The apparatus and methods are particularly suitable for thermohydroforming parts with complex deep drawn geometries yet which retain relatively smooth outer surfaces and internal material structure. The apparatus and methods provide a fast and efficient means for composite part manufacturing. | 05-12-2016 |
20160136710 | METHOD FOR BENDING THE MACHINE BED OF A STAMPING PRESS, AND STAMPING PRESS - A method for warping the machine bed of a punching press, which machine bed has an aperture for carrying away punching parts and rubbish, compensates at least partially for a bending of the machine bed caused by the punching force during the punching operation. Thereby, forces acting transverse to the punching direction are introduced into the machine bed and/or forces acting transverse to the punching force direction are produced inside the machine bed, by means of which the machine bed warps in the direction towards the press ram and indeed such that it warps stronger in the area adjacent to the aperture than in the areas adjacent to its longitudinal sides. | 05-19-2016 |
20160136711 | PRESS FORMING APPARATUS AND PRESS FORMING METHOD FOR A SEMI-SOLID METAL MATERIAL - Provided is a press forming apparatus for a semi-solid metal material, including: a slide caused to make a reciprocating linear motion; a sub-slide mounted so as to be movable relatively to the slide; a fluid pressure mechanism interposed between the slide and the sub-slide, which is capable of moving the sub-slide relatively to the slide by fluid pressure; an upper die mounted to the sub-slide; and a lower die. The press forming apparatus is configured to press-form the material while applying predetermined pressure to the material for a predetermined period by bringing, along with descent action of the slide, the upper die into contact with the material fed into the lower die, then stopping the slide at a predetermined position, and moving the upper die mounted to the sub-slide relatively to the slide by the fluid pressure mechanism under a state in which the slide is stopped. | 05-19-2016 |
20160158821 | PRESS FORMING METHOD AND METHOD OF MANUFACTURING PRESS-FORMED PART - There is provided a method of manufacturing a curved channel part having a curved portion in a vertical wall portion by press forming, the method restricting stretch flange deformation, which occurs in the vertical wall portion and a flange portion. The method includes a shear deformation step as a step of forming the vertical wall portion. In the shear deformation step, a boundary-side portion of a base section of a blank with respect to a deformation section, and an outer portion of the deformation section are individually restrained, a portion to be a vertical wall portion of the deformation section is shear-deformed in a sheet face, and a material is caused to flow from a portion separated from a curved portion toward the curved portion in an outer edge portion of the portion to be the vertical wall portion. | 06-09-2016 |

20160375483 | Tooling and Method for Drawing and Flanging a Prototype Part - A prototype part drawing/flanging tool is provided that are arranged in a draw die set-up and a flange die set-up. The draw die set-up includes a binder ring, a pad; a flange forming ring, and a punch. The flange die set-up includes the flanging ring, the pad, and the punch. The draw die set draws a blank and the flange die set forms a flange on the blank in two separate operations using the same die parts in the two operations. A method is disclosed for making a formed and flanged part that begins by drawing a blank held by a pad, a flanging ring and a binder ring against a punch in a press to form a drawn blank. The drawn blank is then laser trimmed to form a trimmed/drawn blank. The trimmed/drawn blank is then clamped between the pad and the punch while the flange forming ring forms a flange into a flange forming groove. | 12-29-2016 |
