Abstract: |
Starting from the influencing factors of large diameter and thin-walled metal hydraulic tube bending, based on the process of analysis and experiment, the reasonable space of the bent core head and the hole of tube are found out, by technologic measures such as improving the bent core head structure. The bending method of large diameter and thin-walled metal hydraulic tube has been developed, so as to solve the problem of the tube is hard to bend into shape. |
