Abstract

The embodiment of the invention discloses an all-cutting-edge knife flywheel which comprises a first knife flywheel disk surface, a second knife flywheel disk surface and a shaft hole, wherein the shaft hole is positioned at the center of the knife flywheel and extends along the transverse direction. The all-cutting-edge knife flywheel comprises a first curved surface and a second curved surface, wherein the first curved surface extends to the longitudinal center cross section of the knife flywheel along the outer edge of the first knife flywheel disk surface and forms smooth transition with the outer edge of the first knife flywheel disk surface; and the second curved surface extends to the longitudinal center cross section of the knife flywheel along the outer edge of the second knife flywheel disk surface, and forms smooth transition with the intersection line of the outer edge of the first knife flywheel disk surface. The intersection line of the first curved surface and the second curved surface at the longitudinal center cross section of the knife flywheel forms the circumferential cutting edge. The circumferential cutting edge is uniformly distributed with a groove. A groove inner cutting edge is arranged in the groove. According to the all-cutting-edge knife flywheel, the two side disk surfaces and the two curved surfaces for forming the circumferential cutting edge do not form sharp angles, thereby enhancing the impact resistance of the knife flywheel, lowering the friction area between the two side disk surfaces of the knife flywheel and the knife rest inner wall, and reducing the resistance in the knife flywheel rotation process.

Description

technical field [0001] The invention relates to the technical field of tool processing, in particular to a full-edge cutter wheel. Background technique [0002] With the diversified development of glass products, many production fields require glass to be thinner and harder, and the requirements for glass cutting quality are getting higher and higher. The tools for cutting glass are generally disk-shaped cutter wheels. The common features of the cutter wheels that have been used for a long time on the market are: they all include a cutting edge, a cutter wheel disk surface, and a shaft hole in the center of the cutter wheel for installing the cutter shaft. [0003] The cutting edge of the existing cutter wheel is in an inverted V shape, formed by the intersection of the first inclined plane and the second inclined plane, and the intersection line between the first inclined plane and the second inclined plane is the circumferential cutting edge of the cutter wheel. The first...
