Description
Infolge der starken Korrosion (Rostnarben von o,i bis 0,3 mm Tiefe) der guß-eisernen Schieberrostflächen, besonders in Hik-Steuerventilen, ist das bisherige Aufarbeitungsverfahren (Nachläppen) mit Feilen aus Resistinbronze, Hartkupfer oder Grauguß nicht möglich oder mit tagelanger Arbeit verbunden.As a result of the strong corrosion (rust scars from 0.1 to 0.3 mm deep) of the cast iron slide grate surfaces, especially in Hik control valves, the previous refurbishing process (re-lapping) with files made of resistin bronze, hard copper or gray cast iron is not possible or takes days of work tied together.
Diese Nachteile beseitigt die Erfindung. Sie besteht darin, daß, abweichend von den obenerwähnten Verfahren mit Hand, die Korrektur der Schieberroste in bezug auf Ebenheit und Oberflächengüte durch eine mechanische Vorrichtung vorgenommen wird, die ein mit einem Keil einstellbares Räumwerkzeug besitzt. Die Abbildung zeigt das Gerät im Schnitt.The invention overcomes these disadvantages. It consists in that, deviating of the above-mentioned procedures by hand, the correction of the sliding grates in relation to made for evenness and surface quality by a mechanical device which has a broach that can be adjusted with a wedge. The figure shows the device on average.
Das Gerät besteht aus einem Räumwerkzeug A mit Werkstückträger B, dein Keil C mit den Stellschrauben D und E und der Abstandbuchse F.The device consists of a broaching tool A with workpiece carrier B, your wedge C with the adjusting screws D and E and the spacer sleeve F.
Das Räumverfahren wird folgendermaßen durchgeführt: Das Steuerventilgehäuse wird auf den Werkstückträger bis zum Anschlag der Kolbenkammerseite des Steuerventils an die Abstandbuchse F geschoben. Hierbei i-st das Räumwerkzeug A noch abgelegt, und Keil C ist zurückgezogen. Nun wird das Räumwerkzeug in die Nut des Steuerventils eingeführt und mittels des Keiles C zum Schnitt gegen den Schieberrost des Steuerventils gedrückt. Der Keil wird jetzt durch die Stellschrauben D und E festgelegt. Mit einer an sich bekannten Einrichtung, entweder einer hydraulischen oder durch Spindel angetriebenen Einrichtung, wird das Räumwerkzeug .A durch die Nut des Steuerventils gezogen. Bei diesem Vorgang nehmen die Schneiden rund o, i mm Dicke von dem Schieberrost ab. Nach Bedarf kann dieser Vorgang wiederholt werden unter Nachstellen des Keiles C und erneutem Festlegen durch die Stellschrauben D und E. Damit ist der Vorgang beendet, und das Steuerventil kann abgenommen werden.The broaching procedure is carried out as follows: The control valve housing is on the workpiece carrier up to the stop on the piston chamber side of the control valve pushed to the spacer sleeve F. Here the broaching tool A is still put down, and wedge C is withdrawn. Now the broach is in the groove of the control valve introduced and by means of the wedge C to cut against the slide grate of the control valve pressed. The wedge is now set by adjusting screws D and E. With a known device, either hydraulic or driven by a spindle Device, the broach .A is pulled through the groove of the control valve. at During this process, the cutting edges are about 0.1 mm thick from the sliding grate. If necessary, this process can be repeated while readjusting the wedge C and setting it again with adjusting screws D and E. This ends the process, and the control valve can be removed.
Zunächst ist die Vorrichtung und das Verfahren mit Erfolg bei der Hildebrand-Knorr-Druckluftbremse angewandt worden. Die Vorrichtung eignet sich aber auch zum Räumen der Schieberroste bei anderen Druckluftbremsbauarten mit entsprechend anderen Abmessungen.First, the apparatus and method have proven successful in the Hildebrand-Knorr air brake has been used. However, the device is suitable also for clearing the sliding grates with other types of air brakes with corresponding other dimensions.
