Description

本発明は、熱間プレス加工方法および熱間プレス加工装置に関する。   The present invention relates to a hot press working method and a hot press working apparatus.

熱間プレス加工とは、プレス成形前にワークを高温に加熱し、加熱後金型で成形しながら型冷却して焼き入れを行う工法である（例えば下記特許文献１参照）。焼き入れ後のワークの硬度は、Ｈｖ４５０程度に上昇する。そのため、ワークに穴加工が必要な場合には、穴加工を焼き入れ後に行うと工具の損傷などの恐れがあることから、焼き入れ前（加熱前）に穴加工を実施することが望ましい。   Hot press working is a method of heating a workpiece to a high temperature before press forming and then quenching the mold while forming with a mold after heating (for example, see Patent Document 1 below). The hardness of the workpiece after quenching increases to about Hv450. For this reason, when drilling is required in the workpiece, it is desirable to perform drilling before quenching (before heating) because there is a risk of tool damage if drilling is performed after quenching.

焼き入れ前に加工した穴は、プレス成形時に生じる材料流入の影響を受けない部位（ポンチに対応する部位など）については、熱間プレス成形後も変形はほとんど発生せず、部品性能を満足した穴径を確保することができる。
特開２００２−１０２９７９号公報 Holes machined before quenching were not affected by material inflow that occurred during press molding (parts corresponding to punches, etc.), and almost no deformation occurred after hot press molding, satisfying part performance. Hole diameter can be ensured.
JP 2002-102979 A

しかしながら、プレス成形時に材料流入の影響を受ける部位（例えば縦壁や稜線付近で成形量が多い部位）に位置する穴の場合は、プレス成形時に穴周辺に張力が働き、穴形状が変形してしまい、部品として満足できない状態が発生してしまう。これは、高温に加熱された材料は、引張り強度が低下しているために、変形しやすくなっていることが原因である。   However, in the case of a hole located in a part that is affected by material inflow during press molding (for example, a part where the molding amount is large near the vertical wall or ridgeline), tension acts on the periphery of the hole during press molding and the hole shape is deformed. As a result, an unsatisfactory state occurs as a part. This is because the material heated to a high temperature is easily deformed because the tensile strength is lowered.

そのため、穴径などの精度の必要な穴で、プレス成形時に材料流入の影響を受ける部位に位置する穴の加工は、熱間プレス成形後に実施せざるを得ず、このような場合には、前述したように工具の損傷を伴うことになる。   Therefore, in holes that require accuracy such as hole diameter, the processing of holes located in the parts affected by the material inflow during press molding must be carried out after hot press molding. As described above, the tool is damaged.

そこで、本発明は、熱間プレス成形前に、プレス成形時に材料流入の影響を受ける部位に位置する穴の加工を行っても、プレス成形時での穴の変形を防止することを目的としている。   Therefore, the present invention has an object of preventing deformation of a hole during press molding even when a hole located at a portion affected by material inflow during press molding is processed before hot press molding. .

本発明は、加熱したワークを熱間プレス加工手段に搬送するまでの間に、前記加熱前に加工した穴の周辺部を局所的に冷却して焼き入れを行い、この焼き入れ後に、前記ワークを前記熱間プレス加工手段にて熱間プレス加工を行うことを最も主要な特徴とする。   The present invention performs quenching by locally cooling the peripheral portion of the hole processed before the heating until the heated workpiece is conveyed to the hot press working means, and after the quenching, the workpiece The main feature is that hot pressing is performed by the hot pressing means.

本発明によれば、加熱したワークを熱間プレス加工手段に搬送するまでの間に、加熱前に加工した穴の周辺部を局所的に冷却させて焼き入れを行うようにしたので、その後ワークに対して熱間プレス加工を行っても、このプレス成形時に材料流入の影響を受ける部位に位置する穴の変形を防止することができる。   According to the present invention, the periphery of the hole processed before heating is locally cooled and quenched before the heated work is conveyed to the hot press working means. However, even if hot pressing is performed, deformation of a hole located at a portion affected by material inflow during press forming can be prevented.

前記した冷却ブロック４７，４９内には、図５に拡大して示すように、ワークＷを保持した状態で、その穴Ｈの周囲を囲むような位置に、冷却用パイプ５１，５３を埋め込んでいる。冷却ブロック４７，４９内の各冷却用パイプ５１，５３の両端は、冷却ブロック４７，４９内からその外部に、入口および出口パイプ５１ａおよび５１ｂ，入口および出口パイプ５３ａおよび５３ｂとしてそれぞれ引き出し、図示しない冷却装置に接続して冷却水などの冷却媒体を循環させる。   In the cooling blocks 47 and 49, as shown in an enlarged view in FIG. 5, the cooling pipes 51 and 53 are embedded in a position surrounding the hole H while holding the workpiece W. Yes. Both ends of the cooling pipes 51 and 53 in the cooling blocks 47 and 49 are drawn out from the cooling blocks 47 and 49 to the outside as inlet and outlet pipes 51a and 51b and inlet and outlet pipes 53a and 53b, respectively, and are not shown. A cooling medium such as cooling water is circulated by connecting to a cooling device.

次に作用を説明する。まず、図１に示すように、ワーク投入用ロボット３により、ワーク格納部１に格納してあるワークＷを把持して加熱炉５に投入し、ワークＷの加熱を行う。このワークＷは、前述したように、加熱炉５での加熱前に図２に示すような穴Ｈをあらかじめ加工してある。   Next, the operation will be described. First, as shown in FIG. 1, the workpiece loading robot 3 grips the workpiece W stored in the workpiece storage unit 1 and puts it into the heating furnace 5 to heat the workpiece W. As described above, the workpiece W has holes H as shown in FIG. 2 processed in advance before heating in the heating furnace 5.

加熱後の加熱炉５内のワークＷは、ワーク搬送用ロボット７により把持して熱間プレス成形機９に搬送する。   The heated workpiece W in the heating furnace 5 is held by the workpiece transfer robot 7 and transferred to the hot press molding machine 9.

このときワーク把持前のワーク搬送用ロボット７は、図３に示すワーク把持アーム１１のワーク抑え１７を、図３の状態から回転支持軸１９を中心として回転させてフォーク１５から離反させた状態であり、この状態で、３本のフォーク１５上に二つのワークＷを乗せ、その後ワーク把持アーム１１をフォーク１５に近づくよう回転させて、ワーク抑えパッド２５とフォーク１５との間でワークＷを挟むようにして把持する。   At this time, the workpiece transfer robot 7 before gripping the workpiece is in a state in which the workpiece holding member 17 of the workpiece holding arm 11 shown in FIG. 3 is rotated from the state of FIG. In this state, two workpieces W are placed on the three forks 15, and then the workpiece gripping arm 11 is rotated so as to approach the forks 15, so that the workpiece W is sandwiched between the workpiece holding pad 25 and the forks 15. Grip it in a way.

これとほぼ同時に、二つの保持冷却部２９を作動させ、図４に示すように、その冷却ブロック４７，４９により、各ワークＷの穴Ｈをそれぞれ覆うようにしてワークＷを保持し、穴Ｈの周辺部を局所的に冷却し、部分焼き入れを行う。このとき図示しない冷却装置から冷却媒体を入口パイプ５１ａ，５３ａを通して冷却用パイプ５１，５３に供給することで、特に連続生産を行った場合の冷却ブロック４７，４９の高温化を防止し、冷却効率を高める。   At substantially the same time, the two holding cooling units 29 are operated, and the workpieces W are held by the cooling blocks 47 and 49 so as to cover the holes H of the workpieces W as shown in FIG. The peripheral part of the product is locally cooled and partially quenched. At this time, a cooling medium is supplied from a cooling device (not shown) to the cooling pipes 51 and 53 through the inlet pipes 51a and 53a, thereby preventing the cooling blocks 47 and 49 from being heated at the time of continuous production, and cooling efficiency. To increase.

このようにしてワークＷを把持したワーク搬送用ロボット７は、熱間プレス成形機９へ約１０秒間以内で搬送し、熱間ブレス成形機９では、ワークＷに対して熱間プレス成形加工を実施する。成形後はワークＷをワーク取り出しロボット１０により熱間プレス成形機９から取り出す。   The workpiece transfer robot 7 that has gripped the workpiece W in this manner transfers the workpiece W to the hot press molding machine 9 within about 10 seconds, and the hot breath molding machine 9 performs hot press molding processing on the workpiece W. carry out. After molding, the workpiece W is taken out from the hot press molding machine 9 by the workpiece take-out robot 10.

上記した熱間プレス成形加工ラインにおいて、熱間プレス成形でワークＷが所定の硬度を得るためには、プレス開始時のワークＷの温度が所定の温度以上から金型の保持によって急冷を行う必要がある。ワークＷが加熱炉５内から熱間プレス成形機９の金型へ搬送されるまでの間は、ワークＷは大気中での自然放熱による温度低下であるため、焼き入れは行われない。   In the above hot press forming line, in order to obtain a predetermined hardness of the work W by hot press forming, the temperature of the work W at the start of pressing needs to be rapidly cooled by holding the mold from a predetermined temperature or higher. There is. Until the workpiece W is conveyed from the inside of the heating furnace 5 to the mold of the hot press molding machine 9, the workpiece W is lowered in temperature due to natural heat dissipation in the atmosphere, so that quenching is not performed.

本実施形態では、上記した加熱炉５から熱間プレス成形機９へのワークＷの搬送に要する時間を用い、ワークＷ全体の焼き入れ（プレスによる型冷却）の前に、穴Ｈの周辺部のみを保持冷却部２９の冷却ブロック４７，４９で冷却し、部分焼き入れを行う。   In the present embodiment, the time required for transporting the workpiece W from the heating furnace 5 to the hot press molding machine 9 described above is used, and the peripheral portion of the hole H before the entire workpiece W is quenched (die cooling by pressing). Only the cooling blocks 47 and 49 of the holding cooling unit 29 are cooled, and partial quenching is performed.

これにより、その後ワークＷに対して熱間プレス加工を行っても、このプレス成形時に材料流入の影響を受ける部位に穴Ｈが位置する場合であっても、その穴Ｈの周辺は焼き入れされて硬度が高くなっているので、穴Ｈの変形を防止することができ、部品性能を満足した穴径を確保することができる。   As a result, even if hot pressing is performed on the workpiece W afterwards, the periphery of the hole H is quenched even if the hole H is located in a portion affected by the material inflow during the press molding. Since the hardness is high, deformation of the hole H can be prevented, and a hole diameter satisfying the component performance can be secured.

したがって、熱間プレス成形後の硬度が高くなっているワークに対しての穴加工の必要がなく、工具の破損を防止することができる。   Therefore, there is no need for drilling a workpiece having a high hardness after hot press forming, and damage to the tool can be prevented.

また、加熱炉５から熱間プレス成形機９へのワークＷの搬送時間を利用して部分冷却を行うので、部分冷却を行うための新たな時間設定が不要であり、現行の熱間成形プレス加工ラインと同等の作業時間で済み、生産性低下は防止される。   In addition, since the partial cooling is performed using the transfer time of the workpiece W from the heating furnace 5 to the hot press molding machine 9, there is no need to set a new time for performing the partial cooling. The work time is the same as that of the processing line, and productivity decline is prevented.

さらに、穴Ｈの周辺部を部分冷却する保持冷却部２９は、ワーク把持アーム１１に一体化しているので、これら両者を別体とした場合に比較して、構造が簡素化し、装置全体の小型化を達成することができる。   Furthermore, since the holding cooling part 29 for partially cooling the peripheral part of the hole H is integrated with the workpiece gripping arm 11, the structure is simplified and the overall size of the apparatus is reduced as compared with the case where both of them are separated. Can be achieved.

なお、部分焼き入れする穴Ｈの形状や大きさについては、特に制限はなく、それに対応して冷却ブロック４７，４９の形状や大きさを変更すればよい。   In addition, there is no restriction | limiting in particular about the shape and magnitude | size of the hole H to carry out partial hardening, What is necessary is just to change the shape and magnitude | size of the cooling blocks 47 and 49 corresponding to it.

また、部分焼き入れするための保持冷却部２９は、上記した実施形態のように搬送用ロボット７のアーム先端に装着することで、任意の穴の位置に対して容易に位置調整できるが、ロボットを用いずに、例えばレール上をワーク把持アーム１１とともにスライド移動させる構造としてもよい。   In addition, the holding and cooling unit 29 for partial quenching can be easily adjusted with respect to the position of an arbitrary hole by being attached to the tip of the arm of the transfer robot 7 as in the above-described embodiment. It is good also as a structure which slides on the rail with the workpiece | work gripping arm 11, for example, without using.

なお、搬送手段として、上記した実施形態におけるワーク搬送用ロボット７で使用したフォーク１１およびワーク抑え１７を備えるフォーク式に代えて、図６に示すようなワークＷを吊り下げて保持搬送するフック５５を備える吊り下げ式にも、本発明を適用することができる。この場合のフック５５は、レール５７上をスライド移動させ、前記図４に示した保持冷却部２９と同期してレール５７上を移動させる。   In place of the fork type provided with the fork 11 and the work holding member 17 used in the work carrying robot 7 in the above-described embodiment as the transfer means, a hook 55 for hanging and holding the work W as shown in FIG. The present invention can also be applied to a hanging type including In this case, the hook 55 slides on the rail 57 and moves on the rail 57 in synchronization with the holding cooling unit 29 shown in FIG.
