[Detailed description of the invention] (Field of industrial application) The present invention relates to a cutting blade mechanism for an automatic sheathing/cutting device for covered wires that can simultaneously strip and cut multiple coated wires used in various electrical products, etc. It is.

(Prior Art) In recent years, with the diversification and increase in demand for electrical and electronic products, various covered electric wires have been manufactured, sold, and used. In recent years, in order to more efficiently strip and cut covered wires connected to electrical and electronic components, for example, a small automatic wire stripping and cutting device as shown in Figure 4 has been used to cut a single coated wire. The covered wire is continuously stripped and cut to the desired size.

The cutting blade for stripping and cutting coated wires attached to this device consists of a fixed blade 101 with a V-shaped cutting edge and a movable blade 102, as shown in Fig. 5, and these two blades are capable of cutting. The blades are attached to the mounting base 103 with the cutting edges facing each other. Mounting stand 10
3 is provided so as to protrude outward from the peeling/cutting device as shown in the figure, and the movable blade 102 is connected to an operating mechanism provided inside the device, so that the fixed blade 101 and the movable blade 102 engage with each other. It's like this.

When stripping and cutting the coated wire, one coated wire is attached to each roller 104...
... to the cutting edge side, and each of these rollers 104
The movable blade 102 is rotated in forward and reverse directions, and the movement of the movable blade 102 is controlled to strip and cut the covered wire.

In addition, when stripping and cutting so-called flat cables, which conventionally are made by arranging many electric wires in parallel and integrally forming PVC, a flat fixed blade and a movable blade are used, and the movable blade is moved up and down. The blade was then engaged with the fixed blade and the flat cable was sandwiched between them.

(Problem that the invention aims to solve) However, with the former V-shaped cutting blade installed in automatic wire sheathing/cutting equipment, due to its structure, it is only possible to process one wire at a time, and a large amount of sheathing is required. When it is desired to strip or cut electric wires, this cutting blade had problems in terms of work efficiency.

In addition, the latter flat cutting blade for stripping and cutting the flat cable had a structure in which the movable blade was operated vertically to press the flat cable from above to strip and cut the cable. One drawback was that the electric wires inside the cable could be crushed by the pressure of the movable blade.

The present invention was devised in view of these points, and its purpose is to attach it to the above-mentioned ready-made automatic insulated wire stripping/cutting device to crush multiple insulated wires at the same time. To provide a cutting blade mechanism of an automatic peeling and cutting device for coated electric wires, which can quickly perform peeling and cutting processing without causing unnecessary peeling and cutting.

(Means for Solving the Problems) Therefore, in order to effectively achieve the above object, the present invention has the following configuration. That is, an interlocking cutting blade is attached to the outside of the automatic sheathing/cutting device for covered electric wires and is connected to an operating mechanism installed inside the device to enable stripping/cutting of various covered electric wires. Inside the cutting blade holding case, long and narrow cutting blades are arranged in parallel at predetermined intervals via swinging rods pivotally connected to both ends, and one end of one of the cutting blades is extended so that the end is connected to the A number of cutting blade recesses are formed at predetermined intervals on the opposing cutting edges of each of the cutting blades so that the cutting blades disposed in parallel can be connected to each other in an oblique vertical direction by the operation of the working mechanism. The structure is such that the recesses are close to each other and engage with each other.

(Function) A plurality of wires are transferred to the cutting blade side of the cutting blade holding case protruding from the automatic insulated wire stripping/cutting device by an insulated wire feeding mechanism separately attached to the insulated wire automatic stripping/cutting device. A plurality of coated wires are simultaneously stripped or cut by the operation of the cutting blade.
That is, each covered wire is positioned in the cutting edge recess of each blade in the case by the covered wire feeding mechanism.

Each coated wire located in this way is automatically stripped and
Due to the operation of the operating mechanism of the cutting device, the cutting blade connected to the operating mechanism and arranged parallel to the other cutting blades moves, and the blade is moved through each swinging rod pivotally connected to the cutting blade. Each cutting blade approaches from an oblique direction, and each coated wire is cut by the engagement of the cutting blade recesses of the opposing cutting blades. At this time, the cutting blade recesses of the opposing cutting blades also approach each other diagonally and cut into the insulated wire in a gradual sliding motion, so each insulated wire is cut smoothly without being crushed like in the conventional method. be done.

In addition, when stripping the coated wire, each coated wire is moved back and forth using a coated wire feeding mechanism other than the present invention, and the cutting blade is controlled by the operating mechanism to cut the coated wire to the desired size. Strip the ends of the wires. At this time, as in the case of cutting above, the recesses of the opposing cutting blades approach each other from an oblique direction, and the recesses of the cutting blades slide to cut into the sheathing of the insulated wire, resulting in a clean peeling of the cut end. can be processed.

(Example) Hereinafter, an example of the present invention will be described based on FIGS. 1 to 3.

In the figure, 1 is an automatic sheathing/cutting device for the covered electric wire, 2 is a cutting blade mechanism according to the present invention, and 3 is a cutting blade holding case which is a part of this cutting blade mechanism 2. It is attached to a predetermined position of the automatic peeling/cutting device 1 so as to protrude from the device 1. Inside the case 3, there is a cutting blade mechanism 2.
Two swinging rods 4, a movable blade 5, and a fixed blade 6 constituting the blade are respectively hinged and provided inside.

This movable blade 5 is connected to an operating mechanism (not shown) provided in the automatic sheathing/cutting device 1 for covered wire, and is also connected to a fixed blade 6 via both swinging rods 4 . The movable blade 5 is connected to the operating mechanism, and together with the fixed blade 6 via both swinging rods 4, can strip or cut a plurality of covered electric wires by cutting diagonally.

Therefore, to explain the cutting blade mechanism 2 of one embodiment of the present invention in more detail, the cutting blade holding case 3
As shown in the figure, the case 3 has a thin rectangular frame shape with an opening at the center.
A slender fixed blade 6 has a cutting edge facing upward and is attached to the case 3.
It is fixed with support pins 7 at both ends along the long sides. Moreover, the blade edge of the fixed blade 6 is formed with blade edge recesses 6a at predetermined intervals. This cutting edge recess 6a
1 and 2 are portions for stripping and cutting the coated wire together with a cutting edge concave portion 5a of the movable blade 5, which will be described later, and are each formed into a deformed V-shape as shown in the figure. Of course, the shape of the cutting edge recess is not limited to the above-mentioned shape, and may be freely formed into various shapes such as U-shape, V-shape, etc.

Also, like the fixed blade 6, the movable blade 5 is an elongated blade with the lower long side as the cutting edge, and when in operation, it cuts so as to face the respective cutting blade recesses 6a formed in the fixed blade 6. A blade recess 5a is formed. The movable blade 5 and the fixed blade 6 are hinged together by two swinging rods 4, 4 at both ends, and each hinge portion 8 is pivotally supported by a support pin 9. The support pin 9 that pivotally supports the movable blade 5 and both swinging rods 4 is attached to the case 3.
The movable blade 5 approaches the fixed blade 6 from an oblique direction by moving the support pin 9 through the long hole 10 formed in the upper inner surface of the blade. can mesh together.

Note that 11 is a cylindrical roller attached to the automatic sheathing/cutting device 1, and each roller 11
A plurality of grooves 12 are formed at predetermined intervals,
It is designed to be able to transport multiple covered wires. 1
3 is a covered electric wire guide plate.

Next, a case will be described in which a plurality of covered wires are processed using the covered wire automatic stripping/cutting device 1 equipped with the cutting blade mechanism 2 of the above embodiment.

A plurality of coated wires to be stripped and cut are respectively engaged with the grooves 12 of the roller 11, and are transferred to the cutting blade mechanism 2 side via the guide plate 13 by the rotation of the roller 11. The transferred covered wire is guided to each cutting blade recess 6a of the fixed blade 6 via the covered wire guide plate 13. When the covered wire reaches this position, the operating mechanism in the automatic covered wire stripping/cutting device 1 operates, and the movable blade 5 connected to the mechanism moves toward the tip of the case 3.

With this movement, the support pin 9 that pivotally supports the movable blade 5 and both swinging rods 4 is moved through the elongated hole 10 formed in the case 3.
The movable blade 5 moves toward the tip of the case 3, and the movable blade 5 approaches the fixed blade 6 from diagonally above. The cutting blade recess 5a of the movable blade 5 is the cutting blade recess 6a of the fixed blade 6.
Since the wires are engaged with each other and the covered wires are cut by sliding from the direction, it is possible to cut each covered wire without crushing the cut end.

In addition, when stripping the insulated wire, each insulated wire is moved back and forth by the roller 11, which is the insulated wire feeding mechanism, and the movable blade 5 and the swinging rod 4 are operated by the operating mechanism, and a plurality of Strip the ends of the covered wire.

Note that the present invention is not limited to the above embodiment, and instead of fixing the fixed blade 6 to the case 3, the fixed blade 6 is moved via the swinging rod 4 by the movement of the movable blade 5. and the movable blade 5 and fixed blade 6
It is also possible to approach from both sides so that the cutting edges engage with each other. Of course, in this case as well, the double blades 5 and 6 cut into the covered wire from diagonal directions.

In addition, as another embodiment (not shown), three cutting blades are provided in parallel at the upper, middle, and lower stages at a predetermined interval, and both ends of each blade (the upper or lower cutting blade is approximately in the middle) are connected to each other. It is pivoted to the respective swinging rods placed on both sides of the. The upper and lower cutting blades may be engaged with the interrupted cutting blade from an oblique direction, using both support pins that hold the interrupted cutting blade on the swing rod as fulcrums. In this case, the interrupted cutting edge is double-edged, and the cutting edge of each opposing cutting edge is formed with a cutting edge recess, as in the previous embodiment.

(Effects of the invention) As is clear from the above explanation, the invention has the following effects:
Since multiple coated wires can be stripped and cut at the same time, work efficiency can be further improved. Furthermore, since the cutting blade slides obliquely into each covered wire to be processed, there is no damage to the cut end or crushing of internal wires as in the conventional method.
