Definitions
- the invention relates to a device for the production of transverse finned tubes, with mold jaw halves, which are moved circumferentially along two endless guideways adjacent to one another by means of an associated drive device, the two guideways having a common molding path, a return path and two deflection paths, the respective deflection path has a deflecting member with an arcuate guide edge.
- a device for the production of transverse finned tubes which has a linear guide device along the common molding section for guiding the mold jaw halves, said linear guide device comprising an elongated central sliding body, preferably made of a sliding metal alloy, and two oil-lubricated provided laterally next to the sliding body Guide bodies, preferably made of an abrasion-resistant metal.
- the guideways along the common molding section and along the two return sections have elongated wear elements made of a low-wear plastic material, which are provided interchangeably on a base device of the device.
- the elongated wear elements made of the low-wear plastic material are provided on the base device of the device according to the invention in such a way that, if necessary, i.e. after a long service life of the device and a corresponding wear, i.e. a corresponding wear of the
- Wear parts can be exchanged easily and in a time-saving manner and can be replaced by unused new plastic wear parts.
- the elongated wear elements made of wear-resistant plastic material are preferably provided resiliently on the base device.
- the elongated wear elements preferably consist of a low-wear plastic material. It has proven to be particularly advantageous if a plastic material with oil deposits is used for the wear elements because this minimizes the friction between the wear elements and the mold jaw halves and consequently increases the productivity of the device accordingly.
- the elongated wear elements are expediently formed with two longitudinal slots, which are provided laterally spaced apart from one another in parallel and which are provided congruently with a cooling medium inlet and with a cooling medium outlet of the mold jaw halves.
- the cooling medium inlet and the cooling medium outlet of the respective mold jaw half are expediently designed such as is described in patent application 10257363.8 " , which in this respect belongs to the disclosure content of the present application.
- the deflection members provided between the common molding section and the two return sections consist of a low-wear plastic material, which is preferably also a plastic material with oil deposits.
- the deflecting members of the device according to the invention are preferably each connected to a compensation device, by means of which a temperature and / or speed-dependent tolerance play of the mold jaw halves running along the respectively associated guideway is compensated for.
- FIG. 1 cut off an embodiment of the device in the viewing direction from above
- Figure 2 is a view of two mold jaw halves on the common molding line in the direction of arrows II-II in Figure 1, and
- Figure 3 is a perspective view of a deflection path of the device, wherein a mold jaw half is shown cut off.
- FIG. 1 shows a device 10 for the production of transverse finned tubes cut away from above.
- the device 10 has a base device 12 with two endless guideways 14 for mold jaw halves 16, of which only two mold jaw halves 16 are shown in FIG. 1.
- the two guideways 14 have a common molding section 18, in each case a return section 20 running parallel to the common molding section 18 and in each case two deflection sections 22 and 24.
- Deflection members 26 are provided on the deflection sections 22 and deflection members 28 are provided on the deflection sections 24.
- Elongated wear elements 30 are provided along the common molding section 18 and along the return sections 20.
- the elongated wear elements 30 are provided on the base device 12 in a simple and time-saving interchangeable manner.
- the elongated wear elements 30 consist of a low-wear plastic material with oil deposits.
- the elongated wear elements 30 are resiliently provided on the base device 12. This is indicated schematically in FIG. 2 by the double arrows 32.
- FIG. 2 also illustrates that the elongated wear elements 30 are each formed with two longitudinal slots 34 and 36.
- the longitudinal slots 34 and 36 are spaced apart from one another and run parallel to one another.
- the mold jaw halves 16, which form a molding channel 38 for the transverse finned tube to be produced along the common molding path 18, are each formed with a cooling channel 40 with a cooling medium inlet 42 and with a cooling medium outlet 44.
- the respective coolant inlet 42 is congruent with the associated longitudinal slot 34.
- the respective coolant outlet 44 is congruent with the associated longitudinal slot 36.
- the cooling medium inlet 42 and the cooling medium outlet 44 are preferably designed in such a way as is described in the patent application 10257363.8.
- the respective deflection member 26, 28 is detachably attached to a displacement element 46 which is arranged on a base element 48 so as to be linearly movable.
- the base element 48 is provided in a machine-fixed manner.
- a compensation device 50 which is described as an air spring 52 (see FIGS. 1 and 3), is connected to the displacement element 46.
- a compensation device or air spring is described, for example, in the Festo brochure "Fluidic Muscle Type MAS ".
- the air spring 52 has two connection fittings 54 and 56.
- the connection spring 54 connects the air spring 52 to the displacement element 46
- the connection fitting 56 is connected to a machine-fixed bracket 58 (see FIG. 1) and is provided with a compressed air connection.
- the compensation devices 50 with the air springs 52 serve to compensate for a temperature- and / or speed-dependent tolerance play of the mold jaw halves 16 which are adjacent and abut along the associated guideway 14, so that there is a smooth transition between the rectilinear return path 20 and the deflection paths 22, 24 and between the U steering sections 22 and 24 and the common straight line Form section 18 results.
- the device 10 can consequently be operated with a correspondingly high operating speed and high productivity.
