Abstract

The invention relates to a method for producing a flat key whose key shaft is provided on at least one face with profiles that serve as main and/or supplementary guiding grooves and/or with certain features. One or both faces are provided with base profiles (6), and a first undercut (1) is produced in one or more of these base profiles (6) the direction axis of which is different from the direction axis of the corresponding base profile (6). At least one base profile (6) that has a first undercut (1) is provided with a second undercut (4) which extends from the first undercut (1) and whose direction axis is different from the direction axis of the first undercut (1) and equal or different from the direction axis of the base profile (6).

Description

Verfahren zur Herstellung eines FlachschlüsselsMethod of making a flat key
Die Erfindung betrifft ein Verfahren zur Herstellung eines Flachschlüssels, dessen Schlüsselschaft an mindestens einer der Seitenflächen Profile als Haupt- und/oder Nebenführungsrippen und/oder Merkmale aufweist.The invention relates to a method for producing a flat key, the key shaft of which has profiles as main and / or secondary guide ribs and / or features on at least one of the side surfaces.
Bei Flachschlüsseln dieser Art werden die Profile durch Fräsen, Stoßen, Räumen oder Ziehen hergestellt, wobei bei entsprechender Ausbildung der Werkzeugsätze gleichzeitig die Bearbeitung beider Seitenflächen erfolgen kann.In the case of flat keys of this type, the profiles are produced by milling, shaping, broaching or pulling, it being possible for both side surfaces to be machined simultaneously if the tool sets are designed accordingly.
Eine Grundintension bei der Schlüsselherstellung überhaupt ist die Erhöhung der Variationen bzw. der Sicherheit gegen Nachahmungen.A basic intensity in key production in general is the increase of the variations or the security against counterfeiting.
Aufgabe der Erfindung ist es, ein Verfahren zur Herstellung von Flachschlüsseln zu schaffen, mit dem die Sicherheit gegen die Herstellung von Nachschlüsseln dadurch erhöht wird, dass nur noch eine werksseitige Herstellung möglich ist.The object of the invention is to provide a method for the production of flat keys with which the security against the production of duplicate keys is increased by the fact that only a factory production is possible.
Gelöst wird diese Aufgabe erfindungsgemäß bei einem Verfahren zur Herstellung eines Flachschlüssels, dessen Schlüsselschaft an mindestens einer der Seitenflächen Profilierungen als Haupt- und/oder Nebenführungsrippen und/oder Merkmale aufweist, dadurch,This object is achieved according to the invention in a method for producing a flat key, the key shaft of which has profilings as main and / or secondary guide ribs and / or features on at least one of the side surfaces,
- dass an einer oder beiden Seitenflächen Grundprofile eingebracht werden,- that basic profiles are introduced on one or both side surfaces,
- dass in einem oder mehreren dieser Grundprofile eine erste Hinterschneidung erzeugt wird, deren Richtungsachse ungleich zu der Richtungsachse des entsprechenden Grundprofils ist,a first undercut is created in one or more of these basic profiles, the direction axis of which is unequal to the direction axis of the corresponding basic profile,
- dass in wenigstens eines der eine erste Hinterschneidung aufweisenden Grundprofile eine von der ersten Hinterschneidung ausgehende zweite Hinterschneidung eingebracht wird, deren Richtungsachse ungleich der Richtungsachse der ersten Hinterschneidung und gleich oder ungleich der Richtungsachse des Grundprofils ist. Ausgestaltungen ergeben sich aus den Unteransprüchen- That in at least one of the basic undercuts having a first undercut a second undercut starting from the first undercut is introduced, the direction axis of which is not equal to the direction axis of the first undercut and is equal to or different from the direction axis of the basic profile. Refinements result from the subclaims
Kerngedanke der Erfindung ist, dass die Variationen durch die Erzeugung von zwei ineinanderübergehenden Hinterschneidungen erhöht werden kann, wobei es wesentlich ist, dass je nach Art der Hinterschneidung nur bestimmte Werkzeugsätze oder Arbeitsverfahren angewendet werden können. Dies erschwert dann die Nachahmung. Die Form der Hinterschneidungen selbst ist dabei nicht entscheidend.The main idea of the invention is that the variations can be increased by producing two undercuts which merge into one another, it being essential that, depending on the type of undercut, only certain tool sets or working methods can be used. This then makes imitation difficult. The shape of the undercuts themselves is not critical.
Dies soll nachfolgend an den Zeichnungen erläutert werden, wobei in den Figuren jeweils der Schlüsselschaft vereinfacht in Querschnitt dargestellt ist.This will be explained in the following in the drawings, the key shank in each case being shown in simplified form in cross section in the figures.
In Figur 5 ist ein übliches Schlüsselprofil mit Grundprofilen 6 auf beiden Seitenflächen des Flachschlüssels dargestellt. Diese können beispielsweise durch Fräsen erzeugt worden sein.FIG. 5 shows a conventional key profile with basic profiles 6 on both side surfaces of the flat key. These can have been generated, for example, by milling.
Wird nun ein zweiter Werkzeugsatz 3 verwendet, dessen Werkzeugachse 2 ungleich der des ersten Werkzeugsatzes - mit dem das Grundprofil hergestellt worden ist - ist, so entsteht - wie in Figur 6 dargestellt - eine erste Hinterschneidung 1. Die Richtungsachse der Hinterschneidung 1 entspricht der Werkzeugachse 2. Es ist klar, dass eine derartige Hinterschneidung auch in mehreren der Profile erzeugt werden kann, d.h. in der Figur ist dies nur vereinfacht für ein Profil dargestellt.If a second tool set 3 is now used, the tool axis 2 of which is not the same as that of the first tool set - with which the basic profile was produced - a first undercut 1 is produced, as shown in FIG. 6. The direction axis of the undercut 1 corresponds to the tool axis 2 It is clear that such an undercut can also be created in several of the profiles, ie this is only shown in simplified form for one profile in the figure.
Gemäß der Erfindung wird nun - wie in Figur 1 gezeigt - noch eine weitere (zweite) Hinterschneidung 4 eingearbeitet. Bei dieser, von der ersten Hinterschneidung 1 ausgehenden, zweiten Hinterschneidung 4 ist die Richtungsachse nun ungleich der der ersten Hinterschneidung 1. Eine derartige Hinterschneidung 4 kann nun aber nicht mehr durch Fräsen hergestellt werden, sondern beispielsweise nur durch Räumen oder Stoßen. Auch der Einsatz eines Ziehwerkzeuges wäre möglich.According to the invention, a further (second) undercut 4 is now incorporated, as shown in FIG. 1. In this second undercut 4, starting from the first undercut 1, the directional axis is now unequal to that of the first undercut 1. However, such an undercut 4 can no longer be produced by milling, but only, for example, by broaching or butting. The use of a drawing tool would also be possible.
Eine weitere Herstellungmöglichkeit ist das gleichzeitige Erzeugen sowohl des Grundprofils als auch der ersten und zweiten Hinterschneidung in einem Arbeitsgang. Für ein derartiges Verfahren bietet sich das Pressen, Fließpressen oder auch Ziehen an.Another manufacturing option is the simultaneous creation of both the basic profile and the first and second undercut in one operation. For such a method, pressing, extrusion or even pulling lends itself.
Selbstverständlich kann hierbei noch die Richtungsachse variiert werden, wie dies in der Figur 2 dargestellt ist. Figur 3 zeigt eine einfache Hinterschneidung, die durch Räumen, Stoßen oder Ziehen in das erste Profil eingebracht wurde.Of course, the direction axis can also be varied, as shown in FIG. 2. FIG. 3 shows a simple undercut that was introduced into the first profile by broaching, pushing or pulling.
Vorstehend wurde der Begriff "Richtungsachse" verwendet. Hierunter wird die Richtung der Haupterstreckung des Profils (der Profilnut) oder der Hinterschneidung in der Richtung einer senkrecht zur Schaftlängsebene verlaufenden Ebene verstanden.The term "directional axis" was used above. This is understood to mean the direction of the main extent of the profile (the profile groove) or the undercut in the direction of a plane running perpendicular to the longitudinal plane of the shaft.
Daraus ergibt sich, dass keineswegs ein eckiger Verlauf, wie in den Figuren 1 bis 3 dargestellt, zwingend ist. Vielmehr kann sich die Richtungsachse auch ständig ändern.It follows from this that an angular course, as shown in FIGS. 1 to 3, is by no means mandatory. Rather, the directional axis can change constantly.
In der Figur 4 ist eine derartige Variante dargestellt, und zwar wurde hier eine "Freiformfläche" 5 erzeugt.Such a variant is shown in FIG. 4, namely that a "free-form surface" 5 was generated here.
Es sei noch erwähnt, dass das erfindungsgemäße Verfahren nicht nur auf Flach- sondern auch auf Rippenprofile anwendbar ist. It should also be mentioned that the method according to the invention is applicable not only to flat but also to rib profiles.
