The machine is used for processing the end of the sew (non-seam) steel tube into abnormity of cup form and trumpet etc. Also it can be used in different shape of other tube of different materials. First, I established the solution of the topic through the comparation of the four kind method of different principles of expanding the end of the steel tube, according to the frondose producing condition. The solution is that I chose the method of pulling the shaft out of the principles in machine. The machine contains two enforce implements, controlled by the Hydraulic system, achieving the effect of clamping and expanding. Then I carried through the argumentation and draw-up the collectivity project of the machine, and designed the structure of the machine. Second, I designed the Hydraulic system of the machine. At the beginning, I calculated the perform part’s load of the external, and calculated the related parameter of the perform part and chose the suited type, then I chose the type of electromotor and pump, and chose the control valve and assistant component in the Hydraulic system, After plotted the principle diagram of the Hydraulic system of the machine, I transformed the diagram into the picture of the loop of the integrating blocks. And designed the structure of the integrating blocks according to the picture. Finally I designed the combination of the hydraulic pump and oil box. After disposed the pipelines, I assembled the integrating blocks and the combination of the hydraulic pump, also and the oil box, that is I designed the combination of the hydraulic system. Key Words The end of the steel tube molding The design of the machine The integrating blocks The design of the oil box Dispose the pipelines
