Description

  The present invention relates to a tool that is attached to a rotary tool and strips a coating.

  Conventionally, a cable having a coating layer formed around a conducting wire, such as a CV cable, a CVD cable, a CVT cable, or a CVQ cable, is generally used as a trunk cable between an electric power company and a distribution board. The CV cable is an abbreviation for a crosslinked polyethylene insulated vinyl sheath cable. As shown in FIG. 1, the CV cable 50 is a cable in which a conducting wire 51 is covered with a crosslinked polyethylene 52a and a vinyl sheath 52b. CVD cables, CVT cables, and CVQ cables are power cables obtained by twisting single-core CV cables in order to improve workability and allowable current value. A cable using two stranded wires is called a CVD cable, a cable using three stranded wires is called a CVT cable, and a cable using four stranded wires is called a CVQ cable.

  During construction, these cables are peeled off from a cross-linked polyethylene covering layer and a vinyl sheath covering layer (hereinafter collectively referred to as a “covering layer”), and are connected to a necessary portion by exposing a conductive wire. The coating layer, especially the cross-linked polyethylene coating layer is hard and difficult to peel off, and there is no work space in the distribution board. Therefore, work with hand tools such as cutters and electric knives is inefficient, and workers It is easy to get hurt. For this reason, cable sheath strippers that have various driving devices or are used by being connected to the driving devices have been proposed.

  As described above, in Patent Documents 1 to 5, the cutter protrudes from the inner peripheral surface of the cylindrical main body, and the cable covering layer is peeled off. For example, forming an exposure length regulating means is described.

  However, if the operator pushes off the coating layer too quickly and the force with which the rotary tool is pushed into the cable becomes excessive, the cutting width when the coating layer is peeled off by the cutter will be larger than expected, and the coating layer will be discharged. It becomes difficult. In particular, if the coating layer chips get stuck inside the cable coating stripping tool, not only will the work be interrupted, but in the worst case, the connection to the rotating tool (usually the hexagonal shaft) will be damaged. There's a problem.

  The present invention has been made in order to solve such a problem of the prior art, and by improving the workability by preventing clogging of chips of the coating layer, the connecting portion to the rotary tool is provided. It aims at providing the cable coating stripping tool which can reduce the failure | damage of a cable.

  In order to achieve the above-mentioned object, the present inventors have intensively studied the structure of a cutter for stripping the cable coating. For example, Patent Documents 1 to 4 basically employ a cutter that has only a scissors blade portion having a blade surface on the discharge port side provided on the peripheral surface of the main body. It becomes difficult to regulate the cutting width when the layer is peeled off. In patent document 5, the cutter which has the cutting blade part formed along the main body radial direction and the scooping blade part formed along the main body axial direction is used. It is integrally formed. If it is a cutter of such a structure, compared with the cutter with only the above-mentioned scissors blade part, it will be easy to regulate cutting width.

  However, the cutter disclosed in Patent Document 5 is “the cutting blade portion 22 and the scooping blade portion 23 are connected at right angles, and their connection point is defined as the cutting edge 26 of the cutting blade 15” (paragraph 0019 of Patent Document 5). The blade surfaces of the cutting blade portion and the scooping blade portion are provided so as to be adjacent to each other (see also FIG. 2 of Patent Document 5). That is, the blade surface of the cutting blade portion is formed on the surface opposite to the cable insertion port.

  As shown in FIG. 2A, in the cutter in which the blade surface 2a of the cutting blade portion is formed on the surface opposite to the insertion port (not shown) of the cable 50, when removing the coating of the cable, A force acts in a direction (in the direction of the arrow in the drawing) in which the cable 50 is fed inward. As a result, it is easy for the operator to send the cable, and the cut width when the covering layer is peeled off may exceed the expected value. On the other hand, as shown in FIG. 2B, in the cutter in which the blade surface 2 a of the cutting blade portion is formed on the surface on the insertion port (not shown) side of the cable 50, the covering of the cable 50 is removed. In doing so, the force acts in the direction in which the cable 50 is pulled back to the insertion port side (the direction of the arrow in the figure), so that the cutting width can be more reliably regulated. As a result, it becomes possible to prevent clogging of chips of the coating layer, and the workability can be remarkably improved and the breakage of the connecting portion to the rotary tool can be reduced.

  As described above, the cutter shown in Patent Document 5 is such that “the cutting blade portion 22 and the scooping blade portion 23 are connected at right angles, and their connection point is defined as the cutting edge 26 of the cutting blade 15”. However, for example, as shown in FIGS. 3A and 3B, a steel square is manufactured by high-precision cutting. However, in order to form a precise blade surface, the cutter material that is chucked on the machine tool itself is required to have a precise shape. For example, precise cutting is difficult unless cutting is performed from a solid material such as a cubic solid steel material with high right-angle accuracy or an angle with high right-angle accuracy. Therefore, the manufacture of the cutter as shown in FIGS. 3A and 3B necessitates precise cutting, resulting in an increase in manufacturing cost. In this regard, if the cutter surface 2a of the cutting blade portion is formed on the surface on the insertion port (not shown) side of the cable 50 as shown in FIG. It can be manufactured by ordinary cutting or polishing.

  This invention is made | formed based on such knowledge, and makes a summary the following cable coating stripping tool.

  (1) A tool for stripping the coating of a cable in which a coating layer is formed around a conducting wire, the coating layer being stripped on the peripheral surface of an insertion port for inserting the cable at one end in the axial direction A hollow shaft-shaped main body portion each having a discharge port for discharging chips, and a cutter having a blade edge protruding from the discharge port to the inner peripheral surface of the main body portion, the cutter having the insertion port A cable coating stripping tool having a cutting blade portion having a blade surface on the side and a scissors blade portion having a blade surface on the discharge port side.

  (2) The cable coating stripping tool according to (1), wherein the cutter is formed by forming a blade surface of a cutting blade portion and a scissors blade portion on a bent plate material.

  According to the cable coating stripping tool according to the present invention, since the cutting width of the coating layer can be regulated, clogging of chips of the coating layer can be prevented. As a result, the opportunity to interrupt the work to remove chips and the opportunity to break the connection to the rotary tool can be greatly reduced, and the efficiency of the cable sheath stripping work is greatly improved. be able to. And if it comes to the preferable aspect of this invention, it will become possible to manufacture the cutter for cable coating stripping tools cheaply.

  The embodiment of the cable coating stripping tool according to the present invention will be described with reference to the drawings.

  As shown in FIGS. 4 to 6, the cable coating stripping tool 10 according to the present invention includes a hollow shaft-shaped main body 1 and a cutter 2. The main body 1 has an insertion port 1a for inserting a cable 30 having a coating layer 30b formed around the conducting wire 30a at one end in the axial direction, and a discharge for discharging the stripped coating layer on the peripheral surface. And an outlet 1b. The cutter 2 has blade edges 2 a and 2 d protruding from the discharge port 1 b to the inner peripheral surface 3 c of the main body 1.

  As shown in FIG. 6, the cutter 2 is a substantially L-shaped cutter having a cutting edge portion having a blade surface 2d on the insertion port 1a side and a scissors blade portion having a blade surface 2a on the discharge port 1b side. It is. In this cutter 2, as shown in FIG. 5 (b), first, the coating layer 30b is cut by the vertical cutting edge 2d, and the scraped chips 30e are separated from the conductor 30a by the horizontal cutting edge 2a. Since it is lifted, it is easy to be discharged from the discharge port 1b as it is.

  Since such a cutter 2 is used in the cable sheath stripping tool 10 according to the present invention, when removing the sheath of the cable (not shown), a force acts in the direction of pulling the cable back toward the insertion port 1a. Therefore, it becomes possible to more reliably regulate the cutting width. As a result, it becomes possible to prevent clogging of the chips of the coating layer, greatly improving workability and reducing breakage of the connecting portion to the rotary tool.

  If the cutter 2 has a cutting edge portion having a blade surface 2d on the insertion port 1a side and a scissors blade portion having a blade surface 2a on the discharge port 1b side, for example, without depending on high-precision cutting, It can also be manufactured by forming the blade surface 2d of the cutting blade portion and the blade surface 2a of the scissors blade portion on the bent plate material. The manufacturing method will be described later, but if each blade surface is formed on a bent plate material, it can be manufactured by ordinary cutting, polishing, or the like.

  In the cable covering stripping tool 10 of the present invention, the inner peripheral surface 1 c of the main body 1 is covered with the first restricting means 3 for restricting the cutting width 30 c when the covering layer is stripped by the cutter 2 and the covering by the cutter 2. It is preferable that a second restricting means 4 for restricting the exposed length 30d of the conductive wire after peeling off the layer is provided.

  As shown in FIG. 5 (a), in the cable covering stripping tool 10 according to the present invention, first, the tip of the cable 30 is inserted into the insertion port 1a, and in that state, as shown in FIG. 5 (b), When the main body 1 is rotated around its axis while pushing the cable 30 into the insertion port 1a, the covering layer 30b of the cable 30 is peeled off. At this time, if the cable regulating stripping tool 10 is provided with the first restricting means 3, the cutting width 30c of the coating layer 30b of the cable 30 does not exceed a certain value. For this reason, clogging of the chip 30e of the coating layer can be prevented, and the efficiency of the cable coating peeling operation can be significantly improved.

  Subsequently, when the stripping operation of the covering layer 30b is further advanced while pushing the cable 30 into the insertion port 1a, as shown in FIG. 5C, if the second regulating means 4 is provided, the exposed conductor The tip of 30a abuts on the second restricting means 4 and cannot be pushed deeper than that. Thereby, it becomes possible to regulate the exposed length 30d of the conducting wire 30a after the coating layer 30b is peeled off by the cutter 2. Here, the 2nd control means 4 may be fixed by the fixed depth. The second restricting means 4 may be fixed by a known method such as welding or pressure bonding, or the second restricting means 4 may be made of a magnetic material and joined to the inner bottom portion of the main body 1 by its magnetic force. It is preferable that the 2nd control means 4 has a mechanism which can adjust the position especially. This is because, if such a mechanism is provided, the exposed length 3d of the conducting wire 30a can be adjusted.

  In addition, as a position adjustment mechanism of the 2nd control means 4, the system does not ask | require, such as the method of providing a hole in the radial direction of the main-body part 1 at predetermined intervals, and inserting a pin there, for example. A preferred configuration of the position adjusting mechanism will be described in detail later.

  Here, the 1st control means 3 may control the cutting width 30c at the time of peeling of the coating layer 30b to below the axial direction length (code | symbol 2c of FIG. 6) of the blade surface 2a of a scissors blade part. preferable. This is because by providing the first restricting means 3 at such a position, the chips 30e of the coating layer can be easily discharged. Although there is no restriction | limiting in particular in the form of the 1st control means 3, For example, as shown in FIG.5 (c), the surface (henceforth a "sliding surface") where the front-end | tip of the coating layer 30b slides. However, what is formed continuously over substantially the entire circumference of the inner surface of the main body 1 is preferable. Of course, the sliding surface of the 1st control means 3 may be divided | segmented into plurality. However, it is important that the coating layer does not hinder the smooth rotation of the coating layer 30b.

  The discharge port 1b is not limited as long as at least the cutting edge 2a of the cutter 2 can be visually recognized from the outside and can discharge the chip 30e of the coating layer. In particular, the axial rear end of the cutting edge 2a of the cutter 2 (FIG. 4 ( a) It is preferable to have a space in which the chips 30e can be discharged rearward (leftward in FIG. 4A and FIG. 5) from the left end of the blade edge 2a in FIG.

  Even with the configuration of the present invention, if the pushing force of the cable 30 into the insertion port 1a is too strong, the cutting width 30c may be slightly larger than the axial length of the blade edge 2a. However, even in such a case, if the discharge port 1b has a space in which the chips 30e can be discharged from the rear end in the axial direction of the cutting edge 2a of the cutter 2, the chips 30e of the coating layer can be discharged. There is no hindrance to discharge.

  As shown in FIG. 5, the cable covering stripping tool 10 according to the present invention can perform the stripping operation of the cable covering by manually rotating the main body 1. If it is set as the structure which has the tool connection part 5 in an other end, it will become possible to connect and use with a rotary tool (illustration omitted).

  The tool connecting portion 5 may be configured to have a hexagonal shaft bit 5a as shown in FIG. 5 or the like when using a rotary tool whose connecting portion is a hexagonal hole, such as an impact driver. For example, when using a rotary tool in which the connecting portion is formed of a quadrangular prism, a configuration having a square hole (not shown) may be used. In particular, in the case of a configuration having the bit 5a, a configuration in which the bit 5a is press-fitted and fixed to the opposite end of the insertion port 1a may be employed, but a configuration having a bit connection hole 5b for connecting the bit 5a may be employed. In particular, the bit connection hole 5b is preferably configured so that the bit 5a can be attached and detached.

  The cable size ranges from about 9.4 mm to about 31 mm in outer diameter, but the exposed length 30d of the conducting wire 30a varies depending on the size of the cable. If it is the structure which can adjust the position of the 2nd control means 4, it will become possible to finish to the exposure length 30d suitable for each size. Therefore, it is possible to basically perform several types of cable stripping work with the same outer diameter with a single cable stripping tool.

  As a configuration capable of adjusting the position of the second regulating means, for example, the configuration of FIG. 7 can be employed. That is, the cable coating stripping tool 10 a has a position adjusting mechanism 6. The position adjusting mechanism 6 includes a sleeve 6a, a locking member 6b having corrugated irregularities, a spring 6c, and a shaft portion 6d. The shaft portion 6d includes a second restricting means 4 at one end, a bit attaching / detaching means 7 having a bit connection hole at the other end, and a locking portion 6e made of corrugated irregularities at the center.

  Here, in the position adjusting mechanism 6, the sleeve 6a is urged in the axial direction (in the left or right direction in the figure, in the example shown in the figure, in the right direction) by a built-in spring 6c. The locking member 6b is pushed by the recess 6f on the inner surface of the sleeve 6a and is in contact with the locking portion 6e. At this time, corrugated irregularities formed on both the locking member 6b and the locking portion 6e are engaged, and movement in the axial direction is restricted. On the other hand, when the sleeve 6a is moved in the axial direction (left or right direction in the figure, left direction in the example shown) against the bias of the spring 6c, the built-in locking member 6b moves backward. Since it is separated from the locking portion 6e, the shaft portion 6d can be moved. In this state, the position of the second restricting means 4 can be adjusted. At this time, a scale or other mark is preferably attached to the shaft portion 6d. This is because the second restricting means 4 can be easily adjusted to the target position.

  The bit attaching / detaching tool 7 is for inserting the bit 8 into the bit connecting hole and connecting it to a rotary tool (not shown), and the bit 8 is detachably gripped. The sleeve 7a of the bit attaching / detaching tool 7 is urged in a left or right direction in the drawing by a built-in spring (not shown), and when moved against the urge, a built-in locking member ( A ball, a pin, a polyhedron, etc. (not shown) are retracted, the bit 8 can be removed, and the bit 8 is held by returning the sleeve 7a to the original position while the bit 8 is inserted.

  The bit attaching / detaching tool 7 is not essential, and may be press-fitted and fixed to the shaft portion 6d. However, if the bit breaks, the entire cable covering stripping tool must be replaced, increasing the replacement cost. For this reason, the structure provided with the bit attachment / detachment tool 7 is preferable.

  The bit 5 a may have a configuration in which one end is used for connection to a rotary tool (not shown) and the other end is used as the second restricting means 4. With such a configuration, the number of parts can be reduced, which contributes to a reduction in manufacturing cost. Moreover, it can prevent that the front-end | tip of a cable contacts and damages the inner bottom part of the main-body part 1 at the time of use. In particular, if it has a mechanism that can change the attachment position of the bit 5a to the bit connection hole 5b, the position of the second restricting means 4 can be adjusted, so that the exposed length 30d of the conducting wire 30a can be adjusted. In particular, the exposed length 30d of the conducting wire 30a can be adjusted at low cost if it has a mechanism that can change the attachment position of the bit 5a to the bit connection hole 5b.

There is no particular limitation on the mechanism for changing the mounting position of the bit 5a to the bit connection hole 5b.
(A) As shown in FIG. 8A, a sphere 5c that can be inserted and removed and a bit 5e having a plurality of grooves 5d in which the sphere 5c is accommodated are prepared, and the position of the bit 5e depends on the position of the groove 5d that accommodates the sphere 5c. A mechanism that can change the mounting position in the bit connection hole (not shown),
(B) As shown in FIG. 8 (b), a bit 5g having a screw 5f cut and a gear 5h adapted to the screw 5f are prepared, and by rotating the gear 5h, the bit 5g is rotated and the axial direction A mechanism that can change the position and change the attachment position of the bit 5g to the bit connection hole (not shown), or
(C) A mechanism that can control the movement / fixation of the bit in the axial direction by an externally attached screw to change the attachment position of the bit to the bit connection hole can be used.
Among these, it is preferable to employ (a) or (b).

  Here, it is preferable to use a material made of a lightweight metal material such as an aluminum alloy as the material of the main body 1. However, when the steel bit 5a is press-fitted into the bit connection hole 5b of the aluminum alloy main body 1, the bit 5a being used is not rattled and removed from the tip of the bit 5a. It is preferable to use a knurled pattern engraved on all or part of the surface up to the center. The knurled bit 5a can be obtained, for example, by using a round shaft as a material and engraving a knurled pattern from the tip to the center, and then processing the rear end in a bit shape. Is preferred.

  The cutter manufacturing method used in the cable coating stripping tool of the present invention is not particularly limited and can be manufactured by subjecting a cube or angle-shaped material to precise cutting, but (1) drilling from a steel plate. A step of obtaining a cutter material by pressing, (2) a step of barrel-polishing the cutter material, (3) a step of bending the cutter material into a substantially L shape by pressing, (4) of the folded cutter material It is preferable to manufacture by a step of forming a blade portion by grinding on the inner side of one flange surface and (5) a step of forming a cutting blade portion by polishing on the outer side of the other surface.

  In the step (1), it is preferable to form a hole for inserting the fastener together with the outer shape of the cutter. In this punching press work, burrs may be generated at the edges of the material during pressing, and cracking may occur when bending is performed with the burrs remaining. Therefore, it is important to carry out the barrel polishing process (2). The cutter material that has been subjected to barrel polishing is bent into an approximately L shape by pressing, and a blade portion is formed by grinding on the inside of one of the flange surfaces, and is cut by polishing on the outside of the other surface. A blade portion is formed. After the step (3), the outer surface of one flange surface of the substantially L-shaped cutter material is positioned by cutting, and then the blade surface of the scissors blade portion is formed by grinding on the inner surface of the flange surface. It is good to do. Moreover, it is preferable that the blade surface of the scissors blade portion formed by machining is further polished.

  As described above, the cutter used in the cable coating stripping tool of the present invention is made of an inexpensive plate material, and can be manufactured by a normal processing process instead of a precise cutting process. can do. In particular, in a cable covering stripping tool, since the cutter is a consumable item, it is important to reduce its price.

  According to the cable coating stripping tool according to the present invention, clogging of chips of the coating layer can be prevented. As a result, the opportunity to interrupt the work to remove chips and the opportunity to break the connection to the rotary tool can be greatly reduced, and the efficiency of the cable sheath stripping work is greatly improved. be able to. And if it comes to the preferable aspect of this invention, it will become possible to manufacture the cutter for cable coating stripping tools cheaply.
