Description

Maschine zum Stauchen von Bolzen,;Nieten o. dgl., bei welcher das Werkstück an der Arbeitsstelle erhitzt wird. Vorldegende Erfindung bezieht sich auf solche Maschinen zur Massenherstellung von K'leineisenzeug, insbesondere Nieten, Schrauben, Bolzen u. dgl., bei welchen das Werkstück an, der Arbeitsstelle selbst erhitzt wird. Die Erfindung besteht darin, daß die Erhitzung des Werkstückes an der in die Maschine eingeführten Werkstange durch einen vom Maschinenantrieb gesteuerten Gasbrenner erfolgt, wobei dieser vor dem Vorschub der Werkstange aus deren Bahn: geschwungen lind .nach erfolgtem Vorschub wieder an die Werkstange bewegt werden kann. Der Gasbrenner kann außerdem um ein feststehendes Küken derart schwingbar gelagert sein, daß beim Ausschwingen desGasbrenners aus der Arbeitslage die Flamme kleingestellt wird.Machine for upsetting bolts, rivets or the like, in which the Workpiece is heated at the work site. Present invention relates to on such machines for the mass production of small iron items, especially rivets, Screws, bolts and the like, where the workpiece is attached to the work site itself is heated. The invention consists in that the heating of the workpiece the work bar introduced into the machine by one controlled by the machine drive Gas burner takes place, this before the advancement of the work rod from its path: swung lind. can be moved back to the work bar after the feed has taken place can. The gas burner can also swing around a stationary plug be stored so that when the gas burner swings out of the working position, the flame is reduced.

Die Reihenfolge der einzelnen Arbeitsgänge der Maschine ist ihrem besonderen Zweck angepaßt, die Arbeitsweise kann daher beispielsweise wie unten beschrieben erfolgen.The order of the individual operations of the machine is yours adapted to a special purpose, the mode of operation can therefore be, for example, as below described.

Auf der Zeichnung ist der Erfindungsgegenstand dargestellt, Fig. i ist eine Ansicht der betreffenden Maschinenteile, wobei die Brenner sich in Arbeitsstellung befinden. Fig. z zeigt die Werkstange in die Matrize vorgeschoben. Fig.3 ist eine Ansicht, bei welcher die Brenner aus der Arbeitsstellung herausgeschwungen sind. Fig. 4 zeigt die Werkstange von der Schere erfaßt, und Fig. 5 veranschaulicht die Stellung der Teile. nach dem Abschneiden und: bei wieder eiregeschwenkten Brennern,.The subject of the invention is shown in the drawing, FIG Fig. 3 is a view of the machine parts concerned with the torch in the working position are located. Fig. Z shows the work bar advanced into the die. Fig.3 is a View in which the burners have swung out of the working position. Fig. 4 shows the work bar grasped by the scissors, and Fig. 5 illustrates the Position of the parts. after cutting and: with the burners swiveled again.

Die Werkstange a wird kalt in die Vorschubzange b der Maschine eingeführt und gelangt vor einen an der Maschine angebrachten mehrflammigen Gasbrenner c. Durch. diesen wird die Stange a auf Schmiedehitze gebracht (Fig. i), worauf die Stange beim nächsten Vorschub in die Matrize d, welche geteilt sein kann, eingeführt wird (Fig.2). Während des Vorschubes der Stange a schwenkt der Brenner c aus und kommt infolge seiner Drehung um das feststehende Küken e zum Kleinbrennen (Fig. 3). Ist die Stange a weit genug in die Matrize d eingeführt, so- tritt durch Anschlag der Vorschubzange b bei: zweiteiliger Matrize deren Klemmvorrichtung und Schere f in Tätigkeit (Fig. 4). Sobald die Stange . festgeklemmt ist, greift die Vorschubzange b auf bestimmte Länge zurück. Die Schere f schneidet ab und bleibt als Widerl'ager hinter dem Bolzen. Gleichzeitig geht der Döbber g vor, während die Zange b wieder vorschiebt und der Brenner c einschwenkt (Fig. 5). Mit dem Rückgang des Döbbers g geht die Schere hoch und die Klemmvorrichtung auseinander, der Brenner schwenkt aus, die Stange a wird nochmals vorgeschoben und wirft das fertige Preßstück aus.The work bar a is inserted cold into the feed tongs b of the machine and comes in front of a multi-flame gas burner attached to the machine c. By. these the bar a is brought to forging heat (Fig. i), whereupon the bar at the next advance in the die d, which can be divided, is introduced (Fig. 2). During the advance of the rod a, the burner c swings out and comes as a result of its rotation around the stationary chick e to small burning (Fig. 3). is the rod a is inserted far enough into the die d, so that the Feed tongs b with: two-part die with clamping device and scissors f in Activity (Fig. 4). Once the pole. is clamped, the feed tong engages b back to a certain length. The scissors cut off and remain as an abutment behind the bolt. At the same time, the Döbber g goes ahead, while the pliers b again advances and the burner c swivels (Fig. 5). With the decline of the Döbbers The scissors go up and the clamping device opens, the torch swivels off, the rod a is advanced again and ejects the finished pressed piece.

Die einzelnen Teile der Maschine sind für verschiedene Größen der Preßstücke einstellbar. - Die Gaszuführung ist nur schematisch dargestellt. Die Gasflammen werden bei kleinstem Maß mit einem Gase höchster Heizkraft, ähnlich den für Schweiß- und Schneidbrenner verwendeten Gasen, gespeist, so daß das Anwärmen der Bolzen in sehr kurzer Zeit stattfindet und die Maschine in ihrer I.eistungfähigkei.`t denen für Herstellung schwächerer Stücke in kaltem Zustande mindestens gleichkommt.The individual parts of the machine are for different sizes of the Adjustable press pieces. - The gas supply is only schematic shown. The gas flames are similar to the smallest measure with a gas of the highest heating power the gases used for welding and cutting torches, so that the heating the bolt takes place in a very short time and the machine is efficient at least equal to those for the production of weaker pieces in a cold state.

Durch die vorliegende Maschine kommen die bisher verwendeten: Scheren und Öfen samt Bedienung in Fortfall. Ein Verbrennen des Werkstoffes oder Warten, bis das Werkstück genügend erhitzt ist, wird vermieden. Außerdem ist der Verschleiß der Maschine bedeutend' geringer als bei, Verwendung von Ofen, da die von den Öfen abfliegenden Kohlen- und Koksstäubchen die beweglichen Teile der Maschine ausschleifen. Ein Arbeiter kann mehrere der vorliegenden Maschinen bedienen. Der Gasverbrauch der Maschine wird durch das Kleinbrennen in der ausgeschwenkten Stellung des Brenners äußerst gering gehalten, so daß durch die Maschine eine bedeutende Verringerung der bisherigen Herstellungskosten erreicht wird.Through the present machine come the previously used: Scissors and ovens including service no longer available. Burning the material or waiting until the workpiece is sufficiently heated is avoided. Also, there is wear and tear the machine is significantly less than when using the oven, since that of the ovens grind the moving parts of the machine out of the flying coal and coke dust. One worker can operate several of the present machines. The gas consumption the machine is opened by the small burning in the swiveled-out position of the burner kept extremely small, so that a significant reduction by the machine the previous production costs is achieved.
