本考案は、ラミネート板の折曲げ部の構造に関
するものである。[Detailed Description of the Invention] The present invention relates to a structure of a bent portion of a laminate plate.
最近、自動車等の車両においては、軽量化を図
るために、外板等の部材として、二枚の金属板の
間に樹脂材を介在させて接着積層してなるラミネ
ート板が開発使用されている。 BACKGROUND ART Recently, in order to reduce the weight of vehicles such as automobiles, laminate plates, which are made by laminating two metal plates with a resin interposed between them with adhesive, have been developed and used as members such as outer panels.
ところが、このようなラミネート板では、折曲
げ成形加工時、金属板間に挾まれた樹脂材が塑性
変形することができず、そのために樹脂材に生じ
た内部応力が折曲げ部分の外側の金属板に作用し
てクラツクを発生せしめるという問題があつた。 However, in such laminate plates, the resin material sandwiched between the metal plates cannot be plastically deformed during the bending process, and the internal stress generated in the resin material is caused by the metal on the outside of the bent part. There was a problem that it acted on the board and caused cracks.
本考案はかかる点に鑑みてなされたもので、上

ようにしたラミネート板の折曲げ部の構造を提供
せんとするものである。 The present invention was devised in view of this point, and involves providing a plurality of escape holes in advance in the metal plate inside the portion of the laminate plate to be bent and formed, so that the resin deforms by bending during the bending process. It is an object of the present invention to provide a structure for a bent portion of a laminate plate that can prevent the occurrence of cracks due to internal stress in the resin material by allowing the material to escape through the escape hole.
以下、本考案を図面に示す実施例に基づいて詳

構成されている。 Figure 1 shows the bent part of the laminate plate according to the present invention, and A indicates a resin material 2 such as vinyl chloride resin between two metal plates 1 made of iron, aluminum, etc.
As shown in FIG. 2, the metal plate 1 inside the bent portion of the laminate plate A has a
A large number of circular (for example, 1 to 2 mmφ) relief holes 3,
3, . . . are arranged in a staggered manner, and the resin material 2 deformed by bending is allowed to escape to the outside through the relief holes 3, 3, . . . during the bending process.
次に、上記実施例の作用について説明すると、

防止することができる。 Next, the operation of the above embodiment will be explained.
When bending and forming the laminate plate 1, the metal plate 1 having a large number of escape holes 3, 3,...
Turn the side inside and heat the part to be bent while folding. At that time, the resin material 2 deformed by this bending passes through the numerous escape holes 3, 3,
..., so that no internal stress is generated in the resin material 2, thereby reliably preventing the occurrence of cracks.
