Description

Die Erfindung betrifft eine kraftbetriebene Biegemaschine für Faßdauben. Bei den bisher bekannten Maschinen dieser Art werden die Biegearme durch komplizierte Mechanismen, wie Kniehebelgelenke, Kurbelarme usw., bewegt. Demgegenüber besteht die Erfindung darin, daß sowohl die die Biegeform der Faßdaube erzeugenden, mit Unterdruckstücken versehenen Biegearme über doppelarmige Hebel als auch das Oberdruckstück über eine senkrechte Stange durch ein System von drei entsprechend geformten Kurvenscheiben derart bewegt werden, daß die Faßdaube durch die Unterdruckstücke und das Oberdruckstück gebogen und gleichzeitig zusätzlich durch die am Ende der Biegearme einstellbar angeordneten Stauchbacken in der Längsrichtung gestaucht wird. Die Oberseite der Biegearme ist der Krümmung der Faßdaube entsprechend konkav gewölbt, so daß ein einwandfreies Biegen der Faßdaube gewährleistet ist.The invention relates to a power-operated bending machine for barrel staves. In the previously known machines of this type, the bending arms are complicated by Mechanisms such as toggle joints, crank arms, etc. move. In contrast, there is the invention is that both the bending shape of the barrel stave generating with Bending arms provided with vacuum pieces via double-armed levers as well as the upper pressure piece via a vertical rod through a system of three correspondingly shaped cam disks be moved in such a way that the barrel stave through the vacuum pieces and the upper pressure piece curved and at the same time also adjustable by means of the one at the end of the bending arm arranged upsetting jaws is compressed in the longitudinal direction. The top of the Bending arms is the curvature of the barrel stave correspondingly concave, so that a perfect bending of the barrel stave is guaranteed.

Durch diese Ausbildung der Biegemaschine wird gegenüber dem Bekannten der Vorteil erreicht, daß maschinenherstellungsmäßig sehr komplizierte Mechanismen, wie Kniehebelgelenke, Kurbelarme usw., wegfallen, während arbeitsmäßig ein idealer Halsbauch statt des unschönen Spitzbauches an der Faßdaube erzielt wird.This training of the bending machine is compared to the known the advantage achieved that mechanically very complicated mechanisms, such as toggle joints, crank arms, etc., are omitted, while an ideal one in terms of work Neck belly is achieved instead of the unsightly pointed belly on the barrel stave.

Eine Faßdauben-Biegemaschine nach der Erfindung ist in der Zeichnung, und zwar in Abb. i in Vorderansicht, in Abb. 2 in Seitenansicht und in Abb.3 mit einem Schnitt durch den Getriebeteil, dargestellt.A stave bending machine according to the invention is shown in the drawing, namely in Fig. i in front view, in Fig. 2 in side view and in Fig.3 with a section through the transmission part.

Die Biegemaschine besteht aus einem kräftigen Ständer i, in welchem sich unten ein motorisch betriebenes Schneckengetriebe 2 befindet. Dessen Schneckenrad dreht die drei Kurvenscheiben 3, 4, 5. Die Kurvenscheiben 3 und 4 heben über zwei doppelarmige Hebelpaare 6 mit Ablaufrollen 7 die anfangs waagerecht liegenden Biegearme 8 an. Die Biegearme 8 sind am Ende mit durch Handrad 9 und Gewindespindel io einstellbaren Stauchbalken i i versehen und tragen auf ihrer der Krümmung der Faßdaube entsprechend konkav gewölbten Oberseite eine Anzahl gliederartig verbundener Unterdruckstücke 12, während ein mittleres Unterdruckstück 13 starr in einer Bolzenlagerung 14 steckt. Die hintere Kurvenscheibe 5 zieht über eine senkrechte Führungsstange 15 mit Ablaufrolle 16 ein in einem einstellbaren Spannkopf 17 befindliches Oberdruckstück 18 nach unten. Die zwischen die Stauchbacken i i eingelegte dampfgebrühte Faßdaube i9 wird durch die hochgehenden Biegearme 8 zwischen den Unterdruckstücken 12 und 13 und dem heruntergehenden Oberdruckstück 18 eingepreßt und in die gewünschte Form gebogen, während gleichzeitig zusätzlich die durch die Biegearmbewegung sich nähernden Stauchbacken i i die Daube infolge der Form der Kurvenscheiben 3, 4 fortwährend stauchen, wodurch ein Brechen der unteren Daubenfasern vermieden wird. Die Stauchwirkung kann ferner noch durch exzentrische Verstellung der Kurvenscheibe 4 eingestellt werden.The bending machine consists of a sturdy stand i in which a motorized worm gear 2 is located below. Its worm wheel rotates the three cams 3, 4, 5. The cams 3 and 4 lift over two double-armed pairs of levers 6 with discharge rollers 7 the initially horizontally lying bending arms 8 at. The bending arms 8 are at the end with adjustable by hand wheel 9 and threaded spindle io Compression bars i i provided and wear on their corresponding to the curvature of the barrel stave concavely curved top a number of link-like connected vacuum pieces 12, while a central vacuum piece 13 is stuck rigidly in a pin bearing 14. The rear cam 5 pulls over a vertical guide rod 15 with a run-off roller 16 an upper pressure piece 18 located in an adjustable clamping head 17 downwards. The steam-brewed barrel stave i9 inserted between the upsetting jaws i i is through the upward bending arms 8 between the vacuum pieces 12 and 13 and the downward Upper pressure piece 18 pressed in and bent into the desired shape while at the same time In addition, the crushing jaws i i the stave, which are approaching due to the bending arm movement Due to the shape of the cam disks 3, 4 continuously compress, causing breaking of the lower stave fibers is avoided. The upsetting effect can also be achieved by eccentric adjustment of the cam 4 can be set.
