Definitions

  • Fig. 14 and Fig. 15 are explanatory diagrams showing the operational process such that nut blank 11 finished with the piercing and pilot portion enlarging process shown in Fig. 2 of the Patent document 1 ( JPH 8 - 29392 ) is pushed out from die 31 and held by a pair of opposing fingers 39, 39 of the transfer mechanism reciprocating along the front of die 31. Both fingers 39, 39 are activated by a spring (not shown) in the direction of approaching each other, and the space between the two fingers is a little smaller than the opposite side dimension of nut blank 11.
