Description
Technical field
The utility model belongs to mechanical control technology field, relates to a kind of four-column hydraulic press and automatically controls systemSystem.
Background technology
Four-column hydraulic press is prepared the course of work of drawing part, at present by manual operation, after primer fluid pressObserve drawing stroke by eyes, in the time that drawing arrives precalculated position, artificial stop solution press. But completelyManual operation there is following defect: 1) manual operation, easily cause maloperation, jeopardize workman's personSafety; 2) do not eject safety caging device, likely can cause the damage to hydraulic press itself; 3)Labor strength is large, withered hot-tempered, and when hydraulic press work, workman must stare at drawing stroke the moment and see, holdsEasily cause fatigue; 4) manual observation drawing stroke, error is large, and precision is low, and drawing part qualification rate is low; 5)Manual operation required time is long, qualified drawing part of drawing, and the extra time of cost is longer,Waste electric power resource.
The frauds such as the potential safety hazard that exists in view of above-mentioned manual operation is large, product percent of pass is low, the wasting of resources is manyEnd, proposes the design of automatic control to four-column hydraulic press.
Utility model content
The purpose of this utility model is to provide a kind of four-column hydraulic press automatic control system, has solved existing fourColumn hydraulic machine is prepared drawing part, completely manual operation monitoring, and the potential safety hazard brought is large, product is qualifiedThe problem that rate is low, the wasting of resources is many.
The technical scheme that the utility model adopts is that a kind of four-column hydraulic press automatic control system, comprisesController, controller is connected with signal conditioner and displacement transducer successively, controller also respectively with pumpMachine, hydraulic press upload control device are connected with line control unit under hydraulic press, are provided with start button on controller.
Feature of the present utility model is also,
Controller is connected with voice prompting device.
On controller, be provided with the button that makes zero.
Controller is PLC controller, and its model is SIEMENSDM812/24R.
Signal conditioner model is DIN12-IRT.
Displacement transducer is grating scale displacement transducer, and its model is D60S2M.
Voice prompting device model is DLT200.
The beneficial effects of the utility model are that the utility model four-column hydraulic press automatic control system, adoptsPLC controls hydraulic press operation automatically, automatically completes the drawing work of blank, reduces labor strength,The danger of avoiding artificial incorrect operation to bring; Realize the high accuracy stroke monitoring of drawing process simultaneously, improvedDrawing part qualification rate, has reduced drawing man-hour, has improved operating efficiency, has good energy conservation effectShould.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of four-column hydraulic press automatic control system of the utility model.
In figure, 1. controller, 2. information conditioner, 3. displacement transducer, 4. pump machine, 5. upload control device,6. descend line control unit, 7. voice prompting device, button, 9. start button 8. make zero.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The structure of a kind of four-column hydraulic press automatic control system of the utility model as shown in Figure 1, comprises controlDevice 1, controller 1 is connected with signal conditioner 2 and displacement transducer 3 successively, and controller 1 is also distinguishedBe connected with line control unit 6 under pump machine 4, hydraulic press upload control device 5 and hydraulic press, on controller 1, establishBe equipped with start button 9.
Its middle controller 1 is connected with voice prompting device 7; On controller 1, be provided with the button 8 that makes zero; ControlDevice 1 processed is PLC controller, and its model is SIEMENSDM812/24R; Signal conditioner 2 typesNumber be DIN12-IRT; Displacement transducer 3 is grating scale displacement transducer, and its model is D60S2M;Voice prompting device 7 models are DLT200.
Grating scale is in order to measure and to show the movement travel of hydraulic press. The output signal of grating scale comprises twoThe square-wave signal that road phase phasic difference is 90 °, can obtain displacement signal and direction of motion signal after by analysis. LightThe precision of grid chi displacement signal is 0.005mm.
Automatic control system is taken out and is drawn two-way voltage-type square-wave signal from the signal of grating scale output, to originalGrating scale and digital display meter can not cause interference.
The signal that displacement transducer 3 detects, after signal conditioner 2 conditionings, obtains being applicable to controllingThe displacement signal of device 1 and direction of motion signal, and flow to controller 1, controller 1 is according to receivingSignal, the operation of line control unit 6 under control pump machine 4, hydraulic press upload control device 5 and hydraulic press,And then complete the control to hydraulic press movement velocity and the direction of motion. The displacement signal essence of input control device 1Degree is not less than 0.08mm.
The button 8 that makes zero be one can Self-resetting press button, for demarcating hydraulic press drawing strokeZero-bit. Manually allow hydraulic press move to zero-bit, press next time " button makes zero ", the position in controller 1The amount of moving is just forced to be set to zero.
Start button 9 is the switches with auto-lock function, for the startup of hydraulic press with stop automaticallyOperation. When connection, controller 1 is controlled hydraulic press automatic operation; When disconnection, hydraulic press stops fortune immediatelyMoving.
Controller 1, by the control that pump machine 4 is moved and stopped, being realized the control to hydraulic press movement velocitySystem. When pump machine 4 moves, hydraulic press movement velocity is fast, and when pump machine 4 stops, hydraulic press movement velocity is slow.
Under hydraulic press upload control device 5 and hydraulic press line control unit 6 be hydraulic press from provided with electromagnetic valve, controlDevice 1, by the connecting and disconnecting to respective electrical magnet valve, is realized the control to hydraulic press traffic direction, connectsTime hydraulic press move to respective direction, shutoff is hydraulic press stop motion.
When work, after four-column hydraulic press energising, first manually adjusted to benchmark zero-bit, pressed automaticallyThe button 8 that makes zero of control system, by the displacement zero clearing in system; Then manually hydraulic press is adjusted toExtreme higher position, and place drawing plate, press start button 9, displacement transducer 3 detects hydraulic pressDisplacement signal, and show, the signal detecting is transferred to signal conditioner 2 by simultaneous displacement sensor 3,Signal transfers to controller 1 after conditioning, the data that controller 1 basis receives, control pump machine 4,Under hydraulic press upload control device 5 and hydraulic press, the operation of line control unit 6, carries out drawing work. Work as drawingWhen moulding, controller 1 is controlled voice prompting device 7 and is sent prompt tone, prompting operation person's feeding and reloading.
