Cutter wheel for cutting brittle materials

一种脆性材料切割刀轮

Abstract

The invention relates to the field of cutters for cutting brittle materials, and provides a cutter wheel for cutting brittle materials. The cutter wheel comprises a wheel body and a plurality of wheel teeth. The wheel teeth are formed on the wheel, each wheel tooth comprises a first auxiliary edge, a main edge and a second auxiliary edge which are sequentially connected with one another and are coplanar; certain oblique planes, which are positioned on the same side of a plane where the main edge, the first auxiliary edge and the second auxiliary edge of each wheel tooth are positioned, and among oblique planes for forming the main edge, the first auxiliary edge and the second auxiliary edge of the wheel tooth, are sequentially connected with one another; a sunken region is formed between the main edges of every two adjacent wheel teeth in the wheel, and the first auxiliary edges and the second auxiliary edges are positioned in the sunken regions. The cutter wheel has the advantages that the uniform continuity of cut lines can be enhanced, cutting breaking properties of the brittle materials can be improved, the cutting yield of the brittle materials can be increased, and accordingly, the mechanical strength of cut edge regions of brittle material products can be improved, and the service stability of the products can be improved.
本发明涉及脆性材料切割刀具领域,提供了一种脆性材料的切割刀轮,包括轮体以及形成于轮体上的多个轮齿,其中,每一个轮齿包括依次相连的第一副刃、主刃和第二副刃,其中,主刃、第一副刃、第二副刃共平面,且用于形成所述第一副刃、主刃和第二副刃的斜面中,位于所述主刃、第一副刃和第二副刃所在平面同一侧的斜面依次连接;轮体中,每相邻的两个轮齿的主刃之间形成一个凹陷区域,第一副刃和第二副刃位于凹陷区域内。该切割刀轮可增强切割线的均匀连贯性,提高脆性材料的切割的分断性和切割良品率,从而提高了脆性材料产品切割边缘区域的机械强度,进而提高了产品的使用稳定性。
