Abstract
Bohrschraube mit einem Schneidteil (12), aufgebaut aus zwei Stirnschneien mit Freiflächen (122) und zwei Nebenschneiden mit Spannuten (121), die vier abgeschrägte Bereichen so angeordnet sind, dass sich jeweils eine auf je einer gegenüberliegenden Seite des Schneidteils (12) befindet, dadurch gekennzeichnet, dass zwischen der Spannut (121) und Freifläche (122) eine weitere Schneide (Schneidkante) und Freifläche (123) diagonal vorgesehen ist, so dass sechs Schneiden vorhanden sind.Bohrschraube with a cutting part (12), composed of two frontal snow with Open spaces (122) and two minor cutting edges with flutes (121), the four bevelled areas are arranged so that in each case one on each one opposite Side of the cutting part (12), characterized in that between the flute (121) and free surface (122) another cutting edge (cutting edge) and free surface (123) is provided diagonally, so that six cutting edges are present.
Description
Die Erfindung betrifft eine Bohrschraube mit sechs Schneiden, mit der nicht nur die Stärke des Aufbaus verbessert, sondern auch die Leistung beim Einbohren verbessert wird, und die somit eine innovative Ausführungsform darstellt.The The invention relates to a self-drilling screw with six cutting edges, with the not only the strength improved construction, but also the performance of drilling is improved, and thus an innovative embodiment represents.
Eine
Schraube mit Bohrspitze, d.h. eine Bohrschraube, kann für zahlreiche
Zwecke verwendet werden, vor allem beim Bau und bei der Konstruktion,
wo eine große
Menge von solchen Schrauben benötigt
wird. Die Kraft, mit der die Schraube am Materialaufbau befestigt
wird, hat einen direkten Einfluss auf die Qualität des Bauprojekts sowie auf
die Ausführungszeit
des Projektes. Wie in
Zusätzlich sind

Angesichts dieser Nachteile der herkömmlichen Bohrschrauben soll mit der vorliegenden Erfindung eine verbesserte Bohrschraube geschaffen werden.in view of these disadvantages of conventional Self-drilling screws should be improved with the present invention Drilling screw to be created.
Diese Aufgabe ist durch die Erfindung bei einer Bohrschraube mit den Merkmalen des Anspruchs 1 gelöst.These Task is by the invention in a drill with the features of claim 1.
Eine erfindungsgemäße Bohrschraube bzw. ein Bohrkopf zeichnet sich somit durch das besondere Merkmal der abgeschrägten Klinge im Schneidteil mit einem Schlitz aus, der als Schlitz aufgeweitet ist, um die Geschwindigkeit beim Schneiden zu verbessern.A drilling screw according to the invention or a drill head is thus characterized by the special feature the beveled Blade in the cutting part with a slot that widens as a slot is to improve the speed of cutting.
Die Mulde mit dem Schlitz ist exzentrisch ausgeführt, so dass auch der Winkel der abgeschrägten Klinge bzw. Schneide exzentrisch ist. Beim Bohren und Schneiden wird der Bohrwinkel wegen der Mulde mit dem Schlitz mit einer bestimmten Tiefe und wegen dem ausgeübten Druck zwangsläufig beeinflusst, wobei die meiste Kraft auf die Bohrspitze ausgeübt wird. Diese kann dadurch leicht beschädigt werden.The Trough with the slot is eccentric, so that the angle the beveled Blade or cutting edge is eccentric. When drilling and cutting the drilling angle is due to the trough with the slot with a certain Depth and because of the exercised Pressure inevitably influenced, with most of the force is exerted on the drill bit. This can easily be damaged.
Durch die vorliegende Erfindung wird der Schneidteil mit zwei Schneiden mit zwei diagonalen Schneidwinkeln ausgestattet, um eine Schneidvorrichtung mit sechs Schneiden zu bilden. Mit diesen beiden scharfen Schneiden wird auch ohne lange und tiefe Schneide zum Einschneiden eine scharfe Schneidstelle geschaffen. Der Schneidteil hat daher einen vorbestimmten Durchmesser und eine bestimmte Bohrstärke, wobei der Drehpunkt stets gut vor Augen gehalten wird.By The present invention will be the cutting part with two cutting edges equipped with two diagonal cutting angles to a cutting device to form with six cutting edges. With these two sharp edges is a sharp cutting point even without a long and deep cutting edge created. The cutting part therefore has a predetermined diameter and a certain drill bit, where the fulcrum is always well kept in mind.
Die Erfindung wird im folgenden weiter anhand eines bevorzugten Ausführungsbeispiels und der Zeichnung beschrieben. In der Zeichnung zeigen:The Invention will be further described below with reference to a preferred embodiment and the drawing. In the drawing show:
