Abstract

PURPOSE: To prevent the production of burrs and improve the accuracy of parts by half blanking the work with a punch of an outside shape larger than the blanking hole of a die then blanking the half blanked work with a die and a punch larger than the work shape.
CONSTITUTION: A metallic sheet material D is disposed between a female die B1 provided with a blanking hole 12 of the same shape as the outside shape of a part, and a knock-out 13 and a male die C1 provided with a punch 14 larger than the hole 12 and a stripper 15. Next, the punch 14 is lowered to half blank the material D, after which the punch 14 is moved upward, thereby separating the material D" by the operation of the knock-out 13. Thence, the material D" is inserted between a die 21 provided with a blanking hole 22 larger than the hole 12 of the die 11 and a punch 24 smaller than the hole 12, and the punch 24 is lowered, whereby the material is shorn to a part A and a slug D'''.
