Abstract
PURPOSE: To manufacture a laminate of firmly stuck matallic plates having high mechanical strength with high efficiency, by stucking plural metallic plates together through engaging means respectively formed on both sides of metallic plate.
CONSTITUTION: Metallic plate is pressed in the plate thickness direction with the 1st dies M (Ma and Mb). Namely, recessed part 3 is formed on the surface of metallic plate 1 with punch Pm and half-punched leg parts 6 and 6 are formed projecting from the reverse surface by receiving part Qm. Metallic plates 11, 12W1n after the 1st press process are layered on lower die Nb of the 2nd dies N (Na and Nb). Next, punch Pn of upper die Na is fitted in recess part 3 to project the bottom wall, and consequently leg parts 6 and 6 of metallic plates 12W1n are deformed outward plastically to form engaging leg parts 5 and 5. Further, engaged projections 4 and 4 to be engaged with leg parts 5 and 5 are formed with taper part Pt of punch Pn. Leg parts 6 and 6 of metallic plate 11 are unnecessary, so they are eliminated at a proper point in time.
