulic bending machine adopts the integrated control system imported from Germany, which reduces the installation of pipelines, improves the working stability of the machine tool, and has a beautiful and concise appearance.

Among them, the DA66T controller is popular among the customer. Its advantage as below

1. The electro-hydraulic servo system controls the double-cylinder synchronization and cooperates with the international standard grating ruler to form a fully closed-loop control. The synchronization control has high precision, and the bending accuracy and repeated bending accuracy also reach a high level.

2. According to user needs, it can have a hydraulic upper mold automatic clamp or a quick clamp, a slot type lower mold, which can reduce the labor intensity of workers and improve production efficiency.

3. The fully functional back gauge mechanism can have six axes. The compensation adjust automatically  by the CNC system, which is convenient for compensation

4. There are segmented upper dies of different lengths, which can assemble into a certain width according to the requirements of the workpiece to meet the processing needs of special workpieces.

5. The CNC oil cylinder deflection automatic compensation system overcomes the influence of the deformation of the slider on the quality of the workpiece during the work process and ensures good straightness and bending angle of the processed workpiece.

6. The flexible operation mode can be used, which can link the two machines to solve the processing of ultra-long plates, process the short pieces in a single machine, improve the utilization rate of the machine tool, and reduce energy consumption.

7. Intelligent module structure, built-in PLC function, automatic programming and bending simulation, collision detection function, can realize remote diagnosis, high-resolution true color TFT display.
