Embodiment Construction

[0013] The proportional oil control and water control system of the die forging hydraulic press of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so as to help understand the content of the present invention.

[0014] As shown in Figure 1, it is a schematic diagram of the drive mechanism of the dispenser. It includes a servomotor 1, a camshaft 3, a cam 2, a push rod 4, an adjusting nut 5, a flexible coupling 6, a rotation angle detection device 7, and a distributor valve body 8. As shown in FIG. 2 , the middle section of the piston rod 9 in the servomotor oil cylinder is made into a rack 10 , the rack 10 and the gear 11 form a rack-and-pinion transmission, and the gear 11 is installed on the camshaft 3 .

[0015] As shown in Figure 3, it is a schematic diagram of the principle of the hydraulic drive circuit. The hydraulic drive circuit is mainly composed of a pump station 14, an electro-hydraulic pr...

Abstract

The invention discloses a die forging hydraulic machine proportional oil-control-water operate system. It includes hydraulic drive loop, servomotor cylinder, ram, cam, rotate angle detection device and controller; said hydraulic drive loop consists of main oil way and control oil way which is composed by pumping plant, one electrohydraulic ratio choke valve and two two-position three-way valves and four plug-in cone valve; the input of said controller is connected with said rotate angle detection device, the output of controller is connected with electrohydraulic ratio choke valve to adjusting the quantity of hydraulic drive loop basing the input signals and according rate and connected with two two-position three-way valves to control the big flow direction of hydraulic cylinder through the control of make and break of two-position three-way valves. The die forging hydraulic machine proportional oil-control-water operate system has advantages of high precision and good stability.

Description

technical field [0001] The invention relates to a giant hydraulic press control system, in particular to a proportional oil control water control system for a giant die forging hydraulic press. Background technique [0002] The giant die forging hydraulic press is the key equipment of a country's national defense and basic industries, and plays an important role in national defense and infrastructure construction. The control system of the hydraulic press is a control mechanism that completes various strokes and actions of the hydraulic press and its auxiliary mechanisms, and is an important part of the hydraulic press. [0003] At present, the control system of giant die forging hydraulic presses at home and abroad mostly adopts the "water control" method, that is, a mechanical large lever is used, and the operator pulls the lever through a series of lever mechanisms to make the distributor valve core control mechanism in the corresponding position. position, so as to comp...
