Abstract
Description
Die Erfindung betrifft einen Nagelschlagbacken für Maschinen zur Nagelherstellung, bestehend aus einem länglichen, prismenförmigen Grundkörper mit trapezförmigem Querschnitt, der an einem Ende eine oder mehrere symmetrisch zum Querschnitt angeordnete Spannrillen aufweist, die jeweils in eine halbkegelförmige Ausnehmung übergehen, wobei die Spannrillen in einem in einer Ausnehmung des Grundkörpers angeordneten Einsatz eingearbeitet sind.The invention relates to a nail beating jaw for machines for nail production, consisting of an elongated, prismatic base body with a trapezoidal cross section, which has at one end one or more clamping grooves arranged symmetrically to the cross section, each of which merges into a semi-conical recess, the clamping grooves being in one in one Recess of the base body arranged insert are incorporated.
Derartige Nagelschlagbacken werden in Maschinen, wo Draht zu Nägeln umgeformt wird, paarweise eingesetzt. Sie sind so angeordnet, daß sich die Spannrillen gegenüberliegen. Im Zuge des Arbeitsablaufes werden die Nagelschlagbacken geschlossen oder geöffnet. Im geschlossenen Zustand wird der eingeführte Draht durch die Spannrillen geklemmt. Die an die Spannrille anschließende halbkegelförmige Ausnehmung dient der besseren Zuführung des Drahtes. Im geklemmten Zustand wird dann der Nagelkopf angestaucht und anschließend der Nagel abgeschnitten. Zur besseren Klemmung des Drahtes wird die Spannrille zum Beispiel mit halbkreisförmig verlaufenden Querrillen profiliert.Such nail flap jaws are used in pairs in machines where wire is formed into nails. They are arranged so that the clamping grooves are opposite one another. In the course of the workflow, the nailing jaws are closed or opened. In the closed state, the inserted wire is clamped through the tension grooves. The semi-conical recess adjoining the clamping groove serves for better feeding of the wire. In the clamped state, the nail head is then pressed up and the nail is then cut off. For better clamping of the wire, the clamping groove is profiled, for example, with semicircular transverse grooves.
Man unterscheidet zwischen einadrigen oder zweiadrigen Nagelschlagbacken, wo entweder eine oder zwei nebeneinanderliegende Spannrillen eingearbeitet sind. Die zweiadrige Ausführung ermöglicht die gleichzeitige Fertigung von zwei Nägeln, also eine Verdoppelung der Produktionsleistung.A distinction is made between single-core or two-core nailing jaws, where either one or two adjacent grooves are incorporated. The two-wire design enables the simultaneous production of two nails, i.e. a doubling of the production output.
Derartige Nagelschlagbacken werden großteils aus Stahl gefertigt. Sie haben aufgrund der nicht optimalen Verschleißfestigkeit von Stahl aber nur eine begrenzte Standzeit. Ist der Verschleiß der Spannrillen unzulässig hoch, müssen die Nagelschlagbacken ausgewechselt werden.Such nail blow jaws are largely made of steel. However, due to the non-optimal wear resistance of steel, they only have a limited service life. If the wear on the clamping grooves is impermissibly high, the nailing jaws must be replaced.
Um die Verschleißfestigkeit der Nagelschlagbacken zu erhöhen, ist man dazu übergegangen, den Bereich des Werkzeuges, in den die Spannrille eingearbeitet ist, aus verschleißfesterem Material, z. B. Hartmetall, herzustellen. Dazu wird der verschleißfeste Einsatz in eine entsprechende Ausnehmung des Werkzeuges eingelötet. Die Kosten eines derartigen Werkzeuges sind aufgrund eines recht aufwendigen Herstellungsverfahrens im Vergleich zu einem völlig aus Stahl bestehenden Nagelschlagbacken um einiges höher. Die Standzeit eines derartigen mit Hartmetall bestückten Nagelschlagbackens ist bestenfalls etwa fünfmal so hoch, wie diejenige eines Stahl Nagelschlagbackens. Vielfach kann es aber auch zu einem vorzeitigen Ausfall eines Hartmetall bestückten Nagelschlagbackens durch Risse aufgrund der Lötspannungen in der Lötverbindung kommen. Selbst wenn nur ein Nagelschlagbacken vorzeitig ausfällt, werden in der Praxis beide Nagelschlagbacken ausgewechselt, da die Nagelschlagbacken immer paarweise gefertigt werden und bei Austausch eines einzelnen Nagelschlagbackens die immer höheren Anforderungen an die Genauigkeit der Nägel nicht gehalten werden können.
Aufgrund dieses oftmals recht ungünstigen Preis/Leistungs-Verhältnisses haben sich solche mit Hartmetall bestückten Nagelschlagbacken nicht in größerem Umfang durchgesetzt.In order to increase the wear resistance of the nailing jaws, it has gone over to the area of the tool into which the clamping groove is made of more wear-resistant material, e.g. B. hard metal. For this purpose, the wear-resistant insert is soldered into a corresponding recess in the tool. The cost of such a tool is due to a very complex manufacturing process compared to a nail hammer made entirely of steel much higher. The service life of such a nail hammer jaw equipped with hard metal is at best about five times as long as that of a steel nail hammer jaw. In many cases, however, there may be a premature failure of a hard metal-tipped nail hammer jaw due to cracks due to the soldering stress in the soldered connection. Even if only one nailing jaw fails prematurely, in practice both nailing jaws are exchanged, since the nailing jaws are always manufactured in pairs and when replacing a single nailing jaw the ever increasing demands on the accuracy of the nails cannot be met.
Due to this often quite unfavorable price / performance ratio, such hard-tipped nail hammer jaws have not become widely accepted.
Die DD-PS 40 525 beschreibt einen Nagelschlagbacken aus einem länglichen, prismenförmigen Grundkörper mit trapezförmigem Querschnitt mit einer Ausnehmung an einem Ende, in die ein sechskantförmiger Einsatz umsetzbar und auswechselbar eingesetzt ist. In die Mantelflächen des sechskantförmigen Einsatzes sind die Spannrillen eingearbeitet. Der Einsatz ist lediglich durch ein mit Schrauben befestigtes Blech im Grundkörper fixiert. Dadurch ist die Befestigung des Einsatzes im Grundkörper nur unzureichend und es kommt insbesondere bei beweglichen Nagelschlagbacken, die mit einer Frequenz von etwa 1000 Hüben/min arbeiten beim kleinsten Spiel in der Aufnahme zur frühzeitigen Zerstörung der Auflage für den Einsatz.DD-PS 40 525 describes a nail beating jaw made of an elongated, prism-shaped base body with a trapezoidal cross-section with a recess at one end into which a hexagonal insert can be implemented and replaced. The clamping grooves are incorporated into the lateral surfaces of the hexagonal insert. The insert is only fixed in the base body by a plate fastened with screws. As a result, the attachment of the insert in the base body is inadequate and it comes in particular with movable nailing jaws that work at a frequency of about 1000 strokes / min in the smallest game in the recording for the early destruction of the support for use.
Der Erfindung liegt die Aufgabe zugrunde, einen Nagelschlagbacken für Maschinen zur Nagelherstellung zu schaffen, der einen umsetzbaren und auswechselbaren Schneideinsatz aufweist und bei dem gegenüber bekannten Ausführungen eine wesentlich verbesserte Klemmung des Einsatzes im Grundkörper gewährleistet ist.The invention has for its object to provide a nail hammer for machines for nail production, which has a convertible and replaceable cutting insert and in which a significantly improved clamping of the insert in the base body is ensured compared to known designs.
Erfindungsgemäß wird dies dadurch erreicht, daß der Grundkörper in Längsrichtung zur Klemmung des Einsatzes einen die Ausnehmung für den Einsatz jedoch nicht die halbkegelförmige Ausnehmung durchsetzenden Schlitz aufweist, so daß zwei federnde Abschnitte gebildet sind, die durch eine Klemmschraube gegeneinander verspannbar sind.According to the invention this is achieved in that the base body in the longitudinal direction for clamping the insert has a slot penetrating the recess for the insert but not the semi-conical recess, so that two resilient sections are formed which can be clamped against one another by a clamping screw.
Auf diese Art und Weise wird erreicht, daß der Einsatz ohne Spiel im Grundkörper festklemmbar ist und trotzdem ein rasches Umsetzen und Auswechseln des Einsatzes gewährleistet ist. Durch die spezielle Klemmung wird darüberhinaus ein störungsfreier Drahteinlauf und damit eine kontinuierliche Fertigung gewährleistet.In this way it is achieved that the insert can be clamped in the base body without play and nevertheless a quick transfer and replacement of the insert is ensured. The special clamping also ensures trouble-free wire entry and thus continuous production.
In einer besonders vorteilhaften Ausgestaltung der Erfindung ist der Einsatz aus Hartmetall gefertigt und würfel- oder quaderförmig mit je einer senkrecht verlaufenden Spannrille in jeder Mantelfläche ausgeführt. Auf diese Art und Weise wird eine vierfache Verwendung des Hartmetalleinsatzes bei kostengünstiger Fertigung und guter Klemmung ermöglicht.In a particularly advantageous embodiment of the invention, the insert is made of hard metal and is cube-shaped or cuboid with a vertically running tensioning groove in each lateral surface. In this way, a fourfold use of the hard metal insert is made possible with inexpensive production and good clamping.
In einer anderen vorteilhaften Ausgestaltung ist der Einsatz würfelförmig mit jeweils einer senkrecht verlaufenden Spannrille in zwei aneinandergrenzenden Mantelflächen und mit einer horizontal verlaufenden Spannrille in einer weiteren Mantelfläche ausgeführt. Auf diese Art und Weise wird die Kerbwirkung herabgesetzt und ein derartiger Einsatz ist insbesondere für starke Belastung bei der Nagelproduktion geeignet.In another advantageous embodiment, the insert is cube-shaped, each with a vertically running clamping groove in two adjoining lateral surfaces and with a horizontally running clamping groove in a further lateral surface. This way and In this way, the notch effect is reduced and such an insert is particularly suitable for heavy loads in nail production.
In einer weiteren besonderen Ausführung der Erfindung verläuft der Klemmschlitz parallel zu einer Seitenfläche des Grundkörpers. Auf diese Weise wird erreicht, daß der Schlitz außerhalb der halbkegelförmigen Drahtzuführung verläuft und trotzdem noch eine gute Klemmung des Hartmetalleinsatzes gewährleistet wird. Im folgenden wird die Erfindung anhand von Figuren näher erläutert.In a further special embodiment of the invention, the clamping slot runs parallel to a side surface of the base body. In this way it is achieved that the slot runs outside the semi-conical wire feed and still ensures good clamping of the hard metal insert. The invention is explained in more detail below with reference to figures.

Figur 1 zeigt einen erfindungsgemäßen Nagelschlagbacken, bestehend aus einem länglichen, prismenförmigen Grundkörper -1- aus Stahl. Die Seitenflächen des Grundhalters sind jeweils zueinander um 15° geneigt, so daß der Grundkörper einen trapezförmigen Querschnitt aufweist. An seinem vorderen Ende weist der Grundkörper -1- eine Ausnehmung zur Aufnahme eines würfelförmigen Einsatzes -2- aus Hartmetall auf. Die Ausnehmung ist so ausgeführt, daß der Einsatz -2- an der Stirnseite und Deckfläche des Grundkörpers -1- geringfügig übersteht. An der Stirnseite des Einsatzes -2- ist die mittig angeordnete, senkrechte Spannrille -5- mit halbkreisförmigem Querschnitt zur Klemmung des Drahtes zu sehen. Unterhalb des Einsatzes -2- ist im Grundkörper -1- stirnseitig eine sich nach unten erweiternde halbkegelförmige Ausnehmung -6- zur Drahtzuführung eingearbeitet, die in die Spannrille -5- des Einsatzes -2- mündet. Zur Klemmung des Einsatzes -2- weist der Grundkörper -1- in Längsrichtung einen stirnseitig beginnenden, die Ausnehmung für den Einsatz -2- durchsetzenden Schlitz -3- auf, so daß zwei federnde Abschnitte des Grundkörpers -1- gebildet werden, die durch eine Klemmschraube -4- gegen den Einsatz -2- verspannbar sind. Der Schlitz -3- verläuft außermittig parallel zu einer Seitenfläche des Grundkörpers -1-, so daß er die halbkegelförmige Ausnehmung -6- für den Drahteinlauf nicht durchsetzt. Auf diese Weise wird eine problemlose Drahtzuführung gewährleistet. Die Klemmschraube -4- ist senkrecht zum Schlitz -3- angeordnet.FIG. 1 shows a nailing jaw according to the invention, consisting of an elongated, prism-shaped base body -1- made of steel. The side faces of the base holder are inclined at 15 ° to one another, so that the base body has a trapezoidal cross section. At its front end, the base body -1- has a recess for receiving a cube-shaped insert -2- made of hard metal. The recess is designed so that the insert -2- protrudes slightly on the front and top surface of the base body -1-. On the front side of the insert -2- you can see the central, vertical clamping groove -5- with a semicircular cross-section for clamping the wire. Below the insert -2- in the base body -1- a downwardly widening semi-conical recess -6- for the wire feed is worked in, which opens into the clamping groove -5- of the insert -2-. To clamp the insert -2-, the base body -1- has a lengthwise beginning, the recess for the insert -2- penetrating slot -3-, so that two resilient sections of the base body -1- are formed, which can be clamped against the insert -2- by a clamping screw -4-. The slot -3- runs eccentrically parallel to a side surface of the base body -1- so that it does not pass through the semi-conical recess -6- for the wire inlet. This ensures problem-free wire feeding. The clamping screw -4- is arranged perpendicular to the slot -3-.
Figur 2 zeigt den Hartmetalleinsatz für den Nagelschlagbacken nach Figur 1 in vergrößerter Darstellung. In jede Mantelfläche ist mittig je eine senkrecht verlaufende Spannrille -5- mit halbkreisförmigem Querschnitt eingearbeitet. Zur besseren Klemmung des Drahtes sind die Spannrillen mit einer Querprofilierung versehen. Auf diese Weise ist eine vierfache Verwendung des Einsatzes -2- ermöglicht.FIG. 2 shows the hard metal insert for the nail beating jaw according to FIG. 1 in an enlarged view. A vertical clamping groove -5- with a semicircular cross-section is worked into the middle of each lateral surface. For better clamping of the wire, the clamping grooves are provided with a cross profile. In this way, the insert -2- can be used four times.
Figur 3 zeigt eine weitere Variante eines Schneideinsatzes -2- für den Nagelschlagbacken nach Figur 1. Bei dieser Variante weist der Einsatz an zwei aneinandergrenzenden Mantelflächen jeweils eine mittig angeordnete, senkrecht verlaufende Spannrille -5- auf, während eine weitere Mantelfläche mit einer mittig angeordneten, horizontal verlaufenden Spannrille -5- versehen ist. Unter Umständen kann auch noch die vierte Mantelfläche mit einer horizontal verlaufenden Spannrille -5- versehen werden. Durch die Ausführung eines Einsatzes -2- nach Figur 3 wird die bei der Bearbeitung auftretende Kerbwirkung herabgesetzt, so daß eine derartige Ausführung, insbesondere bei starker Belastung, vorteilhaft ist.FIG. 3 shows a further variant of a cutting insert -2- for the nail beating jaw according to FIG. 1. In this variant, the insert on two adjacent lateral surfaces each has a centrally arranged, vertically extending clamping groove -5-, while a further lateral surface with a centrally arranged, horizontal clamping groove -5- is provided. Under certain circumstances, the fourth lateral surface can also be provided with a horizontally running clamping groove -5-. By executing an insert -2- according to FIG. 3, the notch effect that occurs during machining is reduced, so that such an embodiment is advantageous, particularly under heavy loads.
Die Zeichnungen betreffen besonders vorteilhafte Ausgestaltungen der Erfindung. Die Erfindung ist jedoch keinesfalls auf diese Ausführungen beschränkt. So ist insbesondere die Form des Einsatzes -2- keinesfalls auf würfelförmige Ausführungen beschränkt. Prismen mit dreieckförmiger Grundfläche und abgestumpften Ecken oder mit mehreckiger, z. B. sechseckförmiger Grundfläche sind als Einsatz -2- ebenfalls geeignet.The drawings relate to particularly advantageous embodiments of the invention. However, the invention is in no way limited to these statements. In particular, the shape of the insert -2- is in no way limited to cube-shaped designs. Prisms with a triangular base and blunted corners or with polygonal, z. B. hexagonal base are also suitable as insert -2-.
