Description

Stripping tool

Technical Field

The present invention relates to a stripping tool for stripping a coated member of a coated electric wire.

Background

Generally, a high-voltage overhead distribution line uses an electric wire (hereinafter, simply referred to as "coated electric wire") in which the periphery of a copper electric wire (core wire) composed of a copper stranded wire, an aluminum electric wire, and a thick single wire is coated with a coating member as an insulator such as resin or rubber.

In a process of connecting the end portions of the covered electric wires to the core wires of the other covered electric wires or fastening them with a sheath or the like, it is necessary to peel off the covering member of the necessary portion of the covered electric wires to expose the core wires of the base in order to secure the electric conduction property.

Therefore, conventionally, an operator manually peels off a covering member of the covered electric wire using a knife or the like, or peels off a covering material of the covered electric wire using a stripper.

Patent document 1 discloses a tool (stripper) capable of safely and easily stripping a covering member of a covered electric wire by remote operation, focusing on the fact that the work of stripping the covering member of the covered electric wire occupies a relatively large specific gravity in the maintenance work as described above.

Technical problem to be solved by the invention

However, in the peeling operation using the tool described in patent document 1, in order that the cutting edge provided in the tool body of the tool does not damage the core wire when peeling off the covering member of the covered electric wire, the cutting edge is disposed so as to protrude at a distance slightly smaller than the thickness of the covering member, and therefore, there is a problem that a part of the covering member is easily left.

In the tool described in patent document 1, the cutting edge of the blade for peeling off the covering member of the covered electric wire can cut the covering member in the axial direction of the covered electric wire, but there is a problem that it is difficult to cut the covering member in the circumferential direction of the covered electric wire when the tool is rotated with respect to the covered electric wire.

Therefore, a main object of the present invention is to provide a peeling tool capable of smoothly peeling a covering member and easily performing maintenance of a blade body.

Further, a peeling tool according to the present invention is preferably used for peeling a covering member of a covered electric wire in which a core wire is covered with the covering member, the peeling tool including: a stripping tool body provided with a grip having a grip portion for gripping the coated electric wire; a pushing shaft provided in the stripping tool body to be movable forward and backward toward the holder; a cutter body holding body having a cutter body holding member, and the position between the pushing shaft and the holding body moves forward and backward relative to the holding body along with the forward and backward movement of the pushing shaft; and a blade body held by the blade body holding member so as to be parallel to the covered electric wire held by the holding portion of the peeling tool body, the blade body including: an axial cutting blade formed so as to be narrowed in a thickness direction toward the coated electric wire gripped by the grip portion of the tool body for peeling, for biting and peeling the coating member along an axial direction of the coated electric wire; and a pair of circumferential cutting blades extending from both left and right ends of the axial cutting blade toward the coated electric wire held by the holding portion of the peeling tool body, and having distal end portions projecting toward the coated electric wire than lower end edges of the axial cutting blades for simultaneously biting into and cutting off the coated member along a circumferential direction of the coated member, wherein the pair of circumferential cutting blades are arranged so that an extending direction thereof is perpendicular to an extending direction of the axial cutting blade and the blades are formed so as to be narrower in a width direction as they face the coated electric wire, the axial cutting blade is formed integrally with the pair of circumferential cutting blades, and the pressing shaft has a regulating member for regulating forward and backward movement of the pressing shaft.

In the peeling tool according to the present invention, it is preferable that the pressing shaft has a first engaging portion on a side opposite to a side on which the cutter body holder is attached, the peeling tool main body has an arm portion extending in a direction opposite to a direction in which the holder is provided in a protruding manner and substantially perpendicular to an extending direction of the pressing shaft, one end side of the arm portion is connected to the peeling tool main body, and the other end side of the arm portion has a second engaging portion.

Preferably, the peeling tool according to the present invention includes a pair of guides disposed at both ends of the blade body holding member, the pair of guides determining a peeling position of the covering member and guiding the peeled covering member to be output in a fixed direction to prevent the peeled covering member from falling, the pair of guides having a bent portion on an inner surface of the blade body holding member side, lower ends of the falling prevention portions of the pair of guides located outside the bent portion facing each other toward an inner side of a center in a width direction of the blade body from the bent portion, and a width between the lower ends of the falling prevention portions being narrower than a width of the blade body holding member.

Preferably, the peeling tool according to the present invention includes a back surface side guide located on the back surface side of the peeling tool main body and disposed across between the pair of guides.

In the separation tool according to the present invention, it is preferable that the pair of guides is formed integrally with a back surface side guide located on the back surface side of the separation tool body and disposed across between the pair of guides.

According to the peeling tool of the present invention, since the pair of cutting blades for the circumferential direction is provided in addition to the cutting blades for the axial direction, when the peeling tool is rotated around the covered electric wire to peel the covered member, the covering member can be easily cut in the circumferential direction by the cutting blades for the circumferential direction, and thus the peeling operation of the covered member can be smoothly performed.

Further, according to the peeling tool of the present invention, since the axial cutting blade and the pair of circumferential cutting blades are integrally formed in the blade body, the axial cutting blade and the pair of circumferential cutting blades can be simultaneously replaced by replacing the blade body, and the blade body can be easily attached to the peeling tool without adjusting the positional relationship between the axial cutting blade and the pair of circumferential cutting blades.

Further, according to the peeling tool of the present invention, since the moving distance of the pressing shaft can be restricted in advance by the restricting member, the moving distance of the blade body holder can be set so that only the covering member can be peeled without damaging the core wire of the covered electric wire. Since the movement distance required to bite the blade into the coated electric wire to such an extent as not to damage the core wire (that is, the movement distance corresponds to the thickness of the coated member) is determined in advance based on the wire diameter of the coated electric wire, the position of the predetermined member can be determined based on the required movement distance.

Further, according to the peeling tool of the present invention, since the pressing shaft has the first engaging portion on the side opposite to the side on which the cutter body holder is attached, the peeling tool main body has the arm portion extending in the direction opposite to the direction in which the holder is provided in a protruding manner and substantially perpendicular to the extending direction of the pressing shaft, one end side of the arm portion is connected to the peeling tool main body, and the other end side of the arm portion has the second engaging portion, the peeling tool can be easily rotated once by the remote operation of the operating lever with the covered electric wire as the center by hooking the first engaging portion and the second engaging portion to the distal end engaging portion of the operating lever.

Further, according to the peeling tool of the present invention, since the pair of guides which determine the peeling position of the covering member and guide the peeled covering member so as to be output in the fixed direction are provided at both ends of the cutter body holding member, and the peeled covering member is prevented from falling off, the pair of guides have the bent portion on the inner surface of the cutter body holding member side, and the lower ends of the respective falling-off preventing portions of the pair of guides positioned outside the bent portion face each other toward the inside toward the center in the width direction of the cutter body with the bent portion as a starting point, and the width between the lower ends of the respective falling-off preventing portions is narrower than the width of the cutter body holding member, the peeled covering member stays between the lower ends of the falling-off preventing portions, and the falling off of the covering member can be prevented.

Further, according to the stripping tool of the present invention, since the stripping tool has the rear surface side guide positioned on the rear surface side of the stripping tool main body and disposed across between the pair of guides, the blade body is prevented from slipping on the outer periphery of the coated electric wire due to the blade body moving in the forward direction, and the axial direction cutting blade and the pair of circumferential direction cutting blades can be made to firmly bite into the coated member.

Further, according to the stripping tool of the present invention, since the right side guide and the left side guide which are the pair of guides are formed integrally with the back side guide which is positioned on the back side of the stripping tool main body and is disposed across between the pair of guides, the cutter body is prevented from moving in the forward direction and slipping on the outer periphery of the coated electric wire, and the axial direction cutting blade and the pair of circumferential direction cutting blades can be made to firmly bite into the coated member. Further, since the guide is integrally formed, the number of steps for attaching the guide can be reduced. In addition, the strength of the connection portion between the right side guide and the left side guide and the back side guide is increased as compared with the case where the back side guide is connected by another member.

Further, a plurality of guide mounting holes 38f are bored in both end surfaces of the cutter body holding member 38. For example, guide attachment holes 38f are provided in 3 locations of each end surface. The guide attachment holes 38f extend from the end surfaces toward the push shaft pivot attachment hole 38 c.

When the pressing shaft 14 is pivotally attached to the cutter body holder 16, the pivotally attaching portion 30 of the pressing shaft 14 is inserted into the pressing shaft pivotally attaching hole 38c of the cutter body holder 38. At this time, the retaining member 46 enters the groove 30a of the pivot portion 30 from at least one of the first retaining member insertion hole 38d and the second retaining member insertion hole 38e, and each retaining member 46 is supported so as to be sandwiched between the first support portion 30b and the second support portion 30c of the pivot portion 30. Thereby, the pivot portion 30 of the pressing shaft 14 is rotatably supported with respect to the cutter body holding member 38.

(e) Knife body

The cutter body 18 will be described with reference to fig. 10. Fig. 10 (a) is a front view showing a blade body used in the peeling tool shown in fig. 1. Fig. 10 (b) is a right side view thereof. In fig. 10, the height direction is a direction of a line connecting an upper end edge and a lower end edge opposite thereto when the cutter body 18 is mounted to the cutter body holding member 38. The width direction is perpendicular to the height direction and is a direction connecting a left end edge of the blade body 18 and a right end edge opposite thereto. The thickness direction is a direction perpendicular to both the height direction and the width direction and in which the blade holder 38 is screwed.

The cutter body 18 includes an axial cutting blade 18a, a pair of circumferential cutting blades 18b, and a circumferential cutting blade 18 c. The

circumferential cutting blades

18b and 18c are divided into a circumferential cutting blade 18b on the right side in front view and a circumferential cutting blade 18c on the left side in front view with the axial cutting blade 18a interposed therebetween. The length of the blade 18 in the width direction is substantially the same as the length of the blade holding member 38 in the width direction. One end (upper) side of the blade 18 is attached to the blade attachment portion 38a of the blade holding member 38 so that the blade 18 can be replaced. On the other end side (lower side) of the cutter body 18, an axial cutting blade 18a and

circumferential cutting blades

18b and 18c are formed. The pair of blades extend from both left and right ends of the axial direction cutting blade 18a toward the covered electric wire W gripped by the grip portion 22a of the peeling tool body 12, and have tip portions projecting toward the covered electric wire W than the axial direction cutting blade 18a, with respect to the circumferential

direction cutting blades

18b and 18 c. The

circumferential cutting blades

18b and 18c are disposed such that the extending direction of the

circumferential cutting blades

18b and 18c is perpendicular to the extending direction of the axial cutting blade 18 a. In the cutter body 18, an axial cutting blade 18a and a pair of

circumferential cutting blades

18b and 18c are integrally formed.

The axial cutting blade 18a is narrowed in the thickness direction of the blade as it goes to the lower end of the coated electric wire W gripped by the grip portion 22a of the peeling tool body 12. That is, the length between the front side and the back side of the blade is tapered so as to become gradually shorter toward the tip. Further, the axial direction cutting blade 18a is provided for biting into the covered member W2 along the axial direction of the covered electric wire W and then cutting.

The axial direction cutting blade 18a is attached to the blade body holding member 38 so that the extending direction of the blade is parallel to the coated electric wire W held by the peeling tool body 12, and when the blade body 18 is attached to the blade body holding member 38, the axial direction cutting blade 18a is provided to protrude from the other principal surface (lower surface) of the blade body holding member 38 toward the coated electric wire W held by the peeling tool body 12. The axial cutting blade 18a is preferably a single blade.

The

circumferential cutting blades

18b and 18c are divided into a circumferential cutting blade 18b on the right side in front view and a circumferential cutting blade 18c on the left side in front view with the axial cutting blade 18a interposed therebetween. The right-side cutting blade 18b for the circumferential direction and the left-side cutting blade 18c for the circumferential direction may extend in parallel. The right-end cutting blade 18b for the circumferential direction and the left-end cutting blade 18c for the circumferential direction have substantially the same shape.

The cutting blade 18b for circumferential direction has a tip end portion 18b1 and a support portion 18b 2. The cutting blade 18c for circumferential direction has a distal end portion 18c1 and a support portion 18c 2. The distal end portions 18b1 and 18c1 are portions provided to protrude from the cutting edge as the lower end edge of the axial cutting blade 18 a. The axial cutting blade 18a and the pair of

circumferential cutting blades

18b and 18c are integrally formed continuously with the axial cutting blade 18a in the supporting portion 18b2 of the circumferential cutting blade 18b and the supporting portion 18c2 of the circumferential cutting blade 18 c. The right circumferential cutting blade 18b and the left circumferential cutting blade 18c extend toward the coated electric wire W gripped by the grip portion 22a of the peeling tool body 12 and are directed toward the coated electric wire W more than the axial cutting blade 18a, and the front end portion 18b1 of the right circumferential cutting blade 18b and the front end portion 18c1 of the left circumferential cutting blade 18c may be provided to protrude in the same thickness as or longer than the thickness of the coating member W2. The right circumferential cutting blade 18b and the left circumferential cutting blade 18c are disposed such that the extending directions of the circumferential cutting blade 18b and the circumferential cutting blade 18c are perpendicular to the extending direction of the axial cutting blade 18 a. The front end 18b1 of the right-side cutting blade 18b for the circumferential direction and the front end 18c1 of the left-side cutting blade 18c for the circumferential direction are substantially V-shaped sharp-tipped blades in front view, substantially U-shaped (inverted コ -shaped) in side view, and have a sharp-tipped blade at the front corner and the rear corner, and the blade edge is linear and continuous from the front side to the rear side. Further, the right-side cutting blade 18b for the circumferential direction and the left-side cutting blade 18c for the circumferential direction are provided for simultaneously biting into the covering member W2 along the circumferential direction of the covered electric wire W and then cutting.

The supporting portion 18b2 of the circumferential cutting blade 18b and the supporting portion 18c2 of the circumferential cutting blade 18c are formed from the ridge 18g facing the cutting edge of the axial cutting blade 18a to the tip 18b1 of the right circumferential cutting blade 18b and the tip 18c2 of the left circumferential cutting blade 18c, and have a thickness equal to the length of the blade body supporting portion 18f in the thickness direction.

The right-side cutting blade 18b for the circumferential direction and the left-side cutting blade 18c define a range in which the covering member W2 of the covered electric wire W is peeled, that is, a length of the covered electric wire W in the axial direction. The

circumferential cutting blades

18b and 18c are preferably double-edged.

A blade mounting hole 18d is formed on one end edge (upper edge) side of the blade 18. When the cutter body 18 is mounted to the cutter body holding member 38, the cutter body mounting member 18e is passed through the cutter body mounting hole 18d and screwed to the cutter body mounting hole 38b of the cutter body holding member 38. In this way, the cutter 18 is mounted to the cutter mounting portion 38a of the cutter holding member 38. The cutter body mounting hole 18d is formed in a mortar shape so that the cutter body mounting member 18e does not protrude when the cutter body mounting member 18e is screwed into the cutter body mounting hole 18 d.

The cutter body supporting portion 18f is connected to the axial cutting blade 18a and the

circumferential cutting blades

18b and 18c, and supports the cutter body mounting hole 18 d.

(f) Guide member

The guide 40 and the guide 42 will be described based on fig. 9. Fig. 9 (a) is a front view showing a guide on the right side of the front view used in the peeling tool shown in fig. 1, and fig. 9 (b) is a right side view thereof. Fig. 9 (c) is a front view showing a guide on the left side of the front view used in the peeling tool shown in fig. 1, and fig. 9 (d) is a right side view thereof.

The pair of guides determines the peeling position of the covering member, guides the peeled covering member so as to be output in a fixed direction, and prevents the peeled covering member from falling, and the pair of guides is composed of a guide 40 and a guide 42.

The guide 40 is attached to the right end surface of the cutter body holding member 38. The guide 40 includes a guide body portion 40 a. The guide main body portion 40a is formed with a guide attachment hole 40a 1. When the guide 40 is mounted to the right end surface of the cutter body holding member 38, the guide mounting member 40a2 is inserted into the guide mounting hole 40a1 and screwed into the guide mounting hole 38f of the cutter body holding member 38. A stopper 40a3 is provided on the lower end side of the guide body 40 a. Further, a separation preventing portion 40b is provided in the front portion of the guide main body portion 40a so as to project inward and downward in the width direction of the cutter body 18 from the bent portion 40a 4. A rear surface side guide support portion 40c protrudes from the rear portion of the guide main body portion 40 a.

The guide 42 is attached to the left end surface of the cutter body holding member 38. The guide 42 includes a guide body portion 42 a. The guide main body portion 42a is formed with a guide mounting hole 42a 1. When the guide 42 is attached to the left end surface of the cutter body holding member 38, the guide attachment member 42a2 is inserted into the guide attachment hole 42a1 and screwed into the guide attachment hole 38f of the cutter body holding member 38. A stopper 42a3 is provided on the lower end side of the guide body 42 a. Further, a separation preventing portion 42b is provided in the front portion of the guide main body portion 42a so as to project inward and downward in the width direction of the cutter body 18 from the bent portion 42a 4. A rear surface side guide support portion 42c is provided projecting from the rear portion of the guide main body portion 42 a.

It is preferable that the bending portions 40a4 and 42a4 have grooves for bending, but the grooves for bending may not be formed.

The separation preventing portions 40b of the guide 40 and the separation preventing portions 42b of the guide 42 are provided so as to protrude forward and downward, and can be used to determine the position of the covering member W2 from which the covered electric wire W is to be separated.

The falling prevention portions 40b of the guide 40 and the falling prevention portions 42b of the guide 42 are provided so as to protrude forward and downward, and thus the covering member W2 of the stripped covered electric wire W can be guided so as to be output in a fixed direction.

Since the falling-off prevention portion 40b of the guide 40 and the falling-off prevention portion 42b of the guide 42 face each other from the bent portion 40a4 to the falling-off prevention portion 40b and from the bent portion 42a4 to the lower end of the falling-off prevention portion 42b inward toward the center in the width direction of the cutter body 18, respectively, the width between the lower end of the falling-off prevention portion 40b and the lower end of the falling-off prevention portion 42b is narrower than the width of the cutter body holding member 38, and therefore the coating member peeled off stays between the lower end of the falling-off prevention portion 40b and the lower end of the falling-off prevention portion 42b, and the coating member can be prevented from falling off.

As shown in fig. 2, the cutter body 18 is mounted closer to the peeling tool body 12 than the falling-off prevention portion 40b of the guide 40 and the falling-off prevention portion 42b of the guide 42 when viewed from the side. Thus, when the covering member W2 of the covered electric wire W is peeled off by the cutter body 18, the pair of cutting

blades

18b and 18c for the circumferential direction can be caused to bite into the covering member W2 prior to the guide 40 and the guide 42.

Of the lower end edges of the guide main body portion 40a, the lower end edge on the horizontal stopper portion 40a3 side is continuous with the horizontal lower end edge on the rear surface side guide support portion 40c side, which is higher than the lower end edge.

Similarly, of the lower end edges of the guide main body portion 42a, the lower end edge on the horizontal stopper portion 42a3 side is continuous with the horizontal lower end edge on the rear surface side guide support portion 42c side, which is one-piece higher than the lower end edge.

A back-side guide 44 is provided between the back-side guide support portion 40c of the guide 40 and the back-side guide support portion 42c of the guide 42. The rear surface side guide 44 is provided on the rear surface side of the main body portion 20, and may be formed in a rod shape as shown in fig. 4 (a).

Since the peeling tool 10 shown in fig. 1 is provided with the pair of

circumferential cutting blades

18b and 18c in addition to the axial cutting blade 18a, when the peeling tool 10 is rotated about the coated electric wire W to peel the coated member W2, the coated member W2 can be easily cut in the circumferential direction by the

circumferential cutting blades

18b and 18c, and thus the peeling operation of the coated member W2 can be smoothly performed.

In the peeling tool 10 shown in fig. 1, the cutter 18a for the axial direction of the cutter 18 and the

cutter

18b and 18c for the circumferential direction are integrally formed, and therefore the cutter 18 can be removed from the cutter holder 16 only by removing the cutter mounting member 18 e. Since all the blades required for peeling the covering member W2 can be replaced, adjustment for reattaching the cutter body 18 to the cutter body holder 16 is easy, and maintenance of the peeling tool 10 can be easily performed.

Further, the peeling tool 10 shown in fig. 1 has the regulating member 36, and the movement distance of the blade body holder 16 can be set so that the movement of the pressing shaft 14 in the advancing and retreating direction is regulated by the regulating member 36 before the operation, depending on the wire diameter of the coated electric wire W, and only the coating member W2 is peeled off without damaging the core wire W1.

Further, since the movement distance required to bite the blade into the coated electric wire W to such an extent as not to damage the core wire W1 (that is, the movement distance corresponds to the thickness of the coating member) is predetermined in accordance with the wire diameter of the coated electric wire W, the position of the regulating member 36 in the screw portion 28 can be determined based on the required movement distance.

Further, in the peeling tool 10 shown in fig. 1, since the main body portion 20 includes the arm portion 26b extending in the direction substantially perpendicular to the direction in which the holding body 22 protrudes and in which the pressing shaft 14 extends, one end side of the arm portion 26b is connected to the main body portion 20 via the arm support portion 26a, and the other end side of the arm portion 26b includes the second engaging portion 26c, the first engaging portion 34 and the second engaging portion 26c of the arm portion 26 are caught by the distal end engaging portion S2 of the operating lever S, and the peeling tool 10 can be easily rotated once about the coated electric wire W by the remote operation of the operating lever S.

Further, the peeling tool 10 shown in fig. 1 has a pair of

guides

40 and 42 disposed at both ends of the blade holder 38, the pair of

guides

40 and 42 determining the peeling position of the covering member W2, the peeled covering member W2 is guided so as to be discharged in a fixed direction, the peeled covering member W2 is prevented from dropping, the peeling tool 10 has inflected sections 40a4 and 42a4 on the inner surface on the blade body holding member 38 side, starting from the bent portions 40a4, 42a4, the fall-off preventing

portions

40b, 42b on the outer sides of the bent portions 40a4, 42a4 face each other toward the center in the width direction of the cutter body 18 on the inner sides, the width between the lower ends of the falling off

prevention parts

40b and 42b is narrower than the width of the cutter body holding member 38, therefore, the peeled covering member W2 stays between the lower ends of the fall-

off prevention portions

40b and 42b, and the falling-off of the covering member W2 can be prevented.

Further, since the peeling tool 10 shown in fig. 1 includes the back side guide 44, when the blade 18 peels the covering member W2 from the covered electric wire W, the blade 18 is prevented from moving in the forward direction and slipping on the outer periphery of the covered electric wire by the blade 18, and the axial direction cutting blade 18a and the pair of circumferential

direction cutting blades

18b and 18c can be made to firmly bite into the covering member W2 of the covered electric wire W.

2. Operating procedure of stripping tool

Next, an operation procedure of a peeling tool for mounting the peeling tool formed as described above to the coated electric wire W and peeling the coated member W2 from the coated electric wire W by using the peeling tool at a remote distance will be described. Fig. 11 to 18 are views for explaining a method of using the peeling tool shown in fig. 1, showing operation steps for peeling the covering member from the covered electric wire by the peeling tool.

(1) First, as shown in fig. 11, the distal end engaging portion S2 of the operating lever S is hooked on the ring portion 34a of the first engaging portion 34 of the peeling tool 10, and the peeling tool 10 is lifted by the operating lever S. Then, a part of the coated electric wire W is sandwiched between the curved surface 22b of the grip portion 22a of the peeling tool 10 lifted by the operating lever S and the

guides

40 and 42, and the peeling tool 10 is attached to the coated electric wire W.

(2) Next, as shown in fig. 12, the ring portion 34a of the first engagement portion 34 of the stripping tool 10 is pulled down by the operating lever S about the coated electric wire W, and the stripping tool 10 is hung from the coated electric wire W.

(3) Next, as shown in fig. 13 (a), in a state where the tip end engaging portion S2 of the operating lever S is caught on the first engaging portion 34, the first engaging portion 34 is rotated in the clockwise direction about the axis of the pressing shaft 14, and the pressing shaft 14 is rotated, whereby the blade body holder 16 is moved toward the coated electric wire W. At this time, the pushing shaft 14 is moved until the regulating member 36 fixed at a predetermined position of the screw portion 28 of the pushing shaft 14 abuts against the shaft support portion 24. As shown in fig. 13 (b), the axial cutting blades 18a and the

circumferential cutting blades

18b and 18c of the cutter body 18 bite into only the covering member W2 of the covered electric wire W.

(4) Next, as shown in fig. 14, the distal end engagement portion S2 of the operating lever S is turned to engage with the ring portion 26c1 of the second engagement portion 26c of the peeling tool 10.

(5) Next, as shown in fig. 15, the ring portion 26c1 of the second engagement portion 26c of the peeling tool 10 is pulled down around the covered electric wire W by the operating lever S, and the tip end engagement portion S2 of the operating lever S is pushed up to the right in a state of being engaged with the second engagement portion 26c of the peeling tool 10. At this stage, the stripping tool 10 is rotated about 240 ° about the coated electric wire W as an axial center.

(6) Next, as shown in fig. 16, the distal end engaging portion S2 of the operating lever S is turned to engage with the ring portion 34a of the first engaging portion 34 of the peeling tool 10.

(7) Next, as shown in fig. 17, in a state where the distal end engaging portion S2 of the operating lever S is engaged with the ring portion 34a of the first engaging portion 34 of the peeling tool 10, the ring portion 34a of the first engaging portion 34 is pulled down by the operating lever S about the covered electric wire W. At this time, the peeling tool 10 is further rotated about 120 ° about the coated electric wire W as an axial center. As a result, the stripping tool 10 rotates about 360 ° about the coated electric wire W as an axial center. Thereby, the covering member W2 is peeled off from the covered electric wire W over the entire circumference.

(8) Next, as shown in fig. 18, in a state where the distal end engaging portion S2 of the operating lever S is caught on the first engaging portion 34, the first engaging portion 34 is rotated counterclockwise about the axis of the pressing shaft 14, and the pressing shaft 14 is rotated, whereby the blade body holder 16 is moved in a direction away from the coated wire W side. Then, the peeling tool 10 is removed from the coated electric wire W.

As described above, the peeling tool 10 can be rotated once around the covered electric wire W. Fig. 19 is a perspective view illustrating a state in which the blade body is peeling the covering member from the covered electric wire. As shown in fig. 13 to 16, the stripping tool 10 rotates once, and the covering member W2 is stripped from the covered electric wire W. As shown in fig. 19, the covering member W2 is peeled off from the covered electric wire by the cutter body 18.

After the cutter body 18 is caused to bite into the covering member W2 of the covered electric wire W as shown in fig. 13 (b), as shown in fig. 19, an axial cutting line L1 of the covering member W2 is formed on the covering member W2 by the axial cutting blade 18a of the cutter body 18, and a circumferential cutting line L2 of the covering member W2 is formed by the

circumferential cutting blades

18b and 18c while the peeling tool 10 is rotated about the covered electric wire W.

3. Modification examples

Next, a modified example of the peeling tool according to another embodiment of the present invention will be described with reference to fig. 20 to 23. Fig. 20 is a rear view showing an example of the peeling tool according to the present invention. Fig. 21 is a right side view showing an example of the peeling tool according to the present invention. Fig. 22 is a plan view showing an example of the peeling tool according to the present invention. Fig. 23 (a) is a right side view showing a guide used in the peeling tool shown in fig. 20. Fig. 23 (b) is a front view showing a guide used in the peeling tool shown in fig. 20.

As shown in fig. 20 to 23, the peeling tool 10A according to this modification differs from the peeling tool 10 in that the left and right guides and the back surface side guide are integrally formed. The guide 80 used in the peeling tool 10A will be described. In addition, the same portions as those of the peeling tool 10 according to the above-described embodiment of the present invention are assigned the same reference numerals, and the same description will not be repeated.

The guide 80 includes a right side guide 82, a left side guide 84, and a back side guide 86, wherein the back side guide 86 is connected between the right side guide 82 and the left side guide 84, which are the back side of the main body 20. In the guide 80, the right side guide 82 is connected to the back side guide 86, and the left side guide 84 is connected to the back side guide 86, and has a substantially コ -shape in plan view.

The right guide 82 includes a guide main body portion 82 a. The guide body 82a has a guide attachment hole 82a 1. When the guide 80 is mounted to the right end surface of the cutter body holding member 38, the guide mounting member 82a2 is inserted into the guide mounting hole 82a1 and screwed into the guide mounting hole 38f of the cutter body holding member 38. Further, a detachment prevention portion 82b is provided in the front portion of the guide main body portion 82a so as to project inward and downward in the width direction of the cutter body 18 from the bent portion 82a 3.

The left guide 84 includes a guide main body portion 84 a. The guide main body portion 84a is formed with a guide mounting hole 84a 1. When the guide 80 is attached to the left end surface of the cutter body holding member 38, the guide attachment member 84a2 is inserted into the guide attachment hole 84a1 and screwed into the guide attachment hole 38f of the cutter body holding member 38. Further, a detachment prevention portion 84b is provided in the front portion of the guide main body portion 84a so as to project inward and downward in the width direction of the cutter body 18 from the bent portion 84a 3.

It is preferable that the bending portions 82a3 and 84a3 have grooves for bending, but the grooves for bending may not be formed.

By integrally forming the guide 80, when the cutter body 18 peels off the covering member W2 from the covered electric wire W, the cutter body 18 is prevented from moving in the forward direction and slipping on the outer periphery of the covered electric wire W by the cutter body 18, and the axial direction cutting blade 18a and the pair of circumferential

direction cutting blades

18b and 18c can be made to firmly bite into the covering member W2. Further, since the guide 80 is integrally formed, the number of steps for attaching the guide can be reduced. Further, the strength of the connection portion between the right and left side guides 82, 84 and the back side guide 86 is increased as compared with the case where the back side guide 86 is connected by another member.

As described above, the embodiments of the present invention are disclosed in the above description, but the present invention is not limited thereto.

That is, various modifications of the mechanism, shape, material, number, position, arrangement, and the like of the above-described embodiments can be made without departing from the technical spirit and scope of the present invention, and these are included in the present invention.

For example, in the peeling tool shown in fig. 1, the pressing shaft is screwed into the peeling tool body so as to be able to advance and retreat, but the pressing shaft may be provided in any manner in the peeling tool body as long as the pressing shaft is able to advance and retreat with respect to the peeling tool body.

In the peeling tool shown in fig. 1, the regulating member is screwed into the pressing shaft, but the present invention is not limited thereto, and the regulating member does not have to be screwed.

In the peeling tool shown in fig. 1, the arm is provided on the back surface side of the main body, but the present invention is not limited thereto, and the arm is not necessarily provided.

Further, in the peeling tool shown in fig. 1, the back surface side guide is disposed on the back surface side of the main body portion, but the present invention is not limited thereto, and the back surface side guide is not necessarily provided.

Claims

1. A peeling tool for peeling off a covering member of a covered electric wire formed by covering a core wire with the covering member, the peeling tool being characterized in that,

the peeling tool comprises:

a stripping tool body provided with a grip having a grip portion for gripping the coated electric wire;

a pressing shaft provided in the peeling tool main body so as to be movable forward and backward toward the holder;

a cutter body holding member having a cutter body holding member, the cutter body holding member being movable forward and backward relative to the holder along with forward and backward movement of the pressing shaft at a position between the pressing shaft and the holder; and

a blade held by the blade holding member so as to be parallel to the covered electric wire held by the holding portion of the peeling tool main body,

the cutter body has:

an axial cutting blade formed so as to be narrowed in a thickness direction toward the covered electric wire held by the holding portion of the peeling tool body, for biting into the covering member along an axial direction of the covered electric wire and peeling the covering member; and

a pair of circumferential cutting blades extending from both left and right ends of the axial cutting blade toward the covered electric wire held by the holding portion of the peeling tool body, each of the pair of circumferential cutting blades having a tip portion protruding toward the covered electric wire beyond a lower end edge of the axial cutting blade and configured to simultaneously bite into and cut off the covering member in a circumferential direction of the covering member,

the pair of circumferential direction cutting blades are arranged in such a manner that the extending direction thereof is perpendicular to the extending direction of the axial direction cutting blades and the blades are formed so as to be narrower in the width direction as they face the coated electric wire,

the axial cutting blade is formed integrally with the pair of circumferential cutting blades,

the peeling tool has a pair of guides disposed at both ends of the blade holding member,

the pair of guides determines a peeling position of the covering member, guides the peeled covering member so as to be output in a fixed direction, and prevents the peeled covering member from falling off, the pair of guides having a bent portion on an inner surface on the side of the blade holder,

the lower ends of the fall-off preventing portions of the pair of guides located outside the bent portion face each other toward the inside of the center of the cutter body in the width direction with the bent portion as a starting point, and the width between the lower ends of the fall-off preventing portions is narrower than the width of the cutter body holding member.

2. A peeling tool for peeling off a covering member of a covered electric wire formed by covering a core wire with the covering member, the peeling tool being characterized in that,

the peeling tool comprises:

the cutter body has:

the lower ends of the falling off prevention parts of the pair of guides located outside the bent part face each other toward the inner side of the center of the cutter body in the width direction with the bent part as a starting point, and the width between the lower ends of the falling off prevention parts is formed to be narrower than the width of the cutter body holding member,

the peeling tool includes a back surface side guide positioned on the back surface side of the peeling tool main body and disposed across the pair of guides.

3. A peeling tool for peeling off a covering member of a covered electric wire formed by covering a core wire with the covering member, the peeling tool being characterized in that,

the peeling tool comprises:

the cutter body has:

the pair of guides is formed integrally with the back surface side guide located on the back surface side of the separation tool body and disposed across between the pair of guides.

4. The peeling tool according to any one of claims 1 to 3,

the pushing shaft has a restricting member for restricting the forward and backward movement of the pushing shaft.

5. The peeling tool according to any one of claims 1 to 3, wherein the pressing shaft has a first engaging portion on a side opposite to a side on which the cutter body holder is attached,

the peeling tool body has an arm portion extending in a direction substantially perpendicular to an extending direction of the pressing shaft and opposite to a direction in which the holding body is provided in a protruding manner,

one end side of the arm portion is connected to the peeling tool main body, and the other end side of the arm portion has a second engagement portion.
