Detailed Description of the Invention The present invention provides a vibration damping composite steel plate in which a synthetic resin layer having vibration damping performance is interposed between two steel plates, using a bending die with a normal die width of 60 to 1 Qmn+. The bending work used relates to a vibration-damping composite steel plate for bending that can be formed with the same workability.

In order to prevent vibrations generated from structural members or other parts of various machinery, equipment, vehicles, ships, etc., it is necessary to modify the installation foundation of the 91 components themselves, paste them with vibration damping material, or Countermeasures have been taken, such as spraying or coating with a polymer solution that exhibits a vibration damping function.

A vibration-damping composite steel plate is made by laminating a layer of viscoelastic material such as plastic with a 01 to 0.6 tone of 8 degrees between two steel plates each having a thickness of about 1 wn. By forming such a structure, the added vibrational energy is converted into thermal energy at the hook speed through plastic deformation of the viscoelastic material layer, which effectively damps vibrations. .

However, as long as the stiffness and vibration damping composite steel plate is used as it is as a flat sheet material, it exhibits excellent initial effects without any inconvenience. When shaping into this shape, peeling or scratching should be avoided between the layers, which not only prevents the original breakage function from being fully exhibited, but also reduces the appearance.

A conceptual diagram of the operation of a general bending die and a bonding die is shown in FIG. 1, and this will be explained. The plate-shaped object 2 to be processed, which is placed on the bending mold 1 and the soil, is bent as shown by the broken line by a punch B, which is lowered from above, to achieve the intended purpose. This is because the plate-shaped object V is pressed in a straight line with the center section IX as the boundary. To stand up (to stand up)

However, when a composite steel plate for splitting is processed using the above-mentioned method, the extended part of the plate cannot rise up enough at the fulcrum part of the first rule, as shown in Figure 5, and it becomes a broken line. It is easy to create a shape that leaves an angle y with respect to the indicated original position.

As shown in the enlarged view of Fig. 4, when the tip of the punch B contacts the plate-shaped object 2 to be processed and further pressing force is applied, the plate-shaped object 2V is formed by the contact V of the punch tip. Between the central fulcrum and the fulcrums on both sides formed by the edge of the mold, a compressive force (e) moves toward the punch contact area, and an elongation force moves at the same time on the outside, but in a composite steel plate, these opposing effects occur. It is thought that one of the reasons for this is that the entire system cannot fully follow the above.

It is considered that this phenomenon occurs when the shear force of the composite steel plate is small, or when the Young's modulus of the intermediate layer of the composite steel plate is small7.

From this result, if a damping composite steel plate with a Young's modulus of 109 to 10 dny/m is used, it will be 60 to 10 dny/m, which is a relatively narrow category among the dies of commonly used molds.
It turns out that there is no problem in practical use even if it is made from chu.
