Example one

As shown in fig. 1-2, an i-shaped punch with a buffering mechanism comprises a base 1 and an i-shaped punch stem 2, wherein a buffering mechanism 3 is respectively arranged in two grooves of the punch stem 2, and each buffering mechanism 3 is in sliding connection with the base 1; the side wall of the base 1 is provided with a sliding groove 4 extending along the radial direction and more than one clamping groove 5 extending along the axial direction, and each clamping groove 5 penetrates through the base 1.

Specifically, each buffer mechanism 3 comprises a sliding rod 31 extending along the axial direction, a shaft shoulder 32 is arranged at the upper part of the sliding rod 31, a pressing block 33 is arranged at the lower end part of the sliding rod 31, and a spring 34 is sleeved on the sliding rod 31 between the pressing block 33 and the shaft shoulder 32; when the spring 34 is in a relaxed state, the lower end of the pressing piece 33 extends below the lower end of the ram 2.

Specifically, the base 1 is provided with two first holes 11 respectively adapted to a shaft shoulder 32.

Specifically, the slide rod 31 is integrally formed with the shoulder 32.

Specifically, the plunger 2 is integrally formed with the base 1.
