Research On The Precision Spinning Technology Of Curve Bus-type Aluminum Alloy Cylinder

Curve bus-type aluminum alloy cylinder is a more complicated parts of the rotary body parts, using welding methods processing volumes, labor intensive, forming poor accuracy, but also reduce the weld strength, weaknesses, such as stress concentration. Spinning method can be used seamlessly turn a whole body parts, but the spinning is elasto-plastic deformation, while the forming limit by factors such as material constraints, bus-type aluminum alloy parts Curve generally require multi-pass spinning, spinning a variety of combination, and in this article need to solve two problems: first, large-scale bus-based alloy parts Curve issue of forming a smooth, not cracks, folds, such as the accumulation of defects in materials; Second, the issue of forming precision parts precision of the size and shape required to meet the requirements. This article from the spinning processing theory and the reality of large aluminum alloy components forming Curve Bus Program conducted a study on a bus-type song spinning composite parts of the program; study and implementation of a composite spinning, constant linear velocity control, Core module size adjustment method of forming a variety of precision, and spinning in a variety of emerging issues targeted solution. Curve achieve a large-scale bus-based alloy parts Spinning the overall precision to achieve the desired purpose of the study, parts of the song of the spinning-type bus technology has played a certain role in promoting the exploration and。...
