Device people A continues forging to clamp placement force machine (6)；The corresponding impact force of experts database (1) warm area according to locating for initial forging temperature to
Main website PLC (3) sends corresponding field, and main website PLC (3) sends corresponding impact force to press machine (6) according to corresponding field
Instruction, press machine (6) are forged and pressed；Main website PLC (3) is by the on-off state of press machine, switching on and shutting down time, impact force and impact
Number data information reaches host computer (2), and the state of press machine is monitored by configuration software；
(d) press machine (6) forging and stamping issue feedback command to main website PLC (3) after completing, and main website PLC (3) gives robot B (10)
Action command is issued, robot B (10) is back to original position after forging is clamped placement bead cutter (7), and bead cutter (7) is to forging
Carry out trimming；Main website PLC (3) reaches the on-off state of bead cutter (7), switching on and shutting down time and trimming force data information upper
Machine (2), the state of bead cutter is monitored by configuration software；
(e) feedback command is issued after bead cutter (7) trimming is completed to main website PLC (3), main website PLC (3) gives robot C (11)
Action command is issued, robot C (11) is back to original position, cooling unit (19) after forging is clamped placement cooling unit (19)
Forging is cooled down；The status information of Logistic Unit (18) is reached host computer (2) by main website PLC (3), by configuration software come
Monitor the state of cooling unit；
(f) safe unit (20) includes safety door, safe grating and warning device, is arranged in the periphery of whole production line, when existing
When unusual condition occur in the safety door and safety optical grating device of field, safety door and safe grating send abnormal signal to safety PLC
(14), safety PLC (14) sends instructions to the warning device at scene, live alarm activation；Safety door, the safety light at scene
The status information of grid and warning device reaches main website PLC (3) by safety PLC (14), and main website PLC (3) again reaches information
Position machine (2), the state of safe unit is monitored by configuration software.
