[0002] Spherical bearings are a kind of structural support device commonly used in bridges. They mainly transmit loads and reaction forces through spherical contact, thereby realizing the connection between the upper and lower structures of the bridge. They have the characteristics of strong bearing capacity, reliable force transmission, flexible rotation and good seismic performance. They can provide reliable support for the normal use and safe operation of bridges, and are suitable for various bridge projects such as large spans, curves and oblique intersections. The spherical bearing is mainly composed of bearing bottom basin, spherical wear-resistant plate, spherical crown lining plate, flat wear-resistant plate and upper bearing. Among them, a concave spherical surface is set on the bearing bottom basin, and the spherical wear-resistant plate is installed in the concave spherical surface to form a rotation sliding surface with the spherical surface of the spherical crown lining plate, thereby meeting the rotation requirements of the spherical bearing.

[0003] The spherical wear-resistant plate is a flat plate structure before assembly and needs to be pressed into a spherical shape so that it can be installed in the concave spherical surface of the support base. The existing spherical wear-resistant plate installation methods are mainly: (1) manual assembly, placing the spherical wear-resistant plate on the concave spherical surface of the support base, and using manual force to squeeze and deform the spherical wear-resistant plate and fit it to the concave spherical surface. This method has low installation efficiency and difficult to control assembly quality; (2) assembly using molding tooling. This method requires the manufacture of special tooling and molding equipment, has a long manufacturing cycle, and the cost of tooling and equipment is high; (3) freeze molding, molding and freeze molding the spherical wear-resistant plate. This method has better quality, but has high requirements for dimensional control, and has a long production cycle and high cost.

The bottom end of the auxiliary molding block 5 is a convex spherical surface, and the convex spherical surface is matched with the shape of the concave spherical surface 6. A tiny plane is provided at the center position of the bottom end of the auxiliary molding block 5. While not affecting the overall molding of the spherical wear-resistant plate 2, the auxiliary molding block 5 is ensured to be placed stably.
