Abstract

PURPOSE: To improve core press-cutting accuracy and reduce work time by press- cutting the respective slots of a shaft hole, rotor, and stator with the first press-cutting machine and the internal and external surfaces of as the stator with second press-cutting machine and separating the rotor and the stator.
CONSTITUTION: The press-cutting machines 15 and 16 are arranged in parallel and the hoop material 8 passes through these machines. Firstly, the shaft hole 3, rotor slot 4, and stator slot 5 are press-cut using the press-cutting machine 15. Then, both the internal and external surfaces of the stator 2 are press-cut using the press- cutting machine 16. Both the rotor 1 and the stator 2 are separated and housed in the core accumulation cylinders 13 and 14. This improves the accuracy of concentricity. Since the press-cutting tailings are all of press-cutting down type, press- cutting speed can be increased.
