Provided is a miter saw. The miter saw includes a first locking mechanism, where when the first locking mechanism is in a first state, a cutting mechanism is fixed relative to a workbench, when the first locking mechanism is in a second state, the cutting mechanism is allowed to rotate relative to the workbench, when the first locking mechanism is in a third state, the rotation of the cutting mechanism relative to the workbench is positioned, and the first locking mechanism includes a first operation member for switching the first state, the second state, and the third state of the first locking mechanism. The miter saw is easy and convenient to operate.

The present invention discloses an angle clearance-free welding method for uPVC doors and windows, which is used for welding a welding angle formed by assembly of a left side welding unit and a right side welding unit, wherein opposite assembly inner side faces of the left side welding unit and the right side welding unit are cut surfaces; before the left side welding unit and the right side welding unit are welded, the outer surface of the outer contour of each of the cut surfaces needs to be milled off inward by using a cutting saw for a width of 1-4mm and a depth of 1.5-3mm to form a groove on the outer surface of the outer contour, so that a material fused by welding of the cut surfaces in a welding process does not overflow to the surface and is retained in the groove, no angle clearance is necessary after welding, a seamless splicing effect is achieved, and seamless butt joint of the patterns is achieved particularly for the welding of section bars with natural wood grains and patterns on the surfaces. Meanwhile, the present invention further discloses a double-head cutting saw used for cutting an end face and an end face contour in the above process.

Zur Bildung einer winkelförmigen Ausnehmung in einem dünnwandigen Profilstab sind zwei Sägen mit rotierenden Sägeblättern vorgesehen. Die Sägen sind dabei so ausgerichtet, daß die Sägeblätter den Schnitt zur Bildung der einen bzw. anderen Seite der winkelförmigen Aussparung in den Profilstab durchführen. Die Sägen sind in Schlittenbewegungsrichtung hintereinander angeordnet, wobei die beiden Sägeblätter zur Bildung einer gemeinsamen Schneidlinie eine gemeinsame, parallel zur Schlittenbewegungsrichtung verlaufende Tangente aufweisen.

Die Erfindung betrifft eine Klinkschnittsäge mit zwei Sägeaggregaten (14,24), die, je nach vorgegebenem Klinkschnitt, unabhängig voneinander an einem gemeinsamen Gestell (2) einstellbar angeordnet sind. Um zu erreichen, daß die Sägeaggregate (14,24) der Klinkschnittsäge (1) schnell und genau einstellbar sind, und zwar auch dann, wenn ein Klinkschnitt in verschiedenen Positionen durchgeführt werden muß, schlägt die Erfindung vor, die beiden Sägeaggregate (14,24) jeweils an einem Schwenkarm (8,22) zu befestigen, wobei die beiden Schwenkarme (8,22) um die Längsachse (6) eines gemeinsamen Lagers (5) des Gestells (2) schwenkbar angeordnet sind. Außerdem ist vorgesehen, die beiden Schwenkarme (8,22) form- und/oder kraftschlüssig miteinander verbindbar anzuordnen, so daß beide Sägeaggregate (14,24) um die Längsachse (6) des Lagers (5) auch gemeinsam verschwenkbar sind.
摘要:
An apparatus for mounting a device, such as a saw blade, on a base (3) to enable the blade to be positioned accurately in either of two distinct positions relative to the base. The apparatus comprises a pivot member (21) for supporting the blade (not shown) pivotally mounted on a fixed member (11). The fixed member (11) includes a pair of abutments (142,144) and the pivot member has at least one asymmetric stop (160) for abutting the abutments (142,144) after rotation of the pivot member (21) relative to the fixed member to define the distinct positions of the blade. These positions are defined generally by the positions of the abutments (142,144) and accurately by the orientation of the or each asymmetric stop (160). The apparatus may further include a device (170) for adjusting accurately one of the distinct positions by a predetermined amount.
