Analysis of pipe punching process and mold optimization design
Abstract: Taking the bracket part made of hollow pipe as an example, the structural characteristics of the part are introduced, and the punching process of the bracket part is analyzed. By establishing a mathematical model, the correlation between the punching size and the diameter of the pipe and other relevant sizes is analyzed, and the influencing factors of the strength of the hollow pipe after punching are analyzed, so as to realize the optimization design of the products in the application of hollow pipes.
Key words: hollow pipe; punched hole; process analysis; optimization
