Fully parametric drawing mould design method

Abstract

The invention discloses a fully parametric drawing mould design method, which enables the design of a mould structure to be more reasonable and realizes the parameterization, the high speed and the intellectualization of the drawing mould design process. The invention has the technical scheme that the method comprises the following steps of stamping process pretreatment: processing process data, and directly obtaining a mould structure design element by combining with a mould design standard; mould structure design: aiming at the design of the non molded surface part of a model to carry out associated design to a mould structure parameter during solid modeling so as to bring convenience for the model to automatically change when a corresponding parameter is changed.

Description

technical field [0001] The invention relates to the structural design of stamping dies, in particular to the design method of the die structure applicable to the outer cover parts of all new car models. Background technique [0002] The drawing die is the first process of the stamping die of the cover part. It is used to realize the main characteristics of the part and is the most important link. [0003] Under normal circumstances, the design of the drawing die structure is based on the die design standard, starting from scratch according to the stamping process of the part. This common design method has the following shortcomings: [0004] (1) The degree of standardization of this method of modularization of local structure design is not high, and a large number of calls and assemblies are required in CAD software during design, which is of limited help to shorten the design cycle, and when the stamping process changes, the mold structure is updated It is very difficult a...

Problems solved by technology

[0004] (1) The degree of standardization of this method of modularization of local structure design is not high, and a large number of calls and assemblies are required in CAD software during design, which is of limited help to shorten the design cycle, and when the stamping process changes, the mold structure is updated It is very difficult and needs to be replaced manually, which is time-consuming and laborious;

[0005] (2) The design cycle is long, the degree of standardization is low, and the similar structures of different parts are repetitive, which may easily lead to unreasonable structural design and the need for multiple revisions during the design process.
