Graphite emulsifier liquid cooling but lubricates, but disadvantage is that, need that manual operation, automation is low, working efficiency is low, in addition,
Graphite dust is not only harmful to human body and harmful to electronic component.
For another example Chinese Patent Application No.：2014207417919, the applying date：On December 02nd, 2014, invention and created name
For：Forcing press forging mold automatic lubrication installation, this application discloses a kind of forcing press forging mold automatic lubrication installation, packets
It includes cylinder, be installed on the spray thrower of cylinder piston rod head end and the water pot for storing graphite aqueous solution.Press forging completes
After part, sliding block backhaul is triggered close to switch I, is closed close to switch I when sliding block rises to upper dead center position, when control
Between relay work, Unidirectional solenoid valve II or Unidirectional solenoid valve III be powered on, and the piston rod of cylinder is made to drive spray thrower forward
Movement.When moving to certain distance, the piston triggering of cylinder is close to switch II, and control Unidirectional solenoid valve I is opened, since water pot is logical
It crosses air inlet and is connected with air source, therefore compressed air makes the graphite water in water pot be easy to be flowed into spray thrower, realize that spray arrives
Lubrication mold on upper die and lower die.The time relay was disconnected in several seconds time back contacts；Cylinder pulls spray thrower backhaul
Movement, the at this time power-off of Unidirectional solenoid valve I, spray stop.This application reduces manpower, improves production efficiency；But the Shen
Please case be disadvantageous in that power plant is cylinder, complex process, and waste of energy.
In conclusion providing a kind of cooling system simple in structure, easy to operation, can efficiently realizing uniformity cooling and lubricating
System is still tireless pursuit in forging industry.
