In a be the scroll plate schematic perspective view, b therein be the scroll plate schematic cross-sectional view.As shown in Figure 1,
The scroll plate includes volute vortex lug boss 1 and discoidal vortex end cap 2.
In traditional handicraft, the production process of scroll plate is as follows: being respectively completed the forging of vortex lug boss and vortex end cap first
Processing is made, then welds together the vortex lug boss processed and vortex end cap to obtain scroll plate finished product.Traditional handicraft
It deposits, scroll plate is welded by vortex lug boss and vortex end cap, and the fatigue strength of welding position is low, is easy in use process
Existing crackle is even broken.
With the fast development of shaping dies and moulding process, industry has begun using shaping dies and realizes scroll plate
An extrusion forming.For example, the Chinese invention patent of Patent No. 2011202656356 discloses a kind of counterpressure forming mold
Structure is provided with the cavity plate to match with the shape of scroll plate in the mold, blank is put into cavity plate, punch-pin is then controlled
It is pressed down against the counterpressure forming that blank is able to achieve scroll plate.In order to guarantee the forming accuracy of scroll plate, it is necessary to guarantee base first
The plasticity of material enables blank to be full of each region of cavity plate.
The purpose of the present invention is to propose a kind of processing technology of aluminium alloy scroll plate based on counterpressure forming, by base
Material carries out reasonable counterpressure forming pre-treatment, the plasticity of blank is improved, to ensure that the forming accuracy of scroll plate.
Summary of the invention
In order to achieve the above objectives, the invention proposes a kind of processing technology of aluminium alloy scroll plate, its technical solution is as follows:
A kind of processing technology of aluminium alloy scroll plate, it is characterised in that: comprising:
Blanking: the blank of lower predetermined length is sawed from rodlike aluminium alloy stock；
Pre-add heat treatment: blank being sent to heating furnace and is heated to 200~250 DEG C, takes out blank and the surface in blank
It is small to keep the temperature 2 for one layer of graphitic lubricant of uniform fold after then being sent again by blank into heating furnace and being heated to 480~550 DEG C
When, it finally takes out blank and forges lubricant in one layer of aluminium of blank surface uniform fold；
Forging and molding: blank is put into squeezing in the cavity plate of counterpressure forming mold and to blank, is vortexed with realizing
The forging and molding of disk；
Fixation rates: the scroll plate first product after forging and molding is fed directly to be sequentially completed in solid solution aging furnace solid
Molten, ageing treatment, in which: solid solubility temperature is set as 560 DEG C, keeps the temperature 1.5h, and aging temp is set as 180~200 DEG C, heat preservation
6h。
In a specific embodiment, after the blanking step, before pre-add heat treatment further include:
Impeller blasting: carrying out impeller blasting using surface of the shot-blast cleaning machine to blank, to remove its surface spikes, improve
Its surface roughness.
In a specific embodiment, heating furnace employed in the pre-add heat treatment is box pre-add hot stove.
Compared with the processing technology of aluminium alloy scroll plate in the prior art, the present invention is by reasonably carrying on the back blank
Pressing formation pre-treatment, has been obviously improved the plasticity of blank, to ensure that the forming accuracy of scroll plate.
Detailed description of the invention
In order to illustrate the technical solution of the embodiments of the present invention more clearly, needing to make described in below embodiment being described
Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only some embodiments of the present invention, for this
For the those of ordinary skill of field, without creative efforts, it can also be obtained according to these attached drawings others
Attached drawing.Wherein:
Fig. 1 is a kind of structure chart of scroll plate；
Fig. 2 is the product form variation diagram in the processing technology of aluminium alloy scroll plate provided by the invention.
Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
Referring to FIG. 2, in a specific embodiment, the processing technology of aluminium alloy scroll plate provided by the invention includes such as
Lower step:
1, blanking: the blank of lower predetermined length is sawed from rodlike aluminium alloy stock, to obtain rodlike blank 2a.
2, impeller blasting: impeller blasting is carried out using surface of the shot-blast cleaning machine to rodlike blank 2a, to remove its surface
Burr improves its surface roughness, obtains the rodlike blank 2b with high-quality surface.
3, pre-add is heat-treated: rodlike blank being sent to box pre-add hot stove and is heated to 200~250 DEG C, takes out rodlike base
Expect and in one layer of graphitic lubricant of the surface uniform fold of blank, then rodlike blank is sent again into box pre-add hot stove simultaneously
2 hours are kept the temperature after being heated to 480~550 DEG C, finally take out rodlike blank and forges lubricant in one layer of aluminium of its surface uniform fold,
Obtain preheating treated rodlike blank 2c.
Material plasticity (or mobility) by preheating treated rodlike blank 2c is significantly improved, and outside it
The aluminium forging lubricant on surface then can form effective protection to counterpressure forming mold.
4, forging and molding: rodlike blank 2c is put into squeezing in the cavity plate of counterpressure forming mold and to rodlike blank 2c
Pressure, to obtain the scroll plate first product 2d of forging and molding.
It should be noted that the specific structure and extrusion principle of counterpressure forming mold are ripe for persons skilled in the art
Know, also and the protection point of non-present invention, therefore this specification is no longer described in greater detail.Those skilled in the art are in reality
When applying the present invention, various types of counterpressure forming molds in the prior art, such as background skill can be selected according to specific needs
Counterpressure forming mold knot disclosed in the Chinese invention patent of Patent No. 2011202656356 mentioned by art content part
Structure.
5, fixation rates: the scroll plate first product 2d after forging and molding is fed directly in solid solution aging furnace, the institute
It states and is formed with solid solution region and timeliness region in solid solution aging furnace, scroll plate first product is successively complete in solid solution region and timeliness region
At solution treatment, ageing treatment, in which: the temperature setting for being dissolved region is 560 DEG C, and scroll plate first product is kept the temperature in the region
1.5h；The temperature setting in timeliness region is 180~200 DEG C, and scroll plate first product keeps the temperature 6h in region.
After fixation rates, scroll plate finished product 2e is obtained.The scroll plate after fixation rates at
Product 2e has many advantages, such as hardness scattered error is small, deformation is small, high mechanical strength.
Further, since the scroll plate first product 2d after forging and molding is sent directly into when being dissolved in solid solution aging furnace
Effect processing, therefore scroll plate first product 2d carry residual forging heat be utilized, thus reduce the power consumption of solid solution aging furnace,
Resource is saved.
The description with certain particularity detailed enough has been carried out to the present invention above.Ordinary skill in fields
Personnel are it should be understood that the description in embodiment is only exemplary, before without departing from true spirit and scope of the present invention
Put make it is all change all should belong to protection scope of the present invention.Scope of the present invention is by the power
What sharp claim was defined, rather than limited by the foregoing description in embodiment.
