ELECTRICAL AND ELECTRONICS PROJECT CRITERION:

The thermo-moulding HYDRAULIC PRESS IS projected with:
- SIEMENS SIMATIC C7-626 2DP programmable displayed controller with PROFIBUS iterated interface
- WAGO decentralized peripheral
- SIEMENS series SIRIUS electro mechanics
- TELEMECANIQUE control panel
-  WEIDMULLER plug and terminal 

The electric and electronic projects are conditioned by:

THE SAFETY:

The press is protected on the front and on the back by three channels optical barrier, 2 hardware +1 software; they are auto checked every work cycle. The emergency and command inclusion circuits are separate, each circuit is controlled by a certified safety device and every device has got 2 hardware + 1 software channels. The sleight slope and stamp hydraulic movement actuator, in addiction to be controlled by emergency circuit, command inclusion and the safety barrier, are controlled by a certified bimanual command, this device has got 2 hardware + 1 software channels. A special program, control one by one the emergency circuits to prevent they exclusion. A safety dead bolt, is auto plugged in to lock the sleight at each press cycle; the impose program stop up quote, is adapted automatically between the 6 possible lock quote. If the identification plug is present on the stamp, the press can identify it to avoid program error. The press can identify the operator if his code is in the operator list, to avoid manipulation by unauthorized personal, for the same reason 9 password levels takes care the program data access. Every components are certified and installed respecting the CEE directive.

FLEXIBILITY OF USE:

The automatic working program was created to be totally flexible, to allow the technologist to adapt programs in accordance to his necessity and competence. In order to do this, for example, we have introduced the work rush speed and pressure profile, the free definition of the pressing and degas number, every of each phases, with pressure, speed and time pressing can be septate separately. Regarding the flexibility of the use, a chapter have to be spent for the press/stamp synergy, expressed by sixteen oleo-dynamics border stamp unit, eight for the upper part and eight for the lower part, directly controlled by the press software. Each unit can be connected in the desired stamp section, by the software. Further each of the four active stamp section can be septate with a different cycle, as  preferred from: blanking, moulding or saddling, with time, pressure and work order different by program to program. The stamp, recognized by the press means the identification plug, can work with different programs. The programs resident in the file, can be easily modified, duplicated, renamed and deleted, also when the machine is working, without stop it because the active program is independent by the displayed program.

TOTALY PARAMETRIZATION:  

All the component mounted on the press are characterized  with setting data, resident in the PLC memory. That means, if need to replace a bad component, (solenoid valve, position transducer, pressure transducer), a calibration on the new component isn't necessary. Is easy to modify the characteristic of a component, with the reserved access menu. This possibility has to be authorized by the MC2 technician.

CONNECTION TO OTHER PERIPHERAL

The Profibus net, where we have connected CPU, all the peripheral, actuator, solenoid valve, pressure transducer and position transducer, is easy to connect to others peripherals like supervision net, integration between systems ( manipulators, power supply, cut machine etc.). For example, two press can be connected together and exchange they data, connected to a centralized supervision system, or connected to a data collecting net. A press can be connected via modem, to the MC2 technical service by the TELESERVICE.
