Rapid manufacturing method of clay model

Abstract

The invention provides a rapid manufacturing method of a clay model. According to the main technical characteristics, firstly, according to an appearance modeling effect picture, 1:1 three-dimensional modeling design is carried out, a three-dimensional model picture meeting the requirements of a user is drawn, then biasing is carried out on three-dimensional data external surface sizes, clay coating allowance is reserved, a basic frame of the clay model is designed, and segmentation is carried out according to appearance three-dimensional data of a cab so as to form machining foam body units; and then blocking machining is carried out on a cab model by adopting a foam machining center device, a cab appearance foam model is obtained by means of splicing, a clay positioning block is arranged according to set coordinates, positioning sizes are detected, a color different from the color of clay itself is coated on the clay positioning block, the clay is coated to the height of the colored surface of the clay positioning block, and the surface smoothing property is improved according to the three-dimensional data and the effect picture until the clay model is completed. By adopting the method, the efficiency for manufacturing the automobile cab clay model is substantially improved, the manufacturing difficulty of the clay model is lowered, the manufacturing cost is reduced, the product design period is shortened, and the method has certain popularization and application value.

Description

technical field [0001] The invention relates to a rapid production method of a sludge model, which is applicable to the production of various types of sludge models of automobile cabs. Background technique [0002] The clay model is a car body model that is sculpted with clay in traditional body design. Early car body models mostly used gypsum and wood boards as materials. Wooden models are characterized by small deformation, not easy to break, and can be stored for a long time. Gypsum is less expensive, but it is weaker and not as easy to modify repeatedly. [0003] At present, clay models are widely used in the design process of automobile products at home and abroad to confirm the final shape, mainly using machine tool processing and other proportional models or manual carving 1:1 clay models. These methods mainly have the following disadvantages: [0004] 1. The proportional model can only be used as a reference in the design stage, especially the arc surface and smal...

AI Technical Summary

Problems solved by technology

[0004] 1. The proportional model can only be used as a reference in the design stage of the project, especially the arc surface and small corners are difficult to process to achieve the expected effect, and cannot be used as the basis for the final determination of the shape, nor can reverse design

[0005] 2. The production cycle of pure manual 1:1 clay model is long

It takes a lot of time, manpower and material resources to make a 1:1 clay model and take samples to draw the main drawing board, and mainly rely on the human eye to judge the smoothness of the shape and connection. The reliability of the initial design is quite low, and the final produced Clay models may lose their value in comparison with 3D data

[0006] 3. The 1:1 milling of the overall model directly with oil mud can only be completed on a five-axis machine tool, but large-scale products such as heavy trucks and buses cannot complete the overall milling, and the processing cost is expensive, so it is not suitable for general deformed products
