A high-precision stator punching sheet comprises a base and a punching die, wherein the base comprises a lower die base and a lower die base plate arranged on the bottom surface of the lower die base; the punching die is arranged over the lower die base and comprises a limiting device and a die body; an upper die base is installed above the limiting device and the die body; an upper die base plate is arranged between the upper die base and the die body; a stator shape splice block is arranged at the bottom of the upper die base plate; a stator punching sheet one-time forming composite die is adopted, the production working hours are decreased, compared with a traditional single groove type notching die, the production efficiency is doubled, and it only takes 3 seconds to punch one punching sheet; meanwhile, the manufacturing cost is remarkably reduced, and the product quality is obviously improved; and a special-shaped cutting tool is arranged between a punching female die and a punching male die, and punching can be conducted on special-shaped parts according to different requirements.
Description
technical field [0001] The invention belongs to the field of generator manufacture, and relates to a one-time forming compound die for stator punching with extremely high precision requirements, and is especially suitable for the production of stator punching with extremely high precision. Background technique [0002] The processing procedure of motor stator duplex stamping is an important procedure in motor manufacturing. At present, the commonly used compound mold is only formed on the groove structure, while other shapes and sizes are formed on the blanking die. However, when processing other shapes of the stator punching sheet with this mold structure, the efficiency is low due to multiple steps, which affects the production and processing progress, and it is difficult to guarantee the extremely high relative size and behavior tolerance. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a high-precision ...
