Description

Profile machining device

The invention relates to a profile processing device. In particular, the invention relates to a processing device for shell-side cleaning or

Coating pipes and other elongated profiles.

From DE 10 2009 048 203 A1 a device for applying a

Corrosion coating on pipes and other elongated profiles known.

In particular, the device serves to apply viscous anticorrosion agents, which are produced in particular based on water or dry quickly, in low thickness on the lateral surface of the tubes or the profiles. It is this a comparatively compact building

Coating head provided with a filled with the anticorrosive bath. The anticorrosion agent exits the bath via an annular gap formed between the device and the profile on the input and output side and is collected via a labyrinth seal arrangement.

The coating device has proven itself in practice fundamentally.

In particular, finite length tubes can be effectively, quickly and inexpensively coated. To pipes by means of the same coating device or to treat profiles with a different cross-section, the device must be rebuilt to the effect that on the respective pipe or profile tailored panels are replaced on the coating head and the labyrinth seal is adjusted accordingly.

Object of the present invention is to develop a profile processing device such that a conversion of the device for different types of profiles deleted. Next, the device should equally be used to coat or clean profiles.

To achieve the object, the invention has the features of claim 1.

The particular advantage of the invention is that the elongated process chamber encompasses a portion of the profile to be machined on the shell side. The processing fluid provided on the shell-side feed opening into the process chamber serves to coat or clean the profile. In this respect, different depending on the application

Used processing fluids and introduced in different ways or quantities in the process chamber. The profile can be

be continuously introduced via the end-side passage openings of the process chamber in this same. With regard to their cross section, the

Through openings so dimensioned that the largest, to be processed in the process chamber profile cross section can be passed through the passage openings. A conversion to the process chamber when processing different profile diameter is not necessary so far.

The profile processing device operates in particular continuously in

A continuous process. Pipes of finite length and with any, solely by the inner dimension of the process chamber or the cross section of the

Through holes limited diameter can be connected to each other frontally and the process chamber fed continuously. In each case it can be provided that the profiles are either cleaned or coated in the process chamber. For example, the profiles can be coated with a corrosion inhibitor, a lacquer or a polymer. In this respect, particles can be introduced into the process chamber by means of a carrier fluid. For example, the Profiles are cleaned by a used in the manufacture of the same drawing agents, such as an oil or a phosphate soap. In accordance with the object, a suitable processing fluid - pure or as a mixture of a plurality of substances - is introduced into the process chamber. For example, paraffin, biodiesel, acids or surfactant mixtures are used for degreasing or de-oiling the surfaces of the profile sections.

A length of the process chamber is determined such that the machining fluid at least in the middle region of the process chamber completely surrounds or wets the profile section. The filling level then falls in the direction of

Through openings and the processing fluid supplied via the feed opening exits the front side via the passage openings from the process chamber. The

Processing fluid is collected after entering the collection chambers and exits through the drain holes. In particular, in the process chamber can be dispensed with separate drainage openings for the machining fluid or an overflow to limit a liquid level. The passage openings can be provided insofar as the only outlet openings for the machining fluid. They serve insofar on the one hand to bring the profile in the process chamber or to remove from this. On the other hand, they serve to remove the machining fluid from the process chamber.

The supply of the machining fluid via a shell side at the

Process chamber provided feed opening and a feed opening associated with the fluid supply. The fluid supply unit has, for example, at least one annular feed for the processing fluid, which surrounds the process chamber on the casing side. In this case, a plurality of supply openings can be provided distributed in the circumferential direction of the process chamber, which are assigned to the ring feed such that the processing fluid passes from the different sides into the process chamber via the ring feed and the feed openings provided on the shell side. It is thereby favored a good wetting on the surface of the profile, which is advantageous both in the field of cleaning the profile and the surface coating.

For example, adjacent to the ring feed, at least one further ring feed can be provided as part of the fluid feed unit. By providing at least one further ring feed can in particular the amount

or the pressure of the introduced into the process chamber

Machining fluid selected task specific or adapted. For example, a profile may be cleaned by supplying the cleaning fluid as a high pressure machining fluid. The processing fluid is in this case, for example, impulsive in the process chamber or sprayed onto the profile. It then forms a flow along the lateral surface of the profile section in the direction of the passage openings, which favors the cleaning of the profile. When coating the profile, it is advantageous to introduce a large amount of machining fluid into the process chamber and to guide the profile as completely as possible through the machining fluid. However, the processing fluid need not have any particular pressurization in the coating. By the

Fluidzuführeinheit has different ring feeds, the quantity or the pressure of the machining fluid can be adjusted individually by connecting or disconnecting individual thereof

be selected task-specific.

An optimized process design may be formed by providing the drain chambers provided adjacent to the collection chamber, depending on the flow behavior of the processing fluid. For fluidic coupling of

Collection chambers with the drainage chambers can be aligned with the

Passage openings of the process chamber openings may be provided, via which the profile sections of the process chamber are supplied or removed on the one hand and, on the other hand, the processing fluid passes from the collection chamber into the drain chambers. As a result of the cascade-like design of the collecting chambers and the drainage chambers, a loss of machining fluid can be prevented and a high level of efficiency can be achieved in the operation of the profile-machining device.

As part of the profile processing device can in particular a

Be provided for the processing fluid circulation conveyor. As part of the circulation conveyor may include a reservoir for the machining fluid, a pump unit for conveying the machining fluid from the reservoir to the fluid supply unit and various piping for connecting the collection chamber or the drain chamber with the reservoir and the Fluidzuführeinheit be provided. For example, a diaphragm pump may be provided as part of the pump unit, which provides a pressure fluctuation corresponding to a pump speed. The pressure fluctuation may favor, for example, the cleaning effect.

In order to process in particular a tubular jacket surface, the process chamber may have a circular inner cross-sectional geometry. Provided so far, for example, that by means of a specifically trained

Profile processing device Tubes with an outside diameter of 8 mm to 30 mm can be machined. A cross-sectional geometry of the process chamber is so far on the largest profile diameter, that is designed on the Au ßendurchmesser of 30 mm. The process chamber has so far, for example, an inner diameter of 33 mm. Depending on the diameter of the pipes to be machined, the pipes more or less fill the process chamber. So far, at a

Pipe diameter of 30 mm and a circular cross-section of

Process chamber of 33 mm comparatively little processing fluid

While processing of pipes with an outer diameter of 10 mm, the processing fluid must be supplied in large quantities. Again, the provision of a Fluidzuführeinheit with variable flow rate or switchable ring feeders is advantageous.

For example, can be provided to support the cleaning effect that cleaning fluid in the process chamber to induce vibrations, for example, to ultrasonic vibrations. The vibration excitation can take place, for example, via an excitation of the housing of the process chamber to oscillations.

On the output side, a post-processing module may be provided adjacent to the collection chamber or the at least one discharge chamber for post-processing of the profile section processed in the process chamber. For this purpose, the post-processing module has, in particular, a fluid nozzle which is positioned and designed such that a post-processing fluid having individual process parameters can be applied to the profile section. For example, the fluid nozzle of the post-processing module may be designed in the manner of an annular nozzle such that a fluid flow flows along a surface of the profile section. This can be advantageous in particular in the coating of profiles the Coating be formed uniformly and in the required thickness. The use of the annular nozzle is advantageous in this case because, with a small amount of the post-processing fluid, large quantities of air can be sucked in through the nozzle effect and the volumetric flow of the fluid conducted over the surface can be increased. By the flow along the profile lateral surface, for example, a uniform coating thickness can be promoted. For example, as

Fluid nozzle provided a radiating nozzle, which in terms of their

Cross-sectional geometry is shaped so that the post-processing module accelerated in the Abstrahldüse and is emitted in the direction of the profile section. By providing the Abstrahldüse example, adhesions to the

Profile section to be removed. A cleaning of the profile section is favored in this way.

From the other dependent claims and the following description further advantages, features and details of the invention can be found. There mentioned features may be essential to the invention individually or in any combination. The drawings are merely exemplary of the

Clarification of the invention and have no limiting character. Show it:

Fig. 1 is a schematic representation of an inventive

Profile processing device with an elongated process chamber, the process chamber frontally associated collection chambers and a respective drain chamber and a

Post-processing module, which is used to machine a pipe section with a small diameter,

Fig. 3, the profile processing apparatus of FIG. 1, which for processing a

Tube profile is used with a large outer diameter,

Fig. 4, the profile machining apparatus of FIG. 1 with a modified

Post-processing module, which provides a radiating nozzle, and Fig. 5 shows an alternative embodiment of the profile machining device according to the invention.

A profile-machining device according to FIGS. 1 and 3 has as essential components an elongated process chamber 1, with a plurality of feed openings 2 provided on the casing side on the process chamber 1 and with end-side passage openings 4, 5 for feeding a profile section to the process chamber 1, one of the process chamber 1 assigned on the shell side

Fluidzuführeinheit 6, two of the process chamber 1 frontally in the field of

Passage openings 4, 5 associated collecting chambers 7, 8 and adjacent to the collecting chambers 7, 8 provided drain chambers 9, 10 before. The process chamber 1 is formed elongated in a longitudinal direction 3. A length L of

Process chamber 1 is more than ten times as large as an internal transverse dimension Q of the process chamber 1. In the present case, the process chamber 1 is circular in cross section.

Centered on the passage openings 4, 5 of the process chamber 1 is the

Fluid supply unit 6 assigned. In the present case, the fluid supply unit sees a centric ring feed 11 and, adjacent thereto, two more on both sides

Ring feeders 12 before. A cross-section through the ring feed 1 1 of FIG. 2 shows the shell side distributed in the circumferential direction of the process chamber 1 arranged feed openings 2. In the same way, the other ring feeders 12 are associated with the other feed openings 3. The ring feed 1 1 and the further ring feed 12 surround the process chamber 1 on the shell side insofar as they are assigned in the circumferential direction of the shell side of the process chamber 1. In order to vary the amount of processing fluid introduced into the process chamber 1, the ring feed 11 and the further ring feed 12 can be individually switched on or off. In this respect, depending on the geometry of the profile section 50 and the processing routine, a small or a large amount of processing fluid can be introduced into the process chamber 1.

For example, in the coating of the profile, a large volume flow of the machining fluid is introduced into the process chamber 1 at a low pressure of approximately 1 bar. The profile section 50 is preferably completely surrounded by the jacket side. The machining fluid then exits the process chamber 1 via the passage openings 4, 5 on the face side and is collected in the collection chambers 7, 8. At the collection chambers 7, 8 are insofar drain holes 13 provided for the machining fluid. Further, an opening 14 is provided between the collecting chambers 7, 8 and the discharge chambers 9, 10. About the breakthrough 14 passes

Processing fluid from the collection chamber 7, 8 in the associated discharge chamber 9, 10, as soon as a corresponding liquid level is reached. This can

For example, the case when the amount of the supplied processing fluid can not be removed via the drain holes 12 of the collecting chambers 7, 8 alone. The discharge chamber 9, 10 is insofar associated with a further discharge opening 15 for discharging the processing fluid from the discharge chamber 9, 10.

Not shown is that as part of the profile processing device

Circulation conveyor for the machining fluid is provided with a processing fluid, not shown, with a pump unit for conveying the machining fluid from the reservoir to the Fluidzuführeinheit 6 and with pipes through which the machining fluid enters the reservoir or is conveyed from the reservoir to Fluidzuführeinheit 6. The processing fluid is thus pumped in the circulation and reused.

As shown comparatively in Figs. 1 and 3, in the same

Post-processing device with the same process chamber 1 pipe sections 50, 60 are processed with different diameters. The passage openings 4, 5 of the process chamber 1 and the openings 14 are so far adapted to the largest pipe diameter of the pipe section 60 and thus equally suitable to accommodate pipe sections 50 with smaller outer diameter.

In the coating of profile sections 50, 60, all fluids conventionally used for decorative or protective coatings, in particular water-based paints, lacquers or corrosion inhibitors, come into consideration as machining fluids. At the

In particular, oils or greases can be used to clean the profile sections.

As part of the profile processing device according to the embodiment of FIGS. 1 and 3, a post-processing module 16 is provided with an annular nozzle 17. The

Ring nozzle 17 serves to form a coating applied to the pipe section 50, 60 uniformly and in a predetermined thickness. For this purpose, a post-processing fluid of the annular nozzle 17 is fed via a feed opening 18. With the Post-processing fluid is sucked in air and an air flow along the surface of the tube section 50, 60 is provided which uniformly distributes the processing fluid applied to the coating and selectively influences a thickness of the coating depending on the process parameters. For example, via the annular nozzle 17 of the post-processing module heated or hot compressed air as

Post-processing fluid are supplied, so that there is a good drying effect. For example, nitrogen can be supplied as a post-processing fluid via the annular nozzle 17.

According to the exemplary embodiment according to FIG. 4, the post-processing module 16 provides a plurality of emission nozzles 19. About the radiating nozzles 19 is the

Post-processing fluid pressure applied to the pipe section 60. In this case, the post-processing fluid serves to additionally clean the tube section 60. For example, the ejection nozzles 19 are designed in the manner of Laval nozzles. About a drain opening 20, the post-processing fluid passes from the

Post-processing module 16 and is carried away. For example, a circulation conveyor for the post-processing fluid can also be provided here.

According to an alternative embodiment of the invention shown in FIG. 5 is the

Process chamber 1 with the opposite passage openings 4, 5 enclosed by a single collection chamber 7. In the present case, the process chamber 1 is held on a cover of the collection chamber 7. At the collecting chamber 7 a Zuführausnehmung 21 for the profile section 50 and a discharge recess 22 for the profile section 50 are provided. The processing fluid supplied via the fluid supply unit 6 or the annular supply line 1 1, 12 which is embodied as a part thereof emerges via the passage openings 4, 5 from the process chamber 1 and is collected in the collection chamber 7.
