10MN hydraulic press pressure system design

Abstract: The name of this project is "10MN hydraulic press pressure system design," the main purpose of the hydraulic machine is large-scale Ship forging, the main function is to achieve the upper and lower dies move synchronously with the synchronous rotation, use this function to achieve with a mold, by means of hydraulic cylinders rotating the whole movement with the end of the mold, forging repeatedly, and then complete the purpose of processing a large plate. The graduation project is the design of the subject, so this paper written specification format. In this thesis, there are six important parts. The first part is written in the introduction to this topic, the significance of including background and design of this project, that of China's hydraulic industry level with the world advanced level there are still some deficiencies compared to the suppression of large panels of large hydraulic machine has been designed to further a bit less. The second part is the design of the hydraulic system, including the chamber pressure and flow depress the plunger cylinder and auxiliary piston in the cylinder under the fast-forwarding of workers, as well as the hydraulic circuit design, such as holding pressure balance loop circuit and the like. Standard parts such as various hydraulic components selection valve and relief valve selection. The third part is depress the plunger cylinder design, including calculation of important parameters, the design causes and important structures. The fourth part is the auxiliary piston-cylinder design and calculation, including the reasons and advantages of the design of some important structures. The fifth part is a rotary gear mechanism connected with the mold section, including checking their vital parts. The sixth part is a summary of the entire design, including the shortcomings of this design.
