Description

TECHNICAL FIELD [0001] The present invention relates to a high pressure vessel manufacturing apparatus,

The present invention relates to an apparatus for manufacturing a high-pressure vessel, and more particularly, to an apparatus for manufacturing a high-pressure vessel for use in a hydrogen fuel cell automobile or a CNG automobile.

Natural gas cars require fuel storage containers and fuel cell vehicles require high pressure vessels such as hydrogen tanks.

Such high-pressure vessels are conventionally made of metallic materials. The cylindrical high-pressure vessel using the conventional metallic material is manufactured by welding the body, the upper plate body, and the lower plate body, or by welding the upper plate body to the body formed by deep drawing, It is a structure that secures strength safety.

However, high-pressure vessels using metallic materials are heavy in weight, very vulnerable to corrosion, and expensive to manufacture. On the other hand, the high-pressure vessel using polymer resin is light and resistant to repeated fatigue, and has a short gas filling time.

Accordingly, in order to reduce the weight, a high-pressure vessel is often fabricated by using a polymer resin such as high-density polyethylene (HDPE), and the demand thereof is increasing.

However, the present situation is not provided with an apparatus for effectively manufacturing a high-pressure vessel using such a polymer resin.

Therefore, a manufacturing apparatus suitable for manufacturing a high-pressure vessel made of a polymer resin material is required.

At this time, the first dome clamp unit 2 slides along the guide bar 131 and the dome clamp guide bar 24. Accordingly, the first dome clamp section 2 approaches or moves away from the first pipe clamp section 11. [

In this way, two screws can be driven by one motor using a belt. In addition, since the two screws are driven by a single motor, synchronization can be smoothly performed.

Accordingly, the first dome clamp unit 2 can be moved relative to the first pipe clamp unit 11.

The second dome clamp section 3 also has the same structure as the first dome clamp section 2 and is moved relative to the second pipe clamp section 12 by driving of the motor 35 It is possible.

The dome D1 and the dome D2 are coupled to the coupling guide 85 of the dome loader 8 while the protrusion DE is engaged with the coupling chuck 85 to be fixed in the space inside the protrusion DE . Accordingly, the positions of the dome (D1, D2) can be aligned with each other before clamping the dome clamps (2, 3).

The dome loader may be used for the high-pressure vessel in which the protrusion is formed, but in the case of the high-pressure vessel without the projection, a jig capable of fixing the dome or a dome loader of vacuum adsorption type may be used.

The dome is fixed to the dome loader 8 and then fixed to the dome clamps 2 and 3 but the dome D1 and D2 are placed on the jig etc. in addition to the dome loader 8 and the dome clamps 2 and 3 ).

Next, the process of cutting and melting the edges of the two dams (D1, D2) and the pipe (P) proceeds.

First, as shown in Fig. 6 (b), the cutting units 4 and 5 are moved between the pipe P and the dome D1 and D2.

The dome clamp portions 2 and 3 and the cutting portions 4 and 5 are moved to the pipe clamp portion 1 when the cutting portions 4 and 5 are completely moved. At this time, the cutter 52 of the cutting portion is in a rotating state.

As a result, the rim of the dome D1 or D2 and the rim of the pipe P which are in contact with the cutter 52 of the cutting portion are cut and become a smooth surface as shown in Fig. 6 (c).

The edges of both ends of the pipe P and the edges of the dams D1 and D2 are smoothly processed so that the pipe P and the dome D1 and D2 are well joined in a process to be described later. In addition, since the dome and the pipe P are cut to a predetermined length, the high-pressure vessel can be made to have a predetermined size.

6 (d), the dome clamp portions 2 and 3 and the cutting portions 4 and 5 are returned to their original positions.

Next, as shown in FIG. 6 (e), the heating plates 62 and 72 of the heating units 6 and 7 are moved between the pipe P and the dome D1 and D2.

When the movement of the heating plates 62 and 72 is completed, the dome clamp units 2 and 3 and the heating plates 62 and 72 move to the pipe clamp unit 1. [ At this time, the heating plates 62 and 72 are heated by the heaters 61 and 71.

As a result, the rim of the dome (D1, D2) and the rim of the pipe (P), which are in contact with the heating plates (62, 72), are heated and melted as shown in FIG. 6 (f).

As a result, the rim of both ends of the pipe P and the rims of the dome D1 and D2 of the pipe P are melted and become mutually connectable.

Next, the dome clamps 2 and 3 and the heating units 6 and 7 return to their original positions.

As a result, the melting operation is completed and the state shown in Fig. 6 (g) is reached.

Next, the operation of joining the two domes to the pipe P proceeds simultaneously.

The dome clamps 2 and 3 are moved as shown in FIG. 6 (h) so that the rim of the molten domes D1 and D2 comes into contact with the rim of the pipe P.

Next, it is cooled in the air for 10 to 15 minutes in this state.

Thus, the cooling operation is completed and the state shown in Fig. 6 (i) is reached, and the product is completed through post-treatment such as removal of foreign matter.

Since the operation of joining the two side dome (D1, D2) to the pipe (P) is performed at the same time, it is possible to complete the high pressure vessel product easily and quickly.
