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 200 mm/s, improving synchronization accuracy of Y1 and Y2, thus enhancing bending efficiency.

 

• Differential pressure balance system controls hydraulic temperature rise, reducing oil temperature by about 10°C compared to conventional systems, ensuring long-term stability and reducing failure rates.
• High dynamic response hydraulic compensation system ensures high precision in both conventional and sheet bending operations.
• One-way servo pump control technology saves over 40% energy, extends component life, reduces oil change frequency, and lowers maintenance costs for customers.

 

2, Frame

• Complete steel plate welded structure with excellent anti-vibration properties.
• Tempering process eliminates internal stress, ensuring good stability.

 

• Machine body is machined using a five-axis machining center from Spain, ensuring parallelism and verticality across 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 (as shown below) ensures smooth slider movement.

 

• Universal mold mounting surface meets maximum mold clamping requirements.
• The bottom of the slider is equipped with a scale that displays both metric and imperial units, making it easy for operators to change tools and find the bending center.

 

 

4, Hydraulic System

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

 

• Cylinder treatment includes rough treatment, hardening, inner grinding, and inner float boring to ensure high precision and wear resistance.
• Hydraulic system pipe fittings and seals are SKF brand from Austria, known for high quality and performance.
• Hydraulic connectors are imported from Europe and America, offering reliable quality.
• Overload overflow protection ensures no leakage in the hydraulic system.
• Oil level can be directly observed.
• Continuous operation under rated load without any leakage, stable working, and high precision positioning.

 

5, Back Gauge

• Excellent for multi-step bending with high precision requirements.
• Fast speed and high precision in back gauge movement.
• X and R axes of the back gauge are driven by ball screws guided by linear guides and digital AC servo motors.

 

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

 

6, Electrical System

• Electrical components are imported or from Sino-foreign joint ventures, meeting international standards with reliable safety, long life, and strong anti-interference ability.
• Includes movable food panel for convenient operation and emergency stop.

 

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 ensure precise bending angles.
