Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an embossed surface of a fitting member such as a trim with a cored bar, which is mounted along the opening edge of an automobile body, in which the cored bar is embossed. The present invention relates to a fitting member with a cored bar, which comprises concealing the uneven surface by pressing a sheet made of the same material as the coating layer on the surface of the fitting member.

<Prior Art> Conventionally, there is a fitting member such as a trim with a cored bar, which is mounted along the edge portion of the body opening of an automobile, as shown in FIG. This is a strip steel core material 1 having a lattice punching.
And a coating material made of a polymer material are co-extruded using a crosshead, a squeeze pattern is formed on one surface of the coating layer body 2a by an embossing roll to give decorativeness, and further, a bender is formed into a U shape. Seal lip 2c
have.

However, the coating layer main body 2a of the conventional fitting member with a cored bar has a problem that an uneven surface 4 in which the cored bar 1 is embossed is formed on the surface and the appearance is impaired. Further, in order to improve this, a decorative skin is attached to the coating layer body 2a by an adhesive, or a plastic sheet having the decorative skin adhered thereto is welded, but the decorative skin or the plastic sheet and its Since it is necessary to prepare a bonding or welding device, there is a problem that the cost increases.

Since the coating layer 2a of the core metal 1 on the seal lip 2c side is covered by the seal lip 2c, the uneven surface is not visible from the outside.

<Problems to be Solved by the Invention> Since the fitting member with a cored bar that is mounted along the edge of the body opening of a conventional automobile has the above-mentioned problems, the cored bar is inserted without a significant increase in cost. It is preferable to easily smooth the surface of the fitting member and improve the appearance.

An object of the present invention is to provide a cored metal fitting member that solves the above problems.

<Means for Solving the Problems> Description will be made with reference to the drawings. In order to achieve the above purpose,
A cored metal fitting member according to the present invention is a fitting member such as a cored metal trim that is mounted along the opening edge of a body of an automobile. The cored metal 1 and a coating layer forming material are substantially U-shaped. A cored metal fitting member formed of a fitting part, a flange clamping claw piece 2d and a seal lip 2c, and a fitting member intermediate product 2 obtained by extrusion molding is molded into a predetermined shape by a bender. In the extrusion process, the seal lip 2c
The back side of the sub-lip 2b formed by branching in the direction opposite to
It is pressure-bonded to the entire surface of the surface side of the coating layer body 2a that covers the core metal 1.

<Function> The outer surface of the coating layer main body 2a having the unevenness obtained by embossing the core metal 1 is surely coated with the smooth sub-lip 2b to be smoothed, and the appearance is improved.

<Example> An example will be described with reference to FIGS. 1 to 5. The core metal 1 is preliminarily bent in a V-shape in cross section by a pre-bender, and the core metal 1 and polyvinyl chloride that have been subjected to the primary bending are preliminarily bent. A cover layer forming material as a main component is co-extruded by a cross bed, and a fitting member intermediate is formed of a substantially U-shaped fitting portion including the coating layer body 2a, a flange holding claw piece 2d, and a seal lip 2c. Make item 2.

The obtained fitting member intermediate product 2 is pressure-bonded to the coating layer main body 2a and the sub-lip 2b in a high temperature state, cooled, and then bent into a U-shaped cross section by a bender, and then an appropriate length in the longitudinal direction. The final product 3 is obtained by cutting into pieces. The outer surface of the obtained final product 3 is covered with the sub-lip 2b, so that it is smooth and has a good appearance. In addition, the thickness of the film outside the core metal 1 of the coating layer body 2a is made as thin as possible, and the total thickness of the film after the sub-lip 2b is pressure-bonded thereon is set to the conventional thickness, Compared to the ones, the cost increase can be kept very small.

<Effect of the Invention> The present invention is smooth and has a good appearance because the outside of the final product 3 obtained as described above is covered with the sub-lip 2b. Further, the thickness of the film on the outside of the core metal 1 of the coating layer body 2a is made as thin as possible, and the total thickness of the film after the sub-lip 2b is pressure-bonded thereon is set to the conventional thickness. Compared to the ones, the cost increase can be kept very small. Since the uneven surface of the core metal coating layer 2a on the seal lip 2c side is covered with the seal lip 2c, it is not visible from the outside.

In the present invention, the equipment and work required for crimping slightly increase, but the required amount of coating layer forming material does not increase, and the cost is slightly increased, the surface of the trims is smoothed, and the appearance is improved. Remarkably improved.
