Darüber hinaus betrifft die Erfindung auch ein Verfahren zur Herstellung von Hohlkörpern aus extrudiertem plattenartigen Kunststoffmaterial.The The invention relates to a molding machine for processing extruded rubber, flat plastic material with the features of the preamble of claim 1. In addition The invention also relates to a process for the production of hollow bodies extruded plate-like plastic material.
Eine Formmaschine zur Verarbeitung von flächigem Kunststoffmaterial weist ein Maschinengestell auf, an welchem eine Extrudereinrichtung und eine Formvorrichtung zur tiefziehenden Verformung des extrudierten Kunststoffmaterials angeordnet sind. In der Regel läuft in einer solchen Formmaschine der Herstellungsprozeß des Formteils zweistufig ab, zunächst wird flächiges Kunststoffmaterial hergestellt, die daraus resultierende Platte wird nach Abkühlung und Verfestigung in eine Formvorrichtung eingeführt und dort unter erneuter Erwärmung tiefziehend verformt.A Forming machine for processing flat plastic material has a machine frame, on which an extruder device and a Shaping device for deep-drawing deformation of the extruded plastic material are arranged. Usually runs in such a molding machine, the manufacturing process of the molding in two stages, first becomes areal Plastic material produced, the resulting plate will after cooling and solidification introduced into a molding apparatus and there under again warming deep-drawn deformed.
Ein derartiges zweistufiges Verfahren ist kompliziert und energieaufwändig, darüber hinaus benötigt die Zweistufigkeit des Herstellverfahrens relativ viel Zeit.One Such a two-stage process is complicated and energy consuming, beyond that required Two-stage of the manufacturing process relatively much time.
Der Erfindung liegt die Aufgabe zugrunde, eine Formmaschine mit den Merkmalen des Oberbegriffes des Anspruches 1 derart weiterzubilden, daß Formteile mit weniger Zeit- und Energieaufwand hergestellt werden können. Diese Aufgabe wird hinsichtlich der Formmaschine durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen 2–21.Of the Invention is based on the object, a molding machine with the Further develop features of the preamble of claim 1, that moldings can be produced with less time and energy. These Task is with regard to the molding machine by the characterizing features of claim 1 solved. Advantageous developments emerge from the dependent claims 2-21.
Als Kern der Erfindung wird es angesehen, unter dem Auslaßbereich der mindestens einen Extrudereinrichtung Führungs- und Dichteinrichtungen anzuordnen, die aus mindestens einen vertikal angeordneten Spannrahmen bestehen, in welchen plattenartige Abschnitte des frisch extrudierten Kunststoffmaterials eingebracht werden und dort, d. h. in den Spannrahmen durch ein Formelement der Formvorrichtung verformt werden können. Durch die gegenseitige Anordnung von Extruder und Spannrahmen sowie der Formelemente der Formvorrichtung kann ein gegenüber dem Stand der Technik beschleunigter Verarbeitungsprozeß ablaufen. Die Maschine ist insgesamt kompakt und sehr vielseitig, Formstücke können mit hohen Taktzahlen hergestellt werden. Die Führungs- und Dichteinrichtungen bestehen in vorteilhafter Weise aus parallelen, vertikal angeordneten, zueinander verschiebbaren Spannrahmen, dadurch wird es möglich, innerhalb der Maschine ein Twin-Sheet-Verfahren durchzuführen, bei dem Höhlkörper aus zwei Formteilen gebildet werden. Dazu weist die Formmaschine zwei gesonderte Formelemente auf, durch welche zwei in den jeweiligen zugeordneten Spannrahmen gehaltene, plattenartige Abschnitte gesondert, aber bei Bedarf auch geichzeitig verformbar sind. Die Spannrahmen haben an ihren Vertikalseiten in Vertikalrichtung angetriebene, z. B. ketten- oder raupenartige Greifelemente, die aus den Auslaßbereichen der Extrudereinrichtungen auslaufenden Kunststoffmassen seitlich führen und fixieren. Die Fixierung erfolgt nicht nur zum Zwecke der Einführung der Stränge in die Spannrahmen, sondern auch zum Zwecke der Verformung. Die Greifelemente werden nur in einer Einführungstellung des jeweiligen Spannrahmenpaares angetrieben. Sobald die Einführung der frisch extrudierten Platte oder des aus dem Extruder kommende Stranges in das Spannrahmenpaar abgeschlossen ist, werden die beiden Rahmenhälften zusammengefahren und dabei der Antrieb der Greifelemente gestoppt. Die beiden Rahmen eines jeweiligen Spannrahmenpaares weisen in Einführungsstellung einen geringen Abstand zueinander auf, so daß die extrudierte flächige Kunststoffmasse in das Spannrahmenpaar eingeführt werden kann. Aus dieser beabstandeten Einführungsstellung werden die Rahmen eines jeweiligen Spannrahmenpaares in eine Dichtstellung zusammengefahren. In der Dichtstellung werden die sich gegenüberliegenden Oberflächen der Kunststoffmasse rahmenartig durch die Spannrahmen dichtend beaufschlagt.When At the heart of the invention, it is considered below the outlet area to arrange the guiding and sealing devices of the at least one extruder device, which consist of at least one vertically arranged clamping frame, in what plate-like sections of the freshly extruded plastic material be introduced and there, d. H. in the tenter by a Form element of the molding device can be deformed. By the mutual arrangement of extruder and clamping frame and the Form elements of the molding apparatus can be an accelerated over the prior art Expire processing process. The machine is overall compact and very versatile, fittings can with high cycle numbers are produced. The guiding and sealing devices consist advantageously of parallel, vertically arranged, to each other movable clamping frame, thereby it becomes possible within the machine a twin-sheet process perform, out at the cave body two moldings are formed. For this purpose, the molding machine has two separate mold elements, by which two in the respective associated tenter held, plate-like sections separately, but if necessary also geichzeitig deformable. The clamping frames have driven on their vertical sides in the vertical direction, z. B. chain or caterpillar-like gripping elements, from the outlet areas the extruder expiring plastic masses laterally to lead and fix. The fixation is not just for the purpose of introducing the strands in the clamping frame, but also for the purpose of deformation. The Gripping elements are only in an introduction position of the respective Driven pair of clamping frames. Once the introduction of freshly extruded Plate or extruded from the extruder strand in the tenter frame pair is completed, the two frame halves are collapsed and while the drive of the gripping elements stopped. The two frames a respective clamping frame pair point in the insertion position a small distance from each other, so that the extruded sheet plastic material introduced into the tenter frame pair can be. From this spaced insertion position become the frame a respective clamping frame pair moved together in a sealing position. In the sealing position, the opposing surfaces of the Plastic mass like a frame acted upon by the clamping frame sealing.
In dieser Dichtstellung kann jedes Spannrahmenpaar in Kontakt mit der offenen Seite eines Blaskastens der Formvorrichtung gebracht werden, so dann erfolgt an dem noch warmen Kunststoffmaterial der tiefziehende Formvorgang. In dem Blaskasten ist dazu eine gegen das Spannrahmenpaar zustellbare Formhälfte angeordnet, die Formhälfte definiert die Endform des im Blaskasten verformten Kunststoffwandlungsteils.In this sealing position, each tenter pair in contact with the be brought open side of a blow box of the molding apparatus, so then takes place on the still warm plastic material of the thermoforming Molding process. In the blow box is one against the tenter frame pair deliverable mold half arranged, the mold half defines the final shape of the deformed in the blow box plastic conversion part.
Schließlich können die beiden Spannrahmenpaare in eine Verbindungstellung zusammengefahren werden, in welcher die aufeinander zuweisende Rahmen der beiden Spannrahmenpaare aneinander anliegen oder einen relativ geringen Abstand aufweisen. Schließlich können die beiden Blaskästen beidseitig an die zusammengefahrenen Spannrahmenpaare herangefahren werden, um die beiden für sich tiefgezogenen Wandungsteile zu einem Hohlkörper an definierten Stellen dichtend miteinander zu verbinden. Dazu werden die beiden Formteile aus den Blaskästen aufeinander zugestellt und beaufschlagen mit gegenseitigem Druck die beiden dazwischenliegenden Wandungsteile.Finally, the moved together two clamping frame pairs in a connection position be in which the juxtaposed frames of the two Tensioning frame pairs abut each other or a relatively small Have distance. After all can the two blow boxes on both sides moved to the collapsed tenter frame pairs, around the two for Deep-drawn wall parts to a hollow body at defined locations sealingly connect with each other. These are the two moldings from the blow boxes placed on each other and pressurize with mutual pressure the two intermediate wall parts.
Die Blaskästen bzw. die Rahmenpaare können im Wesentlichen einen identischen Aufbau haben, wobei die beiden in den Blaskästen angeordneten Formelemente meist unterschiedliche Ausformungen haben. Blaskästen und Rahmen können auf gemeinsamen, horizontal verlaufenden Führungselementen nach Art von Führungsschienen angeordnet sein, vorteilhafterweise sind für die Blaskästen und die Rahmenelemente Antriebsvorrichtungen vorgesehen, um die Blaskästen und die Rahmen in die für den jeweiligen Verfahrensschritt erforderliche Relativstellung zueinander zu bringen.The blow boxes or the frame pairs Kings NEN essentially have an identical structure, the two arranged in the blow boxes mold elements usually have different shapes. Blow boxes and frames can be arranged on common, horizontally extending guide elements in the manner of guide rails, advantageously for the blow boxes and the frame elements driving devices are provided to bring the blow boxes and the frame in the required relative to the respective process step relative to each other.
Um das Verfahren weiter zu beschleunigen, sind in der Formmaschine zwei Extrudereinrichtungen vorgesehen, die gleichzeitig aktivierbar sind, um in die Spannrahmen simultan plattenartige Kunststoffstränge einzuführen. Jedem Blaskasten ist dazu eine Extrudereinrichtung zugeordnet. Es ist auch möglich, über jeden Blaskasten eine Mehrzahl von Extrudereinrichtungen für unterschiedliche Kunsstoffmassen vorzusehen, die durch Verschieben oder Verdrehen einer Halteeinrichtung in Position bringbar sind. Dadurch wird die Flexibilität der Vorrichtung weiter erhöht. Mindestens eine Extrudereinrichtung kann als Co-Extrudereinrichtung ausgebildet sein, so daß in das zugeordnete Spannrahmenpaar plattenartige Abschnitte mit mehr als einer Kunststoffschicht eingeführt werden können.Around To further accelerate the process are in the molding machine provided two extruder devices that can be activated simultaneously are to introduce simultaneously into the tenter frame plate-like plastic strands. Each Blaskasten is associated with an extruder device. It is also possible, about everyone Blow box a plurality of extruder devices for different Kunsstoffmassen provide by moving or twisting a holding device can be brought into position. This will be the flexibility the device further increased. At least one extruder device can be designed as a co-extruder device, so that in the associated tenter frame pair plate-like sections with more can be introduced as a plastic layer.
Zur Ausformung ist die Unterseite eines jeden Rahmens aufklappbar oder aufschiebbar ausgebildet.to Formation is the bottom of each frame hinged or designed to be pushed.
Mit
der vorstehend kurz beschriebenen Vorrichtung kann das Verfahren
zur Herstellung von Hohlkörpern
aus extrudiertem plattenartigen Kunststoffmaterial mit folgenden
Verfahrensschritten hergestellt werden:
Zunächst werden plattenartige Stränge aus
Kunststoff extrudiert, die aus den Extruderöffnungen herauslaufenden Stränge werden
in rahmenartigen Elementen randseitig fixiert und dichtend beaufschlagt.
Die
so fixierten plattenartigen Stränge
werden so dann einseitig mit Vakuum- oder Luftdruck zur zumindest bereichsweisen
Verformung beaufschlagt, die so verformten Elemente werden so dann
durch gegenseitige Zustellung der beiden Formhälften zueinander miteinander
verbunden, insbesondere miteinander verschweißt, um aus den beiden verformten Strängen einen
Hohlkörper
zu bilden.
Dabei werden die zur Verformung der Kunststoffstränge erforderlichen
Werkzeughälften
aus den Blaskästen
herausgefahren, an welche die rahmenartigen Dichtelemente (Spannrahmen)
herangefahren werden.With the device briefly described above, the process for the production of hollow bodies of extruded plate-like plastic material can be produced with the following process steps:
First, plate-like strands of plastic are extruded, the extruded from the extruder openings strands are fixed edge-side elements in a frame-like and sealing applied.
The thus fixed plate-like strands are then then on one side with vacuum or air pressure for at least regional deformation applied, the deformed elements are then connected to each other by mutual delivery of the two mold halves to each other, in particular welded together to from the two deformed strands a hollow body form.
The tool halves required for the deformation of the plastic strands are moved out of the blow boxes to which the frame-like sealing elements (clamping frames) are moved.
Mit einem derartigen Verfahren ist es möglich, sowohl Hohlkörper als auch einzelne negative und positiv geformte Teile herzustellen. Dabei können alle üblichen Thermoplaste verarbeitet werden, insbesondere PVC, PE, PP, PS, ABS und PA. Gegenüber herkömmlichen Thermoformmaschinen ist es besonders vorteilhaft, daß keine teuren Halbzeuge für Weiterverarbeitung eingesetzt werden müssen, sondern in einem Arbeitsgang das Granulat sofort zum Endprodukt führt. Dabei sind relativ schnelle Taktzeiten zu erreichen. Außerdem läßt das Verfahren eine bessere Kontrolle der Wandstärkenverteilung zu. Teilinnenflächen können gegenüber der Blastechnik kalibriert werden, in einem Endprodukt können unterschiedliche Materialien bzw. Farben kombiniert werden.With Such a process makes it possible to use both hollow bodies as well also produce individual negative and positively shaped parts. It can all usual Thermoplastics are processed, especially PVC, PE, PP, PS, ABS and PA. Across from usual Thermoforming machines, it is particularly advantageous that no expensive semi-finished products for Further processing must be used, but in one operation the granules immediately lead to the final product. There are relatively fast cycle times to reach. Furthermore leaves the procedure better control of the wall thickness distribution too. Partial inner surfaces can be compared with the blowing technique calibrated, in a final product can be different materials or colors are combined.
