Description
本発明は、ガラス繊維や炭素繊維などの繊維と組み合わせることで強度を高めた繊維強化樹脂材の成形品製造装置およびこの成形品製造装置を用いた繊維強化樹脂材の成形品の製造方法に関する。 The present invention relates to a fiber-reinforced resin material molded product manufacturing apparatus whose strength is increased by combining with fibers such as glass fiber and carbon fiber, and a method for manufacturing a fiber-reinforced resin material molded product using this molded product manufacturing apparatus.
上記のガラス繊維、炭素繊維の他、使用される繊維としてはセルロース、ボロンやアラミド等の合成樹脂の繊維が知られている。これらの繊維を連続繊維あるいは不連続繊維(短繊維)として熱硬化性樹脂あるいは熱可塑性樹脂を含浸もしくは混合した素材は、プリプレグやシートモールディング・コンパウンド(SMC)、あるいはテープ状、シート状、マット状などの形態とした繊維強化樹脂材(加工材)で提供される。 In addition to the above glass fibers and carbon fibers, synthetic resin fibers such as cellulose, boron and aramid are known as the fibers used. The material obtained by impregnating or mixing these fibers with a thermosetting resin or a thermoplastic resin as continuous fibers or discontinuous fibers (short fibers) is a prepreg, a sheet molding compound (SMC), or a tape-like, sheet-like, or mat-like material. It is provided as a fiber reinforced resin material (processed material) in the form of.
上記の素材をプレスで所望の形状に成形して繊維強化樹脂材(FRP)成形品として製造され、建材や船舶あるいは航空機の構成材などの広い分野に供給されている。
プレス成形は、一対の金型(一般的には、一方:雌形状の上金型(キャビティ)、他方:雄形状の下金型(コア))を油圧シリンダあるいは電動モータで駆動されるスライドで上下させ、前記一対の金型の間(下金型の上)に挿置した加工素材(例えばプリプレグ)をプレスで加熱圧縮して所要の形状に成形し、冷却した後に上下の金型を開いて製品として取り出す。
The above materials are molded into a desired shape by a press to be manufactured as a fiber reinforced plastic (FRP) molded product, and are supplied to a wide range of fields such as building materials and constituent materials of ships or aircraft.
Press forming is a slide in which a pair of dies (generally, one: female-shaped upper die (cavity) and the other: male-shaped lower die (core)) are driven by a hydraulic cylinder or an electric motor. The processed material (for example, prepreg) that is moved up and down and inserted between the pair of dies (above the lower die) is heated and compressed by a press to form a required shape, cooled, and then the upper and lower dies are opened. And take it out as a product.
この種の先行技術を開示したものとしては、特許文献1を挙げることができる。特許文献1は入駒を使用したプレスでの加圧と加温の不均一による樹脂含浸のばらつきを入駒と加熱手段の間に弾性体を設けることで解消したプレス成形金型とそれを用いた成形方法を開示する。
プレスでプリプレグなどの成形素材を成形する際の金型による加熱圧縮の後に、製品を取り出すまでの形状安定に要する金型の冷却時間は生産時間(プロセスタイム、サイクルタイム)に大きく依存する。
特許文献1では、成型素材に所要の形状を付与するための一対の金型の一方の転写成型部と他方の転写成型部に加熱手段(ヒーター)が埋設されており、成型素材に直接的に熱エネルギーを供給するように隣接配置されている。一方、冷却手段としての冷水の流路は可動金型と固定金型の上記転写成型部とは反対側、すなわち、加熱手段の外側に設けられている。
The cooling time of the mold, which is required to stabilize the shape until the product is taken out after heating and compression by the mold when molding a molding material such as prepreg with a press, largely depends on the production time (process time, cycle time).
In
この構成では、加熱圧縮で所要の成型処理をした後に、冷却手段が金型(転写成型部)と成型品の温度を下げて金型を開いて成型品の取り出しができるまでにかなりの時間が必要となる。すなわち、ヒーターへの電力を停止して冷却手段に冷水を流しても金型(入駒)には相当量の余熱が残留しているので、冷却手段はこの余熱の吸い出しもしなければならず、金型の温度が成型品を取出し可能な値にさがるまでに長時間を必要とする。このことは、製造プロセスのサイクルタイム短縮の障害となり、所謂ハイサイクルを達成するために解決すべき課題となっている。 In this configuration, it takes a considerable amount of time for the cooling means to lower the temperature of the mold (transfer molding part) and the molded product, open the mold, and take out the molded product after performing the required molding process by heat compression. You will need it. That is, even if the electric power to the heater is stopped and cold water is passed through the cooling means, a considerable amount of residual heat remains in the mold (entry piece), so that the cooling means must also suck out this residual heat. It takes a long time for the temperature of the mold to reach a value at which the molded product can be taken out. This becomes an obstacle to shortening the cycle time of the manufacturing process, and is a problem to be solved in order to achieve a so-called high cycle.
本発明は、上記した先行技術の課題を解決し、プレスによる繊維強化樹脂材の成形品製造におけるサイクルタイムを短縮してハイサイクルな量産化を促進可能とすることにある。 The present invention is to solve the above-mentioned problems of the prior art, shorten the cycle time in the production of a molded product of a fiber reinforced resin material by a press, and promote high-cycle mass production.

上下の金型(1、2)と上下の加熱プレート(5、6)が“熱的接合で配置”されるとは、上下の金型(1、2)と上下の加熱プレート(5、6)とが良好な熱伝導するような一体的結合がなされていることを意味する。
ここで、上下の金型(1、2)は、それぞれ冷却手段(21、22)を備えており、冷却手段(21、22)により、上下の金型(1、2)は、冷却がスムーズに行うことができる。
また、上下金型(1、2)と加熱プレート(5、6)とが“熱的接触配置”されるとは、上記の“熱的接合で配置”の状態を作るが、その接触が解除可能とされるように構成されていることを意味する。
The upper and lower molds (1, 2) and the upper and lower heating plates (5, 6) are "arranged by thermal bonding" when the upper and lower molds (1, 2) and the upper and lower heating plates (5, 6) are arranged. ) Means that an integral bond is formed so as to conduct good heat conduction.

It is sectional drawing schematically explaining an example of a heating plate.
In FIG. 5, a serpentine tube (cooling medium flow path) is formed as upper and lower cooling means 21 and 22 made of a metal bulk material, and in this embodiment, cold water flows through this as a cooling medium. The cooling medium is not particularly limited as long as it can be cooled, and may be, for example, oil.
The cooling medium is distributed from the cooling medium source / opening / closing means 28 to the recovery means 30 through the cooling medium flow path to lower the temperature of the upper and lower molds (1, 2).
Although the cross section of the upper mold is shown in FIG. 5, the description of the upper unit pins 7a to 7d and the like is omitted for the sake of clarity.

In FIG. 6, a plurality of cartridge heaters (26, 27) are installed on the upper and lower heating plates (5, 6) to heat the heating plates (5, 6).
During the period when the heating plates (5, 6) are supplying heat energy to the upper and lower molds (1, 2), the supply of the cooling medium is stopped.

Further, heating oil or heating steam can be passed through a serpentine tube similar to the above-mentioned cooling medium flow path for heating.

以下、図7Aと図7B及び図8を参照して本発明に係る製造方法の1実施例を説明する。
FIG. 7A is a schematic diagram illustrating a molded product manufacturing process of the fiber reinforced resin material according to the present invention, and FIG. 7B is a schematic diagram illustrating a molded product manufacturing process following FIG. 7A. FIG. 8 is a flow chart illustrating an example of a procedure for manufacturing a molded product of the fiber reinforced resin material according to the present invention.
Hereinafter, one embodiment of the manufacturing method according to the present invention will be described with reference to FIGS. 7A, 7B, and 8.
初期状態では、図示しないスライドは待機位置に停止しており、上側ユニット100と下側ユニット200は、図1に示したように上金型1のキャビティ1aと下金型2のコア2aとが離間した状態となっている。
上金型1の背面には、上加熱プレート5が上側ユニットバネ11a~11d(11c~11dは不図示)の伸張で離間された状態で設置されている。
In the initial state, the slide (not shown) is stopped at the standby position, and the
The
なお、下金型2についても同様に、下金型1の背面に下加熱プレート6が伸縮部材である下側ユニットバネ12a~12d(12c~12dは不図示)の伸張で離間した状態で設置されている。この状態で上下ユニット(100、200)がスタンバイしている(図8のプロセス1(以下、P1のように記す))。
Similarly, regarding the
そして、次のプロセスで、スタンバイ状態にある上下の金型(1、2)の間隙(キャビティ1aとコア2aの間)に加工素材(繊維強化樹脂素材14a)を挿置する(図8のP2)。
Then, in the next process, the processing material (fiber reinforced
次に、図示しないスライドを動作させ、スライドを全降下する。降下の途上は、一段降下で上下加熱プレート(5、6)を上下金型(1、2)に接触させ、最終的な降下で上下の金型(1、2)に対して互いに押圧する力を与える。これにより、加工素材(繊維強化樹脂素材14a)を挟み、圧縮する(図7Aの(a))。(図8のP3)。
Next, a slide (not shown) is operated to fully lower the slide. During the descent, the upper and lower heating plates (5, 6) are brought into contact with the upper and lower molds (1, 2) in the one-step descent, and the force that presses against the upper and lower molds (1, 2) in the final descent. give. As a result, the processed material (fiber reinforced
そして、上下の加熱プレート(5、6)の加熱手段(カートリッジヒーター)に電流を流して加熱し、加工素材(繊維強化樹脂素材14a)を高温処理する(図7Aの(b):ヒート工程)。(図8のP4)。
Then, an electric current is passed through the heating means (cartridge heaters) of the upper and lower heating plates (5, 6) to heat the processed material (fiber reinforced
なお、前記P3からP4のプロセスに入る時点で、加熱手段(カートリッジヒーター)の事前加熱を行って上下金型(1、2)の温度を予め上昇させておくのが望ましい。 At the time of entering the process from P3 to P4, it is desirable to preheat the heating means (cartridge heater) to raise the temperature of the upper and lower molds (1, 2) in advance.
加工素材の成形に必要とされる所要の時間の経過後、スライドを一段戻して(すなわち、上下ユニット(100、200)が互いに少し離れる)、上下加熱プレート(5、6)への電流を遮断し、上下加熱プレート(5、6)を上下金型(1、2)との接触を断ち、離間させ、上下冷却手段(21、22)に冷却媒体(例えば、0℃~10℃の冷水)を流して加工素材(繊維強化樹脂素材14a)の温度を下げる(図7Bの(c):クール工程)。(図8のP5)。
After the required time required to form the work material, the slides are moved back one step (ie, the upper and lower units (100, 200) are slightly separated from each other) to cut off the current to the upper and lower heating plates (5, 6). Then, the upper and lower heating plates (5, 6) are separated from the upper and lower molds (1, 2), and the upper and lower cooling means (21, 22) are provided with a cooling medium (for example, cold water at 0 ° C to 10 ° C). To lower the temperature of the processed material (fiber reinforced
前記“スライドを一段戻す”とは、それによってユニットバネが伸びて上下の加熱プレート(5、6)は、上下の金型(1、2)との接触が解除されるが、上下の金型(1、2)は、加工素材を挟み込む状態で保持している状態を意味する。
すなわち、上下の金型(1、2)は、依然として加工素材(繊維強化樹脂素材14a)を挟み込んでいる状態を保持している。P5の段階では、加工素材(繊維強化樹脂素材14a)は、挟み込まれた状態であり、その成形状態を保持される。
The above-mentioned "returning the slide one step" means that the unit spring is extended and the upper and lower heating plates (5, 6) are released from contact with the upper and lower molds (1, 2), but the upper and lower molds are released. (1 and 2) mean a state in which the processed material is sandwiched and held.
That is, the upper and lower dies (1, 2) still hold the state in which the processed material (fiber reinforced
上下の冷却手段(21、22)による冷却により、上下の金型(1、2)の温度が所要値(例えば80℃等)に低下した時点で、上下冷却手段(21、22)への冷却媒体の供給を遮断し、スライドを初期位置に戻す。
これにより、上下の金型(1、2)が開き、成形された加工品、すなわち繊維強化樹脂材14が取り出される(脱型される)(図7Bの(d))。(図8のP6)。
When the temperature of the upper and lower molds (1, 2) drops to the required value (for example, 80 ° C.) due to the cooling by the upper and lower cooling means (21, 22), the cooling to the upper and lower cooling means (21, 22) is performed. Shut off the supply of media and return the slide to its initial position.
As a result, the upper and lower dies (1, 2) are opened, and the molded processed product, that is, the fiber reinforced
上記したプロセスを経ることで、加熱圧縮して加工した繊維強化樹脂素材の熱処理(加熱→冷却)に要するサイクルタイムを大幅に短縮することができ、ハイサイクルの生産を実現できる。
これにより、成形品の単価を削減することが可能となり、全体のコスト低減に寄与することができる。
By going through the above process, the cycle time required for heat treatment (heating → cooling) of the fiber-reinforced resin material processed by heating and compression can be significantly shortened, and high-cycle production can be realized.
This makes it possible to reduce the unit price of the molded product and contribute to the overall cost reduction.
