Brief description of the drawings
Fig. 1 is structure chart of the present utility model.
Embodiment
The utility model is further described with reference to specific embodiment and accompanying drawing.
A kind of high response charging device of large-scale high speed hydraulic press as shown in Figure 1, it includes main pressurization oil cylinder 10, and the master adds
The afterbody of compressing cylinder 10 is provided with liquid-filled tank 11, and has several be directly mounted on main pressurization oil cylinder 10 in the liquid-filled tank 11
Active control type replenishing valve 12, the control medium inlet of the active control type replenishing valve 12 and outlet are compiled in total feed tube, total
In liquid back pipe, and total feed tube connection constant pressure oil source, total liquid back pipe connects oil return box, on total feed tube, total liquid back pipe
It is provided with a proportional direction valve 13.
Liquid-filled tank 11 in the utility model is directly mounted at the afterbody of main pressurization oil cylinder 10, mechanically or other
