Chain buffering device of stamping machine

The utility model relates to a chain buffering device of a stamping machine, which comprises a pneumatic clutch and an air delivery pipe, wherein an air inlet of the pneumatic clutch is connected with an air inlet pipe via an air inlet connector; the air inlet pipe is connected with the air delivery pipe via a reducer union; the diameter of the air inlet pipe is less than that of the air delivery pipe; the side face of one side, opposite to the air inlet, of the pneumatic clutch is connected with a power shaft of the stamping machine; the air delivery pipe is 12mm in diameter; the air inlet pipe is 10mm in diameter. The side face of one side, opposite to the air inlet, of the pneumatic clutch is connected with the power shaft of the stamping machine via a spline. The buffering device is additionally mounted on the chain, the shutdown speed of the stamping machine is reduced, the registration accuracy is improved, so that the stamping accuracy is improved, the printed product quality is improved, a defect rate of printed products is reduced, the production cost is lowered, and the production efficiency is improved.
