Description

Half-finished manufacture method of wing-shaped element
Technical field
The present invention relates to the half-finished manufacture method of wing-shaped element and the manufacture method of wing-shaped element itself.This wing-shaped element forms with various form.The so-called blade that is fixed on the aircraft wing wing flap is mentioned as an example.
Background technology
The various manufacture methods of this wing-shaped element have been behaved known.At first to mention extruding of element.In this case, element needn't be made of separated portions, quick like this and relative less expensive.But its defective is that dimensional tolerance is very poor.Especially under the situation of less relatively thickness, this defective can occur.According to another kind of known method, element is by the sheet material manufacturing.After the preform sheet material, sheet material stretches on the stretching straightener, is used to form the parts (section bar) with bottom and top.Axle is included in the preformed sheet material.The integral body of Xing Chenging is clipped in longitudinal end and stretches then thus.Its defective of this known method is that the surface that is obtained has scrambling.
Summary of the invention
The purpose of this invention is to provide a kind of process of semi-finished that is used to make wing-shaped element, it does not have these defectives.Described purpose reaches by a kind of half-finished manufacture method of wing-shaped element, wherein these semi-finished product have the arc diapire and the arc roof of leading edge, back edge and extension spaced from each other between leading edge and back edge in cross section, and this method comprises the steps:
-metal sheet is provided,
-bent sheet, forming the curved region of two panels and panel institute adjacency,
-the shape that provides former, its outside to have the inner surface of the parts (section bar) after finishing,
-former is placed in the bent sheet, make the leading edge of former be positioned at curved region,
-edging machine that is provided with opposed pressing piece and rubber blanket is provided,
-former is fixed on the pressing piece,
-promote pressing piece to rubber blanket, wherein bent sheet is enclosed between them, and makes described sheet material distortion between former and rubber blanket,
-take off the former that has the shaping sheet material from edging machine,
-they are placed in the rubber press that is provided with bottom biock, this bottom biock has its shape and is similar to corresponding cavity at least with the outer shape of a wall of shaping sheet material,
-extrusion molding sheet material, wherein former between bottom biock and rubber mat plate,
-take off semi-finished product from rubber press.
Adopt the method according to this invention, semi-finished product are shaped by being exerted pressure thereon by rubber element.In conjunction with the former that is used as axle and has suitable profile, can obtain shape very accurately by this method, this shape has the surface of aircraft because of the required smoothness of aerodynamics reason.
Preferably, after bent sheet or before or two panel-shaped cambers meanwhile.In order to obtain firm relatively curved element, arc can be towards same direction.But, arc also can be toward each other back to direction.
Curved panel and as selecting to make the panel embowment can be by rolling forming or by rolling realization.The back edge of element can form the parts (section bar) that are fixed on roof and the diapire.In addition, wing-shaped element can be accepted heat treatment, for example stress relief annealing or solution annealing.
The invention still further relates to the wing-shaped element of making according to this method, according to said method, this element for example can form blade.
Please refer to disclosed wing-shaped element among the US-A 4531270.This element is made by flat relatively parts (section bar), and wherein these parts comprise two panels that form an integral body, and wherein finally the arc of wall with the bigger material thickness preproduction in part.This element is by folding panel mutually simply and acquisition thus, and element manufacturing is after this finished.Here the element that relates to is the form of turbine blade.
Description of drawings
Exemplary embodiment below with reference to the accompanying drawings illustrates in greater detail the present invention.
Fig. 1 has shown curved and the arc sheet material, and this sheet material is as the raw material of the method according to this invention.
Fig. 2 has shown the element in the edging machine.
Fig. 3 has shown the effect after handling in edging machine.
Fig. 4 has shown the perspective view of the rubber press of the rubber press that has axle.
Fig. 5 has shown the product that obtains after the rubber compacting.
Fig. 6 has shown the wing-shaped element after finishing.
The specific embodiment
When implementing the method according to this invention, employed raw material are the bent sheet 1 shown in Fig. 1, and it has carried out bending, make to form crooked leading edge 2, depression curved panel 3 and protrude curved panel 4.This bent sheet 1 is placed in the edging machine 5 shown in Fig. 2, and this edging machine has base 6 and the pressing piece 8 that has rubber blanket 7, and wherein pressing piece can move up and down and former 10 is fixed thereon by support 9.This former 10 or axle 10 also are shown among Fig. 4 with perspective view.It has the shape of the inner surface of the wing-shaped element after finishing, and that is to say, has the end face and the bottom surface of leading edge, back edge and arc.This former can be prismatic and twisted shape.
When extruding bent sheet 1 in edging machine, the leading edge of former 10 is pushed in the curved region 2 of sheet material 1.In this way, under the even inside pressure effect of rubber blanket 7, this curved region is further crooked around the leading edge of former 10.As a result, curved panel 3 and 4 is more approaching mutually, as shown in Figure 3.
The sheet material 1 that further is shaped is placed in the rubber press then by this way, and the rubber press 11 of this forcing press is shown among Fig. 4, and its interior shape is corresponding with the leading edge and the curved surfaces of wing-shaped element.The sheet material 1 that has shape shown in Fig. 3 now is placed in the rubber press 11 with axle 10.Rubber mat plate 12 is placed in this above integral body then, and after this, the sheet material 1 that wherein has axle 10 is extruded between rubber press 11 and rubber mat plate 12 by the forcing press (not shown).
After the rubber compacting, obtain the semi-finished product 13 shown in Fig. 5, it has curved front edge 2, protrudes arc top surface 4 and depression lower arcuate surface 3.At last, whole parts (section bar) by reference marker 14 expressions are fixed to the free rear end of wall 4,3.Therefore, these parts have body 15, and this body has relative to each other downward-sloping side 16,17, and they are oriented consistent with the bearing of trend of roof 4 and diapire 3.Parts 14 are fixed on the semi-finished product 13 by the rivet 18 that passes roof 4, body 15 and diapire 3, and after this wing-shaped element 15 is made and finished.As selection, wall 4,3 also can, for example directly fixed to one another by bonding, riveted joint etc.
