Description

Ziehpresse für Schachtelteile. Die Erfindung bezieht sich auf Ziehpressen, welche dazu dienen, Schachtelteile, insbesondere Schachteldeckel, mit einer Papierdecke zu vereinigen, die an ihrer Unterseite mit einer Klebstofschicht versehen ist. Dabei wird der Schachteldeckel bekanntlich auf einen feststehenden Unterstempel in Form eines rechteckigen Blockes gestülpt. Dann wird das an der Unterseite mit trockenem Klebstoff versehene Papierblatt aufgelegt, welches die Papierdecke bilden soll. Die Vereinigung geschieht durch einen im Querschnitt U-förmigen Oberstempel, welcher beheizt ist und sich auf den Unterstempel niedersenkt. Durch die Wärmewirkung wird der Klebstoff flüssig, und der Oberstempel drückt die Ränder des Papierblattes an die Zargen des Pappdeckels an.Drawing press for box parts. The invention relates to drawing presses, which are used to provide box parts, in particular box lids, with a paper cover to unite, which is provided on its underside with a layer of adhesive. Included the box lid is known to be on a fixed lower punch in the form of a rectangular block. Then the bottom is covered with dry Adhesive-provided paper sheet is placed, which is to form the paper cover. The union is done by a cross-sectionally U-shaped upper punch, which is heated and lowers itself on the lower stamp. The heat effect is the glue is liquid, and the upper punch presses the edges of the sheet of paper on the frames of the cardboard cover.

Das bekannte Werkzeug ist auf der Zeichnung in Abb. i schematisch im senkrechten Querschnitt dargestellt. Auf den Unterstempel a aus Metall ist der Pappdeckel b gestülpt. Der im Querschnitt U-förmige Oberstempel c vereinigt die Papierdecke d mit dem Pappdeckel, wobei er die Ränder ,e der Papierdecke an die Zargen des Deckels andrückt.The known tool is shown schematically in the drawing in Fig. I in vertical cross section. The cardboard cover b is placed on the lower die a made of metal. The upper punch c, which is U-shaped in cross-section, unites the paper cover d with the cardboard cover, pressing the edges e of the paper cover against the frame of the cover.

Sobald Unstimmigkeiten hinsichtlich der Stärke des für den Schachteldeckel verwendeten Pappmaterials auftreten, welche bekanntlich unvermeidlich sind, wird die sichere Vereinigung der Papierdecke mit der umgebogenen Zarge des Schachteldeckels in Frage gestellt, wie das in Abb. a angedeutet ist. Es findet entweder gar keine oder nur eine so lockere Verbindung statt, daß der Papierrand später von der Zarge losplatzt.As soon as there is a disagreement about the strength of the box lid used cardboard material, which is known to be inevitable, will occur reliable connection of a paper cover with a bent frame of a box cover questioned, as indicated in Fig. a. It either doesn't find any or just such a loose connection that the edge of the paper will later be removed from the frame bursts out.

Diesem Übelstande hat man bereits bei Ziehpressen, welche mit einem blockförmigen Oberstempel arbeiten, der in einen entsprechend zugeschnittenen Behälter mit festen Seitenwänden eintaucht, dadurch zu begegnen versucht, daß man den blockförmigen Oberstempel aus einem festen Kern und daran bewegbar angeordneten und durch Federn nach außen preßbaren Seitenplatten hergestellt hat. Natürlich kann man auch die umglekehrte Anordnung treffen, wenn ein im Querschnitt U-förmig profilierter Oberstempel mit festen Seitenwänden benutzt wird, indem man die federnd nach außen preßbaren Seitenplatten an dem blockförmigen Unterstempel anordnet.One already has this disadvantage with drawing presses, which with a block-shaped upper punch work, which is in a suitably cut container immersed with solid side walls, trying to counteract that one of the block-shaped Upper stamp from a fixed core and movably arranged thereon and made outwardly compressible side panels by springs. Of course you can you also meet the reverse arrangement if a U-shaped profile in cross-section Upper punch with solid side walls is used by turning the resilient outward arranges pressable side plates on the block-shaped lower punch.

Demgegenüber wird erfindungsgemäß die Aufgabe dadurch gelöst, daß der Unterstempelblock aus nachgiebigem Stoff, z. B. Kautschuk oder Gummi, besteht, der sich unter dem Preßdruck seitlich ausdehnt und dadurch die Deckelzargen fest an die Papierdecke andrückt. Bei dieser Ausführung fallen alle mechanisch verwickelten und baulich umständlichen Einrichtungen fort. Hier sind keine Federn, keine verschiebbaren Seitenflächen usw. mehr erforderlich. Hier erfüllt der als glatter Rechteckkörper ausgebildete Unterstempel aus elastischem Stoff allein die Aufgabe.In contrast, the object is achieved according to the invention in that the lower die block made of flexible material, e.g. B. rubber or rubber, which expands laterally under the pressure and thereby secures the cover frames presses against the paper cover. In this execution, all mechanically entangled ones fall and structurally cumbersome facilities. There are no springs here, no sliding ones Side faces etc. are more required. Here it fulfills as a smooth rectangular body Trained lower stamps made of elastic material do the job alone.

Die neue Ziehpresse ist in Abb.3 in einer Ausführung dargestellt, bei welcher auf dem nachgiebigen Unterstempelblock a' noch eine Metallplatte i befestigt ist, die dazu dient, an der Innenseite des Deckels Prägungen zu erzeugen. Diese Metallplatte/ tritt mit Zapfen g durch den nachgiebigen Teil a' des Unterstempels hindurch. Die Zapfen werden durch Schrauben h festgelegt, welche von unten her durch Öffnungen i des Unterstempelträgers k hindurch in zentrale Gewindebohrungen der Zapfen g eingeschraubt werden.The new drawing press is shown in Figure 3 in an embodiment, in which a metal plate i is attached to the flexible lower die block a ' which is used to create embossments on the inside of the lid. These Metal plate / enters with pin g through the flexible part a 'of the lower punch through. The tenons are fixed by screws h, which from below through Openings i of the lower punch carrier k through into the central threaded holes Pin g are screwed in.

Der nachgiebige Unterstempelteil a' wird auf den Trägerkörper k aufvulkanisiert, und die Schrauben k werden nur so weit angezogen, daß die Platte f fest auf der nachgiebigen Unterlage a ruht, ohne daß eine Zusammendrückung der Unterlage stattfindet.The flexible lower punch part a 'is vulcanized onto the carrier body k, and the screws k are only tightened so far that the plate f is firmly on the yielding pad a rests without a compression of the pad takes place.

Senkt sich nun der Oberstempel c nieder, dann drückt er den Unterstempelblock a' zusammen, wobei die Zapfen g sich in den Bohrungen l des Trägerkörpers k verschieben. Durch das Zusammendrücken des nachgiebigen Blockes a' wird derselbe seitlich in Richtung der eingezeichneten Pfeile auseinandergepreßt, und dabei werden die Zargen des Schachteldeckels b fest an die umgebogenen Ränder e der Papierdecke gedrückt.If the upper punch c is lowered, then it presses the lower punch block a 'together, the pins g moving in the bores l of the support body k. By compressing the resilient block a ', the same is laterally in The direction of the arrows are pressed apart, and the frames of the box lid b pressed firmly against the bent edges e of the paper cover.

B. Kautschuk oder Gummi, zusammenarbeitet, welcher sich unter dem Preßdruck seitlich ausdehnt und dadurch die Deckelzarge fest an die mit ihm zu verbindende Papierdecke andrückt. PATENT CLAIM: Drawing press for box parts that are to be combined during the drawing process with a paper cover provided with adhesive on the underside using an expandable core punch, characterized in that the upper punch, which is U-shaped and heated in cross section, is equipped with a lower punch made of flexible material, e.g. . B. rubber or rubber, works together, which expands laterally under the pressure and thereby presses the cover frame firmly against the paper cover to be connected to it.
