STRUCTURAL MATERIAL STRETCH FORMING JIG, STRUCTURAL MATERIAL STRETCH FORMING SYSTEM AND STRETCH FORMATION OF STRUCTURAL MATERIAL

摘要

PROBLEM TO BE SOLVED: To stretch and form a structural material into various shapes with one forming jig by individually displacing a slide shaft a prescribed quantity each to compose a virtual forming surface and displacing the slide shaft with the only action of a driving means.;SOLUTION: Plural supporting blocks 11 are arranged in the longitudinal direction of a structural material and abutted on the structural material. Plural slide shafts 12 are arranged corresponding to the supporting block 11 individually, and the supporting block 11 is connected to the tip end side. A driving means 13 is arranged corresponding to the slide shaft 12 individually, and the slide shaft 12 is displaced. The slide shaft 12 is supported with a base part 14 so as to displace, and the driving means 13 is fixed. Thereupon, a virtual forming surface is composed by individually displacing the slide shaft 12 a prescribed quantity each. And the slide shaft 12 is composed to be displaced by the only action of the driving means 13. The slide shaft 12 is composed to project by a required length from the base part 14 so that it is displaceable in the vertical direction.;COPYRIGHT: (C)2000,JPO
