At present, the computer simulation of agricultural machine castings has achieved remarkable results, helping designers improve process design and improve the quality of castings. However, software simulation of solidification requires improved physical models. Computerized numerical calculation of solidification castings, composition In order to form the casting in three dimensions, the initial conditions and boundary conditions are determined, which meets the actual needs of casting production to a greater extent. Therefore, it is still necessary to study the design of the casting process to realize its function and potential practical experience.
On the other hand, agricultural machine castings production enterprises must strictly control the solidification simulation software during the production process, strengthen technical training, and accumulate experience in the use of solidification simulation software. This is required for the production of high-quality castings, and it is also the The successful application, the selection of the process plan and the process parameters of the cylinder block, and the issues that must be considered in the process design, in order to solve the problem of the air hole structure and design of the exhaust system.
In order to solve the problem of software simulation, users who meet the needs can use different standards to analyze the formation of casting shrinkage from different angles. Users can easily choose according to their needs, and can quantitatively analyze the formation of casting defects in various ways. The actual casting analysis shows that the method works well. With the rapid development of the automotive industry and the aerospace industry, casting defect testing and quality assessment have become a very important part of industrial production.
In terms of casting defect detection methods and related technologies, many achievements have been made so far. Therefore, the application of assessing the quality of castings is briefly reviewed, and the shrinkage defects of the alloy base casting factory are evaluated and analyzed. Under the conditions of die casting and filling, Surface cracks and internal cracks are caused by solidified layered filling and shrinkage. Due to different punctuality, the shrinkage of the shaft means the feed characteristics and maintenance time of different casting wall thicknesses. The idea of preventing and eliminating the defects of magnesium alloy die castings is proposed. Measures.
