Description

Technical field

[0001] The invention relates to the technical field of manufacturing stator and rotor cores for motors used in new energy electric vehicles and precision motor stator cores that require high motor performance. Specifically, it relates to a stamping progressive die for motor stator and rotor cores that adopts dispensing lamination and Dispensing process. Background technique

[0002] The motor stator and rotor core includes the motor stator core and the motor rotor core, which are both made of silicon steel sheets (punched sheets). Silicon steel sheets are usually stamped on a punch machine using a stamping progressive die. Usually, the stamping progressive die is provided with an upper template, a lower template and a discharge plate located between the upper template and the lower template. A plurality of punches are installed on the upper template, and the corresponding position of the lower template is installed with the The die is matched with the punch...
