Definitions
- the present invention relates to a connecting device for media, in particular hydraulic flow media, consisting of a connecting part made of plastic with at least one connecting portion having a receiving opening for a tubular, to be welded by laser beam line end.
- DE 10 2006 034 697 A1 describes a plastic line with a directly welded to a line end connector part in the form of a hydraulic angle connector or a plastic housing of another hydraulic element.
- the plastic line and / or the connecting part should be made of a transparent plastic material for laser beams, wherein in addition all components (connecting part and line) should be formed from the same plastic material.
- the embodiment which is transparent to laser beams excludes certain applications because, because of the required laser transparency, certain plastic components, such as reinforcing materials (eg glass / carbon fibers) and additives (eg color pigments and in particular carbon black as UV protection), do not or may be limited because such moieties would affect laser transparency to the extent that the material would be less or no longer laser transparent.
- certain plastic components such as reinforcing materials (eg glass / carbon fibers) and additives (eg color pigments and in particular carbon black as UV protection)
- additives eg color pigments and in particular carbon black as UV protection
- the present invention is based on the object to provide a connecting device of the type mentioned, with which, despite the possibility of welding by laser welding a design of the connection part for almost any application is possible.
- connection part consists of at least two components with different material properties, wherein a first component encloses the receiving opening in the region of the connection section and consists of a material largely transparent to laser beams.
- the other, second component can be designed with respect to its material properties for virtually any application-dependent requirements, advantageously independently of its effect for laser beams.
- the second component can be designed in particular to be laser-absorbent (not laser-transparent).
- the second component may contain any, application-dependent material components, in particular any reinforcing materials (eg glass / carbon fibers) and / or certain, eg. B. property-modifying additives.
- connection device 1 is a connection device according to the invention in a
- FIG. 7 shows a further alternative embodiment in a view analogous to FIG.
- FIG. 8 to 10 representations analogous to Fig. 6 in further embodiments.
- a connecting device 1 consists of a connecting part 2 made of plastic.
- the connection part 2 has at least one connection section 4 with a receiving opening 6 for a tubular, to be welded by laser beam line end 8.
- the line end 8 may - as shown - be an end portion of a pipe or hose made of plastic or a component of any other connection or assembly part, in which case the connection part 2 z. B. at the end of a pipe or hose (fixed / formed) is.
- the line or the line end 8 may be circular or non-circular in cross-section, z. B. oval or polygonal, be formed.
- connection part 2 consists of at least two components K1, K2 with different material properties.
- a first component K1 surrounds the receiving opening 6 in the region of the connection section 4 and consists of a material that is largely transparent to laser beams.
- the other, second component K2 may consist of a laser-absorbing material, which may therefore contain any selected according to the application-dependent requirements material proportions.
- the second component K2 consists of a polyamide, wherein this base plastic may have, for example, for the following application-dependent requirements certain material portions or additives mentioned in parentheses:
- Mechanical strength (reinforcing materials, in particular organic and / or inorganic materials, such as fibers of glass, carbon and / or flax, glass beads, mica flakes), the choice of additives being made in accordance with the following parameters: strength (tensile strength), compressive strength ( Bursting pressures), toughness, stiffness, elasticity (for example in the case of rockfall), hardness
- UV protection (soot, pigments, nano-pigments)
- the wall thickness is also to be considered in addition, because the laser transmission decreases upon irradiation after an e-function.
- R + A + T 100%, where R is the reflectivity, A is the absorption and T is the transmission.
- the interpretation should be such that R is less than 20%.
- the radially measured wall thickness of the laser-transparent component K1 should preferably be in the range of 1 mm to a maximum of 5 mm.
- the fiber content should be at most about 30%, depending on the material thickness to be irradiated (eg at 1 mm about 30% and at 5 mm at most 10% up to 0%).
- the second component K2 arbitrary fiber content of z. B. 20% to 60%.
- the component K2 adjoining the laser-transparent component K1 is designed as a connector part with (at least) one connector shank 10, for example in the form of an angle connector as shown in FIG.
- at least one plug-in socket can also be provided for inserting a plug shank of a further connector part.
- a training as T-piece, straight through connector, distributor or any angle piece is possible.
- an inner media channel 12 of the connecting part 2 is completely enclosed over its entire course length up to an inner, plug-in end region of the receiving opening 6 for the line end 8 of the material of the second component K2.
- the inner end of the receiving opening 6 is formed by a radial contact stage 14, at which the inserted line end 8 comes to rest.
- the inner media channel 12 passes directly into the line end 8, so that in this area of the media channel 12 is completely enclosed on the one hand by the material of the second component K2 and on the other hand by the material of the line end 8.
- the connecting device 1 is also suitable for media which, for example, must be protected from external UV radiation.
- the second component K2 and the line end 8 are designed with corresponding proportions of material which ensure UV resistance. This is achieved in particular by a black color.
- connection part 2 is formed with its components K1, K2 as a one-piece multi-component molded part (injection molded part).
- the components K1, K2 are materially homogeneous, materially connected to each other homogeneously.
- the first component K1 may also be designed as originally separate, ring-shaped or sleeve-shaped element, which is then welded during the welding process on the one hand to the line end 8 and on the other hand to the second component K2.
- the first component K1 covers the region of the front end of the inserted line end 8 axially in both directions. It is also possible to manufacture in such a way that one of the two components (in particular K1 or K2) is inserted as a separately preformed part into an injection mold and then the other component (K2 or K1) is injection-molded.
- the welding takes place in particular radially in the peripheral region between the line end 8 and the receiving opening 6. Additionally or alternatively, axial welding in the region of the system stage 14 and the adjacent front end of the line end 8 can take place.
- a plastic layer 16 to be arranged which consists of a material to be melted by laser beam.
- a plastic layer 18 can also be arranged radially between the receiving opening 6 and the line end 8.
- the embodiments of FIGS. 3 and 4 can also be combined with each other, d. H. Both layers 16 and 18 may be provided simultaneously.
- the plastic layers 16, 18 may be designed as a film, sleeve, coating, printing or vapor deposition.
- a hollow cylindrical section for example, is still radially between the first component K1 and the receiving opening 6 second component K2 arranged.
- This section forms a melting zone 20 for the purpose of welding to the line end 8.
- the first component K1 has a cylindrical outer surface 22 in an area axially covering at least the receiving opening 6.
- a laser beam 24 can thereby be aligned perpendicular to the longitudinal axis 26 of the receiving opening 6 or of the connection section 4 and thus radially and also perpendicular to the outer surface 22.
- the lowest possible reflection is achieved in order to allow the largest possible portion of the laser beam to penetrate the welding zone 28 in the radially between the receiving opening 6 and the line end 8.
- the first component K1 has a conical surface 30 such that a laser beam 24 aligned obliquely to the longitudinal axis 26 and perpendicularly striking the conical surface 30 passes through the first component K1 penetrates to a welding zone 32 which lies axially between the stop step 14 formed in this case by the first component K1 and the front end face of the line end 8.
- the line end 8 can also be welded axially.
- FIG. 8 an embodiment variant is shown in which the two components K1 and K2 are connected via, for example, conical interfaces 31, that the laser beam 24 initially radiated radially into the outer surface 22 of the first component K1 by reflections at the interfaces 31 in the Area of the axial weld zone 32 is directed.
- the outer surface 22 or the conical surface 30 is formed "relatively smooth", that is with a maximum roughness, as is common or achievable in injection molded parts.
- the laser beam 24 can also be aligned obliquely to the respective surface 22/30. Moreover, it is possible to make the respective surface convexly curved, in particular in the radial and / or axial section, in such a way that a lens effect for concentrating the laser beams is achieved.
- a circumferential direction is completely around the welding region extending bead 33 is formed so that the laser beam 24 impinges on a convex curvature in the axial section of the laser-transparent component K1 and thereby focused in the welding zone 28 into (bundled) is.
- overheating of the outer surface 22 is advantageously avoided; the heat is concentrated on the welding zone.
- the laser beam 24 is moved around the longitudinal axis 26 (see the arrow 34) during the welding process in order to weld the line end 8 tightly over its entire circumference.
- a mandrel 35 can be inserted from the inside, in particular through the connection part 2, into the region of the welding zone 28, wherein the support mandrel 35 is in particular characterized by a slight diameter oversize. firmly presses the line end 8 radially from the inside into the component K1. This also contributes to a high quality of the welded joint.
- the mandrel 35 may be flexible (flexible) so that it can be inserted through the connector 2, including of course the media channel 12 must be continuously formed - even in the angular range - with the same inner cross-section (arc-shaped).
- connection part 2 in the region of the component K2 lying outside the connection section 4 can have an arbitrary surface, for example also rib projections 36 for holding heating wires 38 of an electrical heating device.
- This embodiment is particularly advantageous for an application in which a gefriergefährdetes medium through the connection part 2 and its media channel 12 is to be performed, as is the case for example with water pipes for windscreen washer systems in motor vehicles and in lines for a urea solution, which is NO x - Reduction additive for diesel engines with so-called SCR catalysts is used.
- the components K1 and K2 are designed so that they differ from each other in their external appearance. This can be achieved for example by a different reflection behavior for the spectrum of visible light, in particular by different colors.
- the first component K1 thus the welding zone is marked, in which the laser beam is to be supplied.
- the component K1 additionally serves as an indicator of the weld zone.
- it indicates the nature of the connection part 2 compared to other types, eg. B. molded connection parts.
- the invention leads to the significant advantage that by far the largest part of the connecting part 2, namely the second component K2, is freely composable in its material composition and can contain any reinforcing substances and / or additives.
- the connecting part 2 namely the second component K2
- the laser-transparent component K1 allows optimum welding in the laser beam welding process.
- the invention is not limited to the illustrated and described embodiments, but also includes all the same in the context of the invention embodiments. Furthermore, the invention has hitherto not been limited to the feature combination defined in claim 1, but may also be defined by any other combination of specific features of all individually disclosed individual features. This means that in principle virtually every individual feature of claim 1 can be omitted or replaced by at least one individual feature disclosed elsewhere in the application. In this respect, the claim 1 is to be understood only as a first formulation attempt for an invention.
