2. Accuracy of the machine
Y1-Y2 axis: Linear encoder for electronic ram
depth—setting, equilibration, calibration
Y1, Y2-axis are the independent motion parameters of two cylinders
controlled by CNC control system. Both ends of machine with a high-precision
(resolution 0.005mm)
linear guide from Germany, which used to determine the exact distance of the
ram and the table, linear guide is connected with the table, eliminating the
deformation of the slider position column impact. Ram running speed and
location data through the two optical grating timely feedback to the CNC system,
CNC system to calculate and output the servo valve control signal S1 ~ S2,
control of two electro-hydraulic servo valve output flow, so that the two
cylinder simultaneous .
Repetition
accuracy +/- 0.01 mm
Accuracy of positioning +/- 0.02 mm
V axis: automatic bed crowning by CNC Controller.
Deflection of the bed and ram under bending load is an unavoidable
fact of life with any brake, which tends to cause bed angles to be inconsistent
from center to ends of part. The problem is further compounded by the fact that
bending loads are constantly changing for job to job and even within the same
part, due to variations in material strength, thickness, and bend angle, bend
length and other factors. YSD’s adjustable bed crowning system will automatically
calculate and adjust the amount of crown on the bed to the proper position from
bend to bend if so needed.
The crowning table composes of many crowning wedges, they could move
relatively, and one group of ideal curve could be achieved on the crowning table.
Thus linearity of bending product could be guaranteed.
CNC crowning ensures the ram and table are parallel during the
bending operation. Sheet thickness, length, die opening and tensile strength
data are entered into the control. Force and related deflection of the table
and ram are automatically determined, preloading is optimally obtained for each
bend. With YSD HPS press brakes, you obtain an optimal bending process and
excellent bending results form the first piece.

3. Machine structure
3.1 For
the best rigidity and performance of the main machine body, the frame and
Component is designed and Finite Element Analyzed under ANSYS/UG software.
3.2 Full
steel connected structure, stress released through vibration by adopting
Germany technology, with rigidity and accuracy well kept. Warranty for the main
frame of the machine is full working life.
3.3 The
welding frame for big YSD machine have crack detection through ultrasonic.
The structure parts on machine with rust removed through sand
beating. Also spray With rust-proof paint.
3.4 For
the one-time machining of uprights, up ram and working table, SKODA and 5-Axis
TOSHIBA CNC boring & milling machine is adopted. Thus the parallelism and
Uprightness between all mounting surfaces could be guaranteed.
4. Hydraulic system
4.1 Modularized
hydraulic system is adopted, and the pipeline and connections are reduced to
the minimum level to ensure minimum maintenance.
4.2 Hydraulic
Valve block including proportional servo valve and pressure valve is adopted
from Germany.
4.3 High-pressure
internal gear pump from Voith, Germany or NACHI, Japan with reliability and low
noise.
4.4 Quality
oil seals from MERKEL, Germany are adopted. With secure sealing and long life.
4.5 YSD
quality cylinders ensure high reliability and safety.
Hydraulic cylinder and Piston is with hot forging, and with one-time
machining on CNC lathe. CNC cylindrical grinding for roundness and super fine
machining on horning machine for smoothness is adopted on the cylinder. CNC
cylindrical grinding for roundness and vibration super-fine machining on the
outer surface for smoothness is adopted on the piston rod. Hard chroming is
adopted on the surface of the piston.
4.6 Relief
valve is adopted to protect the oil pump and hydraulic system when
over-loading.
4.8
With oil leveler to indicate
the level of oil tank.
4.8 With
precise guiding system, position measuring system and the function of hydraulic
equilibrium, bending over whole length with good accuracy could be achieved.
4.9 The machine can run
continuously under rated load, without oil leakage in hydraulic system. With
reliability and accuracy.
5. Electrical system
5.1 Electrical
design according to international standard and meet customer’s requirement.
With
reliability, anti-jamming and long life.
5.2 Main
electrical components adopt product from TELEMECHANIQUE France.
5.3 Cooling
fan is adopted. With heat releasing function for electrical cabinet.
5.4 Remote
foot pedal, with emergency stop function.
