【０００５】 移動焼入コイル20によってワーク10の外周面11を焼入するには、移動焼入コイ ル20の加熱導体22、24をワーク10の軸芯線12の方向で外周面11に接近し対向する ように配設すると共に、加熱導体21、23、および25をワーク周方向で外周面11に 接近し対向するように配設した後、ワーク10を軸芯線12を中心として回転させる 。In order to quench the outer peripheral surface 11 of the work 10 with the moving quenching coil 20, the heating conductors 22 and 24 of the moving quenching coil 20 are brought close to the outer circumferential surface 11 in the direction of the axis 12 of the work 10.

It has and.
【００１３】 移動焼入コイル100 は、また、一端が加熱導体102 の他端に接続され、他端が 一方のリード導体110 を介して高周波電源130 の一端に接続されたほぼ１／４円 弧状の加熱導体101 （第４加熱導体）と、一端が加熱導体108 の他端に接続され 、他端が他方のリード導体111 を介して高周波電源130 の他端に接続されたほぼ １／４円弧状の加熱導体109 （第５加熱導体）と、加熱導体104 と加熱導体106 の他端同士を接続するほぼ１／２円弧状の加熱導体105 （第６加熱導体）とを備 えている。The moving quenching coil 100 also has an approximately ¼ arc shape with one end connected to the other end of the heating conductor 102 and the other end connected to one end of the high frequency power supply 130 via the one lead conductor 110. Of the heating conductor 101 (fourth heating conductor) and one end of which is connected to the other end of the heating conductor 108, and the other end of which is connected to the other end of the high frequency power supply 130 via the other lead conductor 111. It is provided with an arc-shaped heating conductor 109 (fifth heating conductor) and an approximately 1/2 arc-shaped heating conductor 105 (sixth heating conductor) that connects the other ends of the heating conductor 104 and the heating conductor 106.
【００１４】 そして、全ての加熱導体101 〜109 が直列に接続されていると共に、加熱導体 101 〜104 と加熱導体105 の半分とによって、第１の１ターンの加熱コイル 100 Ａが構成され、また、加熱導体105 の残りの半分と、加熱導体106 〜109 とによ って第２の１ターンの加熱コイル 100Ｂが構成されている。即ち、移動焼入コイ ル100 は２個の半開放鞍型がほぼ同じ位置に配設され、且つ直列に接続された構 成となっている。All the heating conductors 101 to 109 are connected in series, and the heating conductors 101 to 104 and half of the heating conductors 105 constitute a first one-turn heating coil 100A. The other half of the heating conductor 105 and the heating conductors 106 to 109 form a second one-turn heating coil 100B. That is, the moving quenching coil 100 is configured such that two half-open saddle types are arranged at substantially the same position and are connected in series.
【００１５】 なお、各加熱導体101 〜109 はワーク10の外周面11に接近し対向するように配 設されている。また、各加熱導体101 〜109 は良導電金属四角管より構成されて おり、これら導体の中空部分は移動焼入コイル100 の冷却液の流通路となってい る。The heating conductors 101 to 109 are arranged so as to approach the outer peripheral surface 11 of the work 10 and face each other. Each of the heating conductors 101 to 109 is made of a good conductive metal square tube, and the hollow portion of these conductors serves as a flow passage for the cooling liquid of the moving quenching coil 100.
【００１６】 図２に示すように、加熱導体106 は加熱導体102 の反リード導体110 側に配置 されており、加熱導体108 は加熱導体104 の反リード導体110 側に配置されてい る。そして、加熱導体102 および104 のそれぞれ加熱導体106 および108 に対向 した面は、本実施例では、ワーク10の直径13の一方側および他方側の延長線上に あるように加熱導体102 、104 が配置されている。従って、移動焼入コイル100 は、ワーク10の外周面11の半周を少し越えた部分をカバーしている。As shown in FIG. 2, the heating conductor 106 is arranged on the opposite lead conductor 110 side of the heating conductor 102, and the heating conductor 108 is arranged on the opposite lead conductor 110 side of the heating conductor 104. In the present embodiment, the surfaces of the heating conductors 102 and 104 facing the heating conductors 106 and 108 are arranged on the extension lines of one side and the other side of the diameter 13 of the workpiece 10 so that the heating conductors 102 and 104 are arranged. Has been done. Therefore, the moving and quenching coil 100 covers a portion of the outer peripheral surface 11 of the work 10 which slightly exceeds a half circumference.
【００１７】 なお、ワーク10の周方向に対する加熱導体102 、106 の合成された幅、および 加熱導体104 、108 の合成された幅のそれぞれの寸法C1は、従来の移動焼入コイ ル20の前記寸法C0にほぼ等しくなるように、加熱導体102 、106 、104 、および 108 が形成、配設されている。また、移動焼入コイル100 の寸法L1およびD1は、 それぞれ、従来の移動焼入コイル20の寸法L0およびD0に対応し、寸法L0およびD0 にそれぞれほぼ等しくなるように各加熱導体が形成配置されている。The dimensions C1 of the combined width of the heating conductors 102 and 106 and the combined width of the heating conductors 104 and 108 in the circumferential direction of the work 10 are the same as those of the conventional moving quenching coil 20.

【００１８】 図３に示すように、加熱導体103 は加熱導体107 のリード導体110 側にあり、 加熱導体101 は軸芯線12の方向においてリード導体110 と同じ位置にあり、加熱 導体105 は加熱導体101 の反加熱導体107 側に、また、加熱導体109 は加熱導体 105 の反加熱導体107 側に位置している。As shown in FIG. 3, the heating conductor 103 is on the lead conductor 110 side of the heating conductor 107, the heating conductor 101 is at the same position as the lead conductor 110 in the direction of the shaft core 12, and the heating conductor 105 is the heating conductor. 101 is located on the non-heating conductor 107 side, and heating conductor 109 is located on the non-heating conductor 107 side of heating conductor 105.
【００１９】 次に、加熱導体の支持方法を、加熱導体102 、106 を例にとって説明する。図 ４に示すように、加熱導体102 は、部分的に示したコイル支持筐体120 に１対の ナット122 によって固定されたボルト121 の先端にろう付けによって固定されて いる。Next, a method of supporting the heating conductors will be described by taking the heating conductors 102 and 106 as an example. As shown in FIG. 4, the heating conductor 102 is fixed by brazing to the tips of bolts 121 fixed by a pair of nuts 122 to a coil supporting casing 120, which is partially shown.
【００２０】 また、加熱導体106 は、コイル支持筐体120 に１対のナット124 によって固定 されたボルト123 の先端の図示しない切り割り部分に挿入されろう付けによって 固定されたコイル支持板125 に、ろう付けによって固定されている。加熱導体10 2 、106 以外の加熱導体も加熱導体102 或いは106 とほぼ同じ支持要領でコイル 支持筐体120 から支持されている。The heating conductor 106 is soldered to the coil support plate 125 fixed to the coil support housing 120 by brazing by inserting it into a notched portion of the bolt 123 fixed to the coil support housing 120 by a pair of nuts 124. It is fixed by attachment. The heating conductors other than the heating conductors 102 and 106 are also supported by the coil supporting housing 120 in the same manner as the heating conductors 102 and 106.
【００２１】 以下、移動焼入コイル100 を用いてワーク10の外周面11を移動焼入する方法に ついて説明する。移動焼入コイル100 をワーク10の外周面11に接近し対向するよ うに配置する。即ち、加熱導体102 、104 、106 、および108 がワーク10の軸芯 線12の方向に、加熱導体101 、103 、105 、107 、および109 がワーク10の周方 向に配置される。A method of moving and quenching the outer peripheral surface 11 of the work 10 using the moving quenching coil 100 will be described below. The moving quenching coil 100 is arranged so as to approach the outer peripheral surface 11 of the work 10 and face it. That is, the heating conductors 102, 104, 106, and 108 are arranged in the direction of the axis 12 of the work 10, and the heating conductors 101, 103, 105, 107, and 109 are arranged in the circumferential direction of the work 10.
【００２２】 次いで、ワーク10を軸芯線12を中心として回転させながら、高周波電源130 を 動作させると、高周波電流が、リード導体110 、加熱導体101 〜109 、およびリ ード導体111 の経路で、或いは、この経路と逆の経路で流れる。そして、高周波 電源の動作の開始と共に、移動焼入コイル100 を矢印Ｐの方向に移動させると、 各加熱導体101 〜109 によって外周面11が加熱される。Next, when the high-frequency power source 130 is operated while rotating the workpiece 10 about the axis 12 as a center, the high-frequency current is generated in the paths of the lead conductor 110, the heating conductors 101 to 109, and the lead conductor 111. Alternatively, it flows in a route opposite to this route. When the moving and quenching coil 100 is moved in the direction of arrow P with the start of the operation of the high frequency power supply, the outer peripheral surface 11 is heated by the heating conductors 101 to 109.
【００２３】 なお、移動焼入コイル100 の移動方向に移動焼入コイル100 と同期して移動す る図示しない焼入液噴射用ジャケットから、加熱された外周面11に焼入液が噴射 されて外周面11が焼入される。なお、移動焼入コイル100 を移動させる代わりに 、ワーク10を軸芯線12に沿って矢印Ｐと反対方向に移動させてもよい。A quenching solution is jetted onto the heated outer peripheral surface 11 from a quenching solution jetting jacket (not shown) that moves in the moving direction of the moving quenching coil 100 in synchronization with the moving quenching coil 100. The outer peripheral surface 11 is quenched. Instead of moving the moving and quenching coil 100, the work 10 may be moved along the axis 12 in the direction opposite to the arrow P.
【００２４】 上記の移動焼入に際しては、移動焼入コイル100 が、前述のように従来の移動 焼入コイル20の寸法L0、D0、およびC0とそれぞれほぼ同じ寸法L1、D1、およびC1 である上、２ターンのコイルであるので、従来の移動焼入コイル20に比べてイン ダクタンスが４倍程度となっている。In the above-mentioned moving quenching, the moving quenching coil 100 has dimensions L1, D1 and C1 which are substantially the same as the dimensions L0, D0 and C0 of the conventional moving quenching coil 20 as described above. In addition, since it is a two-turn coil, the inductance is about four times that of the conventional moving quenching coil 20.
【００２５】 従って、従来の移動焼入コイル20への印加電圧の２倍を越え、４倍未満の電圧 を移動焼入コイル100 に印加することによって、移動焼入コイル100 には、従来 の移動焼入コイル20に印加された電力を越える電力を、しかも従来の移動焼入コ イル20の通電電流より小さい通電電流でもって印加することができるから、移動 焼入コイル100 は従来の移動焼入コイル20より大きな電力をワーク10に与えるこ とができ、しかも、移動焼入コイル100 を劣化させる発熱が少なく、従って、移 動焼入コイル100 の寿命が長くなる。Therefore, by applying a voltage that is more than twice and less than four times the voltage applied to the conventional moving and quenching coil 20 to the moving and quenching coil 100, the moving and quenching coil 100 has a conventional moving Since the electric power exceeding the electric power applied to the quenching coil 20 can be applied with an energizing current smaller than the energizing current of the conventional moving quenching coil 20, the moving quenching coil 100 is a conventional moving quenching coil. The work 10 can be supplied with electric power larger than that of the coil 20, and less heat is generated which deteriorates the moving and quenching coil 100, so that the life of the moving and quenching coil 100 is extended.

Two parallel arc-shaped heating conductors 203, 207, and 211 (third heating conductor) are provided. .
【００２８】 移動焼入コイル200 は、また、一端が加熱導体202 の他端に接続され、他端が 一方のリード導体214 を介して高周波電源230 の一端に接続されたほぼ１／４円 弧状の加熱導体201 （第４加熱導体）と、一端が加熱導体212 の他端に接続され 、他端が他方のリード導体215 を介して高周波電源230 の他端に接続されたほぼ １／４円弧状の加熱導体213 （第５加熱導体）と、加熱導体204 と加熱導体206 の他端同士、および加熱導体208 と加熱導体210 の他端同士をそれぞれ接続する ほぼ１／２円弧状の平行な２個の加熱導体205 および209 （第６加熱導体）とを 備えている。The moving quenching coil 200 also has an approximately 1/4 circular arc shape, one end of which is connected to the other end of the heating conductor 202 and the other end of which is connected to one end of the high frequency power supply 230 via the one lead conductor 214. Of the heating conductor 201 (fourth heating conductor) and one end of which is connected to the other end of the heating conductor 212, and the other end of which is connected to the other end of the high frequency power supply 230 through the other lead conductor 215. The arc-shaped heating conductor 213 (fifth heating conductor), the other ends of the heating conductor 204 and the heating conductor 206, and the other ends of the heating conductor 208 and the heating conductor 210 are connected to each other. It has two heating conductors 205 and 209 (sixth heating conductor).
【００２９】 そして、全ての加熱導体201 〜213 が直列に接続されていると共に、加熱導体 201 〜204 と加熱導体205 の半分とによって第１の１ターンの加熱コイル 200Ａ が構成され、また、加熱導体205 の残りの半分と加熱導体206 〜208 と加熱導体 209 の半分とによって第２の１ターンの加熱コイル 200Ｂが構成され、更に、加 熱導体209 の残りの半分と加熱導体210 〜213 とによって第３の１ターンの加熱 コイル 200Ｃが構成されている。即ち、移動焼入コイル200 は３個の半開放鞍型 コイルがほぼ同じ位置に配置され、且つ直列に接続された構成となっている。Then, all the heating conductors 201 to 213 are connected in series, and the heating conductors 201 to 204 and half of the heating conductor 205 constitute a first one-turn heating coil 200A, and The second half of the heating coil 200B is constituted by the other half of the conductor 205, the heating conductors 206 to 208 and the half of the heating conductor 209, and the other half of the heating conductor 209 and the heating conductors 210 to 213. The third one-turn heating coil 200C is constituted by. That is, the moving quenching coil 200 has three semi-open saddle type coils arranged at substantially the same position and connected in series.
【００３０】 なお、各加熱導体201 〜213 はワーク10の外周面11に接近し対向するように配 設されている。また、各加熱導体201 〜213 は良導電金属四角管より構成されて おり、これら導体の中空部分は移動焼入コイル200 の冷却液の流通路となってい る。The heating conductors 201 to 213 are arranged so as to approach the outer peripheral surface 11 of the work 10 and face each other. Each of the heating conductors 201 to 213 is made of a good conductive metal square tube, and the hollow portion of these conductors serves as a flow passage for the cooling liquid of the moving quenching coil 200.
【００３１】 図６に示すように、加熱導体202 は加熱導体206 のリード導体214 側に配置さ れており、加熱導体210 は加熱導体206 の反リード導体214 側に配置されている 。また、加熱導体204 は加熱導体208 のリード導体214 側に配置されており、加 熱導体212 は加熱導体208 の反リード導体214 側に配置されている。As shown in FIG. 6, the heating conductor 202 is arranged on the lead conductor 214 side of the heating conductor 206, and the heating conductor 210 is arranged on the non-lead conductor 214 side of the heating conductor 206. The heating conductor 204 is arranged on the side of the lead conductor 214 of the heating conductor 208, and the heating conductor 212 is arranged on the side of the heating conductor 208 opposite to the lead conductor 214.
【００３２】 また、移動焼入コイル200 の寸法L2、D2、およびC2は、それぞれ、従来の移動 焼入コイル20の寸法L0、D0、およびC0に対応し、寸法L0、D0、およびC0にそれぞ れほぼ等しくなるように各加熱導体が形成配置されている。Further, the dimensions L2, D2, and C2 of the moving quenching coil 200 correspond to the dimensions L0, D0, and C0 of the conventional moving quenching coil 20, respectively, and are set to the dimensions L0, D0, and C0. The heating conductors are formed and arranged so that they are substantially equal to each other.
【００３３】 そして、本実施例では、加熱導体206 および208 の中央部分が、ワーク10の直 径13の一方側および他方側の延長線上にそれぞれ位置するように加熱導体206 、 208 が配置されている。従って、移動焼入コイル200 は、ワーク10の外周面11の 半周を少し越えた部分をカバーしている。In this embodiment, the heating conductors 206 and 208 are arranged such that the central portions of the heating conductors 206 and 208 are located on the extension lines of the one side and the other side of the diameter 13 of the work 10, respectively. There is. Therefore, the moving quenching coil 200 covers a portion of the outer peripheral surface 11 of the work 10 that slightly exceeds a half circumference.
【００３４】 移動焼入コイル200 によるワーク10の外周面11の移動焼入は、移動焼入コイル 100 によるワーク10の外周面11の上述の移動焼入と同じ要領で行うことができる 。この移動焼入に際しては、移動焼入コイル200 が、前述のように従来の移動焼 入コイル20の寸法L0、D0、およびC0とそれぞれほぼ同じ寸法L2、D2、およびC2で ある上、３ターンのコイルであるので、従来の移動焼入コイル20に比べてインダ クタンスが９倍程度となっている。The moving quenching of the outer peripheral surface 11 of the work 10 by the moving quenching coil 200 can be performed in the same manner as the above-mentioned moving hardening of the outer circumferential surface 11 of the work 10 by the moving quenching coil 100. In this moving quenching, the moving quenching coil 200 has dimensions L2, D2, and C2 that are substantially the same as the dimensions L0, D0, and C0 of the conventional moving quenching coil 20 as described above, and also has three turns. Since it is the above coil, the inductance is about 9 times that of the conventional moving quenching coil 20.
【００３５】 従って、従来の移動焼入コイル20への印加電圧の３倍を越え、９倍未満の電圧 を移動焼入コイル100 に印加することによって、移動焼入コイル100 には、従来 の移動焼入コイル20に印加された電力を越える電力を、しかも従来の移動焼入コ イル20の通電電流より小さい通電電流でもって印加することができるから、移動 焼入コイル200 は従来の移動焼入コイル20より大きな電力をワーク10に与えるこ とができ、しかも、移動焼入コイル200 を劣化させる発熱が少なく、従って、移 動焼入コイル200 の寿命が長くなる。Therefore, by applying a voltage to the moving and quenching coil 100 that is more than 3 times and less than 9 times the voltage applied to the conventional moving and quenching coil 20, the moving and quenching coil 100 is moved by the conventional moving and quenching coil 100. Since the electric power exceeding the electric power applied to the quenching coil 20 can be applied with an energizing current smaller than the energizing current of the conventional moving quenching coil 20, the moving quenching coil 200 is a conventional moving quenching coil. The work 10 can be supplied with electric power larger than that of the coil 20, and less heat is generated which deteriorates the moving and quenching coil 200, so that the life of the moving and quenching coil 200 is extended.
【００３６】 なお、前記第１および第２実施例とも、移動焼入コイル100 および200 はワー ク10の外周面11の半周を少し越えた部分をカバーしている場合を説明したが、必 ずしもこれにこだわるのではなく、要求される焼入仕様によっては、半周以下を カバーするようにしてもよい。In each of the first and second embodiments, the case has been described in which the moving and quenching coils 100 and 200 cover a portion of the outer peripheral surface 11 of the work 10 which is slightly over a half circumference, but it is inevitable. However, instead of sticking to this, depending on the required quenching specifications, it is possible to cover less than half the circumference.
【００３７】[0037]
以上説明したように、ほぼ丸棒状ワークの移動焼入コイルは、複数の半開放鞍 型コイルが、ほぼ同じ位置に配置され、且つ直列に接続された構成となっている ので、従来の移動焼入コイルに比べてインダクタンスが大きい。従って、本考案 のほぼ丸棒状ワークの高周波移動焼入コイルを使用すれば、コイルの印加電圧を 大きくし、しかも従来より小さい通電電流でもって、従来よりも大きい電力を移 動焼入コイルに与えることが可能であるから、焼入移動速度をより速くすること ができる上、コイルを劣化させる発熱が従来のコイルより少ないのでコイルの寿 命が長くなる。 As described above, the moving quenching coil for a substantially round bar-shaped work has a configuration in which a plurality of half-open saddle coils are arranged at approximately the same position and connected in series, so that the conventional moving quenching coil is used. Larger inductance than the input coil. Therefore, by using the high-frequency moving quenching coil of the present invention having a substantially round bar-like work, the voltage applied to the coil can be increased, and a larger current than before can be applied to the moving quenching coil with a current smaller than before. Therefore, the quenching movement speed can be increased, and since the heat generation that deteriorates the coil is less than that of the conventional coil, the life of the coil is extended.
