Patent number: 8429946Abstract: A press-working apparatus capable of forming a clear character line. The press-working apparatus forms a product having a character line. The press-working apparatus comprises an upper die and a lower die arranged across a steel sheet, an upper die mechanism for moving the upper die toward and away from the lower die, a first holder and a second holder for clamping the steel sheet and applying an unwrinkling force to the same, and a control unit for controlling the upper die mechanism and the first holder. The upper die is divided on the character line of the product into a first upper die and a second upper die. The control unit makes the unwrinkling force by the first holder stronger than that by the second holder, so that the steel sheet is press-worked by the second upper die and then by the first upper die.Type: GrantFiled: October 15, 2007Date of Patent: April 30, 2013Assignee: Honda Motor Co., Ltd.Inventors: Shingo Maeda, Hideo Meguri, Seiji Takahashi, Yuichi Nagai

Patent number: 8296110Abstract: A forming speed determination method for determining a forming speed of a press-processing device with a plurality of measurement points on a sheet material to conduct press-forming of the sheet material with a press-processing device at a predetermined forming speed. Strain states at respective points on the press-formed sheet material are plotted on a forming limit diagram including the forming limit curve of a sheet material to produce a strain distribution chart. Subsequently, the closest point to the forming limit curve among the points is defined as a specific measurement point. When this specific measurement point is located in the bulge region, the forming speed of a press-processing device is decreased to be slower than the above-mentioned predetermined forming speed. Meanwhile, when this specific measurement point is located in the draw region, the forming speed of a press-processing device is increased to be faster than the above-mentioned predetermined forming speed.Type: GrantFiled: October 4, 2007Date of Patent: October 23, 2012Assignee: Honda Motor Co., Ltd.Inventors: Yuichi Nagai, Hideo Meguri

Patent number: 7963141Abstract: In a press working apparatus, while a servo motor is acting, an upper die is made to come close to a lower die and press working of the first time is conducted on a steel plate. A slider is raised to a movable punch preparation position. A movable punch is protruded from a die face of the upper die by width and locked by a mechanical lock. The upper die is made to come close to the lower die again and the steel plate is pushed with the upper die and at the same time an additional worked portion is pushed and deformed with the movable punch so as to conduct press working of the second time. After the movable punch has been retracted, the slider is raised.Type: GrantFiled: July 9, 2010Date of Patent: June 21, 2011Assignee: Honda Motor Co., Ltd.Inventors: Yuichi Nagai, Hideo Meguri, Kenzo Takeda, Takayuki Egawa
