Definitions
- the present invention relates to a tubular molded part with sprayed-on Nerbmdungskupplungen and a nerfahr for the production of tubular molded parts with sprayed-on connecting couplings, wherein the molded part consists of an extruded plastic tube which has been subjected to continuous shaping from the outside by movable mold jaws, with at least one end of the plastic tube there is a male or female Neritatiskupplung with the features of the preamble of claim 1.
- Nerfahren for the production of tubular molded parts from extruded plastic, which by means of mold jaws a continuous shaping, e.g. Corrugations that are subjected to are known and are used in various areas for media promotion.
- connection e.g. shown in European patent application 0913242, by means of an interlocking connection.
- DE 10128220 discloses a method for attaching corresponding end parts during the production process and DE 4429504 shows a pipeline with a one-sided connection, which are provided for defined lengths.
- such pipe shaped parts for example corrugated pipes
- the shaped pipe pieces thus created are provided at their ends with commercially available couplings to be inserted into the pipe ends in order to find connection to further pipes, containers, pumps or the like.
- this involves additional effort when installing the pipe fittings and sometimes creates problems during assembly.
- the object of the present invention is to provide a molded tube part or a method for producing one which does not have the weaknesses mentioned and is easier to handle and assemble.
- a male or female connecting coupling is sprayed onto a tubular shaped part which, after the extrusion process in which it was subjected to continuous shaping, is sprayed on at least one end of the tubular shaped part thus created.
- the connection part to be sprayed is freely selected according to the
- a male connector can be sprayed onto one end and a female connector at the other end, or the same at both ends, creating a kind of extension or connector for processing as a media-carrying line.
- connections to the pipe fittings can be made quicker and easier, for example in the automotive sector as media-carrying lines, since the lines can be connected directly to containers, pumps or the like. There is no need to look for and insert the appropriate coupling pieces, as was previously the case, which caused problems especially in hard-to-reach places.
- the female connecting pieces sprayed onto the pipe fittings described are cylindrical and have an inner radial groove, which is preferably rounded. Sprayed-on male connecting pieces have an annular bead on the pipe piece to be inserted, which rises conically from the front and drops steeply from their maximum circumference and is provided with an undercut.
- the male connecting pieces are now inserted into the female and pushed against each other until the ring bulge of the male connecting piece engages in the groove of the female connecting piece in a sealing manner and lies against the circumferential groove.
- the pipe fittings used are preferably corrugated pipes in which wave crests with a smaller diameter and wave crests with a larger diameter alternate.
- the connecting pieces are preferably sprayed onto at least two wave crests and wave troughs, a wave crest from the tube forming the end opposite the sprayed-on connecting piece, as a result of which an optimal connection is achieved.
- the sprayed-on female connector has at least two bores with different diameters on the inside, of which the smaller one
- the front area of the female connector is conical to allow easier insertion of the male connector.
- the connecting pieces and the pipe fittings can be made of different materials.
- the materials of the connecting pieces can be chosen softer, for example to keep the effort required for plugging together low and to increase the tightness of the connections.
- the shaped pipe part described is produced in accordance with the explanations by extruding a plastic pipe, the pipe part being subjected to a continuous shaping, such as corrugated pipe, from the outside by movable mold jaws during the extrusion process and then being cut to the desired length.
- the pipe part produced in this way such as a piece of corrugated pipe, is then placed in a spraying device in which a connection piece to be provided is sprayed onto the pipe part, which may be a female or male.
- a connection piece to be provided is sprayed onto the pipe part, which may be a female or male.
- pipe fittings can be manufactured with the same fittings on both sides.
- the pipe piece with the sprayed-on connecting pieces is removed from the spraying device and can be used or further processed, for example by means of a further thermal shaping in which the shaped pipe part is adapted to the later intended use by forming bends, kinks and angles.
- 1 is a first sectional view of a female connector
- Fig. 3 is a sectional view through a connector and an adjoining pipe part.
- Fig. 1 shows a section through a female connector 1 with a schematically illustrated end of the molded tube part 2, which is molded around by the connector 1.
- the hole 3 in the connecting part 1 creates the transition to the cross section of the pipe molding 2.
- a corresponding male connector is plugged in via the double conical version Opening 4, and the annular bead of the male connector snaps into the groove 5 of the female connector 1.
- FIG. 2 again shows a section through a variant of the female connector 1 with a conical inlet 4 and the subsequent groove 5.
- Fig. 3 shows a further sectional view through the connecting part 1 and the tubular molded part 2, which has the wave crests 6 and troughs 7, and the transition 8 to the connecting part 1, which ends with a wave crest. It can also be seen that the pipe part is encapsulated by the connecting piece over at least two shaft crests and two wave troughs for better stability.
