Definitions
- the invention relates to a method for reshaping structural components, in particular those for use in aerospace, the structural components having a plate-shaped base body and elongated and approximately parallel ribs extending approximately at right angles therefrom and integrally connected to the base body, the Reshaping is carried out by particles of an abrasive, which strike surface areas of the structural component at high speed and cause plastic material deformation.
- Forming processes of the type described in the introduction have long been used in the aerospace industry for the curvature of large-area components, for example of wings or fuselage shells.
- Abrasives with a particle diameter of up to 2 - 4 mm are mainly used for forming structural components. While the abrasive is used for large-area processing of the components with the help of centrifugal wheels, hand blasting systems are used for the localized forming. These hand blasting machines are also used to bend ribs. In order to be able to deliberately deform the usually flat ribs on the basis of the beam geometry and the beam diameter, the ribs to be machined are partially covered with a mask, so that the desired expansion gradient is achieved in the rib regions to be reshaped.
- Rubber or another shock-absorbing material is used to cover the non-pressurized surface sections of the ribs. Covering the ribs requires a great deal of effort, especially if several masks have to be made.
- the so-called tong process (Eckhold process) is known from the prior art.
- pliers with a kind of clamp grip grips the rib with two spaced gripping jaws at two adjacent locations. By a short movement of the two gripping jaws away from or towards each other, the rib is either locally stretched or compressed. Continuous convex or concave curvatures can be created by repeated use along the length of the rib. The curvature can be affected by the pincer stroke and the number of repetitions of these applications.
- So-called age creep forming processes for structural components are also generally known.
- the component is first produced in a flat shape by machining, in particular by milling.
- the component is then placed in a mold that has the outer contours of the finished component.
- the component is adapted to the shape under the influence of pressure and temperature. This process usually takes several hours.
- Another disadvantage is that special shapes have to be made for each geometry. It is also necessary to determine the parameters, temperature, pressure and time for each component separately.
- the use of the creep forming process is ruled out for materials that are not suitable for the heat treatment carried out. Another difficulty is to overstretch the component in the mold to a certain extent in order to compensate for the springback after the component has been removed from the mold, so that the exact desired component geometry is present.
- the prior art also includes the process known from US Pat. No. 4,329,862 for the shot peening of plate-shaped components, in particular of wing structures.
- the wing components to be blasted are reinforced by ribs.
- the aforementioned US patent teaches to stretch the component in a first step by applying blasting agent on both sides and then to bend it in another direction by applying blasting agent on one side only.
- one of the methods used in practice for reshaping structural components is to mill them from solid material using modern CNC milling machines. Apart from the considerable expenditure of material, this is only possible with slightly curved structures. The cost of the raw material to be made available in large thickness is considerable. Therefore, this method - especially for large components - can only be used economically in very few cases.
- machining results in strong springback effects in the finished component, which impair its dimensional accuracy.
- the invention is based on the object of proposing a method for reshaping structural components with which the most varied of geometries can be implemented on the finished components in a reliable and cost-effective manner.
- this object is achieved according to the invention in that particles of the blasting agent are simultaneously applied to opposing surface regions of the ribs on opposite longitudinal sides.
- the strength of the radius of curvature is influenced by the size and speed of the particles of the blasting medium and the duration of the blasting treatment.
- Base body can be dispensed with. Automation of the proposed method is also possible, in particular if the geometry of the structural component being treated is measured online and is included in a control strategy for controlling the method.
- either a longitudinal strip of the rib adjacent to a rib base or a longitudinal strip of the rib adjacent to a rib head can be exposed to particles of the abrasive, wherein the width of the longitudinal strips can correspond at most to the height of the ribs.
- the longitudinal and / or transverse ribs of the component in the foot area are lengthened by the blasting agent application. This results in a concave curvature of the component, the term concave referring to the side of the plate-shaped base body provided with the ribs.
- a convex curvature of the component is caused by an extension of the longitudinal and / or transverse ribs in the head region, i.e. H. in the vicinity of their longitudinal end face.
- both single-axis and multi-axis component curvatures and developments can be created.
- the longitudinal ribs in the foot area are lengthened, whereas the transverse ribs in the head area are lengthened, a combination of concave and convex curvature of the component results, which creates a saddle-shaped geometry.
- a saddle-shaped structure can be achieved in that a curvature transverse to the longitudinal direction of the ribs is carried out by blasting agent treatment of the base body in the (one-sided) manner known from the prior art.
- the particles of the blasting agent have an average diameter of more than 4 mm. This means that structural components with thick-walled ribs can also be reliably formed. Large particles, in particular large balls with a diameter of more than 4 mm, allow the rib to penetrate to a great depth.
- a further development of the method according to the invention consists in that the particles of the blasting agent emerge from opposing, directed nozzles of a blasting device which is moved in the longitudinal direction and in the vertical direction of the ribs.
- This enables automation in the implementation of the method and the implementation of a wide variety of geometries.
- it is advantageous to move the nozzles synchronously in the same direction and at the same speed. This ensures that opposing surface areas of the rib are always acted upon even when the treatment site is continuously shifted.
- a device for reshaping structural components in particular for
- the structural components having a plate-shaped base body and elongated ribs extending at right angles from it, integrally connected to the base body and extending approximately parallel to one another, enables particles of an abrasive impinging at high speed to be applied to surface areas of the structural component, making a plastic
- Material deformation is effected, and according to the invention is characterized by at least two nozzles for a directed exit of one particle beam each, the two particle beams being directed towards one another and the nozzles being at a greater distance from one another than the thickness of the rib.
- the nozzles can preferably be placed in spaces between adjacent ribs, which makes it possible to direct the particle beams onto the rib surface at an angle of approximately 90 °.
- the previously described forming process can be carried out with comparatively simple means.
- the fixed assignment of the two nozzles or the exit directions of the particle jets to one another always ensures that opposing surface regions of the rib are acted upon. If the nozzles can be placed in spaces between adjacent ribs, a perpendicular direction of impact of the particles on the surface areas to be processed is possible.
- the nozzles can be moved together in the longitudinal direction and in the vertical direction of the ribs, as a result of which reshaping can also be carried out at large parts of the ribs in the case of large components.
- a large number of possible geometrical reshapings can thus be implemented on the component to be reshaped.
- 1 shows a device for shaping a structural component with two nozzles directed towards one another;
- 2a shows a perspective view of a section of a structural component;
- FIG. 2b shows a side view of the component according to FIG. 2a
- Fig. 5 as Figure 4, but with concave curvature.
- FIG. 1 shows only two nozzles la and lb of a device for reshaping structural components, from the front 2 a and 2 b of which a slightly conically expanding jet 3a / 3b of a particulate blasting agent emerges.
- the particles of the abrasive have a spherical shape and have a diameter of more than 4 mm (for example 6 mm).
- the supply of the blasting agent to the nozzles 1 a and 1 b and the other components of the blasting device are generally known and are therefore not shown in detail.
- a structural component 4 is formed from a metallic material using the partially illustrated forming device.
- This structural component 4 consists of a plate-shaped base body 5, which is only shown in sections, and a plurality of ribs 6, which extend at right angles therefrom and are integrally connected to the base body 5, of which only a single section is shown for the sake of clarity.
- the ribs 6 run parallel and equidistantly at a distance from one another such that the nozzles 1 a and 1 b, including the associated feed device, can be positioned in the spaces between adjacent ribs 6.
- FIG. 1 shows the case with nozzles 1a / 1b oriented perpendicular to the rib 6.
- the particle beams it is also possible for the particle beams to strike the fin surface obliquely from above at an angle deviating from 90 °.
- the nozzles la / lb can then be arranged and moved in a plane above the top of the ribs.
- the common longitudinal axis 7 of both nozzles la / lb runs perpendicular to the two side surfaces 8a and 8b of the rib 6. This ensures that opposite and essentially congruent surface areas are acted upon by the jets 3a and 3b on the opposite side surfaces 8a and 8b , If the abrasive intensity is the same, there is a force equilibrium in the area of the applied rib sections, which prevents the rib 6 from bending or being deflected on one side.
- FIGS. 2a and 2b show a structural component 4, shown in detail and in perspective in a side view, in which a longitudinal strip 10 starting from a rib head 9 and running parallel to the longitudinal extension of the rib 6 is particularly emphasized.
- This longitudinal strip 10, the width 11 of which makes up approximately 40% of the height 12 of the rib 6, is acted on with blasting agent with the aid of the nozzle 2b.
- an opposite longitudinal strip 10b (not visible in the figures) with the same width 11 is also exposed to blasting agent, with the aid of the nozzle 2a.
- the nozzle arrangement shown in FIG. 1 is therefore overall, i. H. without the two nozzles 2a / 2b changing their position and orientation relative to one another, can be moved in the longitudinal direction of the rib 6 - for example at a constant speed.
- FIG. 2 c shows the shape of the structural component 4 after blasting agent treatment in the area of the longitudinal strips 10a and 10b. Due to the material expansion occurring in the area of the rib head 9, i. H. an extension of the component in this area, both the rib 6 and the integrally connected base body 5 assume a convexly curved shape. Despite the curved shape, the side surfaces 8a and 8b of the rib 6 lie within one plane.
- the structural component 4 can also be given a curvature perpendicular to the longitudinal extension of the ribs 6 by blasting treatment of either the underside 13 or the top 14 of the base body 5.
- a curvature perpendicular to the longitudinal extension of the ribs 6 by blasting treatment of either the underside 13 or the top 14 of the base body 5.
- saddle-shaped structures can be created.
- structural components with a cassette structure, ie ribs crossing each other in the longitudinal and transverse directions of the component such a saddle-shaped structure can be achieved solely by blasting the ribs.
- an additional blasting treatment of the base body is optionally also possible here.
- FIGS. 3a to 3c show the case in which a concave curvature of the structural component 4 is to be produced with the aid of an abrasive treatment.
- the longitudinal strip 10a ' is located in the region of the rib base 15 and adjoins the top 14 of the base body 5 directly.
- the structural component 4 assumes the concavely curved shape shown in FIG. 3c. Due to the stretching of the rib 6 in its foot region, the material of the plate-shaped base body 5 is also stretched at the same time. The width 11 of the longitudinal strips 10a 'and 10b' is again approximately 40% of the height 12 of the structural component 4.
- FIGS. 4 and 5 finally show the expansion distribution in the region of the longitudinal strips 10a (on the fin head) or 10a '(on the fin foot) to be blasted with blasting media. While the elongation in the case shown in FIG. 4 increases linearly from zero to a maximum value starting from a lower boundary line 16 of the edge strip 10a up to the rib head 9, the elongation in the structural component 4 according to FIG. 5 likewise increases linearly starting from an upper boundary line 17 of the longitudinal edge strip 10a 'up to the rib base 15 at the transition into the base body 5, where a maximum value of the stretch is present.
