23 and second the cavity of resorption of auxiliary oil cylinder 24 be connected with the accumulator 19 of peripheral hardware simultaneously.
In the hydraulic system of the present invention, further scheme is, at the output of described first branch line 27 also with
Two inserted valves 4 connect, and the epicoele of described second inserted valve 4 is connected with proportional pressure control valve 6.Described first inserted valve 7,
And second be provided with cover plate 8 on inserted valve 4.Also set up between the input/output terminal of described 3rd Solenoid ball valve 16
There is the second stop valve 17.
Its operation principle is as follows:
(1) pump start
Pressing motor 1 start button, oil pump 2 starts, owing to lathe is in the state of off-load, oil pump 2 out hydraulic pressure
Oil flows back to fuel tank 5 through the second inserted valve 4.
(2) lathe is sheared
After oil pump 2 starts, step on floor push, then proportional pressure control valve 6 obtains electric, and hydraulic system sets up pressure, pressure oil one
Road enters binder cylinder 20, pushes down by shear material, and a road then enters the epicoele of first, second master cylinder 21,22, first,
