Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Bearbeiten der Aufsetzfläche eines eine Negativform für ein Schachtbodengerinne bildenden, gegebenenfalls aus Profilstücken zusammengesetzten Formprofils aus thermoplastischem Schaumstoff, das mit einer Bearbeitungszugabe im Bereich der Aufsetzfläche versehen ist, mit einem Tisch zur Aufnahme des zu bearbeitenden Formprofils und mit einem entsprechend dem Querschnittprofil der herzustellenden Aufsetzfläche verlaufenden Heizdraht, der relativ zum Tisch entlang der zu bearbeitenden Aufsetzfläche bewegbar ist.The invention relates to a device for processing the contact surface of a negative mold for a manhole bottom forming, optionally composed of profile pieces mold profile made of thermoplastic foam, which is provided with a machining allowance in the landing area, with a table for receiving the mold profile to be machined and a heating wire extending according to the cross-sectional profile of the contact surface to be produced, which is movable relative to the table along the contact surface to be machined.

Da die Gerinne von Schächten im allgemeinen an die örtlichen Gegebenheiten einer Baustelle anzupassen sind, werden die Schachtböden häufig mit einem Rohboden ohne Gerinne in einer aus einem topfartigen Kern und einem Mantel bestehenden Form gefertigt, so daß das Gerinne nachträglich entsprechend der jeweiligen Abwasserkanalführung von Hand aus geformt werden kann. Zur Vermeidung der mit einer solchen Handfertigung verbundenen Nachteile können zumindest die in das Hauptgerinne mündenden, üblicherweise gerade verlaufenden Gerinneäste mit Hilfe von Profilstükken gefertigt werden, die als Negativform des Gerinneastes am Boden des Formkemes befestigt werden und an den durch den Formkern gebildeten Profilstrang für das Hauptgerinne anschließen. Dabei ergeben sich besonders einfache Konstruktionsverhältnisse, wenn der Profilstrang für das Hauptgerinne aus geraden und kreisbogenförmigen Abschnitten zusammengesetzt ist und ebenfalls auf dem Boden des Formkernes befestigt wird, weil in diesem Fall auch der Profilstrang für das Hauptgerinne den örtlichen Gegebenheiten angeglichen werden kann. Es muß allerdings dafür gesorgt werden, daß die stirnseitigen Anschlußflächen der Profilstücke für die Gerinneäste entsprechend dem Profilquerschnitt und dem Achsverlauf des Profilstranges für das Hauptgerinne bearbeitet werden, was wegen der geforderten unterschiedlichen Krümmungen dieser Anschlußflächen unter Umständen mit einem erheblichen Bearbeitungsaufwand verbunden ist. Zur Vermeidung dieses Arbeitsaufwandes wurde bereits vorgeschlagen, die Profilstücke für die Gerinneäste aus einem thermoplastischen Kunststoff zu fertigen, um die Anschlußflächen dieser Profilstücke mit einem entsprechend dem Umrißverlauf des Profilstranges für das Hauptgerinne geformten Heizdraht zu schneiden, der entlang einer mit dem Achsverlauf des Profilstranges für das Hauptgerinne übereinstimmenden Bahn gegenüber dem ausgerichteten Profilstück bewegt wird, wobei darauf zu achten ist, daß die Ebene des Heizdrahtes stets senkrecht zum Achsverlauf des Profilstranges für das Hauptgerinne ausgerichtet ist. In diesem Fall überstreicht der Heizdraht eine Hüllfläche, die der Oberfläche des Profilstranges im Anschlußbereich des Gerinneastes entspricht. Das Formprofil für das Schachtbodengerinne kann daher vergleichsweise einfach durch einen Profilstrang für das Hauptgerinne und an diesen Profilstrang formschlüssig anschließende Profilstücke für die Gerinneäste zusammengesetzt werden. Der das in dieser Weise vorbereitete Formprofil für das Schachtbodengerinne aufnehmende Boden des Formkemes, der die spätere Auftrittfläche des Schachtbodens bildet, weist zu diesem Zweck eine ebene Aufsetzfläche für das Formprofil auf, die gegebenenfalls gegen den Gerinneablauf hin abfällt. Solche ebene Auftrittflächen des Schachtbodens bringen allerdings die Gefahr mit sich, daß Abwasserrückstände auf der Auftrittfläche nicht zum Schachtbodengerinne hin abfließen. Aus diesem Grunde werden die Auftrittflächen von Schachtböden kegelförmig ausgebildet, so daß Abwasserrückstände gegen die Bodenmitte hin zum Gerinne abfließen. Zur Ausbildung solcher kegelförmiger Auftrittflächen braucht lediglich der Formkem mit einem entsprechend kegelförmigen Boden versehen zu werden. Ein kegelförmiger Kemboden bringt allerdings Schwierigkeiten mit sich, wenn ein die Negativform des späteren Gerinnes ergebendes Formprofil formschlüssig auf den Boden des Formkems aufgesetzt werden soll.Since the channels of manholes are generally adapted to the local conditions of a construction site, the manhole bottoms are often made with a rough bottom without flume in an existing cup-like core and a shell shape, so that the flume subsequently according to the particular sewer guide by hand can be shaped. In order to avoid the disadvantages associated with such handcrafting, at least the gutter branches opening into the main gutter can be made by means of profile pieces which are attached to the bottom of the molding core as negative molds of the guttering and to the profile strand formed by the mandrel for the main gutter connect. This results in particularly simple construction conditions, when the profile strand for the main channel of straight and circular arc Assembled sections and is also attached to the bottom of the mandrel, because in this case, the profile strand for the main channel can be adapted to local conditions. However, it must be ensured that the frontal pads of the profile pieces for the gutter branches are processed according to the profile cross-section and the axis of the profile strand for the main gutter, which may be due to the required different curvatures of these pads under certain circumstances associated with a considerable amount of processing. To avoid this workload has already been proposed to produce the profile pieces for the gutter branches of a thermoplastic material to cut the pads of these profile pieces with a corresponding contour contour of the profile strand for the main channel shaped heating wire along a with the axis of the profile strand for the Main chute coinciding path is moved relative to the aligned profile piece, wherein it should be ensured that the plane of the heating wire is always aligned perpendicular to the axis of the profile strand for the main chute. In this case, the heating wire covers an envelope surface, which corresponds to the surface of the profile strand in the connection region of the Gerinneastes. The shape profile for the shaft floor channel can therefore be relatively easily assembled by a profile strand for the main channel and this profiled strand form-fitting subsequent profile pieces for the channel branches. The prepared in this way shape profile for the manhole bottom receiving bottom of the mold core, which forms the subsequent occurrence surface of the shaft bottom, has for this purpose a flat contact surface for the mold profile, which optionally drops against the channel flow out. However, such flat landing surfaces of the shaft bottom entail the risk that wastewater residues on the tread surface will not flow off to the bottom of the shaft. For this reason, the tread surfaces of shaft bottoms are cone-shaped, so that wastewater residues flow towards the bottom towards the gutter. To form such conical contact surfaces only the Formkem needs to be provided with a corresponding conical bottom. However, a conical Kemboden brings difficulties when a negative profile of the subsequent channel resulting profile shape to be placed positively on the bottom of the mold.

Zur Bearbeitung von thermoplastischen Schaumstoffblöcken ist es bereits bekannt ( FR 2 754 208 ), einen in einem Bügel eingespannten Heizdraht vorzusehen, der um drei zueinander senkrechte Achsen auf einem Arm eines Roboters drehbar gelagert ist. Da der Roboterarm selbst um eine horizontale Achse verschwenkbar ist und mit dem Gestell des Roboters um eine vertikale Achse gedreht werden kann, kann der Heizdraht in einer beliebigen Raumlage gehalten werden. Mit Hilfe eines auf solche Art geführten Heizdrahtes läßt sich somit ein auf einem Drehtisch abgestützter thermoplastischer Schaumstoffblock zu einem Rotationskörper mit einem aus geraden Erzeugenden gebildeten Mantel und folglich auch in Kegelform bearbeiten, allerdings nicht zu einem Werkstück mit einer kegelförmigen Aussparung.For processing of thermoplastic foam blocks it is already known ( FR 2 754 208 ) to provide a clamped in a bracket heating wire which is rotatably mounted about three mutually perpendicular axes on an arm of a robot. Since the robot arm itself is pivotable about a horizontal axis and can be rotated with the frame of the robot about a vertical axis, the heating wire can be kept in any spatial position. With the help of a guided in such a type of heating wire thus supported on a turntable thermoplastic foam block can be processed to a rotating body with a jacket formed from straight generatrix and consequently also in the form of cones, but not to a workpiece with a conical recess.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Vorrichtung zum Bearbeiten der Aufsetzfläche eines Formprofils aus thermoplastischem Schaumstoff der eingangs geschilderten Art so auszugestalten, daß mit einfachen Mitteln eine der kegelförmigen Bodenfläche des Formkerns entsprechende Aufsetzfläche des Formprofils erhalten wird.The invention is therefore based on the object, a device for processing the contact surface of a molded profile made of thermoplastic foam of the type described in such a way that with simple means of a conical bottom surface of the mandrel corresponding contact surface of the mold profile is obtained.

Die Erfindung löst die gestellte Aufgabe dadurch, daß der das Formprofil koaxial zur Aufsetzfläche aufnehmende Tisch um die Aufnahmeachse relativ zum Heizdraht drehbar ist, der ausgehend von einer Abstützung in der Aufnahmeachse unter einem der zu bearbeitenden kegelförmigen Aufsetzfläche entsprechenden Winkel gegenüber der Aufnahmeachse geneigt verläuft, und daß der Tisch einen Durchtritt für den relativ zum Tisch in Richtung der Aufnahmeachse in die Bearbeitungszugabe des Formprofils einstechenden Heizdraht aufweist.The invention solves the problem set by the fact that the mold profile coaxial with the seating surface receiving table is rotatable about the receiving axis relative to the heating wire, which extends starting from a support in the receiving axis at one of the machined tapered contact surface corresponding angle to the receiving axis, and that the table has a passage for the relative to the table in the direction of the receiving axis in the machining allowance of the mold profile piercing heating wire.

Da eine Kegelfläche gerade Erzeugende aufweist, kann eine solche Kegelfläche durch einen gerade verlaufenden Heizdraht bearbeitet werden, der um die Achse der Kegelfläche relativ zum Werkstück aus thermoplastischem Schaumstoff gedreht wird. Bei den zu bearbeitenden Formprofilen ergibt sich allerdings die Schwierigkeit, daß diese Formprofile nur mit ihrer Aufsetzfläche lagegenau von einem Tisch aufgenommen werden können, so daß die zu bearbeitende Fläche nicht frei zugänglich ist. Aus diesem Grunde ist der Tisch mit einem Durchtritt für den relativ zum Tisch in Richtung der mit der Kegelachse übereinstimmenden Aufnahmeachse des Formprofils verlagerbaren Heizdraht versehen, der somit vor der Bearbeitung der Aufsetzfläche durch eine Relativbewegung des Heizdrahtes gegenüber dem Tisch in Richtung der Aufnahmeachse in die Bearbeitungszugabe des Formprofils einstechen muß, um eine vorgegebene Ausgangslage für die eigentliche Bearbeitung der Aufsetzfläche zu erreichen. Da aufgrund des Schmelzvorganges während der Relativdrehung des Heizdrahtes gegenüber dem Formprofil nur geringe Umfangskräfte auf das Formprofil ausgeübt werden, bedarf es keiner gesonderten Halterung des Formprofils während der Bearbeitung der Aufsetzfläche. Es ist lediglich darauf zu achten, daß das Formprofil gegenüber der Drehachse des Tisches ausgerichtet auf den Tisch aufgebracht wird, so daß die Aufnahmeachse koaxial zur Drehachse der Aufsetzfläche verläuft.Since a conical surface has straight generatrices, such a conical surface can be machined by a straight filament that is rotated about the axis of the conical surface relative to the thermoplastic foam workpiece. In the case of the molded profiles to be machined, however, there is the difficulty that these shape profiles can be recorded with a precise position of a table only with their contact surface, so that the surface to be machined is not freely accessible. For this reason, the table is provided with a passage for the relative to the table in the direction of the conical axis coinciding with the receiving axis of the mold profile displaceable heating wire, thus, before the processing of the contact surface by a relative movement of the heating wire relative to the table in the direction of the recording axis in the machining allowance of the mold profile must penetrate to achieve a predetermined starting position for the actual processing of the contact surface. Since due to the melting process during the relative rotation of the heating wire relative to the mold profile only small circumferential forces are exerted on the mold profile, it requires no separate support of the mold profile during processing of the contact surface. It is only necessary to ensure that the mold profile is aligned with respect to the axis of rotation of the table on the table, so that the receiving axis is coaxial with the axis of rotation of the contact surface.

Obwohl es lediglich auf eine Relativdrehung zwischen dem Tisch und dem Heizdraht ankommt, ergeben sich besonders einfache Konstruktionsverhältnisse, wenn der Tisch gegenüber dem drehfest gehaltenen Heizdraht drehbar in einem Gestell gelagert wird, weil in diesem Fall keine Vorkehrungen getroffen werden müssen, einem drehenden Teil Strom zuzuführen. Ähnliche Vorteile ergeben sich, wenn der Tisch gegenüber dem Heizdraht im Gestell über eine Hubeinrichtung in Richtung der Aufnahmeachse der Höhe nach verstellt wird, weil wiederum der Heizdraht gestellfest angeordnet werden kann.Although it depends only on a relative rotation between the table and the heating wire, particularly simple construction conditions arise when the table is rotatably supported in a frame relative to the rotatably held heating wire, because in this case no precautions must be taken to supply power to a rotating part , Similar advantages arise when the table relative to the heating wire in the frame via a lifting device in the direction of the receiving axis of the height is adjusted, because in turn the heating wire can be arranged fixed to the frame.

Um die Bearbeitung der Aufsetzfläche des Formprofils in einer vergleichsweise kurzen Bearbeitungszeit vornehmen zu können, kann der Heizdraht auf einander diametral gegenüberliegenden Seiten der Aufnahmeachse zwei zur Aufnahmeachse symmetrische Äste aufweisen, so daß eine Relativdrehung von 180° für eine vollständige Bearbeitung der Aufsetzfläche ausreicht. Der Heizdraht kann dabei in einfacher Weise über einen zur Aufnahmeachse koaxialen Dorn abgestützt werden, wobei sich besonders einfache elektrische Anschlußbedingungen ergeben, weil ja die Heizdrahtenden frei zugänglich sind. Im allgemeinen reicht die Heizleistung des über den Dorn geführten Heizdrahtes aus, um den Einstich des Heizdrahtes in die Bearbeitungszugabe des Formprofils auch im Bereich der Domabstützung sicherzustellen. Wird ein größerer Eindringwiderstand des Dorns im Bereich der durch den Heizdraht geschmolzenen Trennfuge befürchtet, so kann zusätzlich die Spitze des Doms zur Abstützung des Heizdrahtes mit einem quer zum Heizdraht verlaufenden Heizdrahtbügel umschlossen werden, der für eine Erweiterung der Trennfuge im Bereich des Doms sorgt. Zur Einstellung des Kegelwinkels der Auftrittfläche des Schachtbodens kann schließlich der Dorn in Richtung der Aufnahmeachse verstellt werden, so daß sich mit der Verstellung des Doms der Neigungswinkel der Heizdrahtäste übereinstimmend verändert.In order to make the machining of the contact surface of the mold profile in a relatively short processing time, the heating wire on diametrically opposite sides of the receiving axis may have two branches symmetrical to the receiving axis, so that a relative rotation of 180 ° sufficient for a complete processing of the contact surface. The heating wire can be supported in a simple manner via a mandrel coaxial with the receiving axis, which results in particularly simple electrical connection conditions, because yes the Heizdrahtenden are freely accessible. In general, the heating power of the guided over the mandrel heating wire is sufficient to ensure the puncture of the heating wire in the machining allowance of the mold profile in the Domausstützung. If a greater penetration resistance of the mandrel in the region of the parting line melted by the heating wire is feared, then additionally the tip of the mandrel for supporting the heating wire can be enclosed by a heating wire bow extending transversely to the heating wire, which provides for expansion of the parting line in the area of the mandrel. To adjust the cone angle of the tread surface of the shaft bottom, the mandrel can finally be adjusted in the direction of the receiving axis, so that coincides with the adjustment of the dome of the inclination angle of Heizdrahtäste changed.

Im allgemeinen liegen die Gerinneabläufe tiefer als die Gerinnezuläufe. Dies kann durch eine entsprechende Neigung der Kegelachse der Auftrittfläche gegen den Gerinneablauf berücksichtigt werden. Eine solche zusätzlich geneigte Auftrittfläche des Schachtbodens bedingt eine entsprechend geneigte, kegelförmige Bodenfläche des Formkems, was wiederum eine Anpassung der Aufsetzfläche des Formprofils nach sich zieht. Zu diesem Zweck kann der Tisch um eine Querachse zur Aufnahmeachse schwenkverstellbar gelagert werden, so daß über die Schwenkverstellung des Tisches die zusätzliche Neigung der kegelförmigen Auftrittfläche des Schachtbodens nachgebildet werden kann. Aufgrund der Neigung der Aufnahmeachse stimmt allerdings die Aufnahmeachse nicht mehr mit der Drehachse des Tisches überein.Generally, the channels are deeper than the channels. This can be taken into account by a corresponding inclination of the cone axis of the tread surface against the channel course. Such an additionally inclined contact surface of the shaft bottom requires a correspondingly inclined, conical bottom surface of the shaped core, which in turn results in an adaptation of the contact surface of the molded profile. For this purpose, the table may be about a transverse axis to the receiving axis are mounted pivotally adjustable so that the additional inclination of the conical surface of the shaft bottom can be simulated on the pivoting adjustment of the table. Due to the inclination of the recording axis, however, the recording axis is no longer consistent with the axis of rotation of the table.

Damit das Formprofil an den Durchmesser des zylindrischen Formkerns angepaßt werden kann, kann durch wenigstens einen zusätzlichen, parallel zur Aufnahmeachse verlaufenden Heizdraht, der in einem radial zur Aufnahmeachse an den Tisch anstellbaren und relativ zum Tisch um die Aufnahmeachse drehbar gelagerten Träger gehalten ist, dafür gesorgt werden, daß die äußeren Stirnseiten des Formprofils in einer dem Durchmesser des Formkems entsprechenden zylindrischen Hüllfläche liegen. Ist ein Heizdraht mit auf einander diametral gegenüberliegenden Seiten der Aufnahmeachse liegenden Ästen für die Bearbeitung der Aufsetzfläche vorgesehen, so empfiehlt es sich, zwei einander ebenfalls diametral bezüglich der Aufnahmeachse gegenüberliegende Heizdrähte vorzusehen, um mit einem halben Tischumlauf eine vollständige Bearbeitung des Formprofils zu erreichen.So that the shape profile can be adapted to the diameter of the cylindrical mandrel can, by at least one additional, parallel to the receiving axis heating wire, which is held in a radially engageable to the receiving axis to the table and rotatable relative to the table about the receiving axis carrier provided be that the outer end faces of the mold profile lie in a diameter corresponding to the diameter of the shaped cylindrical surface. If a heating wire provided with diametrically opposite sides of the receiving axis branches for processing the contact surface, it is advisable to provide two diametrically opposite each other with respect to the receiving axis heating wires to achieve half a table circulation complete processing of the mold profile.

Die dargestellte Vorrichtung zum Bearbeiten der Aufsetzfläche 1 eines Formprofils 2 aus thermoplastischem Schaumstoff als Negativform für ein Schachtbodengerinne weist ein Gestell 3 auf, das einen Aufnahmetisch 4 trägt. Dieser Aufnahmetisch 4 ist auf einem Drehkranz 5 gelagert, der über eine Tragplatte 6 auf Führungsschlitten 7 aufruht. Die Tragplatte 6 kann daher mit Hilfe einer beispielsweise aus Hubzylindern bestehenden Hubeinrichtung 8 entlang von Führungen 9 für die Schlitten 7 der Höhe nach verstellt werden. Zum Antrieb des Drehkranzes 5 dient ein den Drehkranz 5 außen umfassender Zahnriementrieb 10, dessen Antrieb mit 11 bezeichnet ist.The device shown for processing the contact surface 1 of a molded profile 2 made of thermoplastic foam as a negative mold for a shaft bottom channel has a frame 3, which carries a receiving table 4. This shooting table 4 is mounted on a turntable 5, which rests on a support plate 6 on guide carriage 7. The support plate 6 can therefore be adjusted by means of an example of lifting cylinders existing lifting device 8 along guides 9 for the carriage 7 in height. To drive the turntable 5 is a turntable 5 outside comprehensive toothed belt drive 10, whose drive is designated 11.

Der Tisch 4 zur Aufnahme des Formprofils 2 ist gegenüber dem Drehkranz 5 um eine Querachse 12 verschwenkbar gelagert. Zu diesem Zweck trägt der Drehkranz 5 zwei Seitenwangen 13, an denen der Tisch 4 über die Schwenkachse 12 angelenkt ist, und zwar mit Hilfe von die Seitenwangen 13 umgreifenden Stegen 14. An den der Schwenkachse 12 gegenüberliegenden Enden sind die Stege 14 durch eine Achse 15 miteinander verbunden, an der ein zwischen den Seitenwangen 13 angeordneter Schwenkantrieb 16 angreift. Wie insbesondere der Fig. 4 entnommen werden kann, kann somit der Tisch 4 durch eine Betätigung des Schwenkantriebes 16, beispielsweise in Form eines Spindeltriebes, in seiner Neigung verstellt werden.The table 4 for receiving the mold profile 2 is mounted pivotably relative to the turntable 5 about a transverse axis 12. For this purpose, the turntable 5 carries two side cheeks 13, on which the table 4 is articulated about the pivot axis 12, with the help of the side cheeks 13 encompassing webs 14. At the pivot axis 12 opposite ends of the webs 14 through an axis 15th connected to each other, on which a arranged between the side walls 13 pivot drive 16 engages. How the particular Fig. 4 can be removed, thus the table 4 can be adjusted in its inclination by an actuation of the pivot drive 16, for example in the form of a spindle drive.

An einander bezüglich der Achse des Drehkranzes 5 diametral gegenüberliegenden Seiten des Gestells 3 sind Ausleger 17 zur Abspannung eines Heizdrahtes 18 vorgesehen, der zwischen den endseitigen Halterungen 19 auf einem zum Drehkranz 5 koaxialen Dorn 20 abgestützt ist und zwei zum Dorn 20 symmetrische Äste 21 bildet, die sich in der Achse des Drehkranzes 5 schneiden. Der Dorn 20 ist auf einem Halter 22 angeordnet, der auf einem gestellfesten Träger 23 befestigt ist und die Tragplatte 6 sowie den Drehkranz 5 in einer mittigen Öffnung durchsetzt. Zur Einstellung der Neigung der Heizdrahtäste 21 kann der Dorn 20 mit dem Halter 22 auf dem Gestell 3 in Richtung der Achse des Drehkranzes 5 verstellt werden, was jedoch aus Übersichtlichkeitsgründen nicht dargestellt ist. Im Tisch 4 ist ein Durchtritt 24 für den Heizdraht 18 vorgesehen, so daß der Tisch 4 aus der in der Fig. 2 dargestellten Ausgangslage in eine Arbeitslage gemäß der Fig. 3 abgesenkt werden kann, in der der Heizdraht 18 durch den Tisch 4 hindurch in eine Bearbeitungszugabe 25 des Formprofils 2 im Bereich der zu bearbeitenden Aufsetzfläche 1 einstechen kann. In dieser Einstechlage des über die Hubeinrichtung 8 abgesenkten Tisches 4 kann der Drehkranz 5 über den Zahnriementrieb 10 um 180° gedreht werden, wobei die beiden Äste 21 des Heizdrahtes 18 die Bearbeitungszugabe 25 des Formprofils 2 entlang einer Kegelfläche von dem Formprofil 2 abtrennen. Wird demnach das Formprofil 2, das sich aus einem Profilstrang 26 für das Hauptgerinne und einem Profilstück 27 für einen Gerinneast zusammensetzt, so auf die Aufnahme des Tisches 4 aufgesetzt, daß die mit der Drehachse des Drehkranzes 5 übereinstimmende Aufnahmeachse 28 mit der Achse der zu bearbeitenden Aufsetzfläche 1 zusammenfällt, wie dies in der Fig. 2 dargestellt ist, so wird nach dem Einstechen des Heizdrahtes 18 in die Bearbeitungszugabe 25 gemäß der Fig. 3 während der Relativdrehung zwischen dem Heizdraht 18 und dem Formprofil 2 eine Kegelfläche als Aufsetzfläche 1 erhalten, die der Neigung der Äste 21 des Heizdrahtes 18 gegenüber der Aufnahmeachse 28 entspricht.On each other with respect to the axis of the turntable 5 diametrically opposite sides of the frame 3, arms 17 are provided for bracing a heating wire 18, which is supported between the end brackets 19 on a pin 5 coaxial with the turntable 5 and two symmetrical branches 21 forms to the mandrel 20, which intersect in the axis of the turntable 5. The mandrel 20 is arranged on a holder 22 which is mounted on a frame-fixed support 23 and the support plate 6 and the turntable 5 passes through in a central opening. To adjust the inclination of Heizdrahtäste 21, the mandrel 20 can be adjusted with the holder 22 on the frame 3 in the direction of the axis of the turntable 5, but this is not shown for clarity. In the table 4, a passage 24 is provided for the heating wire 18, so that the table 4 from the in the Fig. 2 shown starting position in a working position according to Fig. 3 can be lowered, in which the heating wire 18 through the table 4 can penetrate into a machining allowance 25 of the mold profile 2 in the region of the contact surface 1 to be machined. In this Einstechlage the lowered over the lifting device 8 table 4, the turntable 5 can be rotated by the toothed belt drive 10 by 180 °, wherein the two branches 21 of the heating wire 18, the machining allowance 25 of the mold profile 2 along a conical surface of the mold profile 2 separate. Accordingly, if the mold profile 2, which is composed of a profile strand 26 for the main chute and a profile piece 27 for a Gerinneast, so placed on the receptacle of the table 4, that coincides with the axis of rotation of the turntable 5 receiving axis 28 with the axis to be machined Aufsetzfläche 1 coincides, as shown in the Fig. 2 is shown, so after the insertion of the heating wire 18 in the machining allowance 25 according to the Fig. 3 During the relative rotation between the heating wire 18 and the shape profile 2, a conical surface as a contact surface 1 obtained, which corresponds to the inclination of the branches 21 of the heating wire 18 relative to the receiving axis 28.

Ist zusätzlich eine Neigung der kegelförmigen Auftrittfläche des herzustellenden Schachtbodens zu berücksichtigen, so kann diese Neigung der Auftrittfläche gemäß Fig. 4 durch ein Verschwenken des Tisches 4 um die Schwenkachse 12 eingestellt werden. Mit dieser Verschwenkung des Tisches 4 ergibt sich eine Neigung der Aufnahmeachse 28 gegenüber der Drehachse des Drehkranzes 5, was eine entsprechende Neigung der Achse der kegelförmigen Aufsetzfläche 1 mit sich bringt.If, in addition, an inclination of the conical contact surface of the manhole base to be produced is to be taken into consideration, then this inclination of the landing surface can be taken into account Fig. 4 be adjusted by pivoting the table 4 about the pivot axis 12. With this pivoting of the table 4 results in an inclination of the receiving axis 28 relative to the axis of rotation of the turntable 5, which brings a corresponding inclination of the axis of the conical contact surface 1 with it.

Da die Stege 14, die die beiden durch den Durchtritt 24 voneinander getrennten Aufnahmeteile des Tisches 4 miteinander verbinden, quer zum Heizdraht 18 verlaufen, müssen diese Stege 14 im Bereich des Heizdrahtes eine Auskröpfung 29 aufweisen, damit der Heizdraht 18 auch bei angehobenem Tisch 4 oberhalb der Stege 14 verläuft, wie dies aus der Fig. 2 ersichtlich ist.Since the webs 14, which interconnect the two receiving parts of the table 4 separated from each other by the passage 24, extend transversely to the heating wire 18, these webs 14 must have an offset 29 in the region of the heating wire so that the heating wire 18 is above this even when the table 4 is raised the webs 14 extends, as can be seen from the Fig. 2 is apparent.

Falls der durch den Dorn 20 abgestützte Heizdraht 18 keine ausreichende Trennfuge in die Bearbeitungszugabe 25 des Formprofils 2 schmelzen kann, um den Dorn 20 in diese Schmelzfuge einzuführen, kann gemäß der Fig. 5 die Spitze des Doms 20 zur Abstützung des Heizdrahtes 18 mit einem quer zum Heizdraht verlaufenden Heizdrahtbügel 30 umschlossen werden, der dann so ausgebildet ist, daß das Einstechen des Doms 20 in die Bearbeitungszugabe 25 des Formprofils 2 störungsfrei durchgeführt werden kann.If the heating wire 18 supported by the mandrel 20 can not melt a sufficient parting line into the machining allowance 25 of the shaped section 2 in order to introduce the mandrel 20 into this melting gap, then according to FIG Fig. 5 the tip of the mandrel 20 to support the heating wire 18 are enclosed with a Heizdrahtbügel 30 extending transversely to the heating wire, which is then designed so that the piercing of the mandrel 20 can be performed smoothly in the machining allowance 25 of the mold section 2.

Damit das Formprofil 2 an seinen Stirnflächen entsprechend der Zylinderfläche des Formkerns bearbeitet werden kann, auf dessen Boden das Formprofil zur Herstellung des Schachtbodens aufgebracht wird, können an zwei der Drehachse des Drehkranzes 5 diametral gegenüberliegenden Seiten des Gestells 3 zusätzliche Ausleger 31 mit radial verstellbaren Trägem 32 für parallel zur Drehachse des Tisches 4 verlaufende Heizdrähte 33 vorgesehen sein, so daß mit der Bearbeitung der Aufsetzfläche 1 auch eine Bearbeitung der Stirnflächen der Profilform entlang eines in der Fig. 1 strichpunktiert angedeuteten Hüllzylinders 34 vorgenommen wird.Thus, the shape profile 2 can be machined at its end faces corresponding to the cylindrical surface of the mandrel, on the bottom of the mold profile for the production of the shaft bottom is applied to two of the axis of rotation of the turntable 5 diametrically opposite sides of the frame 3 additional boom 31 with radially adjustable supports 32nd for parallel to the axis of rotation of the table 4 extending heating wires 33 may be provided so that with the processing of the contact surface 1 and a processing of the end faces of the profile shape along a in the Fig. 1 dash-dotted lines indicated enveloping cylinder 34 is made.
