Judging whether the opening limit is larger than the current size, if so, issuing Zhang Mofa an opening instruction to the execution unit; if not, no action is performed; it is understood that the open instruction is issued Zhang Mofa to the execution unit only when the condition is reached, and if the condition is not reached, the open instruction is not issued Zhang Mofa, i.e., no action is taken.
Judging whether the target pressure value is larger than the current pressure value, if so, issuing a closing valve opening instruction to an execution unit; if not, the program is ended, the module is sent to complete the mark, and the operation is skipped to the operation maintaining module, so that the mode can be understood that the mode closing valve opening instruction is issued to the executing unit only when the condition is met, if the condition is not met, the mode closing valve opening instruction is not issued, namely, no operation is performed, and when the mode closing valve opening instruction is not required to be issued, the current pressure value reaches the target pressure value, and therefore the mark is completed by the sending module.
Optionally, in the intelligent control method of the buckling and pressing machine, if the machining target value is of a third type, a third execution module is called, and the execution steps of the third execution module are as follows:
Judging whether the opening limit is larger than the current size, if so, issuing Zhang Mofa an opening instruction to the execution unit; if not, no action is performed; it is understood that the open instruction is issued Zhang Mofa to the execution unit only when the condition is reached, and if the condition is not reached, the open instruction is not issued Zhang Mofa, i.e., no action is taken.

When such abnormal conditions occur, it is necessary to determine whether the limit size is greater than the current size or whether the limit pressure value is less than the current pressure value, if so, then the closing instruction of the mold clamping valve is issued to the execution unit, an abnormal flag is sent, and the operation is skipped to the operation maintaining module.
Preferably, in one embodiment, the invention can also be controlled manually, namely, the upper computer sends an opening valve opening instruction to the execution unit by manually pressing the mold opening button; or manually pressing a mold closing button, and the upper computer gives a mold closing valve opening instruction to the execution unit.
Preferably, after the jump to the action maintaining module, the manual command Zhang Mofa and/or the closing valve opening command are/is invalid, so as to avoid errors in the production process caused by manually opening or closing the valve when no execution module is executed.
Optionally, in S2 of the present invention, the micro control unit of the upper computer invokes all the adjustment parameters, converts all the adjustment parameters into the sensor voltage values, and transmits the converted adjustment parameters to the lower computer through the communication device.
