(5)如上述(4)记载的覆皮剥除方法，在所述第2切口工序后，具有以下的工序：(5) The coating peeling method described in the above (4), after the second incision step, has the following steps:
内剥离工序，利用内剥离部将所述绝缘覆皮从导体分离，所述内剥离部在所述覆皮切断部所进行的所述绝缘覆皮的切断完了时抵接于所述电线的所述导体，并嵌入到由所述覆皮切断部切断后的所述绝缘覆皮和所述导体之间；以及In the inner peeling step, the insulation coating is separated from the conductor by an inner peeling portion that abuts against all of the electric wires when cutting of the insulation coating by the coating cutting portion is completed. the conductor, and embedded between the insulating sheath cut by the sheath cutting portion and the conductor; and
导体按压工序，利用导体按压部防止所述覆皮切断部吃入到所述导体，所述导体按压部在所述覆皮切断部所进行的所述绝缘覆皮的切断完了时抵接于所述导体，在该状态下，在所述电线被拉向所述覆皮切断部的背面侧时与所述导体滑动接触。In the conductor pressing step, the conductor pressing part is used to prevent the conductor from being bitten by the covering cutting part, and the conductor pressing part abuts against the conductor when the cutting of the insulating covering by the covering cutting part is completed. In this state, the electric wire is in sliding contact with the conductor when the electric wire is pulled toward the back side of the covering cut portion.
根据上述(1)的构成，电线的绝缘覆皮的剥除所使用的刀件是单一部件即可。而且，在该覆皮剥除刀的情况下，例如当为了将被保持为绷紧状态的电线收容到电线嵌入槽，而该使覆皮剥除刀成为后倾姿态并沿着后倾的斜度压抵在电线时，一对第1切入部吃入到电线的两侧的绝缘覆皮，能够在电线的两侧的绝缘覆皮上切出切口。而且，当进一步使覆皮剥除刀压入到电线时，一对第2切入部进入由一对第1切入部形成的切口，将切口压开。其结果是，即使在由一对第1切入部形成切口没有深达电线的导体的状态下，也能够利用一对第2切入部的进入而将切口压开，将绝缘覆皮切离成导体露出的状态。而且，再进一步使覆皮剥除刀压入到电线时，通过覆皮切断部所进行的绝缘覆皮的切断，从而能够得到以与电线的两侧的切口相连的形状将绝缘覆皮切断的状态。因此，能够通过将电线继续拉向覆皮切断部的背面侧而使切断后的绝缘覆皮剥起，从而将绝缘覆皮从电线的导体剥除。According to the configuration of (1) above, the blade used for peeling off the insulation coating of the electric wire may be a single part. In addition, in the case of this coating stripping knife, for example, in order to accommodate the electric wire held in a tense state in the electric wire insertion groove, the coating stripping knife is brought into a rearwardly inclined posture and pressed along the backward slope. When abutting against the electric wire, the pair of first cut-in parts eat into the insulating coating on both sides of the electric wire, and can cut out the incision on the insulating covering on both sides of the electric wire. Furthermore, when the sheathing stripping knife is pressed into the electric wire, the pair of second incisions enters the slit formed by the pair of first incisions, and presses the slit apart. As a result, even in a state where the incision formed by the pair of first incisions does not reach as far as the conductor of the electric wire, the incision can be pressed open by the entry of the pair of second incisions, and the insulating coating can be cut into conductors. exposed state. Furthermore, when the coating stripping knife is pressed into the electric wire, the insulation coating is cut by the coating cutting part, so that the state where the insulation coating is cut in a shape connected to the cutouts on both sides of the electric wire can be obtained. . Therefore, the insulating coating can be peeled off from the conductor of the electric wire by continuing to pull the electric wire toward the back side of the coating cut portion to peel off the cut insulating coating.
即，根据上述(1)的构成，电线的绝缘覆皮的剥除所需要的操作只需要以预定的后倾姿态将覆皮剥除刀送入到电线上的覆皮剥除刀的平行移动操作、和以覆皮剥除刀吃入到绝缘覆皮的状态将电线向覆皮切断部的背面侧拔出的电线移动操作即可，绝缘覆皮的剥除所需要的操作变得简单。That is, according to the configuration of (1) above, the operation required for stripping the insulation coating of the electric wire only requires the parallel movement operation of the coating stripping knife sent to the electric wire with a predetermined backward tilt posture, The operation required for stripping the insulation coating is simplified by simply moving the wire to pull out the wire to the back side of the coating cutting part with the coating stripping knife biting into the insulation coating.
因此，能够使支承覆皮剥除刀、电线的机构单纯化，降低绝缘覆皮的剥除处理的成本。Therefore, the mechanism for supporting the stripping knife and the electric wire can be simplified, and the cost of stripping the insulating coating can be reduced.
根据上述(2)的构成，在以与电线的两侧的切口相连的形状将绝缘覆皮切断的状态下，电线被拉向覆皮切断部的背面侧时，内剥离部嵌入到由覆皮切断部切断后的绝缘覆皮与导体之间，从而将绝缘覆皮从电线的导体剥起。According to the configuration of (2) above, when the wire is pulled to the back side of the cut part of the coating in the state where the insulating coating is cut in a shape connected to the cutouts on both sides of the wire, the inner peeling part is embedded in the insulation coating formed by the coating. The cutting part cuts between the insulating coating and the conductor, thereby peeling the insulating coating from the conductor of the electric wire.
即，根据上述(2)的构成，在覆皮切断部进行绝缘覆皮的切断时，与内剥离部的终端连续的导体按压部抵接在电线的导体。在电线被拉向覆皮切断部的背面侧时，该导体按压部成为电线的导体进行滑动的滑动面，从而防止覆皮切断部吃入到电线的导体。That is, according to the configuration of (2) above, when the insulation coating is cut by the coating cutting portion, the conductor pressing portion continuous to the end of the inner peeling portion abuts against the conductor of the electric wire. When the electric wire is pulled toward the back side of the sheath cutting part, the conductor pressing part becomes a sliding surface on which the conductor of the electric wire slides, thereby preventing the sheath cutting part from eating the conductor of the electric wire.
因此，能够防止在绝缘覆皮的剥除时伤及电线的导体。Therefore, it is possible to prevent the conductor of the electric wire from being damaged when the insulation coating is peeled off.
根据上述(3)的构成，一对第1切入部相对于电线嵌入槽的中心线对称地配置。因此，被压入到这些一对第1切入部间的电线，通过一对第1切入部所带来的定心作用，被保持在一对第1切入部的中间，绝缘覆皮被切口。According to the structure of (3) above, a pair of 1st cut-in part is arrange|positioned symmetrically with respect to the centerline of an electric wire insertion groove. Therefore, the electric wire pressed between the pair of first cutouts is held in the middle of the pair of first cutouts by the centering action of the pair of first cutouts, and the insulating coating is notched.
因此，能够防止因电线的偏心而使仅电线的一侧的切口较深，从而伤及电线的导体，能够提高绝缘覆皮的切口精度。Therefore, it is possible to prevent damage to the conductor of the electric wire due to the eccentricity of the electric wire from making the cut deep only on one side of the electric wire, and to improve the cutting precision of the insulating coating.
根据上述(4)的构成，通过依次执行使电线嵌入到电线嵌入槽的工序、第1切口工序、第2切口工序、以及覆皮切断工序，容易得到绝缘覆皮被切断的状态的电线。因此，通过将电线继续拉向覆皮切断部的背面侧，使被切断后的绝缘覆皮剥起，从而能够将绝缘覆皮从电线的导体剥除。According to the configuration of (4) above, by sequentially performing the step of fitting the electric wire into the electric wire fitting groove, the first notching step, the second notching step, and the coating cutting step, it is easy to obtain the electric wire in a state where the insulating coating is cut. Therefore, the insulating coating can be peeled off from the conductor of the electric wire by continuing to pull the electric wire toward the back side of the coating cut portion to peel off the cut insulating coating.
根据上述(5)的构成，通过在第2切口工序后依次执行内剥离工序、以及导体按压工序，能够防止覆皮切断部吃入到电线的导体，防止伤及电线的导体。According to the configuration of (5) above, by sequentially performing the inner peeling step and the conductor pressing step after the second notching step, it is possible to prevent the covering cutting portion from eating the conductor of the electric wire and preventing the conductor of the electric wire from being damaged.

具体实施方式detailed description
以下，参照附图对本发明的覆皮剥除刀及覆皮剥除方法的最优实施方式进行详细说明。Hereinafter, best embodiments of the peeling blade and the peeling method of the present invention will be described in detail with reference to the accompanying drawings.
如图1～图8所示，本发明的一实施方式的覆皮剥除刀10被用于图6所示的圆型电线20的绝缘覆皮21的剥除。As shown in FIGS. 1 to 8 , a sheath stripping blade 10 according to an embodiment of the present invention is used for stripping an insulating sheath 21 of a round electric wire 20 shown in FIG. 6 .
圆型电线20是用绝缘覆皮21将断面圆形的电线导体(导体)22的周围覆盖的电线。绝缘覆皮21以大致均等的厚度形成。The round electric wire 20 is an electric wire in which an electric wire conductor (conductor) 22 having a circular cross section is covered with an insulating sheath 21 . The insulating coating 21 is formed with a substantially uniform thickness.
本实施方式的覆皮剥除刀10包括：板状的主体11；在该主体11的一边缘11a开口而形成的电线嵌入槽12；在该电线嵌入槽12的开口12a侧，在对置的一对侧缘部形成的一对倾斜刃(第1切入部)13；从这些一对倾斜刃13的终端(与开口12a侧相反的进深侧端)延伸到电线嵌入槽12的进深侧的一对平行刃(第2切入部)14；将这些一对平行刃14的终端(与开口12a侧相反的进深侧端)连接的圆弧形刃(覆皮切断部)15；在该圆弧形刃15的背面侧与其相连设置的内剥离刃(内剥离部)16；以及与该内剥离刃16的终端(与开口12a侧相反的进深侧端)连续地形成的导体按压面(导体按压部)17。The peeling knife 10 of the present embodiment includes: a plate-shaped main body 11; an electric wire insertion groove 12 formed by opening an edge 11a of the main body 11; A pair of inclined blades (first cuts) 13 formed on the side edges; a pair extending from the terminal end of the pair of inclined blades 13 (the end on the opposite side to the side of the opening 12a) to the deep side of the electric wire insertion groove 12 Parallel blades (second incisions) 14; arcuate blades (coating cutting portions) 15 connecting terminal ends of the pair of parallel blades 14 (ends opposite to the opening 12a side); 15, the inner stripping blade (inner stripping portion) 16 which is provided continuously therewith; and the conductor pressing surface (conductor pressing portion) formed continuously with the terminal end (the opposite end of the opening 12a side) of the inner stripping blade 16 17.
如图2所示，在主体11的背面111，局部形成有朝向该主体11的一边缘11a板厚渐渐变小的倾斜面112。As shown in FIG. 2 , on the back surface 111 of the main body 11 , an inclined surface 112 is partially formed in which the thickness gradually decreases toward an edge 11 a of the main body 11 .
电线嵌入槽12是在主体11的具有倾斜面112的部位的一边缘11a开口而形成的。该电线嵌入槽12是能够使圆型电线20嵌入的槽。该电线嵌入槽12形成有一对倾斜刃13、一对平行刃14、圆弧形刃15、内剥离刃16、和导体按压面17。The wire insertion groove 12 is formed by opening an edge 11 a of a portion of the main body 11 having the inclined surface 112 . The electric wire insertion groove 12 is a groove into which the round electric wire 20 can be inserted. The wire insertion groove 12 is formed with a pair of inclined blades 13 , a pair of parallel blades 14 , an arc-shaped blade 15 , an inner peeling blade 16 , and a conductor pressing surface 17 .
一对倾斜刃13如图5所示，形成有锐利的刃部13a，该刃部13a呈朝向电线嵌入槽12的开口侧而渐渐槽宽扩大的倾斜线状。一对倾斜刃13如图5所示，相对于电线嵌入槽12的中心线O1对称地形成有刃部13a。As shown in FIG. 5 , the pair of inclined blades 13 is formed with a sharp blade portion 13 a in the shape of an inclined line whose groove width gradually expands toward the opening side of the electric wire insertion groove 12 . As shown in FIG. 5 , the pair of inclined blades 13 have blade portions 13 a formed symmetrically with respect to the center line O1 of the electric wire insertion groove 12 .
另外，在这些一对倾斜刃13的终端处，刃部13a间的离开间隔w1被设定得比圆型电线20的电线导体22的外径d(参照图6)稍大。例如，在电线导体22的外径d为0.75mm的情况下，在一对倾斜刃13的终端处刃部13a间的离开间隔w1被设定为0.95mm。In addition, at the ends of the pair of inclined blades 13, the distance w1 between the blade portions 13a is set slightly larger than the outer diameter d of the wire conductor 22 of the round wire 20 (see FIG. 6). For example, in the case where the outer diameter d of the wire conductor 22 is 0.75 mm, the distance w1 between the blade portions 13 a at the terminal ends of the pair of inclined blades 13 is set to 0.95 mm.
另外，在一对倾斜刃13的始端(开口12a侧的槽近前侧端)处，刃部13a间的离开间隔w2被设定为比圆型电线20的绝缘覆皮21的外径D(参照图6)大。In addition, at the starting end of the pair of inclined blades 13 (the end near the groove on the side of the opening 12a), the distance w2 between the blade portions 13a is set to be smaller than the outer diameter D of the insulating coating 21 of the round electric wire 20 (refer to Figure 6) Large.
另外，在一对倾斜刃13的始端形成有一对引导刃18。一对引导刃18不是将绝缘覆皮21切断的锐利的刃，而是在圆型电线20触碰到电线嵌入槽12的角时，起到将该圆型电线20引导到电线嵌入槽12内的引导功能。该引导刃18被设定为倾斜比刃部13a的倾斜缓和。具体而言，当设引导刃18与垂线V1的夹角为θ1时，设定θ1＝55度左右的大小。In addition, a pair of guide blades 18 are formed at the starting ends of the pair of inclined blades 13 . The pair of guide blades 18 are not sharp blades for cutting the insulating sheath 21, but guide the round wire 20 into the wire insertion groove 12 when the round wire 20 touches the corner of the wire insertion groove 12. boot function. The guide blade 18 is set so that its inclination is gentler than the inclination of the blade portion 13a. Specifically, when the angle between the guide blade 18 and the vertical line V1 is defined as θ1, the value of θ1 is set to be about 55 degrees.
以上说明的一对倾斜刃13，在嵌入到电线嵌入槽12的圆型电线20的两侧部的绝缘覆皮21上切出切口。The pair of inclined blades 13 described above cut out the insulating coating 21 on both sides of the round electric wire 20 fitted into the electric wire insertion groove 12 .
一对平行刃14如图5所示，从位于电线嵌入槽12的进深侧的一对倾斜刃13的终端与中心线O1平行地延伸到电线嵌入槽12的进深侧。因此，一对平行刃14间的离开距离为w1。这些一对平行刃14以不切断圆型电线20的绝缘覆皮21的程度使刃部14a圆钝。这些一对平行刃14在圆型电线20被压入到电线嵌入槽12时，通过进入倾斜刃13所形成的切口而将该切口压开。The pair of parallel blades 14 extends from the end of the pair of inclined blades 13 on the deeper side of the wire insertion groove 12 in parallel to the central line O1 to the deeper side of the wire insertion groove 12 as shown in FIG. 5 . Therefore, the separation distance between the pair of parallel blades 14 is w1. These pair of parallel blades 14 make the blade portion 14 a blunt to such an extent that the insulation coating 21 of the round electric wire 20 is not cut. The pair of parallel blades 14 presses apart the slit formed by the inclined blade 13 when the round electric wire 20 is pressed into the electric wire insertion groove 12 .
圆弧形刃15呈大致圆弧状形成有刃部15a，该刃部15a将位于电线嵌入槽12的进深侧的一对平行刃14的终端间连接。该圆弧形刃15通过压抵在对置的圆型电线20的上部，从而以与圆型电线20的两侧的切口相连的半圆周状，将绝缘覆皮21切断。The arc-shaped blade 15 has a substantially arc-shaped blade portion 15 a that connects terminals of a pair of parallel blades 14 located on the deep side of the electric wire insertion groove 12 . The arc-shaped blade 15 is pressed against the upper portion of the opposing round electric wire 20 to cut the insulating coating 21 in a semicircular shape connected to the notches on both sides of the round electric wire 20 .
内剥离刃16如图4及图6所示，在圆弧形刃15的背面侧与相连设置。该内剥离刃16如图7所示，被形成为：以预定的倾斜角θ2从圆弧形刃15在主体11的板厚方向延伸。在此，倾斜角θ2是相对于剥除处理的圆型电线20的向电线嵌入槽12的插通方向(图7及图8中箭头X1方向)的夹角。在本实施方式的情况下，倾斜角θ2优选设定为13度左右。As shown in Figure 4 and Figure 6, the inner peeling blade 16 is arranged on the back side of the arc-shaped blade 15 in a row. As shown in FIG. 7 , the inner peeling blade 16 is formed to extend from the arc-shaped blade 15 in the thickness direction of the main body 11 at a predetermined inclination angle θ2. Here, the inclination angle θ2 is an angle with respect to the insertion direction (arrow X1 direction in FIGS. 7 and 8 ) of the stripped round electric wire 20 into the electric wire fitting groove 12 . In the case of the present embodiment, the inclination angle θ2 is preferably set to about 13 degrees.
在沿着图6的箭头Y1方向覆皮剥除刀10被压抵于圆型电线20，而由一对倾斜刃13及圆弧形刃15所进行的绝缘覆皮21的切断完了时，本实施方式的内剥离刃16抵接在电线导体22。在该状态下，如图8中箭头X1所示，圆型电线20被沿着其中心轴线拉向圆弧形刃15的背面侧时，内剥离刃16嵌入到由圆弧形刃15切断的绝缘覆皮21和电线导体22之间，该内剥离刃16将绝缘覆皮21从电线导体22剥起。When the sheath stripping knife 10 is pressed against the round electric wire 20 along the arrow Y1 direction of FIG. The inner stripping blade 16 of the form abuts against the electric wire conductor 22 . In this state, as shown by arrow X1 in FIG. Between the insulation coating 21 and the wire conductor 22 , the inner stripping blade 16 peels the insulation coating 21 from the wire conductor 22 .
导体按压面17如图4及图6所示，与内剥离刃16的终端连续地形成。该导体按压面17在圆弧形刃15所进行的绝缘覆皮21的切断完了时抵接在电线导体22，在该状态下圆型电线20被沿着其中心轴线拉向圆弧形刃15的背面侧时，如图8所示，成为电线导体22进行滑动的滑动面，从而防止圆弧形刃15吃入到电线导体22。The conductor pressing surface 17 is formed continuously with the terminal end of the inner peeling blade 16 as shown in FIGS. 4 and 6 . The conductor pressing surface 17 abuts against the electric wire conductor 22 when the cutting of the insulating coating 21 by the arcuate blade 15 is completed, and in this state the round electric wire 20 is pulled toward the arcuate blade 15 along its central axis. As shown in FIG. 8 , it becomes the sliding surface on which the electric wire conductor 22 slides, thereby preventing the arc-shaped blade 15 from being bitten into the electric wire conductor 22 .
接下来，说明一实施方式的覆皮剥除刀10所进行的绝缘覆皮的剥除处理。Next, the stripping process of the insulating coating performed by the coating stripping blade 10 according to one embodiment will be described.
首先，如图6所示，使剥除对象的圆型电线20插通圆型电线20插通自如的圆筒状的电线引导件30，保持绷紧状态。电线引导件30在覆皮剥除刀10所进行的剥除处理时限制圆型电线20的向径向的移动。First, as shown in FIG. 6 , the round electric wire 20 to be stripped is inserted through the cylindrical electric wire guide 30 through which the round electric wire 20 can be inserted freely, and a tensioned state is maintained. The electric wire guide 30 restricts the movement of the round electric wire 20 in the radial direction during the stripping process performed by the stripping blade 10 .
接下来，在接近电线引导件30的位置，覆皮剥除刀10如图6所示那样，被保持在以倾斜角度α后倾的状态，并被以该倾斜状态从图的箭头Y1方向压抵在圆型电线20，将圆型电线20压入到电线嵌入槽12内。覆皮剥除刀10的倾斜角度α是与圆型电线20的中心轴线正交的垂直面V2和覆皮剥除刀10的表面10a(与倾斜面112相反侧的面)的夹角。Next, at a position close to the electric wire guide 30, as shown in FIG. 6, the sheath stripping blade 10 is held in a state inclined backward at an inclination angle α, and is pressed against in the direction of arrow Y1 in the figure in this inclined state. In the round electric wire 20 , the round electric wire 20 is press-fitted into the electric wire fitting groove 12 . The inclination angle α of the stripping blade 10 is the angle between the vertical plane V2 perpendicular to the central axis of the round electric wire 20 and the surface 10 a (the surface opposite to the inclined surface 112 ) of the stripping blade 10 .
于是，利用覆皮剥除刀10的倾斜刃13、平行刃14和圆弧形刃15能够得到在圆型电线20的上部侧的绝缘覆皮21上形成有半圆周状的切口的状态。此时优选：如图8所示，覆皮剥除刀10的末端部与电线引导件30之间的离开距离L保持在0.1mm左右。在该状态下，覆皮剥除刀10的位置保持着固定，如图8中箭头X1所示，圆型电线20被拉向圆弧形刃15的背面侧，切出有半圆周状的切口的绝缘覆皮21被内剥离刃16剥起。因此，通过将圆型电线20向图8的箭头X1方向拉出预定长度，从而对于圆型电线20，将绝缘覆皮21只剥除预定长度的长度量。Then, by the inclined blade 13 , the parallel blade 14 and the arc-shaped blade 15 of the coating stripping knife 10 , a semicircumferential notch can be formed in the insulating coating 21 on the upper side of the round electric wire 20 . In this case, it is preferable to keep the distance L between the tip of the peeling blade 10 and the wire guide 30 at about 0.1 mm as shown in FIG. 8 . In this state, the position of the peeling knife 10 remains fixed. As shown by arrow X1 in FIG. The insulation coating 21 is peeled off by the inner peeling blade 16 . Therefore, by pulling out the round electric wire 20 by a predetermined length in the arrow X1 direction of FIG. 8 , the insulating coating 21 is stripped off by a predetermined length from the round electric wire 20 .
此外，在图8所示的剥除处理中，电线导体22在导体按压面17上滑动，利用该导体按压面17防止浮动到圆弧形刃15侧。因此，防止在绝缘覆皮21的剥除处理中圆弧形刃15接触到电线导体22，能够防止电线导体22的损伤。In addition, in the stripping process shown in FIG. 8 , the electric wire conductor 22 slides on the conductor pressing surface 17 , and the conductor pressing surface 17 prevents it from floating to the arcuate blade 15 side. Therefore, the arc-shaped blade 15 is prevented from coming into contact with the electric wire conductor 22 during the peeling process of the insulating coating 21, and damage to the electric wire conductor 22 can be prevented.
在以上所说明的一实施方式的覆皮剥除刀10的情况下，圆型电线20的绝缘覆皮21的剥除中所使用的刀件是单一部件即可。因此，与使用多个刀件的情况相比，能够使刀件的支持机构单纯化。In the case of the sheath stripping blade 10 of one embodiment described above, the blade used for stripping the insulating sheath 21 of the round electric wire 20 may be a single member. Therefore, compared with the case where a plurality of blades are used, the support mechanism of the blade can be simplified.
而且，在该覆皮剥除刀10的情况下，能够：例如，当为了将保持为绷紧状态的圆型电线20收容到电线嵌入槽12，而使该覆皮剥除刀10成为后倾姿态并沿着后倾的倾斜角度α压抵在圆型电线20时，一对倾斜刃13吃入到圆型电线20的两侧的绝缘覆皮21，在圆型电线20的两侧的绝缘覆皮21上切出切口。Furthermore, in the case of the sheathing stripping knife 10, for example, in order to accommodate the round electric wire 20 maintained in a taut state in the electric wire insertion groove 12, the sheathing stripping knife 10 can be made into a backward posture and When pressing against the round electric wire 20 along the inclined angle α of the backward inclination, a pair of inclined blades 13 eat into the insulating coating 21 on both sides of the round electric wire 20, and the insulating coating on both sides of the round electric wire 20 21 cut out the incision.
而且，当进一步使覆皮剥除刀10压入到圆型电线20时，一对平行刃14进入由一对倾斜刃13形成的切口，将切口压开。其结果是，能够在由一对倾斜刃13形成的切口没有深达电线22的导体的状态下，通过一对平行刃14的进入而将切口压开，将绝缘覆皮21切离成导体露出的状态。Further, when the sheath stripping knife 10 is pressed into the round electric wire 20, the pair of parallel blades 14 enters the cut formed by the pair of inclined blades 13, and presses the cut open. As a result, in the state where the incision formed by the pair of inclined blades 13 does not reach as deep as the conductor of the electric wire 22, the incision can be pressed open by the entry of the pair of parallel blades 14, and the insulating coating 21 can be cut away so that the conductor is exposed. status.
而且，再进一步使覆皮剥除刀10压入到圆型电线20时，通过圆弧形刃15所进行的绝缘覆皮21的切断，从而能够得到以与圆型电线20的两侧的切口相连的半圆周状将绝缘覆皮21切断的状态。而且，在该状态下，当如图8所示将圆型电线20拉向圆弧形刃15的背面侧时，内剥离刃16嵌入到由圆弧形刃15切断的绝缘覆皮21与电线导体22之间，将绝缘覆皮21从电线导体22剥起。And further, when the covering stripping knife 10 is pressed into the round electric wire 20, the cutting of the insulating covering 21 carried out by the arc-shaped blade 15 can be connected with the incisions on both sides of the round electric wire 20. A state in which the insulation coating 21 is cut in a semi-circumferential shape. And, in this state, when the round electric wire 20 is pulled toward the back side of the arcuate blade 15 as shown in FIG. Between the conductors 22, the insulating coating 21 is peeled off from the wire conductors 22.
即，用本实施方式的覆皮剥除刀10，圆型电线20的绝缘覆皮21的剥除所需要的操作只需以预定的后倾姿态将覆皮剥除刀10送入到圆型电线20上的覆皮剥除刀10的平行移动操作、和在覆皮剥除刀10的刃吃入到绝缘覆皮21状态下将圆型电线20向圆弧形刃15的背面侧拔出的电线移动操作即可，绝缘覆皮21的剥除所需要的操作变得简单。That is, with the sheath stripping knife 10 of the present embodiment, the operation required for stripping the insulating sheath 21 of the round electric wire 20 only needs to send the sheath stripping knife 10 to the round electric wire 20 with a predetermined backward posture. The parallel movement operation of the coating stripping knife 10 on the top, and the wire moving operation of pulling out the round electric wire 20 to the back side of the arc-shaped blade 15 under the condition that the blade of the coating stripping knife 10 is eaten into the insulating coating 21 That is, the operation required for peeling off the insulating coating 21 becomes simple.
因此，能够将支承覆皮剥除刀10、圆型电线20的机构单纯化，降低绝缘覆皮21的剥除处理的成本。Therefore, the mechanism for supporting the stripping blade 10 and the round electric wire 20 can be simplified, and the cost of stripping the insulating coating 21 can be reduced.
另外，在本实施方式的覆皮剥除刀10的情况下，圆弧形刃15所进行的绝缘覆皮21的切断时，如图8所示，与内剥离刃16的终端连续的导体按压面17抵接在电线导体22。在圆型电线20被向圆弧形刃15的背面侧拔出时，该导体按压面17成为电线导体22进行滑动的滑动面，从而防止圆弧形刃15吃入到电线导体22。In addition, in the case of the coating stripping knife 10 of the present embodiment, when the insulating coating 21 is cut by the arc-shaped blade 15, as shown in FIG. 17 abuts against the wire conductor 22. When the round electric wire 20 is pulled out toward the back side of the arc-shaped blade 15, the conductor pressing surface 17 becomes a sliding surface on which the wire conductor 22 slides, thereby preventing the arc-shaped blade 15 from being bitten into the wire conductor 22.
因此，能够防止在绝缘覆皮21的剥除时伤及电线导体22。Therefore, it is possible to prevent the electric wire conductor 22 from being damaged when the insulating coating 21 is peeled off.
另外，在本实施方式的覆皮剥除刀10的情况下，一对倾斜刃13相对于电线嵌入槽12的中心线O1对称地配置。因此，被压入到这些一对倾斜刃13间的圆型电线20由于一对倾斜刃13所带来的定心作用，而被保持在一对倾斜刃13的中间，绝缘覆皮21被切口。In addition, in the case of the sheath stripping knife 10 of this embodiment, the pair of inclined blades 13 are arranged symmetrically with respect to the center line O1 of the electric wire insertion groove 12 . Therefore, the round electric wire 20 pressed between the pair of inclined blades 13 is held in the middle of the pair of inclined blades 13 due to the centering effect of the pair of inclined blades 13, and the insulating coating 21 is notched. .
因此，能够防止因圆型电线20的偏心而使仅圆型电线20的一侧的切口较深从而伤及电线导体22，能够提高绝缘覆皮21的切口精度。Therefore, it is possible to prevent the wire conductor 22 from being damaged due to the eccentricity of the round wire 20 due to the eccentricity of the round wire 20 due to the deep cut only on one side, and to improve the cutting accuracy of the insulating coating 21 .
另外，在本实施方式的覆皮剥除刀10的情况下，由于平行刃14的刃部圆钝，所以能够确实防止平行刃14与电线导体22接触而伤及电线导体22。In addition, in the case of the coating stripping knife 10 of this embodiment, since the blade portion of the parallel blade 14 is blunt, it is possible to reliably prevent the parallel blade 14 from coming into contact with the wire conductor 22 to damage the wire conductor 22 .
此外，本发明不限定于上述实施方式，能够适当进行变形、改良等。另外，上述实施方式中的各构成要素的材质、形状、尺寸、数量、配置场所等只要能够达成本发明则是任意的，没有限定。In addition, this invention is not limited to the said embodiment, Deformation, improvement, etc. are possible suitably. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-mentioned embodiment are arbitrary as long as the present invention can be achieved, and are not limited.
例如，第1切入部不限于上述倾斜刃13，也可以是円弧状的刃。For example, the first cutting portion is not limited to the above-mentioned inclined blade 13, and may be an arc-shaped blade.
另外，第2切入部不限于上述平行刃14，也可以是V字形状。In addition, the second notch is not limited to the above-mentioned parallel blades 14, and may be V-shaped.
