Abstract
The utility model discloses a high-pressure pressurizing and forging device for an upper mold of a novel melt forging machine. The high-pressure pressurizing and forging device comprises an upper large oil cylinder, an upper pressurizing oil cylinder and an upper check valve, wherein the output end of the upper large oil cylinder is connected with the upper mold, the upper pressurizing oil cylinder is arranged above the upper large oil cylinder, an output shaft of the upper pressurizing oil cylinder can stretch into the upper large oil cylinder, and the upper check valve is communicated with the rear cavity of the upper large oil cylinder for preventing the backflow of hydraulic oil caused when the output shaft of the upper pressurizing oil cylinder stretches into the upper large oil cylinder. The high-pressure pressurized and forging device has the beneficial effects that after aluminum alloy melt is filled into the mold, the output shaft of the upper pressurizing oil cylinder stretches into the closed upper large oil cylinder, so that the interior of the upper large oil cylinder generates high pressure which cannot be reached by adopting an oil pump, and the pressure quickly rises, accordingly, forged pieces in the mold are subjected to high-pressure forging, and the forging quality is greatly improved.
Description
Technical field
The utility model relates to a kind of molten soup forging machine, especially relates to a kind of upper die high pressure pressurization forging apparatus of novel molten soup forging machine.
Background technology
The aluminium alloy wheel hub that is used for automobile now mainly is to be produced by gravitational casting, low pressure casting mode, and some is to produce with molten soup forging mode, but used aluminum alloy material all is Al-Si(casting material A356).Some high-end wheel hub is after the heating of Al6061 bar, produces with traditional forging mode.Utilizing gravitational casting mode and low pressure casting mode is to produce the high-strength aluminum alloy wheel hub, the tradition forging mode of using Al6061 bar heating back to forge is the shortcoming that has the apperance of the high shortcoming of equipment investment auxiliary device investment huge and that need and wheel hub not produce accurately, it is directly to produce that spoke has the wheel hub of style, but utilize the Cutter Body Processing with Machining Center style after forging blank, thereby cause the production cost height.One of them technical barrier of molten soup forging machine is,
The utility model content
Technical problem to be solved in the utility model is: the upper die high pressure pressurization forging apparatus that a kind of novel molten soup forging machine is provided, after the molten soup of aluminium alloy is filled into mould, the output shaft of top pressurization oil cylinder enters into the large tank inside, top of sealing, large tank inner generation the in top risen rapidly with the inaccessible high pressure of oil pump and pressure, forging is subjected to the high pressure forging in the mould thereby make, and has improved the forging quality greatly.
For solving the problems of the technologies described above, the technical solution of the utility model is: the upper die high pressure pressurization forging apparatus of novel molten soup forging machine, comprise the top large tank, top pressurization oil cylinder and upper one-way valve, described top large tank output connects described upper die, described top pressurization oil cylinder is installed in large tank top, described top, described top pressurization oil cylinder output shaft can extend into large tank inside, top, described upper one-way valve is communicated with the back cavity of described top large tank, prevents from causing hydraulic oil to reflux when described top pressurization oil cylinder output shaft extend into large tank inside, described top.
Adopted technique scheme, the beneficial effects of the utility model are: after the molten soup of aluminium alloy is filled into mould, upper one-way valve is closed when soon solidifying, the inner closed state that forms of top large tank, at this moment the descending motion of top pressurization oil cylinder, make the output shaft of top pressurization oil cylinder enter into the large tank inside, top of sealing, large tank inner generation the in top risen rapidly with the inaccessible high pressure of oil pump and pressure, making in the mould forging be subjected to high pressure forges, make the density of forging, yield strength, the mechanical performance of hot strength and percentage elongation is improved, and has improved the forging quality greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Wherein: 1, top large tank; 2, top pressurization oil cylinder; 3, upper one-way valve; 4, upper die; 5, intermediate body member.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, the upper die high pressure pressurization forging apparatus of novel molten soup forging machine, comprise top large tank 1, top pressurization oil cylinder 2 and upper one-way valve 3, the output of top large tank 1 connects upper die 4, upper die 4 is installed on the intermediate body member 5, top pressurization oil cylinder 2 is installed in top large tank 1 top, the output shaft of top pressurization oil cylinder 2 can extend into top large tank 1 inside, upper one-way valve 3 is communicated with the back cavity of top large tank 1, prevents from causing hydraulic oil to reflux when the output shaft of top pressurization oil cylinder 2 extend into top large tank 1 inside.
After the molten soup of aluminium alloy is filled into mould, upper one-way valve 3 is closed when soon solidifying, the top large tank 1 inner closed state that forms, at this moment 2 descending motions of top pressurization oil cylinder, make the output shaft of top pressurization oil cylinder 2 enter into top large tank 1 inside of sealing, large tank 1 inner generation the in top risen rapidly with the inaccessible high pressure of oil pump and pressure, making in the mould forging be subjected to high pressure forges, the mechanical performance of density, yield strength, hot strength and the percentage elongation of forging is improved, has improved the forging quality greatly.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the present utility model.
