SERVO PRESS with Servo Die Cushion
[PATPEND]
|
|
■Optimum motion for forming and transfer has realized a world-class productivity.
■Servo Die Cushion boasting the world's best accuracy of load control has improved forming quality.

|
|
| ◎ |
Optimum slide motion for panel transfer has been realized with a high-torque and simple crankless mechanism.
Combining with "Hexa-Feeder" with Servo press, production speed, 20 spm in maximum can be achieved.
(in case of Tandem press Line) |
|
| ◎ |
A newly-developed software "Motion Maker" can support to produce an optimum motion. |
|
 |
|
◎ |
Low noise |
Pre-acceleration function of servo die cushion reduces
noise by about 25 dB(A)comparing with pneumatic cushion. *Cushion starts descending just before slide touches blank holder. |
◎ |
Energy-saving |
There is no heat generating loss by intermittent running as a
clutch brake is not equipped.
Die cushion recovers driving energy and can save power
consumption as much as 40%. |
◎ |
Oil -saving |
Large quantity of hydraulic oil is not used in servo die cushion
since H&F's servo die cushion is mechanically direct driven type.
Only space for lubrication unit is required in a pit. |
|
|
◎ |
It is no need to take any measure for harmonic disturbance by adopting sine wave PWM Converter. |
◎ |
We are ready to cope with customer's power capacity measure by using capacitor bank. |

Upgrade Panel forming quality by epoch-making Servo Die Cushion
|
◎ |
Forming Mode |
Adjustable to any kind of forming conditions with Die cushion. |
◎ |
Load Control |
Capable of load change in forming and acceleration/deceleration of slide. |
◎ |
Hybrid Mechanism |
Both a high accuracy and a high capacity are realized by using air cylinder. |
◎ |
Rack & Pinion Mechanism |
A high efficiency and a longer life time are realized without heat generation. |
◎ |
Pre-acceleration function |
Capable of corresponding to max. slide speed 700mm/s.
Touch speed of upper die versus blank holder is capable of setting arbitrarily. |
| Effect : ■Improvement of material yield ratio |
■Capable of using lower grade materials |
■Stable strains of stretch forming |
■Reduction of trial-hour |
■Digitalized data control of forming conditions |
