Machine Structure

1, Outline Feature

• New rigid design with finite element optimization analysis to minimize the impact of bending deformation on workpiece quality.

• High frequency response proportional valve ensures stable operation at high speed 200 mm/s, enhancing synchronization accuracy and processing efficiency.

• Differential pressure balance system controls hydraulic temperature rise, reducing it by about 10°C compared to conventional systems, ensuring long-term stability.
• High dynamic response hydraulic compensation system maintains precision in both standard and sheet bending operations.
• One-way servo pump technology saves over 40% energy, extends hydraulic component life, and reduces maintenance costs.

2, Frame

• Complete steel plate welded structure with excellent vibration resistance.
• Tempered to eliminate internal stress, ensuring good stability.

• Machine body is machined using a five-axis machining center from Spain, ensuring parallelism and perpendicularity between all surfaces.

• Equipped with a "C" shape at the throat for deformation compensation, directly measuring the distance between upper tool and lower die to ensure workpiece precision.

3, Ram Structure

• Upper stroke design for bending, low noise, and stable operation.
• Thickened and widened slider minimizes bending deformation.
• Unique dual-track structure ensures smooth sliding motion.

• Universal mold mounting surface meets maximum mold clamping requirements.
• The lower part of the slider has a scale with metric and imperial display, aiding operators in changing tools and finding the bending center.

4, Hydraulic System

• Advanced closed-loop electro-hydraulic servo synchronization control system with high-frequency ring valve technology for high-speed, high-precision performance.
• Hydraulic control system uses imported Germany HOERBIGER components with proportional valve pressure balance function to reduce oil temperature and improve system stability.
• Y1 and Y2 can be programmed separately, enabling partial load operation and conical bending.
• Bottom dead center has programmable pressure time to ensure accuracy for different parts.
• Slow return control function allows better operator control of the workpiece.
• Imported GIVI linear optical reader, guiding system, positioning system, and hydraulic balancing system ensure full-length or eccentric processing accuracy.

• Cylinder treatment includes rough treatment, hardening, inner grinding, and inner float boring, ensuring high precision and wear resistance.
• Hydraulic pipe fittings and seals are SKF brand, imported from Austria, offering high quality and performance.
• Hydraulic connectors are imported from Europe and America, ensuring reliable quality.
• Overload overflow protection prevents leaks and ensures safe operation.
• Oil level is easily visible for quick monitoring.
• Continuous operation under rated load with no leakage, stable performance, and precise positioning.

5, Back Gauge

• Excellent for multi-step bending with high precision requirements.
• Fast speed and high precision, with ball screw movement guided by linear guides and driven by digital AC servo motors.

• (Optional) Z1, Z2 axes move left and right along linear guides automatically, providing ease of use and high precision.
• Back gauge beam is tank structure, offering sufficient mechanical strength and rigidity.
• Special finger-stop design expands the range of the back gauge.

6, Electrical System

• Electrical components are imported or from joint ventures, meeting international standards, ensuring reliability, longevity, and strong anti-interference capability.
• Includes a movable panel for convenient operation and emergency stop functionality.

7, WILA Mechanical Crowning Compensation

The WILA mechanical crowning system integrated into the table allows automatic adjustment via the CNC controller. Point-focal adjustment options provide precise basic settings for accurate bending angles.

8. CNC Control System Standard is DELEM DA58 (2D Graphic Display and 2D Programming)

Optional: DELEM 66T

9. Others:

• Standard step-adjusted front support with rotating function to avoid workpiece damage during bending (see below).

• Foot switch and bottom plate equipped with wheels for easier mobility.

10. Lasersafe Safety Guard: LaszerSafe Safe Protection LG-005
