Description
Technical field
The present invention relates to a kind of supporting plate jacking system, the jack-up for being particularly suitable for moveable platform of press supporting plate falls.
Background technology
High-end mobile work platform generally configures inner shoe, and for holding up cylinder assembly, user is usually and rushes per platform its control unit
Pressure equipment is equipped with many molds, and per mold, corresponding ejector beam arrangement is different, and quantity is also different, during more mold exchange, faces
Easily tens kilograms, when dropping off bar of large area layout is necessarily wasted time and energy using the artificial ejector beam that takes out, have impact on work effect
Rate.
Content of the invention
The technical problem to be solved is the defect existed for prior art, there is provided a kind of safe and reliable
Ejector beam automatic ejection.
For solving this technical problem, the invention provides jacking system in a kind of mobile work platform supporting plate machine, including work
Make platform, supporting plate and supporting plate jack-up cylinder, the supporting plate jack-up cylinder includes holding up cylinder body, gland, plunger and sealing ring, in the plunger
Oil pocket is provided with, sealing ring and sealing ring circle back-up ring form closed oil pocket, plunger and picking-up by the top that gland is fixed on plunger
Coordinated by gap between cylinder body and be assembled together；The plunger is fixed with workbench, the boss on the outside of supporting plate and picking-up cylinder body
Connection；Low-power machine drives gear pump to provide power for supporting plate jack-up cylinder, and the motion of cylinder body drives supporting plate to rise；During falling,
The commutation of the two-position four-way solenoid valve being arranged on oil circuit makes pressure oil unload to fuel tank, completes under supporting plate and push rod action of gravity
Descending action.
Hole depth control of the stroke for holding up cylinder body by the jacking hole of workbench bottom surface.
The sealing ring is y-type seal ring.
Beneficial effect：The present invention is suitable for moveable platform of press supporting plate using from by the way of internal piston fuel feeding
Jack-up falls, and solves the problems, such as that press bench manually takes ejector beam, overcomes the manual border for exiting ejector beam, with knot
Structure is simple, save space, easy for installation, reduction labor intensity, the advantage of high working efficiency.
Description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the control principle drawing of the present invention；
Fig. 3 is the practical application schematic layout pattern of the present invention.
In figure：1 holds up cylinder body, 2 glands, 3 plungers, 4 supporting plates, 5 oil-ins, 6 workbench, 7 jacking holes, 8 supporting plate jack-up cylinders.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is specifically described to the present invention.
Fig. 1 show the structural representation of the present invention.
The present invention includes workbench 6, supporting plate 4 and supporting plate jack-up cylinder 8.
The supporting plate jack-up cylinder 8 includes holding up cylinder body 1, gland 2, plunger 3 and sealing ring 4.
Oil pocket is provided with the plunger 3, oil-in 5 is arranged on oil pocket lower end, and the plunger 3 is fixed with workbench 6.
The gland 2 is used for the top that sealing ring 4 and sealing ring circle back-up ring are fixed on plunger 3, to form closed oil pocket.
Coordinated by gap between the plunger 3 and picking-up cylinder body 1 and be assembled together, play guide effect.
Shown supporting plate 4 is connected with the boss held up on the outside of cylinder body 1.
The bottom surface of the workbench 6 is provided with jacking hole 7, and the stroke for holding up cylinder body 1 is controlled by the hole depth in the jacking hole 7.
The sealing ring 4 is y-type seal ring.
Fig. 2 show the control principle drawing of the present invention.
The supporting plate jack-up cylinder 8 drives gear pump to provide power for which by low-power machine, and lifting power is hydraulic coupling,
Realize by gravity when falling.
The supporting plate jack-up cylinder 8 of the present invention is different from traditional cylinder apparatus, plunger body fuel feeding, and plunger 3 is solid with workbench 6
Fixed, drive supporting plate 4 to rise by the motion of cylinder body 1；When needing to fall, the two-position four-way solenoid valve being arranged on oil circuit commutates,
Pressure oil is unloaded to fuel tank, completes descending action, return to home position under supporting plate 4 and push rod action of gravity.
Fig. 3 show the practical application schematic layout pattern of the present invention.
Using from by the way of internal piston fuel feeding, the jack-up for being suitable for moveable platform of press supporting plate falls the present invention,
Solve the problems, such as that press bench manually takes ejector beam, overcome the manual border for exiting ejector beam, with simple structure, section
Save space, easy for installation, reduction labor intensity, the advantage of high working efficiency.
The embodiment above of the present invention, is merely illustrative, be not only, all within the scope of the present invention or equivalent this
Change in the range of invention is surrounded by the present invention.
