Description
Technical field
The present invention relates to technical field of metallurgical equipment, in particular to a kind of metal hydrostatic extruder extruded product buffering dress
It sets.
Background technique
Metal hydrostatic extruder is to carry out superplastic extrusion processing, fluid pressure to difficult deformable metal under high pressure
Up to 1800MPa.Herein in the case of super super-pressure, the extruded product of extrusion needs reliable reception device, by hydrostatic extrusion system
The reception of product safety；Due at the end of extruding sometimes with the release of high squeeze pressure, it is therefore desirable to special buffering dress
It sets to receive the extruded product of extrusion.
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 extrusions
Product buffer unit is provided with filling liquid buffer unit in metal hydrostatic extruder front-axle beam exit, squeezes via super super-pressure hydrostatic
The extruded product of pressure superplastic deformation directly extrudes in the filling liquid buffer unit in extruder front-axle beam exit.
To achieve the goals above, the technical solution adopted by the present invention is that:
A kind of metal hydrostatic extruder extruded product buffer unit, including it is connected to metal hydrostatic extruder front-axle beam exit
The buffering material-receiving device 5 of setting, buffering 5 end of material-receiving device are provided with buffer unit hydraulic system 1, buffer unit hydraulic system
1 end is connected with discharging platform 4.
The buffering material-receiving device 5 passes through front-axle beam outlet and is connected with die holder.
It is provided with protective cover 3 and protective plate 2 on the outside of the buffering material-receiving device 5 and buffer unit hydraulic system 1, it is described
Protective cover 3 be steel plate protective cover.
5 end of buffering material-receiving device is provided with thick steel plate.
The buffer unit hydraulic system 1 provides oil sources to cushion dashpot 11 by direction valve 1 for oil pump 9, by opening
Opening 2 10 pairs of cushion dashpot tapping of direction valve, pressure valve 1 adjusts the pressure of cushion dashpot, 26 control oil pump outlet pressure of pressure valve,
And open Unloading Effect.
Beneficial effects of the present invention:
A set of filling liquid buffer unit is being arranged in metal hydrostatic extruder front-axle beam exit in the present invention, squeezes in hydrostatic superplasticity
After compressive strain starts, extruded product enters buffering material-receiving device 5, and buffering fluid pressure in material-receiving device 5 later increases to setting
Value, fluid pressure and extruding cylinder pressure are proportional；The product of extrusion is expressed to completely in buffering material-receiving device 5.
The extruded product arranged at beam aperture before metal hydrostatic extruder squeezes out buffering material-receiving device 5, can be by hydrostatic extrusion
The extruded product of superplasticforming is fully wrapped around, and one layer of steel plate protective cover 3 of arranging again outside buffering material-receiving device 5 completely may be used
To play the role of safeguard protection.It also arranges thick steel plate in the end of buffering material-receiving device 5, the pressure at the end of hydrostatic extrusion sometimes
Impact can go out extruded product, this thick steel plate plays end protective effect.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Fig. 2 is buffer unit schematic diagram.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, being provided with filling liquid buffer unit, the filling liquid buffering in metal hydrostatic extruder front-axle beam exit
Device includes buffering material-receiving device 5 and buffer unit hydraulic system 1, via the extruding of super super-pressure hydrostatic extrusion superplastic deformation
Product directly extrudes in the filling liquid buffer unit in extruder front-axle beam exit；Filling liquid buffer unit is that extruded product entrance is filled
Liquid buffer unit, fluid pressure increases to setting value in filling liquid buffer unit later；Its internal liquid pressure in extrusion process
Power and extruding cylinder pressure are proportional；It is that the product squeezed out is expressed to completely in filling liquid buffer unit；Outside buffer unit again
It arranges one layer of steel plate protective cover, safeguard protection can be played the role of completely；It also arranges thick steel plate in the end of buffer unit, hydrostatic
Compression shock at the end of extruding sometimes can go out extruded product, this thick steel plate plays end protective effect.
As shown in Figure 2；The buffer unit hydraulic system 1 provides oil to cushion dashpot 11 by direction valve 1 for oil pump 9
Source, by the 2 10 pairs of cushion dashpot tapping of opening direction valve, pressure valve 1 adjusts the pressure of cushion dashpot, 26 control oil pump of pressure valve
Outlet pressure, and open Unloading Effect.
The working principle of the invention:
Buffering material-receiving device 5 passes through front-axle beam outlet and is connected with die holder, and buffer unit hydraulic system 1 is furnished with direction valve, pressure
The Hydraulic Elements such as valve and cushion dashpot provide buffer medium oil sources for buffer unit and are furnished with pressure monitoring device.Hydrostatic extruder work
When making, product is expressed into buffering material-receiving device 5.When the extrusion force of extruder increases, the pressure medium of buffer unit passes through
Buffer protection work is played in the proportional raising of buffer unit hydraulic system when fortuitous event product is ejected into buffer unit in this way
With, while when protective cover 3 and protective plate 2 also surprisingly pop up for product, provides security protection.There is discharge port in the end of buffer unit,
Product opens discharge port after having squeezed, and takes out on product to discharging platform 4.
