Definitions

  • the invention relates to a set of two matrices intended for equip a press to shrink and / or crimp a tubular part according to the preamble of claim 1 (see for example GB-A-987 726).
  • the nozzle is generally provided with peripheral bosses, which are thus anchored in the material of the pipe by tightening said outer ring.
  • tools can be used with jaws which tighten radially on the ring.
  • a hydraulic press manual or not which has a head in which there are two facing dies, having a hollow imprint, one being immobilized while the other, movably mounted, is biased by the jack hydraulic press.
  • the known matrices can be of the type circular or polygonal (e.g. hexagonal), i.e. the two matrices closed one on the other form a surface cylindrical or polygonal tubular tightened in relation to the shape initial cylindrical of the ring.
  • pinching can be very important.
  • Document DE-B-1096442 describes a set of two matrices intended to equip a press to clamp a part, the dies having each a hollow imprint which extends laterally on each edge by a junction surface of the crenellated matrices forming teeth and gaps transverse to the axis of the impression so that said teeth are provided for overlap each other during translational reconciliation mutual matrices carried out by the press until said dies constitute the closed interior surface desired for the shaped product.
  • This device is intended to tighten a sleeve around of two cables and the footprint of each matrix is a part of polyhedron.
  • the set of two matrices according to the invention is defined in the claim 1.
  • claim 6 relates to a press hydraulic comprising a set of two dies according to the invention and claim 7 the use of such a game to perform a crimping of a cylindrical ring on a pipe.
  • the dimensions of the teeth of each matrix are identical while the central axis of the cylinder part or footprint of each matrix is determined by the intersection of the plane longitudinal of the matrix with the mid-tooth division plane of said dies so that the substantially cylindrical circular surface formed by matrices is obtained when the teeth of a matrix are nested to the bottom of the interstices of the other matrix.
  • the two matrices are identical to each other and are intended to be presented from the front, but returned one by relation to the other, so that the teeth of one fit in the interstices of the other.
  • the teeth are slightly chamfered or rounded as well as the bottom of each gap on its inner edge.
  • the matrices according to the invention are quite well suited, but not exclusively, to equip a hydraulic press of the type mentioned above and apply in particular to cold crimping a ring as mentioned above, for fixing a nozzle or fitting in a pipe.
  • the head 1 can open for the establishment matrices, the matrix 2 'being fixed here while the matrix 2 is mobile and can be requested by the piston 3 (figure 2) of a jack hydraulics fitted to the tool.
  • the matrix thus represented in FIGS. 5 to 7 comprises a tail 4 for mounting in the head 1 and ribs 5a, 5b of guidance.
  • the matrix 2 has a hollow imprint 6 of cylindrical shape circular which extends on the edges of its opening by a crenellated surface 7a, 7b forming teeth as shown, directed transversely to the axis of the imprint 6.
  • the surfaces crenellated 7a, 7b are therefore constituted by a succession of teeth and interstices.
  • the teeth and the interstices have the same dimensions while each surface is delimited by side by a tooth, for example 8a, 8b ( Figures 6 and 7) and on the other side by a recess 8'a, 8'b corresponding to the size of a gap ( Figures 5 to 7).
  • the surfaces 7a, 7b extend footprint 6 substantially tangentially and we can see also that the teeth have a slight chamfer.
  • the imprints 6 and 6 ' thus connected after joining the crenellated surfaces of each matrix constitute a surface of generally circular cylindrical shape, the teeth of one of the matrices coming into abutment at the end of race to the bottom of the interstices of the other matrix.
  • the planes containing the interior faces teeth of a matrix intersect with the corresponding planes of the other matrix at the junction generators by forming very open dihedral angles.
  • the rounded parts, noted R, of the interstices favor as for them shrinking without tearing material from the part to shape, without causing any rupture or corrosion, and further facilitate dislocation during separation of the dies.
  • Figures 3 and 4 show a pipe 12 in which we want crimp a ferrule or fitting 13 provided with a loose nut 14.
  • the connector 13 has bosses for slightly enter the pipe 12.

Claims (7)

  1. Matrizenpaar für die Ausrüstung einer Presse zum Reduzieren und/oder Crimpen eines metallischen Rohrstücks, wobei die Matrizen (2, 2') jeweils eine muldenartige Vertiefung (6, 6') aufweisen, die einen Teil eines Kreiszylinders bildet, der seitlich an jedem Rand durch eine gezahnte Fläche (7a, 7b) zur Verbindung der Matrizen verlängert ist derart, daß bei einer durch die Presse bewirkten gegenseitigen translatorischen Annäherung der Matrizen (2, 2') die besagten Flächen dazu bestimmt sind, sich miteinander zu verzahnen, während die Abmessungen der Vertiefungen und der gezahnten Flächen (7a, 7b) derart sind, daß die vollständig miteinander verzahnten beiden Matrizen eine innere Oberfläche bilden, die allgemein im wesentlichen kreiszylinderförmig ist, dadurch gekennzeichnet, daß die gezahnten Flächen (7a, 7b) jeder Matrize jeweils eine Vielzahl von Zähnen und Zwischenräumen bilden und die muldenartige Vertiefung (6) in ihrer im wesentlichen tangentialen Richtung verlängern, wobei die Ebenen, welche die Innenflächen der besagten Zähne einer Matrize enthalten, sich mit den entsprechenden Ebenen der anderen Matrize unter Bildung von Flächenwinkeln schneiden.
  2. Matrizenpaar nach Anspruch 1, dadurch gekennzeichnet, daß die Abmessungen der Zähne jeder Matrize identisch sind, während die Mittelachse (11, 11') des zylindrischen Teils oder der Vertiefung (6, 6') jeder Matrize durch die Schnittlinie der Längsebene (10) der Matrize mit der Teilungsebene (9) auf halber Höhe der Zähne der besagten Matrize derart festgelegt ist, daß die durch die Matrizen gebildete, im wesentlichen kreiszylinderförmige Oberfläche erhalten wird, wenn die Zähne der einen Matrize bis auf den Grund der Zwischenräume der anderen Matrize eingreifen.

Matrizenpaar nach einem der Ansprüche 1 und 2, dadurch gekennzeichnet, daß die beiden Matrizen (2, 2') identisch sind und daß ihre gezahnten Flächen (7a, 7b) durch eine Aufeinanderfolge von Zähnen und Zwischenräumen mit gleichen Abmessungen gebildet und an einer Seite durch einen Zahn (8a, 8b) und an der anderen Seite durch eine Vertiefung (8'a, 8'b) derart begrenzt sind, daß die beiden Matrizen (2, 2') dazu bestimmt sind sich einander gegenüberzuliegen, aber derart gegeneinander versetzt, daß die Zähne der einen auf die Zwischenräume der anderen ausgerichtet sind.
