Abstract
PURPOSE: To improve the yield of material without any need for providing feed bridge and bridge to a strip material by beforehand blanking scrap parts from the strip material then cutting the connecting parts between the blank materials and the strip material.
CONSTITUTION: A strip material 1 is supplied from a coil, exists between the pad 2 and lifter 3 of an extracting device 18 and moves intermittently by the length of the radius of a blank material B to the A direction. After the strip material 1 has moved by the length of the radius, it stops and scrap parts S1, S2 are set between a punch 11-1 and die 11-2. An upper die base 4 and a lower die base 5 are approached to blank the scrap parts S1, S2 with the punch 11-1, die 11-2, etc. At the same time, the coupling part of the blank material B1 is cut with cutting blades 15, 16. When the extracting device 18 exists above in the C direction, the scrap parts S1', S2' are extracted by punch and die 13, 14.
