Description

本発明は、曲げ部の稜線に断面Ｓ字状の屈曲部を形成して成るハット状のダイクエンチ加工製品とその製造方法及び製造装置に関するものである。   The present invention relates to a hat-shaped die quench processed product formed by forming a bent portion having an S-shaped cross section on a ridge line of a bent portion, a manufacturing method thereof, and a manufacturing apparatus.

例えば自動車部品は、鋼板等の金属板材（ブランク材）をプレス成形することによって得られるが、近年、燃費や安全性の向上という目的のため、自動車部品には軽量化や高強度化が強く求められている。
時に板厚が部分的に減少し、その部分の強度や剛性が低下するという問題がある。 For example, automobile parts can be obtained by press-molding a metal plate material (blank material) such as a steel plate. Recently, for the purpose of improving fuel efficiency and safety, automobile parts are strongly required to be lighter and stronger. It has been.
There is a problem that the plate thickness is partially reduced and the strength and rigidity of the portion are sometimes lowered.

そこで、自動車部品の高強度化には、素材板厚を厚くしたり、補強したい部分に別部品を溶接する方法が従来から採用されている。   Therefore, in order to increase the strength of automobile parts, a method of increasing the thickness of the material plate or welding another part to a portion to be reinforced is conventionally employed.

又、特許文献１には、長手方向に連続した断面がＴ字形状である凸部を有する成形品を超塑性金属材料を用いて製造する方法と装置が提案されている。

JP 2007-038255 A

しかしながら、従来のように高強度化のために素材板厚を厚くすると、製品の強度は向上する反面、製品重量が増加するとともに、コストアップを免れないという問題が発生する。又、補強したい部分に別部品を溶接する方法では、製造工程に溶接工程が追加されるために製造工数が増えて製造コストがアップするという問題がある。   However, if the thickness of the material plate is increased to increase the strength as in the conventional case, the strength of the product is improved, but the weight of the product is increased, and there is a problem that the cost cannot be increased. Further, in the method of welding another part to the part to be reinforced, there is a problem that the manufacturing process increases and the manufacturing cost increases because a welding process is added to the manufacturing process.

更に、特許文献１に記載された方法及び装置によって製造される成形品は、素材が超塑性金属材料であるために高強度化には限界があり、高い強度を期待することができないという問題がある。   Furthermore, the molded product manufactured by the method and apparatus described in Patent Document 1 has a problem that the strength cannot be increased because the material is a superplastic metal material, and high strength cannot be expected. is there.

本発明は上記問題に鑑みてなされたもので、その目的とする処は、曲げ部の稜線に断面Ｓ字状の屈曲部が形成された軽量で高強度化なダイクエンチ加工製品とこれを生産性良く且つ低コストで得ることができる製造方法及び製造装置を提供することにある。   The present invention has been made in view of the above problems, and the object of the process is a lightweight and high-strength die quench processed product in which a bent portion having an S-shaped cross section is formed on the ridge line of the bent portion, and productivity thereof. It is an object of the present invention to provide a manufacturing method and a manufacturing apparatus which can be obtained at a good cost.

上記目的を達成するため、請求項１記載の発明は、ダイクエンチ加工によってハット形状に成形された金属製のダイクエンチ加工製品の曲げ部の稜線に断面Ｓ字状の屈曲部を形成したことを特徴とする。   In order to achieve the above object, the invention described in claim 1 is characterized in that a bent portion having an S-shaped cross section is formed on the ridge line of the bent portion of a metal die quench processed product formed into a hat shape by die quench processing. To do.

請求項２記載の発明は、ダイクエンチ加工によって曲げ部の稜線に断面Ｓ字状の屈曲部が形成されたハット形状のダイクエンチ加工製品を製造する方法として、加熱された金属板の曲げ部を除く平坦部を上下のプレス型で挟み込んでプレス成形することによって曲げ部を形成し、該曲げ部をプレス型に接触させないで高温状態を維持したまま、該曲げ部を上下のプレス型間に形成された空間内で圧縮して曲げ部の稜線に断面Ｓ字状の屈曲部を形成することを特徴とする。   The invention according to claim 2 is a method for producing a hat-shaped die quench processed product in which a bent portion having an S-shaped cross section is formed on the ridge line of the bent portion by die quenching, and is a flat method excluding a bent portion of a heated metal plate. The bent part was formed by sandwiching the part between the upper and lower press dies and press forming, and the bent part was formed between the upper and lower press dies while maintaining the high temperature state without contacting the bent part with the press dies. It is characterized in that a bent portion having an S-shaped cross section is formed on the ridge line of the bent portion by compressing in the space.

請求項３記載の発明は、固定パンチと可動パンチを有する金型及び固定ダイと可動ダイを有する金型を備えたプレス型によるダイクエンチ加工によって曲げ部の稜線に断面Ｓ字状の屈曲部が形成されたハット形状のダイクエンチ加工製品を製造する装置において、加熱された金属板の曲げ部を除く平坦部を前記プレス型の上型と下型によって挟み込んでプレス成形して曲げたときに該金属板の曲げ部がプレス型に接触しないよう上型と下型の間に空間を形成したことを特徴とする。   According to a third aspect of the present invention, a bent portion having an S-shaped cross section is formed on the ridge line of the bent portion by die quenching using a die having a fixed punch and a movable punch and a press die having a fixed die and a die having a movable die. In the apparatus for producing a hat-shaped die quench processed product, when the flat portion excluding the bent portion of the heated metal plate is sandwiched between the upper die and the lower die of the press die and press-formed and bent, the metal plate A feature is that a space is formed between the upper die and the lower die so that the bent portion of the upper die does not contact the press die.

本発明に係るダイクエンチ加工製品においては、曲げ部の稜線に断面Ｓ字状の屈曲部が形成されているため、成形時に曲げ部の強度と剛性が断面Ｓ字状の屈曲部によって高められ、ダイクエンチ加工製品の軽量化と高強度化が図られる。   In the die-quenched processed product according to the present invention, since a bent portion having an S-shaped cross section is formed on the ridge line of the bent portion, the strength and rigidity of the bent portion are enhanced by the bent portion having the S-shaped cross section during molding. Reduced weight and strength of processed products.

又、本発明に係るダイクエンチ加工製品の製造方法及び製造装置によれば、加熱された金属板の曲げ部を除く平坦部を上下のプレス型で挟み込んでプレス成形することによって曲げ部を形成し、該曲げ部をプレス型に接触させないで高温状態を維持したまま、該曲げ部を上下のプレス型間に形成された空間内で圧縮して曲げ部の稜線に断面Ｓ字状の屈曲部を形成するようにしたため、プレス工程の１工程だけで成形品の曲げ部の稜線に断面Ｓ字状の屈曲部が形成され、この屈曲部によって曲げ部の強度と剛性が高められる。この結果、軽量で高強度なダイクエンチ加工製品を生産性良く且つ低コストで製造することができる。   Moreover, according to the manufacturing method and the manufacturing apparatus of the die quench processed product according to the present invention, the bent portion is formed by sandwiching the flat portion excluding the bent portion of the heated metal plate with the upper and lower press dies and press-molding. The bent portion is compressed in the space formed between the upper and lower press dies while keeping the high temperature state without contacting the bent portion with the press die to form a bent portion having an S-shaped cross section at the ridge line of the bent portion. Therefore, a bent portion having an S-shaped cross section is formed on the ridge line of the bent portion of the molded article in only one step of the pressing step, and the strength and rigidity of the bent portion are enhanced by this bent portion. As a result, a lightweight and high-strength die quench processed product can be manufactured with high productivity and at low cost.

尚、加熱された金属板の曲げ部を除く平坦部を上下のプレス型で挟み込んでプレス成形する際、金属板の曲げ部を除く平坦部は、金型によって急冷されるために焼き入れされて硬化される。又、当初は金型に接触しないで高温状態を維持している金属板の曲げ部は、その後に圧縮されて断面Ｓ字状に屈曲すると金型に接触して冷却されるため、焼き入れによって硬化する。   In addition, when the flat part excluding the bent part of the heated metal plate is sandwiched between the upper and lower press dies, the flat part excluding the bent part of the metal plate is quenched because it is quenched by the mold. Cured. In addition, the bent portion of the metal plate that is initially kept at a high temperature without contacting the mold is cooled by contact with the mold when it is subsequently compressed and bent into a S-shaped cross section. Harden.

又、本発明では、高温時に柔らかい金属板の材料特性を利用して、金属板の補強したい曲げ部を高温状態を維持したままプレス型の空間において該曲げ部を圧縮して稜線に断面Ｓ字状の屈曲部を部分的に形成するようにしたため、該屈曲部が容易に形成できる。   Further, in the present invention, by utilizing the material characteristics of a soft metal plate at a high temperature, the bent portion to be reinforced of the metal plate is compressed in the press mold space while maintaining the high temperature state, and the ridge line is formed with an S-shaped cross section. Since the bent portion is partially formed, the bent portion can be easily formed.

以下に本発明の実施の形態を添付図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings.

図１〜図４は本発明に係るダイクエンチ加工製品の製造方法をその工程順に示す製造装置の断面図、図５は図４のＡ部拡大詳細図、図６は本発明に係るダイクエンチ加工製品の斜視図、図７は同ダイクエンチ加工製品の横断面図である。   1 to 4 are cross-sectional views of a manufacturing apparatus showing a method of manufacturing a die quench processed product according to the present invention in the order of the steps, FIG. 5 is an enlarged detail view of part A of FIG. 4, and FIG. FIG. 7 is a cross-sectional view of the die-quenched product.

先ず、本発明に係るダイクエンチ加工製品の製造装置の基本構成を図１〜図４に基づいて説明すると、図中、１，２はプレス型を構成する上型と下型であって、上型１は、図の紙面垂直方向に長い固定パンチ１１と、該固定パンチ１１の中心部に上下動可能に嵌合保持された可動パンチ１２とで構成されている。ここで、可動パンチ１２は、図の紙面垂直方向に長いブロック状の金型であって、固定パンチ１１を貫通するクッションピン１３によって上下動可能に保持されている。   First, the basic configuration of a die quench processed product manufacturing apparatus according to the present invention will be described with reference to FIGS. 1 to 4. In the figure, reference numerals 1 and 2 denote an upper die and a lower die constituting a press die, 1 is composed of a fixed punch 11 that is long in the direction perpendicular to the paper surface of the drawing, and a movable punch 12 that is fitted and held in the center of the fixed punch 11 so as to be movable up and down. Here, the movable punch 12 is a block-shaped mold that is long in the direction perpendicular to the drawing sheet, and is held by a cushion pin 13 that passes through the fixed punch 11 so as to be movable up and down.

又、下型２は、図の紙面垂直方向に長い固定ダイ２１と、同じく図の紙面垂直方向に長い可動ダイ２２とで構成されており、可動ダイ２２は、固体ダイ２１に上下動可能に嵌合されており、固定ダイ２１を貫通するクッションピン２３によって上下動可能に保持されている。   The lower die 2 is composed of a fixed die 21 that is long in the direction perpendicular to the paper surface of the figure, and a movable die 22 that is also long in the direction perpendicular to the paper surface of the figure. It is fitted and held by a cushion pin 23 penetrating the fixed die 21 so as to be movable up and down.

又、固定パンチ１１、可動パンチ１２、固定ダイ２１及び可動ダイ２２の加工面の近くには図示しない複数の冷却配管が配設され、これらの冷却配管内に冷却水や冷媒等の冷却媒体を流して上型１と下型２の表面を冷却し、これらの上型１と下型２に接触した金属板Ｗ１を急冷することができるため、その強度と剛性が一層高められるとともに、連続加工が可能となる。   In addition, a plurality of cooling pipes (not shown) are provided near the processing surfaces of the fixed punch 11, the movable punch 12, the fixed die 21, and the movable die 22, and a cooling medium such as cooling water or refrigerant is placed in these cooling pipes. Since the surface of the upper mold 1 and the lower mold 2 can be cooled to cool the metal plate W1 in contact with the upper mold 1 and the lower mold 2, the strength and rigidity can be further enhanced and continuous processing can be performed. Is possible.

ところで、以上のように構成された上型１と下型２は、加圧手段である不図示のプレス機によって駆動されて所要のダイクエンチ加工に供せられる。   By the way, the upper mold 1 and the lower mold 2 configured as described above are driven by a press machine (not shown) which is a pressurizing unit and subjected to a required die quench process.

次に、以上のように構成された製造装置を用いて図６に示すようなハット状のダイクエンチ加工製品Ｗを製造する方法を図１〜図５に従って説明する。   Next, a method of manufacturing a hat-shaped die quench processed product W as shown in FIG. 6 using the manufacturing apparatus configured as described above will be described with reference to FIGS.

ダイクエンチ加工に際しては、所定温度に加熱された金属板（ブランク材）Ｗ１が下型２の可動ダイ２２上に水平にセットされており、ダイクエンチ加工が開始されると、図１に示すように、下型２の上方に位置している上型１が下降し、下型２の可動ダイ２２上にセットされた金属板Ｗ１が上型１と下型２によってプレス加工される。ここで、金属板Ｗ１には鋼板が使用され、この鋼板は９００℃〜９５０℃に加熱される。   At the time of die quenching, a metal plate (blank material) W1 heated to a predetermined temperature is set horizontally on the movable die 22 of the lower mold 2, and when die quenching is started, as shown in FIG. The upper die 1 located above the lower die 2 is lowered, and the metal plate W1 set on the movable die 22 of the lower die 2 is pressed by the upper die 1 and the lower die 2. Here, a steel plate is used for the metal plate W1, and this steel plate is heated to 900 ° C. to 950 ° C.

そして、上型１の固定パンチ１１と可動パンチ１２の位置関係を保持したまま、該上型１が更に下動し、図２に示すように、上型１の固定パンチ１１と可動パンチ１２が下型２の可動ダイ２２と固定ダイ２１にそれぞれ当接すると、金属板Ｗ１は横断面Ｕ字状のハット形状（チャンネル形状）に成形されるとともに、上型１と下型２との間には図２の紙面垂直方向に長い空間Ｓが上型１の可動パンチ１２の両側に形成される。この状態では、加熱された金属板Ｗ１の曲げ部Ｗａを除く左右の側面部Ｗｂと左右のフランジ部Ｗｃ及び天面部（図では底面部）Ｗｄが上型１と下型２で挟み込まれて冷却され、これらの側面部Ｗｂとフランジ部Ｗｃ及び天面部Ｅｄ（平坦部）が焼入されて硬化する。   Then, while maintaining the positional relationship between the fixed punch 11 and the movable punch 12 of the upper mold 1, the upper mold 1 further moves downward, and as shown in FIG. 2, the fixed punch 11 and the movable punch 12 of the upper mold 1 are moved. When the movable die 22 and the fixed die 21 of the lower die 2 are brought into contact with each other, the metal plate W1 is formed into a hat shape (channel shape) having a U-shaped cross section, and between the upper die 1 and the lower die 2. In FIG. 2, spaces S that are long in the direction perpendicular to the paper surface are formed on both sides of the movable punch 12 of the upper die 1. In this state, the left and right side surfaces Wb except the bent portion Wa of the heated metal plate W1, the left and right flange portions Wc, and the top surface portion (bottom surface portion in the figure) Wd are sandwiched between the upper mold 1 and the lower mold 2 and cooled. The side surface portion Wb, the flange portion Wc, and the top surface portion Ed (flat portion) are hardened by being hardened.

これに対して、金属板Ｗ１の左右の曲げ部Ｗａは、上型１と下型２間に形成された前記空間Ｓに臨んで上型１にも下型２にも接触しないために冷却されず、高温状態を維持する。   On the other hand, the left and right bent portions Wa of the metal plate W1 are cooled because they face the space S formed between the upper mold 1 and the lower mold 2 and do not contact the upper mold 1 and the lower mold 2. Without maintaining a high temperature state.

次に、図２に示す状態から、上型１を更に下動させると、該上型１の可動パンチ１２は下型２の固定ダイ２１に当接して不動であるため、固定パンチ１１のみが下型２の可動ダイ２２を押圧しながら該可動ダイ２２と共に下降し、金属板Ｗ１の曲げ部Ｗａが空間Ｓ内で圧縮される。そして、上型１の固定パンチ１１が更に下動して図４に示すように下型２の固定ダイ２１に当接すると、図５に詳細に示すように、金属板Ｗ１の曲げ部Ｗａは更に圧縮されて屈曲し、該曲げ部Ｗａの稜線に断面Ｓ字状の屈曲部ａが形成される。このように、金属板Ｗ１の曲げ部Ｗａの稜線に断面Ｓ字状の屈曲部ａが形成されると、この屈曲部ａは上型１の固定パンチ１１と下型２の可動ダイ２２に接触して冷却されるため、この屈曲部ａが焼き入れされて硬化する。   Next, when the upper die 1 is further moved downward from the state shown in FIG. 2, the movable punch 12 of the upper die 1 is in contact with the fixed die 21 of the lower die 2 and is not moved. While pressing the movable die 22 of the lower mold 2, the lower die 2 descends with the movable die 22, and the bent portion Wa of the metal plate W <b> 1 is compressed in the space S. Then, when the fixed punch 11 of the upper die 1 is further moved downward and comes into contact with the fixed die 21 of the lower die 2 as shown in FIG. 4, the bent portion Wa of the metal plate W1 becomes as shown in detail in FIG. Further, the bent portion is compressed and bent, and a bent portion a having an S-shaped cross section is formed at the ridgeline of the bent portion Wa. When the bent portion a having the S-shaped cross section is formed on the ridge line of the bent portion Wa of the metal plate W1, the bent portion a contacts the fixed punch 11 of the upper die 1 and the movable die 22 of the lower die 2. Then, the bent portion a is quenched and hardened.

以上の工程を経て図６及び図７に示すようなハット状（チャンネル状）のダイクエンチ加工製品Ｗが製造されるが、その底部の左右の曲げ部Ｗａの稜線に断面Ｓ字状の屈曲部ａが長手方向に沿って連続的に形成され、その部分の強度と剛性が屈曲部ａによって高められる。   A hat-shaped (channel-shaped) die-quenched product W as shown in FIGS. 6 and 7 is manufactured through the above steps, and a bent portion a having an S-shaped cross section is formed on the ridgeline of the left and right bent portions Wa. Are continuously formed along the longitudinal direction, and the strength and rigidity of the portion are enhanced by the bent portion a.

ところで、ダイクエンチ加工によってハット形状に成形された成形品の曲げ部は板厚が減少し、その部分の強度や剛性が低下するが、本発明に係るダイクエンチ加工製品Ｗにおいては、曲げ部Ｗａの稜線に断面Ｓ字状の屈曲部ａが形成されているため、成形時に板厚が減少する曲げ部Ｗａの強度と剛性が断面Ｓ字状の屈曲部ａによって高められ、ダイクエンチ加工製品Ｗの軽量化と高強度化が図られる。尚、ダイクエンチ加工製品Ｗの曲げ部Ｗａの稜線に屈曲部ａを形成すると、屈曲部ａがない成形品の約１．５倍の強度が得られた。   By the way, the bent portion of the molded product formed into a hat shape by die quench processing has a reduced plate thickness, and the strength and rigidity of the portion are reduced. However, in the die quench processed product W according to the present invention, the ridge line of the bent portion Wa Since the bent portion a having a S-shaped cross section is formed in the bent portion Wa, the strength and rigidity of the bent portion Wa whose thickness is reduced during molding is increased by the bent portion a having the S-shaped cross section, thereby reducing the weight of the die quench processed product W. Strengthening is achieved. In addition, when the bending part a was formed in the ridgeline of the bending part Wa of the die quench processed product W, about 1.5 times the intensity | strength of the molded product without the bending part a was obtained.

又、本発明に係るダイクエンチ加工製品Ｗの製造方法及び製造装置によれば、加熱された金属板Ｗ１の曲げ部Ｗａを除く側面部Ｗｂとフランジ部Ｗｃ及び天面部Ｅｄ（平坦部）を上型１と下型２で挟み込んでプレス成形することによって曲げ部Ｗａを形成し、該曲げ部Ｗａを上型１と下型２に接触させないで高温状態を維持したまま、該曲げ部Ｗａを上型１と下型２の間に形成された空間Ｓ内で圧縮して曲げ部Ｗａの稜線に断面Ｓ字状の屈曲部ａを形成するようにしたため、プレス工程の１工程だけでダイクエンチ加工製品Ｗの曲げ部Ｗａの稜線に断面Ｓ字状の屈曲部ａが形成され、この屈曲部ａによって曲げ部Ｗａの強度と剛性が高められる。この結果、図６及び図７に示すような軽量で高強度なダイクエンチ加工製品Ｗを生産性良く且つ低コストで製造することができる。   Moreover, according to the manufacturing method and manufacturing apparatus of the die quench processed product W which concerns on this invention, the side part Wb except the bending part Wa of the heated metal plate W1, the flange part Wc, and the top | upper surface part Ed (flat part) are upper mold | types. The bent portion Wa is formed by sandwiching between 1 and the lower mold 2 and press forming, and the bent portion Wa is maintained in the upper mold while maintaining the high temperature state without contacting the bent portion Wa with the upper mold 1 and the lower mold 2. Since the bent portion a having a S-shaped cross section is formed in the ridgeline of the bent portion Wa by compressing in the space S formed between the first die 2 and the lower mold 2, the die quench processed product W is formed in only one step of the pressing step. A bent portion a having an S-shaped cross section is formed on the ridge line of the bent portion Wa, and the strength and rigidity of the bent portion Wa are enhanced by the bent portion a. As a result, a lightweight and high-strength die quench processed product W as shown in FIGS. 6 and 7 can be manufactured with high productivity and at low cost.

そして、本発明では、高温時に柔らかい金属板Ｗ１の材料特性を利用して、金属板Ｗ１の補強したい曲げ部Ｗａを高温状態を維持したまま上型１と下型２間の空間Ｓにおいて該曲げ部Ｗａを圧縮して稜線に断面Ｓ字状の屈曲部ａを部分的に形成するようにしたため、該屈曲部ａが容易に形成される。   In the present invention, by utilizing the material characteristics of the soft metal plate W1 at high temperatures, the bending portion Wa to be reinforced of the metal plate W1 is bent in the space S between the upper die 1 and the lower die 2 while maintaining the high temperature state. Since the portion Wa is compressed to partially form the bent portion a having an S-shaped cross section on the ridgeline, the bent portion a is easily formed.
