Process device and method for magnetic pole shield coating solidification and molding

Abstract

The invention provides a process device and method for magnetic pole shield coating solidification and molding. The process device includes a first energy transfer system and a second energy transfersystem, wherein the first energy transfer system includes a first radial limiting support member, a first elastic cavity member, and a first fluid medium supply system; the first radial limiting support member faces a first surface of a magnet yoke and is disposed at a preset distance from poles to form a first accommodation space; the first elastic cavity member is a flexible sealed cavity and isdisposed on the first radial limiting support member and is located in the first accommodating space; and the first fluid medium supply system communicates with the first elastic cavity member and isused for supplying a pressurized fluid medium or a pressurized heating fluid medium to the first elastic cavity member. According to the technical scheme, the goal of unification of temperature risecontrol and unification of temperature distribution of the pole shield molding quality is achieved, the stress of the pole shield coating self-molding process is eliminated, the molding quality is ensured, and the peeling and breakage risks caused by the stress in the later use process are reduced.
