Abstract

The invention discloses a mold structure for spinning forming of a multi-cell superconducting cavity and a moving-out method of the mold structure. The mold structure comprises a core rod and a core mold, the core rod is inserted in the core mold, and the shape of the core mold is matched with the internal structure of the superconducting cavity. The core mold is made of a low-melting-point material, and the low-melting-point material is taken out of a workpiece by heating after forming is completed, so that the problem of taking out the core mold after spinning is solved, the production of the multi-cell superconducting cavity by a spinning process is implemented, and one-step forming of the multi-cell superconducting cavity is realized.

Description

technical field [0001] The invention relates to the field of material forming, in particular to a mold structure for multi-cell superconducting cavity spinning and a removal method thereof. Background technique [0002] Superconducting accelerators are important equipment in scientific research and many scientific projects, and superconducting accelerating cavities are the key components of superconducting accelerators. Multicellular gyrotron superconducting cavities are the most demanding superconducting cavities. The current manufacturing method is A bowl-shaped part stamped into a half-cell, welded into a cell by two half-bowls, and then welded into multiple cells, such as figure 1 As shown, taking the 9-cell superconducting cavity as an example, 18 half-bowls need to be punched out, which are welded by electron beam welding with 18 welds after processing, that is, 18 times of punching, 18 times of precision machining, and 18 times of welding. There are many processes. ,...
