II. Machine performance and features

2.1 Machine performance

• All new rigidity design and finite element analysis, reduce maximally the influence to the bending quality due to deformation.

• Adopt Full Closed loop Electro-hydraulic servo synchronized control system imported by Germany

◆ Simple style of the new process design, the appearance of beautiful and generous, painting using Aksu paint imported from the Netherlands.

3.2 Machine frame

◆ Whole-body full steel welding, good shock resistance.

• Large tempering furnaces are used to release stress, non-deformation to the machine frames.

• One-time machining by pentahedron machining centers from Spain, quality assurance to parallelism and perpendicularity on all installation surface.

• C-shape plate mechanism is installed near the throat in the machine frame to detect the distance between upper and lower tools, to guarantee the precision of the bends.

3.3 Ram structure

◆ Upper beam movement (ram), low noise, stable works.

◆ Thicker and wider ram, reduce maximally the crowning deformation during the bending.

• Universal installation surface for the punch, can meet different clamping requirements to the maximum extent.

3.4 Hydraulic system

• The most advanced full closed-loop electro-hydraulic servo synchronization control system, integrated with high frequency response valve control technology, brings higher speed, higher precision, and better efficiency and performance.
• Full set of hydraulic system from Hoerbiger, Germany, with proportion valve differential pressure balancing function to reduce oil temperature and improve the stability of the hydraulic system.
• Y1 and Y2 can be programmed individually, can work under eccentric load condition, and can make conic bending.
• With holdup time at BDC, can be programmed to ensure the precision of different bending.
• With low speed return control function, the operator can make a better control of the bended part.
• Magnetic linear scale from GIVI, Italy. High precision guiding system, positioning system and
• Hydraulic pressure balancing function can meet all requirements for full-length or eccentric bending.
• Sealing components from SKF, Austria, strong sealing performance and long life time.
• Piping parts and joints are international brands, good quality and outstanding performance.
• The hydraulic system has overload overflow protection.
• Obvious display of oil level.
• Machine can work non-stop under rated load, and the hydraulic system can remain in leak-proof condition and ensure high precision and stability to the continuous works.

3.5 Back gauge system

• Fit to make multi-bends and high precision bends.
• High speed and high positioning precision.
• Ball screw transmission for X , guided by linear guides, driven by digital AC servo motor, with return control function.
• 3 units finger-stops moving along the dual-linear guides, easy to use, very high precision.
• Box-type back gauge beam structure, with more than enough mechanical strength and rigidity
• Individual finger-stop structure to increase back gauging range.

3.6 Electrical system

• All electrical components are from overseas companies or joint ventures, following international standard, safe and reliable, long life time, and strong anti-interference ability. Power cabinet is equipped with heat dissipation device.

3.7 Crowning system

• Worktable is equipped with mechanical crowning system, closed-loop control, compensation value is automatically calculated by the controller, making sure the bending angle in full-length remains the same.
