Dead point, releases binder.This kind of mode, can individually control binder cylinder 16 carries out binder, and binder pressure adjustable, in pressure gauge II
Pressure value is shown on 25, adapts to the compression demand of different length and thickness plate, especially when overlength plate cutting is to line, this work(
Can be highly useful.
3. shear (knife rest is descending)
YV0, YV3 obtain electric, and pressure oil initially enters binder cylinder 16, and 16 descent of piston of binder cylinder compresses plate, when system pressure
Power exceedes the setting pressure of sequence valve 11, i.e. 8MPa, pressure oil Jing sequence valve 11 enters the rodless cavity of master cylinder 18, due to main oil
The rod chamber of cylinder 18 is connected with the rodless cavity of auxiliary oil cylinder 19, so master cylinder 18 and the synchronous of auxiliary oil cylinder 19 drive knife rest descending,
And hydraulic oil is pressed in accumulator 14 in 15 rod chamber of backhaul oil cylinder, 15 rodless cavity of backhaul oil cylinder suction air, accumulator 14
The interior air bag full of nitrogen is compressed, and is the backhaul accumulation of energy of knife rest.
4. backhaul (knife rest is up)
YV2 obtains electric, other electromagnetic valve power-off, under the pulling force effect of 16 spring of binder cylinder, hydraulic oil quilt in binder cylinder 16
Release oil sump tank 1,16 backhaul of binder cylinder unclamp plate；Meanwhile, 18 rodless cavity of master cylinder is also opened to the passage of fuel tank 1, is stored
Nitrogen pressure release action in energy device 14, the hydraulic oil being gathered in accumulator 14 start to drive 15 rod chamber of backhaul oil cylinder to live
Plug, promotes knife rest up, and 15 rodless cavity air-out of backhaul oil cylinder is until top dead-centre.
5. the knife rest angle of shear reduces
YV0 and YV1 obtain electric, open stop valve II 17, and pressure oil Jing switch valves 10 enter the rod chamber of master cylinder 18 and pair
The rodless cavity of oil cylinder 19,19 piston of auxiliary oil cylinder start it is descending, knife rest under the driving of auxiliary oil cylinder 19 and workbench angle gradually
Reduce；After YV0 and YV1 power-off, master cylinder 18 and auxiliary oil cylinder 19 are locked, and the knife rest angle of shear is fixed, and close stop valve
II 17, complete angle of shear reduction action.In actual use, shearing thin plate needs to reduce the angle of shear, is conducive to improving production effect
Rate.
6. knife rest angle of shear increase
YV1 obtains electric, opens stop valve II 17, the quilt under the driving of backhaul oil cylinder 15 of the hydraulic oil in 19 rodless cavity of auxiliary oil cylinder
Fuel tank 1 is pushed back, 19 piston stroking upward of auxiliary oil cylinder, knife rest gradually increase with the angle of workbench under the driving of auxiliary oil cylinder 19；Work as YV1
Power-off, master cylinder 18 and auxiliary oil cylinder 19 are locked, and the knife rest angle of shear is fixed, and close stop valve II 17, complete angle of shear increase
Action.In actual use, when shearing thicker plate, need to increase the angle of shear, improve shear ability.
7. accumulator topping up
YV0 obtains electric, and system sets up pressure, and the supercharging pressure for adjusting sequence valve 11 is 12～16MPa, opening stop valve I 9,
Now system pressure oil Jing stop valves I 9 enter the grease chamber of accumulator 14, and in backhaul oil cylinder 15, hydraulic fluid pressure becomes larger, knife
Frame is slowly risen until top dead-centre under the active force of backhaul oil cylinder 15；After pressure reaches the supercharging pressure of the setting of sequence valve 11
Pressure value tends towards stability, now quick closedown stop valve I 9, terminates 14 topping up of accumulator, again the work pressure of setting up sequence valve 11
Power completes 14 topping up of accumulator to 8MPa.This kind of frame mode, it is when equipment breaks down, convenient to overhaul.
8. oil cylinder topping up
Stop valve I 9 is opened, the hydraulic oil discharged in accumulator 14 makes to drop down onto lower dead center under knife rest, opens stop valve II 17,
Again the bleed screw at the top of auxiliary oil cylinder 19 is unclamped slightly, starts oil pump 5, YV0 and YV1 obtains electric, hydraulic oil enters main oil
In the rodless cavity of the rod chamber of cylinder 18 and auxiliary oil cylinder 19, bleed screw is monitored, begin with when fluid is overflowed from bleed screw and suspend
Liquid-filled operation, proceeded liquid-filled operation after five minutes, was repeated several times above operation, until air vent does not have gas to discharge, i.e.,
Represent in oil cylinder and have been filled with fluid, finally bleed screw is locked.
Lock formula hydraulic system of cutting machine of the present utility model, compared to existing hydraulic system of cutting machine, structure is significantly simple
Change, reduce pipeline arrangement, components and parts can be focused on an integrated valve block, and structure is compacter, the plate shearing machine phase with same specification
More than 2.4% can be reduced than overall weight, plate shearing machine cost reduces at least 4%, and system acting is sensitive, No leakage, working stability
