Description
Technical field
The utility model relates to machine tool lubrication technology, particularly a kind of forcing press Lubrication Control System.
Background technology
In forcing press industry, between each parts, lubrication is the necessary requirement ensureing that press normally runs safely and effectively.Incomplete lubrication can increase the wearing and tearing of press part, reduces press parts and press life-span, increases maintenance cost, reduces production efficiency.
Existing forcing press Lubrication Control System is primarily of PLC, HMI man-machine interface, Lubricating pump station, proximity switch composition.Its operation principle is the proximity switch induction lubricating impulse signal by being arranged on separator pulse bar place.If oil circuit is unimpeded, pulse bar does piston movement, and what now proximity switch sensed is pulse signal alternately, and during oil circuit blocking, separator pulse bar can stop motion.Because position when pulse bar stops is not fixed, so now proximity switch has signal or never has signal always.When proximity switch has signal for a long time or do not have signal for a long time, PLC Programmable Logic Controller exports lubrication trouble through operational analysis, to reach the object stopping Lubricating pump station and stop forcing press.But there is following shortcoming in this scheme:
1, proximity switch uses nut to be fixed on the other support of pulse bar, press must produce comparatively big bang in the normal ram workpiece trends of the times, the position of proximity switch and support can offset to some extent along with the increase of punching press time, and proximity switch requires higher to distance of reaction, the movement of proximity switch position can make it respond to less than signal, so there will be the induction of actual oil circuit unobstructed and proximity switch less than signal, cause PLC to export situation that lubrication trouble causes shutdown; 2, proximity switch is installed on by separator pulse bar, separator position has more lubricating oil, and particularly press connecting rod place lubricating oil is more, environment is poor, long-term oil stain infiltration can corrode switch main body and control circuit, cause proximity switch reliability and sensitivity decrease, cause misreading of signal, shorten the service life of proximity switch;
3, the proximity switch at press connecting rod place is installed on connecting rod place, and during machine tool running, proximity switch and control cable can move with the motion of connecting rod, and As time goes on, cable can wear and tear and even break.In addition, connecting rod is positioned at gear-box, and as proximity switch damages, changing the proximity switch at connecting rod place needs to creep in gear-box, and gear-box space is narrow and have a large amount of lubricating oil to cause to change very inconvenient.The mounting means of proximity switch and installation environment cause proximity switch very easily to damage, and therefore the proximity switch of lubricant housings has become the consumable accessory that forcing press industry is generally acknowledged.Change the cost that proximity switch adds machine maintenance greatly frequently, and reduce production efficiency;
4, existing Lubrication Control System can not show real-time oil circuit pressure value, and automaticity is not high enough, can not meet the demand of high-end user.
Utility model content
The problems referred to above that the utility model exists for forcing press lubricating system of the prior art, provide a kind of safe and reliable, automaticity is high, the forcing press Lubrication Control System of long service life.
The purpose of this utility model realizes like this, a kind of forcing press Lubrication Control System, comprise Lubricating pump station, pressure sensor, PLC, analog quantity modular converter and HMI man-machine interface, described Lubricating pump station is used for the lubricating oil to forcing press each lubricating oil pipe supply certain pressure, described pressure sensor is arranged in each oil pipe needing to detect lubricating oil pressure, described pressure sensor is connected with analog quantity modular converter, described simulation volume modular converter is connected with PLC, described PLC is also connected with Lubricating pump station and HIM man-machine interface, described HMI man-machine interface is for showing oil pressure value and the fault alarm information of each oil pipe.
Installation for ease of pressure sensor connects, and described pressure sensor is installed in each oil pipe by oil circuit transfer block or pressure guiding pipe.
Detection for ease of pressure in oil pipe exports, and force value is converted to analog output by pressure sensor.
Forcing press Lubrication Control System of the present utility model, the force value of each lubricating pipe is detected by pressure sensor, and this force value is passed to analog quantity modular converter and PLC, according to the force value of pressure sensor, PLC judges that the oil pressure of lubricating pipe is whether in the normal oil pressure range of setting, thus judge whether each lubricating pipe breaks down, and each force value or fault message are passed through HMI man-machine interface display translation.Adopt the fault detection approach of the pressure signal of proximity switch inductive impulse beam hanger to have reliability in hinge structure and automaticity is high, long service life, concussion resistibility performance is good, and corrosion-resistant, high temperature resistant.
