Background
The conical end socket is an end socket with a conical surface on the surface of the shell. It features that the speed of medium can be changed uniformly when it passes through it, so facilitating the discharge of viscous liquid and solid particles, but its mechanical property is poor and the discontinuous stress generated by shape jump at the joint of cylinder or connecting tube is large. In order to reduce discontinuous stress, a large end or a small end of the conical shell can adopt a flanging structure or a local thickening structure with arc transition. The design specification of the pressure container in China requires: when the half cone angle is larger than 30 degrees, the big end of the cone shell adopts a folded edge structure; when the half cone angle is larger than 45 degrees, the small end of the cone shell is of a folded edge structure, and the conical end socket is inconvenient to manufacture due to the fact that the wall thickness of the conical end socket is large and is adopted only when the process needs.
The existing conical end socket is directly stamped through a die in the stamping process, and creases easily appear in the stamping process, so that the production efficiency and the quality of the conical end socket are influenced.
