Abstract
Stichsäge (10) mit einem am unteren Ende einer Hubstange (20) gehaltenen, an gehäusefest angeordneten Stützmitteln (27, 30, 31) geführten Sägeblatt (22) mit einem Sägeblattrücken (24) sowie Flachseiten (41, 42), dadurch gekennzeichnet, daß die Stützmittel (27, 30, 31) aus einer einstückigen Profilrolle (27) bestehen, deren Profil den Sägeblattrücken (24) sowie die Flachseiten (41, 42) nahe deren Mitte abstützend umgreift.Jigsaw (10) with a at the lower end of a lifting rod (20) held on to the housing arranged proppants (27, 30, 31) Saw blade (22) with a saw blade back (24) and flat sides (41, 42), characterized in that the support means (27, 30, 31) from a one-piece Profile roll (27) consist, the profile of the saw blade back (24) and the flat sides (41, 42) supporting near their middle embraces.
Description
Die Erfindung geht aus von einer Stichsäge nach der Gattung des Anspruchs 1.The The invention is based on a jigsaw according to the preamble of the claim 1.
Durch
die
Bei anderen Stichsägen ist es bekannt, den Sägeblattrücken oberhalb der Grundplatte in der umlaufenen Nut einer Führungsrolle zu führen und abzustützen. Dadurch sollen beim Sägen das untere Hubstangenlager und die Spannmittel zum Halten des Sägeblatts frei von Schwingungen und Biegekräften gehalten werden.at other jigsaws It is known the saw blade back above to guide the base plate in the circumferential groove of a guide roller and support. This should be sawing the lower Hubstangenlager and the clamping means for holding the saw blade be kept free of vibrations and bending forces.
Dadurch, daß das Sägeblatt mit seinem Rücken nahe der Grundplatte – und damit nahe dem Werkzeugeingriff im Werkstück – abgestützt wird, ist das Sägeblatt nicht über seine volle Länge zwischen Sägeblattspitze und Einspannende, sondern nur zwischen Sägeblattspitze und der Führungsrolle verbiegbar. Dies erhöht die Steifigkeit des Sägeblatts.Thereby, that this sawblade with his back near the base plate - and in order to be supported near the tool engagement in the workpiece, the saw blade is no over his full length between saw blade tip and clamping end, but only between the saw blade tip and the guide roller bendable. This increases the stiffness of the saw blade.
Bisher sind die den Sägeblattrücken führenden Rollen mit einer V-Nut bzw. mit einer flachen U-Nut versehen, wobei sich der Sägeblattrücken nur mit seinen beiden Außenkanten an den Nutflanken bzw. Schrägflächen abstützt und dadurch verhältnismäßig leicht quer zur Vorschubrichtung verbiegbar und um seine Längsachse verdrehbar ist. Dadurch ist es unmöglich, mit den bisherigen Stichsägen qualitativ so gute Arbeitsergebnisse wie beispielsweise mit Kreissägen zu erzielen. Mit herkömmlichen Stichsägen gesägte Schnittkanäle verlaufen, einfach ausgedrückt, zickzack- bzw. S-förmig.So far are the leading the saw blade backs Rolls provided with a V-groove or a flat U-groove, wherein the saw blade back only with its two outer edges supported on the groove edges or inclined surfaces and relatively easy Bendable transversely to the feed direction and about its longitudinal axis is rotatable. This makes it impossible to qualitatively with the previous jigsaws To achieve such good work results as for example with circular saws. With conventional jigsaws sawn section channels run, in simple terms, zigzag or S-shaped.
Bei weiteren Stichsägen sind in der Grundplatte am Durchtrittsschlitz des Sägeblatts seitliche Gleitflächen angeordnet, an denen sich bei einer bestimmten seitlichen Auslenkung das Sägeblatt seitlich gut stabilisiert abstützt, wobei die Gleitreibung eine entsprechend hohe Abnutzung des Sägeblatts und zusätzlich zur sägebedingten Erwärmung hohe Wärmeentwicklung bis hin zum Ausglühen sowie Säge-Leistungsverlust hervorruft.at further jigsaws are in the base plate at the passage slot of the saw blade lateral sliding surfaces arranged at which at a certain lateral deflection the saw blade supports well stabilized laterally, the sliding friction a correspondingly high wear of the saw blade and additionally to saw-related warming high heat development to the annealing as well as sawing power loss causes.
Vorteile der ErfindungAdvantages of invention
Die erfindungsgemäße Stichsäge mit den kennzeichnenden Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, daß das Sägeblatt deutlich besser geführt ist als mit den bisher verwendeten Rollen, d.h. so stabil wie mit Gleitflächen, ohne deren nachteilige Reibung. Dadurch sind mit der erfindungsgemäßen Stichsäge Geradschnitte in annähernd Handkreissägenqualität erreichbar.The jigsaw according to the invention with the characterizing Features of claim 1 has the advantage that the saw blade much better run is than with the previously used roles, i. as stable as with sliding surfaces, without their adverse friction. As a result, straight cuts are made with the jigsaw according to the invention in approximate Hand-held circular saw quality achievable.
Die Lebensdauer der Stichsägeblätter bei Verwendung in der erfindungsgemäßen Stichsäge wird durch die geringere Biegung und Torsion vor allem aber durch Vermindern der Wärmeent wicklung durch Reibungsverringerung deutlich erhöht. Außerdem ist die Arbeitsleistung mit der erfindungsgemäßen Stichsäge durch den exakt geradlinigen und damit schmaleren und kürzeren Schnittkanalverlauf höher als bei bisherigen Stichsägen.The Life of the jigsaw blades when used in the jigsaw according to the invention due to the lower bending and torsion but above all by reducing the development of heat Friction reduction significantly increased. In addition, the work performance with the jigsaw according to the invention the exact straight-line and thus narrower and shorter cutting channel course higher than in recent jigsaws.
Aufgrund der exakt geraden und damit schmaler und kürzeren Schnittkanäle wird eine geringere Spanmenge abgetragen und weniger Energie verbraucht, so daß die Umweltbelastung geringer wird.by virtue of the exact straight and thus narrower and shorter cutting channels a smaller amount of chip removed and consumes less energy, So that the Environmental impact is lower.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.Further advantageous embodiments of the invention will become apparent from the dependent Claims.

Bei einem nicht dargestellten Ausführungsbeipiel der Erfindung besteht die Profilrolle aus zwei sich symmetrisch zur Rollenmitte axial aneinander abstützenden, spiegelbildlich zueinander angeordneten Profilscheiben, wobei das Profil etwa die Gestalt eines O-Ringes hat. Außerdem ist der Lagerbock elastisch in Pendelrichtung des Sägeblatts verbiegbar, so daß er der Pendelbewegung des Sägeblatts folgen kann.at a Ausführungsbeipiel, not shown the invention, the profile roller consists of two symmetrical to the center of the roll axially abutting each other, mirror images of each other arranged profiled disks, wherein the profile is approximately the shape of a O-ringes has. Furthermore the bearing block is elastic in pendulum direction of the saw blade bendable, so that he follow the pendulum movement of the saw blade can.
