摘要:
|
作者对锻压机上模锻常用的制坯工艺——制坯辊锻中大型辊坯椭网型槽的设计进行了探讨。指出目前常用的延伸系数与轴长比及延伸系数与压下量关系的公式、图表不适合于大型辊坯的制坯辊锻设计,必须建立符合大型辊坯实际的延伸系数与轴长比或延伸系数与压下量的关系;推导出了椭圆型槽几何参数之间的关系公式;初步建立了大型辊坯椭圆型槽的设计方法,可供大型辊坯辊锻设计时参考。

Roll forging is the main preforming operation for press forging. The technological parameters of the elliptical cavities for the large roll forging have been discussed because the usual functions and data are not suitable for the large roll forging, which stock is large in section and in length. The relational functions between the geometric parameters have been derived, which can be used to calculate precisely. A method for designing the elliptical cavities of the large roll forging has been developed. The formulas and method suggested by author provide a guidance for practical application.
