Document Type and Number:
WIPO Patent Application WO/2017/113041
Kind Code:
A1
Abstract:
A TCT clamped cemented carbide circular saw blade, comprising a saw blade body (1) and toothed holders (8) having blades (2) mounted thereon. A radial positioning elevation (9) of the toothed holder (8) that matches the blade (2) is provided with a positioning protrusion or positioning groove (3). The blade (2) is provided with a groove or protrusion (5) matching the positioning protrusion or positioning groove (3) on the toothed holder (8). The toothed holder (8) is provided with a threaded hole (4), in which a fastening screw (7) is mounted. An angle between the center line of the threaded hole (4) and the positioning elevation (9) ranges from 45° to 90°. As compared with the prior art, in the TCT clamped cemented carbide circular saw blade, the fastening screw and the blade constitute an oblique fastened construction, thereby reducing the difficulty in machining by using the blades and the saw blade body and implementing easy and quick installation.
