The automatic pressure adjusting system comprises a press air storage tube, a programmable logic controller (PLC), a touch screen, a pressure relay, an air inlet solenoid valve and an air exhaust solenoid valve. The press air storage tube is connected with an air inlet pipeline and an air exhaust pipeline, and the pressure relay used for detecting pressure of the press air storage tube is arranged on the press air storage tube. The signal output end of the pressure relay is connected into the signal input end of the PLC, an output module of the PLC controls the air inlet solenoid valve and the air exhaust solenoid valve to be opened and closed, the air inlet solenoid valve is arranged on the air inlet pipeline, the air exhaust solenoid valve is arranged on the air exhaust pipeline, and a signal line of the touch screen is connected into a communication interface of the PLC. When the pressure value in the press air storage tube is lower than the set lower limit value, the PLC controls the air inlet solenoid valve to be opened to be inflated; and when the pressure value in the press air storage tube is higher than the set upper limit value, the PLC controls the air exhaust solenoid valve to be opened to release pressure. The automatic pressure adjusting system is simple in structure, low in cost and reliable in control.
Description
Technical field
The utility model relates to a kind of control system of forcing press, particularly a kind of press machine pressure automatic regulating system.
Background technology
Because press balance cylinder air pressure becomes a kind of proportionate relationship of linearity with slide block patrix weight, therefore need to carry out air pressure adjustment according to different moulds.Equally, when using air cushion, the difference of air cushion atmospheric pressure value can cause the ejecting force of air cushion to change.In order to make forcing press often be in optimum Working, the adjusting of pressing for the gentle cushion steam of press balance cylinder air pressure seems particularly important.In addition, in the lathe course of work, the atmospheric pressure value that causes regulating owing to constantly air inlet, exhaust meeting changes, so the automatic adjusting of air pressure is more crucial.
Realize in the prior art that the key element that air pressure is regulated automatically is proportioning valve, but the air pressure fluctuation during owing to lathe work is larger, therefore can cause proportioning valve working without cessation, after a period of time, Frequent Troubles brings very large inconvenience and serious consequence for the use of forcing press.
