Abstract

The driving device consists of a clamping fixture (2) welded on a support frame (3). A jig saw is supported by a hinge on the clamping fixture and by a support connection (6) on a pressure cylinder (5). The pressure cylinder is connected to the support frame by a hinge. Pressure hoses (7) supply the pressure cylinder and the jig saw with the required power. A pressure reduction valve (4) is used to adjust the pressure to the material and the material thickness.

Description

Die Erfindung dient als kontinuierlicher Druckgeber von elektrisch, pneumatisch oder hydraulisch angetriebenen Stichsägen im Rohrleitungs- und Stahlbau.The invention serves as a continuous pressure transmitter from electrically, pneumatically or hydraulically driven Jigsaws in pipeline and steel construction.

Zur Trennung von Rohrleitungen bzw. Stahlteilen in explo­ sionsgefährdeten Anlagen werden o.g. Stichsägen eingesetzt, bei denen überwiegend der zum schneiden benötigte Anpreß­ druck von Hand aufgegeben wird.For the separation of pipes or steel parts in explo systems at risk of ionization are Jigsaws used, where mainly the pressure required for cutting pressure is applied by hand.

Durch die Erfindung kann dieser Druck maschinell aufgebracht werden, wobei der Anpreßdruck in jeder Schneidstellung ex­ akt derselbe bleibt. Durch Begrenzung des Arbeitsdruckes kann der Vorschub je nach Materialsorte und Materialstärke variabel gewählt werden
Beschreibung der Vorschubeinrichtung in Bezug auf die Zeichnungen beiThis pressure can be applied mechanically by the invention, the contact pressure remaining exactly the same in each cutting position. By limiting the working pressure, the feed can be varied depending on the material type and thickness
Description of the feed device with reference to the drawings

Fig. 1 side view of a jigsaw ( 1 ) mounted on the feed device, the support bracket ( 3 ) by welding to the clamping bracket ( 2 ) in the cutting axis be fastened.

Druckzylinder (5) wird an Stützwinkel (3) und Säge mittels Befestigungsteil (6) in Schnittachse be­ weglich gehalten.Printing cylinder ( 5 ) is held on the support bracket ( 3 ) and saw by means of fastening part ( 6 ) in the cutting axis be movable.

Über Druckleitung (Luft oder Öl) (7) und Druck­ mindererventil (4) wird der Druckzylinder (5) mit dem jeweils nötigen Arbeitsdruck versorgt.The pressure cylinder ( 5 ) is supplied with the required working pressure via pressure line (air or oil) ( 7 ) and pressure reducing valve ( 4 ).
