Description

[0001] Apparatus for forming curved plate [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curved plate forming apparatus, and more particularly, to a curved plate forming apparatus capable of easily adjusting an interval from a base member to a pressing surface for applying pressure to a workpiece.

In recent years, demand for mooring vessels for transporting liquid gas has been increasing due to the surge in consumption due to high oil prices and reactor accidents. On the other hand, a liquid gas carrier is a ship that transports liquid gas from a production base to a receiving base. It is usually called an "LNG" or "LPG" depending on the type of liquid gas.

In addition, a storage tank for storing the elang- ey or the lypzie is provided on the elongation line or the el- lipy line, and such a storage tank is generally formed into a double-structured sphere.

In addition, the spherical storage tank is formed by welding a plurality of aluminum plate patches formed with a predetermined curvature to maintain the spherical shape.

Therefore, dimensional control of the curvature is considered to be a very important factor in the manufacture of spherical storage tanks.

Furthermore, since the cooling rate of the curved plate necessary for manufacturing the spherical storage tank is low, it takes a long time to form the curved plate, which lowers the manufacturing yield.

As a result, it is necessary to develop a curved plate forming apparatus capable of improving manufacturing yield and capable of managing the curvature dimension.
