在冲压书籍和设计手册中对排样的阐述特别是对排样方式、经济效果、排样与产量的关系、板材的纤维性对压弯件的影响以及塔边值等都有详细的论述和经验数据,它们对冲压加工的发展起了积极推动作用。然而,对抗剪强度较高,材料又较厚的金属板材,采取传统的逐个冲裁加工时,势必出现 In the stamping books and design brochures on the layout of the statement, especially on the layout, economic effects, the relationship between layout and yield, the sheet of the fiber on the bending of the value and the value of the tower are discussed in detail and Experience data, they have played a positive role in promoting the development of stamping process. However, the higher the shear strength, material and thick metal sheet, to take the traditional one by one punching process, is bound to appear
