Definitions

  • the invention relates to a set of two dies intended to equip a press to shrink and / or to crimp a tubular piece.
  • the tip is usually provided with peripheral bosses, which are thus anchored in the constituent material of the pipe by clamping said outer ring. It is also known in crimping to form said bossings at the time of tightening on the ring itself.
  • a manual or non-manual hydraulic press which comprises a head in which two opposite matrices are arranged, forming a recessed impression, one being immobilized while the other, mounted mobile, is solicited by the hydraulic cylinder of the press.
  • the two matrices tightened one on the other form a surface, for example substantially tubular cylindrical or polygonal, with the bumps close, but which is tightened compared to the initial cylindrical shape of the ring.
  • each matrix is aligned transversely, an element or reciprocally a space on one side of the median longitudinal plane of the matrix aligning with an element or conversely a space disposed of the other side of said plane.
  • the two matrices are distinct and require not only a specific manufacture for each of them but also the impossibility to interchange them, on the other hand, the EP-0 620 057-A describes an embodiment in which the two matrices are identical. However, in this case the dies are intended to be face, but returned with respect to each other, so that the teeth of one fit into the interstices of the other.
  • the inventors propose a set of dies of the aforementioned type with reference to the document EP-0 620 057 and in accordance with the preamble of claim 1, but which is remarkable in that for each matrix, the teeth and the interstices respectively arranged on one side of the median longitudinal plane of the impression, align with the interstices and the teeth respectively. arranged on the other side of said longitudinal plane.
  • each transverse end of each die begins identically, on one side of the median longitudinal plane of the impression, with at least one tooth portion and / or at least one interstice portion, and another side of said plane, reciprocally and vice versa, by at least a gap portion and / or at least a tooth portion.
  • each matrix is manufactured in one piece by molding.
  • the indentation of each matrix forms a uniform portion of a cylinder or polygon to form a cylindrical or polygonal uniformly substantially cylindrical complete impression.
  • the indentation of each die comprises at least two concentrically reciprocating cylindrical portions in the longitudinal direction and separated by at least one radial projection oriented towards the inside of the imprint.
  • FIGS. 1 to 6 there can be seen a matrix 1 intended to cooperate with an identical matrix in order to constitute a set of two matrices 1, 1 'as represented in Figure 5, said matrices being intended to equip a press to shrink and / or crimp a tubular piece.
  • the dies 1, 1 ' are advantageously obtained in one piece, by molding.
  • the matrix 1 has an indentation 2 in the form in the example of Figures 1 to 6, substantially a cylinder portion.
  • the impression 2 of the matrix is extended laterally on each edge by a junction surface forming a plurality of teeth 3 and interstices 4 (FIGS. 1, 2 and 4) of conjugate shapes.
  • FIG. 5 which represents, as already stated, two matrices 1, 1 'imbricated one in the other, it can be seen that the imprints 2 and 2' of these matrices then form a complete imprint, here substantially cylindrical uniform cylindrical .
  • the complete impression could be substantially tubular polygonal.
  • the teeth 3 and 3 'respectively of one of the dies 1 and 1' are interposed in the corresponding interstices of the other matrix so that in section there is practically a continuity of material.
  • the invention proposes a particular structure in order to use two strictly identical matrices while also making it possible to present them face to face, whatever their positions among the two possible relative positions which are turned by 180 ° relative to each other. 'other.
  • the teeth 3 and the interstices 4 are arranged on one side of the median longitudinal plane of the cavity 2, passing here through the longitudinal axis L shown in FIG. , align with the interstices 4 and respectively the teeth 3 disposed on the other side of said longitudinal plane.
  • each transverse end of the die starts identically, on one side of the median longitudinal plane of the impression, by at least a portion of tooth 3 and / or at least a portion of gap 4, and, on the other side of said plane, reciprocally and vice versa, by at least a gap portion 4 and / or at least a tooth portion 3.
  • the ends are also provided with only a portion of tooth 3 or gap 4.
  • FIG. 4 of the example shown with four teeth shows that, from one side to the other of the matrix and with respect to the transverse axis T, the teeth 3 closest to this axis are disposed of on both sides of it.
  • each matrix 1, 1' forms a uniform cylinder part, in addition to the fact that it could be, as already said, of a portion of polygon, the imprint may also vary in the longitudinal direction, as in the embodiment shown in Figures 7 to 9.
  • FIGS. 7 to 9 correspond to FIGS. 2, 4 and 6 respectively of the embodiment previously described.
  • the impression 2 "here is formed of several parts of concentric cylinders alternated in the longitudinal direction, the teeth and the interstices being offset in the transverse direction to ensure the continuity of the impressions.
  • the indentation 2 "comprises three parts of concentric cylinders 5" of the same diameter which are alternated and separated by two parts of cylinders 6 'of smaller diameter.
  • the cylinder parts 6 'could be inwardly projecting polygonal or other parts and in general, at least two concentric cylinder portions can be separated by at least one inwardly directed radial projection of the footprint.
  • a set of two dies of this type allows for grooves on the crimped part.
