Air is supplied from the air supply mechanism to the jacket after heat treatment, and the work is reciprocated while injecting air to the work. During this vertical reciprocation of the work, the cooling liquid that has reached the surface of the work is blown away by the air, and the remaining liquid is also evaporated by the heat of the work and becomes completely dry.
Description
【０００１】[0001]
本考案は、高周波焼入れ装置に関するものである。 The present invention relates to an induction hardening device.
【０００２】[0002]
例えば、カムシャフトの高周波焼入れ装置は、図１に示すように、固定した高 周波コイル１とジャケット２の中に、ワークＷを回転させながら上下方向に移動 させ、高周波コイル１で表層を焼入れ温度に加熱したワークＷに、焼入れ液を噴 射し、急冷して焼入れ処理を行うようにしている。また、焼戻し処理は、同じ装 置の高周波コイル１の出力を低下させた状態で再度ワークＷを焼戻し温度に加熱 し、冷却することで焼戻し処理を行うようにしている。 For example, as shown in FIG. 1, a high-frequency induction hardening apparatus for a camshaft moves a work W vertically in a fixed high-frequency coil 1 and a jacket 2 while rotating the work W, and the high-frequency coil 1 heats the surface layer to a quenching temperature. A quenching solution is sprayed onto the workpiece W heated to the above temperature, and the workpiece W is rapidly cooled for quenching treatment. Further, in the tempering process, the work W is heated to the tempering temperature again with the output of the high frequency coil 1 of the same device being reduced, and then cooled to perform the tempering process.
【０００３】 実開昭６０−１５２６６８号公報には、上記のような高周波焼入れ装置におい て、焼入れ液の噴射方向をワークに対し斜め下方向に変更させ、焼入れ液が高周 波コイル側に逆流するのを防止し、均一に焼入れするようにしたものが提案され ている。In Japanese Utility Model Laid-Open No. 60-152668, in the above induction hardening apparatus, the injection direction of the quenching liquid is changed obliquely downward with respect to the work, and the quenching liquid flows backward to the high frequency coil side. It has been proposed to prevent this from happening and to perform uniform quenching.
【０００４】[0004]
【０００５】 上記従来の高周波焼入れ装置では、ジャケット２内で噴出した焼入れ液がワー クＷに当ってその一部がワークＷの表面を流れ落ちる。したがって、焼入れ、焼 戻し処理後ワークを取り出す際に、濡れたワークを取り扱うことになり、焼入れ 液の飛散による着衣の汚れ、作業環境の悪化を招き、また、ゴム手袋を使用して 作業しなければならなくなるので、作業能率が低下する。 本考案は、上記の問題点を解決し、焼入れ、焼戻し処理後に乾燥したワークを 取り扱うことのできる高周波焼入れ装置を提供することを目的とする。In the above-described conventional induction hardening apparatus, the hardening liquid ejected in the jacket 2 hits the work W, and a part of the hardening liquid flows down the surface of the work W. Therefore, when removing the work after quenching and tempering, the wet work must be handled, which causes stains on the clothes due to the scattering of the quenching liquid and the deterioration of the work environment. Since it becomes unnecessary, the work efficiency decreases. An object of the present invention is to solve the above problems and to provide an induction hardening apparatus capable of handling a dried work after hardening and tempering.

【課題を解決するための手段】 本考案は、加熱用の高周波コイルとその下方に設置した冷却液の噴出口を有す るジャケットの中をワークを支持して上下に往復するワーク駆動装置を設けた高 周波焼入れ装置において、前記ジャケットにエアー供給機構を付設したものであ る。Means for Solving the Problems The present invention provides a work drive device that vertically supports a work in a jacket having a heating high-frequency coil and a cooling liquid ejection port installed below the work coil. In the high frequency quenching device provided, an air supply mechanism is attached to the jacket.

熱処理が済んだ状態でエアー供給機構からジャケットにエアーを供給し、ワー クにエアーを噴射しながらワークを往復動させる。このワークの上下往復動の間 にワーク表面に着いた冷却液がエアーで吹き飛ばされ、残った液もワークの熱で 蒸発し、完全に乾いた状態になる。 Air is supplied from the air supply mechanism to the jacket after the heat treatment, and the work is reciprocated while injecting air to the work. During this vertical reciprocation of the workpiece, the cooling liquid that has reached the surface of the workpiece is blown off by the air, and the remaining liquid is also evaporated by the heat of the workpiece and becomes completely dry.

図１は、本考案の一実施例の一部を断面で示すものである。 固定した高周波コイル１の下にジャケット２を設置し、高周波コイル１は給電 装置３に接続し、ジャケット２はその内面に冷却用の焼入れ液噴出孔２ａを多数 形成して焼入れ液供給パイプ５に接続し、焼入れ液供給パイプ５には電磁開閉弁 ６が設けてある。一方、ワークＷはワーク支持具１０で支持され、ワーク駆動装 置９で高周波コイル１とジャケット２の中心に沿ってその中を回転しながら上下 方向に移動するようになっている。以上の装置は、従来の高周波焼入れ装置と同 じである。 本考案では、ジャケット２に電磁開閉弁８を配設したエアー供給パイプ７を付 設し、給電装置３，電磁開閉弁６，８及びワーク駆動装置９をＣＰＵ４でシーケ ンス制御するようにしてある。 FIG. 1 is a sectional view showing a part of an embodiment of the present invention. A jacket 2 is installed under the fixed high frequency coil 1, the high frequency coil 1 is connected to a power feeding device 3, and the jacket 2 has a large number of quenching liquid ejection holes 2a for cooling formed on the inner surface of the jacket 2 to provide a quenching liquid supply pipe 5. An electromagnetic opening / closing valve 6 is provided on the quenching liquid supply pipe 5 connected to the valve. On the other hand, the work W is supported by a work support 10 and is vertically moved while being rotated by the work drive device 9 along the centers of the high frequency coil 1 and the jacket 2. The above equipment is the same as the conventional induction hardening equipment. In the present invention, an air supply pipe 7 having an electromagnetic opening / closing valve 8 is attached to the jacket 2, and the CPU 4 controls the sequence of the power feeding device 3, the electromagnetic opening / closing valves 6, 8 and the work driving device 9. .
【０００９】 次に、この高周波焼入れ装置の作動について説明する。 例えば、カムシャフトを熱処理する場合、これをワーク支持具１０にセットし 、ワーク駆動装置９を作動させてワークＷを所定位置迄上昇させる。次に、ワー クＷの下降と同時に高周波コイル１に通電してワークＷの焼入れ部位（ピン，ジ ャーナル）の表面を急熱し、この部位がジャケット２内に移動したときにワーク Ｗを停止させ、電磁開閉弁６を開いて焼入れ液を噴射して急冷することにより焼 入れする。このときには、エアー供給パイプ７の電磁開閉弁８は閉じたままとす る。 この焼入れ工程を繰返してワークＷの焼入れ部位の全ての焼入れが済んだこと を、ワークＷが所定距離下降したことを検知して判別し、電磁開閉弁６を閉じて 焼入れ液の噴射を停止し、ワークＷを上昇させる。Next, the operation of this induction hardening apparatus will be described. For example, when heat-treating the camshaft, the camshaft is set on the work support 10 and the work drive device 9 is operated to raise the work W to a predetermined position. Next, at the same time as the work W descends, the high-frequency coil 1 is energized to rapidly heat the surface of the hardened part (pin, journal) of the work W, and when this part moves into the jacket 2, the work W is stopped. Hardening is performed by opening the solenoid on-off valve 6 and injecting quenching liquid to quench it. At this time, the electromagnetic opening / closing valve 8 of the air supply pipe 7 is kept closed. By repeating this quenching process, it is determined that the quenching of all the quenching parts of the workpiece W has been completed by detecting that the workpiece W has descended for a predetermined distance, and the electromagnetic on-off valve 6 is closed to stop the quenching liquid injection. , Raise the work W.
【００１０】 次に、焼戻し処理を行うが、この場合には、ＣＰＵ４で給電装置３を制御して 高周波コイル１によるワークＷの加熱温度を焼き戻し温度とする外は、上記の焼 入れ工程と同様とし、ワークＷの所定距離下降を検知して焼戻し完了を判別し、 電磁開閉弁６を閉じ、電磁開閉弁８を開いてジャケット２内に噴出孔２ａからエ アーを噴出させながらてワークＷを上昇させる。 この状態でワークＷを再度下降させ、ワークＷが所定距離下降したことを検知 し、電磁開閉弁８を閉じてエアーの噴射を停止する。 焼戻しの済んだワークＷは、前記の上下往復動の間に表面に着いた液がエアー で吹き飛ばされ、残った液もワークの熱で蒸発し、完全に乾いた状態となる。 したがって、乾いたワークをワーク支持具１０から取外せば良いことになる。Next, a tempering process is performed. In this case, except that the heating temperature of the work W by the high-frequency coil 1 is controlled to the tempering temperature by controlling the power feeding device 3 by the CPU 4, the above quenching process is performed. In the same manner, it is determined that the tempering is completed by detecting the fall of the work W by a predetermined distance, the electromagnetic on-off valve 6 is closed, the electromagnetic on-off valve 8 is opened, and the work W is ejected from the ejection holes 2a into the jacket 2. Raise. In this state, the work W is lowered again, it is detected that the work W is lowered by a predetermined distance, the electromagnetic on-off valve 8 is closed, and the air injection is stopped. The work W that has been tempered is blown away by the liquid that has reached the surface during the above-described vertical reciprocation, and the remaining liquid is also evaporated by the heat of the work and becomes a completely dry state. Therefore, it suffices to remove the dried work from the work support 10.
【００１１】[0011]
本考案は、熱処理後のワークの取扱を乾いた状態で行えるので、良好な作業環 境で能率良く作業できるとともに、従来の高周波焼入れ装置のジャケットにエア ー供給機構を付加させるだけなので、設備投資が少なくて済む。 Since the present invention can handle the work after the heat treatment in a dry state, the work can be performed efficiently in a good working environment, and only the air supply mechanism is added to the jacket of the conventional induction hardening equipment, so the equipment investment Is less.
