Description

本発明は、シリンダブロックボア内局所冷却加熱装置に関する。   The present invention relates to a local cooling and heating device in a cylinder block bore.

アルミニウム合金シリンダブロックは、寸法安定化などを目的として、時効処理（Ｔ５処理）を行うことが知られている。
特許文献１には、当該時効処理として、シリンダブロックのボア内に高周波誘導加熱コイルを挿入して、高周波誘導加熱により加熱する方法が開示されている。 It is known that an aluminum alloy cylinder block is subjected to an aging treatment (T5 treatment) for the purpose of dimensional stabilization and the like.
Patent Document 1 discloses a method of inserting a high frequency induction heating coil into a bore of a cylinder block and heating by high frequency induction heating as the aging treatment.

特開２００５−９７７２３号公報JP 2005-97723 A

通常、アルミニウム合金シリンダブロックは、型により成形され、離型直後の粗材は高温となっている。一方、Ｔ５処理によって成形後の粗材の時効析出を進行させるためには、離型直後の粗材を冷却する必要がある。そのため現状は、離型直後の粗材全体を水没させて冷却することが行われている。粗材全体を水没させた場合、当該粗材全体が冷却されるため、その後Ｔ５処理時において、粗材を処理温度まで昇温するのに時間がかかるという問題があった。   Usually, the aluminum alloy cylinder block is molded by a mold, and the crude material immediately after mold release has a high temperature. On the other hand, in order to advance the aging precipitation of the coarse material after forming by the T5 treatment, it is necessary to cool the coarse material immediately after mold release. Therefore, under the present circumstances, the entire raw material immediately after mold release is submerged and cooled. When the whole roughing material is submerged, the whole roughing material is cooled, and there is a problem that it takes time to raise the temperature of the roughing material to the processing temperature at the time of T5 treatment thereafter.

本発明は上記実情に鑑みてなされたものであり、時効処理時の昇温時間を短縮可能なシリンダブロックボア内局所冷却加熱装置を提供することを目的とする。   The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a local cooling / heating device in a cylinder block bore capable of shortening a temperature rising time at the time of aging treatment.

本発明によれば、時効処理時の昇温時間を短縮可能なシリンダブロックボア内局所冷却加熱装置を提供することができる。   According to the present invention, it is possible to provide a local cooling / heating device in a cylinder block bore capable of shortening the temperature rising time during the aging treatment.

本発明のシリンダブロックボア内局所冷却加熱装置は、少なくとも一つの耐熱バルーンを有し、当該耐熱バルーン内に、冷却水配管と、誘導コイルとが配置されたことを特徴とする。
本発明のシリンダブロックボア内局所冷却加熱装置によれば、時効処理が必要なボア部表面付近のみを局所的に冷却し、また、加熱できるため、離型直後で高温となっている成形後の粗材全体の温度の低下を抑えながらボア部を局所的に冷却することができ、その結果、その後の時効処理のための昇温時間を短縮することができる。
以下このような本発明のシリンダブロックボア内局所冷却加熱装置の実施形態について図を参照して説明する。 The local cooling and heating device in a cylinder block bore of the present invention has at least one heat resistant balloon, and a cooling water pipe and an induction coil are disposed in the heat resistant balloon.
According to the local cooling and heating device in the cylinder block bore of the present invention, since only the vicinity of the bore surface which requires an aging treatment can be locally cooled and heated, it is possible to heat immediately after mold release. It is possible to locally cool the bore portion while suppressing a decrease in the temperature of the entire coarse material, and as a result, it is possible to shorten the temperature rise time for the subsequent aging treatment.
Hereinafter, an embodiment of such a local cooling / heating device in a cylinder block bore of the present invention will be described with reference to the drawings.

図１の（Ａ）は、本発明のシリンダブロックボア内局所冷却加熱装置の一例を示す模式図であり、図１の（Ｂ）は耐熱バルーン１の模式的な断面図である。図１の例では、シリンダブロックボア内局所冷却加熱装置１０は、シリンダブロック５内に配置された状態である。なお、図１の断面は、後述する図２の例に示されるシリンダブロック５のボア部１１を通る断面である。
図１（Ａ）の例に示されるとおり、本発明のシリンダブロックボア内局所冷却加熱装置１０は、少なくとも一つの耐熱バルーン１を有し、当該耐熱バルーン１内に、冷却水配管３と、誘導コイル４とが配置されている。本発明において耐熱バルーンの数は、製造するシリンダブロックのボア部の数に対応するものであり、特に限定されるものではない。耐熱バルーン１が複数ある場合、複数ある耐熱バルーン１は、通常、支持体２を介して接続される。支持体２を介することにより、耐熱バルーンの相対的な位置関係が固定される。支持体２は、一例として、筒状の支持体であって、内部に耐熱バルーン１内の冷却水配管３と接続された配管と、誘導コイル４に接続された導線と、排水９のための配管とが挿通されている。 FIG. 1A is a schematic view showing an example of a local cooling and heating device in a cylinder block bore according to the present invention, and FIG. 1B is a schematic cross-sectional view of a heat resistant balloon 1. In the example of FIG. 1, the cylinder block bore local cooling heating device 10 is in a state of being disposed in the cylinder block 5. In addition, the cross section of FIG. 1 is a cross section which passes along the bore part 11 of the cylinder block 5 shown by the example of FIG. 2 mentioned later.
As shown in the example of FIG. 1 (A), the cylinder block bore local cooling and heating device 10 of the present invention has at least one heat resistant balloon 1, and in the heat resistant balloon 1, a cooling water pipe 3 and an induction A coil 4 is disposed. In the present invention, the number of heat-resistant balloons corresponds to the number of bores of the cylinder block to be manufactured, and is not particularly limited. When there are a plurality of heat resistant balloons 1, the plurality of heat resistant balloons 1 are usually connected via the support 2. By means of the support 2, the relative positional relationship of the heat-resistant balloon is fixed. The support 2 is, for example, a tubular support, and a pipe connected to the cooling water pipe 3 in the heat resistant balloon 1, a lead connected to the induction coil 4, and drainage 9 inside. The piping is inserted.

次いで、図１（Ｂ）を参照して耐熱バルーン１を説明する。耐熱バルーン１は少なくともＴ５処理温度以上の温度に対する耐熱性を有し、内圧により膨張する性質を有する。耐熱バルーン１内には、冷却水配管３と、誘導コイル４とが配置されている。冷却水配管３は耐熱バルーン１内に冷却水８を導入するためのものであり、配管の材質は特に限定されないが、一例として、非金属性材料とすることができる。また、誘導コイル４はボア部の内壁を誘導加熱するものである。   Next, the heat-resistant balloon 1 will be described with reference to FIG. 1 (B). The heat resistant balloon 1 has heat resistance to a temperature of at least T5 processing temperature and has a property of being expanded by the internal pressure. A cooling water pipe 3 and an induction coil 4 are disposed in the heat resistant balloon 1. The cooling water pipe 3 is for introducing the cooling water 8 into the heat resistant balloon 1 and the material of the pipe is not particularly limited, but can be made of a non-metallic material as an example. The induction coil 4 is for inductively heating the inner wall of the bore portion.

また、図２は、シリンダブロックの一例を示す模式的な斜視図である。図２の例に示されるとおり、シリンダブロック５はボア部１１を有する。図２の例ではシリンダブロック５は４つのボア部１１を有するが、ボア部１１の数は特に限定されるものではなく、用途等に応じて設計されるものである。ボア部１１の内壁は、ライナー７を有する（図１（Ｂ）参照）。本発明においてシリンダブロック５のその他の構成は、特に限定されず、シリンダブロックとして公知の構成を適宜選択して用いることができる。   FIG. 2 is a schematic perspective view showing an example of the cylinder block. As shown in the example of FIG. 2, the cylinder block 5 has a bore 11. Although the cylinder block 5 has four bores 11 in the example of FIG. 2, the number of bores 11 is not particularly limited, and is designed according to the application and the like. The inner wall of the bore portion 11 has a liner 7 (see FIG. 1 (B)). In the present invention, the other configuration of the cylinder block 5 is not particularly limited, and a known configuration as a cylinder block can be appropriately selected and used.

次に、図３及び図４を参照して、本発明のシリンダブロックボア内局所冷却加熱装置の使用方法について説明する。
まず、成形されたシリンダブロック５を離型する（Ｓ１）。このとき離型直後の粗材は高温となっている。次いで、本発明のシリンダブロックボア内局所冷却加熱装置の耐熱バルーン１をボア部１１内に挿入する（Ｓ２）。図３（Ａ）に示されるように、シリンダブロックボア内局所冷却加熱装置１０の耐熱バルーン１の位置にあわせてシリンダブロック５のボア部１１を配置すれば容易に挿入することができる。挿入後の状態を図３（Ｂ）に示す。次いで、冷却水配管３を通じて冷却水８を流す（Ｓ３）。このとき耐熱バルーン１は冷却水８により膨張しボア部１１の内壁に密着する（Ｓ４）。これにより、耐熱バルーン１を介してボア部の内壁と冷却水８とが熱交換が促進されて、ボア部の内壁が冷却される。また温度の上昇した排水９は、耐熱バルーン１の上部などから排出される。ボア部内壁の冷却後、誘導コイル４に電流を流す（Ｓ５）。これにより、ライナー７が誘導加熱される（Ｓ６）。ライナーが目的温度に到達後、誘導コイルへの通電を停止し（Ｓ７）、冷却水の循環を停止する。最後に本発明のシリンダブロックボア内局所冷却加熱装置をボア内から引き抜くことで、時効処理が完了する（Ｓ８）。このように本発明のシリンダブロックボア内局所冷却加熱装置によれば、ボア内を局所的に冷却し加熱することができるため、時効処理時の昇温時間を短縮することが可能である。 Next, with reference to FIG. 3 and FIG. 4, a method of using the local cooling and heating device within the cylinder block of the present invention will be described.
First, the molded cylinder block 5 is released (S1). At this time, the coarse material immediately after mold release is at a high temperature. Next, the heat-resistant balloon 1 of the local cooling and heating device in the cylinder block bore of the present invention is inserted into the bore portion 11 (S2). As shown in FIG. 3A, the bore portion 11 of the cylinder block 5 can be easily inserted by arranging the heat resistant balloon 1 of the local cooling and heating device 10 in the cylinder block bore according to the position of the heat resistant balloon 1. The state after insertion is shown in FIG. 3 (B). Next, the cooling water 8 is allowed to flow through the cooling water pipe 3 (S3). At this time, the heat resistant balloon 1 is expanded by the cooling water 8 and closely attached to the inner wall of the bore portion 11 (S4). As a result, heat exchange between the inner wall of the bore portion and the cooling water 8 is promoted via the heat resistant balloon 1, and the inner wall of the bore portion is cooled. The temperature-increased drainage 9 is discharged from the upper portion of the heat-resistant balloon 1 or the like. After cooling the inner wall of the bore portion, a current is supplied to the induction coil 4 (S5). Thereby, the liner 7 is inductively heated (S6). After the liner reaches the target temperature, energization of the induction coil is stopped (S7), and circulation of cooling water is stopped. Finally, the aging process is completed by pulling out the local cooling and heating device in the cylinder block bore of the present invention from the bore (S8). As described above, according to the cylinder block bore local cooling and heating device of the present invention, since the inside of the bore can be locally cooled and heated, it is possible to shorten the temperature rising time during the aging treatment.
