Description

Casting tool for ultra-long CS coil Technical Field The utility model relates to the technical field of coil casting, in particular to a casting tool for an ultra-long CS coil. Background In the manufacturing process of a nuclear fusion device, a CS coil is used as a key component, and the quality and performance of the CS coil directly influence the overall operation effect of the device. The CS coil concerned this time has unique dimensions up to 3.1 meters in length after casting, 0.45 meters in outside diameter, 0.32 meters in inside diameter, 6.5 cm in wall thickness, a significant increase in length compared to conventional coils, and a wall thickness that results in a relatively narrow interior space. When the existing coil casting tool is used for coping with the ultra-long CS coil, a plurality of problems to be solved are exposed. Firstly, because the length of the CS coil after casting is longer, the existing tool demolding mode faces a great challenge. Common demolding methods, such as demolding purely by manpower or simple mechanical assistance, are difficult to operate and are extremely prone to damage to coils when faced with such extremely long coils.
