It has a concave cutting edge (also referred to as a second concave cutting edge) E1b.

  Furthermore, as FIG. 3 shows, the 1st blade part 21a and the 2nd blade part 21b are shifted and arrange | positioned in the direction (+ Y direction) where the electric wire 7 is extended. Thereby, for example, when the first blade portion 21a and the second blade portion 21b are approached in a state where the first concave blade edge portion E1a and the second concave blade edge portion E1b are directed to the electric wire 7, the first concave blade edge The electric wire 7 can be sandwiched between the part E1a and the second concave blade edge part E1b.

By doing so, the cutting and stripping of the electric wire can be performed quickly and easily.

<(3) Blade for wire processing>
FIG. 5 is an enlarged view of the first blade unit 21 including the first blade portion 21a and the second blade portion 21b.

  As shown in FIG. 5, the first concave cutting edge E1a has a first innermost part P1a, a first inclined part S1a, and a second inclined part S2a.

  The first innermost part P1a is the innermost part (also referred to as the innermost part) that is most recessed in the + Z direction as the first direction away from the second blade part 21b in the first concave blade edge part E1a. The first innermost portion P1a has a U-shape that is recessed in the first direction (+ Z direction).

  The first sloping portion S1a and the second sloping portion S2a are provided respectively from both end portions (also referred to as first end portions) EP1a and EP2a of a path (also referred to as an extending path) in which the first concave cutting edge E1a extends. 1 It forms a pair of inclined portions that incline in the first direction (+ Z direction) with reference to a line (also referred to as a first imaginary line) L1a that virtually connects the both end portions EP1a and EP2a over the innermost portion P1a. . More specifically, for example, the first inclined portion S1a extends from the end portion (also referred to as the first end portion) EP1a of the extending path of the first concave blade edge portion E1a to the first innermost portion P1a. As it approaches the first innermost part P1a, it is inclined with respect to the first virtual line L1a so as to be separated from the first virtual line L1a in the first direction (+ Z direction). Further, for example, the second inclined portion S2a is the first innermost portion from the + X side end portion (also referred to as the second end portion) EP2a of the extending path of the first concave cutting edge portion E1a to the first innermost portion P1a. As it approaches P1a, it inclines with respect to this 1st virtual line L1a so that it may leave | separate from the 1st virtual line L1a to a 1st direction (+ Z direction).

  Further, as shown in FIG. 5, the second concave cutting edge E1b has the same configuration as the first concave cutting edge E1a. However, here, the first concave cutting edge E1a and the second concave cutting edge E1b have a relationship such that the top and bottom and the front and back are reversed. That is, the first concave cutting edge E1a and the second concave cutting edge E1b have a two-fold rotational symmetry relationship with a straight line parallel to the X axis as the rotation axis.

  Specifically, the second concave cutting edge E1b has a second innermost portion P1b, a third inclined portion S1b, and a fourth inclined portion S2b.

  The second innermost part P1b is the innermost part (the innermost part) that is most recessed in the −Z direction as the second direction away from the first blade part 21a in the second concave blade edge part E1b. The second innermost portion P1b has a U-shape that is recessed in the second direction (−Z direction).

  The third inclined portion S1b and the fourth inclined portion S2b are provided on the second outermost ends (also referred to as second both end portions) EP1b and EP2b of the path (extended path) in which the second concave cutting edge E1b extends. A pair of inclined portions that respectively incline in the second direction (−Z direction) with respect to a line (also referred to as a second imaginary line) L1b that virtually connects the second end portions EP1b and EP2b over the back portion P1b. ing. More specifically, for example, the third inclined portion S1b extends from the −X side end portion (also referred to as a third end portion) EP1b of the extending path of the second concave blade edge portion E1b to the second innermost portion P1b. As it approaches the second innermost portion P1b, it is inclined with respect to the second virtual line L1b so as to be separated from the second virtual line L1b in the second direction (−Z direction). Further, for example, the fourth inclined portion S2b is the second innermost portion from the + X side end portion (also referred to as the fourth end portion) EP2b to the second innermost portion P1b of the extending path of the second concave cutting edge portion E1b. As it approaches P1b, it inclines with respect to the 2nd virtual line L1b so that it may leave | separate from the 2nd virtual line L1b in the 2nd direction (-Z direction).

  The 1st blade part 21a and the 2nd blade part 21b which have the said structure pinch | interpose the electric wire 7 with the 1st blade part 21a and the 2nd blade part 21b as a some blade part, The conductor part 71 of this electric wire 7 It is applied to the stripping process in the electric wire processing apparatus 100 that cuts the covering portion 72 arranged around the periphery of the cover portion and removes a cylindrical part of the covering portion 72.

  Here, for example, when the first blade portion 21a and the second blade portion 21b are approached by the first moving mechanism 4 and the electric wire 7 is sandwiched between the first blade portion 21a and the second blade portion 21b, the electric wire The first to fourth inclined portions S1a, S1b, S2a, S2b and the first and second innermost portions P1a, P1b can be cut around the conductor portion 71 of the seven covering portions 72. At this time, for example, as illustrated in FIG. 6, a gap Gp1 may be generated between the first innermost portion P1a and the second innermost portion P1b that are recessed in a U shape in a direction away from each other. Due to the presence of the gap Gp1, the first concave blade edge E1a and the second concave blade edge E1b can be cut around the conductor portion 71 in the covering portion 72 of the electric wire 7 so as to avoid the conductor portion 71. . Therefore, since the U-shaped innermost part is provided in the opposing concave cutting edge part, for example, it becomes possible to make a cut along the peripheral surface of the electric wire 7 in the covering part 72, and thus the electric wire 7. Can be successfully performed.

  Further, if the first concave blade edge portion E1a and the second concave blade edge portion E1b have shapes that extend in a semicircular shape, the gap Gp1 tends to be substantially circular. Thereby, for example, it becomes possible to make a cut along the peripheral surface of the conductor portion 71 of the electric wire 7 in the covering portion 72, and the accuracy of peeling of the electric wire 7 can be improved. The semicircular shape referred to here may include a semi-elliptical shape that is slightly flattened. Here, for example, the first blade portion 21 a and the second blade portion 21 b may be designed so that the gap Gp <b> 1 becomes a substantially circular shape along the cross-sectional shape of the conductor portion 71.

  In addition, here, for example, if the first inclined portion S1a and the second inclined portion S2a are directly connected to the first innermost portion P1a, the first blade is removed when the electric wire 7 is stripped. The distance for moving the portion 21a and the second blade portion 21b can be shortened. Similarly, for example, if the third inclined part S1b and the fourth inclined part S2b are directly connected to the second innermost part P1b, the first blade is used when the electric wire 7 is stripped. The distance for moving the portion 21a and the second blade portion 21b can be shortened. By shortening the movement distance of the first blade portion 21a and the second blade portion 21b as described above, the time required for stripping the electric wire 7 can be reduced, the energy consumption can be reduced, and the electric wire processing apparatus 100 can be downsized. obtain. In addition, for example, it is possible to easily set the movement distance of the first blade portion 21a and the second blade portion 21b in the skinning process.

  Here, as shown in FIG. 5, when the first concave cutting edge E1a is viewed in plan from the second concave cutting edge E1b side (−Z side), the extending direction of the first concave cutting edge E1a (+ X direction) ) Is a distance between both end portions EP1a and EP2a, that is, a length of the first concave cutting edge portion E1a in the + X direction is L1. Further, when the first concave cutting edge E1a is viewed in plan from the second concave cutting edge E1b side (−Z side), the first innermost portion P1a in the extending direction (+ X direction) of the first concave cutting edge E1a. The distance between both ends, that is, the length of the first innermost portion P1a in the + X direction is L2. At this time, if the length L1 is larger than the diameter D1 of the covering portion 72 and the length L2 is less than the diameter D1 of the covering portion 72 and is equal to or larger than the diameter D2 of the conductor portion 71, the first concave cutting edge E1a. Accordingly, it is possible to make a cut along the peripheral surface of the covering portion 72 in the covering portion 72 without making a cut in the conductor portion 71 of the electric wire 7. As a result, the accuracy of peeling of the electric wire 7 can be improved.

  Furthermore, as shown in FIG. 5, when the second concave cutting edge E1b is viewed in plan from the first concave cutting edge E1a side (+ Z side), in the extending direction (+ X direction) of the second concave cutting edge E1b. The distance between both end portions EP1b and EP2b, that is, the length of the second concave cutting edge portion E1b in the + X direction is L3. Moreover, when the 2nd concave blade edge part E1b is planarly viewed from the 1st concave blade edge part E1a side (+ Z side), both ends of the 2nd innermost part P1b in the extending direction (+ X direction) of the 2nd concave blade edge part E1b Let L4 be the distance between the portions, that is, the length of the second innermost portion P1b in the + X direction. At this time, if the length L3 is larger than the diameter D1 of the covering portion 72 and the length L4 is less than the diameter D1 of the covering portion 72 and is equal to or larger than the diameter D2 of the conductor portion 71, the second concave cutting edge E1b. Accordingly, it is possible to make a cut along the peripheral surface of the covering portion 72 in the covering portion 72 without making a cut in the conductor portion 71 of the electric wire 7. As a result, the accuracy of peeling of the electric wire 7 can be improved.

Due to the presence of the gap Gp1, the first concave cutting edge E1a and the second concave cutting edge E1b can be cut around the conductor portion 71 in the covering portion 72 so as to avoid the conductor portion 71. Therefore, any occurrence of damage to the conductor portion 71 and burrs on the covering portion 72 can be suppressed. That is, the stripping of the electric wire 7 can be performed satisfactorily.

<(6) Modification>
It should be noted that the present invention is not limited to the above-described embodiment, and various changes and improvements can be made without departing from the gist of the present invention.

  For example, in the said embodiment, although the 1st blade part unit 21 and the 2nd blade part unit 22 were formed as a different body, it is not restricted to this. For example, the 1st blade part 21a and the 3rd blade part 22a may be comprised integrally, and the 2nd blade part 21b and the 4th blade part 22b may be comprised integrally. Thereby, for example, attachment work and replacement work of the wire processing blade for processing the electric wire 7 in the electric wire processing apparatus can be facilitated. FIG. 13 is a front view schematically showing a wire processing blade 2aA in which a first blade portion 21a and a third blade portion 22a are integrally formed as a modification of the wire processing blade. FIG. 13 shows a state in which the first blade portion 21a and the third blade portion 22a are integrated by the connecting portion 2c.

  Further, the first to fourth inclined portions S1a, S1b, S2a, S2b may be formed linearly, or may be formed curved, such as curved.

  Moreover, in the said embodiment, although the 1st blade part unit 21 and the 2nd blade part unit 22 were moved relatively with respect to process implementation area | region A1 by the 2nd moving mechanism 5, it is not restricted to this. For example, the electric wire 7 may be moved without moving the first blade unit 21 and the second blade unit 22. That is, it is only necessary that at least one of the plurality of blade units 21 and 22 and the electric wire 7 is movable. At this time, the first blade unit 21 and the second blade unit 22 are moved relative to each other so that the first blade unit 21 and the second blade unit 22 are processed. Region A1 may be set. Even in such a configuration, since the second blade unit 22 for cutting the electric wire 7 and the blade unit 21 for stripping the electric wire 7 are arranged, the electric wire is cut and peeled. Stripping can be performed quickly and well.

  Moreover, in the said embodiment, although the 1st blade part unit 21 and the 2nd blade part unit 22 were provided, it is not restricted to this. For example, the second blade unit 22 may be removed from the first blade unit 21 and the second blade unit 22. That is, for example, an electric wire processing apparatus having the first blade unit 21 may be employed. Further, for example, a plurality of first blade unit 21 may be provided in the electric wire processing apparatus. Further, for example, the number of units may be arbitrarily set such that two first blade unit 21 and one second blade unit 22 are provided.

  As mentioned above, although this invention was demonstrated in detail, above-described description is an illustration in all the aspects, Comprising: This invention is not limited to it. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
