Abstract

The invention relates to a hydraulic control system of a high-speed performing hydraulic machine. The hydraulic control system is characterized by comprising a power source circuit, an operating cylinder oil supply circuit and a control oil circuit, wherein the power source circuit comprises a pump source, a piston type energy accumulator group and a first pressure sensor; the operating cylinder oil supply circuit comprises a proportional cartridge valve, a first direction control two-way cartridge valve, a second two-position two-way direction valve, a first shuttle valve, a first pressure control two-way cartridge valve, a second proportional overflow valve, a first two-position two-way direction valve, a second direction control two-way cartridge valve, a third two-position two-way direction valve, a second shuttle valve, a second pressure control two-way cartridge valve, a first proportional overflow valve and a prefill valve; and the control oil circuit comprises a third pump source, a fifth two-position two-way direction valve, a one-way valve, a fourth two-position two-way direction valve, a bladder type energy accumulator, an energy accumulator safety valve group, a proportional two-way cartridge valve and a second pressure sensor. The hydraulic control system has the advantages that the operating speed of the hydraulic machine can be increased, and the quality of a workpiece is ensured.

Description

technical field [0001] The invention belongs to the hydraulic field of hydraulic presses, in particular to a hydraulic control system for high-speed preformed hydraulic presses. Background technique [0002] In the field of hydraulic press manufacturing, improving work efficiency and ensuring the quality of parts is the relentless pursuit of hydraulic press equipment. In the design and manufacture of domestic preforming presses, the fast-moving speed and working speed of the hydraulic press are restricted, and the installed power must be increased to increase the speed of the press. In the process of pressing the workpiece by the hydraulic press, the setting of the pressure in the two chambers of the oil cylinder determines the quality of the pressed workpiece. In the process of pre-forming processing and pressing, the stable forming force of the hydraulic press is the guarantee of the quality of the workpiece. In an automated production line, smooth and fast work is parti...
