[

Then, the first double-blade cutter 32 cuts a portion of the strip-shaped metal disc W1 after the machining of the first punch 31 except for the connecting portion Wd to form a single- (See Fig. 1 (c)). At this time, the intermittent feed distance of the strip-shaped metal disc W1 is the cut-off interval of the first double-head cutter 32, and the width of the rolled-up metal plate W2 is set by the cut-off interval.

At this time, the ends of the first and second bending members 63 and 64 are in contact with the upper surface of the metal plate W2.

When the upper base 20 further descends in this state, the upper surface pressing member 62 is not further lowered and the metal plate W2 is fixed, as shown in FIG. 5C, and the first and second bending members 63 And 64 are further lowered along the side surface of the pin member 61 so that both sides of the metal plate W2 are bent at right angles. The divided bottom face 1c thus folded is located on the bottom face of the pin member 61 and abuts to form one bottom face 1c. However, since the length of the male engaging portion Wb is longer than the female engaging portion Wa So that the arm-and-male engagement portions Wa and Wb are not fully engaged.

At this time, the first and second side pressing members 65, 66 provided at the side of the pin member 61 are pressed by the respective pressing members 67, 68, which are lowered by the lowering of the upper base 20, (61) and comes close to the side surface of the pin member (61).

Then, when the rectangular tubular fixed terminal 1 is formed by the second bending die 60, the fixed terminal 1 is in tight contact with the pin member 61. 3A and 3B, when the pin member 61 is moved to the retracted position, the fixed terminal 1 is also moved together. In the moving process, the fixed terminal 1 moves to the backward movement line of the pin member 61, So that the fixed terminal 1 can be separated from the pin member 61. As a result,

Then, the fixed terminal 1 separated from the pin member 61 is conveyed to the evacuation conveyance line 80 by the conveyance mechanism 81. The feed mechanism 81 operates each time the pin member 61 moves backward and feeds the separated fixed terminal 1 to the discharge conveying line 80. The end of the discharge conveying line 80 is bent at a right angle, 1) is limited.

6, the tap processing machine 82 provided in the discharge transfer line 80 is moved to the position where the fixed terminal 1 transferred to the discharge transfer line 80 is stopped, And the fixing mechanism 83 is advanced to fix the fixed terminal 1, so that tapping by the tapping machine 82 is normally performed.

Subsequently, the fixed terminal 1 having been subjected to the tapping process is transferred to a portion bent at a right angle by a discharge mechanism (84) provided at the end of the discharge conveyance line 80 and discharged.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to be illustrative of the present invention and not to be construed as limiting the scope of the present invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
