1、外文原文 Abstract： Die designing is a demanding and hard work To design a separate die for each product is time consuming and expensive task This paper presents an idea of sets of standard reference dies it gives a concept of flexible die designing using a reference standard die designed in a popular co
2、mmercial CAD CAM software Pro Engineer Rather than designing a separate die for each part， just update the die design by selecting the die dimensions as required The use of this concept will prove to reduce time and cost of product in manufacturing industry Key words： die； flexible die designing sys
3、tem ； standardization； Pro/E； secondary development At present, the industrial developed countries and regions in the mold industry has been gradually standardize and serialization. In China, although the majority die within the enterprises have business standards, but generally not high degree of s
4、tandardization, standardization of stamping die in the die-limited parts of the parts. To achieve real savings stamping die design time and shorten the processing cycle, cost savings, reduce design and manufacturing staff workload purposes, it needs to develop a flexible stamping die design system.
5、At the same time, stamping die serialization of the scope of standardization and can not be confined to die-part of the fixed panels, boards, the top plate unloading device commonly used components such as stamping or even die structure, we should achieve serialization and standardization. As CAD /

The use of the former first family table to create a generic representation of the components (the generic), according to the need to target and then added to the family table a series
10、of management. Family sheet management can be the object of a size (dimension), features (feature), parameters (parameter) and assembly parts (component), and so on. A family table can have multiple levels, that is a generic parts can contain multiple sub-components (instance, also known as examples
11、), and each Instance can contain their own Sub Instance. Discharge screw (stripper-bolt) the family table structure as shown in Figure 1.

The typical model-there are three types: rear-guided-mode (back pillar sets), the middle-guided-mode (center pillar sets) an

As three categories-the larger structural differences, it may die-the root of the establishment of three other subdirectories, each subdirectory contains all the component parts-mode, and each type of parts can be adopted Pro / E Software for the family table, and tools
