Abstract

PURPOSE: To eliminate the waste of hoop materials and improve material yield by separating between the parts and elongating the edge parts of the parts without blanking the gaps between the respective parts produced of a hoop material.
CONSTITUTION: After a hoop material 1 is subjected to square punching, and presing of side cut parts 2, it is subjected to punching of pilot holes 3 and elongating grooves 4, square holes 5 and separating parts 7 for forming interpart gaps are continuously pressed between the pilot holes 3. Then, the grooves 4 are elongated in the parts advancing direction in an elongating process, whereby the edge bent parts 6 for interpart gaps are elongated, and gaps 9 are formed between the members 8 that become the parts by way of square hole 4', square slit 5' and edge bent part 6'. The width A of these gaps 9 is, for example, about 1mm. According to this method, the blanking of the unnecessary parts of the parts is minimized. Since the bent parts 6' are used for post processes (processing such as plating), the hoop material 1 is effectively utilized.
