在模具结构设计中的典型非标准零部件的精度设计

摘要

This paper uses a typical non-standard parts as an example in the design, processing, manufacturing of die structure, references to "national standards", describes the typical die structure design of non-standard parts precision design theory with practical methods. According to the functional requirements of the die structure,it is to precision design the nonstandard parts in the die structure, as well as the accurate determination of the dimensional accuracy, shape, position accuracy and the surface roughness parameter values, and the components combined with the selection and labeling of the co-ordination between the surface of the abbreviations. And as the accumulated experience of non-standard parts precision in the die structure design.%以模具结构中的典型非标准零部件为例，参照《国家标准》，用理论联系实际方法介绍了在模具结构设计中的典型非标准零部件的精度设计。依据模具结构的功能要求，进行模具结构中的非标准零部件精度设计，以及准确的确定尺寸精度、形状位置精度和表面粗糙度参数值、零部件相结合表面间的配合代号的选择和标注，以此作为在模具结构设计中的非标准零部件精度的经验积累。
