In the above embodiment, the working principle of the adaptive lubrication system is as follows:
the press designer stores in advance in the data acquisition module 9 a correspondence table among the oil temperature C within the allowable temperature range of the press, the plunger actuation frequency S of the progressive distributor 4, and the operating frequency F of the variable frequency motor 1, the correspondence relationship among the three is determined by factors such as the oil outlet aperture of the progressive distributor, the power of the variable frequency motor, the material of a bearing bush at the moving position of the press, and the like, and the modification is not allowed after the factory setting is completed. When the press machine works, the temperature of lubricating oil output by the progressive distributor 4 is detected by the oil temperature sensor 6, a signal is sent to the data acquisition module 9, the data acquisition module 9 finds the closest oil temperature C from the prestored corresponding table after receiving the data of the actually measured oil temperature, the corresponding operating frequency F value of the variable frequency motor 1 is sent to the frequency converter 8 through the analog quantity output module 10, the operating frequency of the variable frequency motor 1 is controlled by the frequency converter 8, the output rotating speed of the variable frequency motor 1 is changed, the output flow of the lubricating pump 2 is changed along with the change of the rotating speed of the variable frequency motor 1, then the lubricating oil conveyed by the lubricating pump 2 pushes the plunger in the progressive distributor 4 to reciprocate the plunger, so that the accurate control of the actuating times of the progressive distributor is realized, and the progressive distributor 4 forces, quantificationally and controls the lubricating oil, The oil is sequentially conveyed to each part needing to be lubricated in each press, and the overflow valve 3 is ensured not to overflow in the process, so that the energy consumption utilization rate is improved, and the oil is energy-saving and environment-friendly; the overflow valve 3 can overflow only when the lubricating system has a fault and the pressure of an oil way is too high, so that the function of a safety valve is achieved, and all pipelines and elements of the lubricating system are protected.
Meanwhile, the actuation frequency of the progressive distributor 4 can be monitored, specifically:
the oil temperature sensor 6 sends the detected oil temperature to the data acquisition module 9 at intervals of a certain time (such as half an hour), meanwhile, the proximity switch 7 sends the detected actuation frequency of the progressive distributor 4 to the data acquisition module 9, the data acquisition module 9 finds the temperature C closest to the detected oil temperature from the prestored corresponding table, and outputs the plunger actuation frequency S value of the corresponding distributor to be compared with the detected actuation frequency of the distributor, if the two values are consistent (within a set range), the lubrication system works normally; if the two do not match, indicating that the plunger of the progressive distributor 4 is stuck or the line is clogged, a shut down is required to check the lubrication line and associated distributor elements.
