The invention discloses manufacturing equipment for a nozzle of a main steam super pipeline of nuclear power and a pulling and extrusion manufacturing process for the nozzle. The manufacturing equipment is characterized in that a die base is arranged on and connected with a portal frame on a workbench; an upper die, a lower die and a locking block are respectively arranged on and connected with the die base; an upper sliding platform is connected with a pushing support rod; the pushing support rod is provided with a drawing die, a fork plate and a pull rod; a lock nut connected and tightly locked with the pushing support rod is arranged at and connected with the bottom of the pull rod; the pushing support rod is connected with an extrusion pull rod and an extrusion die when the nozzle is extruded; the extrusion pull rod and the pushing support rod are connected with a lock nut, thereby forming the manufacturing equipment through assembly and connection; and the pulling and extrusion process comprises the steps of primary drawing, secondary drawing and once extrusion forming. The equipment and the manufacturing process are simple and practical, and are applicable to manufacture multiple types of nozzles for the main steam super pipe of the nuclear power.
Description
technical field [0001] The invention belongs to the technical field of nuclear power main steam super pipeline components and relates to nuclear power main steam super pipeline nozzle manufacturing equipment and a nozzle extrusion manufacturing process. Background technique [0002] With the increasing development of the nuclear power industry and the rapid advancement of science and technology, the technical requirements for the nuclear power main steam super pipeline components, especially the key components - the nuclear power main steam super pipeline nozzles are also getting higher and higher. In the known technology, the original nuclear power main steam super pipeline nozzle equipment and its nozzles are mainly welded nozzles, which have limited service life, low service life and unstable product quality due to weld seam defects and heat-affected zones. Contents of the invention [0003] In order to overcome the deficiencies of the prior art and solve the proble...
