Abstract
Description
Die Scherblätter an den vorseitig genannten Maschinen werden heute möglichst parallel geschliffen. Auch bei einer noch so präzisen Fertigung sind die Schneidkanten der Scherblätter nur begrenzt haltbar. Die Schneidkanten werden beim Gebrauch verformt und abgerundet, was zum Nachlassen der Schneidfähigkeit führt.The cutting blades on the machines mentioned above are ground as parallel as possible today. Even with the most precise production, they are Cutting edges of the shaving blades have a limited shelf life. The cutting edges are deformed and in use rounded off, leading to a decrease in cutting ability leads.
Um einen gebrauchsfähigen Zustand wieder herzustellen, müssen die Werkzeuge auseinandergebaut und nachgear beitet werden.To restore a usable condition, the tools must be disassembled and reworked be prepared.
Diesem Nachteil wollen wir mit unserer Erfindung da
durch begegnen, daß wir durch ein elektrolytisches
Verfahren eine Dispersionsschicht aufbauen, die ein
kontinuierliches, selbsttätiges Nachschärfen der
Scherblätter bewirkt.
We want to counter this disadvantage with our invention by using an electrolytic process to build up a dispersion layer, which brings about a continuous, automatic re-sharpening of the shear blades.

Galvanisch erzeugte Dispersionsschichten werden nach ¹) bisher für andere Zwecke verwendet:Electroplated dispersion layers are after ¹) previously used for other purposes:
- - Überzüge zur Erhöhung der Verschleiß- und Abrieb festigkeit- Coatings to increase wear and abrasion strength
- - Dispersionsgehärtete Überzüge- Dispersion hardened coatings
- - poröse Schichten- porous layers
- - Überzüge zur Verbesserung des Korrosionsschutzes.- Coatings to improve corrosion protection.
Nach OS 22 30 676 vom 23.6.1972 wird z.B. eine abnutzungs feste Schicht erzeugt, die dadurch gekennzeichnet ist, daß in eine Metallmatrix Diamantpartikelchen eingebettet sind.According to OS 22 30 676 from June 23, 1972, e.g. a wear and tear solid layer, which is characterized by that embedded in a metal matrix diamond particles are.
Dispersionsüberzüge mit eingebauten Schleifstoffen werden u.a. für folgende Artikel angewandt:Dispersion coatings with built-in abrasives are among others applied to the following articles:
- - Diamantbeschichtete Feilen (z.B. für den Werkzeugbau)- Diamond coated files (e.g. for tool making)
- - Nagelfeilen- Nail filing
- - Zahntechnische Instrumente- Dental instruments
- - Polier-, Schleif- und Schneidwerkzeuge.- Polishing, grinding and cutting tools.
All diese Dispersionsüberzüge sind nicht dafür vorge
vorgesehen, ein selbsttätiges Nachschärfen von Scher
blättern zu bewirken.
All of these dispersion coatings are not intended to effect an automatic re-sharpening of shear blades.
Die Erfindung betrifft ein galvanisches Verfahren zur Herstellung einer Dispersionsschicht mit selbsttätiger, nachschärfender Wirkung an Schneidkanten von Scherblät tern jeglicher Art.The invention relates to a galvanic method for Production of a dispersion layer with automatic, resharpening effect on cutting edges of shear blade of any kind.
Durch die Relativbewegung der Scherblätter gegeneinan der werden in der aufgetragenen Dispersionsschicht Schleifpartikel freigelegt, die ein Nachschleifen der Schneidkanten bewirken.Due to the relative movement of the blades against each other which are in the applied dispersion layer Exposed abrasive particles that regrind the Effect cutting edges.
Das setzt voraus, daß eine hohe Dichte an Schleifpar tikeln in der Matrix enthalten ist, daß eine gute Haftung der Metallmatrix auf dem Grundmaterial gewähr leistet ist und daß die Dispersionsschicht eine gute Duktilität und Widerstandsfähigkeit gegen punktuelle Erhitzungen besitzt.This presupposes that a high density of grinding par Articles contained in the matrix is that good Ensure liability of the metal matrix on the base material is and that the dispersion layer is a good one Ductility and resistance to punctual Has heating.
Bei dem Vorgang des stetigen Nachschärfens der Schneid kanten erfolgt ein geringer Materialabtrag wobei aber gleichzeitig immer neue Schleifpartikel in der Metall matrix freigelegt werden und so ein fortlaufender Prozeß bis zur völligen Abnutzung der Scherblätter stattfindet.In the process of constantly resharpening the cutting edges, there is a small amount of material removed At the same time, there are always new grinding particles in the metal matrix are exposed and thus a continuous Process up to complete wear of the shaving blades takes place.
Es ist darauf zu achten, daß die mittlere Partikel größe dem Anwendungszweck und der Größe der Maschine entspricht. Die Größe der Partikel sollte jedoch 100 µm nicht übersteigen.Care should be taken that the middle particle size of the application and the size of the machine corresponds. The size of the particles should, however Do not exceed 100 µm.
Bei Haarschermaschinen haben sich mittlere Partikel größen von bis zu 3 µm bewährt.There are medium particles in hair clippers proven sizes of up to 3 µm.
Der Anteil der in der Dispersionsschicht enthaltenen Partikel sollte von bis zu 60 Vol.%, vorzugsweise von bis zu 40 Vol.% betragen.The proportion of those contained in the dispersion layer Particles should be up to 60 vol%, preferably from up to 40 vol.%.
Bei den einzubettenden Partikeln kann es sich handeln um:The particles to be embedded can be around:
- - atomare Feststoffe wie z.B. Diamanten, Glaskohlen stoff und Wolfram - atomic solids such as Diamonds, glass coals fabric and tungsten
- - molekulare Feststoffe wie z.B. Aluminiumoxyd, Silizium karbid, Borkarbid, PTFE, PVDE und Trippel- molecular solids such as Aluminum oxide, silicon carbide, boron carbide, PTFE, PVDE and triple
- - zähviskose Flüssigkeiten wie z.B. Glas, hochmolekulare Polyglykole- viscous liquids such as Glass, high molecular weight Polyglycols
- - durch gezielte Züchtung von Kristallstrukturen oder Aglomeration- through targeted growth of crystal structures or Aglomeration
Die Partikel können elektrisch leitend oder elektrische Isolatoren sein. Entsprechend bilden sich unterschied liche Dispersionsschichten aus, die sich dadurch unter scheiden, daß sich an den elektrisch leitenden Partikeln auch Metallatome der Matrix anlagern (siehe ¹).The particles can be electrically conductive or electrical Insulators. Differences are formed accordingly Liche dispersion layers, which are thereby divorce that on the electrically conductive particles also attach metal atoms to the matrix (see ¹).
