Abstract

PROBLEM TO BE SOLVED: To prevent the generation of a shear drop, a broken surface, a burr or the like by pressurizing a metallic material with a pressurizing tool having the outside shape larger than the inside shape of a die, forcing a part of the metallic material into a die to form a thin wall part in the outer periphery of a forcing part and blanking the forcing part with a punch. SOLUTION: A plate shaped metallic material 1 is set on a die 2. The metallic material 1 is forced into the die 2 up to a half way in the wall thickness direction with a pressurizing tool 3 having the outside shape larger than the inside shape of the die 2 to form a forcing part 4, and also a thin wall part 5 is formed in its outer periphery. A blanking punch 6 having the outside shape smaller than the inner shape of the die 2 is lowered from the upper side of the forcing part 4 which is forced into the die 2 up to a half way to blank the forcing part 4. In such a case, since the forcing part 4 is separated from its peripheral thin wall part 5, it is surely blanked even with a weak pressure, and a shear drop, a broken surface, a burr or the like is hardly generated in the outer peripheral surface (separating surface) 12 of the blanked product 11.

2. Description of the Related Art Various metal products such as an electromagnetic clutch armature are usually punched, punched, or bent into a desired shape by press working. In normal press working, from the top of the metal material set on the die, a punch with a smaller outer diameter than the die is dropped and the metal material is punched into a desired outer shape, or a hole is made in a desired location of the metal material. I have. There are various methods for press working, and a special method is a precision shearing method such as a fine blanking method or a facing die shearing method. However, in either method, a metal material set on a die is punched out of a metal material by dropping a punch having a smaller outer diameter than the metal material, or a hole is formed. The principle is the same.

The separation surface of a product punched by the conventional general press working is hard to be smooth on the whole surface, and a part of the separation surface has a droop, a fractured surface, a burr, and the like.
When the metal material is thick, they are particularly likely to occur. According to the fine blanking method or the opposing die shearing method, there is an advantage that the dimensional accuracy of the separation surface is high (the size is easily obtained), but there are new problems such as an increase in the number of processing steps and burrs.
