Description

The present invention relates to a method of manufacturing a wire mesh filter with gasket, more particularly, to a motor vehicle, industrial machinery, a method for manufacturing a wire mesh filter with gasket which is widely used in household appliances stove, etc. .

  Conventionally, a gasket with a wire mesh filter is manufactured by a method in which a fine hole (mesh) is formed in a thin metal plate by pressing, and a rubber elastic material gasket is integrally formed on the outer periphery of the thin metal plate in which the fine hole (mesh) is formed. Was.

  For this reason, it is expensive to form fine holes (mesh) in the metal thin plate by pressing, and at the same time, an adhesive is applied to the surface of the metal thin plate in order to integrate the metal thin plate and the rubber elastic material gasket. It took time to do.

  In particular, in the step of applying the adhesive to the surface of the metal thin plate, a method of immersing the entire metal thin plate in the adhesive bath is desirable from the viewpoint of work efficiency, but the adhesive has caused a problem of blocking the fine holes.

  For this reason, the method of applying an adhesive to the surface of a thin metal plate has to be taken by brushing, which is a manual operation, and the working efficiency is greatly reduced.

  An object of the present invention is to reduce the manufacturing cost and to provide a highly reliable gasket with a wire mesh filter at low cost by eliminating the need for applying an adhesive.

In order to achieve the above object, in the present invention, a step of directly forming an annular polyamide resin layer on both surfaces of a wire mesh and an annular rubber elastic material gasket on the outside of the polyamide resin layer are integrally formed. The manufacturing method of the gasket with a metal-mesh filter including the process and the process of punching the said metal mesh located in the outer peripheral side of the said gasket cyclically | annularly along the outer peripheral surface of the said gasket is characterized.

The present invention has the following effects.
According to the method for manufacturing a gasket with a wire mesh filter according to the first aspect of the invention, the manufacturing cost can be kept low, and a highly reliable gasket with a wire mesh filter can be provided at low cost.
Furthermore, according to the manufacturing method of the gasket with a wire mesh filter of the invention of claim 2 , the wire mesh can be continuously produced by using a material wound in a roll shape, and can be produced at a lower cost. .

The top view of the gasket with a wire-mesh filter obtained by this invention. AA sectional drawing of FIG. The top view of the wire mesh used for manufacture of the gasket with a wire mesh filter of this invention. The figure which integrally molded the cyclic | annular polyamide resin layer in the wire mesh of FIG. The figure which integrally molded the rubber-made elastic material gasket on the outer side of the polyamide resin layer of FIG.

Hereinafter, the best mode for carrying out the present invention will be described.
As shown in FIGS. 1 and 2, a gasket 4 with a wire mesh filter obtained by the present invention comprises a disk-shaped wire mesh 1 and an annular rubber elastic material gasket 2 integrally formed on the outer periphery of the wire mesh 1. It has a basic configuration.
The gasket 2 is integrated with the wire mesh 1 via an annular polyamide resin layer 3.

As shown in FIG. 2, the polyamide resin layer 3 is integrated with the wire mesh 1 in such a manner that the wire mesh 1 is sandwiched between the front and back surfaces of the wire mesh 1.
The rubber-like elastic material gasket 2 has a U-shaped cross section so as to wrap around the outer peripheral side of the polyamide resin layer 3.
The wire mesh 1 exists so as to cross the polyamide resin layer 3 and the rubber-like elastic material gasket 2.

The polyamide resin is a linear polymer having an amide bond repeating unit, and typical nylon resins include 6 nylon, 6, 6 nylon, and the like.
This kind of polyamide resin can be directly integrated with a wire mesh or a metal thin plate without an adhesive, and can be directly integrated with a rubber-like elastic material without an adhesive, so that an adhesive treatment process can be omitted.
For this reason, while keeping manufacturing cost low, the highly reliable gasket 4 with a wire mesh filter can be provided at low cost.

Further, by including an adhesive additive component in this type of polyamide resin layer 3, it is possible to further increase the adhesive force with a wire mesh or a rubber-like elastic material.
For this reason, it can be set as the gasket 4 with a wire-mesh filter with higher reliability.

  Rubber-like elastic materials used for the gasket 2 include ethylene propylene diene terpolymer (EPDM), fluorine rubber (FKM), water-added nitrile rubber (HNBR), nitrile rubber (NBR), and natural rubber (NR). Acrylic acid ester rubber (ACM) or the like is appropriately selected and used.

Next, the manufacturing method of the gasket 4 with a wire mesh filter according to the present invention will be described with reference to FIGS.
First, a wire mesh 1 as shown in FIG. 3 is prepared. The wire mesh 1 is not subjected to any adhesive treatment.
Further, by using the wire mesh 1 as a material wound in a roll shape, continuous production becomes possible and production can be performed at a lower cost.

Next, as shown in FIG. 4, an annular polyamide resin layer 3 is directly integrally formed on both surfaces of the wire mesh 1.
Usually, the polyamide resin layer 3 can be easily provided on both surfaces of the metal mesh 1 by using a mold and utilizing injection molding.

  Next, as shown in FIG. 5, an annular rubber-like elastic material gasket 2 is integrally formed outside the polyamide resin layer 3.

  Finally, by punching the wire mesh 1 located on the outer peripheral side of the gasket 2 in a ring shape along the outer peripheral surface of the gasket 2, a gasket 4 with a wire mesh filter shown in FIGS. 1 and 2 is obtained.

  Thus, since the adhesive treatment process can be omitted, the manufacturing cost can be kept low, and a highly reliable gasket with a wire mesh filter can be provided at low cost.

  The present invention is not limited to the best mode for carrying out the invention described above, and various other configurations can be adopted without departing from the gist of the present invention.

  The gasket with a wire mesh filter according to the present invention is widely used in household equipment such as automobiles, industrial machinery, and gas stoves.
