Definitions
- Tubes made of thin-walled sheet metal are usually composed of sections that are to be joined together.
- the type of connection significantly influences the cost-effectiveness of the production and assembly of the sections. This also applies to tubular devices or devices with tubular connections, which are frequently to be integrated into such pipelines, and to tubular devices composed of partial sections.
- connection types a distinction is made between plug-in connections, which are mainly used in smaller-diameter tubes composed of sections, and flange connections. Usually these are
- Flange made separate flanges, which are screwed, riveted, welded or fastened in the same manner at the end of the pipe.
- the flanges are produced by forming the pipe end.
- the simplest type of integrally formed flange is the standing board, which is created by the right-angled edge of the pipe end.
- curls are known, which are generated by the fact that the tube end is rolled into a roughly circular in cross-section bead.
- the connection of these formed as a shelf or rolling flanges clamping rings with U- or V-shaped cross-section, the inside diameter of which is adapted to the cross section of the adjacent flanges serve.
- These clamping rings must have a considerable rigidity, since neither the standing board nor the rolling stiffen the pipe sufficiently in the radial direction at the end. Greater radial rigidity is achieved with such flange flanges, which are formed by two, rectangular, upright edges of the pipe end.
- Such flanges are used - predominantly for device housings, in particular housings of centrifugal fans. These flanges are mainly connected with distributed over the circumference screws.
- the present invention is therefore based on the object, a method and an apparatus for integrally molding a flange at the end of a round or oval tube of thin-walled sheet specified in the preamble of claim 1 type, with which produces a much stronger and much more stable flange can be.
- this object is achieved in that, in a first stage of material accumulation, the end of an axial section of the pipe is formed into a bead while simultaneously feeding a preforming roll tool, followed by a second step to produce a solid section Flange of the bead is compacted with a finished form roller tool.
- the preforming roller tool is advanced so far that an at least single-layer, substantially circular in cross-section bead is formed, which is deformed in the second process stage to a semi-solid flange.
- the preforming roller tool is advanced so far that an at least two-lobed, approximately spiral-shaped bead in cross-section can form in the second process stage, these are compacted into a substantially solid flange.
- the wall of the bead is compressed, thereby producing a higher density flange upon subsequent finish forming.
- a round or oval tube made of thin-walled sheet metal can be produced with an integrally formed, at least partially solid flange which, as stated in claim 10, is dimensioned larger than the wall thickness of the tube and preferably has a rectangular, square, triangular or trapezoidal cross-section with rounded corners.
- a device which has a preforming roller tool for producing the bead, a finished form roller tool for producing the solid flange and a clamping device for the tube.
- the roller tools are in this case non-rotatable, but radially and axially displaceable and the motor risch driven clamping device for the tube rotatable, but arranged axially immovably on a frame.
- the flanged tube is flipped while the roller tools are axially advanced with respect to the tube.
- roller tools are arranged together on a motor-driven, rotatably mounted turntable radially and axially displaceable, while the clamping device is provided for the pipe on the frame axially non-displaceable and non-rotatable.
- the formation of the preform roll tool is specified in claim 14.
- the finished form roller tool is the subject of claim 15.
- a clamping device is suitable, in which according to claim 19 or 20 radially displaceable clamping jaws rest on the inner tube wall frictionally.
- Constructive measures eg B. for actuating the Einspannvor- direction or the drive of the clamping device are characterized with the claims 23 to 25.
- the inventive device for the production of tubes made of sheet metal with integrally formed flanges according to the present invention is particularly suitable for fully automatic production.
- a programmable circuit for controlling the drives, valves and the like aggregates according to predetermined manufacturing processes is necessary.

- flanges 5 to 8 are formed on the tube walls 1 to 4 of a tube, not shown in detail, which are partially solid or fully solid depending on the compression. These flanges can have almost any cross-sectional shapes. Flanges with a trapezoidal cross section 5, 6 or 8, or flanges with a rectangular cross section 7, which are particularly well suited for mounting with clamping rings, are preferred.

- the rollers 19 and 20 have in cross section approximately V-shaped annular grooves, which are bounded by the angularly mutually standing annular surfaces 19a and 19b and 20a and 20b.
- annular surfaces are arranged and dimensioned so that they form in the end position of the forming rollers 19 and 20, as can be seen from Figure 16, a desired cross-section of the flange 5 space and a necessary receiving gap 21 for the pipe wall 1.
- the rollers 19 and 20 are moved together from their position shown in FIG. 13 initially parallel to the tube axis in the direction of the arrow D onto the bead 17 of the tube 11 until the roller 19 with its annular surface 19b the lower edge of the bead 17 touches, as shown in Figure 14. Then the roller 20 obliquely in the direction of the arrow E, ie against the tube wall 1 and the bead 17, moves until it, as Figure 15 shows, with its annular surface 20c, the wall 1 and with its annular surface 20b, the top of the bead 17 touches , The latter is deformed to form the inner inclined surface of the flange. In this position, the roller 20 is locked.

- the distance of the two Anformikien 38 can be adjusted according to the tube length, wherein for inserting and removing the tube 11 at least one Anformtician 38 is to move axially.
- Anformmaschine 42 Another variant for producing a flange to be formed integrally on the tube, which is referred to as an Anformmaschine 42 is illustrated with the figures 21 and 22.
- the tube is stationary during processing, while the roller tools 9 and 18 are mounted on a driven by the geared motor 45 and rotating about the axis of the tube 11 turntable 43.
- the device for clamping the tube 11 is constructed in the same manner as that provided in the apparatus according to FIGS. 18 and 19. Again, the determination of the tube 11 is a clamping plate 31 with clamping jaw segments 34, which are radially displaceable by means of a multiple edge 35, the pull rod 29 and the cylinder 30.
- the base plate 33 carrying the clamping jaw segments 34 is attached to the upper end of the hollow shaft 26 penetrated by the pull rod 29.
