Design and analysis of hydraulic cylinder of 60 tons copper drawing machine

Continuous extrusion of copper produced,drawing through drawing machine,To harden and to achieve the purpose of improving surface quality.Hydraulic cylinder is an important part of the drawing machine,providing the impetus for the drawing.However,this hydraulic cylinder diameter ratio greater than 40,Therefore,the deflection due to weight of the hydraulic cylinder will impact on the work.Traditional design long-stroke hydraulic cylinder hydraulic cylinder general reference design manual.Aspect ratio of the hydraulic cylinder is less than 40 viable.But for the hydraulic cylinder aspect ratio greater than 40 do not apply.In this paper,the linkage equation of 60-ton hydraulic drawing,the hydraulic cylinder design and analysis to meet the job requirements.This approach not only applies to 60-ton hydraulic cylinder,also apply to other tonnage,long-stroke hydraulic cylinder.
