Description

Technical Field

[0001] The invention relates to the field of moulds, in particular to a stator and rotor sector piece inlay mould structure for motors. Background Art

[0002] This type of stator and rotor sector punchings are mostly used in large generators such as large wind power, nuclear power, ships and warships. They are relatively large in size, with diameters ranging from as small as 1M to 7, 8M, or even larger. Due to their large size, overall mold processing can no longer be achieved, and the stator and rotor punching materials do not have the corresponding size to match them. Therefore, this type of punchings are divided into sectors according to the circle, inlaid piece by piece, and stacked layer by layer, and are named "sector-shaped sheets". This type of sector-shaped punchings requires very strict dimensional accuracy and burr size, so the mold manufacturing accuracy is also very high.

[0003] The existing motor stator and rotor fan-shaped piece inlay mold structure has certain disadvantages when in use. The original mold is an integral structure or a three-piece four-piece structure. This structure seems simple and easy to operate and maintain. In fact, the processing process is prone to deformation due to the large parts, the tooth profile indexing cannot be adjusted, the dimensional accuracy is difficult to guarantee, and the processing risk is high. This is one of the reasons. The second is that once the mold is damaged during use, the overall blade grinding is required, which reduces the service life of the mold. It is difficult to repair and maintain the mold when problems occur, and the later maintenance is more troublesome. The mold manufacturing and use have certain risks, which brings certain adverse effects to people's use process. For this reason, we propose a motor stator and rotor fan-shaped piece inlay mold structure. Summary of the invention
