PUNCHING DEVICE AND MULTI-CHANNEL CAN LID PUNCHING SYSTEM

This application discloses a stamping device and a multi-lane shell stamping system, and the stamping device is used for simultaneous stamping of multiple shells, comprising a plurality of stamping die sets arranged in an array. Each stamping die set comprises an upper die and a lower die. The upper die is integrally formed, and the outer diameter of the upper die is larger than that of the lower die, and the bottom edge of the upper die forms a locating part for the curling of the shell to be processed. The present invention eliminates the movable locating cup, which can avoid the difficulty of mounting and dismounting the die due to the compact six-lane structure. At the same time, it adopts the method of directly increasing the diameter of the upper die, which not only avoids the mounting and dismounting of the locating cup, but also realizes the locating effect of the shell.
