AC Servo Presses H1F-2series – Komatsu Industries Corp.

Just one press of ours, having long stroke length of No. 1 among competition and combining with pendulum motion, makes both general-purpose use and high productivity compatible.

With the longer stroke length, production speed is the same or faster than conventional machines! It provide you with wide general-purpose applications.

It has the long stroke length, of No. 1 among competition, to cope with variety of products.
Setting at the lowest stroke length to meet the product height with the pendulum motion, high productivity can be achieved.
With this servo press of excellent versatility, you can flexibly respond to the market variation.

Stroke length is No. 1 among competition

The stroke length is longer even than that of our previous servo presses by 20 – 33 percent.

For improving forming performance

It is commonly accepted that low speed forming is suitable to general drawing and bending, and that low speed forming and stop motion at bottom dead center to plate forging and crashing. On the other hand, lower slide speed and stop motion are contradictory to high forming performance and make productivity lower.

For improving productivity

Moving the slide at the highest speed while not forming, and using the most suitable motion while forming (die touching through finishing) will make increase production speed.

Trial and error motion change

But generally it is impossible to know momentary starting (die touching) point of forming visually. Trial and error motion setting was necessary for pursuing productivity.

Troublesome motion setting is resolved by our “”Optimizing Motion System (OMS).””

Just try forming once and press a button. The die touching point will be recorded. About in one minute.

Maintaining product accuracy for a long time

Doesn’t product accuracy variate after some time?

With the reverse motion, further “”ultra””-high precision forming is made possible.

With the full closed feedback control, “”ultra””-high precision forming can be realized.

Use the reverse motion for products that require further bottom dead center accuracy, as in half blanking.
The full closed feedback control that makes the slide reverse before the bottom dead center based on the actual slide position measured by the linear scale maintains every bottom dead center position to realize “”ultra””-high precision forming.

The same power source capacity with conventional mechanical press

Is your power source capacity enough?

Power source capacity and consumption of mechanical press

With the mechanical press, forming is done accumulating forming energy by rotating the flywheel. Required power source capacity is relatively small, but it always consumes power since it constantly rotate the flywheel.

Power source capacity and consumption of conventional servo press

The servo press forms and accelerates receiving energy directly from the plant power source. It requires large amount of energy (electric current) momentarily on forming and therefore relatively large power source capacity, but overall power consumption is relatively small since it consumes power only on forming.

You may have to increase power source capacity

Previously, when a mechanical press is replaced with a servo press, energy could be saved, but oftene power source capacity had tobe increased.

The peak power currency suppression capacitor (optional) suppresses power source capacity.

When a mechanical press is replaced with a servo press, power source capacity hasn’t to be increased if a peak power currency suppression capacitor (optional) is equipped.

Peak power currency suppression capacitor (optional)

By storing power in the capacitor from the primary power source and by using it on forming and accelerating, the same power source capacity as for the previous mechanical press can be used.
On the other hand, by storing power that the press generates on deceleration and using it on forming, power consumption can be saved. Using the same power source capacity as for the mechanical press, energy saving can be achieved.
