03 was supported by the reinforcing block 121. For this reason, the strength of the wiring mold 16 is reinforced by the reinforcing block 121, and when performing the cutting press on the covered electric wire 62 supported by the wiring mold 16, the cutting press process is performed in a stable state. Will be able to do.

(9) In the present embodiment, when performing the (cutting) pressing step, the coated block 62 is pressed by the pressing block 110. Therefore, the insulated wire 62
With the pressing force of the pressing block 110 against the wire, the wire habit such as the habit and twist of the insulated wire 62 can be removed. Then, in a state where the wire habit of the covered electric wire 62 is removed, the covered electric wire 62 can be sandwiched between the breaking projection 23 and the support convex portion 24 of the wiring mold 16.

(10) In the present embodiment, when a cutting (pressing) step is performed, a plurality (10 in this embodiment)
Cutting blades 108 and a plurality (10 in this embodiment).
Unnecessary portions of the covered electric wire 62 can be cut at the same time by the engagement with the cutting lower blade 124. In this case, since the portion near the unnecessary portion of the covered electric wire 62 is sandwiched by the support protrusions 24, it does not rise or shift during cutting, and the unnecessary portion of the covered electric wire 62 is securely and stably maintained. Can be cut. In addition, even after the insulated wire 62 is cut, the insulated wire 62 can be sandwiched between the breaking projections 23 and the support protrusions 24 of the wiring mold 16, and its stable state can be maintained.

(11) In the present embodiment, when the cutting press step is performed, unnecessary portions of the covered electric wire 62 are cut to generate cutting chips 122, and at the same time, the discharge holes 125 of the reinforcing block 121 and the moving block 120 are formed. , 123, the cutting waste 122 of the insulated wire 62 can be discharged.

By moving 72 in the transport direction, the transport table 173
Is also moved in the transport direction via the guide rail 170,
The work 181 of the accommodation table 178 was transported to a transport position where the pressing process was performed. In this case, when the follower roller 194 of the cam follower 190 is separated from the cam 188, the two support rollers 195 press while contacting the two surfaces of the work 181 with the urging force of the spring 193.
For this reason, the work 181 in the temporarily positioned state can be supported in a state where it is positioned by the respective support rollers 195, and the work 181 can be positioned in the positioning block 180.
It can be securely accommodated and fixed at a predetermined position between them. Accordingly, it is possible to prevent the work 181 from being displaced with respect to the accommodation table 178, and to maintain a state in which the press-contact pressing process can be normally performed.

(13) In the present embodiment, the support pillar 17
5 is pushed upward by the pushing part 166,
Workpiece 181 on storage table 178 transported to the transport position
At a predetermined height, and the position of the work 181 corresponds to the position of the wiring mold 16. For this reason, the work 181 is pressed from below onto the wiring mold 16 fixed to the turntable 13 and subjected to the press contact step.
Can be easily adjusted to be at a predetermined position, and the press-contact pressing step can be performed normally.

(14) In the present embodiment, in the press-contact press step, the covered electric wire 62 which has been subjected to the wiring step and the cutting press step is pressed from above the wiring die 16 by the press-contact portion 157 to cover the wire. The electric wire 62 was moved from the wiring mold 16 to the work 181 below. In this case, the wiring pattern of the insulated wire 62 sandwiched between the wiring molds 16 can be transferred to a predetermined position of the work 181 in the same state, and the wire support portion 184 and the pressure contact piece 187 of the work 181 can be moved. The five covered electric wires 62 can be wired while being pressed against each other. Therefore, by moving the covered electric wire 62 from the wiring mold 16 to the work 181 below, the wire support portion 184 and the press contact piece 18 of the work 181 are transferred.
7, the position of the insulated wire 62 can be easily adjusted, and the workability can be improved.

(15) In the present embodiment, the pressing portion 15
7 is formed with a pair of recesses 158 at the distal end portion thereof.
The cross-sectional shape of the tip portion of No. 7 was T-shaped. With this shape, the press-contact depth of the press-contact portion 157 can be regulated, and the press-contact can be stably pressed against the covered electric wire 62 transferred from the wiring mold 16 to the work 181.

The above embodiment is not limited to the above, but may be modified as follows. In the above-described embodiment, the guide blocks 18 and 19 are fixed to the frame 17 with the hexagonal bolts 26.
