The external dimension of the socket end is formed by a die, and the socket die is generally processed by numerical control during manufacturing, so that the precision is easy to control. When the bellmouth steel ring is manufactured, 4 steel plates with arc angles are welded into a complete steel ring in a common manufacturing process. At present, a bending machine is generally adopted for processing the arc angle of the steel plate, but due to the reasons of poor control of elasticity of the steel plate, strength of the bending machine and the like, the radius and the size deviation of the arc R angle after bending of the steel plate are large, so that the dimensional accuracy of the steel ring of the bellmouth of the component is insufficient, and the waterproof effect of the component is poor during installation.
