Abstract
The utility model discloses a control system for press machine slide block stopping top dead center position in the machine field, which comprises an electromagnetic speed adjusting motor and a PLC, and is characterized in that the signal of a three-phase AC speed measuring power generator in the electromagnetic speed adjusting motor is connected with the input end of an optical coupler after being sequentially and serially connected with a first current limiting resistor and a rectifying diode, and a frequency pulse signal is obtained after the output end of the optical coupler is serially connected with a second current limiting resistor to be accessed to a high-speed counting input port of the PLC. The PLC calculates the present speed of the electromagnetic speed adjusting motor according to the frequency pulse signal, and the stopping position of a slide block on the top dead center can be intelligently adjusted according to a preset program.
Description
Technical field
The utility model relates to a kind of forcing press, particularly a kind of control system of press ram stopping at certain point.
Background technology
A lot of punching machines use electromagnetic speed-adjusting master motors to realize regulating of the number of strokes, make in this way after, owing to the change of the number of strokes causes the inaccurate of slider stopping at certain point.At present need operating personnel according to the current number of strokes usually, adjust high low speed selector switch and send signal for Programmable Logic Controller (hereinafter to be referred as PLC), PLC adjusts stopping at certain point according to predefined program.So the control slider stopping at certain point is still not accurate enough, and can not realize Based Intelligent Control.
The utility model content
The technical problems to be solved in the utility model is, a kind of control system of press ram stopping at certain point is provided, can intelligence and accurately adjust slider stopping at certain point.
For solving above technical problem, the control system of a kind of press ram stopping at certain point provided by the utility model, comprise electromagnetic varispeed motor and PLC, three-phase alternating current tachometer generator signal in the described electromagnetic varispeed motor is connected behind first current-limiting resistance and the commutation diode successively, insert the input of optocoupler, the output of optocoupler is connected behind second current-limiting resistance, obtains the high-speed counting input port that the frequency pulse signal inserts PLC.
With respect to prior art, the utility model has been obtained following beneficial effect: be connected to the optocoupler input after the three-phase alternating current tachometer generator signal process current limliting rectification in the electromagnetic varispeed motor, the output signal of optocoupler is the rotational speed pulse signal of electromagnetic varispeed motor, PLC goes out the present speed of electromagnetic varispeed motor by this calculated signals, realizes that according to predefined program intelligence adjusts slider stopping at certain point.
Description of drawings
Fig. 1 is the schematic diagram of the control system of the utility model press ram stopping at certain point.
Among the figure: 1 three-phase alternating current tachometer generator signal, 2 first current-limiting circuits, 3 commutation diodes, 4 optocouplers, 5 second current-limiting resistances, 6 frequency pulse signals.
The specific embodiment
Electromagnetic varispeed motor is made up of common squirrel-cage asynchronous motor, electromagnetic slip clutch and three-phase alternating current tachometer generator.
As shown in Figure 1, in the control system of the utility model press ram stopping at certain point, three-phase alternating current tachometer generator signal 1 in the electromagnetic varispeed motor is connected behind first current-limiting resistance 2 and the commutation diode 3 successively, insert the input of optocoupler 4, the output of optocoupler 4 is connected behind second current-limiting resistance 5, obtains the high-speed counting input port that frequency pulse signal 6 inserts PLC.
Be connected to the optocoupler input after the three-phase alternating current tachometer generator signal process current limliting rectification in the electromagnetic varispeed motor, the output signal of optocoupler is the rotational speed pulse signal of electromagnetic varispeed motor, PLC goes out the present speed of electromagnetic varispeed motor by this calculated signals, according to predefined program the velocity interval of electromagnetic varispeed motor is divided into several intervals, and intelligence is adjusted slider stopping at certain point.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all fall into the protection domain of the utility model requirement.
