Abstract
This paper introduces the structure and processing method of the main valve body of a type of rail-way freight car air distributor valve,briefly introduces the use of the distributor valve,analyzes the structure and key control points of the main valve body,combines the characteristics of product structure and material pro-cessing characteristics,sorts out the processing difficulties of the valve body,and formulates the processing process plan of the main valve body according to the existing processing equipment and experience.Using numer-ical control four-axis machining means,process positioning and special tooling and other solutions,the process-ing of the main valve body of this type of air distributor valve is effectively completed,and the processing quality is ensured,which provides a successful reference case for the processing of aluminum alloy valve body with simi-lar complex space pore structure and high precision requirements in numerical control machine tools.
