At the beginning of 2017, with the active cooperation of the production department and the tooling group, the technical department successfully completed the corbel compression bushing tooling for Shenzhen Metro Line 7. In order to meet the verticality of the bushing 0.4 and the dimensional tolerance of 0.05, a mechanical jack was used as an auxiliary device, and the bush was placed in liquid nitrogen for cooling. Through the guiding action of the auxiliary components, and the jack as the positioning reference, the pillow was successfully completed. The pressing process of beams has been completed for 1 column, 12 corbels and 24 corbels. No unqualified parts have been produced, and an important technological breakthrough has been completed. This tooling is after the traction beam. For a breakthrough in important large components, our company has the ability to independently produce corbels
