Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of aluminium material extruder speed regulation and control system, including given potentiometer 1, voltage regulator
2, proportional pressure valve 3, stroking mechanism oil cylinder 4, oil pump 5, operating cylinder 6, pressure transmitter 7 and displacement sensor 8 are described given
Potentiometer 1, voltage regulator 2, proportional pressure valve 3 are sequentially connected electrically, proportional pressure valve 3, stroking mechanism oil cylinder 4, oil pump 5, work
Make oil cylinder 6 pass sequentially through oil circuit be connected, be connected with pressure transmitter 7, variable between the operating cylinder 6 and voltage regulator 2
Displacement sensor 8 is connected between organization cylinder 4 and voltage regulator 2.
Specifically, the utility model is controlled by hydraulic circuit, PLC can be selected to control.By given potentiometer 1 given one
A voltage signal is transmitted to proportional pressure valve 3 through voltage regulator 2, controls oil supply source 21 to stroking mechanism by proportional pressure valve 3
The oil inlet quantity of oil cylinder 4, the output oil mass of 4 control oil pump 5 of stroking mechanism oil cylinder push extruder operating cylinder 6 to work.By giving
The different voltage signal of certainty ratio pressure valve 3 controls the oil extraction pressure of proportional pressure valve 3, and oil supply source 21 is through throttling pad 1, section
It flows pad 2 12 and applies different pressure in 4 front and back chamber of stroking mechanism oil cylinder, its oil cylinder variable head is pushed to move.The movement of variable head
When, voltage regulator 2 is fed back to compared with given value through displacement sensor 8, and error signal constantly regulate proportional pressure valve 3
Oil extraction pressure controls the oil inlet quantity of stroking mechanism oil cylinder 4, realizes that variable head is static under any given position.Variable head changes
Change makes oil pump 5 export oil mass corresponding change, therefore can realize the adjusting of 6 speed of aluminium material extruder operating cylinder.
When squeezing work, the variation of 6 pressure of operating cylinder will cause the variation of 5 volumetric efficiency of oil pump, in addition system
Leakage loss can also change, and at this moment pressure transmitter 7 plays the role of pressure compensation when system works, and when the pressure was increased, pass through electricity
It presses adjuster 2 to adjust proportional pressure valve 3, to control the displacement that stroking mechanism oil cylinder 4 increases variable head, makes the oil extraction of oil pump 5
Amount is increase accordingly, to make up leakage loss incrementss caused by due to pressure improves.
Basic principles, main features, and advantages of the present invention has been shown and described above.This reality
It is not restricted to the described embodiments with novel, the above embodiments and description only describe the originals of the utility model
Reason, the utility model also has various changes and improvements on the premise of not departing from the spirit and scope of the utility model, these changes
Change and improvement is both fallen in the range of claimed invention.The utility model requires protection scope is by appended right
Claim and its equivalent define.
