the blanking device is characterized in that a blanking groove is formed in the lower die, teeth are arranged on the inner wall of the periphery of the blanking groove, and a third spring is connected to the bottom of the blanking groove.

Further, still include the punching press head, the ladder groove has been seted up in the punching press head, the ladder inslot is equipped with trapezoidal pole, the one end fixed connection of trapezoidal pole be in go up the top of mould, be located the punching press head with go up between the mould be equipped with first spring on the trapezoidal pole.

Furthermore, a positioning rod is fixedly arranged at the bottom of the stamping head and penetrates through the upper die, a positioning hole is formed in the lower die, and the positioning rod is matched with the positioning hole.

Further, an insert is fixedly arranged at the bottom of the upper die.

Further, still include the cylinder, the output power of cylinder is connected in the top of punching press head.

Compared with the prior art, the utility model, its beneficial effect is:

the second spring and the buffer rod (the elastic cushion is arranged below the buffer rod) are arranged to play a role in reducing noise, the direct rigid contact between a traditional upper die and a traditional lower die is broken, so that noise is generated, the height of the buffer rod is lower than that of the blind hole, so that stamping can be normally carried out, after a blank enters the blanking groove, reciprocating motion in the blanking groove is realized under the action of the third spring, and the purpose of removing burrs in the blanking groove is realized due to the fact that the teeth are arranged on the periphery of the blanking groove and the finished product which does reciprocating motion is formed;

in summary, the stamping device for the hardware fittings can achieve the purposes of reducing noise and eliminating burrs.
