〔技術分野〕
本考案は溝加工による折曲加工された板材に関
する。[Detailed Description of the Invention] [Technical Field] The present invention relates to a plate material bent by groove processing.
木材、合板、パーテイクルボード、インシユレ
ーシヨンボードを基板として折曲加工することは
従来から試みられている。
Previous attempts have been made to bend wood, plywood, particle board, and insulation board as substrates.
これらの基板の材質は、繊維の方向性があるこ
とと、比重が大きすぎたり、小さすぎ剛性が強す
ぎたり弱すぎたりして折れ易く、折曲加工するこ
とは不可能であつた。 The materials of these substrates are easily bent due to the directional nature of the fibers, too high or too low specific gravity, and too strong or too weak rigidity, making it impossible to bend them.
すなわち、繊維方向と直角方向に折曲げると折
れ易く、さらにささくれを生ずる。また繊維方向
と平行方向に折曲げると、繊維方向に割れ易く、
また、ささくれも生じ易い。 That is, if it is bent in a direction perpendicular to the fiber direction, it is likely to break, and furthermore, hangnails will occur. Also, if you bend it parallel to the fiber direction, it will easily break in the fiber direction.
Also, hangnails are likely to occur.
したがつて生産性も悪く歩留りが著しく低いと
いう問題点があつた。 Therefore, there were problems in that the productivity was poor and the yield was extremely low.
またこのような折れ易さを緩和するため、基板
の表面側に塩化ビニールなどのシート状物を貼着
し、裏面側から基板の全厚にわたつて切り込みを
入れて基板自体を切断し、この切り込み部を折曲
げて折曲加工することも試みられた。 In addition, in order to reduce this tendency to bend, a sheet-like material such as vinyl chloride is pasted on the front side of the board, and the board itself is cut by making a cut from the back side over the entire thickness of the board. Attempts have also been made to bend the notch.
しかし、上記のような従来の折り曲げ加工する
板材では予じめ基板にシート状物を貼着しなくて
はならず、製造工程が煩雑で、生産性も低いだけ
でなく、繊維に方向性があるため、切込みの切削
が容易でなく、歩留りが著しく低下するという問
題点があつた。
However, in the conventional bending process as described above, a sheet material must be attached to the substrate in advance, which not only makes the manufacturing process complicated and has low productivity, but also causes the fibers to have no directionality. Therefore, there was a problem in that cutting the depth of cut was not easy and the yield was significantly reduced.
本考案はこのような従来技術の問題点を解決す
ることを目的とする。 The present invention aims to solve these problems of the prior art.
本考案は上記のような従来技術の問題点を解決
するため基板として、比重0.4〜0.8の繊維の方向
性の無いいわゆる中質繊維板を用い、表面に合成
樹脂を含浸し、その裏面に基板を残存基部として
0.5〜５mmに残すように溝を形成し、該溝を中心
に裏面側に折曲げて、板材を形成したものであ
る。
In order to solve the problems of the conventional technology as described above, the present invention uses a so-called medium density fiberboard with a specific gravity of 0.4 to 0.8 and no directionality of fibers as a substrate.The surface is impregnated with synthetic resin, and the back side is coated with a substrate. as the remaining base
A groove is formed so as to leave a width of 0.5 to 5 mm, and the plate material is formed by bending the groove toward the back side.
本考案の折曲加工された板材は、
基板１として中質繊維板またはこれに類似し
た性状の繊維の方向性の無い繊維板を用いたこ
と、
合成樹脂３を基板１の表面に含浸したこと。
The bent plate material of the present invention uses a medium-density fiberboard or a non-directional fiberboard with similar properties as the substrate 1, and impregnates the surface of the substrate 1 with a synthetic resin 3. .
溝７，２の深さは残存基部４が0.5〜５mmと
したこと、
を要件として構成されている。また中質繊維板は
繊維の方向性が無いため、折曲加工に対して亀裂
の生ずることなく、折曲部の強度の低下しない折
曲板材が得られる。 The depth of the grooves 7 and 2 is configured with the requirement that the remaining base portion 4 be 0.5 to 5 mm. Furthermore, since the medium-density fiberboard has no fiber directionality, it is possible to obtain a bent plate material that does not cause cracks during bending processing and does not reduce the strength of the bent portion.
以下本考案の実施例について説明する。 Examples of the present invention will be described below.
原材Ａは比重0.4〜0.8の繊維の方向性のない木
質繊維板を基板１とする。木質繊維板は針葉樹材
木質フアイバーを用いた針葉樹繊維板、広葉樹材
木質フアイバーを用いた広葉樹繊維板、針葉樹材
木質フアイバーと広葉樹材木質フアイバーを混合
して用いた繊維板などいずれでもよい。 The substrate 1 of the raw material A is a wood fiberboard with non-directional fibers having a specific gravity of 0.4 to 0.8. The wood fiberboard may be a softwood fiberboard using softwood wood fibers, a hardwood fiberboard using hardwood wood fibers, a fiberboard using a mixture of softwood wood fibers and hardwood wood fibers, etc.
つぎに基板１の表面に合成樹脂をロールコータ
ー、フローコーターなどの塗装装置あるいはＴダ
イスなどの塗布装置を用いて塗布含浸し、乾燥し
て合成樹脂含浸層３を形成する。 Next, a synthetic resin is coated and impregnated onto the surface of the substrate 1 using a coating device such as a roll coater or a flow coater, or a coating device such as a T die, and is dried to form a synthetic resin impregnated layer 3.
合成樹脂としてはアクリル、アミノ、アルキツ
ド、ウレタン、ポリエチレン、ポリエステルなど
の樹脂を用いる。 As the synthetic resin, resins such as acrylic, amino, alkyd, urethane, polyethylene, and polyester are used.
第５，６図のように合成樹脂は折曲加工すべき
部分の表面にのみ塗布含浸し、合成樹脂含浸層を
形成してもよい。 As shown in FIGS. 5 and 6, the synthetic resin may be applied and impregnated only on the surface of the portion to be bent to form a synthetic resin-impregnated layer.
つぎに合成樹脂を表面に含浸した基板の裏面側
に多軸ランニングソー、Ｖ溝加工機などの加工機
を用いて、Ｖ溝７、櫛目溝２などの溝を形成す
る。第１〜５図では櫛目溝２を形成し、第６〜第
９図ではＶ字溝を形成している。これらの溝２，
７は基板１に0.5〜５mmの残存基部４を残す程度
に切り込む。 Next, grooves such as the V groove 7 and the comb groove 2 are formed on the back side of the substrate whose surface is impregnated with synthetic resin using a processing machine such as a multi-axis running saw or a V groove processing machine. In FIGS. 1 to 5, comb grooves 2 are formed, and in FIGS. 6 to 9, V-shaped grooves are formed. These grooves 2,
7 cuts into the substrate 1 to such an extent that a residual base portion 4 of 0.5 to 5 mm is left.
基板１の比重が0.4以下であると、柔軟すぎて
しまい、特に櫛目溝加工の時櫛歯６が形成でき
ず、逆に比重0.8以上であると、剛性が強く櫛目
溝加工の時、櫛歯６が欠け易く好ましくなく、ま
た折曲げ時折れ易い。 If the specific gravity of the substrate 1 is less than 0.4, it will be too flexible, making it difficult to form comb teeth 6, especially when machining comb grooves.On the other hand, if the specific gravity is 0.8 or more, the rigidity will be too strong and the comb teeth will not form when machining comb grooves. 6 is undesirable because it tends to chip, and it also tends to tear when bent.
基板１を５mm以上残すように形成した時、引張
り強度が強く、折曲げ時折れ易く、角度を小さ
く、また曲率半径を小さく折曲げることができな
い。 When the substrate 1 is formed so that 5 mm or more is left, the tensile strength is strong and it easily breaks when bent, and it is impossible to bend the substrate 1 at a small angle or with a small radius of curvature.
基板を0.5mm以下残すように形成した時、残さ
れた基板の引張り強度が低くなるため、折曲げ時
に櫛目溝部で残された基板が切断し易い。 When the substrate is formed so that 0.5 mm or less of the substrate remains, the tensile strength of the remaining substrate becomes low, so that the remaining substrate is easily cut at the comb groove portion during bending.
つぎに、溝２，７内に接着剤５を塗布あるいは
充填し、該溝部を中心に裏面側に折曲げ、所定の
保持具で保持固定し、接着剤５を乾燥固化し折曲
加工する。 Next, the adhesive 5 is applied or filled into the grooves 2 and 7, bent toward the back side around the grooves, held and fixed with a predetermined holder, and the adhesive 5 is dried and solidified to perform the bending process.
以上の如くして折曲加工された板材を得た。ま
た折曲加工された板材の折曲げ部裏面側に補強
棧、補強合成樹脂層などによる補強材８を取付け
てもよい。 A bent plate material was obtained as described above. Further, a reinforcing member 8 such as a reinforcing rod or a reinforcing synthetic resin layer may be attached to the back side of the bent portion of the bent plate material.
また第１〜４図の櫛歯６は第５図のように台形
にしてもよい。 Moreover, the comb teeth 6 shown in FIGS. 1 to 4 may be trapezoidal as shown in FIG. 5.
〔本考案の効果〕
基板１として比重0.4〜0.8の木質繊維板を用
い、繊維板自体が適度の剛性、柔軟性を有する
とともに均質材であり、繊維方向性がないの
で、溝加工が容易に行なえる。[Effects of the present invention] Wood fiberboard with a specific gravity of 0.4 to 0.8 is used as the substrate 1, and the fiberboard itself has appropriate rigidity and flexibility, is a homogeneous material, and has no fiber directionality, making groove processing easy. I can do it.
表面に樹脂が含浸されており、基板のもつ柔
軟性、樹脂の持つ弾力性が相俟つて容易に折り
曲げ加工が行なえる。 The surface is impregnated with resin, and the combination of the flexibility of the substrate and the elasticity of the resin allows for easy bending.
