Description

Die Erfindung :bezieht sieh auf die Herstellung von. Drehsthieberwalzen mit eingegossenen Blechkanälen.The invention: relates to the manufacture of. Rotary valve rolls with cast sheet metal channels.

Es ist bekannt, die Kanäle in der Schieberwa:lze, weiche merklich niedriger oder höher als die übrigen Walzenteilte erwärmt werden, aus Blech zu bilden und an dem Blechkanal eine oder mehrere Dehnungssicken vorzusehen. Der Blechkanal soll eingelötet, gefalzt oder geschweißt werden.It is known that the channels in the slide roller, soften noticeably be heated lower or higher than the rest of the roll parts to form from sheet metal and to provide one or more expansion beads on the sheet metal duct. The sheet metal duct should be soldered in, folded or welded.

Einfacher ist es, die Blechkanäle gemäß der Erfindung beim Gießen der Walzen. mit einzugießen. Demgemäß besteht die Erfindung darin, daß -die Walze in einer Gießform mit in dieser eingesetzten Blechkanälen durch Gießen, insbesondere Schleudergießen, hergestellt wird'. Dabei erhält man einfache Gießformen und erzielt eine vollkommene Verbindung der Kanäle mit dem Walzenkörper. Spannungen störender Höhe entstehen zwischen dem Blechkanal und dem Walzenkörper nicht wegen der Nachgiebigkeit der Dehnungssicken. Ein weiterer Vorteil liegt darin, da.ß die B.lechkanäfe sehr dünnwandig und aus beliebigem, geeignetem,Werkstoff hergestellt sein können.It is easier to use the sheet metal channels according to the invention during casting of the rollers. to pour in. Accordingly, the invention consists in that -the roller in a casting mold with sheet metal channels inserted therein by casting, in particular Centrifugal casting 'is made'. Simple molds are obtained and achieved a perfect connection of the channels with the roller body. Tensions more disruptive Height does not arise between the sheet metal channel and the roller body because of the flexibility the expansion beads. Another advantage is that the B.lechkanäfe very can be thin-walled and made of any suitable material.

Zur Erläuterung der Erfindung dient die Zeichnung.The drawing serves to explain the invention.

Fig. i zeigt eine Schieberwalze z mit geradem Blechkanal i, dessen Dehnungssicke mit 3 bezeichnet ist. Die Verbindung zwischen den Enden des Blechkanals i und dem Außenmantel der Schieberwalze .:2 ist dadurch zustande ,gekommen, d:aß der Blechkanal in die Schleudergießform eingesetzt wurde, worauflhin der Walzenkörper 2 im Schleuderguß gebildet wurde.Fig. I shows a slide roller z with a straight sheet metal channel i, whose Expansion bead is denoted by 3. The connection between the ends of the sheet metal duct i and the outer jacket of the slide roller.: 2 is a result of this, d: aß the sheet metal channel was inserted into the centrifugal casting mold, whereupon the roller body 2 was formed by centrifugal casting.

Nach dem gleichen Verfahren können auch anders geformte Blechkanäle eingegossen werden, wie beispielsweise die Fig. 2. und 3 erläutern.Different shaped sheet metal ducts can also be produced using the same procedure be poured, as for example FIGS. 2 and 3 explain.

In.Fig. 2 ist der Blechkanal q. schräg eingesetzt und. weist eine Dehnungssicke 5 auf.In Fig. 2 is the sheet metal channel q. inserted at an angle and. has a Expansion bead 5.

In Fig. 3 liegt im Innern des Schieberwalzenkörpers 6 ein Blechkanal 7, welcher eine Krümmung von go° aufweist, so daß die Kanalrichtung aus der Radialrichtung in die Axialrichtung' der Walze überleitet. Die Dehnun.gssicke ist hierbei mit 8 bezeichnet.In Fig. 3 is located in the interior of the slide roller body 6, a sheet metal channel 7, which has a curvature of go °, so that the channel direction out of the radial direction transferred in the axial direction 'of the roller. The expansion bead is here with 8 designated.
