Description

[Detailed Description of the Invention] A. Field of Industrial Application Does the present invention have the ability to manufacture Sand Inoji metal strips? ):! Regarding ζ, details, < is a Santoi 7chi structure with a resin film as the core material and metal plates on both sides, which improves vibration damping performance and improves the vibration damping performance It depends on the manufacturing method.

BACKGROUND OF THE INVENTION In conventional automobiles and the like, it is often necessary to use so-called damping materials in order to reduce vibrations of parts.

For these various uses, Zandisochi metal plate (2), which has a resin film as the core material and metal plates on both sides! ! l river is being considered.

Also, is the above-mentioned 1-utζ sandwich gold metal plate used in automobile production? ) No need to try press forming on a mass production line like this! ! From the viewpoint of improving productivity, it is desirable to continuously supply the raw material sand/inochi metal plate from the coiled state.

However, in the case where the IJ' switch metal plate is used for one purpose, especially the vibration damping performance, the resin as the core material has a glass transition point near the temperature of '1〒; Moreover, the adhesion to the metal plates on both sides is not strong.

For this reason, by coiling the conventional sand metal plate and using the sand metal plate, it is possible to prevent the misalignment between the double-faced metal plates of the 4J metal band when winding, unwinding, flattening and straightening the coil. , 1-ri;r:IIpint may occur, or the adhesive force between the resin and the inner skin metal plate may decrease, making it impossible to withstand press-forming using sandwich metal strips as a material. However, there is a drawback that it is difficult to convert a conventional sandwich metal strip into a coil (HA) for press molding.

C. Purpose of the Invention The present invention provides a vibration damping Santoi 7/Senkin bottom plate which has a resin film as a core material and has metal plates on both sides.
The resin film as the core material 2 is used together with the main resin film that has excellent vibration damping performance, and in some parts, JIAI oil cavity 71-71 is made with adhesive 11 old 1-te which has strong adhesive strength and deformation resistance. By setting the coil, there are two winding and unwinding operations.

Misalignment of the inner skin metal plate of the sandwich metal band that occurs during flattening correction. By preventing FSI, the occurrence of wrinkles during press forming is significantly reduced, and the press formability is improved. '! ＋Extends the strength of the sandwich metal strip that can be painted (J(
Sui 1 is 1-'I 7.

2. The structure and operation of the invention are as follows: 1. According to the present invention, a Santoi, which has a resin film as a core material 7 and metal plates on both sides thereof,
A method for manufacturing a 1,000 metal strip continuously and winding it into a coil shape, which involves winding and unwinding the continuously manufactured 7 coils. , In order to prevent misalignment and peeling between the metal plates on one screen even during flattening correction,
A resin film as a core) and (with a main resin film with excellent distribution performance are partially juxtaposed with an adhesive resin film having stronger LF adhesion and resistance than the main 441 resin film. ,
This is achieved by the method of manufacturing 1,000 gold coins.

E Example Examples of the present invention are described below based on the attached 171 pages.

explain.

FIG. 1 is an external view of a Sando Inno metal strip coil manufactured by the method of the present invention.

As is clear from the figure, the Santoi and Senkin bottom metal manufactured by the method of the present invention have main resin films 2.2a, 21'+ 20 with excellent vibration damping performance and an adhesive resin film between the skin metal plates 1 and 3o). 4.4a and 4b are distributed in the widthwise direction, forming a sandwiched Santoi Nochi metal band.

In addition, in this embodiment, the adhesive resin films 4.4a and 4b are as follows:
Although it has a strip shape in the longitudinal direction, the effect of the present invention remains unchanged even if it is placed in a continuous egg).

FIG. 2 is a schematic diagram illustrating the manufacturing process of a Santoy No-T metal strip by the method of the present invention.

After unwinding the skin metal material 11.11a of the sandwich metal band, shearing it with a double cut shear 13.13a,
Manosh Seemura -) Reda 14.14a, each continuous band is laminated at one place along with the main resin film material 12 of the core material and the adhesive 11ti I material + A12a via the roots, Then, the C-trol 22 sends the product as one piece to the crimping unit 6.

Note that the guide 23 is made of both resin film elements + A12. ．． This is to position I2a in the width direction.

Adhesion t, AI resin + II 21 is Guy 1? At one point in time, the main resin film material 12 needs to be disposed at 100" positions in the width direction and divided, but the main resin film material 12 may be in a continuous state.

At this time, apply a buff tension to the four strip plates and the resin film material of 10.
Place the material under tension.

Then, red eyes! +1 addition!゛; It is fed into the furnaces 15a and 15b.

First, the main resin films 2.2a, 2b are heated in a preheating furnace I5:1.
, 2c or higher, and the adhesive resin 11';! 4.4
After being heated to a temperature that provides sufficient deformation resistance, the adhesive resin films 4.4a and 4b are bonded to the double-sided skin metal plates 1 and 3 by applying light pressure with the prepress roll 24, and the main resin The excess of membranes 2.2a, 2b, 2C is removed.

Thereafter, after heating in a heating furnace 15) until both resin films are melted and their viscosities are relatively similar, the chin 1 is
