In the working chamber for making cylinder structure 9, the output corresponding sports of work cylinder structure are controlled to apply pressure, the high pressure of formation to workpiece
Oil liquid is up to 150MPa, due to being pressurizeed using servo motor cooperation screw press device combination, it can be achieved that servo pressurization, pressure control
Precision is less than 0.1MPa, can realize linear pressurization.
Backhaul: in pressure release backhaul, as needed there are two types of mode it can be selected that being depressured one is slope is not needed, one
Kind is that slope is needed to be depressured.
When not needing slope decompression, using being directly depressured, manually unloading pressure control valve 8 is opened first at this time, and realization is let out
Pressure, waits the manually linear opening of relief valve 13, while the starting of Special-purpose motor for oil pump 2 after the completion of pressure releases, and the stopping of servo motor 18 is filled
Liquid reversal valve 6 is powered, and is in backhaul station shown in Fig. 2, and low pressure oil liquid enters working cylinder knot by filter 4, filling liquid reversal valve 6
The hydraulic oil liquid of the reseting cavity of structure 9, the working chamber for the cylinder structure that will work enters fuel tank through manually unloading pressure control valve valve 8, complete
At return stroke.
When needing slope to be depressured, manually linear relief valve 13 is opened first, while Oil pump electrical machinery 2 starts, and two four
Electric change valve 6 is powered, and is in backhaul station shown in Fig. 2, and low pressure oil liquid enters work by filter 4, filling liquid reversal valve 6
In the reseting cavity of cylinder structure 9, the super-pressure oil liquid in the working chamber of cylinder structure 9 that works handles dynamic linear relief valve 13 and spiral
The linear change volume of pressurizer 16 is connected, and servo motor 18 inverts at this time, drives screw press device by accurate retarding machine 19
16 interior direct acting part moves down, linear change volume it is linearly increasing, and then realize slope decompression, due to use servo motor
The mode for adding screw press device to combine is depressured, it can be achieved that system slope is depressured, and slope is depressured after completion, manually pressure release
Control valve 8 is opened, and the hydraulic oil of the working chamber for the cylinder structure 9 that works enters fuel tank through manually unloading pressure control valve 8, realizes that pressure release is returned
Journey.
In the present embodiment, by controlling servo motor positive and negative rotation, the reciprocal shifting of the interior direct acting rod piece of screw press device is realized
It is dynamic, and then realize that the linear increase of the linear change volume of screw press device and linear reduction, linear change volume herein refer to
Be its volume variation it is linear (a little error does not count), and then can realize linear pressurization and linear voltage decreasing requirement,
Whole control is relatively simple, and slope decompression, Costco Wholesale is relatively low, and oil temperature is relatively low, also, is utilized and manually controlled realization
The switch motion of corresponding unloading pressure control valve and linear relief valve, realizes while having the large scale of quick pressure releasing and slope pressure release
