Description

Betonbrechzange  Concrete-crushing pincers
Die vorliegende Erfindung bezieht sich auf eine Betonbrechzan- ge . The present invention relates to a Betonbrechzan- ge.
Aus dem Stand der Technik sind Betonbrechzangen in Gestalt einer Kastenschere bekannt. Derartige Betonbrechzangen haben Zangenbacken mit scharfen Ecken im distalen Bereich, und die Concrete crushing pincers in the form of a box scissors are known from the prior art. Such concrete pincers have pliers jaws with sharp corners in the distal area, and the
Schneidkanten sind in einer Seitenansicht im Wesentlichen in einer Ebene angeordnet. Es hat sich bei diesen Betonbrechzangen gezeigt, dass der Verschleiß im Bereich der Ecken weit überproportional erhöht ist. Dort treten lokal sehr hohe mechanische Spannungen auf. Konstruktiv sind die Ecken selbst steif, die angrenzenden Wände am Kasten sind jedoch weicher, woraus ein ungleichmäßiger Schnittspalt mit schlechten Schnittergebnissen resultiert . Cutting edges are arranged in a side view substantially in a plane. It has been shown in these concrete pincers that the wear in the area of the corners is disproportionately increased. There occur locally very high mechanical stresses. Constructively, the corners themselves are stiff, but the adjacent walls on the box are softer, resulting in an uneven kerf with poor cutting results.
Aus der WO 96/02708 A ist eine andere Betonbrechzange gemäß dem Oberbegriff von Anspruch 1 bekannt. Diese Betonbrechzange hat eine erste Zangenbacke, die einen rahmenartigen ersten Grundkörper aufweist, der einen Innenraum der ersten Zangenbacke definiert und eine erste Schneidkante aufweist, und eine zweite Zangenbacke, die eine zweite Schneidkante aufweist und mit der ersten Zangenbacke um eine Gelenkachse schwenkbar verbunden ist, um in den Innenraum einzutauchen. Die erste Schneidkante besteht aus zwei Schenkeln, die im Wesentlichen spiegelsymmetrisch zu einer Mittelachse verlaufen, die senkrecht zur Gelenkachse steht. Die Schenkel bilden des Weiteren einen distalen Endabschnitt in Gestalt einer geraden Kante. Die Mittelachse schneidet die Gelenkachse und den distalen Endabschnitt. Die Schenkel bilden in einer Draufsicht ein U-förmiges Profil, das an den Ecken mit konstantem Krümmungsradius leicht abgerundet ist. Diese Betonbrechzange hat nicht die Nachteile der eingangs erwähnten Kastenscheren, sie ist jedoch relativ aufwändig herzustellen . Es ist daher die Aufgabe der vorliegenden Erfindung, eine Betonbrechzange vorzusehen, die für einen gleichmäßigen Schnittspalt sorgt und die einfacher herzustellen und gleichzeitig haltbar ist . Diese Aufgabe wird durch die Betonbrechzange mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der vorliegenden Erfindung sind in den Unteransprüchen angegeben. From WO 96/02708 A another Betonbrechzange according to the preamble of claim 1 is known. This concrete crusher has a first jaw having a frame-like first base defining an interior of the first jaw and having a first cutting edge, and a second jaw having a second cutting edge and pivotally connected to the first jaw about a hinge axis to immerse in the interior. The first cutting edge consists of two legs, which are essentially mirror-symmetrical to a central axis, which is perpendicular to the hinge axis. The legs further form a distal end portion in the form of a straight edge. The central axis intersects the hinge axis and the distal end portion. The legs form a U-shaped profile in a plan view, which is slightly rounded at the corners with a constant radius of curvature is. This concrete pincers does not have the disadvantages of the aforementioned box scissors, but it is relatively expensive to produce. It is therefore the object of the present invention to provide a concrete pincers, which ensures a uniform cutting gap and which is easier to manufacture and at the same time durable. This object is achieved by the Betonbrechzange with the features of claim 1. Advantageous developments of the present invention are specified in the subclaims.
In Untersuchungen, die zur vorliegenden Erfindung führten, wur- de die Betonbrechzange aus der WO 96/02708 A in mehreren Stufen weitergebildet. Zunächst wurden die Eckradien mit verschiedenen, weiteren Radien anstatt mit einer Geraden verbunden, so dass ein kontinuierlicher Bogen entstand, der das Problem des ungleichmäßigen Schneidspalts weitgehend eliminierte. Dies hat zu weiteren Überlegungen geführt, um die Bogenform zu optimieren. Insbesondere wurden bekannte, mathematisch definierte Bögen mittels FEM Analyse untersucht, nämlich eine Ellipse, ein Klöpperbogen nach DIN 28011 und ein Korbbogen nach DIN 28013. Im Dünnblechbereich funktionieren die beiden letztgenanntenIn investigations leading to the present invention, the concrete pincers from WO 96/02708 A were further developed in several stages. First, the corner radii were connected with different, wider radii instead of a straight line, so that a continuous arc was created, which largely eliminated the problem of uneven cutting gap. This has led to further considerations to optimize the bow shape. In particular, known, mathematically defined sheets were examined by means of FEM analysis, namely an ellipse, a dished bow according to DIN 28011 and a basket bow according to DIN 28013. In thin sheet metal work the latter two
Formen gut, der Schnittspalt kann jedoch noch weiter optimiert werden. Die Ellipse zeigt einen besseren Schnittspalt, ist aber in der Herstellung aufwändiger. Shapes well, but the kerf can be further optimized. The ellipse shows a better cutting gap, but is more complex to manufacture.
Die besten Ergebnisse konnten erzielt werden, wenn die Betonbrechzange gemäß Anspruch 1 ausgebildet wird. Die Vorteile der Betonbrechzange sind ein gleichmäßiger Kraftlinienverlauf, ein konstantes Spannungsniveau im Bauteil, ein gleichmäßiger Schneidspalt bei einem ziehenden Schnitt, weniger und gleichmäßigerer Verschleiß, leichteres und kostengünstige- res Schärfen, eine leichtere Bauweise der gesamten Betonbrechzange und eine Trennung der Brechzone, sofern Zähne vorgesehen sind. The best results could be achieved when the concrete crushing tongs is formed according to claim 1. The advantages of the concrete pincers are a uniform line of force, a constant stress level in the component, a uniform cutting gap with a pulling cut, less and more uniform wear, easier and less expensive sharpening, a lighter construction of the entire concrete pincers and a separation of the crushing zone, if provided are.

Schneidkante 5 passiert, um den dazwischenliegenden Beton zu scheren. Die zweite Schneidkante 7 ist im Wesentlichen an. die Form der ersten Schneidkante 5 angepasst; sie ist aber kleiner, da sie in den Innenraum 4 eintaucht. Cutting edge 5 happens to shear the intervening concrete. The second cutting edge 7 is substantially on. adapted the shape of the first cutting edge 5; but it is smaller because it dips into the interior 4.
Die Fig. 6 zeigt in einer Draufsicht (in der xy-Ebene) den Ver- lauf der ersten Schneidkante 5 der ersten Zangenbacke 2 der Betonbrechzange 1 gemäß dem Ausführungsbeispiel der vorliegenden Erfindung.

Der Verlauf des Schneidkantensegments in der Draufsicht wird durch bestimmte geometrische Figuren folgendermaßen definiert. According to FIG. 6, the legs 9, 10 of the first cutting edge 5 in a plan view perpendicular to the hinge axis 8 and perpendicular to the central axis 11 each have a cutting edge segment with a non-constant radius of curvature. The course of the cutting edge segment in plan view is defined by certain geometric figures as follows.
Zunächst wird eine virtuelle Viertelellipse durch eine große Halbachse a, die parallel zur Gelenkachse 8 der Betonbrechzange 1 verläuft, und eine kleine Halbachse b definiert, die am distalen Endabschnitt 12 der ersten Schneidkante 5 endet. Die kleine Halbachse b verläuft also zwischen einem Mittelpunkt M der virtuellen Viertelellipse und dem distalen Endabschnitt 12 der ersten Schneidkante 5. First, a virtual quarter ellipse is defined by a large semiaxis a, which runs parallel to the articulation axis 8 of the concrete crushing tongs 1, and a small semiaxis b, which ends at the distal end portion 12 of the first cutting edge 5. The small semiaxis b thus extends between a center M of the virtual quarter ellipse and the distal end portion 12 of the first cutting edge 5.
Daneben werden ein virtueller, halber Klöpperbogen nach DIN 28011 und ein virtueller, halber Korbbogen nach DIN 28013 jeweils mit einem Radius ra, einer Kallote rl, einer Krempe r2 und einem Bord h definiert, wobei der Radius ra identisch zu der großen Halbachse a der virtuellen Viertelellipse ist und wobei Enden oder Spitzen (entsprechend den Hochpunkten des gan- zen Klöpperbogen oder des ganzen Korbbogens) des virtuellen, halben Klöpperbogens und des virtuellen, halben Korbbogens jeweils auf dem Schnittpunkt der Viertelellipse mit dem distalen Endabschnitt 12 liegen und der Bord h an der großen Halbachse a endet . In addition, a virtual, half dished bow according to DIN 28011 and a virtual, half basket bow according to DIN 28013 are each defined with a radius ra, a Kallote rl, a brim r2 and a board h, wherein the radius ra identical to the large semi-axis a of the virtual Quarter ellipse is and where ends or tips (corresponding to the high points of the whole dipper bow or the whole basket bow) of the virtual, half dovetail and the virtual, half basket arch respectively at the intersection of the quarter ellipse with the distal End portion 12 lie and the board h ends at the large semi-axis a.
