【発明の属する技術分野】
本発明は、主として所定の面形状を有するサンドイッチパネル(例えばハニカムパネル、発泡樹脂サンドイッチパネル)のプレス成形に用いられるパネル製造用治具に関する。
【0002】
【従来の技術】
従来から、所定の曲面形状を有するサンドイッチパネルのプレス成形を行う場合には、パネル製造用治具たる下型101としては、例えば図6に示すように、パネルがサンドイッチ成形されるはずの上側に所定の曲面形状を呈する成形面111aがある板状の成形部111と、成形部111の下側からこれを支持して補強する格子状の補強部112とから構成されるものがある。
ここで、補強部112は、成形部111の下側に溶接により固着され、所定の形状に加工された板材を溶接により格子状に組み固めてなるものである。
【0003】
かかる下型101によれば、成形部111の下側に溶接により格子状に板材を組み固めてなる補強部112を備えるので、プレス成形における成形部111の変形を確実に防止できる強靱な構造を実現させることが可能となる。
【0004】
【発明が解決しようとする課題】
しかしながら、このような下型101では、補強部112により強靱な構造が得られる反面、その製作には、多量の板材の加工や組み立て及び該板材相互間の溶接接合を含む極めて煩雑な作業が必要となり、膨大な労力、時間及び費用を要してしまう。
【0005】
また、成形部111の上側にある成形面111aにおいては、サンドイッチパネルの品質に対応する正確な曲面形状が必要となるところ、溶接接合により製作される補強部112に溶接残留応力に伴うひずみにより不可避的なソリ、組み合わせによる段差が発生してしまう。また、成形面111aと補強部112を溶接すれば、成形面111aに直接ソリが発生する。そのようなソリ、段差があると、必要な平坦度を満たす正確な成形面111aの曲面形状を製作することは実際上かなり困難である。また、繰り返し使用に伴う熱影響により成形部111に反りが発生する不具合もある。
【0006】
さらに、近年、パネル形状の多様化、複雑化に伴い、異なる曲面形状を有するサンドイッチパネルが必要となった場合には、成形面111aの形状ひいては補強部112の形状を変更する必要がある。
【0007】
ところが、従来における下型101では、複数の板材を溶接により相互に格子状に組み固めてなるような強靱な構造体を補強部112としている。それゆえ、そのような補強部112の形状変更は殆ど不可能であり、成形面111aの形状を変更するには、補強部112全体をそっくり交換することが必要となる。
つまり、かかる下型101では、多様化するパネルの形状に機動的かつ柔軟に対応できず、ひいては資材の有効利用が図れないという問題がある。
【0008】
一方、所定の曲面形状を有するサンドイッチパネルのプレス成形を行う場合におけるパネル製造用治具たる上型102としては、例えば前記した下型101と略同様の構成を有するものがある。
すなわち、従来からの上型102としては、例えばパネルがサンドイッチ成形されるはずの下側に所定の曲面形状を呈する成形面121aがある板状の成形部121と、成形部121の上側からこれを保持して補強する格子状の補強部122とからなるものがある。
【0009】
かかる上型102によっても、成形部121の上側に溶接により格子状に板材を組み固めてなる補強部122を備えるので、プレス成形に伴う成形部121の変形を確実に防止できる強靱な構造を実現させることが可能となるが、反面、前記した下型101と略同様の問題を有している。
特に、このような下型101と略同様の構造を有する上型102では、仮に下型101において正確な成形面111aの曲面形状が得られた場合でも、さらに下型101の成形面111aの曲面形状に正確に合致した曲面形状を上型102の成形面121aにおいて実現させることは、前記した溶接残留応力の問題に照らしてみて実際上殆ど不可能であるといえる。
【0010】
他方、従来からの下型101や上型102には、溶接により格子状に強固に組み固めてなるという構造上、解体して置くことができず、多大な保管スペースが必要となるという問題がある。
【0011】
そこで、本発明の課題は、補強部が極めて短時間で容易に得られ、成形面の形状の正確さも容易に確保され、多様化するパネルの形状に機動的かつ柔軟に対応でき、保管スペースも比較的とらない、パネル製造用治具を提供することにある。
【0012】
【課題を解決するための手段】
すなわち、本発明に係るパネル製造用治具は、パネルがサンドイッチ成形されるはずの下型と上型とからなるパネル製造用治具において、前記下型は、上側に所定の面形状を呈する成形面がある板状の成形部と、前記成形部の下側から該成形部を保持し補強する補強部とを備え、前記下型の補強部は、複数の面受部材と、前記面受部材を所定の受面間隔で立てて並べて固着する架台と、前記架台により下端部が支持され、かつ、前記面受部材により側面が面受されることにより、上端部が前記成形面の前記面形状に対応する形状を呈するよう位置決めされる複数の補剛板と、前記面受部材に対して前記補剛板を着脱自在にかつ機械的に接合する接合手段とを含み、前記上型は、下側にパネルの変形に追従する変形が可能な板状部材を有する成形部と、前記成形部の上側から該成形部の追従変形を妨げないように、クレーンにより吊り下げられる吊下部を備え、かつ、前記成形部を保持して補強するようにした補強部とを含むことを特徴としている。
【0014】
このパネル製造用治具によれば、補強部の構築の大半を占める補剛板の面受部材への接合作業を位置決めしながら機械的にできることとしたので、補強部が極めて短時間で容易に得られ、膨大な労力、時間及び費用を要する煩雑な作業を回避することが可能となる。
また、補強部の構築において残留応力に伴うソリ、段差ができるような溶接接合を回避することとしたので、補剛板の天端に段差が発生することがなく、成形面の形状の正確さも容易に確保される。
さらに、補剛板の面受部材への接合を着脱自在とし、形状の異なる補剛板への取り替え作業が自由にできるので、多様化するパネルの形状に機動的かつ柔軟に対応可能となる。
さらにまた、これらのパネル製造用治具を容易に解体して置くことができるので、多大な保管スペースが必要となるという問題を解消することが可能となる。
【0015】
また、本発明に係るパネル製造用治具は、パネルがサンドイッチ成形されるはずの下側に所定の面形状を呈する成形面がある板状の成形部と、前記成形部の上側から該成形部を保持して補強する補強部とを含むパネル製造用治具において、前記成形部は、パネルの変形に追従する変形が可能であり、前記補強部は、前記成形部の追従変形を妨げないように、該成形部の上側面に所定の間隔で並べて固着される複数の棒状部材(おもし)からなるとともに、クレーンにより略水平に吊り下げられる棒状の吊下部材及びこの吊下部材により吊り下げられ、かつ、前記棒状部材に固着される複数のフック部材からなる吊下部を含むことを特徴としている。
【0016】
このパネル製造用治具によれば、補強部の構築が、複数の棒状部材の板状の成形部の上側面への固着及び複数のフック部材の棒状部材への固着のみによりできるので、補強部が極めて短時間で容易に得られ、膨大な労力、時間及び費用を要する煩雑な作業を回避することが可能となる。
また、補強部の構築において残留応力に伴う段差ができるような溶接接合を回避しながら、パネルの変形に追従する変形が可能な成形部としたので、下型の成形面の曲面形状に正確に合致した成形面の形状が容易かつ確実に得られ、多様化するパネルの形状にも機動的かつ柔軟に対応できる。
さらにまた、従来は、上型の上に加圧のためのおもしをのせる必要があったが、このようなパネル製造用治具により、おもしを兼ねることが可能となる。
【0017】
【発明の実施の形態】
以下、添付図面に基づいて本発明の実施の形態を詳細に説明する。
【0018】
◎実施の形態1
図1は本発明の実施の形態1に係るパネル製造用治具(下型及び上型)の全体構成を示す斜視図、図2は該パネル製造用治具(下型)の部分構成を示す側面図、図3は該パネル製造用治具(下型)における接合手段を示す斜視図、図4は該パネル製造用治具における補剛板のバリエーションを示す側面図である。
【0019】
この実施の形態1において、パネル製造用治具(以下「下型」という)としては、図1に示すように、成形部1と、補強部2とから構成されている。以下、これらの各構成要素について詳細に説明する。
【0020】
[成形部1]
成形部1は、同図に示すように、パネルPがサンドイッチ成形されるはずの上側に所定の面形状を呈する成形面を有するものとして構成されている。
ここで、成形面において、所定の面形状が得られるようにするには、曲加工を行うこととなるが、曲加工を行わなくても、板厚を適当に設定することにより、補強部2の曲面になじませることができる。
具体的には、この成形部1は、同図に示すような板状部材11などからなるものであり、例えば鋼板やアルミニウム板などを用いることができる。
【0021】
[補強部2]
補強部2は、成形部1の下側から成形部1を保持して補強するものであり、同図に示すように、複数の面受部材たるL型部材21と、架台22と、複数の補剛板たるスケルトン板23と、接合手段24とから構成されている。
ここで、これらの各構成要素についてさらに詳細に説明する。
【0022】
(1)L型部材21
L型部材21は、同図に示すように、架台22に対して所定の受面間隔で立てて並べられて固着されるものであり、スケルトン板23を面受けすることにより位置決めする役割を果たすものである。
(2)架台22
架台22は、同図に示すように、面受部材たるL型部材21を所定の受面間隔で立てて並べて固着する役割を果たすものである。
【0023】
この架台22は、具体的には、同図に示すようなスケルトン板23の板面方向に直交する方向で配設される棒状部22aを含むものとして構成されている。この棒状部22aとしては、例えば2本以上の鋼製コラムやH形鋼などを含むものとして構成することができる。
また、この架台22には、図1及び図2に示すようなアジャスター機構22bが設けられており、これにより、基盤としての鉄筋コンクリート基礎Cに対する架台22の位置決めが短時間で容易にできるようになっている。
なお、アジャスター機構22bに代えて、例えばレベリングブロックを用いても同様の効果が得られる。
【0024】
(3)複数のスケルトン板23
複数のスケルトン板23は、図1に示すように、架台22により下端部が支持され、かつ、L型部材21により側面が面受されることにより、上端部が成形面の面形状に対応する形状を呈するよう位置決めされるものである。
【0025】
このスケルトン板23としては、材料の別を問わず、例えば金属板の他、合板などであっても差し支えない。
また、このスケルトン板23は、具体的には、上端部が同図に示すような成形面の面形状に対応する形状に加工されている。
なお、このような形状への加工は、例えばレーザーやNCルーターなどの他、プレスなどによることができる。これらの加工手段によれば、スケルトン板23を例えば0.1mm以下の精度で加工することが可能となる。
また、このスケルトン板23は、図3に示すように、L型部材21で面受されているとともに接合手段24で接合されていない状態で位置決めされるように、棒状部22aに嵌装される凹部23aを含むものとして構成されている。また、接合手段24を用いて行うスケルトン板23のL型部材21への着脱操作がワンタッチでできるように、矩形の凹部23aに連通する長孔部23bも設けられている。
【0026】
(4)接合手段24
接合手段24は、L型部材21に対してスケルトン板23を着脱自在にかつ機械的に接合する役割を果たすものである。
【0027】
具体的には、この接合手段24としては、図3に示すようなボルト部材24a、ナット部材24b及び座金部材24cが用いられる。これによれば、スケルトン板23のL型部材21への着脱操作がワンタッチでできることとなる。
【0028】
次に、この実施の形態1に係る下型の製作方法について図1を用いて説明する。なお、本下型の製作方法は、補強部製作段階と、成形部取付段階とからなっている。以下、各段階に分けて簡単に説明する。
【0029】
[補強部製作段階]
補強部製作段階は、基盤としての鉄筋コンクリート基礎Cにより支持される架台22及び架台22により所定の板面間隔で立てて並べられて支持される複数のスケルトン板23を含む補強部2を構築する段階である。
【0030】
この補強部製作段階は、具体的には、第一位置決め工程と、第二位置決め工程と、第三位置決め工程とからなっている。以下、各工程についてさらに説明する。
【0031】
(1)第一位置決め工程
第一位置決め工程は、アジャスター機構22bにより、鉄筋コンクリート基礎Cに対する架台22の位置決めをする工程である(図2参照)。
【0032】
(2)第二位置決め工程
第二位置決め工程は、スケルトン板23の上端部が成形面の面形状に対応する形状を呈するように、架台22に対するスケルトン板23の下端部の当接による位置決めをするとともにL型部材21に対するスケルトン板23の側面の当接による位置決めする工程である(図2参照)。
【0033】
(3)第三位置決め工程
第三位置決め工程は、接合手段24を用いて、L型部材21に対するスケルトン板23が着脱自在であって機械的な接合による位置決めをする工程である(図3参照)。
【0034】
[成形部取付段階]
成形部取付段階は、補強部構築段階で構築された補強部2にパネルPがサンドイッチ成形されるはずの成形部1を取り付ける段階である。
【0035】
以上説明したように、この実施の形態1に係る下型及びその製作方法によれば、補強部2の構築の大半を占めるスケルトン板23のL型部材21への接合作業を位置決めしながら機械的に行うこととしたので、補強部2が極めて短時間で容易に得られ、膨大な労力、時間及び費用を要する煩雑な作業を回避することが可能となる。
【0036】
また、補強部2の構築において残留応力に伴うソリ及び段差ができるような溶接接合を回避することとしたので、スケルトン板23の天端に段差が発生することがなく、成形面の形状の正確さも容易に確保される。
【0037】
さらに、スケルトン板23のL型部材21への接合を着脱自在とし、形状の異なるスケルトン板23への取り替え作業が自由にできるので、多様化するパネルPの形状に機動的かつ柔軟に対応可能となる。例えば図4に示すように、フラットタイプ(図4(a)参照)や曲面タイプ(図4(b)参照)の他、折り曲げタイプ(図4(c)参照)にも、容易に対応可能となる。
【0038】
さらにまた、このような下型によれば、極めて容易に解体して置くことができるので、多大な保管スペースをとらないという利益が得られる。
【0039】
◎実施の形態2
図1は本発明の実施の形態2に係るパネル製造用治具(上型)の全体構成を示す斜視図、図5は該パネル製造用治具の部分構成を示す図(図5(a)は側面図、図5(b)は溶接箇所を示す平面図、図5(c)は作用を説明する側面図、)である。
【0040】
この実施の形態1において、パネル製造用治具(以下「上型」という)は、図1に示すように、成形部3と、補強部4と、吊下部5とから構成されている。以下、これらの各構成要素について詳細に説明する。
【0041】
[成形部3]
成形部3は、パネルPがサンドイッチ成形されるはずの下側に所定の面形状を呈する成形面がある板状のものである。
【0042】
この成形部3は、具体的には、同図に示すような板状部材31からなるものであり、例えば極めて薄い鋼板(t=1.2mm)を用いることができる。
すなわち、このような成形部3は、同図に示すように、パネルPの形状に追従する変形が可能なものとして構成されている。
[補強部4]
補強部4は、同図に示すように、成形部3の上側から成形部3を保持して補強するとともに、プレス荷重のおもしとしての役割を果たすものである。
【0043】
この補強部4は、同図に示すように、成形部3の追従変形を妨げないように、成形部3の上側面に所定の間隔で並べて固着される複数の棒状部材41からなっている。ここで、かかる棒状部材41としては、同図に示すような角棒を用いているが、丸棒などを適宜選定しても差し支えない。
すなわち、このような複数の棒状部材41によれば、所定の間隔をあけて並べられているので、成形部3が図5(c)に示すように追従変形した場合にも、隣り合うもの同士が互いに競り合うことがなく、また、曲げ方向に直交する方向に並べられているので、成形部3の追従変形に柔軟に対応可能となり、成形部3の追従変形を妨げないこととなっている。
一方、複数の棒状部材41の成形部3の上側面への固着は、図5(b)に示すように、点溶接41aにより行われている。このような溶接方法も、成形部3の追従変形を妨げない作用を奏するものである。
【0044】
[吊下部5]
吊下部5は、図1及び図5(a)に示すように、クレーン(図示外)により略水平に吊り下げられる棒状の吊下部材51及びこの吊下部材51により串刺し状に吊り下げられ、かつ、棒状部材41に固着される複数のフック部材52からなっている。
ここで、複数のフック部材52において棒状の吊下部材51によって直接吊り下げられる部分としては、串刺し状に吊り下げられる閉じた環形状を呈するものを用いているが、これに限られるものではなく、単純なフック形状を呈するものを用いても勿論差し支えない。
【0045】
このような上型によれば、補強部4の構築が、複数の棒状部材41の板状の成形部3の上側面への固着及び複数のフック部材52の棒状部材41への固着のみによりできるので、補強部4が極めて短時間で容易に得られ、膨大な労力、時間及び費用を要する煩雑な作業を回避することが可能となる。
【0046】
また、補強部4の構築において残留応力に伴う段差ができるような溶接接合を回避しながら、パネルPの変形に追従する変形が可能な成形部3としたので、下型の成形面の曲面形状に正確に合致した成形面の形状が容易かつ確実に得られ、多様化するパネルPの形状にも機動的かつ柔軟に対応できる。
【0047】
さらにまた、棒状部材41の形状を変えることによりプレスに必要な荷重を得ることができるので、従来のような上型の上におもしを置くという工程を一工程とすることができる。
本実施の形態においては、成形部3は一体化しているが、これに限られるものではなく、例えば更に下に一枚敷くことも可能である。
【0048】
【発明の効果】
本発明に係るパネル製造用治具によれば、補強部が極めて短時間で容易に得られ、成形面の形状の正確さも容易に確保され、多様化するパネルの形状に機動的かつ柔軟に対応できる。

BACKGROUND OF THE INVENTION
The present invention relates primarily sandwich panel (e.g. honeycomb panels, foamed resin sandwich panel) having a predetermined surface shape panel manufacturing jig for use in press molding.
[0002]
[Prior art]
Conventionally, when press-molding a sandwich panel having a predetermined curved surface shape, as the lower mold 101 as a panel manufacturing jig, for example, as shown in FIG. Some include a plate-shaped molding portion 111 having a molding surface 111a exhibiting a predetermined curved surface shape, and a lattice-shaped reinforcement portion 112 that supports and reinforces the molding surface 111 from below.
Here, the reinforcing part 112 is fixed to the lower side of the forming part 111 by welding, and a plate material processed into a predetermined shape is assembled into a lattice shape by welding.
[0003]
According to the lower mold 101, the reinforcing portion 112 is formed by assembling the plate material in a lattice shape by welding on the lower side of the forming portion 111, and thus has a tough structure that can reliably prevent deformation of the forming portion 111 in press molding. It can be realized.
[0004]
[Problems to be solved by the invention]
However, in such a lower mold 101, a tough structure can be obtained by the reinforcing portion 112, but its production requires extremely complicated work including processing and assembly of a large amount of plate materials and welding joining between the plate materials. Therefore, enormous labor, time and cost are required.
[0005]
In addition, in the molding surface 111a on the upper side of the molding part 111, an accurate curved surface shape corresponding to the quality of the sandwich panel is required. However, the reinforcing part 112 manufactured by welding joining is unavoidable due to distortion caused by welding residual stress. Level difference due to warpage and combination. Further, if the molding surface 111a and the reinforcing portion 112 are welded, warping is directly generated on the molding surface 111a. If there are such warps and steps, it is practically difficult to produce an accurate curved surface shape of the molding surface 111a that satisfies the required flatness. In addition, there is also a problem that warpage occurs in the molded part 111 due to the thermal effect associated with repeated use.
[0006]
Further, in recent years, when a sandwich panel having a different curved surface shape is required as the panel shape is diversified and complicated, it is necessary to change the shape of the molding surface 111a and the shape of the reinforcing portion 112.
[0007]
However, in the conventional lower mold 101, the reinforcing portion 112 is a tough structure in which a plurality of plate materials are assembled together in a lattice form by welding. Therefore, it is almost impossible to change the shape of the reinforcing portion 112. To change the shape of the molding surface 111a, it is necessary to replace the entire reinforcing portion 112.
That is, the lower mold 101 has a problem that it cannot flexibly and flexibly cope with diversified panel shapes, and as a result, materials cannot be effectively used.
[0008]
On the other hand, as the upper mold 102 as a panel manufacturing jig in the case of performing press molding of a sandwich panel having a predetermined curved surface shape, for example, there is one having substantially the same configuration as the lower mold 101 described above.
That is, as the conventional upper mold 102, for example, a plate-shaped molding part 121 having a molding surface 121 a having a predetermined curved surface shape on the lower side where the panel is to be sandwich-molded, and the upper side of the molding part 121. Some include reinforcing portions 122 in the form of lattices that are held and reinforced.
[0009]
The upper mold 102 also includes a reinforcing portion 122 that is formed by assembling plate materials into a lattice shape by welding on the upper side of the molding portion 121, thereby realizing a tough structure that can reliably prevent deformation of the molding portion 121 due to press molding. However, it has substantially the same problem as the lower mold 101 described above.
In particular, in the upper mold 102 having a structure substantially similar to that of the lower mold 101, even if an accurate curved surface shape of the molding surface 111a is obtained in the lower mold 101, the curved surface of the molding surface 111a of the lower mold 101 is further obtained. It can be said that it is practically impossible to realize a curved surface shape that exactly matches the shape on the molding surface 121a of the upper mold 102 in view of the above-described problem of welding residual stress.
[0010]
On the other hand, the conventional lower mold 101 and upper mold 102 have a problem in that they cannot be disassembled due to the structure that they are firmly assembled in a lattice shape by welding, and a large storage space is required. is there.
[0011]
Therefore, the problem of the present invention is that the reinforcing portion can be easily obtained in a very short time, the accuracy of the shape of the molding surface can be easily secured, the shape of the diversified panel can be flexibly and flexibly handled, and the storage space is also increased. The object is to provide a jig for manufacturing a panel which is relatively small.
