1. Fabricated ultrasonically tested steel construction of frame : |
Frame is fabricated from prime steel plates of
proper thickness for greater strength & rigidity. All frame is
designed on latest softwares to resist any deflection & capable
enough to withstand high pressure & vibration damping capabilities.
|
2. Accurate slide Guiding Arrangement : |
Different kind of guiding arrangement are provided
to suit the application of the press long guiding length & suitable
guide with centralized lubrication system is provided in the presses.
Please refer following pictures. |
3. Bottom Cushioning Arrangement : |
The function of the draw cushion is to hold the
blank during deep drawing operations. The cushion thus prevents the
formation of wrinkles & as a resuet of the ejection function, raises
the parts to the transport level or ejection level during the return
motion of the slide. The cushion is designed for about 30% of the main
ram tonnage when in cushion mode. |
4. Stroke Limiters & Damping device : |
Mechanical stoppers are provided as a safety
feature to limit the maximum stroke of the main ram after pressing, to
protect the tool from damage. |
5. Most Reliable Hydraulic Drive System : |
'PRESSWEL' hydraulic system is most reliable &
the backbone of hydraulic presses. It involves a compact manifold Block
to avoid piping thus less chance of any leakages in the system so
pressure will remain constant throughout the cycle. All the valves are
internationally reputed make, so reliability is more. High quality
indigenously made precision hydraulic cylinders with low friction PTFE
seals with 60%. Bronze guide tapes ensure operation & long life of
the press. |
6. Control System : |
The press controls are designed into a panel which
is mounted at type level on the press. A TFT Flat panel with touch
screen & key pad of world renowned "Allen-Bradley" is
provided so graphical display of control information, indication of
activation status of slide, cushioning & ejection operations are
possible. The blank holder, main slide & cushion stroke are
infinitely variable. Slide reversal is either by limit switch or
pressure switch sensing. The blank holder, main slide & cushion
pressures are individually controllable between 10-100% of tonnage
throughout the stroke. Individual pressure control of the various blank
holder cylinders or multi point cushion can be provided for drawing of
complicated & asymmetrical pasts. |
7. Operator's Safety Systems : |
|
8. Accuratel Slide Parallelism arrangement : |
A slide position sensor to detect deviation &
the servo valve to increase pressure on underside of the piston are
provided & at the same time the pressure on other connecting pipe is
reduced. The maximum deviation measured at the parallel control
cylinders is between 0.6 & 0.8 mm during drawing, bending, smc
moulding & other forming operations. |
