[0012]

Embodiments of the present invention will be described below in detail with reference to the drawings. 1 to 5 show one embodiment of a shielded wire processing method according to the present invention.

In this method, first, as shown in FIG. 1, a shielded electric wire 1 is cut into a required length and set in a shielded electric wire processing device (not shown). Next, as shown in FIG. 2, at the end of the shielded electric wire 1, one of the shielded electric wires 1 (the side opposite to the end 1 a of the shielded electric wire 1) is fixed by the first electric wire clamp 2 and the first electric wire clamp 2. An annular die 3 is set in front of 2 and the shield wire 1 is inserted through the die 3.

In this state, the outer coating 5 of the shielded electric wire 1 is cut at the front end side of the die 3 by a pair of stripping cutters 4, 4, and the stripping cutters 4, 4 are brought into contact with the cut 5 a of the outer coating 5. The outer covering 5 is moved in the longitudinal direction forward (in the direction of the distal end 1a of the shielded electric wire 1) along the braid 6 by a fixed distance.

As a result, the middle portion in the longitudinal direction of the braid 6 is exposed, and the first half 5b of the outer sheath 5 projects forward from the front end 1a of the shielded electric wire 1. The rear half 5c of the outer covering 5 covers the braid 6. The die 3 has a small diameter portion 8 in the first half and a large diameter portion 9 in the second half. The peeling cutters 4 and 4 have a stroke setting in the closing direction so as to cut only the outer coating 1, and the braid 6 is not cut at all.

Next, the peeling cutters 4 and 4 are separated (avoided) from the shielded electric wire 1, and the rear half 5c of the outer sheath 5 is gripped by a second electric wire clamp 10 (electric wire clamp) as shown in FIG. To move the second wire clamp 10 to the exposed braid 6 side (rearward). The outer sheath 5 moves integrally with the second wire clamp 10. As a result, the longitudinal tubular braid 6 in FIG. 2 is compressed and gathered to expand the diameter into a substantially disk shape, and protrudes largely outward in the radial direction from the outer periphery of the tip 3 a of the die 3. The radial amount of protrusion of the braid 6 is determined by the amount of movement of the outer covering 5 by the peeling cutter 4 in FIG. The protruding amount of the braid 6 from the outer coating 5 is approximately one half of the moving amount of the peeling cutter 4, that is, the exposed length of the braid 6. The second wire clamp 10 grips the middle portion of the outer sheath 5 in the longitudinal direction. The cut 5a of the outer coating 5 moves until it approaches the tip 3a of the die 3.

Next, the second electric wire clamp 10 is separated from the shielded electric wire 1, the annular punch 11 is positioned in front of the die 3 as shown in FIG. Blade (edge) 1 inside
The disk-shaped braid 6 is cut into a circle with the blade 1a and the outer edge 8a of the die 3. The small diameter portion 8 of the die 3 enters along the inner diameter portion 12 of the punch 11. 6a is the braid 6
6b indicates an unnecessary braid projecting from the cut 5a of the outer coating 5.

Next, the punch 11 is released (avoided) from the shielded electric wire 1, and the pair of peeling cutters 4, 4 are brought forward against the cutout (rear end) 5a of the outer coating 5 as shown in FIG. The outer sheath 5 is moved integrally with the braids 6a and 6b, and is separated from the front end 1a of the shielded electric wire 1 forward along the inner sheath 7. Thereby, the peeling of the outer coating 5 and the cutting of the braid 6 are completed. At the front end of the outer coating 5 on the first wire clamp 2 side, the braid 6 remaining without being cut
Project radially annularly. The outer diameter of the braid 6 is equal to the inner diameter of the punch 11 (the outer diameter of the small diameter portion 8 of the die 3) in FIG.

As shown in FIGS. 2 and 3, the outer sheath 5 partially peeled is gripped by the second wire clamp 10 and returned in the opposite direction to the peeling, and the braid 6 is compressed in the axial direction to form an annular shape. The main feature of this embodiment is that the flexible braid 6 can be cut cleanly and reliably by the die 3 and the punch 11.

FIGS. 6 to 10 show a detailed structure of a die, a punch, and a periphery of the die in the shielded wire processing apparatus according to the present invention. The shielded wire processing device will be described later.

As shown in FIGS. 6 and 7, the die 15 is formed in an annular shape with a small diameter portion 16 in the first half and a large diameter portion 17 in the second half.
An electric wire insertion hole 18 is provided at the center. The small diameter portion 16 is formed thin, and has a blade portion 19 on the outside of the tip. Large diameter part 1
7 has a tapered wire guide surface 20 that is continuous with the wire insertion hole 18 at the rear end side thereof. An annular groove 21 is formed on the outer periphery of the large-diameter portion 17. A pair of pin holes 22 are formed, and a lead-out hole (lead-out path) 23 is formed from the annular groove 21 to the front end face 17a of the large diameter portion 17 (FIG. 6).

The die 15 is housed inside an annular holder 24. The total length of the holder 24 is set longer than the total length of the die 15. A ring plate 2 for removing braided cutting residue on the front end face 17a of the large diameter portion 17 of the die 15
5 are arranged in contact with each other. The ring plate 25 has a tapered inner diameter portion (opening) 26 through which the small diameter portion 16 of the die 15 is inserted. The outer diameter of the ring plate 25 is slightly larger than the outer diameter of the large diameter portion 17 of the die 15. It is set small. A pair of pin holes 27 are formed in the ring plate 25 in the axial direction. At the front end of the inner diameter portion 28 of the holder 24, a tapered guide surface 30 for the punch 29 (FIG. 6) is formed. The holder 24 is the device body 31
(FIG. 6). The punch 29 will be described later.

As shown in FIG. 7, a die 15 is
An air introducing hole 32 for the annular groove 21 and a screw hole 33 for fixing the die are formed. The air introduction hole 32 continues to the air supply pipe 34. A bolt 35 is screwed into the screw hole 33, and the bolt 35 enters the annular groove 21 as shown in FIG. 8 to position and fix the die 15.

A pair of pins 36 are inserted into the pin holes 22 and 27 of the die 15 and the ring plate 25, and each pin 3
An E-shaped ring 37 as a stopper is attached to both ends of 6. A compression coil spring (hereinafter referred to as a coil spring) 38 is elastically provided between the rear end surface of the die 15 and the E-shaped ring 37. The entire length of the pin 36 is longer than the entire length of the die 15.
The ring plate 25 is slidable along the pins 36 outside the small diameter portion 16 of the die 15 in the axial direction. In the free state, the pin 36 is urged rearward (pulled) by the coil spring 38, and the urging force causes the ring plate 25 to be in close contact with the front end face 17a of the large diameter portion 17 of the die 15 as shown in FIG. In addition, a bolt (not shown) can be used instead of the pin 36 and the E-shaped ring 37.

As shown in FIG. 8, the compressed air 39 is supplied to the air introducing holes 32.
The compressed air 39 pushes the ring plate 25 forward from the annular groove 21 through the outlet hole 23 against the pulling force of the pin 36 (the urging force of the coil spring 38). Thereby, the cutting waste (see reference numeral 6a in FIG. 4) of the braid attached to the die 15 is discharged forward.
At the same time, the compressed air 39 is supplied from the gap between the tapered inner diameter portion 26 of the ring plate 25 and the blade portion 19 of the die 15 and the gap between the outer circumference of the ring plate 25 and the inner diameter portion 28 of the holder 24. The air is blown out as shown by the arrow A, and the cutting dust of the braid is reliably blown off from the holder 24 by this air blow. The cutting waste of the braid is reliably removed by the synergistic effect of the ring plate 25 and the air blow. The inclined inner diameter portion 26 of the ring plate 25 secures a gap for blowing out compressed air and acts as a guide surface when the ring plate returns.
