1.On this basis, a kind of symmetry bevel automatic welding equipment with vertical and horizontal tracking system is designed, which has met the production requirement well.
2.The procedure is developed for optimal design of the eccentric compre-ssed solid belly,steel post and the lattice steel post in which eccentric pressureact on to solid axle that includes welding compose I-shaped cross-section withthe double axes of symmetry and the wings cut by blaze.
