Abstract
A kind of metal hydrostatic extruder return device of rapid, including master cylinder, master cylinder side is provided with the prefill valve for drain, master cylinder is internally provided with main plunger, the plunger case respectively arranged up and down in main plunger, master cylinder is internally provided with main plunger, it is disposed on plunger case and returns to plunger, plunger end is returned to be connected with baffle, baffle is in contact with extrusion cylinder, returning to plunger, arrangement is built in main plunger up and down, plunger end is returned to be connected with baffle, plunger cavity oil inlet is returned to when returning to, it returns to piston rod and baffle is squeezed the hydraulic medium promotion main plunger retrogressing for returning to plunger cavity after pressure cylinder stops, prefill valve opens master cylinder drain simultaneously, realize quick return, the present invention improves the working efficiency of metal hydrostatic extruder, reduce the geometric dimension and weight of extruder, reduce the cost of hydrostatic extruder.
Description
Technical field
The present invention relates to technical field of metallurgical equipment, in particular to a kind of metal hydrostatic extruder return device of rapid.
Background technique
For metal hydrostatic extruder using plunger case as Main cylinder, the area in extruding engineering due to Main cylinder is remote
Much larger than the area of extrusion cylinder inner section, become booster body, super super-pressure is generated in extrusion cylinder, realizes difficult deformable metal
The forming of superplasticity hydrostatic extrusion.Terminate in extruding, Main cylinder needs quick return, to improve the work effect of hydrostatic extruder
Rate, it is therefore desirable to efficient Main cylinder return device of rapid.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide a kind of metal hydrostatic extruder is quick
Return facilities make to push main plunger in master cylinder backhaul in the plunger case for respectively arranging a minor diameter up and down of Main cylinder plunger
It quickly retracts, that realizes main operating cylinder quick and stable returns to initial position.
To achieve the goals above, the technical solution adopted by the present invention is that:
A kind of metal hydrostatic extruder return device of rapid, including master cylinder 5,5 side of master cylinder are provided with filling for drain
Liquid valve 6, master cylinder 5 are internally provided with main plunger 4, the plunger case respectively arranged up and down in the main plunger 4, in the master cylinder 5
Portion is provided with main plunger 4, is disposed on plunger case and returns to plunger 3, returns to 3 end of plunger and is connected with baffle 2, baffle 2 and extruding
Cylinder 1 is in contact.
The diameter of the plunger case is 1530mm.
The plunger cylinder is mounted on main plunger 4, and 4 one end of main plunger and extrusion cylinder 1 are rigidly connected.
Beneficial effects of the present invention:
The plunger case of a minor diameter is respectively arranged in about 5 hydrostatic extruder master cylinder, plunger cylinder is mounted on main plunger 4
On, 4 one end of main plunger and extrusion cylinder 1 are rigidly connected, in the case where hydrostatic extrusion terminates and master cylinder 5 is needed to retract, two
Plunger case injection pressure liquid, plunger case area of section is small so that can be pushed under same flow with faster speed main plunger 4 from
It opens extrusion cylinder and realizes quick return, smoothly return to the position for needing to retract.
The present invention use arrangement symmetrical above and below small plunger diameter cylinder, can main plunger 4 being retracted with quick and stable, realize
The quick return of main plunger 4 improves the working efficiency of metal hydrostatic extruder；This structure reduce extruder geometric dimension and
Weight reduces the cost of hydrostatic extruder.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, the plunger case respectively arranged up and down in main plunger 4 terminates in hydrostatic extrusion and master cylinder 5 is needed to return
In the case where moving back, main plunger 4 is pushed to leave extrusion cylinder 1 and backhaul；The plunger case respectively arranged up and down in main plunger 4, plunger case
It is the smaller plunger case of diameter；Pillar plug cylinder above and below in main plunger 4, plunger cylinder are mounted on main plunger 4, main plunger
4 one end and extrusion cylinder 1 are rigidly connected；Injection pressure liquid, promotion main plunger 4 leave extrusion cylinder to two plunger cases simultaneously when backhaul
1 and backhaul.
The working principle of the invention:
It returns to about 3 plunger arrangement to be built in main plunger 4, returns to 3 end of plunger and be connected with baffle 2.It is returned to when returning to
3 chamber oil inlet of plunger, returns to piston rod and baffle 2 is squeezed the hydraulic medium promotion main plunger 4 that plunger cavity 3 is returned to after pressure cylinder 1 stops
It retreats, while prefill valve 6 opens 5 drain of master cylinder, realizes quick return.
