Abstract

The arrangement is especially used for machining the contours of spoons and consists of a grinding or polishing stone (4) which is moved by an electro-hydraulic mechanism along the contour of the workpiece. The workpiece (7) is clamped in a holder (5, 6). The grinding stone is brought by a servo cylinder (1) against the workpiece at a point. The cylinder movement is controlled to exert the required grinding pressure. The movement along the workpiece is controlled by a servo cylinder (2) which acts at right angles to the first cylinder. The servo cylinders act against a mounting block (3) on which the grinding wheel is mounted.

Description

Verfahren zum Kantenbearbeiten, insbesondere fürEdge processing method, especially for

Besteckfe rtiun Die Erfindung betrifft ein Verfahren zum Kantenbearbeiten profilierter werkstücke mit gekrümmten Oberflächen, insbesondere von Besteckteilen, vorzugsweise auf Schleif- und Foliermaschinen.Cutlery production The invention relates to a method for edging profiled workpieces with curved surfaces, especially cutlery, preferably on grinding and foiling machines.

Es ist bekannt, die Kantenbearbeitung von insbesondere Besteckteilen manuell oder auch maschinell in Vorrichtungen durchzuführen, wobei die Besteckteile zwischen ein oder zwei Bandaggregaten hindurchgeführt werden. Die Führung der die Schleifbänder an die zu bearbeitenden Besteckteile andrückenden Kontakt rollen übernehmen dabei schablonengesteuerte Tastrollen.It is known to work the edges of cutlery in particular to be carried out manually or by machine in devices, with the cutlery be passed between one or two belt units. The leadership of the Abrasive belts take over the contact with the cutlery to be processed template-controlled feeler rollers.

Die Handarbeit erfordert geübte Fachkräfte und bedingt bei geringen Stückzahlen hohe Herstellungskosten.The manual work requires skilled workers and, to a certain extent, low High production costs.

Die bei der maschinellen Bearbeitung erforderlichen Steuereinrichtungen und komplizierten Werkstückaufnahmen mit längsverschieblichen Schlitten und Drehteller mit eigenem Antrieb bilden in Verbindung mit ihrem System von Steuernocken wesentliche Nachteile beim Wechsel der Werkstückserie durch die damit bedingten Einstelloperationen. Die mechanische Abtastung und die damit verbundene umfangreiche getriebetechnische Ausbildung zur Führung der zu bearbeitenden Werkstücke führt unter den Bedingungen der Schleifwirkung und des damit verbundenen hohen Verschmutzungsgrades zu starken Verschleißerscheinungen an den gesamten Steuerelementen und läßt damit eine maschinelle Kantenbearbeitung äußerst störanfällig werden.The control devices required for machining and complicated workpiece holders with longitudinally displaceable slides and turntables with their own drive are essential in connection with their system of control cams Disadvantages when changing the workpiece series due to the associated setting operations. The mechanical scanning and the associated extensive transmission technology Training to guide the workpieces to be machined leads under the conditions the abrasive effect and the associated high degree of soiling Signs of wear and tear on the entire control elements and thus leaves a machine Edge processing can be extremely prone to failure.

Zweck der Erfindung ist es, die aufgezeigten Nachteile der schablonengesteuerten Kantenbearbeitung profilierter Werkstücke mit gekrümmten Oberflächen weitestgehend zu beseitigen und die Störanfälligkeit extrem zu verringern, Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu entwickeln, das die maschinelle Kantenbearbeitung profilierter Werkstücke mit gekrümmten Oberflächen, insbesondere von Besteckteilen, auf automatisch arbeitenden Anlagen, insbesondere auf Transferstraßen, ermöglicht. Durch die Anwendung des Verfahrens soll es möglich werden, die ebenfalls zur Patenterteilung angemeldete Schleif- und Poliermaschine (P 24 28 798.7) auch für die Kantenbearbeitung einzusetzen.The purpose of the invention is to address the disadvantages of the template-controlled Edge processing of profiled workpieces with curved surfaces as far as possible to eliminate and extremely reduce the susceptibility to failure, Of the The invention is based on the object of developing a method that the machine Edging of profiled workpieces with curved surfaces, in particular of cutlery on automatically operating systems, especially on transfer lines, enables. By using the method it should be possible to do that as well Grinding and polishing machine (P 24 28 798.7) registered for a patent as well to be used for edge processing.

Es wurde gefunden, daß die bereits aus der Patentanmeldung P 24 28 798.7 bekannte elektrohydraulische Servoregoleinrichtung zur Anpassung der Arbeitsspindeln an die Werkstückform auch für die Kantenbearbeitung von Bosteckteilen genutzt werden kann, wenn sie durch eine weitere gleiche Einrichtung ergänzt und durch die wechselseitige Nutzung beider Einrichtungen für Vorschub und Regelung eine in zwei Ebenen wirkende Schleifwalzenandrückung erreicht wird, wodurch ein Umfangsschleifen der Umrißkante länglicher Werkstücke, z. B. von gesamten Besteckstielendenkonturen, über 180 ° hinweg möglich ist.It has been found that the patent application P 24 28 798.7 known electro-hydraulic servo regulating device for adapting the work spindles to the shape of the workpiece can also be used for edge processing of corner parts can, if they are supplemented by another identical facility and by the reciprocal Use of both devices for feed and control, one acting on two levels Grinding roller pressure is achieved, whereby a peripheral grinding of the contour edge elongated workpieces, e.g. B. of entire cutlery handle end contours, over 180 ° away is possible.

Die Erfindung soll nachstehend an einem Ausführungsbeispiel näher erläutert werden. Die zugehörige Zeichnung zeigt eine schematische Darstellung der in Anwendung des erfindungegenäßen Verfahrens möglichen Bewegungsabläufe in einer Schleif-und Poliermaschine gemäß Patentanmeldung P 24 28 798.7 zur Bearbeitung von Stielenden von Besteckteilen.The invention is to be described in more detail below using an exemplary embodiment explained. The accompanying drawing shows a schematic representation of the in application of the method according to the invention possible movement sequences in one Grinding and polishing machine according to patent application P 24 28 798.7 for processing Handle ends of cutlery items.

Beginnend im Ausgangspunkt A wird die Walzenaufnahme 3 mit der Schleif- und Polierwalze 4 durch den Servozylinder 1 an das in der Werkstückaufnahme 5,6 fest verspannte Werkstück 7 herangeführt und zum Erreichen der erforderlichen Schleif-und Polierintensität vertikal geregelt. Die Steuerung des Vorschubes erfolgt dabei horizontal durch den Servozylinder 2.Beginning at starting point A, the roll holder 3 with the grinding and polishing roller 4 through the servo cylinder 1 to the one in the workpiece holder 5,6 firmly clamped workpiece 7 brought up and to achieve the required grinding and Polishing intensity regulated vertically. The feed is controlled horizontally through the servo cylinder 2.

Beim Erreichen des Stielendes des Werkstückes 7 übernimmt an einem einstellbaren Schaltpunkt der Servozylinder 1 den weiteren Vorschub der Schleif- und Polierwalze in vertikaler Richtung, während der Servozylinder 2 jetzt die Regelfunktion in horizontaler Richtung ausführt. Ein weiterer einstellbarer Schaltpunkt kehrt nach dem Passieren des Stielendes die Steuer-und Regelfunktion der Servozylinder 1,2 erneut um und bringt die Polier- und Schleifwalze an der gegenüberliegenden Seite des Werkstückes 7 im Ausgangspunkt B in analoger Weise zum Eingriff.Upon reaching the end of the handle of the workpiece 7 takes over at one adjustable switching point of the servo cylinder 1 the further feed of the grinding and polishing roller in the vertical direction, while the servo cylinder 2 now has the control function executes in the horizontal direction. Another adjustable switching point returns After passing the end of the handle, the control and regulation function of the servo cylinder 1.2 again and bring the polishing and sanding roller to the opposite one Side of the workpiece 7 in the starting point B in an analogous manner to the engagement.
