The servomotor that described Electrified Transmission comprises the miniature lever that is arranged on the operating desk, be fixed on photoelectric encoder on the miniature lever, collect the PLC of the pulse signal of photoelectric encoder conversion, driven by the servo controller and the servo controller of PLC control.
The beneficial effects of the utility model are, hydraulic press of the present utility model because the use UEFA Champions League of accumulator has improved the speed of forging, improves work efficiency, and its manipulations is light, sensitive, reliably, easily be automated.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, column, 2, entablature, 3, sill, 4, moved cross beam, 5, main allocated equipment, 6, pipeline, 7, water pump-accumulator transmission, 8, Electrified Transmission, 9, the hydraulic pressure water vat.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
The hydraulic press of preferred forms as shown in Figure 1, have four root posts 1, the top of four root posts 1 is entablature 2 fixedly, the bottom of four root posts 1 is sill 3 fixedly, the centre of four root posts 1 is provided with moved cross beam 4, be connected with hydraulic pressure water vat 9 on the moved cross beam 4, connect the pipeline 6 that has main allocated equipment 5 on the hydraulic pressure water vat 9, pipeline 6 is supplied with water under high pressure by water pump-accumulator transmission 7, advancing of pipeline 6 main allocated equipments 5, Electrified Transmission 8 controls of the switching of draining valve by having PLC, Electrified Transmission 8 comprises the miniature lever that is arranged on the operating desk, be fixed on the photoelectric encoder on the miniature lever, collect the PLC of the pulse signal of photoelectric encoder conversion, by the servo controller of PLC control and the servomotor of servo controller drive.
Hydraulic press has four root posts 1, the top of four root posts 1 is entablature 2 fixedly, the bottom of four root posts 1 is sill 3 fixedly, the centre of four root posts 1 is provided with moved cross beam 4, column 1 is fixedlyed connected with lower and upper cross-member 3 by nut, constitutes the enclosed framework, by the promotion of water under high pressure, the idle running of finishing moved cross beam 4 one-periods downwards, pressurization, backhaul and stop, thereby realize Forging Technology.
Be water pump-accumulator transmission 7 during work, water pump is given the water under high pressure of 32MPa altogether, becomes the power of press, owing to adopted accumulator, thereby has improved forging speed, and forging speed has to be brought up to about 65 times/minute for original 3～5 times/minute, improves work efficiency.
Water under high pressure promotes moved cross beam 4 by pipeline 6, main allocated equipment 5 is set on the pipeline 6, on the main allocated equipment 5 camshaft is arranged, cam is arranged on the camshaft, cam contacts with the spool of the reversal valve of main allocated equipment 5, move motion by the rotating band of cam, realize that reversal valve advances, the switching of draining to valve core.The rotation of cam is to realize by the rotation that Electrified Transmission 8 drives camshaft.
The servomotor that Electrified Transmission 8 comprises the miniature lever that is arranged on the operating desk, be fixed on photoelectric encoder on the miniature lever, collect the PLC of the pulse signal of photoelectric encoder conversion, driven by the servo controller and the servo controller of PLC control.People are downward according to the idle running of setting, pressurization, backhaul, stop four positions and move angle of miniature lever, 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 the servomotor running by servo controller, servomotor rotates by the camshaft that connects reductor deceleration back drive main allocated equipment 5 thereon, rotate the spool that pushes reversal valve by the cam on the camshaft, make and opened the intake tunnel or the drainage channel of reversal valve on the distributor, realize the motion of press moved cross beam 4.
