Definitions

  • the invention relates to a method for identifying rotationally symmetrical pressed parts, in particular sleeves of hose fittings, by means of at least one row arrangement of individually exchangeable stamping dies running in the direction of the axis of symmetry.
  • Hose lines are understood to be a unit consisting of an elastic hose and two fittings mounted at the ends.
  • the label should contain the following information: manufacturer's label, year and month, maximum permissible dynamic operating pressure.
  • the marking is part of the safety regulations. It is important that the date indicates the manufacture of the hose line, i.e. the union of hose and fittings, and not the date of manufacture of the individual parts.
  • a hose fitting generally contains a tubular part with connecting elements for connecting the finished hose line to a pressure source and / or a consumer, and with a profiled end which is inserted into the hose end.
  • the elastomer surface layer of which was previously removed there is a sleeve which is pressed under high pressure onto the hose end and onto the profiled end of the tubular part located therein, as a result of which the hose is reliably pressed in.
  • Various radial presses are commercially available for such a process. Such a press is described by way of example in DE-PS 28 44 475.
  • the invention is therefore based on the object of specifying a method of the type described in the introduction, in which an additional method step and a special embossing device can be dispensed with and in which there is also a fixed time allocation between the manufacture of the hose line and its identification.
  • the object is achieved in the method described at the outset according to the invention in that the marking is produced during the pressing process of the pressed parts by a radial press with a plurality of pressing jaws which are arranged to be radially movable around the axis of symmetry and at least one of which has a pressing jaw in its working surface the row arrangement of the individually exchangeable embossing dies is provided.
  • the prescribed marking is thus generated by a single, already indispensable process step, namely by pressing the sleeve on. This does not require a special operation or a special stamping device with its own drive.
  • the method according to the invention also gives the possibility of providing both ends of the hose line, ie both sleeves, with the required identification.
  • This has the additional advantage that if the hose line is completely severed in the area of the hose, each of the two ends can provide information about the manufacturer and the characteristic data of the hose.
  • the labeling is also towards everyone Wear and tear that occurs in practice is safely protected and accompanies the hose line throughout its life like a birth certificate. Storage of large quantities of pre-stamped sleeves is completely unnecessary.
  • the radial degree of deformation of the pressed parts is chosen so high that its material flows in the axial direction over at least part of the stamping dies.
  • the image of the dies is surprisingly clear and unambiguous at the ends of the row arrangement of the dies; on the other hand, however, it also shows that the embossing was produced when the sleeve was pressed, so that the knowledgeable observer can recognize the temporal correspondence of presses and embossing.
  • the invention also relates to a radial press for carrying out the method according to the invention.
  • a radial press with several around the axis of symmetry of the press and the press part arranged radially movable and driven by drive means pressing jaws with work surfaces is known for example from DE-PS 28 44 475, but without any possibility of identifying the pressed parts.
  • such a radial press is characterized according to the invention in that a recess is arranged in at least one press jaw, which opens into the work surface, in that a row arrangement of plate-shaped stamping dies ( ⁇ stamping types '') is arranged in the recess, the stamping side of which in lies essentially in the working surface of the press jaw, the row arrangement running in the direction of the axis of symmetry, and in that the recess at the ends of the row arrangement is provided with flat and mutually parallel support surfaces for the support of the end stamps.
  • ⁇ stamping types '' plate-shaped stamping dies
  • the recess is preferably cuboid, the longest axis of the cuboid extending essentially parallel to the axis of symmetry of the press and the pressed part.
  • the ends of the recess lie opposite one another in the axial direction, the support surfaces lying essentially in radial planes.
  • embossing dies themselves have the shape of small cuboids, the largest, plane-parallel boundary surfaces of which directly abut one another in the row arrangement, as is known from so-called end scales.
  • the recess contains at one end a wedge-shaped pressure body, which on one side has a support surface for the abutting die and on its opposite side has a first inclined plane, which on a complementary second inclined plane in the press jaw is displaceable, such that the row arrangement of the dies can optionally be placed under pressure and relaxed by relocating the pressure body.
  • Such a wedge-shaped pressure body enables the large-area transmission of the forces exerted by the axial elongation of the pressed part on the stamping dies.
  • a radial press 1 which includes a rear flange plate 2 with a pressure ring 3, which is designed as a hollow piston and is surrounded by a cylinder 4 with a cylinder jacket 5, one between itself and the pressure ring 3 here includes invisible annular cylinder space.
  • the pressure ring 3 and cylinder 4 perform a relative telescopic movement to one another, which leads to a radial displacement of press jaws 6, which consist of a press jaw base body 6a and a (exchangeable) press jaw attachment 6b.
  • the pressing jaws 6 are explained below as a unit, the nature of the pressing jaw attachments 6b naturally being decisive for the pressing and embossing process.
  • the press jaws are equipped with work surfaces 7, which give the pressed part its final shape.
  • the pressure ring is provided on its inside with a conical control surface 8, on which the pressing jaws 6 are supported with their conical outer sides.
  • the pressing jaws 6 are supported on an abutment, not shown here, on which So-called sliding blocks 9 are attached, which are used for exact radial guidance of the pressing jaws 6.
  • Flange plate 2 and the not shown, also plate-shaped and congruent abutment are guided relative to each other by guide pins 10 and pressed apart by compression springs 11 when the hydraulic drive is relieved. The outward movement of the pressing jaws 6 into the position shown in the lower part of FIG.
  • the press jaw 6 abuts with its working surface 7 at the end of a hose line 14 shown in dash-dot lines, of which a section of the hose 15, the tubular part 16 are shown with a connecting element 17.
  • the tubular part 16 extends into the interior of the hose 15; in the area of the overlap is the sleeve 18, the pressing and labeling of which is at issue here.
  • the remaining press jaws have been omitted for the sake of simplicity.
  • a recess 19 is arranged in the press jaw 6, which, with the exception of its right-hand end, is cuboid and opens into the work surface 7.
  • the work area lies, more precisely, one of the narrow long sides of the cuboid cavity.
  • a row arrangement of platelet-shaped embossing dies 20 is accommodated in the recess 19, the embossing sides of which are provided with so-called "letters" (mirror image in FIG. 3).
  • the embossing sides 21 are essentially in the working surface 7 of the press jaw.
  • the "letters" are raised characters or numerals, as is known from embossing stamps, how they are used, for example, as "stroke numbers” and as they have previously been used in so-called embossing machines.
  • the dies usually consist of a wear-resistant and very hard manganese-vanadium steel (e.g. 90MnV8).
  • the required protrusion of the embossing letters or embossing numbers on the work surface 7 can be determined by simple tests.
  • the row arrangement of the dies 20 runs in the direction of the axis of symmetry S-S (FIG. 2), the course not having to be exactly parallel to the axis of symmetry S-S, but preferably being parallel.
  • the recess 19 is provided at the ends of the row arrangement with flat and mutually parallel support surfaces 23 (left) and 24 (right) for the support of the end dies 20a and 20b.
  • the recess 19 contains at its one (right) end a wedge-shaped pressure body 25, which has the one support surface on one side 24 for the abutting embossing die 20b and on its opposite side has a first inclined plane 26 which can be displaced on a complementary, second inclined plane 27 in the pressing jaw 6, in such a way that the row arrangement of the embossing dies 20 is caused by displacement of the pressure body 25 is optionally pressurizable and can be relaxed.
  • the end face of the pressure body 25, which is particularly visible in FIG. 3 is set back from the work surface 7, so that the pressure body 25 is not acted upon by surface forces of the sleeve 18, which loosens the dies would have consequence.
  • the pressure body 25 is mounted displaceably in the radial direction to the axis of symmetry S-S. From Fig. 2 it also appears that the pressure body 25 is associated with a clamping screw 27 mounted in the press jaw 6, through which the desired clamping effect can be brought about.
  • the clamping screw 27 is a pressure screw.
  • a pressure exerted on the end face e.g. also due to metal abrasion
  • the recess 19 in the press jaw 6 has a base 28 which serves to (indirectly) support the dies 20.
  • the interchangeable pressure plate 22 is located between the dies 20 and the base 28.
  • a pressure screw 29 is arranged in the bottom 28 in the center under the pressure plate 22, through which the pressure plate 22 can be raised so far relative to the bottom 28 when the press jaw 6 is removed that the dies 20 can be comfortably gripped by hand.
  • the dash-dotted rays symbolize the center lines and directions of movement of the individual press jaws 6.
  • the press jaw 6, drawn in full lines, contains the row arrangement of stamping dies 20. It is readily possible to provide further press jaws with corresponding recesses and stamping dies, for which purpose preferably the opposite one Press jaw is used. It is in particular possible to subsequently replace press jaws or press jaw attachments, even in existing machines, by press jaws or press jaw attachments which are provided with the row arrangement of press punches according to the invention. In this way it is easily possible to convert an existing press without an embossing device into a press with an embossing device.
  • Fig.5 the already pressed and provided with a marking 30 sleeve 18 ⁇ is shown, on which the information according to the DIN standard 20066 is included.
  • the line pattern on the sleeve 18 ⁇ indicates that a so-called "press pattern" is formed on the surface of the sleeve, the individual surfaces 18a of which represent the impression of the working surfaces 7. Between these surfaces are line-shaped areas 18b that have not been touched by the work surfaces 7.
  • the entire surface of the sleeve 18 ⁇ can, however, be described as essentially cylindrical. If the marking 30 is arranged slightly recessed in the surface, it is also very largely protected against mechanical damage.
