| description | The utility model adds an automatic material ejection device on the basis of the prior die for punching an upper die and a lower die of a rivet, which comprises a material ejection mechanism positioned on the lower die and a spring connected therewith, and is characterized in that at least one link mechanism capable of being rotationally connected to a lower die fixed seat and a deflector rod in rotational connection with an upper die fixed seat are further included; a lug boss extending outwards is arranged on the edge of the upper end part of the link mechanism, and is used for the rising action of the upper die; the deflector rod is in direct contact with the lug boss; and an upper link driving the link mechanism moves upwards to drive the material ejection mechanism in tight contact with a lower link of the link mechanism to rise synchronously, so that the spring is compressed and the material ejection action is completed. The utility model adopting the structure achieves the automatic material ejection i |
