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.

Embodiment

[0037] figure 1 Shown is the process flow of the method for generating the drawing die structure in this embodiment, including the following steps:

[0038] Step S10, establishing a drawing die structure standard template;

[0039] Step S20, defining product parting surface, parting line and wall thickness information;

[0040] Step S30, defining mold standard parts and their placement quantity and orientation in the mold according to product size specifications;

[0041] Step S40, reversely calculate the size of each part of the standard template through the product information and the standard part information;

[0042] In step S50, a drawing die structure is generated according to the reverse obtained standard template and standard part information.

[0043] In step S10, the standard template includes a punch part, a die part, a blank holder part and a formwork part, and the dimensions of each part are related to each other, and when a part of the size is changed, the as...
