Abstract
The utility model relates to the processing technical field of nonferrous materials and provides an arc-shaped magnesium alloy blank plate used for producing a wide magnesium alloy plate strip, wherein the cross section of the arc-shaped magnesium alloy blank plate (3) is in a W shape consists of three arcs; the radian measures of the three arcs of the arc-shaped magnesium alloy blank plate (3) are same; the two sides of the arc-shaped magnesium alloy blank plate (3) are symmetrical structures along a central line in a length direction; the length of the arc-shaped magnesium alloy blank plate (3) is 600mm; the straight line width of the arc-shaped magnesium alloy blank plate (3) is 320mm; and the unfolding width of the arc-shaped magnesium alloy blank plate (3) is 620mm. The arc-shaped magnesium alloy blank plate is used as a blank plate for producing the wide magnesium alloy plate strip; the curved surface of the arc-shaped magnesium alloy blank plate is flattened through a flattening process at a later period, so that the purpose of increasing the width is achieved and the wide magnesium alloy blank plate strip with width of 620mm is produced by utilizing a small-sized extruder, a supporting mould and a flattening device.
Description
Technical field
The utility model includes non-ferrous metal materials processing technology field, relates in particular to a kind of arc magnesium alloy blanket that is used for production wide cut magnesium alloy board.
Background technique
Magnesium is one of element the richest on the earth, in present practical applications, is the metallic material that quality (1.74g/cm3) is the lightest, specific strength is the highest, compares with the lightweight engineered plastics, and magnesium alloy has higher elasticity and plastic deformation ability; (2.8g/cm3) compares with aluminum alloy, and magnesium alloy is not only light, and anti-vibration and noise reduction sound ability height, and has very strong decay resistance, capability of electromagnetic shielding, shielding property, recovery utilization rate advantages of higher.Therefore; Be the most desirable, the most practical lightweight structural material in pillar industries such as communications and transportation (automobile), Aero-Space, relief printing, electronics (3C Product) and household electric appliance, be called as the green engineering material of tool development and application potentiality " 21 century ".
The magnesium alloy application form mainly contains cast magnesium alloy and wrought magnesium alloy.Wrought magnesium alloy is through pressure rolling, extruding; Have advantages such as grain refinement, intensity is high, the extension performance is good; Wherein magnesium alloy sheet is expected extensive use in fields such as machine-building, Aero-Space, automobile, electronics, instrument, chemical industry and digital product; Added value of product and economic benefit are higher, have bright prospects.Carry out research and the application with high-performance magnesium-alloy of automobile, motorcycle the earliest in North America, Europe; The demand of magnesium alloy die casting and deformed magnesium alloy material increases with the amplification of annual mean 20% fast in recent years, and Japan has thrown huge fund and carried out 3C Product Mg Alloy and application.
With at present ripe magnesium alloy cast compared with techniques, the development of Technology of Plastic Processing such as the forging of magnesium alloy, extruding, rolling, punching press and superplastic forming technology is then relatively slow.
Two kinds of technologies of the general employing of current domestic and international production magnesium alloy sheet:
1, finish rolling again after the casting cogging: casting-milling technology parameter control difficulty, degree of normality is lower, and technical difficulty is higher.Should not realize that package produces continuously.
2, finish rolling again behind the extrusion blooming, advantage are that good, the easy realization of material structure performance is produced continuously, the rolling supply of material, shortcoming be disposablely have high input, template control difficulty.The restriction of machine outlet size and extruding force owing to be squeezed, the general maximum of 2500t extrusion press cogging width can only reach about 300, and large-tonnage extrusion press cost is very expensive.The extrusion equipment of little tonnage can only be used to produce 320mm magnesium alloy plate in a narrow margin, but the high-performance magnesium-alloy plate of wide cut is badly in need of in market again, is applicable to fields such as machine-building, Aero-Space, automobile, electronics, instrument, chemical industry and digital product.
Summary of the invention
For overcoming the deficiency of existing technology, the purpose of the utility model provides a kind of arc magnesium alloy blanket that is used for production wide cut magnesium alloy board.
For realizing the foregoing invention purpose, the utility model adopts following technological scheme:
A kind of arc magnesium alloy blanket that is used for production wide cut magnesium alloy board; The cross section of described arc magnesium alloy blanket is the W shape of being made up of three arcs; The radian of three arcs of said arc magnesium alloy blanket is identical, and said arc magnesium alloy blanket center line both sides along its length is a symplex structure; Said arc magnesium alloy blanket length is 600mm, arc magnesium alloy blanket linear width 320mm, and the spreading width of arc magnesium alloy blanket is 620mm.
Owing to adopt aforesaid technological scheme, the utlity model has following superiority:
A kind of arc magnesium alloy blanket that is used for production wide cut magnesium alloy board; It is as the blanket of production wide cut magnesium alloy board; The camber line that utilizes point-to-point transmission is forever than the principle of length, and the later stage flattens through the curved surface of flattening process to arc magnesium alloy blanket, reaches the purpose that increases fabric width; Realization utilizes small-sized extrusion press, matching die and flattening device fabrication wide cut (width is 620mm) magnesium alloy board.
Description of drawings
Fig. 1 is the W shape arcuate die structural representation that is used to produce arc magnesium alloy blanket.
Fig. 2 is the utility model structural representation.
Among the figure: 1. W shape arcuate die, 2. W shape arc cavity, 3. arc magnesium alloy blanket.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 2; And with reference to Fig. 1; A kind of arc magnesium alloy blanket that is used for production wide cut magnesium alloy board; The cross section of described arc magnesium alloy blanket 3 is the W shape of being made up of three arcs, and the radian of three arcs of arc magnesium alloy blanket 3 is identical, and said arc magnesium alloy blanket center line both sides along its length is a symplex structure.The length of said arc magnesium alloy blanket 3 is 600mm, arc magnesium alloy blanket linear width 320mm, and the spreading width of arc magnesium alloy blanket is 620mm.
Be example with the AZ31 magnesium alloy below
The magnesium alloy cast billet forges the cylindrical rod base that is processed into Ф 240mm through 5 passage multiaxises.The cylindrical rod base of heating is delivered to the extruding of 2500t extrusion press, through W shape arc cavity 2, is squeezed into arc magnesium alloy blanket 3 as shown in Figure 2 through the W shape arcuate die shown in Fig. 11.Arc magnesium alloy blanket length is 6 meters, arc magnesium alloy blanket width rectilineal interval 320mm, and the length that arc magnesium alloy blanket launches camber line is 620mm.It is flat to carry out preview through the first road arc roller flattening machine then, gets into the second road flat pattern roll subsequently, 5 roller flattening machines are launched into magnesium alloy flat board, band.At last, the 3rd road polishing flat roll mill, the rolling reduction with 5% carries out warm-rolling to the magnesium alloy plate after flattening, band, eliminates the extruding slide mark on magnesium plate surface, finally by the crimping machine rolling.
