Description

TECHNICAL FIELD [0001] The present invention relates to a damper for a fuel tank pipe, a method for manufacturing the damper, and a damper manufactured by the method, and a fuel tank pipe for a vehicle having the damper.

The present invention relates to a damper for a fuel tank pipe, a method of manufacturing a damper, and a damper manufactured by the method, which can improve the convenience of assembly in assembling a damper to a fuel tank pipe, To a fuel tank pipe for a vehicle.

2. Description of the Related Art Generally, an engine of a vehicle is a device that converts thermal energy into mechanical rotational force by rotating a crankshaft using an explosive force generated by burning fuel in a combustion chamber.

In such an engine, a fuel to be burned in the combustion chamber is continuously supplied, and a fuel tank capable of storing a predetermined amount of fuel is provided in the vehicle for fuel supply.

As shown in FIG. 1, various types of fuel tank pipes 10 such as a fuel pump pipe connected to a fuel pump, a valve pipe connected to a valve type, a return pipe, and the like are coupled to the fuel tank 1 of the vehicle.

The fuel tank pipe 10 is installed in close contact with the fuel tank 1 in order to avoid interference with surrounding components. Therefore, the noise generated due to the collision with the fuel tank 1 In order to prevent vibration and further prevent the decrease in durability of the fuel tank pipe 10, the damper 20 is used by being coupled to the fuel tank pipe 10 as shown in Fig.

The damper 20 is a pipe-shaped material having a predetermined length and has a cushion like a sponge. The operator assembles the damper 20, which is manufactured separately, by inserting the damper 20 into the fuel tank pipe 10, 20 has a disadvantage in that the workability is poor and the assembling time is long and the productivity is slowed down.

In order to fix the position of the damper 20 fitted to the fuel tank pipe 10, a liquid-type adhesive 30 is applied to both ends of the damper 20 to be coupled with the fuel tank pipe 10.

However, if the damper 20 is coupled to both ends of the damper 20 using the adhesive 30, the coupling force of the damper 20 is rapidly weakened due to the continuous vibration. In a severe case, It is not possible to perform the function as a damper.

In addition, there is a disadvantage in that the working time is lengthened by the time required until the adhesive 30 of the liquid applied to both ends of the damper 20 is completely cured.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.

The first damper portions 51 and 61 and the second damper portions 52 and 62 are made of a flexible cushion material and are chemically stable and have excellent weatherability and ozone resistance. Diene Monomer) is preferably used as a raw material, but it is not limited thereto.

As the pressure-sensitive adhesive (53, 63) passes through the drying path described later as a liquid component, only the component of the pressure-sensitive adhesive remains, thereby enhancing the adhesiveness and strengthening the bonding force with the release papers (54, 64).

The pressure sensitive adhesives 53 and 63 are provided on the inner surfaces 51a and 52a of the first and second damper portions 51, 52, 61 and 62 for the purpose of strengthening the coupling force of the first and second damper portions 51, , 61a, 62a and thickness planes 51b, 52b, 61b, 62b.

The releasing papers 54 and 64 are molded together when the first damper portions 51 and 61 and the second damper portions 52 and 62 are molded. For this purpose, PET (Polyethylene Terephthalate) But it is not limited thereto.

The first damper portions 51 and 61 and the second damper portions 52 and 62 are formed in the shape of a semicircular cross section along the circumferential direction of the fuel tank pipe 10, As shown in FIG.

As described above, since the first damper portions 51 and 61 and the second damper portions 52 and 62 are connected to each other through the connection sections 55 and 65, the first damper portions 51 and 61, The first damper portions 51 and 61 and the second damper portions 52 and 62 are completely separated from each other when the two damper portions 52 and 62 are coupled to the fuel tank pipe 10, There is also an advantage in that the risk of loss can be reduced.

The first damper portions 51 and 61 and the second damper portions 52 and 62 are formed in the same shape as a portion of the fuel tank pipe 10 along the longitudinal direction of the fuel tank pipe 10 So that the first damper portions 51 and 61 and the second damper portions 52 and 62 can be more easily engaged with each other than when the first damper portions 51 and 61 and the second damper portions 52 and 62 are coupled to the fuel tank pipe 10,

When the first damper portion 51 and the second damper portion 52 are formed in the damper distal end 73 through the press molding machine 76, the release paper 54 coupled to the damper distal end 73 is also pressed against the first damper portion 51 and the second damper portion 52. For this purpose, the release paper 54 is preferably made of PET, which has good moldability and does not break during press forming .

The damper raw material 73 in which the first damper portion 51 and the second damper portion 52 are molded is machined by the press cutter 77 having the blade 77c and the press cutter 77 The blade 77c cuts all the outer rims of the first damper portion 51 and the second damper portion 52 except for the connection section 55 so that the first damper portion 51 And the second damper portion 52 can be separated from the damper raw end 73, thereby finally completing the manufacture of the damper 50.

4, the first damper unit 51 and the second damper unit 52 are connected to the damper 50 having a straight line shape along the longitudinal direction of the fuel tank pipe 10, Or the first damper portion 61 and the second damper portion 62 are formed in a shape in which the straight line section 67 and the curve section 68 are combined along the longitudinal direction of the fuel tank pipe 10 as shown in FIG. The damper 60 of FIG.

The damper 50 formed in a straight line is coupled to the straight section of the fuel tank pipe 10 and the damper 60 in which the straight section 67 and the curved section 68 are combined is disposed in the curved section of the fuel tank pipe 10 .
