Description
Anordnung hydraulischer Pressen zur Herstellung von Rohren durch Stoßen (Ziehen) Die vorliegende Erfindung bezieht sich auf eine Anordnung hydraulischer Pressen zum Lochen und Stoßen (Ziehen) von Metallblöcken, wie solche beispielsweise zur Herstellung von Geschossen. Hohlkörpern für Stahlflaschen usw. bekannt sind.Arrangement of hydraulic presses for the production of pipes by slotting (Pulling) The present invention relates to an arrangement of hydraulic Pressing for punching and pushing (drawing) metal blocks such as those for example for the production of projectiles. Hollow bodies for steel bottles, etc. are known.
Die Abmessungen einer Lochpresse und einer Ziehpresse (Stoßbank) sind im allgemeinen stark verschieden: denn die Lochpresse hat ungefähr den zwei- bis dreifachen Druck der Ziehpresse, und die Ziehpresse hat ungefähr den zweieinhalb- bis dreifachen Hub der Lochpresse, und an die Lochpresse muß die Bedingung sehr guter Führung des Stempels bzw. Dornes gestellt werden, während die Führung des Dornes bei der Ziehpresse weniger wichtig ist.The dimensions of a punch press and a drawing press (push bench) are generally very different: for the hole press has approximately the two to triple pressure of the drawing press, and the drawing press has about the two and a half up to three times the stroke of the piercing press, and the condition must be very high on the piercing press good guidance of the punch or mandrel are provided, while the guidance of the Dornes is less important in the drawing press.
Man hat nun diese -Maschinen meistens vollständig voneinander getrennt, indem neben einer stehenden Lochpresse eine liegende Ziehpresse angeordnet wurde, oder man hat auch bei leichteren Maschinen beide Pressen in stehender Anordnung nebeneinander gestellt. Beide Ausführungsarten ergeben Maschinen mit unnötiger Rauminanspruchnahme. großem Gewicht und nicht günstiger Bedienungsmöglichkeit. Mit der vorliegenden Erfindung soll nun eine Maschine entwickelt werden, die preiswert und dabei technisch einwandfrei ist, also den Bedingungen in bezug auf Preßdruck. Hub und Kolbenführung genügt. und das wird nach der Erfindung dadurch erreicht, daß eine stehende Lochpresse, deren Stempel in bekannter Weise zwischen zwei Ständern angeordnet ist, an dem einen Ständer eine stehende Ziehpresse zum Stoßen der Blöcke trägt. deren Dorn von einem besonderen Druckzvlinder und außerhalb der Pressenständer vorgetrieben wird.These machines have now mostly been completely separated from each other, by placing a horizontal drawing press next to a standing punch press, or you can have both presses in an upright position, even with lighter machines placed side by side. Both types of construction result in machines that take up unnecessary space. great weight and not convenient to use. With the present invention A machine is now to be developed that is inexpensive and technically flawless is, that is, the conditions relating to the pressing pressure. Stroke and piston guide are sufficient. and this is achieved according to the invention in that a standing punch press, whose stamp is arranged in a known manner between two stands, on the one Stand carries a standing drawing press for pushing the blocks. whose thorn of one special Druckzvlinder and is driven outside the press frame.
Es sind zwar mechanisch angetriebene Pressen bekannt, die beide in einem Ständer untergebracht sind, jedoch nicht wie eine Loch- und Ziehpresse gesonderten Antrieb. sondern gemeinsamen Antrieb haben und die durchweg für Präge- und Stanzarbeiten gebraucht werden. Im vorliegenden Fall handelt es sich jedoch um ein hydraulische: Pressenpaar mit gesondertem Antrieb für jede einzelne Presse, bei welchem die kurzhübige. den großen Druck bei guter Führung benötigende Lochpresse innerhalb des rahmenartigen Ständers und die den geringeren Druck, größeren Hub und weniger gute Führung benötigende Ziehpresse außerhalb des Ständers angebracht werden soll. um eine preiswerte, leichte und gute Bauart zu erhalten. die eine gute Bedienung der 'Maschine ergibt.Mechanically driven presses are known, both in are housed in a stand, but not separate like a punching and drawing press Drive. but have a common drive and they are all for embossing and punching work to be needed. In the present case, however, it is a hydraulic one: Press pair with separate drive for each individual press, in which the short-stroke. the high pressure with good guidance required punch press within the frame-like Stand and the lower pressure, larger stroke and less good guidance required Drawing press is to be attached outside of the stand. an inexpensive, light one and to get good construction. which results in good operation of the machine.
Der besseren Verständlichkeit halber ist das Pressenpaar auf der Zeichnung in einer Ansicht dargestellt. ES ist a der rahmenartige Ständer des Pressenpaares, in dessen Mitte die Lochpresse angeordnet ist. b ist der Preßzylinder der Lochpresse, in welchem sich der Plunger c befindet. Der Preßdruck wird über das bewegliche Querhaupt d dem Lochwerkzeug e übermittelt. Im unteren Teil des Ständers ist in der Mitte die Matrize f angebracht, in welcher der Lochvorgang stattfindet.For the sake of clarity, the pair of presses is on the drawing shown in one view. IT is a frame-like Stand of the pair of presses, in the middle of which the punch press is arranged. b is the press cylinder the punch press, in which the plunger c is located. The pressing pressure is over the movable crosshead d transmitted to the punching tool e. In the lower part of the stand the die f, in which the punching process takes place, is attached in the middle.
Seitlich am Ständer ist die Ziehpresse angeordnet. g ist der Ziehzylinder, welcher in einem an dem walzenständerförmigen Rahmen angebrachten Auge h befestigt ist. i ist der Ziehdorn, k der Ziehringhalter, in welchem die Ziehringe L angebracht sind.The drawing press is arranged on the side of the stand. g is the pull cylinder, which is attached to an eye h attached to the roll stand-shaped frame is. i is the drawing mandrel, k is the drawing ring holder in which the drawing rings L are attached are.
Der Arbeitsvorgang ist folgendermaßen: Der Rohling wird in der Lochpresse im Gesenk f unter Stehenlassen eines Bodens gelocht, wobei die Lochpresse eine gute Führung aufweisen muß. Dann wird das vorgelochte Werkstück in der Ziehpresse durch mehrere Ziehringe gestoßen und dabei gestreckt.The working process is as follows: The blank is in the hole press punched in the die f while leaving a bottom standing, the punch press being a good one Must have leadership. Then the pre-punched workpiece is through in the drawing press several pull rings pushed and stretched in the process.
Dadurch. daß die Lochpresse innerhalb und die Ziehpresse außerhalb des rahmenartigen Ständers angeordnet ist, ist eine gute Kraftübertragung auf die beiden Ständerwangen und eine gute Führung des Preßkolbens möglich und gleichzeitig für die Ziehpresse Raum geschaffen zur Ausübung eines langen Preßhubes, wobei der wesentlich geringere Ziehdruck durch den ganzen Ständeraufbau gut aufgenommen wird.Through this. that the punch press inside and the drawing press outside of the frame-like stand is arranged, is a good power transmission to the both stand cheeks and good guidance of the plunger possible and at the same time created space for the drawing press to exercise a long press stroke, the significantly lower drawing pressure is well absorbed by the entire stand structure.
