S---Â WILAÂ mechanical compensation crowning system
Â
Â
Machine structure
1,Outline feature
New rigid design, finite element optimization analysis, to minimize the impact of bending deformation on the quality of the workpiece.
Â
The use of high frequency response proportional valve, high dynamic response performance to ensure that the machine at high speed 200mm / s stable operation, while greatly enhance the Y1 and Y2 running synchronization accuracy, and to achieve high bending processing efficiency.
Â
The use of differential pressure balance system, the hydraulic system overflow in advance control, effective control of the hydraulic system temperature rise, the hydraulic system temperature rise than the conventional pressureless balance system of the bending machine reduced by about 10 ºC, the oil temperature decreased hydraulic failure, Long-term use of machine tools to stabilize.
High dynamic response hydraulic compensation system, not only to ensure the accuracy of conventional bending the accuracy of the workpiece, and the accuracy of sheet bending can also be effectively controlled.
One-way servo pump control technology, not only can achieve more than 40% energy saving, hydraulic oil system can also be reduced to extend the life of hydraulic components, sealing components, reducing the frequency of replacement of hydraulic oil, reducing the cost of customers And maintenance costs.

slider thickening, widening, bending deformation will be reduced to a minimum;
unique dual-track structure (as shown below), slider running more smoothly;
Â
universal mold mounting surface, can meet the maximum clamping requirements of the mold;
The lower part of the slider is equipped with scale, metric and imperial double scale display, easy for the operator to change the tools and find the center for bending.
Â
Â
4,Hydraulic system
Using the most advanced closed-loop electro-hydraulic servo synchronization control system, and integrated high-frequency ring valve control technology, can achieve high-speed, high precision, high efficiency performance;
Hydraulic control system sets imported Germany HOERBIGER company, with proportional valve pressure balance function, reduce oil temperature, improve the stability of the hydraulic system; Â
Y1, Y2 can be programmed separately, can work in the partial load state, but also cone-shaped bending;
bottom dead center has a pressure time, programmable, to ensure that the accuracy of different parts;
 has a slow return control function, the operator can better control the workpiece;              Â
Imported GIVIÂ linear optical reader,guiding system,positioning system and hydraulic balancing system with high precision, which all can permit the processing work piece of full length or with eccentric.
Â
Special treatment about the cylinder--rough treatment--hardening--inner grinding--inner Float boring, make the inner side of the cylinder with high precision and wear resistant
Pipe fitting and seals of hydraulic system is SKF brand which imported from Austria, good quality and high performance
Hydraulic connector are imported from Europe and America;,with good quality
Overload overflow protection is outfitted to hydraulic system, which can assure no leakage.
Oil level can be read or seen directly
Being able to work continuously under rated load and hydraulic system shall have no any leakage, stable working, high precision positioning
Â
5,Back gauge
Good for work piece needing multiple steps of bending with high precision requirement
The speed of back gauge is fastest,and high precision.
X,RÂ axis of back gauge is moved with ball screw, guided by linear guide, and driven by digital AC servo-motor.
Â
(Optional) Z1, Z2 axis two blocks  move left and right along the linear guide automatically, easy to operate, high precision;Â
Back gauge beam is tank structure,with good enough mechanical strength and rigidity             Â
Particular finger-stop design, enlarge the range of back gauge.
Â
6,Electrical system
Electrical components are imported or from Sino-foreign joint Venture, in accordance with international standards, reliable safety, long life, good anti-interference ability
Equip with movable food panel,convenient operating,emergency stop
