Abstract
This article discusses the design of the non-pressure side of the conical ring mold tensile mold,through the analysis of the tensile mechnical parts forming process. The design of the mold determines the main stretch of the die drawing process to identify and structure, including the rough size of the mechnical parts, calculation of coefficient of the mechnical parts, as well as the calculation of tensile stretching coefficient number and size of the identified process, the process of stretching and stretching Blankholder force calculation, The choice of mold material (see parts drawings), molding parts, structural parts form the structure (mainly the punch die and the main dimensions of choice and the calculation). The programm Pro/E was used for the three-dimensional shape of product. This article by the tooling design is simple in structure, movement reliable, cost-saving advantages, in particular.This paper takes full advantage of modern CAD design software, CAD design software demonstrated in the mold design capabilities in a good.
