Description

Bei. Schiebern; insbesondere solchen, die für höhe Drücke und Temperaturen bestimmt und aus diesem Grunde ohne Flansche- eingeschweißt sind, ergibt sich bisweilen die Notwendigkeit einer- Nacharbeitung,der Abdichtungsflächen. Dies bereitet bei den Schieberplatten keine Schwierigkeiten, da diese ausgebaut und in der Werkstatt bearbeitet werden können. Anders bei .den. am Gehäuse des Schiebers befindlichen Abdichtungsflächen a (Abb. r und 2): Infolge der meist gedrängten Bauart und-,der hohen Ansprüche an die Oberflächengenauigkeit ist es sehr schwierig, mit den. bekannten Nacharbeitungsgeräten, .die sich unmittelbar auf die Dichtungsflächen des Schiebers abstützen, eine ausreichende Genauigkeit zu erreichen. Eine Voraussetzung für eine Nacharbeit der Abdichtungsbächen bzw. der Auflageflächen für auswechselbare Sitzringe ist die Schaffung einer möglichst freien Arbeitsleiste: Sehr viele Scheberkonstruktionen weisen auf Grund der formgebungsmäßigen Notwendigkeit derartige Möglichkeiten von vornherein auf.At. Sliders; especially those for high pressures and temperatures determined and, for this reason, welded in without flanges, sometimes arises the need for reworking of the sealing surfaces. This prepares for the slide plates no problems, as they are removed and in the workshop can be edited. Not so with. located on the housing of the slide Sealing surfaces a (Fig. R and 2): As a result of the mostly compact design and-, the high demands on the surface accuracy, it is very difficult with the. known Reworking devices,. Which are directly on the sealing surfaces of the slide support to achieve sufficient accuracy. A requirement for a Reworking of the sealing brooks or the contact surfaces for replaceable seat rings is the creation of a work bar that is as free as possible: a lot of Scheber constructions have such possibilities due to the shaping necessity in advance.

Es wurde nun gefunden, daß man Geräte zum Nacharbeiten b (Abb. r) der Abdichtungs- oder Auflageflächen für Sitzringe besonders vorteilhaft ansetzen kann, wenn man für diese Werkzeuge besondere Anlageflächen öder Zentrierungen c (Abb. 2) schafft, die unabhängig von den Abdichtungsflächen sind. Durch diese besonderen, unabhängigen Werkzeugaufnahmen ist eine einwandfreie Einspannung des Werkzeuges gegeben, und die Arbeitsgenauigkeit ist nicht von den Oberflächen bzw. der Lage der Abdichtungsflächen abhängig. Gleichzeitig kann man außer den Vorkehrungen zur Aufnahme von Werkzeugen auch weitere Kanten oder Anlagen, z. B. e (Abb. 2), anbringen, welche es erlauben, mit besonderen Meßgeräten oder Leeren, z. B. d (Abb. 2), die Größe und Genauigkeit der Nacharbeit nachzuprüfen. Diese Notwendigkeit ergibt sich besonders dann, wenn die Einbauteile des Schiebers auf Grund ihrer Konstruktion eine einw andfreie mittige Lage erfordern.It has now been found that devices for reworking b (Fig. R) It is particularly advantageous to use the sealing or contact surfaces for seat rings can, if you have special contact surfaces or centering for these tools c (Fig. 2) that are independent of the sealing surfaces. Through this special, independent tool holders means that the tool is properly clamped given, and the accuracy of the work is not dependent on the surfaces or the position depending on the sealing surfaces. At the same time you can except the precautions for Acceptance of tools and other edges or systems, e.g. B. e (Fig. 2), attach, which allow, with special measuring devices or empties, z. B. d (Fig. 2), the Verify the size and accuracy of the rework. This need arises especially if the built-in parts of the slide due to their construction require a flawless central position.
