The shaping clamp with the inflatable device can reduce the error of the shaped piece 200 to be shaped and improve the quality and appearance effect of the product.

It should be noted that the shape of the inner surface of the shaping chamber 130 needs to be the same as the final shape of the to-be-shaped member 200 to be obtained, specifically, the to-be-shaped member 200 may be a flat or curved sheet or plate in the initial state, before shaping, the to-be-shaped member 200 needs to be bent by a certain angle so that the to-be-shaped member 200 can enter the shaping chamber 130, and then the to-be-shaped member 200 is pushed against the shaping chamber 130 by the expansion of the expansion film 310. Wherein, the inner surface of the member to be shaped 200 refers to the surface of the member to be shaped 200 near the center of the shaping chamber 130, and the outer surface of the member to be shaped 200 refers to the surface of the member to be shaped 200 near the inner wall of the shaping chamber 130.
