Description

[0001] Superplastic forming device [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a super plastic forming apparatus, and more particularly, to a super plastic forming apparatus capable of injecting a molded material provided in a metal mold by injecting gas.

Generally, various mechanical parts are formed by casting and press molding. The double press is provided with molds of the product shape at the upper and lower parts, and the upper mold is placed at a constant pressure in the state where the molding to be molded is placed on the upper part of the lower mold. So that the molded product is molded and formed into an appropriate shape on the upper and lower molds.

However, parts and the like formed by such a press type are mainly formed by using a metal having a low elongation. This is because when a metal plate having a high elongation (200% or more) and a thin plate of aluminum or titanium The metal itself is torn and can not be formed. This makes it unsuitable for manufacturing parts used in fields requiring light weight, for example, in the aerospace industry, the automobile industry, and the electronics industry, and has a problem that noise and vibration are relatively generated.

In order to solve these problems, super plastic molding has recently been emerging. Superplastic forming is a technique in which a material of a fine grain structure is pressed into a plate placed on a mold in a sealed container by applying pressure to a gas on the opposite side of the mold using a characteristic that the material has a high ductility at a high temperature and a low stress of several hundreds to several thousands% . However, in order to mold the plate, the super plasticizer requires a considerable time to raise the temperature of the metal mold to a high temperature at which the metal mold can be easily deformed. Therefore, it takes a considerable amount of time to manufacture a single molded product There is a problem.
