Description

[0001] A SHEET FORMING DEVICE AND METHOD OF USE OF THE DEVICE

[0002] Technical Field

[0003] The present invention relates to a forming device and method of use of the device which makes it possible to perform forming without changing the thickness of the sheet piece; applies clamping, compression and tension processes to the sheet to be formed in such a way as to be simultaneous and / or gradual; aims to reduce the amount of material scrapped by changing the geometric shape at the beginning of the process and the geometric shape at the end of the process; has no theoretical forming limit; and will contribute to sustainable production.

[0004] Background of the Invention

[0005] Today, sheet forming process is carried out by two different forming methods, wherein the drawing and stretching methods are applied separately. While the drawing method applies forces to the sheet in the compression direction and thickens the sheet, the stretching method applies forces in the tension direction and thins the sheet. These two processes make it possible for the operator to perform forming with manual dexterity. During these processes, changes in sheet thickness, thinning or thickening are observed.

[0006] For this reason, there is a need for a new forming device which, different from the existing methods, enables the sheet thickness to be kept as constant as possible and the geometric shape of the sheet to be changed.

[0007] The United States patent document no. US2023201903, an application included in the state of the art, discloses a press forming tool and press forming method. According to the method, forming using the upper die and the lower pad is carried out in such a way that, during an initial stage of forming, the top portion, the side wall portion and the flange are formed. A portion having a large wall depth at the bottom edge and a portion in a first curved portion of the side wall portion is formed, and a torsional shaped portion is formed in the inclined side portion and is formed by using the upper die and the lower die. It is carried out at a late stage of forming such that the torsional shape portion is formed into a flange portion and a flange portion is formed in the second curved portion and in the recessed side portion so as to achieve the formation of a target shape. The technique makes it possible to apply it to a press forming part in which wrinkles or fractures occur in the flange itself, and to simultaneously suppress the wrinkles and fractures occurring in the flange.

[0040] The upper head (4) and the lower head (5) included in the inventive forming device (1) are used to constitute a support base for the tension and compression jaws (6, 7) used in sheet forming, and for the first connection plate (11) and the second connection plate (12).

[0041] The tension jaws (6) and compression jaws (7) included in the inventive forming device (1) are located on the surfaces of the upper head (4) and the lower head (5). The tension jaw (6) and compression jaw (7) have a trapezoid shape if the upper head (4) and the lower head (5) are in quadrangular form, are at least one in number and are placed mutually and connected to each other by the resistance element (10).
