According to the relevant requirements of GB/T8564-2003 'mounting technical specification for hydroelectric generating sets', stator core laminations are required to abut against positioning ribs or leave radial gaps, and if the gaps exist, the left gaps are required to be uniform; in the iron core lamination process, at least 2 slot sample rods and slot wedge slot sample rods required by a manufacturer are uniformly distributed according to each punching sheet for positioning, and the shaping rods are used for shaping. The yoke laminations are typically positioned by yoke keys and pins. The magnetic yoke without a positioning structure can uniformly penetrate through more than 20% of permanent screws for positioning, and each punching sheet is not less than 3; in the lamination process, the clearance between the punching sheet and the excircle of the stud of the rotor support is uniform, and the front and back surfaces of the punching sheet are consistent; the lamination mode and the lamination height are in accordance with the design requirements. The traditional lamination method achieves the shaping purpose by controlling the clearance between the positioning ribs and the lamination through the positioning keys. The above method has the following problems: 1. the restraint to the towards piece in the lamination process is generally only in the keyway department of interior circle or excircle, lacks the restraint to towards piece tooth portion, because there is the deviation of allowing in location muscle or the installation of navigation key, this deviation often can enlarge a lot after transmitting towards piece tooth portion, leads to the lamination data to worsen, makes it difficult to satisfy design size control requirement. Therefore, the prior art has the problem of poor lamination shaping effect.
