Embodiment 1

[0053] A method for controlling the stamping quality of a large cover, the method comprising the following steps:

[0054] S1. Establish CAD model:

[0055]Establish a CAD (abbreviation for Computer Aided Design, translated as computer-aided design) model of the corresponding cover according to the prototype of the cover or the drawing of the cover;

[0056] S2. Add relevant supplementary processes to the CAD model:

[0057] According to the actual situation and subsequent mold manufacturing-related restrictions, some process supplements are made to the CAD model. Reasonable process supplements make the stamping parts easy to form, especially for the formation of special shapes;

[0058] S2. Supplement or modify related processes to the CAD model:

[0059] Supplement or modify the relevant process of the CAD model according to the actual situation and subsequent mold manufacturing related restrictions;

[0060] S3. Perform formability analysis:

[0061] Analyze the for...

Abstract

The invention provides a punching processing quality control method of a large-scale covering component, and relates to a manufacture method of parts of car. The punching processing quality control method comprises the steps as follows: S1, establishing a CAD (Computer Aided Design) model; S2, compensating or modifying the CDA model based on relevant technologies; S3, analyzing the forming property; S4, setting and manufacturing a die; S5, detecting the material of a part; S6, detecting a covering component online; S7, detecting the covering component offline; S8, converting into a three-dimensional model; and S9, comparing and modifying. With the adoption of the punching processing quality provided by the invention, the quality of a punching component can be simply and conveniently controlled, thus, the consistency of the detecting speed and the detecting precision can be achieved; moreover, the processing quality and the production efficiency of the covering component are improved; and the demand on detecting of large-scale complex covering component under mass production can be met.

Description

technical field [0001] The invention relates to a method for manufacturing auto parts, in particular to a quality control method for stamping processing of large covering parts. Background technique [0002] In the manufacturing process of automobiles, the manufacturing quality of covering parts has a great influence on the quality and cost of the whole vehicle. Advanced manufacturing technology and quality management level are also becoming more and more important. In the manufacturing process of large automobile panels, stamping processing plays a very important role. The processing errors generated in stamping processing will seriously affect the subsequent assembly and other links, resulting in a decline in the overall quality of mechanical products; and due to inability Timely discovery of existing errors will result in the scrapping of processed products, waste of parts and materials, increase in cost and greatly affect production efficiency. Therefore, the quality i...
