Definitions

  • the present invention concerns a method of disposing at at least one end of a metal pipe of any length and with a constant cross- section a first rapid coupling half which can be coupled to a second rapid coupling half which is separate from the first rapid coupling half.
  • the invention also concerns a first rapid coupling half which is arranged according to this method in the end of a metal pipe of any length and having a constant cross-section, which rapid coupling half can be coupled to a second rapid coupling half which is separate from this first rapid coupling half.
  • the invention concerns a pipeline for conveying a medium in a vehicle, which pipeline is essentially produced from a metal pipe of constant cross-section and with a first rapid coupling half which is disposed in at least one end and which is adapted to be connected to a second rapid coupling half which is separate from this line.
  • a great number of rapid couplings of the above-mentioned type for joining together two metal pipe ends or for connecting a metal pipe end to the equipment of a hydraulic component or hydraulically-operating machine are already known and display the common characteristic that, unassembled, they produce a separate component.
  • a friction and/or clamp fitting, screwthreaded fitting or soldering for example, the male and female parts of the coupling are connected to the respective pipe ends.
  • WO 93/13347 discloses a rapid coupling for connecting two fluid- conveying, mutually leaktight pipes.
  • the first pipe has an end with a varying cross-section which is connected to a locking sleeve.
  • the pipe end and locking sleeve together form a first rapid coupling half.
  • a second rapid coupling half is disposed at the end of the second pipe.
  • One object of the present invention is to provide a method of the initially-mentioned type, which does not entail the above disadvantages. This object is achieved in that the first rapid coupling half is formed in one part with the metal pipe, and in that the first rapid coupling half is formed by cold-shaping of the pipe end.
  • a further object of the invention is to provide a coupling produced according to the method of the invention.
  • Such a coupling is characterized in that the first rapid coupling half is produced in one part with the metal pipe.
  • a third object of the invention is to provide a pipeline of the initially-mentioned type.
  • the line is characterized in that the first rapid coupling half is produced in one part with the metal pipe by cold-shaping of one end of said pipe, and that the length of the metal pipe is adapted to the distance over which the medium is to be conveyed in the vehicle.
  • the method according thereto permits rapid, functionally reliable and cost- effective connection of one metal pipe to another or to the equipment of, for example, a hydraulic component or machine, such as a fluid pump.
  • Figures la show schematically in longitudinal section a and lb female and a male part, respectively, of a rapid coupling produced according to method of the invention
  • Figure lc illustrates the female and male parts of Figures la and lb coupled to each other;
  • Figure 2a shows a female part produced in the equipment at the opening of a duct, for example, of a hydraulic component

  • Figure 3 shows an embodiment of a pipeline according to the invention.
  • 1 generally designates a metal pipe which, in the original state, has a circular constant cross-section, i.e. unvarying outer and inner diameters along the entire extension of the pipe.
  • the metal pipe enters a pipeline 10 for conveying a medium in a vehicle.
  • the length and shape of the pipeline are adapted to its area of application, which also necessitates corresponding adaptation of the metal pipe.
  • Figure 3 shows an embodiment of a pipeline according to the invention.
  • the metal pipe 1 is connected to at least one end 11 of a first rapid coupling half la which is formed in one part with said metal pipe.
  • This rapid coupling half la is adapted for connection to a second coupling half which corresponds to the first coupling half and which is separate from the metal pipe.
  • the rapid coupling half is shown as a male part.
  • the pipe end 11 is cold-shaped. Cold-shaping is performed at the end of the entire metal pipe length which is adapted to enter this pipeline. The cold-shaping can be performed before or after possible bending of the metal pipe.
  • Figure lb shows a rapid coupling half la which is produced by the method according to the invention and is in the form of a male part.
  • the cold-shaping of the pipe end 11 produces peripheral tracks at a predetermined distance from the pipe opening.
  • O-rings are disposed in the outer peripheral track lal, la2, whilst the innermost peripheral track la3 forms a seat for a lock ring 6b fitted onto this male part.
  • this section of the pipe receives a varying cross-section.
  • the conveying of medium in the pipeline 10, however, is not prevented by the cold-shaped pipe end.
  • the male part la is adapted so as to enter a corresponding female part 2a, 2b, 2c which is separate from the metal pipe.
  • the female part can, however, also be produced in one part with the metal pipe of any length by cold-shaping of the end thereof.
  • the female part can also be a detachable nipple intended to be mounted, for example by means of a screw connection, in a machine shown as a dashed rectangle in Figure 2b, to which the pipe is to be connected.
  • the most economical solution can be to produce a female part at 2c, as illustrated in Figure 2a, by machining directly in the machine equipment 4 (shown in section in Figure 2a).
  • Figure lc shows the rapid coupling halves la, 2a according to Figures la and lb in the coupled position in which the O-rings 5a, 5b ensure leaktightness between the male part la and the internal wall of the female part 2a.
  • a snap component Disposed between the male and female parts la, 2a in order to hold these parts in a relative position which ensures reliable tightening is a snap component which, in the examples of the female part shown in the drawings, is produced by a flange 6a, which points radially towards the opening in the female part, and by a lock ring 6b which is fitted on the male part la and which is secured by means of an annular flange 6bl which projects into the innermost peripheral track la3 of the male part.
  • the flange 6a can, in known manner, engage a corresponding cut-away section 6b2 in the lock ring 6b.

Abstract

L'invention concerne un procédé servant à monter à au moins une extrémité (11) d'un conduit en métal (1) de n'importe quelle longueur et de section transversale constante un premier demi-raccord rapide (1a) qu'on peut accoupler à un deuxième demi-raccord rapide (2a) séparé du premier. De ce fait, les demi-raccords rapides (1a, 2a) sont fabriqués en un seul ensemble avec les conduits en métal respectifs (1, 2) par façonnage à froid des extrémités (11, 21) des conduits (1, 2). L'invention concerne également un premier demi-raccord rapide (1a) monté d'après ce procédé à l'extrémité (11) d'un conduit en métal (1) de n'importe quelle longueur et de section transversale constante. On peut accoupler le premier demi-raccord rapide (1a) à un deuxième demi-raccord rapide (2a) séparé du conduit en métal (1). Le premier demi-raccord rapide (1a) se fabrique en une seule pièce avec le conduit en métal (1).
