The present invention relates to a punching press mechanism. The present invention comprises a frame, a drive member, a power transmission member which the drive member drives, and a stamping die set in which the power transmission member drives a punching operation, wherein the power transmission member includes a power transmission shaft which the drive member drives and an eccentric structure connected to the power transmission shaft and leaning to one side corresponding to a center of the power transmission shaft, wherein a power transmission part associated with the stamping die set is in the eccentric structure, wherein the die set is installed in a guide member fixed corresponding to the frame to move back and forth in the guide direction of the guide member. The present invention uses a power transmission method with a structure in which up and down sides are connected to directly convert a circumferential motion trace of the power transmission shaft into a stroke of the stamping die set, thereby greatly increasing efficiency even without using a middle conversion unit. In addition, according to the present invention, product quality with more accuracy can be obtained since an error rate can be lowered by accurate punching. Accurate fine control of a stroke height can be achieved by controlling the stroke height of the stamping die using a fine control member. |
