Description

The present invention relates to a twister auxiliary tool that is used together with a twister that twists a plurality of wires into a stranded wire and does not require an operator to grasp the wires in the twisting process.

As described in Non-Patent Documents 1 and 2, the twister is composed of a plurality of shafts 21, a rotating device 20a for rotating the shafts 21 on the same circle, and a clip 22, and a plurality of wire rods 30a are twisted. A twister 20 that makes one stranded wire 30 is known.

In the conventional twisting operation using the twister 20, the other end of the wire rod 30a, which is not gripped by the clip 22, is held by a person with a finger as shown in FIG. 1 (A). Therefore, in the conventional twisting work, there are problems that a person who grips the wire rod is required and that the twist pitch (width of one twist rotation) is not constant for each person who grips the wire rod. The reason why the twisting pitch is not constant is that the wire rod 30a is attracted to the twister 20 side by twisting, the tension of the wire rod 30a fluctuates, and it is different for each action because it is a habit of an operator and an artificial work.

Since the present invention has the above configuration, it has the following effects. That is, it is possible to provide a twister auxiliary tool that is used together with a twister that twists a plurality of wire rods into a twisted wire and does not require an operator to grasp the wire rod in the twisting process. As a result, the wire twisting work can be performed by one person, the number of workers can be reduced, and the work cost can be suppressed. Moreover, the pitch can be kept more constant.

It is explanatory drawing of a twisting machine and a stranded wire. It is a plane partial perspective view of the twister auxiliary tool of 1st Embodiment. FIG. 2A shows a state in which twisting has begun, and FIG. 2B shows a state in which twisting has progressed from (A). It is a top view of the twister auxiliary tool of 2nd Embodiment. FIG. 2A shows a state in which twisting has begun, and FIG. 2B shows a state in which twisting has progressed from (A).

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention is not limited to the following examples.

As shown in FIG. 2, the twister auxiliary tool 1 of the present invention includes a base 2, a guide 3, a slider 4, a stage 5, a clip 6, a rotary damper 7, a rack 8, and a constant load spring unit. It is composed of 9 and a floating prevention mechanism, and is used together with a twister for twisting a plurality of wire rods 30a around the twisted wire 30. During the twisting process, one end of the wire rod 30a is pinched.

The base 2 may be a plate-like body on which each member is placed, and it is more preferable that the base 2 is provided with rubber feet or the like as a non-slip on the bottom surface. Further, it is preferable that the stranded wire 30 and the wire rod 30a are heavy so as not to move due to the tension in the twisting process. On the other hand, the base 2 may be lightweight as long as it is provided with means for fixing the twister auxiliary tool 1 to the installation location, screws, pins, and the like.

The guide 3 is a rod-shaped body fixed and installed on the base 2 in parallel with the wire rod 30a and the stranded wire 30 direction.

The slider 4 is not particularly limited as long as it can slide along the guide 3. For example, a tubular object through which the guide 3 is inserted can be exemplified.

The stage 5 is connected to the slider 4, and during the twisting process, the wire 30a (twisted wire 30) becomes shorter as the twisting work progresses. Therefore, the tension of the wire 30a along with the slider 4 along with the slider 4 It is a platform that can move forward and move in the direction.

The clip 6 is attached to the stage 5 and grips the end portion of the wire rod 30a on the anti-twister side. The structure and function are not particularly limited as long as the wire rod 30a can be gripped against the tension of the wire rod 30a in the twisting process. Here, since the four wire rods 30a are twisted, the four clips 6 are fixed to the surface of the stage 5 on the wire rod 30a side.

The rotary damper 7 is fixed to the stage 5 by the housing 7a, includes a rotating shaft 7b, and further includes a pinion 7c, which is a gear, on the rotating shaft 7b. The rotary damper is generally distributed, and is generally a rotary damper that utilizes the braking force (braking force) generated by the viscous resistance of oil, and the operating speed can be relaxed. The faster the rotation, the higher the braking force. Here, it is used to prevent the stage 5 from suddenly returning when the twisted wire 30 is removed from the twister or the wire rod 30a is released from being held by the clip 6 after the twisting process is completed.

The rack 8 is fixed to the base 2 and meshes with the pinion 7c to form a rack and pinion gear, converts the linear motion of the stage 5 into a rotary motion, and is a rotary damper 7 provided with the pinion 7c, which is a rotary damper 7 of the stage 5. Buffer linear motion.

The constant load spring 9c is generally distributed, and the constant load spring unit 9 is, for example, a case 9a fixed to the base 2, a shaft 9b passed to the case 9a, and a drum rotatably installed on the shaft 9b. The constant load spring 9c wound around the drum is formed, and the pulled out constant load spring 9c is rewound. The constant load spring 9c is pulled out following the twisting progress (FIG. 3B), the tension on the wire rod 30a is maintained constant, and the twisting pitch is stabilized. When the wire rod 30a is unlocked by the clip 6, the constant load spring 9c is pulled back into the case 9a.

The floating prevention mechanism is not particularly limited as long as the pinion 7c can be prevented from floating from the rack 8. Here, the lid 10 is arranged above the rack 8 so that the pinion 7c does not rise from the rack 8.

In the twister auxiliary tool 1 thus formed, the stranded wire 30 is twisted with a constant tension by the constant load spring unit 9, the twist pitch can be controlled to be constant, and the rack 8 and the rotary damper 7 suddenly return the stage 5. Can be prevented. Since the width and thickness of the constant load spring 9c are various, a constant load spring 9c having a tension suitable for the wire rod 30a and the stranded wire 30 can be selected. A rotary damper having a desired torque can be selected accordingly.

As shown in FIG. 3, the twister assisting tool 11 of the present invention includes a base 2, left and right guides 3, 3, left and right sliders 14, 14, a stage 5, a clip 6, and a constant load spring unit 9. It is used together with a twister that twists a plurality of wire rods 30a into a twisted wire 30, and one end of the wire rod 30a is pinched during the twisting process. The same configuration as that of the first embodiment will be referred to therein, and the description thereof will be omitted here.

The left and right guides 3 and 3 are those in which the guide 3 of the first embodiment is fixed and installed on the left and right sides of the stage 5 in parallel with the wire rod 30a and the stranded wire 30 direction.

The left and right sliders 14 and 14 are slidable along the left and right guides 3 and 3 and have variable frictional resistance with the guides 3 and 3. For example, the frictional resistance can be made variable by making an incision in the side surface of the cylinder of the slider 14 and tightening the incised portion with a bolt, but the present invention is not limited to this.

The stage 5 is the same as that of the first embodiment, but is also connected to another slider 14, and is slidable in the stranded wire 30 direction by the left and right sliders 14, 14.

In the twister auxiliary tool 11 thus formed, the twisted wire 30 can be twisted with a constant tension by the constant load spring 9c, the twist pitch can be controlled to be constant, and the slider 14 can prevent the stage 5 from suddenly returning. can.
