用する配線線材切断用の電動ニツパに関するもの
である。[Detailed description of the invention] [Technical field] The present invention relates to an electric nipper (wire cutting tool).
In particular, the present invention relates to electric nippers for cutting wiring materials used in wiring work for communication equipment, computers, etc.

In recent years, most tools (for example, screwdrivers, drills, wire wrapping tools, etc.) have been electrified, contributing to improved efficiency in factory production lines (increased worker efficiency and reduced fatigue). All of these tools use electric motors as the driving power source, so they are easy to handle, and small and lightweight tools are also made, and are quite popular for home and cottage industrial use.

である。
By the way, it is difficult to electrify the nippers used, for example, when attaching parts to printed circuit boards and cutting the connections between those parts, so we have no choice but to use compressed air to drive the pistons that open and close the blades (air nippers). It is used. The reason why electrification is difficult is because the cutting work is done instantaneously, and it is difficult to cut gradually by rotating an electric motor, so so-called air nippers that use the instantaneous force of air pressure have been put into practical use. This is the translation.
エアニツパは特に弱電機工場で多く用いられ、
作業能率の向上に貢献しているが、動力源として
エアー配管，コンプレツサ等の付帯設備が必要で

体への送気用ホースの重量，柔軟性に多少問題が
あり、作業者の負担になつていた。 Air Nitzpa is especially used in light electrical factories.
Although it contributes to improving work efficiency, it requires ancillary equipment such as air piping and a compressor as a power source, which limits the handling location, and also has some impact on the weight and flexibility of the air supply hose to the Nitsupa main body. There were problems and it was a burden on the workers.
また、上記付帯設備が必要なことに加え、作業
時に圧縮空気による騒音が発生することにより、
家庭用，家内工業用に需要はあつても普及するま
でに至つていないのが現状である。 In addition to the need for the above-mentioned auxiliary equipment, the noise generated by compressed air during work causes
Although there is demand for household and cottage industrial use, the current situation is that it has not yet become widespread.

成のものが提案されている。 Therefore, as described in Utility Model Publication No. 46-2300, a rack is moved forward and backward by electromagnetic force, and a movable blade is opened and closed by a pinion that meshes with this rack and a cam that rotates integrally with this pinion. A configuration has been proposed that allows

業等には不適当である。 By the way, for a structure like this,
The part of the cam whose diameter increases from the short diameter part to the long diameter part (hereinafter referred to as the increasing diameter part) is used to push out the movable blade and cut the object to be cut. When using an increasing portion, the cutting force weakens as the movable blade closes and large cutting force cannot be exerted, so the cutting operation tends to be uncertain and is particularly unsuitable for cutting rigid objects. be.

In order to achieve the above object, the electric nipper of the present invention uses a solenoid as the drive mechanism of the piston that opens and closes the cutting edge of the nipper, a geared drive plate attached to the plunger of the solenoid, and a large shaft opposite to the drive plate. The piston is configured to include a large-diameter drive gear and a small-diameter pinion that drives a rack provided on the inner wall surface of the piston that is linked to the movement of the drive gear. In other words, the piston is driven by the meshing of the pinion and rack, which are operated by the suction force of the solenoid, so instantaneous operation is possible by turning on and off the power to the solenoid. The air supply and exhaust mechanism has been replaced with an electric mechanism, further improving ease of use.

し、刃先５を開閉する。 The nipper 1 is removably attached to a fixture 3 with screws 2 (allowing the nipper to be replaced), and a curved portion 4 is provided at one end of the grip of the nipper 1. The nipper 1 is screwed onto the fixture 3 so that it can be removed and replaced with a new one, since the cutting edge 5 of the nipper 1 may become worn out or damaged, for example, during long-term use. A cylindrical piston 6 for opening and closing the cutting edge 5 of the nipper is provided with a sloped portion 7 that contacts the curved portion 4 of the nipper, and is slidably fitted into the main body 8. A rack 10 for driving the piston is provided on the inner wall surface 9 on the opposite side of the piston where the sloped portion 7 is provided. The solenoid 11 that serves as the driving source for the piston 6 has a coil 13 for generating magnetic force wound around a bobbin 12, and the current flowing through the solenoid 11 is turned on and off by operating a switch lever 15 using a voltage applied via a power cord 14. This is done using a micro switch 16 that is linked to this. The solenoid 11 is installed inside the main body 8, and a plunger (movable iron core) 18 that operates by electromagnetic force is provided in the center hole 17 of the solenoid 11.
is inserted. A geared drive plate 19 is attached to the tip of the plunger 18. A rolling element is installed opposite the drive plate 19 and the rack 10 provided on the inner wall surface of the piston 6. The rotor is integrally provided with a drive gear 20 that meshes with the drive plate 19 and a pinion 21 that has the same rotation center but a different outer diameter, that is, a smaller outer diameter.
The driving force is amplified on the pinion 21 side. When the plunger 18 operates, its force is transmitted to the rack 10 via the drive plate 19, drive gear 20 and pinion 21, and the pinion 6 is operated. When the piston 6 operates, the slope portion 7 of the piston 6 and the curved portion 4 of the nipper slide as the piston 6 moves, opening and closing the cutting edge 5.

が行なわれる。 Note that when the nipper 1 is in a state where the switch lever 15 is open and no electricity is energized, the cutting edge 5 is opened by the force of the spring 22 provided on the nipper 1 and the pushing spring 23 of the plunger 18 [the state shown in FIG. 1 a],
When the switch lever 15 is pressed and the coil 13 is energized, the solenoid 11 generates magnetic force and attracts the plunger 18 against the force of the spring 23, and the blade edge 5 closes due to the attraction force (state shown in Fig. 1b) for cutting operation. will be carried out.

±2°が望ましい。 The slope θ of the slope portion 7 provided on the piston 6 is determined so as to increase the cutting force of the cutting edge of the nipper relative to the movement (movement amount) of the piston, and to make the movement and force efficient. From the experimental results, it is desirable that the slope θ is 30°±2°.

いことは言うまでもない。 The drive plate 19 has gears cut on the top and bottom, but this is to ensure that the force that operates the piston 6 is transmitted in a well-balanced manner. It goes without saying that you may also use .

ストン６の駆動力を高めている。 The gear that transmits power to the piston 6 uses a rolling element that integrates a driving gear 20 and a pinion 21 as shown in Fig. 2c, and this rolling element applies the suction force of the plunger 18 (solenoid). The driving force of the piston 6 is increased by amplifying it.
第２図ａ〜ｃに示した各部品の構成材料は製作
が容易で、しかも軽量化がはかれるプラスチツク
を用いるのが好ましいが、特にプラスチツクに限
定する必要はない。 It is preferable to use plastic, which is easy to manufacture and light in weight, as the constituent material of each part shown in FIGS. 2a to 2c, but it is not necessary to limit the material to plastic.
次に、上記本考案の電動ニツパの動作特性につ

動源として単相交流100Vの電源を用い約10Wの
消費電力で実現できる。 FIG. 3 is a characteristic diagram showing the relationship between the suction force of the solenoid, the cutting force of the cutting edge, and the stroke of the plunger, taking as an example a nipper with a maximum cutting force of 25 kg. In other words, this example shows the case of cutting a material with a shear stress of 25 kg or less (for example, an annealed copper wire with a diameter of 1.2 mm or less), and the stroke l of the plunger was approximately 10 mm.
It can be seen that the suction force of the solenoid 11 increases greatly as the solenoid approaches the solenoid 11 side. In the figure, the broken line indicates the shear stress of the wire to be cut. The suction force of the solenoid can be achieved with a power consumption of approximately 10W using a single-phase AC 100V power source as the drive source.
次に本考案の電動ニツパの特徴を要約し、それ
に伴う効果を列記する。
Next, we will summarize the features of the electric nipper of the present invention and list the effects associated with them.
(1) 従来、空気圧力を使用していたものを電動機
構に置換えた。それに伴い圧縮空気用付帯設備
が不要になつた。(1) The conventional system that used air pressure was replaced with an electric mechanism. As a result, additional equipment for compressed air became unnecessary.
(2) 圧縮空気を使用していないので騒音が軽減さ
れた。(2) Noise is reduced because compressed air is not used.
(3) 動力源は商用電源でよく、上記(1)，(2)と相俟
つて使用する場所はほとんど制約を受けない。
従つて家庭用，家内工業用としての需要に応え
られる。(3) The power source can be a commercial power source, and in conjunction with (1) and (2) above, there are almost no restrictions on the location where it can be used.
Therefore, it can meet the demand for home use and cottage industry.
(4) 刃先開閉機構のピストンに設けた勾配部、及
びピストンを作動する大径の駆動ギヤと小径の
ピニオンを設けた転動子により、ソレノイドの
吸引力を増幅して徐々に大きな駆動力を発揮す
るようになつているので、効率が良く比較的小
形（小容量）のソレノイドで充分大きな切断力
が得られる。(4) The suction force of the solenoid is amplified to gradually increase the driving force by using the slope part provided on the piston of the cutting edge opening/closing mechanism and the rotor equipped with a large diameter drive gear and small diameter pinion that operate the piston. Therefore, a sufficiently large cutting force can be obtained with a highly efficient and relatively small (small capacity) solenoid.
(5) 本体には従来使われていたエアーホースの代
りに電源コードがつながれているので、その部
分が軽量化され、柔軟性も格段に良くなり、作
業者の負担が大幅に軽減される。(5) Since the power cord is connected to the main body instead of the conventional air hose, that part is lighter and has much better flexibility, greatly reducing the burden on the operator.
(6) 駆動ギアから伝達されるピニオン側の駆動力
は常時一定値に大きく増幅されているが、特に
切断効果を高めるために電磁力により刃先を閉
じるにつれてしだいに大きな切断力が発生する
ようになつており、これによつて特に切断中期
から後期にかけて大きな切断力が得られるた
め、切断動作が確実で信頼度が高まる。(6) The driving force on the pinion side transmitted from the drive gear is always greatly amplified to a constant value, but in order to particularly improve the cutting effect, as the cutting edge is closed by electromagnetic force, a gradually larger cutting force is generated. This allows a large cutting force to be obtained, especially in the middle to late stages of cutting, making the cutting operation more reliable and reliable.
