Detailed Description

Referring to fig. 1 to 4, a specific structure of a preferred embodiment of the present invention is shown, which is a stamping jig for a shaft cover of a printer, including a substrate 10, a stamping module 20 and a cylinder 30.

In this embodiment, the substrate 10 is provided with a cavity 11, and the substrate 10 is provided with a stopper 12 at a side edge of the cavity 11. The punching module 20 is arranged in the cavity 11, and an installation space 40 for installing a rotary shaft cover of the printer is formed between the punching module 20 and the cavity 11. The base plate 10 is provided with a through hole 13 penetrating through the center of the cavity 11, the cylinder 30 is assembled at the bottom of the base plate 10, and the driving rod of the cylinder 30 extends upwards to the cavity 11 through the through hole 13.

The stamping module 20 mainly comprises a limiting part 21 and a plurality of stamping blocks 22, and stamping knives 220 are arranged on the outer side surfaces of the stamping blocks; the limiting piece 21 is concavely provided with concave positions 211 corresponding to the number of the punching blocks 22, and the punching blocks 22 are assembled in the concave positions 211; the plurality of press blocks 22 are movably connected to the driving rod of the cylinder 30 in the concave portion 211. Specifically, a lower pressing block 31 is mounted at the end of the driving rod, a tapered surface 311 is arranged at the bottom of the lower pressing block 31, and each punching block 22 has an inclined surface 221 which can be attached to the tapered surface 311; briquetting 31 pushes down can once only drive the polylith and the punching press piece 22 that briquetting 31 links to each other removes, of course, in order to make punching press piece 22 can realize the reset function, can be at the haulage rope that sets up between actuating lever and each punching press piece 22, can realize resetting punching press piece 22 toward pulling back when actuating lever rebound.
