Abstract
The utility model discloses a wind power forged flange ring piece. A plurality of through holes are uniformly distributed around the circle center on the forged ring, or the forged ring is machined as a gear ring or a bearing ring; and the wind power forged flange ring piece is characterized in that: the maximal outer diameter of the forged ring is 16-18 m. A large-size flange made by machining a large-size forged ring ensures the large-size tower frames to be connected more conveniently, and provides convenience for operation such as installation, disassembly and repair of the large-size tower frames.
Description
Technical field
The utility model relates to wind power generation field, particularly relates to a kind of ring rolling that is used to process the large scale flange that the wind-power electricity generation pylon connects.
Background technique
Flange is a kind of annular element, and is the most common in pipework, and flange all is to use in pairs.In pipework, flange is mainly used in the connection of pipeline.On the pipeline that needs connect, at each end a slice flange plate is installed, low pressure pipeline can use the wire connection flange, 4 kilograms of use welded flanges with upward pressure.Add sealing gasket between two flange plate, use bolton then.The flange of different pressures has different thickness and uses different bolts.Ring rolling is that flange " blank " flange is on the basis of ring rolling, to process.
The wind-powered electricity generation industry development is very fast at present, and the pylon general diameter that is used to connect in the wind-powered electricity generation is bigger, and general diameter reaches several meters; Even more than 10 meters, and present flange general size is less, general flange outer diameter is no more than 2 meters; The pylon that is not suitable for the wind-powered electricity generation industry connects, and if these pylons adopt and are welded to connect, all inconvenient for installation, transportation, dismounting, maintenance etc.; Therefore, be necessary to design a kind of large scale flange.In addition, other field, for example space industry, aviation field also need some larger-size rings.Therefore, be necessary to design a kind of large-sized ring rolling.
The model utility content
The purpose of the utility model is to overcome the defective that exists in the existing technology, and a kind of ring rolling that is used for machining large-sized flange is provided, particularly a kind of ring rolling that is applicable to the large scale flange of the pylon connection of processing wind power generation field.
For realizing above-mentioned purpose, the technological scheme of the utility model is a kind of wind power flange ring rolling spare of design, on said ring rolling, is evenly equipped with several through holes around the center of circle, or is processed into gear ring or race ring, it is characterized in that the maximum outside diameter of ring rolling is of a size of 16～18m.
Optimized technical scheme is that said wind power flange ring rolling spare is processed by steel.
Further optimized technical scheme can be that said steel are Q295A or B level steel.
Further optimized technical scheme can also be that said steel are Q345A, B, C, D or E level steel.
Further optimized technical scheme can also be that said steel are Q390A, B, C, D or E level steel.
Further optimized technical scheme can also be that said steel are Q420A, B, C, D or E level steel.
Further optimized technical scheme can also be that said steel are Q460C, D or E level steel; Perhaps said steel are alloy structure steel or bearing steel.
Optimized technical scheme comprises that also said wind power flange ring rolling spare processes through forging.
Optimized technical scheme comprises that also said wind power flange ring rolling spare is welded by uniform several portions.
The advantage of the utility model is with beneficial effect: it is convenient that the large scale flange that processes with the large scale ring rolling is connected larger-size pylon, is convenient to the operations such as installation, dismounting, maintenance of the big pylon of size.
Description of drawings
Fig. 1 is the structural representation of the utility model wind power flange ring rolling spare;
Fig. 2 is the structural representation that the utility model wind power flange ring rolling spare connects together.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technological scheme of the utility model, and can not limit the protection domain of the utility model with this.
Like Fig. 1, shown in Figure 2, the wind power flange ring rolling spare of present embodiment is evenly equipped with several through holes around the center of circle and is processed by metal, or ring rolling is processed into gear ring or race ring on ring rolling spare.The material of processing ring rolling adopts steel material usually, preferably adopts Q295A, B level, or Q345A, B, C, D, E level; Or Q390A, B, C, D, E level; Or Q420A, B, C, D, E level, or Q460C, D, E level steel, perhaps steel also can be Alloy Constructional Steel material or bearing steel.Wind power flange ring rolling spare can adopt the processing mode of forging, also can a part ring rolling be merotomized uniformly, welds together then.The maximum outside diameter size of ring rolling spare is generally 16～18m.The pylon that the flange that is processed by the wind power flange ring rolling spare of present embodiment is mainly used in the wind-power electricity generation connects, and also can be used for the large scale ring in other field, fields such as for example space flight, aviation, military project, machinery.
Can find out that by above embodiment it is convenient that the easy machining large-sized flange of the utility model embodiment's wind power flange ring rolling spare, large scale flange connect larger-size pylon, be convenient to the operations such as installation, dismounting, maintenance of the big pylon of size.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
