Abstract

An arrangement for manufacturing pressed shapes and similar structures in which loading and unloading arms are driven by displacement drive mechanisms. These displacement drive mechanisms have at least two displacement cylinders with strokes that are shorter than either the displacement path of the loading arm or the displacement path of the unloading arm. There is no force transmission from the cylinders to the loading and unloading arms to provide for minimum use of driving power during acceleration intervals when the loading and unloading arms move from a stationary position to a displacement speed.

Description

Die Neuerung bezieht sich auf eine Vorrichtung zum Herstellen von gepreßten Formteilen od. dgl., mit einer Presse, einer Beschick- und einer Entleervorrichtung, wobei zur Pressenbe­schickung ein von einem Verschiebeantrieb angetriebener Beschick­arm und zur Pressenentleerung ein von einem Verschiebeantrieb angetriebener Entleerarm eingesetzt sind.The innovation relates to a device for producing pressed molded parts or the like, with a press, a loading and an emptying device, wherein a loading arm driven by a displacement drive and an emptying arm driven by a displacement drive are used for press loading.

Bei einer bekannten Vorrichtung der vorgenannten Art werden der Beschick- und der Entleerarm von je einem elektromotorischen Verschiebeantrieb angetrieben.In a known device of the aforementioned type, the loading arm and the emptying arm are each driven by an electromotive displacement drive.

Ein derartiger Verschiebeantrieb, der während eines Preßzyklus den Beschick- bzw. Entleerarm zweimal vom Stillstand auf die Höchstgeschwindigkeit bescheunigen und zweimel von der Höchst­geschwindigkeit bis zum Stillstand verzögern muß, ist jedoch wegen seiner großen Schwungmasse nur für verhältnismäßig nie­drige Verschiebegeschwindigkeiten geeignet.Such a shifting drive, which has to accelerate the loading or unloading arm twice from standstill to the maximum speed and has to decelerate two times from the maximum speed to standstill during a press cycle, is however only suitable for relatively low shifting speeds because of its large flywheel mass.

Niedrige Verschiebegeschwindigkeiten des Beschick- und des Ent­leerarms wirken sich jedoch ungünstig auf die Beschick- und die Entleerzeit der Presse aus.However, low shifting speeds of the loading and unloading arm have an adverse effect on the loading and unloading time of the press.

Der Neuerung liegt die Aufgabe zugrunde, für den Beschick- und den Entleerarm je einen Verschiebeantrieb zu schaffen, der eine kurze Beschick- bzw. Entleerzeit der Presse ermöglicht.The innovation is based on the task of creating a sliding drive for the loading arm and the emptying arm, which enables a short loading and emptying time for the press.

Neuerungsgemäß wird diese Aufgabe dadurch gelöst, daß jeder Verschiebeantrieb für den Beschick- bzw. Entleerarm aus min­destens zwei Hubzylindern besteht, deren Hublängen kürzer als der Verschiebeweg des Beschick- bzw. Entleerarms sind.According to the invention, this object is achieved in that each displacement drive for the loading or unloading arm consists of at least two lifting cylinders, the stroke lengths of which are shorter than the displacement path of the loading or unloading arm.

Nach einem weiteren Merkmal der Neuerung sind jedem Verschiebe­antrieb zwei Andrückvorrichtungen zum Halten des Beschick- bzw. Entleerarms in den Endlagen des Verschiebeweges zugeordnet.According to a further feature of the innovation, two pushing devices for holding the loading or unloading arm in the end positions of the shifting path are assigned to each shifting drive.

Jede Andrückvorrichtung weist einen Andrückzylinder und einen Andrückhebel auf.Each pressure device has a pressure cylinder and a pressure lever.

Jeder Andrückhebel weist eine Andrückrolle auf.Each pressure lever has a pressure roller.

Zweckmäßigerweise ist jeder Hubzylinder ein Pneumatikzylinder.Each lifting cylinder is expediently a pneumatic cylinder.

Im folgenden wird die Neuerung anhand einer Zeichnung, in der ein Ausführungsbeispiel schematisch dargestellt ist, näher beschrieben.The innovation is described in more detail below with reference to a drawing in which an exemplary embodiment is shown schematically.

Es zeigt

  • 3 shows a section along the line III-III in FIG. 2.

Eine Vorrichtung 1 zum Herstellen von gepreßten Formteilen enthält eine hydraulische Presse 2, eine Beschickvorrichtung 3 und eine Entleervorrichtung 4.A device 1 for producing pressed molded parts contains a hydraulic press 2, a loading device 3 and an emptying device 4.

Die hydraulische Presse 2 besitzt einen Pressenrahmen 5, dessen untere Traverse 6 ein unteres Formwerkzeug 7 trägt.The hydraulic press 2 has a press frame 5, the lower crossmember 6 of which carries a lower mold 7.

An einer verschiebbaren Pressentraverse 8 ist ein oberes Form­werkzeug 9 befestigt. Angetrieben wird die verschiebbare Pressen­traverse 8 von einem Preßzylinder 10.An upper molding tool 9 is fastened to a displaceable press crossmember 8. The displaceable press crossmember 8 is driven by a press cylinder 10.

Die Beschickvorrichtung 3 und die Entleervorrichtung 4 weisen je einen an dem Pressenrahmen 5 befestigten Ausleger 11, 12, eine heb- und senkbare Säule 13, 14 und einen Führungsträger 15, 16 auf.The loading device 3 and the emptying device 4 each have a boom 11, 12 fastened to the press frame 5, a column 13, 14 which can be raised and lowered and a guide bracket 15, 16.

Die Säule 13 der Beschickvorrichtung 3 ist mit dem Führungs­träger 15, die Säule 14 der Entleervorrichtung 4 mit dem Führungsträger 16 fest verbunden.The column 13 of the loading device 3 is firmly connected to the guide carrier 15, the column 14 of the emptying device 4 to the guide carrier 16.

Die Hub- und Absenkbewegung einer jeden Säule 13, 14 erzeugt ein Getriebemotor 17, 18 über ein Ritzel (nicht dargestellt) und eine Zahnstange 19, 20.The lifting and lowering movement of each column 13, 14 generates a geared motor 17, 18 via a pinion (not shown) and a rack 19, 20.

Der Führungsträger 15 dient der waagerechten Führung eines Be­schickarms 21 und der Aufnahme eines Verschiebeantriebes 22 für den Beschickarm 21. An dem Beschickarm 21 ist eine Greifvor­richtung 23 zum Ergreifen und Ablegen von Preßgut 24 angeordnet.The guide carrier 15 serves for the horizontal guidance of a loading arm 21 and for receiving a displacement drive 22 for the loading arm 21. A gripping device 23 is arranged on the loading arm 21 for gripping and depositing material 24 to be pressed.

Der Führungsträger 16 dient der waagerechten Führung eines Ent­leerarms 25 und der Aufnahme eines Verschiebeantriebes 26 für den Entleerarm 25. An dem Entleerarm 25 ist eine Greifvor­richtung 27 zum Ergreifen und Ablegen eines gepreßten Form­teils 28 angeordnet.The guide support 16 is used for the horizontal guidance of an emptying arm 25 and for receiving a displacement drive 26 for the emptying arm 25. A gripping device 27 is arranged on the emptying arm 25 for gripping and depositing a pressed molded part 28.

Die Führungsträger 15, 16 sind völlig gleich ausgebildet, eben­so der Beschickarm 21 und der Entleerarm 25 sowie die Ver­schiebeantriebe 22, 26.The guide supports 15, 16 are of completely identical design, as are the loading arm 21 and the emptying arm 25, as well as the displacement drives 22, 26.

Jeder Führungsträger 15, 16 hat acht Führungsrollen 29, 30, 31, 32, 33, 34, 35, 36 mit waagerechter Drehachse und vier Führungs­rollen 37, 38, 39, 40 mit senkrechter Drehachse.Each guide carrier 15, 16 has eight guide rollers 29, 30, 31, 32, 33, 34, 35, 36 with a horizontal axis of rotation and four guide rollers 37, 38, 39, 40 with a vertical axis of rotation.

Der Beschickarm 21 und der Entleerarm 25 setzen sich jeweils aus drei Vierkantrohren 41, 42, 43 und zwei Endstücken 44, 45 zusammen.The loading arm 21 and the emptying arm 25 are each composed of three square tubes 41, 42, 43 and two end pieces 44, 45.

Jeder Verschiebeantrieb 22, 26 besteht aus vier Hubzylindern 46, 47, 48, 49, deren Hublängen 50, 51 52, 53 kürzer als der Ver­schiebeweg 54, 55 des Beschickarms 21 bzw. Entleerarms 25 sind.Each displacement drive 22, 26 consists of four lifting cylinders 46, 47, 48, 49, the stroke lengths 50, 51 52, 53 of which are shorter than the displacement path 54, 55 of the loading arm 21 or emptying arm 25.

Die Hubzylinder 46 bis 49 sind völlig gleich ausgebildete Pneumatikzylinder.The lifting cylinders 46 to 49 are completely identical pneumatic cylinders.

Jedem Verschiebeantrieb 22, 26 sind zwei Andrückvorrich­tungen 56, 57 zum Halten des Beschickarms 21 bzw. Entleerarms 25 in den Endlagen 58, 59, 60, 61 zugeordnet.Each pushing drive 22, 26 is assigned two pressing devices 56, 57 for holding the loading arm 21 or emptying arm 25 in the end positions 58, 59, 60, 61.

Jede Andrückvorrichtung 56, 57 enthält einen Andrückzylin­der 62, 63, einen Andrückhebel 64, 65 und eine Andrück­rolle 66, 67.Each pressure device 56, 57 contains a pressure cylinder 62, 63, a pressure lever 64, 65 and a pressure roller 66, 67.

Zu Beginn des Beschickvorganges werden nacheinander das auf einem Gestell 68 liegende Preßgut 24 von der Greifvorrich­tung 23 ergriffen und die Andrückrolle 67 von dem Endstück 45 des Beschickarms 21 abgeschwenkt.At the beginning of the loading process, the pressed material 24 lying on a frame 68 is gripped by the gripping device 23 and the pressure roller 67 is pivoted away from the end piece 45 of the loading arm 21.

Anschließend wird der Getriebemotor 17 eingeschaltet, der ein Hochheben der Säule 13, des Führungsträgers 15, der Greifvor­richtung 23 und des Preßguts 24 um ein Maß 69 bewirkt.Subsequently, the geared motor 17 is switched on, which causes the column 13, the guide carrier 15, the gripping device 23 and the pressed material 24 to be raised by a dimension 69.

Hiernach wird der Beschickarm 21 durch die Hubzylinder 47, 49 auf der Hublänge 51, 53 von Stillstand auf eine Verschiebege­schwindigkeit V₁ beschleunigt. Wegen der Reibung zwischen dem Führungsträger 15 und dem Beschickarm 21 fällt die Verschiebe­geschwindigkeit V₁ in dem Verschiebebereich 70 geringfügig auf eine Verschiebegeschwindigkeit V₂ ab.Thereafter, the loading arm 21 is accelerated by the lifting cylinders 47, 49 on the stroke length 51, 53 from standstill to a shifting speed V 1. Because of the friction between the guide beam 15 and the loading arm 21, the displacement speed V 1 in the displacement area 70 drops slightly to a displacement speed V 2.

Das Abbremsen des Beschickarms 21 von der Verschiebegeschwindig­keit V₂ bis zum Stillstand bewirken die Hubzylinder 46, 48 auf der Hublänge 50, 52.The braking of the loading arm 21 from the shifting speed V₂ to standstill effect the lifting cylinders 46, 48 on the stroke length 50, 52.

In der Endlage 59 des Beschickarms 21 wird durch Betätigung des Andrückzylinders 62 die Andrückrolle 66 gegen das End­stück 44 gedrückt.In the end position 59 of the loading arm 21, the pressure roller 66 is pressed against the end piece 44 by actuating the pressure cylinder 62.

Sodann werden nacheinander das Preßgut 24 auf das untere Formwerkzeug 7 abgelegt, die Andrückrolle 66 von dem End­stück 44 abgeschwenkt und der Beschickarm 21 durch die Hub­zylinder 46, 48 auf der Hublänge 50, 52 vom Stillstand auf eine Verschiebegeschwindigkeit V₃ beschleunigt.Then the pressed material 24 are placed one after the other on the lower mold 7, the pressure roller 66 is pivoted away from the end piece 44 and the loading arm 21 is accelerated by the lifting cylinders 46, 48 on the stroke length 50, 52 from standstill to a displacement speed V₃.

Der Beschickarm 21, der wegen der Reibungsverhältnisse in dem Verschiebebereich 70 auf eine etwas geringere Verschiebe­geschwindigkeit V₄ abfällt, wird durch die Hubzylinder 47, 49 auf der Hublänge 51, 53 bis zum Stillstand abgebremst.The loading arm 21, which drops to a somewhat lower displacement speed V₄ due to the frictional conditions in the displacement region 70, is braked to a standstill by the lifting cylinders 47, 49 on the stroke length 51, 53.

Der Beschickarm 21 wird nun durch Andrücken der Andrückrolle 67 an das Endstück 45 in einer bestimmten waagerechten Position gehalten.The loading arm 21 is now held in a certain horizontal position by pressing the pressure roller 67 against the end piece 45.

Danach werden die Säule 13, der Führungsträger 15, der Be­schickarm 21 und die Greifvorrichtung 23 um das Maß 69 ab­gesenkt. Die Greifvorrichtung 23 ist in dieser Stellung zum Ergreifen von neuem Preßgut bereit.Then the column 13, the guide bracket 15, the loading arm 21 and the gripping device 23 are lowered by the dimension 69. The gripping device 23 is ready in this position for gripping new material to be pressed.

Sobald der Beschickarm 21 den Bereich der Presse 2 verlassen hat, wird das auf dem unteren Formwerkzeug 7 abgelegte Preß­gut 24 durch Verschieben des oberen Formwerkzeuges 9 nach unten zu einem Formteil verpreßt.As soon as the loading arm 21 has left the area of the press 2, the pressed material 24 placed on the lower mold 7 is pressed downward into a molded part by moving the upper mold 9 downwards.

Das gepreßte Formteil wird dann bei geöffneter Presse 2 mit der Entleervorrichtung 4 von dem unteren Formwerkzeug 7 auf ein Gestell 71 transportiert.The pressed molded part is then transported with the emptying device 4 from the lower mold 7 to a frame 71 with the press 2 open.

Die Gewegungen des Entleerarms 25 laufen in gleicher Weise ab wie beim Beschickarm 21.The movements of the emptying arm 25 proceed in the same way as for the loading arm 21.
