Abstract

PURPOSE:To improve the yield of products by incorporating the caulking die at the cutting blade of the upper die, arranging the caulking punch at the position corresponding to the above caulking die in the lower die holder, and arranging the sensor to detect the parts-pitch of the products. CONSTITUTION:Because the caulking die 10 is incorporated in the cutting blade 1 of the upper die on the punching die and also the caulking punch 13 is arranged in the lower die holder, so the caulking to caulk the cut part to the sheet material 15, etc., following after cutting the part on the time of cutting the part 20 from the base material 8 with the punching die can be executed together with the cutting. Further, the parts-pith after caulking is detected with the sensor 18 to detect the parts-pitch, if the parts-pitch is out of the prescribed value, the pressing machine is stopped and the defective products is removed. Therefore, the productivity of the pressing work is improved and the yield of products can be improved because the products having the large error of parts-pitch can be selected and removed.
