本発明の実施例に係るフューズ用バスバー製造方法について図面を参照して詳細に説明する。 The method for manufacturing a bus bar for fuse according to an embodiment of the present invention will be described in detail with reference to the drawings.
図１は、本発明の第１実施例に係るフューズ用バスバー製造方法を説明するフローチャートであり、図２は本発明の第１実施例に係るフューズ用バスバー製造方法によって製造されたフューズ用バスバーを説明する図面である。 FIG. 1 is a flowchart illustrating a fuse bus bar manufacturing method according to the first embodiment of the present invention, and FIG. 2 shows a fuse bus bar manufactured by the fuse bus bar manufacturing method according to the first embodiment of the present invention. It is a drawing to explain.
図１および図２を参照すると、まず、移送装置を利用してバッテリーなどの電源側に接続される電源側接続部と電装部品の負荷側に接続される負荷側接続部間に補強部を配置するＳ１００。 Referring to FIGS. 1 and 2, first, a reinforcing portion is arranged between a power supply side connection portion connected to the power supply side such as a battery and a load side connection portion connected to the load side of an electrical component by using a transfer device. S100 to do.
前述した段階Ｓ１００において、バッテリーなどの電源側から供給される電気が電源側接続部、補強部、負荷側接続部の順序に移動して負荷側に供給され得る。 In step S100 described above, electricity supplied from the power supply side such as a battery may move in the order of the power supply side connection portion, the reinforcement portion, and the load side connection portion and be supplied to the load side.
前述した段階Ｓ１００において、電源側接続部と負荷側接続部は電気接点が発生する部分であるので、相対的に電気伝導度が高く溶融点が高い銅金属からなることが好ましい。 In the above-mentioned step S100, since the power supply side connection portion and the load side connection portion are portions where electrical contacts are generated, it is preferably made of a copper metal having a relatively high electric conductivity and a high melting point.
前述した段階Ｓ１００において、補強部は、相対的に軽くて安価の素材であるアルミニウム金属からなり得る。アルミニウム金属は溶融点が低いため、過電流が流れる場合、温度が上がって溶断されるようにして電源側接続部から負荷側接続部の間の電気的な連結を自動で分離させることができる。これによって過負荷の電装部品に電気が供給されないため、電装部品が過負荷によって損傷する現象を防止することができる。 In step S100 described above, the reinforcement may be made of aluminum metal, which is a relatively light and inexpensive material. Since the aluminum metal has a low melting point, when an overcurrent flows, the temperature rises and the aluminum metal is blown so that the electrical connection between the power supply side connection portion and the load side connection portion can be automatically separated. As a result, electricity is not supplied to the overloaded electrical component, so that it is possible to prevent the phenomenon that the electrical component is damaged by the overload.
前述した段階Ｓ１００において、補強部は、銅、マグネシウム、亜鉛、ケイ素、鉄、ニッケルのうち少なくとも一つ以上とアルミニウムを組み合わせて作った合金からなり得る。したがって、アルミニウム合金からなる補強部の強度が向上するため、外部の衝撃などによって不要なクラックが発生する現象を防止することができる。 In step S100 described above, the stiffener may consist of an alloy made by combining aluminum with at least one of copper, magnesium, zinc, silicon, iron and nickel. Therefore, since the strength of the reinforcing portion made of an aluminum alloy is improved, it is possible to prevent a phenomenon in which unnecessary cracks are generated due to an external impact or the like.
前述した段階Ｓ１００において、電源側接続部、補強部および負荷側接続部は互いに密着するように配置して、電源側接続部、補強部および負荷側接続部が互いに浮く現象が発生しないようにすることができる。 In step S100 described above, the power supply side connection portion, the reinforcing portion, and the load side connection portion are arranged so as to be in close contact with each other so that the phenomenon that the power supply side connection portion, the reinforcement portion, and the load side connection portion do not float from each other does not occur. be able to.
前述した段階Ｓ１００で配置された電源側接続部と補強部間および負荷側接続部と補強部間を溶接機を利用して溶接するＳ２００。 S200 for welding between the power supply side connection portion and the reinforcing portion and between the load side connection portion and the reinforcing portion arranged in the above-mentioned step S100 by using a welding machine.
前述した段階Ｓ２００において、電源側接続部と補強部間および負荷側接続部と補強部間を摩擦溶接機を利用して摩擦溶接することができる。 In the above-mentioned step S200, friction welding can be performed between the power supply side connection portion and the reinforcing portion and between the load side connection portion and the reinforcing portion by using a friction welder.
摩擦溶接は、素材を１分に１６００−２２００ｒｐｍで回転させながら３−１０ｔｏｎの範囲で停止した素材の側面を加圧して接触面で１０００−１４００℃の摩擦熱が発生するようにし、その後、回転する素材を停止させるとともに接触面の方向で７−２０ｔｏｎの範囲で再度加圧して接触面を焼成変形させることによって溶接する方式である。 In friction welding, the material is rotated at 1600-2200 rpm per minute and the side surface of the material stopped in the range of 3-10 ton is pressurized so that frictional heat of 1000-1400 ° C is generated on the contact surface, and then the rotation is performed. It is a method of welding by stopping the material to be welded and pressurizing it again in the range of 7 to 20 tons in the direction of the contact surface to deform the contact surface by firing.
前述した段階Ｓ２００において、電源側接続部と補強部および負荷側接続部を摩擦溶接機に装着し、回転力によって電源側接続部と補強部および補強部と負荷側接続部を相互に逆方向に回転させ、電源側接続部と補強部および補強部と負荷側接続部の密着面で発生する摩擦熱によって接合させることができる。 In the above-mentioned stage S200, the power supply side connection portion, the reinforcing portion, and the load side connection portion are mounted on the friction welder, and the power supply side connection portion and the reinforcement portion and the reinforcement portion and the load side connection portion are reversed from each other by rotational force. It can be rotated and joined by frictional heat generated on the contact surface between the power supply side connection portion and the reinforcing portion and the reinforcing portion and the load side connection portion.
前述した段階Ｓ２００において、電源側接続部と補強部および負荷側接続部を相互に逆方向に既設定された回転速度（例えば、１分に１６００〜２２００ｒｐｍなど）で回転させることができ、電源側接続部と補強部および負荷側接続部の密着面の摩擦熱が既設定された温度（例えば、電源側接続部と補強部および負荷側接続部の融点など）に到達するまで回転させることができる。 In the above-mentioned step S200, the power supply side connection portion, the reinforcement portion, and the load side connection portion can be rotated in opposite directions at a preset rotation speed (for example, 1600 to 2200 rpm per minute), and the power supply side can be rotated. It can be rotated until the frictional heat of the contact surface between the connection part and the reinforcement part and the load side connection part reaches a preset temperature (for example, the melting point of the power supply side connection part and the reinforcement part and the load side connection part). ..
前述した段階Ｓ２００において、電源側接続部と補強部および負荷側接続部が互いに密着した状態で相互に逆方向に回転する間に密着面方向に７〜２０ｔｏｎ範囲で加圧力を提供することができる。 In step S200 described above, it is possible to provide a pressing force in the range of 7 to 20 tons in the contact surface direction while the power supply side connection portion, the reinforcing portion, and the load side connection portion rotate in opposite directions while being in close contact with each other. ..
前述した段階Ｓ２００で溶接された電源側接続部、補強部および負荷側接続部を既設定された形（例えば、板状、円柱状）および厚さで圧着または圧延してバスバーを形成するＳ３００。 S300 for forming a bus bar by crimping or rolling the power supply side connection portion, the reinforcing portion and the load side connection portion welded in the above-mentioned step S200 in a preset shape (for example, plate shape or columnar shape) and thickness.
前述した段階Ｓ３００において、溶接された電源側接続部、補強部および負荷側接続部を複数のエンボシングが備えられた板で圧着してバスバーを形成することができる。この時、エンボシングにより接触面積が広くなるため、電源側接続部、補強部および負荷側接続部間がさらに堅固に結合する効果がある。 In step S300 described above, the welded power supply side connection portion, reinforcement portion, and load side connection portion can be crimped with a plate provided with a plurality of embossings to form a bus bar. At this time, since the contact area is widened by embossing, there is an effect that the power supply side connection portion, the reinforcing portion, and the load side connection portion are more firmly coupled.
前述した段階Ｓ３００において、接触された電源側接続部、補強部および負荷側接続部を複数のエンボシングが備えられたロールで圧延してバスバーを形成することができる。この時、エンボシングにより接触面積が広くなって電源側接続部、補強部および負荷側接続部間がさらに堅固に結合する効果がある。 In step S300 described above, the contacted power supply side connection portion, reinforcement portion and load side connection portion can be rolled with a roll provided with a plurality of embossings to form a bus bar. At this time, the contact area is widened by embossing, and there is an effect that the power supply side connection portion, the reinforcing portion and the load side connection portion are more firmly coupled.
前述した段階Ｓ３００で形成されたバスバーを切断機を利用して所望の大きさで切断することができ、バスバーの両端をパンチングしてホールを形成することによって、そのホールにボルトを貫通させてフューズボックスなどに装着することができる。 The bus bar formed in the above-mentioned step S300 can be cut to a desired size by using a cutting machine, and by punching both ends of the bus bar to form a hole, a bolt is passed through the hole to fuse. It can be attached to a box or the like.
