Abstract
Description
Die Erfindung betrifft eine Schneidkopfführung zur Schrägstellung des Schneidkopfes von Wasserstrahlschneidmaschinen zur Schnittschrägenkompensation.The invention relates to a cutting head guide for the inclination of the cutting head of Water jet cutting machines for cutting bevel compensation.
Bekannt aus dem Stand der Technik sind Halterungen für den Schneidkopf, bei denen der Schneidkopf im Achsen drehbeweglich gelagert ist.Known from the prior art are holders for the cutting head, in which the cutting head is mounted rotatably in the axes.
Beim Schneiden von flächigen Werkstücken mit einem Wasserstrahl ist der vom Schneidstrahl erzeugte Schneidspalt auf der Eintrittseite des Schneidstrahles meist schmaler als auf der Austrittseite. Der Querschnitt des Schneidspaltes ist trapezförmig mit einem Böschungswinkel der Schnittflächen je nach Material und Schnittgeschwindigkeit hauptsächlich bis 6° (und mehr). Diese Schnittschräge ist bei Präzisionsteilen unerwünscht. Es ist eine Nachbearbeitung notwendig, um eine rechtwinklig zur Oberfläche stehende Schnittfläche zu erhalten.When cutting flat workpieces with a water jet, that of the cutting jet produced cutting gap on the entry side of the cutting jet usually narrower than on the exit side. The cross section of the cutting gap is trapezoidal with a slope angle the cut surfaces depending on the material and cutting speed mainly up to 6 ° (and more). This chamfer is undesirable in precision parts. It is a post-processing necessary to obtain a perpendicular to the surface cutting surface.
Bei geraden Schnitten in eine Richtung kann durch manuelles Schrägstellen des Schneidkopfes um einen dem Auftreffpunkt des Schneidstrahles auf der Werkstückoberfläche entsprechenden Drehpunkt um einen dem Böschungswinkel entsprechenden Winkel Präzisionsteil hin die Schnittschräge kompensiert werden.For straight cuts in one direction can be made by manually tilting the cutting head a corresponding to the point of impact of the cutting beam on the workpiece surface Fulcrum around an angle corresponding to the angle of repose precision part towards the cutting slope are compensated.
Bei einem Richtungswechsel ist der Schneidkopf erneut manuell einzustellen, wozu die Maschine angehalten werden muss, so dass eine Nachbearbeitung des Fertigteiles ökonomischer ist.When changing direction, the cutting head must be manually adjusted again, including the machine must be stopped, so that a post-processing of the finished part of economic is.
Ziel und Aufgabe der Erfindung ist es, eine Schneidkopfführung zur Schrägstellung des Schneidkopfes von Wasserstrahlschneidmaschinen zur programmgesteuerten Schnittschrägenkompensation an beliebiggestalteten Fertigteilen zu finden.The aim and the object of the invention is to provide a cutting head guide for tilting the Cutting head of water jet cutting machines for program-controlled cutting bevel compensation to find any shape prefabricated parts.
Die Lösung der Aufgabe ist Gegenstand des ersten Anspruchs. Weitere zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand der weiteren Unteransprüche.The solution of the problem is the subject of the first claim. Further expedient embodiments The invention are the subject of the other subclaims.
Die Schneidkopfführung zur Schrägstellung des Schneidkopfes zur Schneidschrägenkompensation beim Wasserstrahlschneiden besteht aus einer das den Schneidkopf tragende Kollimationsrohr oder den Schneidkopf selbst einspannenden, den Schneidkopf haltenden und führenden Fassung. Die Fassung wird über Streben, die die Kanten eines auf der Kleinfläche stehenden Pyramidenstumpfes mit gleichseitiger Grundfläche bilden, mit einer fest an dem Schneidkopfantrieb gelagerten Grundplatte verbunden. An der Fassung greifen Steuerkräfte zur Schrägstellung des Schneidkopfes an. Die Streben sind mit Biegegelenken sowohl an der Grundplatte als auch an der Fassung befestigt. Sie können auch mit Kreuzgelenken befestigt sein. Die Mittelachsen der Streben schneiden sich gegenseitig in einem Punkt auf der Schneidstrahlachse, der in der Nähe der Schneidstrahlaustrittsöffnung der Fokussierdüse bzw. in der Nähe des Auftreffpunktes des Schneidstrahls auf dem Werkstück liegt.The cutting head guide for tilting the cutting head for Schneidschrägenkompensation when water jet cutting consists of a carrying the cutting head Collimating tube or the cutting head self-clamping, holding the cutting head and leading version. The socket is about struts that are the edges of one on the small area standing truncated pyramid form an equilateral base, with a firm on connected to the cutting head drive base plate connected. On the frame control forces for tilting the cutting head. The struts are with flexures both attached to the base plate as well as to the socket. You can also use universal joints be attached. The central axes of the struts intersect each other in one point the cutting beam axis, which is in the vicinity of the cutting jet outlet opening of the focusing nozzle or in the vicinity of the point of impact of the cutting beam on the workpiece.
Durch die Bewegung des Schneidkopfantriebes wird der Schneidkopf in der gewünschten Schnittrichtung geführt. Bei senkrechter Stellung des Schneidkopfes hat der Schneidspalt einen trapezförmigen Querschnitt mit unter gleichem Böschungswinkel schräg stehenden Schnittflächen. Um eine senkrecht zur Oberfläche des Präzisionsteils stehende Schnittfläche zu erhalten, muss der Schneidkopf um den Böschungswinkel der Schnittfläche zum Präzisionsteils hin geneigt werden. Dazu wird durch die Steuerkräfte die Fassung seitlich verschoben. Durch die mit den Gelenken befestigten Streben wird die Fassung in kleinen Winkelbereich bis ca. 6° so geneigt, dass der Schneidkopf schräg steht, ohne daß die Schneidstrahlaustrittsöffnung der Fokussierdüse und damit der Auftreffpunkt des Schneidstrahls auf dem Werkstück die Schneidstrahlachse bezogen auf die Ruhestellung des Schneidkopfes verlässt. Da der Angriff der Steuerkräfte gezielt von allen Seiten an der Fassung erfolgen kann, erfolgt ein dem Schnittverlauf angepasstes programmierbares Schrägstellen des Schneidkopfes, so daß ein Schneiden von Kreisbögen oder Vollkreisen möglich ist. Das durch das Schrägstellen des Schneidkopfes erfolgende Anheben des Schneidkopfes wird durch Nachstellen der Z-Achse ausgeglichen.Due to the movement of the cutting head drive, the cutting head is in the desired Cutting direction led. In the vertical position of the cutting head of the cutting gap a trapezoidal cross-section with inclined at the same slope angle Sectional areas. Around a perpendicular to the surface of the precision part cutting surface To obtain the cutting head must be about the angle of repose of the cut surface to the precision part be inclined towards. For this purpose, the socket is moved laterally by the control forces. Due to the struts attached to the joints, the socket is in a small angular range tilted to about 6 ° so that the cutting head is inclined without the cutting jet outlet opening the Fokussierdüse and thus the point of impact of the cutting beam the workpiece, the cutting beam axis relative to the rest position of the cutting head leaves. Since the attack of the control forces are made deliberately from all sides of the socket can be done, the cutting profile adapted programmable tilting the Cutting head, so that a cutting of circular arcs or full circles is possible. The lifting the cutting head by tilting the cutting head compensated by adjusting the Z axis.
Die Erfindung soll nachstehend an Hand eines Ausführungsbeispiels näher erläutert werden. Die zugehörige Zeichnung zeigt eine stilisierte Seitenansicht der Schneidkopfführung zur Schnittschrägenkompensation.The invention will be explained in more detail below with reference to an embodiment. The accompanying drawing shows a stylized side view of the cutting head guide to Section Angular compensation.
Ein Schneidkopf 1 ist an einem frei beweglichen Kollimationsrohr 2 befestigt. Das Kollimationsrohr
2 ist in einer Fassung 3 gehaltert. Die Fassung 3 ist über vier Streben 4 , die die
Kanten eines umgedrehten Pyramidenstumpfes mit quadratischer Grundfläche bilden, mit
einer Grundplatte 5 verbunden. Die Grundplatte 5 ist fest mit dem nicht dargestellten Antrieb
des Schneidkopfes 1 verbunden. Jede Strebe 4 ist über ein Biegegelenk 6 an jedem Ende
sowohl mit der Fassung 3 als auch mit der Grundplatte 5 verbunden. Die Mittelachsen 7 der
Streben 4 schneiden sich in der Ruhestellung auf der Schneidstrahlachse 8 in der Nähe der
Austrittsöffnung der Fokussierdüse 9. Durch die in Pfeilrichtung wirkenden Steuerkräfte auf
die Fassung 3 wird diese durch die Streben 4 mit ihren Biegegelenken 6 so gekippt, dass der
Schneidkopf 1 um kleine Winkel bis 6° schräg gestellt wird, ohne dass die Austrittsöffnung
der Fokussierdüse 9 die Schneidstrahlachse 8 der Ruhestellung des Schneidkopfes 1 verläßt. A
