Vorrichtung zum Einschleifen von SchrägschliffenDevice for grinding in bevel cuts
Die Erfindung bezieht sich auf eine Vorrichtung zum Einschleifen von Schrägschliffen in konische Wände runder Schnittplattendurchbrüche.The invention relates to a device for grinding bevel cuts into conical walls of round cut-through openings.
5 Durchbrüche in Schnittplatten sind zum leichteren herausfallen der Abfallteile und der gefertigten Teile konisch geformt. Zur Verhinderung des Herausreißens von Abfaii-oder Fertigungsteilen aus Schnittplattendurchbrüchen in Stanzautomaten und Exzenterpressen werden sämtliche Durch-—^ 10 brüche einer Schnittplatte außerdem mit zwei gegenüber- liegenden Schrägschliffen versehen, die in einem bestimmten Winkel zur Stanzrichtung angeordnet sind (Patentanmeldung P 33 29 429.1).5 Openings in cut plates are conical to make it easier for the waste parts and the manufactured parts to fall out. To prevent tearing out of cut-out or production parts from cut-out openings in punching presses and eccentric presses, all openings of a cut plate are also provided with two opposing bevel cuts, which are arranged at a certain angle to the punching direction (patent application P 33 29 429.1) .
Der Erfindung liegt die Aufgabe zugrunde, zum exakten Ein-15 schleifen derartiger Schrägschliffe in runden Durchbrüchen mit Durchmessern größer als 0,8 mm eine Vorrichtung zu schaffen, die im Winkel der Konizität der Schnittplattendurchbrüche bestimmte Winkel der Schrägschliffe in den runden Durchbruchwandungen erzielt.The invention has for its object to create a device for the precise grinding of bevel cuts in round openings with diameters greater than 0.8 mm, which achieves certain angles of the bevel cuts in the round opening walls in the angle of the taper of the cutting plate openings.
20 Diese Aufgabe ist durch die im Kennzeichnungstei1 des ersten Patentanspruches dargelegte Erfindung gelöst.20 This object is achieved by the invention set out in characterizing part 1 of the first claim.

Die Vorrichtung zum Einschleifen von Schrägschliffen, in den weiteren Ausführungen als Vorrichtung bezeichnet, ist an einer Koordinaten-Schleifmaschine 10 befestigt. Die Vorrichtung wird gebildet aus einer Steuereinrichtung 11, 5 einer Einstellvorrichtung 12 für den Winkel B der Schrägschliffe 20, 21 in den runden Schnittplattendurchbrüchen und einer Führungseinrichtung 13 für die Schl eifSpindel-aufnahme 14.The device for grinding in bevel cuts, referred to in the following as a device, is attached to a coordinate grinding machine 10. The device is formed from a control device 11, 5, an adjusting device 12 for the angle B of the bevel cuts 20, 21 in the round cutting plate openings and a guide device 13 for the grinding spindle receptacle 14.
Der Winkel A der Konizität der Durchbrüche wird direkt an 10 der Schleifspindelaufnähme 14 durch deren Schwenken einge-stellt, während der Winkel B der Schrägschliffe 20, 21 abhängig von der Größe des Durchbruchdurchmessers mittels der Einstellvorrichtung 12 festgelegt wird.The angle A of the taper of the openings is set directly at 10 of the grinding spindle receptacles 14 by pivoting them, while the angle B of the bevel cuts 20, 21 is determined by the adjusting device 12 depending on the size of the opening diameter.
Die Einstellvorrichtung 12 ist mit einer Führungseinrichtung 13 13 gekoppelt. Diese Führungseinrichtung 13 besteht im wesent lichen aus einem Druckluftzylinder 15, der über Verbindungsstücke einen Hebel 16 in einer horizontal liegenden Nut 17 führt. Der Hebel 16 ist starr mit der Schleifspindelaufnahme 14 verbunden. Wird nun durch nicht dargestellte elektro-20 pneumatische Ventile der Druckluft Zylinder 15 in Bewegung versetzt, so wird die Schl eifspindelaufnähme 14 nach zwei Seiten um je einen Winkel von 60° gedreht, indem der Hebel O . 16 in Pfei1richtung in der horizontal liegenden Nut 17 vor und zurück bewegt wird.The adjusting device 12 is coupled to a guide device 13 13. This guide device 13 consists in wesent union of a compressed air cylinder 15 which leads a lever 16 in a horizontally lying groove 17 via connecting pieces. The lever 16 is rigidly connected to the grinding spindle receptacle 14. If cylinder 15 is now set in motion by electro-20 pneumatic valves (not shown) of the compressed air, the grinding spindle receptacle 14 is rotated on both sides by an angle of 60 ° by lever O. 16 is moved back and forth in the direction of the arrow in the horizontally lying groove 17.
25 Diese Drehbewegung bewirkt ein Senken des Diamant-25 This rotary movement causes the diamond
Schlei fstiftes 18 nach unten parallel zum eingestellten Winkel A der Konizität. Ferner bewegt sich der Diamant-Schleifstift 1B um den Winkel B parallel an der Innenwanounc. des runden Durchbruches 19 entlang und schleift einen gleicn-30 bleibend tiefen Schrägschliff 20 bzw. 21 ein. Dieser Vorgang ist entsprechend der gewünschten Schleiftiefe mehrmals zu wiederholen.Grinding pin 18 downwards parallel to the set angle A of the taper. Further, the diamond grinding pin 1B moves parallel to the inner wall by the angle B. along the round opening 19 and grinds a gleicn-30 permanent deep bevel cut 20 or 21. This process must be repeated several times according to the desired grinding depth.
