Abstract
A material forming apparatus comprises: a support which is positioned at a side of a forming tool with respect to a material arranged on the forming tool to have a first part covered by the forming tool and a second part separated from the forming tool, and which supports the forming tool; a diaphragm which presses the second part of the material while the outer surface of the expanded diaphragm comes in close contact therewith, in a state in which the first part of the material is compressed by the forming tool and the outer surface of the diaphragm; and a volume-varying member which is disposed near the forming tool between the diaphragm and the support so that at least a portion thereof is positioned on the second part of the material.
Claims20
A material forming apparatus which forms an article by transforming a sheet-shaped material to conform the surface of a forming tool, the material forming apparatus comprising:
- a support which is positioned at a side of the forming tool based on a material arranged on the forming tool to have a first part covered by the forming tool and second parts deviating from the forming tool, and which supports the forming tool;
- a diaphragm which has the outer surface on which the material is located and the inner surface on which fluid pressure for expansion is provided, wherein the outer surface of the expanding diaphragm presses the second parts of the material while getting in contact with the second parts in a state where the first part of the material is compressed by the forming tool and the outer surface of the diaphragm;
- and
- a volume-variable member which is disposed near the forming tool between the diaphragm and the support so that at least a portion thereof is positioned on the second part of the material, wherein the second part of the material is compressed on the surface of the volume-variable member by the expanding diaphragm, and which suppresses wrinkling of the material and allows the second part of the material to approach the forming tool according to the continuous expansion of the diaphragm in a state in which the second part of the material is compressed onto the surface of the volume-variable member by the diaphragm and the second part is compressed by the diaphragm and the volume-variable member,
- wherein a structure capable of selectively opening and shielding on a lateral direction between the support and the diaphragm is provided such that an operator can insert the hand or a tool in order to adjust the position of the volume-variable member.

A material forming apparatus which forms an article by transforming a sheet-shaped material to conform the surface of a forming tool, the material forming apparatus comprising:
- a support which is positioned at a side of the forming tool based on a material arranged on the forming tool to have a first part covered by the forming tool and second parts deviating from the forming tool, and which supports the forming tool;
- a diaphragm which has the outer surface on which the material is located and the inner surface on which fluid pressure for expansion is provided, wherein the outer surface of the expanding diaphragm presses the second parts of the material while getting in contact with the second parts in a state where the first part of the material is compressed by the forming tool and the outer surface of the diaphragm;
- and
- a heating unit disposed near to the material to transfer heat to the material,
- wherein the heating unit is located between the outer surface of the diaphragm and the first part of the material, and is transformable by expansion of the diaphragm.
A material forming method for forming an article by transforming a sheet-shaped material to conform the surface of a forming tool, the material forming method comprising:
- arranging the material and the forming tool on the outer surface of the diaphragm so that the material has a first part covered by the forming tool and second parts deviating from the forming tool;
- locating a volume-variable member near the forming tool between the diaphragm and a support, which faces the outer surface of the diaphragm and supports the forming tool;
- expanding the diaphragm by fluid pressure applied to the inner surface of the diaphragm and compressing the second part of the material on the surface of the volume-variable member when the outer surface of the expanding diaphragm presses the second part of the material in a state where the first part of the material is compressed by the forming tool and the outer surface of the diaphragm;
- and
- decreasing the volume of the volume-variable member according to the continuous expansion of the diaphragm in a state in which the second part of the material is compressed onto the surface of the volume-variable member by the diaphragm and the second part is compressed by the diaphragm and the volume-variable member, so as to suppress wrinkling of the material and transform the second part of the material,
- wherein a structure capable of selectively opening and shielding on a lateral direction between the support and the diaphragm is provided such that an operator can insert the hand or a tool in order to adjust the position of the volume-variable member.
