Forming methods for ship structures

Abstract

While FRP molded ship structures offer advantages in terms of strength, productivity, watertightness, and low drag due to their smooth surface, they are disadvantageous in terms of initial costs, materials, and energy when producing multiple sizes of ship structures, as each ship requires a corresponding mold for molding. [Solution] The objective is to form a ship structure using FRP, A mechanism that extends in the longitudinal direction of the ship, It includes a mechanism that extends in the width direction of the ship, A molding die characterized by its ability to accommodate multiple sizes of ship shapes. This will resolve the issue.

Description

Technical Field

[0001] The present invention is used for forming a ship structure made of FRP, and aims to efficiently form ship shapes of multiple sizes.

Background Art

[0002] For the structure of a ship, it is required to reduce costs while ensuring necessary performance. The ship structure formed by FRP molding is excellent in strength, productivity, watertightness, and low resistance due to the smoothness of the surface.

[0003] The ship structure formed by FRP molding exhibits its advantages by integrally molding a molding die corresponding to the ship shape.

Problems to be Solved by the Invention

[0004] Since the aforementioned molding die can only mold one ship shape, it is impossible to mold ship structures of multiple sizes corresponding to market demands.

[0005] Moreover, when molding ship structures of multiple sizes, molding dies corresponding to each ship structure are required, and the manufacturing cost of the molding dies increases.

[0006] Furthermore, when molding ship structures of multiple sizes, molding dies corresponding to each ship structure are required, and the materials and energy for manufacturing the molding dies increase, resulting in a large environmental burden.

Means for Solving the Problems

[0007] The problems are solved by the following molding die described in claim 1.

[0008] Aiming to form a ship structure made of FRP A mechanism that extends in the longitudinal direction of the ship, It includes a mechanism that extends in the width direction of the ship, A mold characterized by its ability to accommodate multiple sizes of ship shapes. [Effects of the Invention]

[0009] According to the present invention, the mold can mold ship structures made of FRP in multiple sizes. Therefore, ships of multiple sizes can be produced according to market demand. In some cases, the cost of manufacturing the mold and the materials and energy used to manufacture the mold can be reduced.

[0010] Furthermore, when molding ship structures of multiple sizes, it is not necessary to use a separate mold for each ship structure, thus reducing the cost of manufacturing the molds.

[0011] Furthermore, when molding ship structures of multiple sizes, it is not necessary to use a separate mold for each ship structure, thus reducing the materials and energy required to manufacture the molds. [Best Mode for Carrying Out the Invention]

[0012] The embodiments (examples) of the present invention will be described in more detail below with reference to the drawings. Figure 1 is a front view of a mold used to form a ship structure from FRP. Figure 2 is a cross-sectional view of a mold used to form a ship structure using FRP (fiber-reinforced plastic). Figure 3 shows multiple forms of molds used to form ship structures using FRP. The specifications of mold 1 are as follows: The dimensions of mold 1 are 12 meters in length and 1 meter in width. Basic structure 2 is part of the components that make up mold 1. The length extension structure 3 is part of the components that make up the mold 1. The width extension structure 4 is part of the components that make up the mold 1. The central extension structure 5 is a part of the components that make up the molding die 1. However, the central extension structure 5 may also be included in the length extension structure 3 or the width extension structure 4. The coupling mechanism 6 is a high-strength bolt. The coupling mechanism 6 has the strength to firmly couple each structure that makes up the molding die 1. The coupling mechanism 6 can be separated and re-coupled by tools. However, a coupling mechanism using pins, latches, or suction by negative pressure may also be used. The connecting mechanism 6 has a positioning function to couple each structure that makes up the molding die 1 to an accurate position. The airtight mechanism 7 is a rubber sealing material. However, if it has airtightness, it may also be made of silicon or resin. The ship structure 8 made of FRP is formed by the molding die 1.

[0013] In FIG. 1, the molding die 1 is composed of the basic structure 2, the length extension structure 3, the width extension structure 4, and the central extension structure 5.

[0014] Also, the ship structure 8 made of FRP is integrally formed using FRP materials by the molding die 1 and has strength, productivity, watertightness, and low resistance due to the smoothness of the surface.

[0015] In FIG. 2, each structure of the molding die 1 is coupled by the coupling structure 6 and has airtightness by the airtight structure 7. However, depending on the molding method of the ship structure 8 made of FRP, it may not have airtightness.

[0016] FIG. 3 is a diagram showing multiple forms of the molding die 1 for forming ship structures 8 made of FRP of multiple sizes.

[0017] The length of the molding die 1 can be changed by changing the number or size of the length extension structures 3 and coupling them.

[0018] Also, the width of the molding die 1 can be changed by changing the number or size of the width extension structures 4 and coupling them.

[0019] Also, by changing the number or size of the length extension structure 3, width extension structure 4, and central extension structure 5 and combining them, both the length and width of the mold 1 can be changed.
