Definitions

  • the present invention relates to a method for press fitting of an at least locally cylindrical part in a tubular piece, generally transversely by with respect thereto, according to the preamble of claim 1, as well as an assembly formed by two pieces fitted crosswise, according to the preamble of claim 10.
  • At least locally cylindrical part is meant here a part whose outer surface is, at least locally, at the level of its fitting with the tubular part, a cylindrical surface, i.e. a surface which, whatever the nature, circular or otherwise, of the outline of its cross section, is formed of parallel generatrices.
  • This at least locally cylindrical part which, by measuring convenience, will be hereinafter more simply cylindrical part, can be solid, hollow or tubular.
  • a hollow or tubular part it can serve as housing at least any other component.
  • tubular part a part, which, all by being generally elongated in the form of a tube, by being open to one at less of its ends, can be more or less conformed, being by more or less curved or curved example, and which, transversely, presents any section.
  • the assemblies formed of a cylindrical piece fitted in a cross in such a tubular piece can find for themselves their own application, in particular because of the particular assembly of the parts which constitute, but they can also find their application in the assembly of other components linked to one or other of these parts, by example in automotive construction.
  • this tubular piece forming, generally, around its hole, by the very fact of its tubular structure, two partitions, that of these partitions which, during the fitting of the cylindrical part, is located side of the engagement of this cylindrical piece cashes first of all the corresponding fitting force and is thus itself susceptible to be the object of some distortion.
  • the tools used for this make is a punch whose end is blunt in the shape of a blade, so that, during the formation of the fallen edge, the partition concerned is simply pushed back laterally, on either side of this blade.
  • the fallen edge obtained does not extend over the entire perimeter of the hole it borders, and, secondly, that, height null at the two ends of a diameter of this hole, its height varies from one to the other of these ends, to the detriment of the homogeneity of the reinforcement obtained for holding the cylindrical part in the tubular part, and therefore definitive, at the expense of this reinforcement.
  • the present invention generally relates to a provision to avoid such deformation and further leading to other advantages.
  • the contact surface between this tubular part and the part cylindrical is significantly increased, to the benefit of holding the assembly, and, preferably, there is formed such an edge fallen on one and the other of the partitions of the tubular part, over the entire perimeter of the hole corresponding, and of substantially constant height all around it.
  • the fallen edge (s) thus used can be formed by stamping, the spacer wedge present inside the tubular part forming therein a matrix suitable for allowing such stamping, without deformation of the partition concerned.
  • the spacer wedge is placed in the tubular piece before the formation of this hole, and a hole is formed, in this case a pilot hole, in this tubular part by simple die cutting of it.
  • the tools to be used for such a die cut is advantageously very simple and inexpensive.
  • this tool is advantageously likely to be used works on a standard machine, in this case a simple press, and, more particularly, on a simple hydraulic press, without any layout specific.
  • the present invention also relates to an assembly formed by two pieces fitted in a cross as defined in claim 10.
  • such an assembly is normally advantageously free from any deformation, the spacer spacer implementation effectively rebutted from the inside during engagement at least locally cylindrical part in the hole of the tubular part, that of the partitions of this tubular piece which is located on the side of this
  • an assembly 10 which, as is better visible in FIG. 1, is formed of two pieces fitted crosswise, namely a cylindrical piece 11 and a tubular part 12.
  • the cylindrical part 11 is, in a way general, defined as being a part whose external surface 13 is at less locally, at its fitting with the tubular part 12, a cylindrical surface.
  • this outer surface 13 is assumed to have a circular contour and to be keep on going.
  • cylindrical part 11 is also assumed to be full, like a bar.
  • the tubular part 12 meanwhile, has, overall, a direction of elongation D, towards which the generators of the surface outer 13 of the cylindrical part 11 extend substantially orthogonally.
  • This direction of elongation D is shown diagrammatically in lines interrupted in Figures 1, 2, 4A, 4B, 4C, 4D, 4E and 4F.
  • the length L1 of the tubular part 12 along its direction of elongation D may be greater or less.
  • the tubular part 12 is, at As an example, a slender piece, insofar as this length L1 is relatively large, especially compared to its width L2.
  • the cross section of the tubular part 12 can be any.
  • this cross section is, for example, largely flattened in a buttonhole, substantially perpendicular to the generatrices of the external surface 13 of the part cylindrical 11.
  • this cross section is uniform over the entire length L1 of the tubular part 12.
  • the cross section of the tubular part 12 can on the contrary be more or less modulated according to its length L1.
  • tubular part 12 is, for example, straight or substantially straight.
  • this tubular part 12 can just as easily be more or less consistent.
  • it can be more or less curved or curved.
  • the tubular part 12 has, overall transversely, and, more precisely, generally transversely by relative to its direction of elongation D, for the intervention of the part cylindrical 11, a hole 14, which envelops the overall contour of the part cylindrical 11, the cross member right through, and in which, according to arrangements described in more detail later, the cylindrical part 11 is forcibly engaged.
  • This hole 14 therefore affects either of the two partitions 15 that the tubular part 12 forms generally transversely around it, and, in the embodiment shown, it has a circular outline.
  • the hole 14 intervenes, by way of example, at a distance from both ends of the tubular part 12.
  • both partitions 15 of this tubular part 12 are substantially flat, at least at least near hole 14.
  • E be the internal thickness of the tubular part 12 at its hole 14, i.e. the distance internally separating one from another partitions 15 at the level of this hole 14.
  • a fallen edge 18, which, integral with this partition 15, extends in the direction of the other partition 15 of the tubular part 12, substantially perpendicular to this other partition 15.
  • a spacer block 16 is also inserted in the tubular part 12, also described in more detail later, capable of internally buttressing this tubular part 12 in the vicinity of hole 14.
  • a fallen edge 18 is formed over the entire perimeter of the hole 14.
  • the spacer block 16 inserted in the tubular part 12 intervenes at least in the direction of elongation D of it.
  • the spacer block 16 is circularly continuous and it therefore intervenes without discontinuity all around the hole 14.
  • a ring In the general form of a ring, it has, in plan, a overall outline generally similar to that of hole 14, and, of diameter greater than that of the latter, it extends coaxially around it.
  • the spacer 16 may, for example, have in axial section, a profile in rectangle or square, and, in practice, this profile can be the most commonly used, this spacer block 16 can for example be formed by a section of tube, preferably metallic, machined or not.
  • the spacer 16 has, in axial section, an isosceles trapezoid profile.
  • the spacer block 16 comprises, overall, in this embodiment, in addition to the flats 19, which truncate it transversely at its axial ends while being sufficiently wide so that its compressive strength is not compromised, on the one hand, an inner surface 20, which is generally cylindrical, and, on the other hand, a outer surface 21, which has a middle portion 22 itself generally cylindrical, and, each arranged respectively on the one hand and on the other, axially, from this middle part 22, two facets overall tapered 23.
  • the spacer block 16 used has preferably good compressive strength and good rigidity.
  • it is made of metal or synthetic material tough.
  • this spacer 16 being placed in place in the tubular part 12 before the formation of this hole 14, a pilot hole 14 ', in this tubular part 12, by simple die-cutting of it, Figures 4B and 4C.
  • a second advantage is then taken from the spacer 16, for the formation of the fallen edge 18.
  • this edge is preferably formed dropped 18 by stamping of the partition 15 concerned.
  • the spacer spacer 16 serves as a matrix for the relevant partition 15 of the tubular part 12.
  • a fallen edge 18 is formed on one and the other of partitions 15 of tubular part 12, on at least part of the perimeter of the hole 14, and, in practice, over the whole of it.
  • the spacer block 16 is inserted in the tubular part 12, along arrow F1 of this FIG. 4A, being introduced into this tubular part 12 from one of the ends, from this, until it comes substantially to the right of the location provided for the hole 14 to be formed.
  • this insertion can advantageously be done without high precision, the spacer 16 coming from itself is centered by relative to this location when the hole 14 is formed.
  • the spacer 16 has a height H substantially equal to the internal thickness E of the tubular part 12, or even slightly greater than this thickness E, so that it is forcibly engaged between the two partitions 15 and that it is therefore duly stuck between them.
  • maintaining the spacer block 16 in position can be insured, or strengthened, by other means, and, for example, by means mechanical, such as fingerprints obtained by local stamping of the tubular part 12.
  • FIGS. 4B to 4E the training is carried out from hole 14 and that of the fallen edges 18.
  • the tools used for this purpose operate in practice on a standard machine, in this case a simple hydraulic press.
  • This tool 25 comprises, successively, bottom to top, a first stepped punch 26 having a first section 27, by the free end 28 from which it is able to cut a pilot hole 14 'to the cookie cutter, a second section 29, with progressive transverse profile, by which it is capable of ensuring a stamping, and a third section 30, by which it is able to perfect this stamping.
  • the diameter D2 of the first section 27 is much smaller than that D1 of the hole 14 to be formed, while the diameter D3 of the third section 30 is substantially equal to this diameter D1, while being slightly less than this.
  • the free end 28 of the first section 27 of the punch 26 is circularly divided into at least two lips 31, the edges are connected in continuity with each other and thus form the thread or cutting edge of the whole.
  • dihedral 32 which is concave, and of which the edge extends substantially transversely relative to the axis of the punch 26.
  • the first section 27 of the punch 26 therefore generally has a inverted V configuration.
  • each of its lips 31 is cut transversely by a flat 33.
  • the tool 25 also includes, for buttressing the part tubular 12 to be worked, a matrix 34 hollowed out of a hole 35 whose diameter D4 is substantially equal to the diameter D2 of the first section 27 of the punch 26 while being slightly greater than this diameter D2.
  • the punch 26 which extends directly above the hole 35 of the die 34, is controlled to move in the direction of the latter, along arrow F2 of Figure 4B.
  • the punch 26 successively ensures, first of all, the cutting of the other partition 15 of the tubular part 12, called below first partition 15, FIG. 4B, with a slight inward folding from the edge 18 ′ thereof intended to form a fallen edge 18, then the cutting of the second partition 15, FIG. 4C.
  • waste 36 from the first partition 15 of the tubular part 12 remains temporarily attached thereto, so that it is not not likely to interfere with the route of this first section 27 before this only attacks the second partition 15 of the tubular part 12, which avoids that it can inadvertently disturb the cutting of the latter.
  • the waste 36 After detaching from the first partition 15, the waste 36 is discharged through the hole 35 of the matrix 34, together with the waste 37 in from the second partition 15, FIG. 4C.
  • the punch 26 completes the inward drawdown of the fallen edge 18 from the first partition 15, and, as shown in Figure 4C, this drawdown is then confirmed by the third section 30.
  • the tool 25 includes a second punch 38 capable of ensuring then successively a stamping and a calibration of the tubular part 12.
  • the tubular part 12 is placed on a new matrix 39 perforated with a hole 40 whose diameter D5 is substantially equal to that D1 of the hole 14 to be formed while being slightly greater than the latter.
  • the second punch 38 is a floor punch.
