Research on Sizing Process of Large-sized and High Precision Aluminum Alloy Welding Shells
Focused on the features of the technical requirements of materials,properties,and dimensional accuracy for the large-sized and high-precision aluminum alloy welded shells,a comprehensive analysis and comparison of various current sizing process methods were conducted,and a thermal expansion sizing process plan was proposed based on equipment con-ditions of existing production process.The theoretical analysis of this process plan was conducted by using the theory of e-lastic-plastic mechanics.On this basis,the sizing process parameters and mold structure were determined through process experiments.After experimental verification,the data met the technical requirements of the product.
