Abstract
PURPOSE: To improve economy and strength by pressing and fitting a guide part having outside annular grooves to a fixing part of a hollow cylindrical shape having beforehand been made in a working punch a having a blade part, the guide part and the fixing part of a diameter larger than said guide part.
CONSTITUTION: A punch 1 for press working is formed of a rod part 11 having a blade part 2 and a guide part 3 and a fixing part 4 which is another part coupled to the end part of the part 11. Said part 11 has the maximum diameter in the guide part, has the blade part 2 in its end part, and is formed with annular grooves 12 near the other end. The part 4 has a shape of a hollow cylinder. With the part 4 held fitted into the annular grooves of the part 11, they are pressed and fitted by using a pressing tool, whereby the rod part 11 and the fixing part 4 are coupled.
