冲压加工中产生毛刺最明显的工序是冲裁。冲裁为冲压加工的第一道工序,应用最广泛,其质量对后道工序有着重要的影响,因此极大地左右着最终成品的性能。为掌握有关形成毛刺的知识,必须充分了解影响冲裁过程及冲裁特性的各种因素与冲裁特性值的关系。图1所示为冲裁过程中各部位的名称和符号。d表示毛刺的高度,而压痕宽度g,倾角δ,断裂面
Stamping process burr generated the most obvious process is blanking. Blanching as the first stamping process, the most widely used, the quality of the latter process has an important impact, it greatly affects the performance of the final product. In order to grasp the knowledge about the formation of burrs, it is necessary to fully understand the relationship between the various factors that affect the blanking process and the blanking characteristics and the blanking characteristics. Figure 1 shows the name and symbol of the various parts of the blanking process. d said burr height, and indentation width g, angle δ, fracture surface
