Title:
材料クランプ方法および該方法に用いられる材料クランプ装置
Document Type and Number:
Japanese Patent JP4470190
Kind Code:
B2
Abstract:
A material clamping unit and a method for clamping material, wherein a product having no creases can be manufactured, even if the material has a complex shape, and the method can improve a yield of the product, and can reduce the cost of the dies. The method of clamping materials is for a forming machine that will form thermoplastic sheet material by an upper and a lower die, which sheet material is heated in advance to a predetermined temperature in heating furnace, and thus softened, comprising the steps of: holding both edges of the sides in the running direction of the thermoplastic sheet material, and then transferring the material between the upper die and the lower die of the forming machine: holding the rear and front edges of the sides of the thermoplastic sheet material, which sides are perpendicular to the running direction of the thermoplastic sheet material; and lowering the edges of the sides in the running direction of the thermoplastic sheet material and the rear and front edges of the sides of the thermoplastic sheet material, which sides are perpendicular to the running direction of the thermoplastic sheet material, so that the sheet material will fit in the upper die.
