Shaping apparatus and shaping method for chassis

Abstract

A shaping apparatus of the invention is used for shaping a chassis and includes a machine body, a first die, a second die and a plurality of shaping members. The first die is disposed at a side of the machine body and the chassis is suitable to be placed and positioned at the first die. The second die is disposed at another side of the machine body. The machine body drives the second die to move relatively to the first die so that the second die moves close to or far away from the first die. The shaping members are detachably assembled to at least one of the first die and the second die so that when the first die and the second die approach each other, the shaping members press and deform the chassis thereon. A shaping method for a chassis is also disclosed.
