    摘要： A manufacturing method and a press apparatus improve the productivity of the manufacture of a press-formed object from a sheet blank, such as a nozzle hole plate of a fuel injector. The nozzle hole plate of a fuel injector has a plurality of holes differing, for example, in size and punch direction with respect to the sheet blank. In the case of the manufacture of a nozzle hole plate, a first amount of nozzle holes of equal punch angle and size are formed continuously by a die unit in a bandlike sheet blank workpiece while the workpiece is fed through the die unit one way in its length wise direction. Then, the feed direction is reversed, and the die unit is rotated and a further amount of nozzle holes are formed continuously by the same die unit. As a result, the number of die unit positioning operations involved in forming a quantity of nozzle hole plates is equal only to the number of different nozzle holes formed in each nozzle hole plate. The greater the number of nozzle hole plates manufactured from a single roll of bandlike sheet, the more manufacturing labor is saved, and the greater productivity is improved.

    摘要翻译： 制造方法和冲压装置提高了来自诸如燃料喷射器的喷嘴孔板的片状坯料的压制成形物体的制造的生产率。 燃料喷射器的喷嘴孔板具有例如相对于板坯的尺寸和冲头方向不同的多个孔。 在制造喷嘴孔板的情况下，通过模具单元在带状板坯工件中连续形成具有相同冲头角度和尺寸的第一量的喷嘴孔，同时工件在其中以单向方式供给到模具单元 长度方向。 然后，进给方向相反，并且模具单元旋转，并且通过相同的模具单元连续地形成更多量的喷嘴孔。 结果，形成一定数量的喷嘴孔板所涉及的模具单元定位操作的数量仅等于在每个喷嘴孔板中形成的不同喷嘴孔的数量。 由单条带状片材制造的喷嘴孔板数量越多，节省制造劳动力越多，生产效率提高。

    摘要： A gear grinding machine and a gear grinding method, in which a gear-shaped grinding stone is caused to engage a gear-like workpiece and one of the gear-shaped grinding stone and the gear-like workpiece is reciprocated relatively to the other in axial direction thereby to grind the tooth flanks of the workpiece, are disclosed. The rotational resistance is applied by a brake unit to the rotationally driven side. The grinding resistance and the rotational resistance interfering with the relative reciprocal motion are detected by torque sensors and input to a control unit, the average value of each of the signals is compared with a reference value by an arithmetic unit and, in the case where there is a difference between the average value and the reference value, the rotational resistance is changed by activating the brake unit. Thus, a high machining accuracy can be maintained even when the sharpness of the grinding stone is reduced.
