Abstract
The utility model discloses a reinforced seamless plate type wind power tower forging elliptic door frame, and belongs to the technical field of machine manufacturing. The reinforced seamless plate type wind power tower forging elliptic door frame aims at enabling metal fibers of the reinforced seamless plate type wind power tower forging elliptic door frame to be continuous, free of welding seams and structured in forming, improving the mechanical strength such as the deformation resistance allowable stress of the metal fibers, and prolonging the service life of the metal fibers. According to the technical scheme, the reinforced seamless plate type wind power tower forging elliptic door frame comprises an elliptic section a (1) of a rectangular cross section which is formed through overall forging, an elliptic section b (3) of the rectangular cross section, a straight line section c (2) of the rectangular cross section and a straight line section d (4) of the rectangular cross section, the cross section of each elliptic section is equal to the cross section of each straight line section, cross section widths (W) are small, heights (H) are large, the elliptic sections and the straight line sections are in a plate type shape, and the reinforced seamless plate type wind power tower forging elliptic door frame is simple and suitable in structure.
Description
[technical field]
The utility model belongs to machinery manufacturing technology field.
[background technique]
At present, wind-driven generator is mainly arranged on according to production feature massif spine or the massif bealock place that air quantity is many, wind-force is large, the structural feature of its wind-driven generator includes the steel structure tower body stack shell of a thin and tall cone shape, in its tower body stack shell, is settling multiple electrical installations.The steel structure tower body stack shell of described thin and tall cone shape is due to work under bad environment, constantly bearing powerful inhomogeneous wind-force, its steel structure tower body stack shell bearing load is larger, very easily distortion, careless a little, often make to be arranged on the rectangle doorframe deformation of member on steel structure tower body stack shell, cause the single leaf door being placed on this rectangle doorframe component can not open or closure, have a strong impact on the current of operator on duty or the maintenance of electric equipment is controlled.The described rectangle doorframe component being arranged on steel structure tower body stack shell also has its deficiency, and its deficiency is: mechanical strength is low, yielding, fragile.
Current manufacture and the design of wind-powered electricity generation doorframe, adopt round as a ball welding technique manufacture and steel plate integral cutting figuration manufacture substantially, and the first, there is welding, easily in welding part, lost efficacy, it is large that security risk becomes; The second, there is heat affected zone, for the little thickness of width, large being difficult to is shaped, bad high with reject rate; The 3rd, cutting damage the steel fiber of steel, the reliability of doorframe reduces, the 4th, manufacture steel plate used and require flaw detection and mechanical property to meet associated materials standard-required, for highly large doorframe, steel plate manufacture difficulty is large, cost is high.
[summary of the invention]
Task of the present utility model is to provide a kind of reinforced seamless board-like wind-power tower and forges oval doorframe.Make the steel fiber of its this flange type oval head doorframe component continuous, by suitable heat treatment process, improve the mechanical strengths such as its resistance to deformation allowable stress, by rough forging being carried out to machining, obtain final drawing requirement size, eliminate heat affecting, improve reliability, extend its working life.And simple in structure.
The technical solution of the utility model is as follows:
Seamless board-like wind-power tower forges an oval doorframe, includes the oval section a1 of rectangular cross-section, the oval section b3 of rectangular cross-section and the straightway c2 of rectangular cross-section, and the straightway d4 of rectangular cross-section, its feature is:
Whole doorframe is to drop into by raw material, after heats forged base, by roll over loop technique realize product without parting feature, the described oval section a1 of product, oval section b3 and straightway c2, d4 are one, are all rounding ofves;
The cross section of described oval section a1, b3 and straightway c2, d4 is rectangular cross-section, and profile shows as board-like, and the ratio of width W and height H is more than or equal to more than 1.5, and width w is less than or equal to 100mm simultaneously;
The cross section of described oval section a1, b3 and straightway c2, d4 is to be all equal to cross section completely;
And oval section a1, b3 and straightway c2, d4 have surrounded the door opening of upper and lower two oval spaces and intermediate rectangular spatial composing, size and design meet human body and enter and the moving up of instrument.
The reinforced seamless board-like wind-power tower of the utility model forges oval doorframe, with forging the explained hereafter of rolling over ring die-forging forming, compare with the rectangle doorframe component that its assembly welding is made, steel fiber between oval section a1, b3 and its component of straightway c2, d4 is continuous, and mechanical strength has obtained large increase, and, component surface does not arrange weld seam, also the residual stress of having avoided welding deformation to exist, while oval section a1, b3 and straightway c2, the area size of d4 cross section is consistent, the allowable stress of this flange type oval head doorframe anti-torsion distortion also obtains larger raising, when becoming consistent, Cross section Design can be the pressure and the pulling force that bear from all directions, and, uniform section is convenient to be forged and die-forging forming, convenient manufacture and processing, greatly improved producibility, be easy to batch production and improved manufacturing efficiency, its reinforced seamless board-like wind-power tower forges oval doorframe can bear larger complexity load, and be also improved working life.
The beneficial effects of the utility model are as follows: owing to using technique scheme, its component surface does not have weld seam, component inside steel fiber is continuous, member top and bottom bearing cross-section strengthen, realize the mechanical strengths such as this member anti-torsion distortion allowable stress and obtained larger raising, and can extend the technique effect in its working life; Its uniform section design has facilitated manufacture, has improved manufacturing efficiency, and the utility model is simple in structure.
