Abstract
Description
Die Erfindung betrifft einen verschleißfesten Werkzeugeinsatz für Maschinen zur Herstellung von Nägeln, Schrauben, Nieten und dergleichen aus drahtförmigem Ausgangsmaterial.The invention relates to a wear-resistant tool insert for machines for the production of nails, screws, rivets and the like wire-shaped starting material.
Derartige Werkzeugeinsätze sind sogenannte Schlag- bzw. Klemmbacken sowie Zwickbacken, die in der Maschine jeweils paarweise eingesetzt werden. Die Klemmbacken werden vielfach als umsetzbare und auswechselbare Einsätze in Werkzeughaltern in der Regel in Form von länglichen, prismenförmigen Grundkörpern mit trapezförmigem Querschnitt in entsprechenden Ausnehmungen dieses Werkzeughalters eingesetzt und festgeklemmt. Die Klemmbacken weisen auf einer Einsatzfläche eine oder mehrere Spannrillen zum Festklemmen des zugeführten Drahtes sowie eine Ausnehmung zur Anformung der gewünschten Kopfform des herzustellenden Teiles auf. Sie sind in der Maschine so angeordnet, daß sich die Spannrillen der paarweise eingesetzten Einsätze gegenüberliegen. Im Zuge des Arbeitsablaufes werden die Klemmbacken geschlossen oder geöffnet. Im geschlossenen Zustand wird der eingeführte Draht durch die Spannrillen festgeklemmt. Im festgeklemmten Zustand wird dann der Kopf der Nägel, Schrauben oder Nieten angestaucht. Zur besseren Klemmung des Drahtes sind die Spannrillen vorzugsweise mit halbkreisförmig verlaufenden Querrillen profiliert. Nach Fertigstellen des Kopfes wird das Teil durch Schließen von zwei gegenüberliegenden Zwickbacken abgelängt. Die Zwickbacken werden ebenfalls in Werkzeughaltern oder direkt in der Maschine festgeklemmt. Sie weisen ein symmetrisches Profil mit mehreren Schneiden auf, durch das einerseits das Ende des fertigen Teiles angeformt und der Teil abgelängt und andererseits gleichzeitig die Ausgangsgeometrie zur Ausbildung des Kopfes des nächsten Teiles angeformt wird.Such tool inserts are so-called striking or clamping jaws as well as lasting jaws, which are used in pairs in the machine. The jaws are often implemented and exchangeable Inserts in tool holders usually in the form of elongated, prismatic bodies with trapezoidal cross section in corresponding recesses of this tool holder used and clamped. The clamping jaws have one or several clamping grooves for clamping the supplied wire and one Recess to form the desired head shape of the one to be produced Part on. They are arranged in the machine so that the clamping grooves of the inserts used in pairs. In the course of Workflow, the jaws are closed or opened. in the the inserted wire is closed by the tension grooves clamped. In the clamped state, the head of the nails Bolts or rivets upset. For better clamping of the wire the clamping grooves are preferably with semicircular transverse grooves profiled. After finishing the head, the part is closed by closing two opposite jaws cut to length. The pinch cheeks are also clamped in tool holders or directly in the machine. she have a symmetrical profile with several cutting edges, through which on the one hand the end of the finished part is molded and the part is cut to length and on the other hand, the initial geometry for the formation of the head of the next part is molded.
Bei den Klemmbacken unterscheidet man zwischen einadrigen oder zweiadrigen Klemmbacken, wo entweder eine oder zwei nebeneinanderliegende Spannrillen eingearbeitet sind. A distinction is made between single-core or two-core jaws, where either one or two adjacent grooves are incorporated.
Die zweiadrige Ausführung ermöglicht die gleichzeitige Fertigung von zwei Nägeln, Schrauben oder Nieten, also eine Verdoppelung der Produktionsleistung. Die Zwickbacken werden in der Regel immer nur einadrig ausgeführt, so daß in Verbindung mit zweiadrigen Klemmbacken vier Zwickbacken zur Anwendung kommen.The two-wire version enables the simultaneous production of two Nails, screws or rivets, i.e. a doubling of the Production output. The lasting jaws are usually only single-core executed so that four in connection with two-core jaws Pinches are used.
Die Werkzeugeinsätze werden zur Verringerung des Verschleisses vielfach aus Hartmetall hergestellt. Ist der Verschleiß der Spannrillen bzw. der Schneiden unzulässig hoch, müssen die Einsätze ausgewechselt werden.The tool inserts are widely used to reduce wear Carbide made. Is the wear of the clamping grooves or the cutting edges the stakes must be replaced.
Hartmetall und andere harte, verschleißfeste Werkstoffe weisen zwar neben
einer hohen Druckfestigkeit eine sehr hohe Härte und damit hohe
Verschleißfestigkeit auf, sind aber hinsichtlich Zug- und
Biegebeanspruchungen nur mäßig belastbar.
Aufgrund von Unregelmäßigkeiten in der Drahtqualität hinsichtlich
schwankender Abmessungen oder unterschiedlicher Festigkeiten kann es bei
der Herstellung der Nägel, Schrauben oder Nieten zu sehr hohen
Zugbeanspruchungen und damit Überbeanspruchungen der Einsätze aus
verschleißfestem Material kommen, was vielfach mit einem Bruch der Einsätze
verbunden ist.In addition to high compressive strength, hard metal and other hard, wear-resistant materials have very high hardness and thus high wear resistance, but are only moderately resilient with regard to tensile and bending stresses.
Due to irregularities in the wire quality with regard to fluctuating dimensions or different strengths, the manufacture of the nails, screws or rivets can lead to very high tensile loads and thus excessive stresses on the inserts made of wear-resistant material, which is often associated with a breakage of the inserts.
Der Erfindung liegt die Aufgabe zugrunde, verschleißfeste Werkzeugeinsätze für Maschinen zur Herstellung von Nägeln, Schrauben, Nieten und dgl. zu schaffen, bei denen gegenüber bekannten Ausführungen eine unzulässige Überbeanspruchung durch zu hohe Zugspannungen und damit ein frühzeitiges Brechen vermieden wird.The invention has for its object wear-resistant tool inserts for machines for the production of nails, screws, rivets and the like create an inadmissible compared to known designs Overstraining due to excessive tensile stresses and therefore premature Breaking is avoided.
Erfindungsgemäß wird dies dadurch erreicht, daß der Werkzeugeinsatz in Axialrichtung des zugeführten Drahtes geteilt ausgeführt ist. According to the invention this is achieved in that the tool insert in Axial direction of the supplied wire is divided.
Auf diese Art und Weise wird erreicht, daß der Einsatz aus verschleißfestem Material bei Überbelastung kontrolliert "nachgeben" kann, wodurch unzulässig hohe Zugspannungen, die zu einem Bruch des Einsatzes führen könnten, vermieden werden.In this way it is achieved that the use of wear-resistant Material can "yield" in a controlled manner when overloaded, which makes it impermissible high tensile stresses that could break the insert, be avoided.
In einer vorteilhaften Variante der Erfindung sind die einzelnen Teile durch eine Niet- oder Schraubverbindung miteinander verbunden.In an advantageous variant of the invention, the individual parts are by a Rivet or screw connection connected.
In einer anderen Variante werden die einzelnen Teile des Werkzeugeinsatzes über den Werkzeughalter bzw. über den Maschinenteil, in den sie eingesetzt werden, zusammengepreßt.In another variant, the individual parts of the tool insert via the tool holder or the machine part in which it is inserted are pressed together.
In einer anderen vorteilhaften Ausgestaltung stehen die einzelnen Teile über eine zumindest teilweise gezahnte Oberfläche miteinander in Verbindung. Diese Ausgestaltung ist insbesondere dann von Vorteil, wenn keine Verbindungselemente, wie Schrauben oder Nieten, zum Verbinden der einzelnen Teile vorgesehen sind. Durch das Sägezahnprofil werden Kräfte in Richtung des Anpreßdruckes an den Draht aufgenommen und ein besonders guter Formschluß der einzelnen Teile miteinander erreicht.In another advantageous embodiment, the individual parts protrude an at least partially serrated surface in connection. This configuration is particularly advantageous if none Connecting elements, such as screws or rivets, for connecting the individual parts are provided. The sawtooth profile forces in Direction of the pressure applied to the wire and a special one good interlocking of the individual parts achieved.
Als besonders vorteilhaftes Material für den Werkzeugeinsatz wird Hartmetall verwendet.Carbide is a particularly advantageous material for tool use used.
