Description
Die Erfindung betrifft einen verschleißfesten in Maschinen einsetzbaren, Werkzeughalbeinsatz zur Formgebung und zum Ablängen von Nägeln, Schrauben und Nieten aus drahtförmigem Ausgangsmaterial.The invention relates to a wear-resistant tool insert that can be used in machines for shaping and cutting to length nails, screws and rivets wire-shaped starting material.
Derartige Werkzeughalbeinsätze sind sogenannte Schlag- bzw. Klemmbacken sowie Zwickbacken, die in der Maschine in identischer Ausgestaltung jeweils paarweise eingesetzt werden. Die Klemmbacken werden entsprechend der EP-A-0 401 918 vielfach als umsetzbare und auswechselbare Halbeinsätze 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 mit halbkreisförmigem Querschnitt zum Festklemmen des zugeführten Drahtes sowie eine daran anschließende Ausnehmung auf, die im geschlossenen Zustand der zwei gegenüberliegenden klemmbacken bzw. werkzeughalbeinsätze zur Anformung der gewünschten Kopfform des herzustellenden Teiles dient. Die Klemmbacken sind in der Maschine so angeordnet, daß sich die Spannrillen der paarweise eingesetzten Werkzeughalbeinsätze 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 Werkzeughalbeinsätzen in Form von 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 das Teil abgelängt und andererseits gleichzeitig die Ausgangsgeometrie zur Ausbildung des Kopfes des nächsten Teiles angeformt wird.Such half tool inserts are so-called striking or clamping jaws as well as lasting jaws, which are used in pairs in the machine in identical design. According to EP-A-0 401 918, the clamping jaws are often implemented and exchangeable Half-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 jaws have an or on an insert surface several clamping grooves with a semicircular cross-section for clamping the supplied wire and a subsequent one Recess on which in the closed state of the two opposing clamping jaws or half-tool inserts for shaping the desired head shape of the one to be produced Part serves. The clamping jaws are arranged in the machine so that the clamping grooves opposite the half-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 tool half-inserts in the form of lasting jaws. The jaws 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 pinch jaws are usually only single-core executed so that four in conjunction with two-core jaws Pinches are used.
Die Werkzeughalbeinsätze 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 half-tool inserts are often used to reduce wear Carbide made. Is the wear of the clamping grooves or the cutting edges bets must be exchanged.
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.Tungsten carbide and other hard, wear-resistant materials also show a high compressive strength a very high hardness and therefore high Wear resistance, but are in terms of tensile and Bending stresses only moderately resilient. Due to irregularities in wire quality fluctuating dimensions or different strengths it can the manufacture of nails, screws or rivets at very high levels Tensile stresses and thus excessive stresses on the inserts wear-resistant material come what often with a break of the inserts connected is.
Die EP-A-0 650 698 beschreibt ein Verfahren zur Herstellung von chirurgischen Nadeln, bei dem die Nadelspitze durch Umformen des drahtförmigen Ausgangs materiales, in einem entsprechenden Gesenk hergestellt wird. Um eine Formgebung des Gesenkes mit möglichst scharfkantigen übergängen, zur Ausformung einer möglichst spitzen und scharfkantigen Nadelspitze, zu erreichen, ist das Gesenk in Längsrichtung der Nadelspitze symmetrisch geteilt ausgeführt.EP-A-0 650 698 describes a method for producing surgical Needles, in which the needle tip is formed by reshaping the wire-shaped outlet material, is produced in a corresponding die. In order to shape the die with transitions that are as sharp as possible, to form a needle point that is as pointed and sharp as possible, the die can be reached in the longitudinal direction of the needle tip executed symmetrically divided.
Der Erfindung liegt die Aufgabe zugrunde, verschleißfeste Werkzeughalbeinsätze 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 Werkzeughalbeinsatz in Axialrichtung des zugeführten Drahtes geteilt ausgeführt ist. According to the invention this is achieved in that the half 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 lead to breakage of the insert, be avoided.
In einer vorteilhaften Variante der Erfindung sind die einzelnen Teile des Werkzeughalbeinsatzes durch eine Niet- oder Schraubverbindung miteinander verbunden.In an advantageous variant of the invention, the individual parts of the half tool insert are by a Rivet or screw connection connected to each other.
In einer anderen Variante werden die einzelnen Teile des Werkzeughalbeinsatzes über den Werkzeughalter bzw. über den Maschinenteil, in den sie eingesetzt werden, zusammengepreßt.In another variant, the individual parts of the half 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 with each other.
