    • PROBLEM TO BE SOLVED: To provide a precision forging method of magnesium alloy, which causes work softening in a material by generating dynamic recrystallization in a magnesium alloy material during forging and secures excellent shape accuracy even in a forged product having a complicated shape by adequately arranging an air vent mechanism.
      SOLUTION: A punch 6 is structured so as to be divided into a shaping part 7, a spacer 8, and a punch holder 9 in a direction orthogonal to a pressurization direction. An opening 13 for forming a deformation part 12 is penetratingly arranged at the shaping part 7, and an air vent groove 21 allowing air to be vented in an outer circumferential direction is formed at a surface which is the opposite side of the shaping part of the spacer. A communication groove 24, which enables a part allowing air at the shaping part side of the predetermined spacer not to be vented to communicate with the air vent groove of the spacer, is formed corresponding to a position of an unfilled part 22 for the material flowing in the opening part. When the material made flowable by the work softening due to the dynamic recrystallization of the magnesium alloy stored in a die is filled into the opening by the pressurization of the die, air in the unfilled part is made to be vented outward through the communication groove and the air vent groove.

    • B21J5/00B21J5/06
    • PROBLEM TO BE SOLVED: To provide a forging method capable of carrying out forging which does not generate crack or breakage even at a low temperature by maintaining or increasing hydrostatic-pressure stress without executing conventional strong strain forming performed as a pretreatment of forging of magnesium alloy and without changing an aspect of shearing deformation caused by plastic deformation during forging.
      SOLUTION: Before plastic deformation, magnesium alloy material M in a dent portion 4 for shaping a product is made in a restrained state at an area other than the openings 6 of the dent portion 4 for shaping the product which forms deformed parts 5, so that it is placed under an environment where the hydrostatic-pressure stress in the workpiece is apt to increase simultaneously with the start of pressurization. The openings 6 of the dent portion 4 for shaping the product have a shape which does not have a folding part, so that the aspect of the shearing deformation caused by the plastic deformation is not changed during shaping and friction restriction of material flow during forging is promoted. By this way, the hydrostatic-pressure stress in the magnesium alloy material M is increased.

    • 要解决的问题:提供一种能够进行即使在低温也不产生裂纹或断裂的锻造的锻造方法,通过维持或提高静水压力应力,而不进行作为锻造预处理的常规强应变形成 的镁合金,并且不改变锻造期间由塑性变形引起的剪切变形的方面。 解决方案:在塑性变形之前,用于成型产品的凹陷部分4中的镁合金材料M在凹陷部分4的开口6之外的区域处于受限状态,以形成形成变形部分5的产品 ,使其处于与加压开始同时在工件中的静水压力应力容易增加的环境。 用于成型产品的凹口部分4的开口6具有不具有折叠部分的形状,使得塑性变形引起的剪切变形的方面在成形期间不改变,并且在锻造期间材料流动的摩擦限制为 推广。 通过这种方式,镁合金材料M中的静水压力应力增加。 版权所有(C)2010,JPO&INPIT

    • In a shift lever device, a width dimension of left ribs and right ribs is set larger than a diameter dimension of a left support shaft portion and a right support shaft portion. In the event of an impact load being imparted to a shift lever in different directions to a control lever axial direction, the left rib and the right rib are broken in this impact load direction since the left rib and the right rib are formed so as to face the whole diameter of the left support shaft portion and the right support shaft portion. Impact load can accordingly be absorbed even in the event that an impact load is imparted to the shift lever in different directions to a control lever axial direction. Namely, impact load can be absorbed for impact load directions within a range of a specific angle. Dependency on the impact load direction is accordingly suppressed when absorbing an impact load imparted to the shift lever.
    • 在变速杆装置中,左肋和右肋的宽度尺寸设定为大于左支撑轴部和右支承轴部的直径尺寸。 在向控制杆轴向方向向变速杆施加不同方向的冲击载荷的情况下,左肋和右肋在冲击载荷方向上断裂,因为左肋和右肋形成为 面对左支撑轴部分和右支撑轴部分的整个直径。 因此即使在与控制杆轴向不同的方向上向变速杆施加冲击载荷的情况下也能够吸收冲击负荷。 也就是说,能够在特定角度范围内的冲击负荷方向上吸收冲击负荷。 因此,当吸收施加到变速杆的冲击载荷时,相应地抑制冲击载荷方向。
