AUSGEGEBEN AM 6. JUNI 1957ISSUED JUNE 6, 1957
Die Erfindung betrifft ein Verfahren zum Verbinden eines Tragkörpers mit einer flachen, mit Öffnungen versehenen, metallischen Schneidplatte eines Trockenrasiergerätes, die nach -dem Verbinden mit dem Tragkörper radial gespannt ist.The invention relates to a method for connecting a support body with a flat, with Openings provided, metallic cutting plate of a dry shaver, which after connecting is tensioned radially with the support body.
Die Erfindung bezweckt, eine völlig flach gespannte Schneidplatte zu erzielen und benutzt hierfür Werkstoffe verschiedener Wärmeausdehnungskoeffizienten für Schneidplatte und Tragkörper.The aim of the invention is to achieve a completely flat cutting insert and uses it for this purpose Materials with different coefficients of thermal expansion for cutting insert and tool body.
Es ist bekannt, metallische Platten an einem Tragkörper durch Anwendung von Wärme, z. B. durch Sahweißen, zu befestigen. Da hierbei die Erwärmung nuir örtlich angewandt wird·, entsteht die Gefahr, daß nach dem Befestigen die Platten keine ebenen Flächen bilden, sondern Falten und Beulen aufweisen. Deshalb war man bestrebt, nach der Befestigung durch Anwendung von Preßdruck und Erhitzung eine glattgespannte Platte zu erhalten.It is known to attach metallic plates to a support body by applying heat, e.g. B. by saw-white to fasten. Since the heating is only applied locally here, the There is a risk that, after fastening, the panels will not form flat surfaces, but folds and dents exhibit. Therefore, one endeavored after the attachment by applying pressure and Heating to obtain a smoothly stretched plate.
Es ist auch bekannt, derartige Falten und Beulen durch Hämmern nach der Befestigung zu entfernen. It is also known to remove such wrinkles and dents by hammering after fastening.
Weiter ist es bekannt, daß beim Erwärmen einer auf einem Tragkörper befestigten Platte infolge der verschiedenen Abkühlgesahwiindigkedten Beulen in der Platte entstehen. Durch Anwendung von Preßdiruck wird diesen Beulen eine bestimmte Gestalt gegeben.It is also known that when a plate attached to a support body is heated, as a result of the various bumps tied to the coolant arise in the plate. By applying pressure pressure, these bumps are given a certain shape given.
Diese bekannten Verfahren weisen den Nachteil auf, daß nach der Verbindung noch eine zuisätzliche Behandlung notwendig ist. Überdies eignen sich die bekannten Verfahren schlecht für die Schneidplatte eines Trockenrasiergerätes, weil dieseThese known methods have the disadvantage that, after the connection, an additional one Treatment is necessary. In addition, the known methods are poorly suited for the Cutting plate of a dry shaver because this

Schneidplatten klein und sehr dünn sind. Für die Zusammenarbeit mit dem Schneidoirgan aber muß die Schneidplatte vollkommen flach und so stark wie möglich gespannt sein.Inserts are small and very thin. For the In cooperation with the cutting organ, however, the cutting plate must be completely flat and so strong be excited as possible.
Nadh der Erfindung werden Schneidplatte und Tragkörper gemeinsam erwärmt, dann durch Kleben mittels eines thermisch aush'ärtbaren oder thermoplastischen, die erforderliche Bindekraft auch, bei mehr als Zimmertemperatur aufweisenden ίο Stoffes miteinander verbunden und darauf abgekühlt, wobei der Ausdehnungskoeffizient des Schneidplattenwerkstoffes größer ist als der des Tragkörperwerkstoffes.According to the invention, the cutting insert and the support body are heated together, then through Gluing by means of a thermally curable or thermoplastic, the required binding force Also, if the ίο substance is more than room temperature, it is connected to one another and then cooled down, wherein the coefficient of expansion of the insert material is greater than that of the Support body material.
Vorzugsweise wird die Schneidplatte unter Zwischenfügung des Klebstoffes ■ vor dem Erwärmen auf den Tragkörper gelegt, wobei es von Vorteil ist, wenn der Tragkörper aus Metall besteht. Preferably, the cutting plate is inserted with the adhesive ■ prior to heating placed on the support body, it being advantageous if the support body is made of metal.
Bei Verwendung einer Schneidplatte aus Stahl wählt man vorzugsweise den Tragkörper aus einer Niekel-Eisen-Legierung mit kleinem Ausdehnungskoeffizienten. When using a cutting plate made of steel, one preferably selects the support body from one Niekel iron alloy with a small expansion coefficient.
Durch die verschieden gewählten Ausdehnungskoeffizienten von Platte und Tragkörper und durch die Anwendung eines Verbindungsmittels, das auch bei mehr als Zimmertemperatur die erforderliche Bindekraft aufweist, ist die Möglichkeit gegeben, die Platte in erhitztem Zustand am Tragkörper zu befestigen. Darauf kann das Ganze abgekühlt werden, wobei noch vor dem Erreichen der Zimmertemperatur sich Platte und Tragkörper miteinander verbinden. Während der weiteren Abkühlung tritt selbsttätig die erforderliöhe Spannung in der Platte auf, ohne daß zu diesem Zweck besondere Mittel angewendet werden müssen.Due to the different expansion coefficients of the plate and support body and through the use of a lanyard that is also required at more than room temperature Has binding force, there is the possibility of the plate in the heated state on the support body attach. Then the whole thing can be cooled down, but before reaching room temperature plate and support body connect to one another. During further cooling occurs automatically the required tension in the plate, without any special means for this purpose must be applied.
Auf diese Weise ergibt sich ein einwandfreier und billiger Gegenstand, bei dem die Schneidplatte völlig flach gespannt ist.This results in a flawless and inexpensive object in which the cutting insert is stretched completely flat.
Eine nach der Erfindung mit einem Tragkörper verbundene Schneidplatte hat für die beabsichtigte Verwendung einen hinreichenden Widerstand gegen Farmveränderung. Sie ist bekanntlich mit 'Öffnungen zur Einführung der Haare versehen, und hinter ihr kann ein Schneidorgan zum Abschneiden dieser Haare betätigt werden. Die Dicke der Schneidplatte bedingt hier den Abstand desjenigen Punktes von der Haut, an welchem die Haare abgeschnitten werden. Da zur einwandfreien Wirkung eines Trockenrasiergerätes dieser Abstand möglichst klein sein muß, ist es wesentlich, die Schneidplatte so dünn wie möglich zu bemessen. Das Zusammenwirken zwischen Schneidplatte und Sohneidorgan verlangt aber, daß die erste ihre Form möglichst wenig ändert, wenn sie an die zu rasierende Haut angedrückt wird. Jede Formveränderung der Sohneidplatte hat ja ein weniger gutes Anliegen des Schneidorgans an der Schneidplatte zur Folge, wodurch die Schneidwirkung beeinträchtigt wird. In gewissen Fällen ist es sogar möglich, daß die Haare nicht abgeschnitten, sondern zwischen der Schneidplatte und dem Schneidorgan festgeklemmt werden, so daß die zu rasierende Person ein schmerzhaftes - Ziehen art den Haaren empfindet.A cutting insert connected to a support body according to the invention has for the intended Use adequate resistance to farm change. It is known to be with 'openings provided for the introduction of the hair, and behind it can be a cutting element for cutting off these hairs are pressed. The thickness of the cutting plate determines the distance between the one here Point of the skin at which the hair was cut will. Since this distance must be as small as possible for a dry shaver to work properly, it is essential that the Make the insert as thin as possible. The interaction between the insert and But the son's oath requires that the first change its form as little as possible when it adjoins the shaving skin is pressed against it. Every change in shape of the son's oath has one less result in good contact between the cutting element and the cutting plate, which impairs the cutting effect will. In certain cases it is even possible that the hair is not cut off, but rather be clamped between the cutting plate and the cutting member, so that the to be shaved Person feels a painful - pulling kind of hair.
