[0003] However, in the existing hydraulic machinery, due to its traditional structural design, it is bulky and heavy, and the manufacturing cost is high; and its own control is limited by the characteristics of the drive motor and oil pump, so it inevitably inherits the traditional hydraulic power control. Disadvantages, such as low control precision, low efficiency and high energy consumption, and it is widely applicable, and the function is monotonous, and functions such as pressing, stretching, demoulding, and president cannot be realized at the same time; in addition, there are large heat generation, poor stability, and loud noise, etc. question

Abstract
The invention discloses a servo electrohydraulic composite pressure method, comprising the following steps: 1) arranging a stander; 2) arranging an upper hydraulic device on the stander, 3) arranging a closed ring servo electrohydraulic control system, wherein the closed ring servo electrohydraulic control system is connected with the upper hydraulic device, and controls the work situation of the upper hydraulic device; the invention further discloses a press machine which implements the method; the method provided by the invention uses a servo electrohydraulic technology to replace the traditional electrohydraulic control technology, which has simple manufacturing, high efficiency, little power consumption and high control precision; the position control precision can reach to 0.01 to 0.02 millimeters; the pressing, the tensioning, the de-molding, the full deciding and other functions can be realized simultaneously, so the method has a comparatively high processing flexibility; the press machine provided by the invention is rational in structure, little in volume, stable in work, high in capacity, little in noise, and wide in application range. The advantages of a mechanical punching machine, a hydraulic punching machine and a numerical control are integrated, so the press machine has the advantages of multi-function, low cost, large pressure tonnage, etc.
