Abstract

PURPOSE: To obtain a laminate, e.g. an iron core, without using rivets, by joining laminated members, which are blanked with a die and a punch, with pull-ups formed by squeezing the members through protruded hooks.
CONSTITUTION: Several sheets of members 3a are blanked from the material 11 with the die 8 and punch 5; the member 36 having the semicircular cuts 7, with the die 8 and the punches 5 and 6. The first member 3a is caught by the protruded hooks 10b of the pull-up forming member 10, and the other members 3a are laminated one by one in the opening 8a to the height A of the die 8. Said first member 3a is then squeezed with the protruded hooks 10b under the pressure of blanking to form the pull-ups 4 on its edges. The members 3a are pressed into the opening 10a one after another and joined with the pull-ups 4. Finally, the member 3b having the semicircular cuts 7 free from pull-ups is pressed into the opening 10a and integrated with the members 3a, thus giving a laminate.
