Abstract

The cutter plate (4) inside the pipe is tubular, and immediately behind that is a piston ejector (8) which moves longitudinally to remove cutting waste. The guide outside the pipe is fixed to the cutter plate tube (7) by a horizontal bar (10) and a vertical bar (11), thus forming a rigid U shaped stirrup frame. The guide for the cutter punch (3) has a horizontal bore (6) to receive the work object pipe (1). The pipe is rotatable in stages for slots to be cut radially, and moves horizontally in stages. The cutter punch guide (5) and the cutter plate are fixed to the free ends of the stirrup (10,11,7). ADVANTAGE - The cutter leaves no burr around the slots.

Description

Die Erfindung betrifft eine Vorrichtung zur Herstellung von geschlitzten Filterrohren für Rohrbrunnen aus Rohren mit durchgehenden Wandungen.The invention relates to a device for production of slotted filter tubes for tube wells from tubes with continuous walls.

Bei Rohrbrunnen wird im Bereich der wasserführenden Schicht des Bodens ein Filterrohr eingebaut. Das Filter­ rohr ermöglicht den Eintritt des Wassers aus dem Untergrund in den Brunnen und verhindert gleichzeitig ein Versanden des Brunnens. Es ist ein längeres Rohr, dessen Wandungen über den gesamten Umfang verteilte enge, meist schlitzförmige Durchbrechungen aufweisen, durch die das Wasser in den Brunnen eintreten kann.Pipe wells are in the area of water-bearing Layer of the bottom installed a filter tube. The filter pipe allows water to enter from the Underground in the well while preventing one Sanding the fountain. It's a longer pipe, its Walls distributed over the entire circumference, mostly narrow have slot-shaped openings through which the Water can enter the well.

Die Schlitze werden üblicherweise durch Fräsen herge­ stellt. Das Fräsen hat jedoch den Nachteil, daß auf der Innenseite des Rohres ein dünner Grat stehenbleibt, der stofflich noch mit dem Rohr verbunden ist und praktisch nicht vollständig entfernt werden kann. Dieser Grat ist schädlich, da sich einzelne Stücke von ihm lösen, in die Pumpeinrichtungen gelangen und dort zu Störungen führen können.The slots are usually machined poses. However, milling has the disadvantage that on the A thin ridge remains inside the tube, which is still materially connected to the pipe and practical cannot be removed completely. That ridge is harmful, since individual pieces detach from it, into which Pump devices get there and lead to malfunctions can.

Hier will die Erfindung Abhilfe schaffen. Sie stellt eine Vorrichtung der eingangs erwähnten Art zur Verfügung, mit der eine praktisch gratfreie Schlitzbildung möglich ist.The invention seeks to remedy this. It represents one Device of the type mentioned available, with which enables a practically burr-free slot formation.

Dies wird erfindungsgemäß dadurch verwirklicht, daß die Vorrichtung eine Einrichtung zum Scherschneiden (Stanze) ist mit außerhalb des Rohres angeordneter Führung für den Schneidstempel und einer hiermit fest verbundenen, in das Rohr einführbaren Schneidplatte.This is achieved according to the invention in that the Device a device for shear cutting (punch) is with a guide arranged outside the tube for the Cutting punch and a firmly connected, in the Tube insertable insert.

Der Vorteil des Scherschneidens (Stanzens) ist darin zu sehen, daß kein feiner Grat entsteht, sondern grobe Ab­ fallstücke, die leicht entfernt werden können. Weiterhin ist eine im Vergleich zu dem Fräsen schnellere Bearbeitung der rohrförmigen Werkstücke möglich.The advantage of shear cutting (punching) is there too see that there is no fine ridge, but rough ab cases that can be easily removed. Farther is a faster machining compared to milling of the tubular workpieces possible.

Eine vorteilhafte Ausgestaltung der Erfindung kann darin bestehen, eine Einrichtung zum Entfernen des Schneidab­ falles vorzusehen. Dies kann konstruktiv so verwirklicht sein, daß die Schneidplatte rohrförmig gestaltet ist und in dem Rohrkörper ein längsbeweglicher kolbenartiger Auswerfer für den Schneidabfall angeordnet ist.An advantageous embodiment of the invention can be found therein exist, a device for removing the cutting to be provided. This can be achieved constructively be that the insert is tubular and in the tubular body a longitudinally movable piston-like Ejector for the cutting waste is arranged.

Die feste Verbindung zwischen Schneidstempel und Schneid­ platte kann vorzugsweise so hergestellt werden, indem die Führung für den Schneidstempel einerseits und die Schneid­ platte andererseits am Ende eines steifen, U-förmigen Bügels angeordnet sind. Die Führung für den Schneidstempel kann eine Bohrung zur Aufnahme des Werkstückes aufweisen.The firm connection between cutting punch and cutting plate can preferably be made by the Guide for the cutting punch on the one hand and the cutting plate, on the other hand, at the end of a rigid, U-shaped Brackets are arranged. The guide for the cutting punch can have a hole for receiving the workpiece.

Weiterhin ist die Vorrichtung vorzugsweise so zu gestal­ ten, daß das Werkstück schrittweise in Bezug auf den Bügel bewegbar ist. So ist eine Bearbeitung des Werkstückes auf ganzer Länge und über den gesamten Umfang möglich. Furthermore, the device is preferably so designed ten that the workpiece is gradual with respect to the bracket is movable. So machining of the workpiece is on full length and over the entire circumference possible.

Fig. 4 einen Querschnitt durch das Filterrohr nach Fig. 3. Fig. 4 shows a cross section through the filter tube of FIG. 3.

Die Fig. 3 und 4 lassen erkennen, wie die schlitzförmigen Durchbrechungen 2 bei Filterrohren in typischer Weise gestaltet und angeordnet sind. In Fig. 1 und 2 ist eine erfindungsgemäße Vorrichtung dargestellt, mit der solche Filterrohre aus rohrförmigen Werkstücken 1 durch Scher­ schneiden hergestellt werden können.See Figs. 3 and 4 blank, such as the slit-shaped perforations 2 designed with filter tubes typically and arranged. In Fig. 1 and 2, a device according to the invention is shown, can be prepared intersect with which such filter tubes from tubular workpieces 1 by shear.

Zum Ausschneiden der Schlitze dienen ein Schneidstempel 3 und eine Schneidplatte 4. Die Schneidwerkzeuge sind so ge­ staltet, daß sie drei einzelne, parallele Schneidstempel und entsprechende Gegenstücke in der Schneidplatte aufwei­ sen, so daß mit jedem Arbeitshub jeweils drei schlitzförmige Durchbrechungen 2 hergestellt werden. Zur Aufnahme des Schneidstempels 3 ist eine Führung 5 vorgesehen. Die Füh­ rung 5 weist die eine Bohrung 6 auf, deren Durchmesser geringfügig größer ist als der Außendurchmesser des rohr­ förmigen Werkstückes 1 und die so zur Aufnahme des Werk­ stückes 1 dient. A cutting punch 3 and a cutting plate 4 serve to cut out the slots. The cutting tools are so designed that they have three individual, parallel cutting punches and corresponding counterparts in the insert, so that three slot-shaped openings 2 are produced with each working stroke.
