Definitions
- the invention relates to a method for forming a profile and a profile used according to this method.
- To use a profile is to deform such a profile of way to create a gap between two of its parts.
- the profile to soyer is a beam of any section having in its profile a mast and wings at both ends of it mast.
- the purpose of the invention is to reduce a length in the offset conferred by a soy.
- the present invention finds an application particularly advantageous, but not exclusive, in the field of aeronautics.
- a bent profile is used to strengthen a connection between two pieces, such as two parts of an airplane, that are not aligned one with respect to the other.
- FIG. 1 shows a view of a profile 100 of the state of the technical.
- This profile here has an I-shaped section but could have any section, such as a C or U section.
- profile 100 comprises a first and a second wing 101 and 102 and a mast 103.
- the first wing 101 is of great thickness E1 and the second wing 102 is of small thickness E2.
- This profile 100 is used for providing or reinforcing a connection between a part 121 and a part 122.
- the first wing 101 and the second wing 102 unfurl each in a plane which forms a non-zero angle with a plane of the mast 103, itself located in the plane of Figure 1.
- these wings 101 and 102 each unfurl in a plane that is perpendicular to a mast plane 103.
- a linkage 104 is present between a first part 105 and a second part 106 of the profile. This sorting 104 corresponds at the part of the profile 100 which is deformed. This sorting 104 provides a between the first part 105 and the second part 106.
- the offset extends in the plane of the mast 103 of the profile with a height H of offset measured in a direction perpendicular to the plane of the wings 101 and 102, and with an offset length L measured in one direction parallel to the plans of the mast 103 and wings 101 and 102.
- This length L is calculated according to a thickness of a wing.
- the length L is globally equal to six times the thickness of a wing. This relationship between the thickness of a wing and the length L varies depending on the material in which the profile is made. Length L is as short as possible but can not be reduced as much as desired. Indeed, the proportion of six times the thickness of the wing is a constraint that can not be transgressed without risk of deterioration of the profile.
- the length L is calculated from the thickness of the larger of the two wings. In Figure 1, the length L is therefore equal to six times the thickness E1 of the wing 101 of great thickness. In its trimming 104, the profile 100 therefore has identical slopes on both sides wings 103 and 104
- the used section 100 is used to reinforce a connection between two parts 121 and 122 having a difference in level.
- a space 130 depending on the length L is observable between the pieces 121 and 122 and the 100.
- the space 130 between the parts and the profile is important. AT the place of such a space 130, the profiles soys of the state of the art do not therefore not optimally involved in strengthening the link between rooms 121 and 122.
- the invention aims to solve this problem of space 130 too between the profile 100 and the parts 121 and 122.
- the invention implements, in particular, a profiled section with offset lengths calculated according to each thicknesses of the profile.
- the length of the offset provided by the side of the wing of great thickness is greater than the length of the offset provided by the squelching of the side of the thin wing. In the invention, these lengths are no longer identical.
- the sinking of the seam profile according to the invention comprises a geometry particular in which ends of the carousel forms a quadrilateral looking like a trapeze unlike near slopes. In this quadrilateral, no side is parallel to another. Projections end of the searing on the side of the thin wing are preferably located inside projections of ends of the squelch of the side of the wing of great thickness.
- the thin wing on two pieces non-aligned links between them is to strengthen.
- the length of the offset provided by the squelch of the side of the thin wing is equal to N times the length of the small thickness; whereas this length would have been equal to N times the length of the great thickness using a state of the art trimming method.
- N is in an example equal to six but varies depending on the nature of the material in which the profile is made.
- a method is implemented in which is pressed with a punch on a profile wedged between this punch and an anvil.
- a punch is made which comprises a part with a shallow gradient extending over a length proportional to the thickness of the wing of great thickness.
- an anvil that has a steeply sloping portion length which is proportional to a thickness of the wing of small thickness. The anvil is fixed. The punch is mobile.
- the side of the profile with the thin wing is placed against the anvil.
- the punch is placed against the side of the profile including the large wing thickness.
- the placement of the punch is realized in such a way that projections of ends of the part of the anvil presenting a slope in the opposite direction of a support, are located between projections of ends of the part of the punch having a slope in the direction of support. In particular achievements, some projections may to be confused with each other.
- the punch is then pressed so that the profile is compressed between the punch and the anvil.
- the shapes printed by this punch and this anvil on one side and the other of the profiling of the profile are different.
- the punch comprises a segment of steep slope and the anvil has a low slope segment.
- FIG. 2 shows the profiled section 200 according to the invention comprising as in Figure 1, the mast 103, the first wing 101 of great thickness E1 and the second wing 102 of great thickness E2.
- This profiled 200 soyé plays a role of connection between the parts 111 and 110, such as parts of a plane.
- the linking seam 201 provides a gap between the first part 105 and the second portion 106 of the profile 200. This offset exists in relation to to a plane P of alignment between these two parts. This shift extends into the plane of the mast of the profile with a height H measured in one direction perpendicular to the plane of the wings and with a measured length L1 or L2 in a direction parallel to the plans of the mast and wings.
- the height H of the offset of the side of the wing of great thickness and that of the side of the wing of small thickness are identical.
- length L1 of the offset of the wing 101 of thick thickness is more large as the L2 length of the wing offset 102 of low thickness.
- the section 200 has a low slope, in the sinking 201, the side of the wing 101 of great thickness, and a steep slope, in the trimming 201, the side of the wing 102 of small thickness.
- the length L1 is proportional to the thickness E1 of the wing 101 and the length L2 is proportional to a thickness E2 of the wing 102.
- the lengths L1 and L2 are respectively equal to six times the great thickness E1 and to six times the small E2 thickness.
- this ratio varies depending on the nature of the material in which the profile 200 is made. So, the 201 grinding of slope strong side wing 102 thin, spread between the two parts 105 and 106, over a length L2 equal to six times the thickness of this wing of thin.
- the low slope 201 trimming on the wing side of large thickness is spread between the two parts 105 and 106, over an equal length at six times the thickness of this wing of great thickness.
- the relationship between lengths L1 and L2 and the thicknesses E1 and E2 can vary in a range real values between four and ten.
- projections end of the linkage 201, on the side of the steep slope are located between end projections of the linkage 201, on the side of the low slope.
- the ends of the squelch 201 on the side of the wing 102 thin are projected in one direction perpendicular to the wings 101 and 102, and in a direction from the small wing 102 to the main wing 101.
- the projections of these ends are located between projections of ends of the sear 201 on the side of the wing 101 of large thickness, in the direction perpendicular to the wings 101 and 102, and in a reverse direction from the large wing 101 to the small wing 102.
- a projection of one end of the 201, on the side of the steep slope, according to the direction and meaning mentioned above, is confused with a projection of one end of the srive, on the side of the low slope, in the opposite direction and opposite direction.
- These projections may result in the highlighting of a distance P1 and a distance P2.
- the distance P1 which extends into a direction parallel to the planes of the mast 103 and the wings 101 and 102, separates opposite ends of the seam 201.
- a distance P2 which extends into the direction parallel to the plane of the mast 103 and the wings 101 and 102, separates other opposite ends of the seam 201. In general, these distances P1 and P2 are different.
- the distance D1 or the distance D2 is zero. This realization is represented in discontinuous lines on the figure.
- the soyage 201 thus comprises a completely different geometry that of the trimming 104 of the section of FIG. 1. Indeed, the ends of the 210 form a quadrilateral 210, in which, unlike a quadrilateral associated with the sear 104, no side is parallel to another.
- the geometry of the jogging 201 is determined according to a congestion, a geometry of an external system, or stops surrounding the profile 300. This geometry can also be determined by compared to a mechanical reinforcement indicated in a specification.
- the space 130 between the profile 200 and the parts 121 and 122 is decreased to meet the requirements of an office studies. In one example, this decrease in space makes it possible to satisfy to constraints related to rigidity of assembly or resistance between parts 110 and 111.
- FIG. 3 shows steps of a jogging method allowing make the profiled section of Figure 2. It implements this method on a 300 straight profile comprising the wings 101 and 102 of great thickness and small thickness.
- a fixed anvil 301 is produced. having a segment 302 of steep slope which is spread between two parts 303 and 304 parallels along the length L2. This length L2 is proportional to a thickness E2 of the wing 102 of small thickness.
- This length L1 is proportional to a thickness of the wing 101 of great thickness.
- the lengths L1 and L2 of segments 302 and 312 of steep slope and slope low are respectively equal to N times the thickness of the wing 101 large thickness and N times the thickness of the wing 102 of small thickness.
- N is a real number which in an example is equal to 6. However, N varies depending of the nature of the material in which the profile 300 is made.
- FIG. 3a shows a step in which the wing 102 of small thickness of the profile 300 against the anvil 301. Then place the punch 311 against the wing 101 of great thickness of the profile 300.
- the ends of the slope segment 302 are placed strong so that projections of the ends of the segment of steep slope 302 in the opposite direction of a support, either located between projections in the direction of bearing the ends of the slope segment 312 low.
- the punch 311 is then in an initial position.
- a end of the slope segment 312 weak so that the projection this end is confused with a projection of one end of the sharp slope segment 302.
- a distance P1 is observed between one end of segment 302 of steep slope and one end of segment 312 of low slope.
- a distance P2 between another end of the slope segment 302 strong and another end of segment 312 of low slope. These distances are observed in a direction parallel to the plane of the mast 103 and wings 101 and 102. The length of these distances P1 and P2 can be adjusted thanks to the arrangement of holds 321 and 322.
- the holds 321 and 322 and the anvil 301 are fixed and are interconnected by the intermediate parts 330 can be integral with a frame.
- Figure 3b shows a step in which the punch is pressed 311, so that this punch 311 and the anvil 301 print their shape at 300.
- one removes the wedge 321 laterally and one exerts pressure forces on the punch 311.
- These pressure forces F1 are applied in a direction perpendicular to the plane of the wings 101 and 102 and in a direction going from wing 101 of great thickness towards wing 102 of small thickness.
- the shim 321 is not removed and the anvil slides between the two holds 321 and 322. More precisely, in this variant, the shim 322 does not move laterally to release the punch.
- the punch 311 then has a degree of freedom allowing it to slide between the shims 321 and 322.
- the shims 321 and 322 retain the punch 311 only during the time of its placement then allow its displacement during the support.
- F1 forces are applied locally in an area of segments 302 and 312 of slopes. Alternatively, these F1 forces are no only applied in the area of the 302 and 312 segments of slope but also in a zone framing these segments 302 and 312 of slope. In applying F1 forces in an area that frames segments 302 and 312, one can realize a more precise sowing, the slopes realized in the soyage being very clear.
- F1 forces can be generated using a press or cylinder. A screw or another mechanical machine exerting mechanical forces can also generate these forces F1.
- FIG. 3c shows a step in which the cast profile is disengaged the grip of the anvil 301 and the punch 311 used in the process.
- first opposing forces F2 are exerted F1 support forces, so that the punch 311 is no longer in contact with the profile 300.
- F1 support forces
- the shim 322 is not moved laterally and the punch slides vertically between shims 321 and 322 to return to initial position.
- the shims 321 and 322 then have a configuration ensuring a blocking the punch 311.
- the starting profile 300 is sowed according to the dimensions of the anvil 301 and the punch.
- the slopes are formed of side of the large wing 103 and the wing of small thickness 104.
- Ends jarring 210 form the vertices of the particular quadrilateral 210.
- the quadrilateral 210 has a side perpendicular to a horizontal plane.
- the punch 311 may comprise the segment 302 of steep slope which extends over a length proportional to a thickness of the wing 102 of small thickness.
- the anvil 304 then comprises the slope segment 312 weak spreading over a length proportional to a thickness of the wing 101 of great thickness.
- the profile 300 is then returned so that each its wings are opposite the segment of slope corresponding to it.
- the bead profile of the invention here has two wings but it could have more than two wings.
- the profile to soyer can for example include three wings or four wings parallel to each other, the profile sowed obtained with the same number of wings.
- the punch then has a shape adapted to the number of wings of the profile to soyer. In one embodiment particular, the punch has several levels the different wings of the profile.
- the profiling of the profile can be carried out cold or hot.
- the determining the temperature at which the profile is to be sailed depends on the shape of the section of this profile and the nature of the material in which this profile is made.
