The stamping die consists of a base, a lower module, a limit rod, a sleeve, a spring group, an upper module, a punch, and a punching hole. When using the stamping die to stamp the core silicon steel sheets of small transformers, the core silicon steel sheets are placed on the lower module on the base, and the upper module is pushed downward by the external cylinder, so that the sleeve slides on the limit rod, and the first spring is squeezed, so that the punch is punched onto the core silicon steel sheet, and the punched part of the core silicon steel sheet falls from the punching hole, thereby completing the stamping of the core silicon steel of the small transformer.

[0030] Working principle:

[0031] When using a stamping die to punch and manufacture the core silicon steel sheets of a small transformer, the core silicon steel sheets are placed on the lower module 4 on the base 1, and the upper module 6 is pushed downward by the external cylinder, so that the sleeve 7 slides on the limit rod 5, and the first spring 8 is squeezed, so that the punch 9 is punched onto the core silicon steel sheets, and the punched fertilizer of the core silicon steel sheets falls from the punch hole 10, thereby completing the stamping of the core silicon steel of the small transformer. When assembling the punch 9, the worker inserts the punch 9 into the upper module 6, connects the air pipe of the external air pump to the air nozzle 25, starts the air pump, and allows the gas to pass through the air cavity 24, so as to push the piston 26, thereby pushing the pin 22 in the square groove 21 into the upper module 6, thereby fixing the punch 9, and thus facilitating the assembly of the punch 9 as much as possible. At 9, the air pump is started to suction, thereby sucking out the gas in the air cavity 24, causing the piston 26 to move, thereby completely retracting the pin 22 into the square groove 21, and by setting the second spring 23, the piston 26 is squeezed, so that the auxiliary pin 22 is stuck in the upper module 6, and by setting the sliding surface 28, the auxiliary pin 22 is inserted into the upper module 6. By setting the cover 27, the air nozzle 25 is dust-proof. When the punch 9 is punching, the punching distance will not affect the air nozzle 25. When it is necessary to limit the punched silicon steel sheet, the silicon steel sheet is pushed so that the inclined surface 32 is required to contact, so that the third spring 34 on the silicon steel sheet pressing block 31 squeezes the pressing block 31, thereby squeezing and limiting, thereby limiting the punched silicon steel sheet, and by setting the circular rod 33, the pressing block 31 is limited in the sliding direction.
