本発明は金属細線よりなる鍔付環状メツシユ体
の成形方法に関するもので、その目的とするとこ
ろはメツシユ体の成形と同時に別に成形した鍔を
メツシユ体と一体に固定せんとするにある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming a flange-shaped annular mesh body made of fine metal wire, and its purpose is to simultaneously form the mesh body and fix a separately formed flange integrally with the mesh body. There it is.
従来金属細線よりなる環状のメツシユ体を防振
支持体として用いる場合は、先ずメツシユ体自体
を成形し、次いでこのメツシユ体に取り付け用の
鍔を溶接又は接着により一体に固定していたが、
溶接又は接着のために手数を要しコストアツプに
なるという欠点があつた。 Conventionally, when an annular mesh body made of thin metal wire was used as a vibration-proof support, the mesh body itself was first molded, and then a flange for attachment was fixed to the mesh body integrally by welding or gluing.
The disadvantage is that welding or adhesion requires labor and increases costs.
本発明はメツシユ体を成形する工程中に於てそ
の内方に別に成形した鍔を一体に固定するように
して従来の欠点を除くようにしたものである。 The present invention eliminates the drawbacks of the conventional mesh body by integrally fixing a separately molded collar inside the mesh body during the process of molding the mesh body.

のある成形品７が得られる。 Next, the method of the present invention will be explained in detail with reference to the accompanying drawings. Reference numeral 1 denotes a tsuba in which the outer periphery of an annular plate is a thin part 1a, which is held concentrically between two divided core metals 2a and 2b as shown in Fig. 1A, with the outer periphery of the tsuba 1 protruding from the outer periphery of the core metal. be. Reference numeral 3 denotes a mesh tube made of thin metal wire knitted and then corrugated, which is fitted onto the outer periphery of the core metals 2a and 2b as shown in FIG.
Place a into a corrugated mesh tube 3. The whole thus formed is fitted into the outer mold 4 as shown in FIG. After fitting and pressing, the mesh tube 3 is compressed as shown in FIG. 1E. In this way, a molded product 6 with a flange 1 inside the middle of the mesh body 3' or a flange 1 on the inside of one side end of the mesh body 3'.
A molded article 7 with a certain color is obtained.
成形品６は第４図の如くモノリス８，９を排気

持部材となつている。 The molded product 6 can be used as a support member for both sides when supporting the monoliths 8 and 9 in the exhaust gas passage 10 as shown in FIG. 4, and the molded product 7 can be used as a support member for the intermediate joint between the monoliths 8 and 9. The collar 1 serves as an exhaust gas sealing member, and the mesh body 3' serves as a vibration-proof support member.
