Abstract

The main patent is for a press tool to produce a double sink unit from sheet metal. This addition to the patent overcomes the need to use a double acting press. The pressure plate supports the die for forming the sink bodies which house the pressure pistons attached to the drawing apparatus. The sheet metal blank is placed in position and the downward motion of the press tool first grips the blank between the plates. Further downward motion forces the punches to form the sink unit whilst the edges of the blank are held by hydraulic pressure in the cylinder which is controlled by a valve.

Description

Vorrichtung zum Tiefziehen von Spültischen Zusatz zum Patent (Patentanmeldung P 22 61 955.2) Die Erfindung nach dem Hauptpatent ......... (Patentanmeldung P 22 61 955.^)bezieht sich auf ein Verfahren und eine Vor -richtung zum Tiefziehen von Spültischen mit zwei durch einen Steg voneinander getrennten Spülbecken aus einer Blechplatine. Bei der Ausführung nach dem Hauptpatent ist die separate Anordnung und Führung eines Blechhalters erforderlich, die als Anwendungsvoraussetzung eine doppeltwirkende Ziepresse hat. Device for deep-drawing sink units Addition to the patent (patent application P 22 61 955.2) The invention according to the main patent ......... (patent application P 22 61 955. ^) Relates to a method and a device for deep drawing of Sink units with two sinks separated from one another by a bridge from one Sheet metal blank. In the execution according to the main patent, the separate arrangement and guidance of a sheet metal holder required, which is a prerequisite for use has double-acting drawing press.

Um auch von oben einfach wirkende Pressen einsetzen zu können, hat sich die vorliegende Erfindung daher zur Aufgabe gemacht, den Blechhaltering derart in das Oberwerkzeug einzubauen, daß die gesamte Ziehvorrichtung auch auf einfachwirkenden Pressen eingesetzt werden kann.In order to be able to use single-acting presses from above The present invention therefore set itself the task of the sheet metal retaining ring in such a way to install in the upper tool that the entire pulling device also on single-acting Pressing can be used.

Dies wird erfindungsgemäß dadurch gelöst, daß der Niederhaltor Bestandteil des Oberwerkzeuges ist, und zwar derart, daß der Niederhalter über druckinittelbetätigte Zylinder-kolben führungen gegenüber den am Werkzeugoberteil befestigten Ziehstempoln axial verschieblich an der Stößelsohle angreift.This is achieved according to the invention in that the hold-down gate is a component of the upper tool is in such a way that the hold-down device is actuated by means of pressure Cylinder-piston guides opposite the drawing punch poles attached to the upper part of the tool engages axially displaceably on the tappet sole.

In weiterer Ausgestaltung der Erfindung ist noch vorgesehen, du Abwärtsbewegung des Niederhalters durch Anschläge zu begrenzen. Durch diese in das Werkzeugoberteil lntegierte Blechhalterführung entfällt für den Blechhalter vom Pressenstößel abhängige zusätzliche Antriebsfunktion, wodurch die Einsatzmöglichkeit auf einfachwirkenden Pressen geschaffen ist. In der Zeichnung ist ein Ausführungsbeispiel der Erfindung als Schnitt dargestellt.In a further embodiment of the invention it is also provided that you move downwards of the hold-down device by means of stops. Through this into the upper part of the tool Integrated blank holder guide is not required for the blank holder from the press ram dependent additional drive function, which means that it can be used on single-acting Pressing is created. In the drawing is an embodiment of the invention shown as a section.

Der auf der Aufspannplatte 1 sitzende Wasserkasten 2 ist mit einem Blechauflagering 3 versehen. in den die für das hydro-mechanische Ziehen einer Platine 4 erforderlichen Dichtung 5 eingelassen sind. Die im Wasserkasten 2 sitzenden Verdrängerkolben 6 sind dabei Uber den Ziehapparat 7 geftihrt. Das an der Stößelsohle 8 befestigte Oberwerkzeug besteht aus den beiden Ziehstempeln 10, die an der Aufspannplatte 9 befestigt sind. Ebenso an dieser Platte 9 ist der Blechhalter 11 mit dem Blechhaltering 12 in Richtung des Pfeiles 13 relativ zu den Ziehstempeln 10 beweglich er Zylinder -Kolben-Einheiten 14, 20 und Begrenzungsanschläge 15 befestigt.The seated on the platen 1 water tank 2 is with a Sheet metal support ring 3 provided. in the one for the hydro-mechanical drawing of a sinker 4 required seal 5 are embedded. The displacement pistons located in the water tank 2 6 are guided over the pulling device 7. The attached to the tappet base 8 The upper tool consists of the two drawing punches 10, which are attached to the clamping plate 9 are attached. The sheet metal holder 11 with the sheet metal retaining ring is also on this plate 9 12 movable in the direction of arrow 13 relative to the drawing punches 10 he cylinder Piston units 14, 20 and limit stops 15 attached.

Der Ziehvorgang läuft hierbei folgendermaßen ab: Nach Einlegen der Platine 4 erfolgt zunädist das Schließen des Werkzeuges durch Herlmterffihren des in seiner Ausgangsstellung dargestellten Oberwerkzeuges in Richtung des abwärts gerichteten Teiles von Pfeil 13. Sobald der Blechhaltering 12, an der auf dem Ring 3 aufliegenden Platine 4 zur Anlage kommt, erfolgt Druckaufbau tfber das Flüssigkeitssystem 17 18, 19. Die Ziebstempel 10 treffen erst bei weiterer Abwärtsbewegung der Stößelsohle 8 auf die Blechplatine 4 auf und leiten den Umformvorgang ein. Die Kolben 14 bewegen sich dabei in den Zylinderräumen 20 zwangsläufig abwärts, wobei die Druckflüssigkeit über das System 17, 18, 19 aus diesen Räumen verdrängt wird. Nach erfolgtem Ziehvorgang wirkt der in diesem system vorhandene Druck so lange auf den Blechhalter 11 bis die Stößel 10 aus dem gezogenen Teil ausgetreten sind und die Anschläge 15 in ihrer Aufwärtsbewegung diesen vom Werksttick abheben.The drawing process proceeds as follows: After inserting the Board 4 is initially the closing of the tool by Hermterffihren the upper tool shown in its starting position in the downward direction directed part of arrow 13. As soon as the sheet metal retaining ring 12, on the on the ring 3 on board 4 comes into contact, pressure build-up takes place via the fluid system 17, 18, 19. The push punches 10 do not hit until the ram sole continues to move downwards 8 on the sheet metal blank 4 and initiate the forming process. Move the pistons 14 in the cylinder chambers 20 inevitably downwards, the pressure fluid is displaced from these spaces via the system 17, 18, 19. After the drawing process has taken place the pressure present in this system acts on the sheet metal holder 11 bis for so long the plungers 10 have emerged from the drawn part and the stops 15 in their Upward movement lift it off the workpiece.
