本文主要讨论和分析新型双滚筒式碎边剪的刀刃曲线形成原理,刀刃曲线的形状分析,并推导出刀刃曲线方程式。通过对剪切过程的特点分析,导出了剪切过程中剪切点处的刀刃倾角α和曲率半径ρ的计算公式。最后讨论了叶边剪的主要结构参数:刀刃圆周直径D_0,刀刃数目,刀刃倾角(?)等的选择,为今后的设计提供了较可靠的依据。
This article mainly discusses and analyzes the formation principle of blade edge curve, the shape analysis of blade edge, and derives the blade edge equation. Through the analysis of the characteristics of the shearing process, the formula of blade inclination angle α and radius of curvature ρ at the shear point during shearing is deduced. Finally, the main structural parameters of blade shear are discussed: the choice of cutting edge diameter D_0, the number of cutting edges and cutting edge inclination (?) Provides a more reliable basis for the future design.
