Deep drawing die structure generating method and system

Abstract

The invention discloses a deep drawing die structure generating method and system. According to the technical scheme, a deep drawing die standard template is established, a product parting surface, aparting line and wall thickness information are defined; according to product sizes and specifications, die standard parts and the placing quantity and orientation of the die standard parts in a die are defined; through product information and standard part information, sizes of all parts of the standard template are reversely solved; through the product information, sizes of a convex die portion,a concave die portion and an edge pressing portion of the standard template are determined; according to the placing position of the standard part and the product information, the size of a die baseis determined, and then the size of the whole die frame portion is determined; according to the reversely solved standard template and the standard part information, a deep drawing die structure is generated; the deep drawing die structure comprises the reversely solved standard template, the product parting surface, the parting line and the selected standard parts. The drawing line structure generating method and system help shorten the design cycle of the deep drawing die and increase the standardization degree of the deep drawing die.

Description

technical field [0001] The invention relates to the field of mold design and manufacture in mechanical engineering, in particular to a method and system for generating a drawing mold structure. Background technique [0002] Deep drawing dies are widely used in automobiles, home appliances and other fields, and die structure design is a very important stage in the entire die production cycle, which directly affects die manufacturing, assembly process and die life. [0003] The traditional deep drawing die structure design is mainly based on the experience of the designer. According to the shape and size of the part, the structure and size of each part of the die are determined by consulting the die design standards and standard parts manual, and then the parts of the die are individually designed by CAD software , and finally assemble the designed parts together to complete the design of the overall structure of the mold. [0004] Structural design through traditional method...

AI Technical Summary

Problems solved by technology

[0004] Structural design through traditional methods relies heavily on the experience of the designer, which is not only inefficient, but also has defects such as unreasonable mold structure and insufficient strength due to the lack of experience of the designer

[0005] When designing the mold structure, it is often necessary to change the size and structure of each part of the mold according to the process conditions of the parts. The traditional method can only manually change the parts that need to be changed one by one. The change process is time-consuming and laborious, and the degree of standardization is low.
