Description

Die Erfindung bezieht sich auf ein Schutzgehäuse der im Oberbegriff des Anspruchs 1 angegebenen Art.The invention relates to a protective housing of the type specified in the preamble of claim 1.

Ein derartiges Schutzgehäuse ist aus der DE-PS 27 363 bekannt. Dieses bekannte Schutzgehäuse schirmt zwar weitgehend das Trennwerkzeug gegen eine Berührung ab, vermag aber nicht zu verhindern, daß bei einem etwaigen Zerbersten des Trennwerkzeuges dessen Splitter geschoßartig aus der öffnung in den Seitenwänden herausfliegen können.Such a protective housing is known from DE-PS 27 363. This well-known protective housing Although it largely shields the cutting tool against contact, it cannot prevent that if the cutting tool bursts, its splinters projectile out of the opening into the Sidewalls can fly out.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Schutzgehäuse der im Oberbegriff des Anspruchs 1 angegebenen Art so auszubilden, daß es den Sicherheitsanforderungen, die insbesondere an hochtourig angetriebene Trennwerkzeuge gestellt werden, voll genügt, indem neben einem verbesserten Berührungsschutz ein Herumfliegen von Teilen eines zerberstenden Sägeblattes oder einer Trennscheibe verhindert wird.The invention is therefore based on the object of providing a protective housing as described in the preamble of claim 1 specified type in such a way that it meets the safety requirements, in particular at high-speed Driven cutting tools are provided, fully sufficient, in addition to an improved contact protection parts of a breaking saw blade or cutting disc are prevented from flying around.

Die erfindungsgemäße Lösung dieser Aufgabe ist im kennzeichnenden Teil des Anspruchs 1 angegeben.The solution to this problem according to the invention is specified in the characterizing part of claim 1.

Die erfindungsgemäß vorgesehenen Niederhalter dienen vorteilhafterweise einmal zum Spannen des zu trennenden Werkstückes und zum andern gleichzeitig zur vollständigen Abdeckung der öffnungen in denThe hold-down devices provided according to the invention are advantageously used once to clamp the to separating workpiece and, on the other hand, at the same time to completely cover the openings in the

Seitenwänden des Schutzgehäuses.Side walls of the protective housing.

Anspruch 2 kennzeichnet eine zweckmäßige Ausgestaltung der Erfindung.Claim 2 characterizes an expedient embodiment of the invention.

Im folgenden wird die Erfindung anhand der Zeichnung, in der ein Ausführungsbeispiel dargestellt ist, näher erläutert Es zeigtIn the following the invention with reference to the drawing, in which an embodiment is shown, explained in more detail It shows

Fig. 1 den Vertikalschnitt einer Trennmaschine mit dem Schutzgehäuse undFig. 1 shows the vertical section of a cutting machine the protective housing and

Fig.2 die Gesamtansicht der Trennmaschine nach F i g. 1 von der Seite her gesehen.2 shows the general view of the cutting machine according to F i g. 1 seen from the side.

Ein Sockel 1 nimmt eine Auflage 2 für ein stangenförmiges Werkstück 3 und einen Werkzeugständer 4 auf. Dem Werkzeugständer 4 ist höhenverstellbar und schwenkbar ein Aufnahmewinkel 5 zugeordnet, welcher die eigentliche Trennmaschine 6, die mit einem als Kreissägeblatt oder Trennscheibe ausgebildeten Trennwerkzeug 7 bestückt ist, trägtA base 1 takes a support 2 for a rod-shaped workpiece 3 and a tool stand 4 on. A mounting bracket 5 is assigned to the tool stand 4, adjustable in height and pivotable, which is the actual cutting machine 6, which is designed as a circular saw blade or cutting disc Separating tool 7 is equipped, carries

Die Trennmaschine 6 ist über Führungssäulen 8 und Führungszylinder 10 mit dem Aufnahmewinkel 5 verbunden. Der Vor- und Rücklauf des Trennwerkzeuges 7 wird über einen Vorschubzylinder 9 gesteuert. Die die Führungssäulen 8 umgreifenden Führungszylinder 10 sind von einer Konsole 11 aufgenommen, die ihrerseits ein Lager 12 für das Trennwerkzeug 7 und den Antrieb für das Trennwerkzeug aufweist Der Antrieb erfolgt über zwei Zahnscheiben 13 bzw. 13', die über ein flexibles Übertragungselement 14 verbunden sind. Der Antrieb der Zahnscheibe 13' erfolgt direkt von der Achse eines .Motors 15 aus. Auf dem der Zahnscheibe 13 gegenüberliegenden Ende ist der Welle des Lagers 12 das Trennwerkzeug 7 drehfest und auswechselbar zugeordnetThe cutting machine 6 is supported by guide columns 8 and guide cylinders 10 with the mounting bracket 5 tied together. The forward and reverse movement of the cutting tool 7 is controlled by a feed cylinder 9. the the guide columns 8 encompassing guide cylinders 10 are received by a console 11, the in turn has a bearing 12 for the cutting tool 7 and the drive for the cutting tool. The drive takes place via two toothed disks 13 and 13 ', which are connected via a flexible transmission element 14. Of the The toothed disk 13 'is driven directly from the axis of a motor 15. On the toothed disc 13 opposite end of the shaft of the bearing 12, the cutting tool 7 is non-rotatable and exchangeable assigned

Das Trennwerkzeug 7 ist von einem im wesentlichenThe cutting tool 7 is essentially of one type

aus zwei Teilen gebildeten Schutzgehäuse 16 umgeben.Protective housing 16 formed from two parts surrounded.

Gehäusemitte erstreckenden öffnung 17 versehen ist, die vom Trennwerkzeug 7 durchgriffen ist. An den beiden Seitenwänden sind aus nicht näher bezeichneten Führungssäulen und Führungszylindern bestehendeThe opening 17 extending in the middle of the housing is provided through which the cutting tool 7 extends. To the Both side walls are made up of unspecified guide columns and guide cylinders

Führungen angeordnet, die jeweils einen die Öffnung 17 in der Seitenwand abdeckenden Niederhalter 18 aufnehmen, der beim Trennvorgang mit seinem freien Ende auf dem Werkstück 3 abstützbar und gegen die Kraft einer Rückstellfeder (nicht gezeigt) entgegen dem Trennhub verschiebbar gelagert ist.Arranged guides each having a hold-down device 18 covering the opening 17 in the side wall record, which can be supported with its free end on the workpiece 3 during the separation process and against the Force of a return spring (not shown) is mounted displaceably against the separation stroke.

Die Niederhalter 18 sind zweckmäßigerweise jeweils mit einem auswechselbar gehalterten Niederhalterein satz 19 ausgerüstet, der das jeweilige Werkstück 3 formschlüssig übergreiftThe hold-down devices 18 are expediently each provided with an exchangeably held hold-down device Set 19 equipped, which engages over the respective workpiece 3 in a form-fitting manner
