Definitions
- Tubular coupling part for producing an adhesive connection with a fluid line
- the invention relates to a tubular coupling part for producing an adhesive connection with a fluid line, the coupling part consisting of an inner tube which can be inserted into the fluid line and an outer tube which is formed concentrically therewith and which is formed on the rear end of the inner tube with a closed ring.
- Such a coupling part is known from DT 26 03 299 A1, in which the annular gap between the inner tube and the outer tube is filled with liquid adhesive, in such an amount that the spaces between the fluid line and the inner tube or the outer tube are fully filled after pressing the fluid line.
- the adhesive consists of two liquid components that are held in the annular gap by removable separating and covering foils.
- This method of working with liquid adhesive components has the disadvantage that the films must first be removed at the construction site before the pipe end of the fluid line can be inserted into the annular gap.
- the pipe end and the coupling part must be kept in an axially aligned position until the adhesive mass has solidified. It also requires great attention when filling in the adhesive components, with the correct dosage and with the airtight sealing of the annular gap.
- Such a tubular coupling part is also known from DE 44 42 407 C1, in which the annular gap is filled with a hardenable sealant or binder and then closed with a releasable, airtight cover.
- the cover film on the construction site must first be removed before the pipe end of the fluid line can be inserted into the annular gap in order to produce an adhesive connection.
- the object of the invention is to design and fill the annular gap using a suitable adhesive in such a way that the coupling parts can be connected quickly and easily to the end sections of the fluid lines.
- it is proposed to fill the annular gap between the inner tube and the outer tube with a dry, meltable adhesive pressed as a solid ring.
- the design of the inner tube according to claim 2 should serve the end region of the fluid line as a centering system, while the hot melt adhesive can be distributed between the longitudinal ribs.
- the design of the outer tube according to claim 3 also ensures that the adhesive used between the inner and outer tubes can swell well along the grooves when melting and thus ensures a uniform distribution of the adhesive.
- the proposed method for producing an adhesive connection according to claim 4 also provides an advantageous procedure for how the adhesive ring introduced into the annular gap is rapidly heated during the insertion of the fluid line and the end of the fluid line can be well pressed into the melting adhesive.
- Fig. 1 shows a clutch housing in side view with partial section through
- Fig. 3 shows a pressed adhesive ring for insertion into the annular
- Fig. 7 shows the coupling part glued to the fluid line.
- FIG. 7 shows a tubular coupling part 1 which is connected in one piece to a coupling housing 2 made of plastic.
- This coupling part 1 serves, as can be seen from FIG. 7, to produce an adhesive connection with a fluid line 3, which, for example. can be formed from aluminum tube or from any other suitable metal tube.
- the coupling part 1 can, however, also be integrally formed on a plug-in part, not shown in the drawing, which is introduced into the coupling housing 2 in a known manner to produce a detachable plug connection.
- the coupling part 1 consists of an inner tube 4, which is inserted into the free end 20 of the fluid line 3, and of an outer tube 5, which is formed concentrically with this and which is connected to the inner tube 4 at the rear end thereof via a closed ring 6.
- the inner tube 4 has on its outer jacket 7 at least three longitudinal ribs 8, which serve the inner wall 9 of the fluid line 3 as a centering system when it is pushed over the inner tube 4 (FIG. 6).
- the outer tube 5 has on its inner side distributed over the circumference a plurality of axially parallel grooves 10, the ridges 11 of which have an inner diameter d2 which is slightly larger than the outer diameter D of the fluid line 3.
- the outer tube 5 is expediently approximately flat. as long as the outer diameter D of the fluid line 3, while the inner tube 4 is approximately half longer than the outer tube 5.
- the annular gap 13 between the inner tube 4 and the outer tube 5 is filled approximately halfway with meltable adhesive, which is entered in the form of a firmly pressed ring 14 (FIG. 3).
- the outer diameter D1 of this ring 14 is dimensioned somewhat smaller than the inner diameter d2 of the combs 11, while the inner diameter d1 of the ring 14 corresponds approximately to the inner diameter d of the fluid line 3.
- the width B of the ring 14 is finally dimensioned such that the ring 14 fills approximately half the depth of the annular gap 13.
- the ring 14 After the ring 14 has been inserted into the annular gap 13 in the direction of the arrow P, the ring 14 is expediently pressed using an auxiliary tool 15, which has a number of pressure stamps 16 distributed over the circumference, until it abuts the connecting ring 6 (FIG. 4).
- the coupling part 1 filled with adhesive is now ready to be glued to the free end 20 of the fluid line 3.
- the workflow is illustrated in FIGS. 5 and 6.
- the coupling housing 2 is first held in position with a coupling holder 17, while the fluid line 3 is brought into a counter position by an extension of the tube 18. Now the free end 20 of the fluid line 3 is surrounded by an induction coil 19, so that the tube end 20 can be preheated (FIG. 5).
- the coupling part 1 is then pressed by means of the holder 17 in the direction of arrow M onto the free end 20 of the fluid line 3 and at the same time is immersed in the induction coil 19. Due to the heat from the induction coil, the adhesive ring 14 is melted. While the pipe end 20 of the fluid line 3 penetrates into the hot melt adhesive, it is pressed out in the insertion direction M due to the material displacement on the inner wall 9 and the outer wall 12 along the ribs 8 or grooves 10, the spaces between the pipe end 20 and the coupling part 1 being complete must be filled in (Fig. 6).
- connection process between the coupling part 1 and the fluid line 3 is completed to the extent that the brackets 17 and 18 can be removed for the curing process that may be required. (Fig.7).
- the coupling 2 with the glued-on fluid line 3 can then be used for its intended purpose.
- the tube holder 18 is symbolically represented by a solid body with a so-called blind hole, into which the fluid line 3 is inserted with the end leading away.
- the pipe holder can also be used as a clamping body spanning the fluid line 3, such as a pipe clamp, which is particularly advantageous if the fluid line 3 has a greater length than is shown in FIGS. 5 and 6.
