The present invention relates to a punching device and, more specifically, to a punching device including a flexible multiline belt transfer device, capable of minimizing the transformation of a material, maintaining the precision of cutting, freely controlling a gap between a cutter and a feeder according to various lengths of the material, and preventing the material from sagging. To this end, the punching device includes: a press comprising upper and lower molds and a punching unit punching the material by moving the upper mold up and down; and a cutter cutting the material, punched by the press. The flexible multiline belt transfer device comprises: a pair of a flat belt main shaft and a sub-shaft including a feeder precisely transferring and supplying the material, punched at the rear of the press, to the cutter, and horizontally installed in the bottom of the feeder with a gap to be rotatable; and a flat belt wound in multiple lines to connect the main shaft and the sub-shaft with each other, and moving by touching the bottom of the material, transferred from the feeder to the cutter. |
