前記課題を解決するための手段として、請求項１に係る発明は、凹部とその内部に形成された畝部を有するジャケット本体に、前記凹部の開口部を封止する封止体を摩擦攪拌接合によって固定して構成される液冷ジャケットの製造方法であって、前記ジャケット本体の前記凹部の開口周縁部に形成され前記ジャケット本体の表面より下がった段差底面からなる支持面およびこの支持面と面一の前記畝部の表面に、前記封止体を載置して、前記ジャケット本体の段差側面と前記封止体の外周面を突き合わせる設置工程と、前記封止体の厚さ寸法よりも大きい長さ寸法の攪拌ピンを備えた回転ツールを、前記ジャケット本体の前記段差側面と前記封止体の外周面との突合部に沿って一周させるとともに、前記封止体の表面で前記畝部に沿って移動させて、前記封止体を前記ジャケット本体に摩擦攪拌接合してなる接合体を形成する摩擦攪拌接合工程と、前記接合体をプレス矯正する矯正工程と、を備え、前記ジャケット本体は、平面矩形形状を呈しており、 前記矯正工程では、前記封止体が下方を向くように前記接合体を配置して、前記接合体の周縁部を下側から支持し、前記ジャケット本体の対角線が交差する中央部を、前記中央部の変位量が予め試験を行って決定された数値となるまで下方に押圧してプレス矯正することにより、前記プレス矯正における押圧力が解放された際に、前記接合体がスプリングバックによって平坦な状態に戻ることを特徴とする液冷ジャケットの製造方法である。 As a means for solving the above-mentioned problems, the invention according to claim 1 is characterized in that a sealing body for sealing an opening of the recess is friction stir welded to a jacket body having a recess and a flange formed inside the recess. And a support surface comprising a step bottom surface formed at a peripheral edge of the opening of the recess of the jacket body and lowering from the surface of the jacket body, and the support surface and the surface. An installation step of placing the sealing body on the surface of the one flange part and abutting the step side surface of the jacket body and the outer peripheral surface of the sealing body, and a thickness dimension of the sealing body A rotating tool having a stirring pin having a large length is caused to make a round along the abutting portion between the stepped side surface of the jacket body and the outer peripheral surface of the sealing body, and the flange portion on the surface of the sealing body Move along Allowed by the friction stir welding to form a joined body of the sealing body formed by friction stir welding to the jacket body, and a correction step of pressing correction of the conjugate, the jacket body is flat rectangular In the straightening step, the joined body is arranged so that the sealing body faces downward, the peripheral edge of the joined body is supported from the lower side, and the diagonal lines of the jacket body intersect. When the pressing force in the press correction is released by pressing the center part downward until the displacement amount of the center part reaches a value determined by performing a test in advance, the joined body is released. Is a method for manufacturing a liquid-cooled jacket, which is returned to a flat state by springback .
このような方法によれば、摩擦攪拌接合工程の後に、接合体をプレス矯正するので、摩擦攪拌接合時に冷却する必要がない。したがって、摩擦攪拌接合作業の煩雑化を防止することができ、作業の容易化を図れる。また、回転ツールの攪拌ピンが支持面からジャケット本体内に挿入されるので、塑性化領域がジャケット本体の内部の深い部分まで入り込む。これによって、塑性化領域の熱収縮による応力をジャケット本体に分散でき、封止体の変形を抑制することができる。さらに、畝部を設けたことで、凹部が大面積の場合でも、凹部の内側部分において支持面と畝部で、ジャケット本体と封止体を接合できるので、接合体の変形を抑制できる。また、断面方向に見て接合体は、両端部で支持され中央部が下方に押圧される状態となる。さらに、接合体のスプリングバックを考慮して押圧しているので、押圧終了後に接合体を平坦にすることができる。また、中央部を集中的に押圧するので、押圧荷重が小さくて済む。 According to such a method, since the joined body is press-corrected after the friction stir welding step, it is not necessary to cool at the time of friction stir welding. Therefore, complication of the friction stir welding operation can be prevented, and the operation can be facilitated. Further, since the stirring pin of the rotary tool is inserted into the jacket body from the support surface, the plasticizing region enters into a deep portion inside the jacket body. As a result, stress due to thermal contraction in the plasticized region can be distributed to the jacket body, and deformation of the sealing body can be suppressed. Furthermore, since the jacket main body and the sealing body can be joined by the support surface and the collar at the inner portion of the recess even when the recess has a large area, the deformation of the joined body can be suppressed by providing the collar. In addition, the joined body is supported at both ends as viewed in the cross-sectional direction, and the center is pressed downward. Furthermore, since the pressing is performed in consideration of the spring back of the joined body, the joined body can be flattened after the pressing is completed. Further, since the central portion is pressed intensively, the pressing load can be reduced.
請求項２に係る発明は、凹部とその内部に形成された畝部を有するジャケット本体に、前記凹部の開口部を封止する封止体を摩擦攪拌接合によって固定して構成される液冷ジャケットの製造方法であって、 前記ジャケット本体の前記凹部の開口周縁部に形成され前記ジャケット本体の表面より下がった段差底面からなる支持面およびこの支持面と面一の前記畝部の表面に、前記封止体を載置して、前記ジャケット本体の段差側面と前記封止体の外周面を突き合わせる設置工程と、前記封止体の厚さ寸法よりも大きい長さ寸法の攪拌ピンを備えた回転ツールを、前記ジャケット本体の前記段差側面と前記封止体の外周面との突合部に沿って一周させるとともに、前記封止体の表面で前記畝部に沿って移動させて、前記封止体を前記ジャケット本体に摩擦攪拌接合してなる接合体を形成する摩擦攪拌接合工程と、前記接合体をプレス矯正する矯正工程と、を備え、前記矯正工程では、前記接合体の投影面積より大きい面積の押圧面を有する下型および上型を使用し、前記下型と前記上型との間に前記接合体の全体を位置させた状態で前記接合体をプレス矯正しており、前記下型の前記押圧面および前記上型の前記押圧面のいずれか一方が凸面にて構成され、他方が前記凸面に噛み合う凹面にて構成されており、前記矯正工程では、前記封止体が前記凹面に対向するように前記接合体を配置することを特徴とする液冷ジャケットの製造方法である。 The invention according to claim 2 is a liquid cooling jacket configured by fixing a sealing body for sealing an opening of the concave portion to a jacket main body having a concave portion and a flange portion formed therein by friction stir welding. A support surface formed of a stepped bottom surface formed at the peripheral edge of the opening of the recess of the jacket body and lowering the surface of the jacket body, and the surface of the flange portion flush with the support surface, An installation step of placing the sealing body and abutting the step side surface of the jacket main body with the outer peripheral surface of the sealing body, and a stirring pin having a length dimension larger than the thickness dimension of the sealing body The rotary tool is caused to make a round along the abutting portion between the step side surface of the jacket main body and the outer peripheral surface of the sealing body, and is moved along the flange portion on the surface of the sealing body, so that the sealing is performed. Body jacket book A friction stir welding step for forming a joined body formed by friction stir welding to a body, and a correction step for press-correcting the joined body, wherein the pressing surface has an area larger than a projected area of the joined body. The lower die and the upper die are used, and the joined body is press-corrected in a state where the whole joined body is positioned between the lower die and the upper die, and the pressing surface of the lower die And either one of the pressing surfaces of the upper mold is a convex surface, and the other is a concave surface meshing with the convex surface, and in the correction step, the sealing body faces the concave surface. It is a manufacturing method of the liquid cooling jacket characterized by arranging the above-mentioned joined object.
このような方法によれば、摩擦攪拌接合工程の後に、接合体をプレス矯正するので、摩擦攪拌接合時に冷却する必要がない。したがって、摩擦攪拌接合作業の煩雑化を防止することができ、作業の容易化を図れる。また、回転ツールの攪拌ピンが支持面からジャケット本体内に挿入されるので、塑性化領域がジャケット本体の内部の深い部分まで入り込む。これによって、塑性化領域の熱収縮による応力をジャケット本体に分散でき、封止体の変形を抑制することができる。さらに、畝部を設けたことで、凹部が大面積の場合でも、凹部の内側部分において支持面と畝部で、ジャケット本体と封止体を接合できるので、接合体の変形を抑制できる。また、接合体を安定した状態で、均一な応力で押圧することができ、プレス矯正を精度良く行うことができる。さらに、接合体のスプリングバックを考慮して、中央部が最初に反った状態よりも反対側まで押圧して変形させているので、押圧終了後にジャケット本体および封止体を平坦にすることができる。 According to such a method, since the joined body is press-corrected after the friction stir welding step, it is not necessary to cool at the time of friction stir welding. Therefore, complication of the friction stir welding operation can be prevented, and the operation can be facilitated. Further, since the stirring pin of the rotary tool is inserted into the jacket body from the support surface, the plasticizing region enters into a deep portion inside the jacket body. As a result, stress due to thermal contraction in the plasticized region can be distributed to the jacket body, and deformation of the sealing body can be suppressed. Furthermore, since the jacket main body and the sealing body can be joined by the support surface and the collar at the inner portion of the recess even when the recess has a large area, the deformation of the joined body can be suppressed by providing the collar. Further, the bonded body can be pressed with uniform stress in a stable state, and press correction can be performed with high accuracy. Furthermore, in consideration of the spring back of the joined body, since the center portion is pressed and deformed to the opposite side from the state where the center is initially warped, the jacket body and the sealing body can be flattened after the end of pressing. .
