Abstract

PURPOSE:To avoid the protrusion of a reinforcing iron plate to the mold portion during the vulcanization period by biasing by interleaving a rubber spacer between the reinforcing iron plate to be buried into a rubber fender and the mold. CONSTITUTION:Plural spacers 6 are set around a mold 4, and a reinforcing iron plate 5 is set around the spacer 6 made of a semi-vulcanized rubber or a rubber chip with a fixed interval between the iron plate 5 and the mold 4 corresponding to an opening. A rubber is charged into the mold. The insertion of the spacer 6 can completely prevent the protrusion of the reinforcing iron plate 5 into the opening by biasing during the vulcanization period.

である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a rubber fender, and in particular to a method for manufacturing a rubber fender, in which a reinforcing iron plate is embedded inside which can prevent the reinforcing iron plate from being exposed to an opening. This relates to a manufacturing method.

ことによって取り付けられるのが一般的である。When a ship berths, fenders are used to absorb the berthing energy of the ship and prevent damage to the ship's hull. This fender is generally attached by fixing its flange to the quay surface with screws or tools.

口部に補強用鉄板が露出することとなる。When manufacturing fenders, these reinforcing iron plates are placed in advance at predetermined positions within the entire mold, and then rubber is charged into the mold. At this time, the position of the reinforcing iron plate placed in the mold shifts, and when the fender is removed from the mold, the reinforcing iron plate is exposed at the opening of the fender.

は極めて低（なってしまう。If you use a fender with reinforcing iron plates exposed in the openings, there is a risk that the exposed parts will corrode, and this will progress to the entire surface of the iron plate, causing the rubber to peel off and the rubber body to be missing. This will obstruct the insertion of the fittings into the wood, and the commercial value will be extremely low.

防舷材の製造方法を提供することにある。However, it is an object of the present invention to provide a method of manufacturing a rubber fender in which a reinforcing iron plate is embedded, which can prevent the reinforcing iron plate from being exposed to the opening.

される。According to the present invention, a step of arranging a spacer member around a mold part for forming an opening in a rubber fender, a step of arranging a reinforcing steel plate around the spacer member, and a step of placing rubber into the mold. Provided is a method for manufacturing a rubber fender in which a reinforcing iron plate is embedded, the method comprising the steps of:

以下添付の図面を参照して本発明の好ましい実施例につ
いて説明する。Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

一体的に形成された環状フランジ３から成る。FIG. 1 is a sectional view of an example of a conventionally well-known fender. The fender shown in Fig. 1 includes a hollow truncated conical bearing part 1 and an integrally formed cylindrical bearing part extending from the small diameter end of the bearing part 1 in a direction parallel to the axis. It consists of an abutment part 2 and an annular flange 3 integrally formed extending from the large diameter end of the support part 1 along a plane perpendicular to the axis.

目をなす。A reinforcing iron plate 5 is embedded inside the annular flange 3. Further, a reinforcing iron plate 5 is buried inside the top surface of the receiving part i and i if necessary. This reinforcing iron plate 5 not only imparts rigidity to the top surface of the impact receiving section 2, but also serves as a mounting board when a larger area of impact receiving plate material is attached on the top surface of the impact receiving section 2.

む。FIG. 2 shows a mold portion 4 corresponding to the opening of the fender, and according to the method of the present invention, a plurality of spacer members 6 are first arranged around the mold portion 4. Preferably, the spacer member 6 is composed of semi-vulcanized rubber, a strip or a rubber chip. Next, a reinforcing iron plate 5 is placed around the spacer member 6 to maintain a constant distance between the iron plate 5 and the mold portion 4 corresponding to the opening. After that, the rubber is charged into the mold.

へ露出することは完全に防止される。FIG. 3 shows a cross section of the opening of a fender manufactured by the method of the present invention comprising such steps. As can be easily understood from FIG. 3, by arranging the spacer member 6 in advance in the mold, the reinforcing iron plate 5 is completely prevented from shifting during vulcanization and being exposed into the opening.
