本考案は、高周波加熱コイルに関し、特に曲線状に形成された加熱導体と、連 結部が曲線状に形成された加熱導体の側面に連結される導体とを有し、加熱導体 にコアが取り付けられる高周波加熱コイルに関する。 The present invention relates to a high-frequency heating coil, and in particular, it has a heating conductor formed in a curved shape and a conductor connected to a side surface of the heating conductor having a connecting portion formed in a curved shape, and a core is attached to the heating conductor. High frequency heating coil.

図６（Ｂ）を参照しつつ、曲線状に形成された加熱導体１２０、１６０と、曲 線状に形成された加熱導体１２０、１６０の側面に連結される導体１１０、１７ ０とを有し、加熱導体１２０、１６０にコア２００が取り付けられる従来の高周 波加熱コイルについて説明する。 With reference to FIG. 6B, the heating conductors 120 and 160 are formed in a curved shape, and the conductors 110 and 170 are connected to the side surfaces of the heating conductors 120 and 160 formed in a curved shape. A conventional high frequency heating coil in which the core 200 is attached to the heating conductors 120 and 160 will be described.
【０００３】 曲線状に形成された加熱導体１２０、１６０に取り付けられるコア２００は、 加熱導体１２０、１６０が発生する磁束の大半をワークＷの被焼入面に集中させ るために用いられるものである。ここで、高周波加熱コイルは、通常外寸が等し い角パイプを組み合わせて構成されている。このため、コア２００は略コ字形状 に形成されている。The core 200 attached to the heating conductors 120 and 160 formed in a curved shape is used to concentrate most of the magnetic flux generated by the heating conductors 120 and 160 on the surface to be hardened of the workpiece W. is there. Here, the high frequency heating coil is usually constructed by combining square pipes having the same outer dimensions. Therefore, the core 200 is formed in a substantially U shape.
【０００４】[0004]
高周波加熱コイルの導体１１０、１７０に連結される加熱導体１２０、１６０ が曲線状に形成されている場合、導体１１０、１７０に連結された加熱導体１２ ０、１６０にコア２００を取り付けると、図６（Ｂ）に示すように、導体１１０ 、１７０の角部に接する部分までしかコア２００が取り付けられない。 When the heating conductors 120, 160 connected to the conductors 110, 170 of the high-frequency heating coil are formed in a curved shape, when the core 200 is attached to the heating conductors 120, 160 connected to the conductors 110, 170, as shown in FIG. As shown in (B), the core 200 can be attached only to the portions in contact with the corners of the conductors 110 and 170.
【０００５】 このため、導体１１０、１７０と加熱導体１２０、１６０とが連結された部分 では、図７に示すように、ワークＷに形成された硬化層Ｗ1 は、破線で示すよう に急激に所定の深さにまで形成されるのが望ましいのであるが、連結された部分 にはコア２００が存在しないため硬化層Ｗ1 は実線で示したように所定の深さに なるまでの幅寸法を必要とする。特に、小径のワークＷに使用する高周波加熱コ イルになるほどこの傾向が強くなる。Therefore, at the portion where the conductors 110 and 170 and the heating conductors 120 and 160 are connected, the hardened layer W 1 formed on the work W as shown in FIG. It is desirable that the hardened layer W 1 is formed to a predetermined depth, but since the core 200 does not exist in the connected portion, the hardened layer W 1 has a width dimension until it reaches a predetermined depth as shown by the solid line. I need. In particular, this tendency becomes stronger as the high frequency heating coil used for the work W having a smaller diameter is used.
【０００６】 本考案は、上記事情に鑑みて創案されたもので、曲線状に形成された加熱導体 にも多くのコアを取り付けることができ、小径のワークであっても、導体の連結 部分でも硬化層が所定の深さにまで形成される高周波加熱コイルを提供すること を目的としている。The present invention was devised in view of the above circumstances, and many cores can be attached to a heating conductor formed in a curved shape, and it can be used for a work having a small diameter or a connecting portion of conductors. It is an object of the present invention to provide a high frequency heating coil in which a hardened layer is formed to a predetermined depth.

【０００９】 本実施例に係る高周波加熱コイル１００は、複数の加熱導体１２０〜１６０と 、この加熱導体１２０〜１６０に装着される珪素鋼板やフェライト等の磁性体か らなるコア２００とを有し、一対の電源供給導体１１０、１７０に連結される第 １弧状加熱導体１２０及び第２弧状加熱導体１６０が略円弧状、すなわち曲線状 に形成される高周波加熱コイルであって、各電源供給導体１１０、１７０の第１ 弧状加熱導体１２０及び第２弧状加熱導体１６０への連結部分１１１、１７１の 外寸が他の部分より細く設定されている。The high-frequency heating coil 100 according to the present embodiment has a plurality of heating conductors 120 to 160, and a core 200 made of a magnetic material such as silicon steel plate or ferrite mounted on the heating conductors 120 to 160. The first arc-shaped heating conductor 120 and the second arc-shaped heating conductor 160 connected to the pair of power supply conductors 110 and 170 are high-frequency heating coils formed in a substantially arc shape, that is, a curved shape. , 170 are connected to the first arc-shaped heating conductor 120 and the second arc-shaped heating conductor 160, and the outer dimensions of the connection parts 111 and 171 are set to be thinner than the other parts.
【００１０】 まず、高周波加熱コイルの全体の説明を行う。 図５に示すように、この高周波加熱コイルは、半開放のライン型コイルと呼ば れるものであって、一端に第１電源供給導体１１０が連結されたほぼ１／４円弧 の第１弧状加熱導体１２０と、この第１弧状加熱導体１２０の他端に連結される 第１直線状加熱導体１３０と、この第１直線状加熱導体１３０の他端に連結され るほぼ半円弧状の円弧状加熱導体１４０と、この円弧状加熱導体１４０の他端に 連結される第２直線状加熱導体１５０と、この第２直線状加熱導体１５０の他端 に連結されるほぼ１／４円弧の第２弧状加熱導体１６０と、この第２弧状加熱導 体１６０の他端に連結される第２電源供給導体１７０とを有している。First, the entire high frequency heating coil will be described. As shown in FIG. 5, this high-frequency heating coil is called a semi-open line type coil, and has a first arc-shaped heating conductor of approximately 1/4 arc whose first end is connected to the first power supply conductor 110. 120, a first linear heating conductor 130 connected to the other end of the first arc-shaped heating conductor 120, and a substantially semi-circular arc-shaped heating conductor connected to the other end of the first linear heating conductor 130. 140, a second linear heating conductor 150 connected to the other end of the arcuate heating conductor 140, and a second arcuate heating of approximately 1/4 arc connected to the other end of the second linear heating conductor 150. It has a conductor 160 and a second power supply conductor 170 connected to the other end of the second arc-shaped heating conductor 160.
【００１１】 これらの電源供給導体１１０、１７０及び加熱導体１２０〜１６０には冷却水 が循環するようになっている。Cooling water circulates through the power supply conductors 110 and 170 and the heating conductors 120 to 160.
【００１２】 第１電源供給導体１１０は第１弧状加熱導体１２０の一端の側面に、第２電源 供給導体１７０は第２弧状加熱導体１６０の一端の側面にそれぞれ連結されてい る。そして、第１弧状加熱導体１２０と第２弧状加熱導体１６０とは、２つで半 円弧状になるように組み合わされている。The first power supply conductor 110 is connected to a side surface of one end of the first arc-shaped heating conductor 120, and the second power supply conductor 170 is connected to a side surface of one end of the second arc-shaped heating conductor 160. The first arc-shaped heating conductor 120 and the second arc-shaped heating conductor 160 are combined so as to form a semicircular arc shape.
【００１３】 また、第１直線状加熱導体１３０と第２直線状加熱導体１５０とは、同じ長さ で平行に構成されている。さらに、円弧状加熱導体１４０は、第１弧状加熱導体 １２０と第２弧状加熱導体１６０とで構成されたほぼ半円弧に対して向かい合う ように構成されている。Further, the first linear heating conductor 130 and the second linear heating conductor 150 have the same length and are configured in parallel. Furthermore, the arc-shaped heating conductor 140 is configured to face a substantially semi-circular arc formed by the first arc-shaped heating conductor 120 and the second arc-shaped heating conductor 160.
【００１４】 すなわち、第１弧状加熱導体１２０と第２弧状加熱導体１６０とは同一形形状 、第１直線状加熱導体１３０と第２直線状加熱導体１５０とは同一形状にそれぞ れ構成されている。That is, the first arc-shaped heating conductor 120 and the second arc-shaped heating conductor 160 are formed in the same shape, and the first linear heating conductor 130 and the second linear heating conductor 150 are formed in the same shape. There is.
【００１５】 第１電源供給導体１１０は、断面略台形状の連結部１１１と、この連結部１１ に接続された垂直部１１２とからなる。垂直部１１２の断面は略四角形状に設定 されており、この垂直部１１２の断面積は連結部１１１の断面積より大きくなっ ている。すなわち、連結部１１１は、図２、図３及び図４に示すように、その下 面１１１Ｂの幅寸法Ｈ2 は上面１１１Ａの幅寸法Ｈ1 より小さく設定されている のである。このため、この連結部１１１の側面のうち、第１弧状加熱導体１２０ 側の側面１１１Ｃは内側に向かった傾斜面として形成されるのである。なお、第 １電源供給導体１２０と第２電源供給導体１６０とは対称に形成されているので 、第２電源供給導体１６０の詳細な説明は省略する。The first power supply conductor 110 includes a connecting portion 111 having a substantially trapezoidal cross section and a vertical portion 112 connected to the connecting portion 11. The vertical portion 112 has a substantially rectangular cross section, and the vertical portion 112 has a larger cross-sectional area than the connecting portion 111. That is, in the connecting portion 111, as shown in FIGS. 2, 3 and 4, the width dimension H 2 of the lower surface 111B is set smaller than the width dimension H 1 of the upper surface 111A. Therefore, among the side surfaces of the connecting portion 111, the side surface 111C on the first arc-shaped heating conductor 120 side is formed as an inclined surface facing inward. Since the first power supply conductor 120 and the second power supply conductor 160 are formed symmetrically, detailed description of the second power supply conductor 160 will be omitted.
【００１６】 上述したように構成された高周波加熱コイル１００に取り付けられるコア２０ ０は、通常のものであって、珪素鋼板やフェライト等の磁性体から構成されてい る。かかるコア２００は、略コ字形状に形成されており、各加熱導体の所要箇所 に外側から嵌め込まれることで取り付けられるようになっている。The core 200 attached to the high-frequency heating coil 100 configured as described above is a normal core and is made of a magnetic material such as a silicon steel plate or ferrite. The core 200 is formed in a substantially U shape, and is attached by being fitted from the outside to a required portion of each heating conductor.
【００１７】 このように構成された第１及び第２電源供給導体１１０、１７０が連結された 第１及び第２弧状加熱導体１２０、１６０にコア２００を取り付けると、各連結 部１１１、１７１の第１及び第２弧状加熱導体１２０、１６０側の側面１１１Ｃ は下方向に向かって傾斜しているので、この側面１１１Ｃに沿ってコア２００を 取り付けることができる。すなわち、この側面１１１Ｃが傾斜している分だけ多 くのコア２００を第１弧状加熱導体１２０に取り付けることが可能になるのであ る。When the core 200 is attached to the first and second arc-shaped heating conductors 120 and 160 to which the first and second power supply conductors 110 and 170 configured as described above are connected, the first and second arc-shaped heating conductors 120 and 160 of the connection parts 111 and 171 are connected. Since the side surface 111C on the first and second arc-shaped heating conductors 120 and 160 side is inclined downward, the core 200 can be attached along the side surface 111C. That is, as much as the side surface 111C is inclined, more cores 200 can be attached to the first arc-shaped heating conductor 120.
【００１８】 図６（Ａ）に示すように、２つの弧状加熱導体１２０、１６０の間でコア２０ ０が取り付けられていない角度θ1 は、図６（Ｂ）に示すように、従来の高周波 加熱コイルで同様にコア２００が取り付けられていない角度θ2 より小さくなっ ている。As shown in FIG. 6 (A), the angle θ 1 between the two arcuate heating conductors 120 and 160 where the core 200 is not attached is as shown in FIG. Similarly, the heating coil is smaller than the angle θ 2 where the core 200 is not attached.
【００１９】 なお、上述した実施例では、連結部１１１の断面は略台形状であるとして説明 したが、本考案がこれに限定されるわけではない。例えば、連結部１１１の断面 は、略三角形状であってもよい。この場合には、連結部１１１の下面１１１Ｂに 相当する部分は存在しなくなる。In addition, in the above-described embodiment, the cross-section of the connecting portion 111 is described as being substantially trapezoidal, but the present invention is not limited to this. For example, the cross section of the connecting portion 111 may have a substantially triangular shape. In this case, the portion corresponding to the lower surface 111B of the connecting portion 111 does not exist.

本考案に係る高周波加熱コイルは、曲線状に形成された加熱導体と、連結部が 前記曲線状に形成された加熱導体の側面に連結される導体とを有し、前記加熱導 体にコアが取り付けられる高周波加熱コイルであって、前記導体の連結部は導体 の他の部分より細く形成されている。しかも、当該連結部は、下面の幅寸法は上 面の幅寸法より小さく設定されており、この連結部の側面のうち、加熱導体側の 側面は内側に向かった傾斜面として形成されている。従って、加熱導体と導体と の連結部分にも従来より多くのコアを取り付けることが可能になり、小径のワー クであっても、導体の連結部分でも硬化層が所定の深さにまで形成されるように なる。 A high frequency heating coil according to the present invention has a heating conductor formed in a curved shape and a conductor having a connecting portion connected to a side surface of the heating conductor formed in the curved shape, and the heating conductor has a core. In the high frequency heating coil to be attached, the connecting portion of the conductor is formed thinner than other portions of the conductor. Moreover, the width dimension of the lower surface of the connecting portion is set to be smaller than the width dimension of the upper surface, and the side surface of the connecting portion on the heating conductor side is formed as an inclined surface facing inward. Therefore, it is possible to attach more cores to the connecting portion between the heating conductor and the conductor than before, and even if the work has a small diameter, the hardened layer is formed to a predetermined depth even at the connecting portion of the conductor.
