Description

Technical Field

[0001] This invention belongs to the field of arc wire additive manufacturing, and specifically relates to an arc wire additive manufacturing method for complex metal components with protruding parts. Background Technology

[0002] Arc-wire additive manufacturing technology uses an electric arc heat source to continuously melt metal wire. Based on a designed 3D model, it gradually melts and deposits metal parts in a line-surface-volume sequence. The entire process can be controlled by a pre-programmed sequence, resulting in a high degree of automation. Due to its near-net-shape characteristics, arc-wire additive manufacturing technology offers high deposition efficiency, high wire utilization, fewer limitations on part size, and ease of part repair, making it suitable for in-situ composite manufacturing and the forming of large-sized components.

[0003] Since arc filament additive manufacturing technology constructs three-dimensional solid components by layer-by-layer accumulation, the path planning and design of arc additive manufacturing mostly adopts the horizontal slicing method. In practice, this method has revealed several shortcomings, namely: (1) horizontal slicing makes it impossible to directly prepare local protruding parts of the component, requiring a positioner for secondary preparation; (2) horizontal slicing leads to discontinuity in the additive manufacturing process; and (3) secondary preparation of protruding parts of the component results in inconsistent overall performance. Therefore, providing an arc filament additive manufacturing method for complex metal components with protruding parts helps to solve the efficiency problem of component preparation and improve the consistency of overall component performance. Summary of the Invention

[0004] The technical problem this invention aims to solve is to address the shortcomings of the prior art by providing an arc-fuse additive manufacturing method for complex metal components with protruding parts. This method, through 3D modeling optimization combined with path optimization and real-time adjustment of additive manufacturing process parameters, achieves one-time additive manufacturing of complex metal components with protruding parts. This ensures the continuity of the additive manufacturing process, improves the consistency of the overall performance of the complex metal components, and solves the problem of inconsistent and discontinuous structure and performance of complex metal components caused by secondary fabrication of protruding parts in the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: an additive manufacturing method for arc-fused wire for complex metal components with protruding parts, characterized in that the protruding parts and the complex metal component are integrally formed by one-time additive manufacturing, and the specific process includes the following steps: Step 1: 3D Modeling Optimization Step 101: Analyze the three-dimensional model of the complex metal component to determine the direction of arc fuse additive manufacturing; Step 102: Locally process the arc fuse additive manufacturing parts in the 3D model of the complex metal component that are not easy to implement, so as to ensure that they can be manufactured by arc fuse additive manufacturing. Step 103: Make the various rounded corners of the complex metal component's 3D model right-angled or beveled to reduce the difficulty of slicing and arc-wire additive manufacturing. Step 104: Support the bottom of the protruding parts of the three-dimensional model of the complex metal component and form an angle to ensure that it can be gradually manufactured by electric arc wire additive manufacturing. Step 105: Based on the requirements of different metals and components, supplement the machining allowance for each face of the three-dimensional model of the complex metal component; Step 2: Slicing and Optimization Step 201: Based on the analysis results in Step 101 and the direction of arc fuse additive manufacturing, slice the three-dimensional model of the complex metal component optimized in Step 1, and determine the slicing direction as horizontal. Step 202: Combine and slice the protruding part with the complex metal component as a whole, so that the protruding part can be manufactured together by arc fuse additive manufacturing, and obtain the arc fuse additive manufacturing path. Step 203: Calibrate the arc fuse additive manufacturing path and optimize any ambiguous paths to obtain the optimized arc fuse additive manufacturing path. Step 3: Arc-fused-wire additive manufacturing Step 301: Based on the optimized arc fuse additive manufacturing path obtained in Step 2, perform arc fuse additive manufacturing of complex metal components, and periodically measure the height formed by additive manufacturing to modify process parameters in a timely manner to ensure the height and position of protruding parts. Step 302: Complete the arc-fused wire additive manufacturing process to obtain a complex metal component with protruding parts.

[0006] The above-mentioned method for additive manufacturing of complex metal components with protruding parts using arc-fused wire is characterized in that the protruding parts of the complex metal components are derived from bevels, bosses, and mounting lugs.

[0007] The above-mentioned method for additive manufacturing of complex metal components with protruding parts using arc-fused wire is characterized in that the connecting portion between the protruding parts is integrally additively manufactured in one step.

[0008] The above-mentioned method for additive manufacturing of complex metal components with protruding parts using electric arc wire is characterized in that the complex metal component is a magnesium alloy, aluminum alloy, stainless steel, copper alloy, or nickel alloy component.

[0009] The above-mentioned method for additive manufacturing of complex metal components with protruding parts using electric arc wire is characterized in that the angle of the support treatment in step 104 is a 10°~30° angle.

[0010] The above-mentioned method for additive manufacturing of complex metal components with protruding parts using electric arc wire is characterized in that, in step 105, each surface of the three-dimensional model of the complex metal component includes a base surface and other planes and curved surfaces, and the machining allowance is 3mm to 8mm.

[0011] The above-described method for arc-fuse additive manufacturing of complex metal components with protruding parts is characterized in that the ambiguous path in step 203 refers to an unreasonable path or a path that cannot be implemented by arc-fuse additive manufacturing. Due to differences in path planning software, some paths may be incomplete or repetitive. Therefore, by calibrating the arc-fuse additive manufacturing path and optimizing the ambiguous paths, an optimized arc-fuse additive manufacturing path is obtained, avoiding additive manufacturing errors or interruptions in the additive manufacturing process.

[0012] The above-described method for additive manufacturing of complex metal components with protruding parts using arc-fused wire is characterized in that, in step 301, when the actual measured height of the additively manufactured layer differs from the design value by more than 1.5mm to 5mm, the slicing parameters are readjusted before continuing the arc-fused wire additive manufacturing process. Specifically, when the actual measured height is greater than the design value, it indicates that the actual layer height of the additive manufacturing is relatively high, therefore the layer height in the slicing parameters needs to be appropriately increased by a corresponding value; when the actual measured height is less than the design value, it indicates that the actual layer height of the additive manufacturing is relatively low, therefore the layer height in the slicing parameters needs to be appropriately decreased by a corresponding value.

[0013] Compared with the prior art, the present invention has the following advantages: 1. This invention first analyzes the three-dimensional model of a complex metal component. By locally processing the arc-fuse additive manufacturing parts that are difficult to achieve, such as filling concave and convex areas and holes, and rounding corners to make them right angles or bevels, combined with supporting the bottom of the boss, the additive manufacturing performance of the complex metal component is ensured. Then, through slicing and optimization of the obtained arc-fuse additive manufacturing path, combined with height timed measurement and process parameter adjustment of arc-fuse additive manufacturing, one-time additive manufacturing of complex metal components with protruding parts is realized, ensuring the continuity of the additive manufacturing process and improving the consistency of the overall performance of the complex metal component.

[0014] 2. The manufacturing method of the present invention is simple and controllable, ensuring the consistency of structure and performance of complex metal components with protruding parts, improving the preparation efficiency, and can obtain complex metal components that meet the requirements of use after further fine processing.
