Description
Technical field
The present invention relates to the hydraulic press technical field, the hydraulic press that especially a kind of new pure Electrified Transmission is operated.
Background technology
Press refers to be used for a kind of forming machine of industrial product by pressure forming.Commonly used is hydraulic press and hydraulic press at present, the moved cross beam of hydraulic press is to rely on " main allocated equipment " enterprising, the switching of valve realizes, the switching of these valves is again to rely on the main allocated equipment to control, the rotation of opening and closing of drain valve camshaft (or rocking bar) realizes, the hydraulic press in past is to handle the workman to move handle, pass through leverage, camshaft is rotated, very heavy, the increase that had afterwards waterpower or oil pressure servomotor, but still be very heavy, slow movement, handled hydraulic press afterwards and the electro hydraulic valve servo-drive system occurred, promptly increased by a cover auxiliary oil pump station, pushed distributor axis (or direct overhead-valve) by oil cylinder piston, not only numerous and diverse but also because of the uneasy congruent shortcoming of leakage of oil, perplexing the manipulation of hydraulic press all the time.
Summary of the invention
The technical problem to be solved in the present invention is: for shortcoming and the deficiency that solves above-mentioned existence, provide a kind of hydraulic press of Electrified Transmission.
The technical solution adopted for the present invention to solve the technical problems is: a kind of hydraulic press of Electrified Transmission, comprise moved cross beam and drive the control device that moved cross beam moves, control device has hydraulic circuit on the hydraulic pressure water vat that is connected on the crossbeam, be arranged on the main allocated equipment on the hydraulic circuit and the electric actuator of control main allocated equipment action, electric actuator comprises the closed-loop control system that contains PLC, weighs motion by the switching drive activity of the advancing of electric actuator control main allocated equipment, valve.
Described electric actuator comprises miniature lever, operating desk and closed-loop control system, the servomotor that closed-loop control system comprises the photoelectric encoder that is fixed on the miniature lever, is arranged on the PLC of the pulse signal of collecting the photoelectric encoder conversion on the operating desk, driven by the servo controller and the servo controller of PLC control.
The action of described electric actuator control main allocated equipment realizes that for the camshaft of electric actuator control connection on main allocated equipment cam is set on the camshaft, and cam contacts with the spool of main allocated equipment reversal valve.
Described closed-loop control system also comprises and being arranged on the camshaft to detect the encoder of the camshaft anglec of rotation.
The invention has the beneficial effects as follows, the hydraulic press of Electrified Transmission of the present invention, employing be pure Electrified Transmission because the closed-loop control system of PLC, make and handle lightly, sensitive, reliably, easily be automated.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is an electrical installation schematic diagram of the present invention.
Among the figure 1, moved cross beam, 21, hydraulic circuit, 22, main allocated equipment, 23, operating desk, 24, servomotor, 25, camshaft, 26, cam, 27, encoder, 28, the hydraulic pressure water vat.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
The hydraulic press of the Electrified Transmission of preferred forms as shown in Figure 1 and Figure 2, comprise moved cross beam 1 and drive the control device that moved cross beam 1 moves, control device has hydraulic circuit 21 on the hydraulic pressure water vat 28 that is connected on the crossbeam, be arranged on the main allocated equipment 22 on the hydraulic circuit 21 and the electric actuator of control main allocated equipment 22 actions, and electric actuator comprises the closed-loop control system that contains PLC.
Electric actuator comprises miniature lever, operating desk 23 and closed-loop control system, miniature lever is installed on the operating desk 23, the servomotor 24 that closed-loop control system comprises the photoelectric encoder that is fixed on the miniature lever, is arranged on the PLC of the pulse signal of collecting the photoelectric encoder conversion on the operating desk 23, driven by the servo controller and the servo controller of PLC control.
22 actions of electric actuator control main allocated equipment realize for the camshaft 25 of electric actuator control connection on main allocated equipment 22, cam 26 is set on the camshaft 25, because main allocated equipment 22 is a reversal valve, so cam 26 contacts with the spool of main allocated equipment 22 reversal valves.
Closed-loop control system also comprises and being arranged on the camshaft 25 to detect the encoder 27 of camshaft 25 anglecs of rotation.
People are airborne according to what set, pressurization, stop, angle of miniature lever is moved in four positions of backhaul, photoelectric encoder is an optical signal with the angle signal collection then, photoelectric encoder is sent into PLC after converting optical signal to pulse signal, handle back voltage signal of output through PLC and remove to control servo controller, drive servomotor 24 runnings by servo controller, servomotor 24 rotates by 2 25 on the cam that connects reductor deceleration back drive main allocated equipment 22 thereon, rotate the spool that pushes reversal valve by the cam on the camshaft 25 26, feasible intake tunnel or the exhalant canal of having opened the distributor reversal valve realized the motion of press moved cross beam 1.
Simultaneously, after camshaft 25 rotates, be arranged on the anglec of rotation that encoder 27 on the camshaft 25 has detected camshaft 25, encoder 27 is with the signal back PLC that collects, and compare with the data that miniature lever provides this moment, finish the Position Control of servomotor 24, make main allocated equipment 22 camshafts 25 corner accuracies be ± 0.5 °, promptly the moving motor that drives of miniature lever moves, and it is moving to drive camshaft 25 simultaneously, miniature lever stops making motor to stop while camshaft 25 and stops, with motion tracking.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
