Description

  The present invention relates to an electric wire processing apparatus and an electric wire processing method for cutting an insulating coating at a longitudinal end portion or an intermediate portion of an electric wire and stripping the insulating coating.

  2. Description of the Related Art Conventionally, an electric wire processing device (peeling device) that strips an insulation coating to connect a core wire to a terminal fitting or the like at a longitudinal end portion of a covered electric wire with an insulation coating on the core wire (for example, Patent Document 1) reference). Such an electric wire processing apparatus grips the electric wire sent out in the longitudinal direction by a clamp at a predetermined position, and cuts in the circumferential direction of the insulation coating by a pair of cutters sandwiching the longitudinal end portion of the electric wire from both sides. The insulation coating is removed by sliding the cutter relative to the direction end side.

  On the other hand, an electric wire processing apparatus (coating stripper) that cuts the insulating coating along the longitudinal direction of the electric wire and strips off the insulating coating is also used (for example, see Patent Document 2). In this processing apparatus, a guide tip is inserted between a core wire and an insulating coating in an electric wire, and the insulating coating is cut with a cutting blade provided adjacent to the guide tip. Patent Document 2 discloses an incision blade in which an electric wire is fixed and held by a concave portion having an R curved surface for receiving an electric wire and a J-shaped hook in addition to the incision blade that protrudes from the concave portion. An electric wire processing apparatus configured to pierce the insulating coating is also described.

  By the way, the stripping method for stripping the insulation coating from the electric wire is not limited to the method of pulling out the insulation coating by relatively sliding the electric wire and the cutter in the longitudinal direction as in the skinning device described in Patent Document 1. After cutting in the longitudinal direction of the electric wire as described in Patent Document 2, incision is made in the circumferential direction of the electric wire in accordance with the cutting position in the longitudinal direction, and the longitudinal and circumferential cuts are made continuous. Thus, the insulating coating is also stripped off. At this time, if the start point of the circumferential cut is made to match the cut in the longitudinal direction, the insulating coating can be easily and reliably peeled off by setting the matching portion as the peeling start point. Become.

  However, in the coating stripper described in Patent Document 2 described above, the cutting blade is moved manually along the longitudinal direction of the electric wire, so that the cut formed in the insulating coating is inclined with respect to the longitudinal direction of the electric wire. There is a problem that the cutting accuracy is inferior, for example, the cutting is shifted from a predetermined position in the circumferential direction. In addition, even when using an electric wire processing device that holds an electric wire drawn by a J-shaped hook in a recess, the cutting blade is stuck in the insulation coating before holding the drawn electric wire between the hook and the recess. Therefore, it is difficult to pierce the cutting blade at a predetermined position along the circumferential direction of the electric wire. As described above, in the conventional wire processing apparatus, since the longitudinal cut is not accurately formed at a predetermined position along the circumferential direction of the wire, the longitudinal cut and the starting point of the circumferential cut can be matched. There are problems such as difficulty in stripping the insulation coating and rough cutting of the insulation coating. The electric wire targeted by the present invention may be an unshielded electric wire with one or more core wires covered with an insulating coating, or a shielded electric wire with one or more core wires covered with a shield braid and covered with an insulating coating. There may be.

The electric wire can be appropriately moved in the circumferential direction while reducing the resistance, and the electric wire can be positioned between the rollers.

  The electric wire processing apparatus according to claim 4 is the electric wire processing apparatus according to any one of claims 1 to 3, wherein the cutting cutter has the blade built-in and can receive the electric wire. It is characterized by having a part.

  With the above configuration, the cutting cutter has a guide portion that can receive an electric wire, so that the blade incorporated in the guide portion is in contact with the insulating coating while the electric wire is received in the guide portion to prevent displacement. Can be formed.

The electric wire processing method of the present invention described in claim 5 is an electric wire processing method in which a cut along the longitudinal direction is made in the insulating coating of the electric wire, and the electric wire is connected from both sides in a direction intersecting the longitudinal direction of the electric wire. In a state where the cutting cutter is separated from the electric wire using a device provided with a positioning portion that is interposed and positioned, and a cutting cutter that is provided so as to be separated and approachable with respect to the electric wire, the electric wire is moved by the positioning portion.

  According to the third aspect of the present invention, since the electric wire can be positioned while reducing the frictional resistance by rolling the roller, the electric wire can be positioned without a large driving force. Furthermore, since the notch can be formed while the electric wire is positioned in the circumferential direction by the rotation of the driven roller by feeding the electric wire in the longitudinal direction, it is possible to ensure continuous incision in the longitudinal direction at a predetermined position in the circumferential direction of the electric wire. Can be formed.

  According to the fourth aspect of the present invention, the blade is brought into contact with the insulating coating while being guided by the guide portion to form a cut, so that a positional shift when the blade is brought into contact can be prevented. The accuracy can be further improved.

  The moving roller 22 is rotatably supported by a support plate 25. The support plate 25 includes a guide rail 26 fixed to the upper surface of the bottom plate 11 of the slide plate 5D, and a slider 27 guided by the guide rail 26. , And is urged toward the fixed roller 21 by a compression spring 28 inserted between the rear end plate 12 in a compressed state. By such a support plate 25, the moving roller 22 is moved away from the electric wire 90 by a holding position for positioning the electric wire 90 between the moving roller 22 and the fixed roller 21 by the forward or backward operation of the slide plate 5 </ b> D by the operation means 5 </ b> E. It can be moved forward and backward between the positions.

  As shown in FIGS. 7 and 8, respectively, the fixed roller 21 and the moving roller 22 are formed in the shape of a concave groove in which each peripheral surface is recessed in the radial center side and opened radially outward, and gradually toward the opening side. It is formed having a pair of inclined side surfaces 21A, 22A extending in the direction. Such rollers 21 and 22 position the electric wire 90 in the circumferential direction by bringing the pair of inclined side surfaces 21A and 22A into contact with the surface of the electric wire 90, as shown in FIG. That is, as shown in FIG. 8 (A), the two core wires 92 are opposed to each other (the direction indicated by the symbol A in FIG. 7), and the major axis of the cross section of the electric wire 90 is substantially oval or elliptical in the horizontal direction. The electric wire 90 is sandwiched between the fixed roller 21 and the moving roller 22 while rotating the electric wire 90 about the longitudinal direction so as to be parallel.

  The cutting cutter 30 includes a guide rail 31 fixed to the upper surface of the bottom plate 11 of the slide plate 5D, a cutter main body 32 supported slidably along the guide rail 31, and the cutter main body 32 toward the pressing roller 24. It has a compression spring 33 that urges and a standing plate 34 that supports the reaction force of the compression spring 33, and the cutter body 32 is supported so as to be movable forward and backward in the crossing direction with respect to the slide plate 5D. . The cutter body 32 is provided with a concave guide portion 35 that opens to the pressing roller 24 side and can receive the electric wire 90, and a pair of left and right contact rollers 36 across the guide portion 35.

  Such a cutter body 32 is moved forward together with the slide plate 5D by the operation of the operation means 5E, and the slide plate 5D is further advanced from the holding position where the moving roller 22 holds the electric wire 90, whereby the cutter blade 37 is moved. The insulation coating 91 of the electric wire 90 is brought into contact. In other words, in a state where the moving roller 22 moved to the holding position holds the electric wire 90, the cutter blade 37 is separated without contacting the insulating coating 91. By moving the slide plate 5D forward from this state, the cutter blade 37 moves. The roller 22 and the support plate 25 maintain the holding position against the urging force of the compression spring 28, and the cutter body 32 and the cutter blade 37 move forward relative to the moving roller 22 and bite into the insulating coating 91. In this way, the cut C is formed by biting the cutter blade 37 into the insulating coating 91.

The electric wire processing method using the above electric wire processing apparatus 1 is demonstrated below.
First, the electric wire 90 is inserted into the guide groove portion 3A of the electric wire guide portion 3, the distal end portion of the electric wire 90 is inserted into the insertion portion 3B, and the distal end of the electric wire 90 is brought into contact with the abutting portion 4A of the distal end positioning portion 4. By visually observing the position confirmation part 4B, it is confirmed that the tip of the electric wire 90 has been positioned. Next, the electric wire 90 is inserted into the receiving grooves 10 of the first guide portion 5B and the second guide portion 5C in the notch forming portion 5, and the pair of positioning portions 20 are fixed as shown in FIGS. 4 and 7A. An electric wire 90 is bridged between the roller 21 and the moving roller 22. In this state, the moving roller 22 is provided at a retracted position that is greatly separated from the fixed roller 21, and the cutting cutter 30 is provided at a separated position where the cutter body 32 is separated from the electric wire 90.

  At this time, as shown in FIG. 7A, the electric wire 90 rotates about the longitudinal direction as an axis, and the opposing direction of the two core wires 92 (the direction indicated by symbol A in FIG. 7) is the horizontal direction (fixed roller 21 and There is a case where it is arranged to be inclined with respect to the facing direction of the moving roller 22. Thus, in the state where the electric wire 90 is rotated and inclined, the notch C cannot be formed at the apex on one side in the opposing direction of the two core wires 92, which is inconvenient when the insulating coating 91 is peeled off. It is necessary to position the electric wire 90 in the circumferential direction.

  Specifically, the moving roller 22 is moved forward together with the slide plate 5D by the operating means 5E, and the inclined side surface 22A of the moving roller 22 is brought into contact with the surface of the electric wire 90 as shown in FIGS. 5 and 7B. Accordingly, the inclined side surfaces 21 </ b> A and 22 </ b> A of the fixed roller 21 and the moving roller 22 that are opposite to each other are brought into contact with the surface of the electric wire 90. Further, when the moving roller 22 is advanced, the electric wire 90 pressed by the inclined side surfaces 21A and 22A rotates. Then, as shown in FIG. 8A, when the opposing direction of the two core wires 92 is rotated to a position parallel to the horizontal direction, the upper and lower inclined side surfaces 21A and 22A ( That is, the four points are in contact with the surface of the electric wire 90, so that the electric wire 90 is stable in the rotational direction, the vertical direction in FIG. 5 (the horizontal direction in FIG. 8), and the depth direction in FIG. 5 (the vertical direction in FIG. 8). Will be positioned.

  When the moving roller 22 is moved to the holding position and the electric wire 90 is positioned in this way, the cutter blade 37 of the cutting cutter 30 is positioned at a separated position away from the insulating coating 91 as shown in FIG. Has been. Next, the cutter body 32 is further advanced together with the slide plate 5D by the operation means 5E, and the electric wire 90 is received between the side surface portions 35B of the guide portion 35 and the cutter blade 37 as shown in FIGS. Is brought into contact with the insulating coating 91, and the cutter blade 37 is inserted to a cutting position penetrating the insulating coating 91. At this time, the pressing roller 24 comes into contact with the other side of the electric wire 90, and the right and left contact rollers 36 come into contact with the one side of the electric wire 90 with the cutter blade 37 interposed therebetween, so that the displacement of the electric wire 90 can be prevented. It has become.

  In the state where the cutter blade 37 is inserted into the insulating coating 91 while positioning the electric wire 90 as described above, the electric wire 90 is pulled out from the electric wire processing apparatus 1 in the direction from the tip positioning portion 4 toward the cut forming portion 5. A notch C is formed along the longitudinal direction in the insulating coating 91 on the end portion side. After the electric wire 90 having the cut C formed in the insulating coating 91 is conveyed to the next processing step, the operating means 5E is operated to retract the moving roller 22 and the cutter body 32 together with the slide plate 5D to the retracted position. Processing is complete.

  According to the present embodiment, the electric wire 90 is positioned in the circumferential direction by being sandwiched between the fixed roller 21 and the moving roller 22, and then the cutter blade 37 of the cutting cutter 30 is inserted into the insulating coating 91, thereby The cut C can be accurately formed at a predetermined position in the direction. Therefore, for example, when forming a cut along the circumferential direction in the subsequent process with respect to the cut C along the longitudinal direction of the electric wire 90, the alignment of each cut can be ensured, and the cut can be reliably performed from the crossing position of the cuts. Since the insulating coating 91 can be stripped off, the stripping operation can be facilitated and the cut surface after stripping off can be neatly arranged.

  The pair of inclined side surfaces 21A and 22A formed on the fixed roller 21 and the moving roller 22 are positioned by abutting against the electric wire 90, so that the electric wire 90 has an odd-shaped cross section such as an ellipse or an oval. Even so, positioning can be ensured according to the thickness and cross-sectional shape. Further, the cutter blade 37 incorporated in the guide portion 35 is brought into contact with the insulating coating 91 while the electric wire 90 is received by the guide portion 35 of the cutting cutter 30, thereby preventing positional deviation when the cutter blade 37 is brought into contact. The position accuracy of the cut C can be further improved.
