[Operation of terminal crimping machine]
Next, the operation of the terminal crimping machine according to this embodiment will be described.

  FIGS. 8A to 8C and FIGS. 9A to 9C show the operation of the feeding mechanism in the process (one cycle) from the terminal feeding process to the crimping. In the drawing, only the core wire crimping portion 1d is shown as the portion to which the terminal 1b is crimped, but the coated crimping portion 1g is also crimped simultaneously.

  FIG. 8A shows an initial state before the terminal 1 b is sent between the anvil 30 and the crimper 32. The roller 19 is on the high cam surface 181H of the cam plate. The terminal feed base 6 urged upward around the shaft 601 by the compression spring 49 is held in a horizontal state. The feed claw 35 is engaged with a feed hole 1 h of the chain 1 a on the terminal feed base 6 by a tension spring 56.

  FIG. 8B shows a state where the terminal 1 b is being sent between the anvil 30 and the crimper 32. The feed arm 7 is moved in the terminal feed direction (right direction in the figure) by driving the fluid pressure cylinder 36 (FIG. 5). The roller 19 is moved from the high cam surface 181H of the cam plate to the low cam surface 181L. Thereby, the terminal feed base 6 is rotated counterclockwise around the shaft 601 by the compression spring 49, and one terminal 1 b is lifted above the upper end of the anvil 30. Further, the feeding claw 35 is also moved in the terminal feeding direction at the same time, the chain 1a is advanced toward the anvil side, and the terminal 1b connected thereto is sent above the anvil 30.

  FIG. 8C shows a state in which the terminal 1 b is sent between the anvil 30 and the crimper 32. By further movement of the feed arm 7 in the terminal feed direction (right direction in the figure), the roller 19 moves on the lower cam surface 181L while maintaining the inclined state of the terminal feed base 6, and at the same time, the feed claw 35 is also moved. The terminal 1b (core wire crimping portion 1d) moves in the terminal feed direction and is sent between the anvil 30 and the crimper 32 and above the anvil 30. FIG. 10 is a perspective view at this time.

  In this terminal feeding process, since the terminal 1b is fed with the end of the terminal feed base 6 raised above the upper end of the anvil 30, the terminal 1b has its side plate 1f or the like caught on the anvil. Instead, it is sent between the anvil 30 and the crimper 32.

  FIG. 9A shows a terminal feed completion state in which the terminal 1b (core wire crimping portion ld) is placed on the upper end (crimping tooth) of the anvil 30. FIG. After the terminal 1b is sent between the anvil 30 and the crimper 32, the feed arm 7 is retracted and returned to the original position (initial state) by the reverse drive of the fluid pressure cylinder 36 (FIG. 5). At this time, the roller 19 moves backward from the lower cam surface 181L of the cam plate to the original position on the higher cam surface 181H, and the terminal feed base 6 rotates clockwise in the figure against the urging force of the compression spring 49. Is returned to the horizontal state. At the same time, the terminal 1 b (core wire crimping portion 1 d) between the anvil 30 and the crimper 32 is placed on the upper end of the anvil 30. Further, the feed claw 35 comes off the feed hole 1h of the chain band 1a against the urging force of the tension spring 56, rides on the chain band 1a, returns to the original position, and is engaged with the next feed hole 1h. The

  9B and 9C show the terminal crimping process. After the electric wire is supplied by an electric wire supply mechanism (not shown) and the core wire is placed on the contact 1c (core wire crimping portion 1d) (not shown), the press machine is driven to lower the crimper 32 and the terminal on the anvil 30 Crimp to 1b. At the same time, the connecting portion between the chain 1a and the terminal 1b is cut by the movable cutter 14 and the cutter block 17 (shown in FIG. 3) to separate the terminal 1b. After crimping the terminal, the press machine is driven in the reverse direction to move the crimper 32 back to the original position.

  As described above, the feed mechanism in the terminal crimping machine of the present invention can simultaneously feed the terminal 1b and swing the terminal feed base 6 by one reciprocating motion of the feed arm 7.

  Although the present invention has been described with reference to several embodiments, it goes without saying that the present invention can be variously modified without departing from the gist thereof.
