Servo-Hybrid Presses

Locatelli Meccanica is developing a new line of Servo-Hybrid presses.
With these machines, we will be able to offer all the benefits of the servo technology, which are flexibility and reliability: the accuracy of the slide movement enables the manufacturing of high precision components, and the possibility to program the slide speed with fast, slow and standstill phases expands the forming options.
The benefits for the productivity are evident:

  • Reduced cycle times.

  • Optimized forming speed leads to better tool life and reduced tool wear.

  • Unimagined possibilities in the design of metal forming processes.

  • Reduces maintenance costs by reducing the hydraulic components.

  • No oil heating.

All these presses will be available with ESA Controls Siemens compatible (Made in Italy) and with Voith Technology (Made in Germany).

In Addition:

  • High performances through scalable and variable drive axe.

  • Protection and monitoring functions with the emphasis on tool. protection and press force monitoring.

  • Flexible production through automatic calculation of an energy-optimized movement for the press piston.

  • Increased energy efficiency through innovative energy management.

    Controlling options include:

  • Frequency controlled drive.

  • Integrated press force monitoring.

  • Pressure curve monitoring.

  • Electronic cam control, counting cams, timers, etc.

  • Integrated tool safety system.

  • Various parts counters.

  • Product Management.

  • Switchable sockets.

  • Integration of peripheral equipment.

  • Remote access via modem.

  • Interface for the production data acquisition.

  • Special applications.

These presses have a precise mechanical slide drive, which provides a constant passage as with a conventional mechanical press, and thus a consistent parts quality. The slide speed within a stroke can be programmed and altered as with a hydraulic press.

A servo drive with an integrated drag-link mechanism are eco-friendly as electric/hydraulic, down-acting system delivers superior accuracy. This high-performance features of a servo-hybrid drive system requires less hydraulic fluid than conventional machines, and the super-accurate ram is capable of repeatability within tolerances of ± 0.004 mm.

This combined drive enables an optimal adaptation of the slide movement to the requirements of the respective forming processes. The servo motor can be selected in a smaller version than for the direct servo drive. This, in conjunction with the choice of highly efficient servo motors and good feedback modules, provides a significant potential for energy savings while at the same time delivering an increased flexibility and complexity.

In conclusion, the servo-hybrid press combines the advantages of a mechanical and a hydraulic press, and practically defines a new press generation which enables applications which were previously thought to be impossible.
