Embodiment 1

[0029] Using 316L stainless steel rod-shaped castings as blanks, the base structural parts are prepared by machining, and the base structural parts are subjected to a heat treatment process of 850 ° C ~ 985 ° C / 0.5 h ~ 2 h / oil cooling or air cooling. Then, the structure and composition of the matrix structural parts are determined through composition and structure detection. Then use high-precision three-dimensional scanning or three-coordinate machine to scan the matrix structure, and form the matrix structure model through data processing software such as GomInspect. Using Cero / ProE, UG or other 3D model design software, based on the matrix structure model, carry out the required complex structure design on it, and finally synthesize an integrated 3D model. Use Magics or other software to perform two-dimensional slicing processing on the three-dimensional model, that is, to divide the model data into a series of two-dimensional data along the Z-axis direction according t...

Abstract

The invention relates to a method for growing complicated structures on the surfaces of castings and forgings based on wire 3D printing. The method comprises the following steps: (a) basal body structural parts are prepared; (b) three-dimensional scanning or three-coordinate machine modeling is performed on the basal body structural parts to prepare basal body structural part models; (c) structural design is performed on the surfaces of the basal body structural part models to obtain final part three-dimensional models; (d) two-dimensional slicing is performed on the three-dimensional models;obtained parameters are leaded into a 3D printer; and wires with the same materials with the basal body structural parts are leaded in to prepare printing; and (e) the basal body structural parts areplaced in the 3D printer; and added material manufacturing is performed on the surfaces of the basal body structural parts. The method generates the complicated structures on the surfaces of originalbasal body structural parts through the 3D printer; and meanwhile, the wires and the basal body structural parts are the same in material, so that printed complicated parts and the basal body structural parts are in tight metallurgical bonding and connection, and thick structures and centralized stress of the castings and low utilization rate of the forgings caused by machining are prevented.

Description

technical field [0001] The invention relates to a method for growing complex structures on the surface of castings and forgings based on wire 3D printing, and belongs to the technical field of metal forming and manufacturing. Background technique [0002] At present, there are four commonly used methods for the industrial production of parts with complex shapes and structures: 1. Using precision casting to prepare complex precision castings; 2. Using forged blanks to remove materials through mechanical processing to obtain the final Parts; 3. By powder metallurgy, the powder is put into the mold and manufactured by high-temperature sintering; 4. Using additive manufacturing technology, it is processed by 3D printing platform. However, the above methods are not applicable to large parts and parts with complex structures on the inner wall or outside, and there are the following problems: 1. Precision castings will cause the parts to have coarse structures, stress concentration...
