Description
bandes legen sich die Ausleger 27,28 fest an die Laschen 29,30 an.band, the extension arms 27, 28 are firmly attached to the tabs 29.30 at.
Durch eine von der Rückseite des Maschinengehäuses her zu bedienende Spindel 31, deren Stirnseite beim Spannen des Sägebandes an einem unteren Ansatz 32 der Radaufnahme 19 zur Anlage kommt (Fig.4), läßt sich die Neigung des Sägebandes regulieren. Dies geschieht in der Regel so lange, bis das Sägeband auf Rad-Mitte läuftBy a spindle 31 to be operated from the rear of the machine housing, the end face of which at Tensioning of the saw band comes to rest against a lower extension 32 of the wheel mount 19 (FIG. 4) regulate the incline of the saw band. This usually happens until the saw blade is on Wheel center runs
Wie aus F i g. 2 hervorgeht ist das Sägeband 33 im Schneidbereich nach beiden Seiten und auf Sägedruck durch je eine gleiche Führungseinheit 34, 35 geführt. Dabei ist die eine Führungseinheit 34, unmittelbar unter dem Tisch 36 angeordnet und die andere, 35, höhenverstell- und arretierbar oberhalb des Tisches 36 angebracht. As shown in FIG. 2 shows the saw band 33 in the cutting area on both sides and at saw pressure guided by an identical guide unit 34, 35 each. One guide unit 34 is arranged directly under the table 36 and the other, 35, is height-adjustable. and lockably mounted above the table 36.
Wie aus F i g. 4 ersichtlich ist stützt sich der Halter 37 für die seitlich führenden, runden Gleitsteine 38 gegen Verdrehen an der Achse 39 des Lagers 40 ab, das den Sägedruck aufnimmtAs shown in FIG. 4, the holder 37 for the laterally leading, round sliding blocks 38 is supported against Turning on the axis 39 of the bearing 40, which absorbs the saw pressure
Alle diese Teile können leicht von vom oder von der rechten Seite her eingestellt werden. Das die oh:re Führungseinheit 35 tragende Führungsrohr 41 wird durch Einhandbedienung einer Sternschraube 42 an der Gehäuserückseite gelöst an dieser Schraube 42 auf die gewünschte Schnitthöhe eingestellt und wieder arretiert Die Schraube 42 bewegt sich dabei in einem Schlitz 43 im Maschinengehäuse 4. Das gefährliche Hochschieben mit der anderen Hand, die dabei in den Schnittbereich gelangt entfällt somit (siehe auch F ig. 2).All of these parts can easily be adjusted from the front or from the right side. That the oh: re management unit 35 supporting guide tube 41 is by one-handed operation of a star screw 42 on the rear of the housing loosened at this screw 42 adjusted to the desired cutting height and locked again The screw 42 moves in a slot 43 in the machine housing 4. The dangerous Push up with the other hand, which is in the The cutting area is therefore omitted (see also Fig. 2).
In ähnlicher einfacher Weise kann der Tisch 36 in jede gewünschte Position zwischen 0° und 45° geschwenkt und festgestellt werden. Die O°-Lage ist mittels einer justage 44 einstellbar. Die Genauigkeit beim Verschwenken ist durch zwei Führungsbolzen 45, 46 im Maschinengehäuse 4 gewährleistet Der Schlitz 47 im Tisch 36 zum Einlegen des Sägebandes 33 ist sehr genau und fest durch eine einfache Schraube 48 mit Mutter 48' verschließbar (F i g. 2).In a similarly simple manner, the table 36 can be pivoted to any desired position between 0 ° and 45 ° and be determined. The O ° position can be adjusted by means of an adjustment 44. The accuracy when pivoting is ensured by two guide pins 45, 46 in the machine housing 4 The slot 47 in the Table 36 for inserting the saw band 33 is very precise and fixed by a simple screw 48 with nut 48 ' lockable (Fig. 2).
Die quadratische Kunststoff-Tischeinlage 49 kann gegebenenfalls auch durch ein selbstgefertiges Holzteil ersetzt werden.The square plastic table insert 49 can optionally also be replaced by a self-made wooden part will.
Der Gehäusedeckel 50 ist an drei Punkten 51,52,53 befestigt und läßt sich einfach durch Drehen der zügehörigen Griffe um 90° anbringen bzv. abnehmen. Die Griffe 54 (F i g. 4) weisen federnde Teile 55 auf und rasten daher stets sicher und vibrationsfrei im Gehäusedeckei 50 ein. Sie bleiben immer am Maschinengehäuse 4 und müssen deshalb nicht mühsam ganz herausge- so dreht werden. Außerdem sind sie unverlierbar. Im Gehäusedeckel 50 ist sowohl aer Spänekanal 56 als auch der Staubsaugeranschluß 57 untergebracht (F i g. 1 und 2). Die Grundplatte der Bandsäge ist mit 58 bezeichnet.The housing cover 50 is at three points 51,52,53 attached and can be easily attached by turning the associated handles by 90 ° or. decrease. the Handles 54 (FIG. 4) have resilient parts 55 and therefore always lock securely and vibration-free in the housing cover 50 a. They always remain on the machine housing 4 and therefore do not have to be laboriously removed completely be rotated. In addition, they cannot be lost. In the housing cover 50 is both the chip duct 56 and the vacuum cleaner connector 57 housed (F i g. 1 and 2). The base plate of the band saw is labeled 58.
