Description
本発明は、自動車車体等に取付けられるアルミ箔等の金属箔付きインシュレータの加熱圧縮成形方法に関する。 The present invention relates to a heat compression molding method for an insulator with a metal foil such as an aluminum foil attached to an automobile body or the like.
インシュレータの加熱圧縮成形方法に関する従来技術としては特許文献１内に述べられているようなものがある。
しかし、従来のインシュレータの加熱圧縮成形方法では該インシュレータに含浸させた未硬化のフェノール樹脂等の熱硬化性樹脂の全体を熱硬化させているため成形後の該インシュレータははなはだ硬く、自動車車体等に取付ける際に柔軟性を期待できないので予め所定の形状に合うように成形せざるを得なかったが、特にエンジンルーム内に用いられエンジンからの熱輻射を遮るために金属箔を貼着したものでは圧縮成形時に無理な変形を強いられて該金属箔が破れてしまうという欠点があった。 However, in the conventional heat compression molding method of an insulator, the entire thermosetting resin such as an uncured phenol resin impregnated in the insulator is thermoset, so that the insulator after molding is very hard and is not suitable for an automobile body or the like. Since flexibility cannot be expected when mounting, it had to be molded to fit a predetermined shape in advance, but in particular it was used in the engine room and stuck with metal foil to block heat radiation from the engine There was a drawback that the metal foil was torn because of forced deformation during compression molding.
例えば図１に示すような、Ａ部やＢ部が直角に折れ曲がったアルミ箔付きインシュレータの場合、グラスウール１の表面にアルミ箔２が貼着されているが、圧縮成形の際に特に該Ｂ部の該アルミ箔２は曲げによって大きく伸ばされるため亀裂が入ってしまうことが多かった。 For example, in the case of an insulator with an aluminum foil in which the A part and the B part are bent at a right angle as shown in FIG. 1, the aluminum foil 2 is adhered to the surface of the glass wool 1, but the B part is particularly used during compression molding. Since the aluminum foil 2 was greatly stretched by bending, it often cracked.
解決しようとする課題は、グラスウールの表面にアルミ箔等の金属箔が貼着されているインシュレータを直角に折り曲げて圧縮成形するような場合、
特にエンジンルーム内に用いられエンジンからの熱輻射を遮るために金属箔を貼着したものでは圧縮成形時に無理な変形を強いられて該金属箔が破れてしまう、即ち
該金属箔が曲げによって大きく伸ばされるため亀裂が入って
熱輻射を完全には遮ることができなくなる
という点である。本発明は上記の点を解決するためになされた。
The problem to be solved is a case where an insulator in which a metal foil such as an aluminum foil is adhered to the surface of glass wool is bent at a right angle and compression molded.
In particular, in a case where a metal foil is used to block heat radiation from the engine used in an engine room, the metal foil is torn by being forcedly deformed during compression molding, i.e., the metal foil. Cracks because it is greatly stretched by bending
The heat radiation cannot be completely blocked . The present invention has been made to solve the above-described points.
本発明は、アルミ箔等の金属箔付きインシュレータの加熱圧縮成形方法において、グラスウールに含浸可能な未硬化の熱硬化性樹脂を含浸させた金属箔付きグラスウール原反の折り曲げ予定線の近傍を非加熱領域とし、
熱源付き金型の該非加熱領域に相当する部分を逃がし、両者を非接触として、
該非加熱領域を除いた加熱領域のみを加熱しながらプレスし、その後該金属箔付きグラスウール原反を所望の形状にトリムすることを最も主要な特徴とする。
The present invention relates to a method for heat compression molding of an insulator with a metal foil such as an aluminum foil, in which the vicinity of the planned bending line of the glass wool original fabric with the metal foil impregnated with an uncured thermosetting resin impregnated into the glass wool is not heated. Area and
Let the part corresponding to the non-heated area of the mold with a heat source escape,
The main feature is that only the heated region excluding the non-heated region is pressed while being heated, and then the glass wool original fabric with metal foil is trimmed to a desired shape.
本発明によれば自動車車体に取付ける必要上、直角に折れ曲がった形状のインシュレータであっても圧縮成形時には平坦形状のままで成形するため、グラスウールの表面に貼着された金属箔には伸展負荷がかからず、該金属箔が破れることはない
ので、自動車車体等の特にエンジンルーム内に用いてもエンジンからの熱輻射を完全に遮ることができる
という利点がある。
According to the present invention, an insulator bent to a right angle is required to be attached to an automobile body, and is formed in a flat shape at the time of compression molding, so that the metal foil adhered to the surface of glass wool has an extension load. Does not take, the metal foil is not torn
Therefore, there is an advantage that heat radiation from the engine can be completely blocked even when used in an engine room such as an automobile body .
自動車車体に取付ける必要上、直角に折れ曲がった形状の金属箔付きインシュレータを成形する際に該金属箔に亀裂が入らないようにする
ことで、自動車車体等の特にエンジンルーム内に用いてもエンジンからの熱輻射を完全に遮る
という目的を、グラスウールに含浸可能な未硬化の熱硬化性樹脂を含浸させた金属箔付きグラスウール原反の折り曲げ予定線の近傍を非加熱領域とし、
熱源付き金型の該非加熱領域に相当する部分を逃がし、両者を非接触として、
該非加熱領域を除いた加熱領域のみを加熱しながらプレスし、その後該金属箔付きグラスウール原反を所望の形状にトリムすることによって、コストアップを招かずに実現した。
Because it is necessary to attach to the automobile body, when forming an insulator with a metal foil bent at a right angle, make sure that the metal foil does not crack.
Therefore, metal foil impregnated with uncured thermosetting resin that can be impregnated into glass wool for the purpose of completely blocking heat radiation from the engine even when used in an engine room such as an automobile body. The vicinity of the bending line of the glass wool original fabric with a non-heated area,
Let the part corresponding to the non-heated area of the mold with a heat source escape,
By pressing only the heating area excluding the non-heating area while heating, and then trimming the glass wool original fabric with metal foil into a desired shape, the cost was not increased.
図２は、本発明の１実施例を示すアルミ箔付きグラスウール原反５のプレス後の斜視図である。該アルミ箔付きグラスウール原反５には未硬化のフェノール樹脂が含浸されている。３，３は折り曲げ予定線。４，４は非加熱領域を示す。 FIG. 2 is a perspective view after pressing the glass wool original fabric 5 with an aluminum foil showing one embodiment of the present invention. The glass wool original fabric 5 with aluminum foil is impregnated with uncured phenol resin. 3 and 3 are fold lines. Reference numerals 4 and 4 denote non-heated regions.
次に本発明の作用を説明する。プレス（図示せず）に取付けられた熱源付き金型（図示せず）に該アルミ箔付きグラスウール原反５をセットし、該非加熱領域４，４を除いた加熱領域７，７，７を加熱しながらプレスする。 Next, the operation of the present invention will be described. The glass wool original fabric 5 with aluminum foil is set in a mold (not shown) with a heat source attached to a press (not shown), and the heating regions 7, 7, 7 excluding the non-heating regions 4, 4 are heated. While pressing.
該非加熱領域４，４を非加熱とする具体的な手段としては該熱源付き金型の該非加熱領域４，４に相当する部分を逃がし、両者を非接触とすれば良い。 As a specific means for making the non-heated regions 4 and 4 unheated, a portion corresponding to the non-heated regions 4 and 4 of the mold with the heat source is allowed to escape so that the two are not in contact with each other.
次に該アルミ箔付きグラスウール原反５を所望の形状６にトリムする。 Next, the glass wool original fabric 5 with aluminum foil is trimmed to a desired shape 6.
図３は該アルミ箔付きグラスウール原反５のトリム後の成形品を表す。該加熱領域７，７，７は加熱されているために未硬化の該フェノール樹脂が硬化して剛性が高いが、該非加熱領域４は加熱されていないために該フェノール樹脂は未硬化のままなので剛性は低い。 FIG. 3 shows a molded product after trimming the glass wool original fabric 5 with aluminum foil. Since the heating regions 7, 7, and 7 are heated, the uncured phenol resin is cured and has high rigidity, but since the non-heated region 4 is not heated, the phenol resin remains uncured. The rigidity is low.
従って該インシュレータを自動車車体に取付ける際、該折り曲げ予定線３は自在に屈曲するために容易に作業を行なうことが出来る。 Therefore, when the insulator is attached to the automobile body, the planned bending line 3 can be easily bent, so that the work can be easily performed.
以上実施例に述べたように本発明によれば、自動車車体に取付ける必要上、直角に折れ曲がった形状のインシュレータであっても圧縮成形時には平坦形状のままで成形するため、グラスウールの表面に貼着されたアルミ箔には伸展負荷がかからず、該アルミ箔が破れることはないという効果がある。 As described above in the embodiments, according to the present invention, it is necessary to attach to an automobile body, and even an insulator bent in a right angle is molded in a flat shape at the time of compression molding. There is an effect that the applied aluminum foil is not subjected to an extension load and the aluminum foil is not torn.
尚、本実施例ではアルミ箔を用いた例を述べたが、銅箔や錫箔等他の金属箔を用いても良い。 In this embodiment, an example using an aluminum foil has been described. However, other metal foils such as a copper foil and a tin foil may be used.
また、フェノール樹脂の代わりにユリア樹脂やメラミン樹脂等のグラスウールに含浸可能な他の熱硬化性樹脂を用いても良い。 Moreover, you may use the other thermosetting resin which can be impregnated into glass wool, such as a urea resin and a melamine resin, instead of a phenol resin.
本発明は、自動車車体等の相手部品に取付ける必要上、直角に折れ曲がった形状の金属箔付きインシュレータの加熱圧縮成形に利用可能である。 INDUSTRIAL APPLICABILITY The present invention can be used for heat compression molding of an insulator with a metal foil that is bent at a right angle because it needs to be attached to a counterpart part such as an automobile body.
