    • The integrated bicycle chain ring assembly (100) has smaller chain ring (102) and larger chain ring (104). The chain rings are integrally formed to engage a bicycle chain. Multiple connection structures (106) which are integrally formed perform a connection between the chain rings. Several mounting apertures (110) receive mounting hardware for connecting the chain rings to a bicycle crank-arm. The mounting apertures are formed in a peripheral portion of one of the chain rings. The method of manufacturing bicycle chain ring assembly is also included. The desired degree of stiffness is achieved reliably by the connection structures. The weight of chain ring assembly is reduced effectively.

    • The method for manufacturing a plastic worked article includes the steps of shaping an article for plastic working by a semisolid molding in which molten metal including both a solid phase and a liquid phase is introduced into a die; performing a pre-plastic working heat treatment on the article for plastic working for causing blisters by expanding gas cavities included in the article for plastic working; and forming a plastic worked article by plastic working the article for plastic working after the pre-plastic working heat treatment. The plastic working of the article for plastic working is performed in such a manner that a tensile stress applied direction at a tensile stress applied portion to which tensile stress is principally applied in actual use of the plastic worked article substantially accords with a plastic flow direction at a portion of the article for plastic working corresponding to the tensile stress applied portion.

    • This invention is characterized in that, during the manufacture of an integrally-forged light alloy wheel for an automobile, an outer rim (12), which rises from the outer circumference of a disc surface (11), is formed simultaneously with the pattern of the disc surface (11) by die forging. While the die forging is carried out, an upper die (41) is changed in turn as a mounting base is moved along guide rails provided at an upper portion of a press. In order to form a flange (3) on an inner rim of a wheel having a pattern on its disc surface (11), by a spinning method after the outer rim has been formed, a pair of mandrels for clamping the disc surface (11) therebetween are used, a part or the whole of the clamping end surface of at least one of these mandrels having a shape corresponding to the pattern on the disc surface (11). When it is difficult to extend the inner flange (3) upward along a raising portion of a mandrel, the flange (3) is rolled to a certain extent, and the end portion of this flange (3) is then expanded by a press. The resultant flange (3) is pressed against the mandrel again by a roller to form an inner rim. An unnecessary thin-walled portion (15), which is formed on the disc surface (11) by the die forging, is opened by plasma cutting.
    • 本发明的特征在于,在制造用于汽车的整体锻造的轻合金车轮的过程中,从盘表面(11)的外圆周上升的外缘(12)同时形成 盘表面(11)通过模锻。 在执行模锻时,随着安装基座沿设置在印刷机上部的导轨移动,上模41依次变化。 为了在其表面(11)上具有图案的轮的内轮缘上形成凸缘(3),在形成外缘之后通过旋转方法形成用于夹紧盘表面(11)的一对心轴 ),所述这些心轴中的至少一个的夹紧端表面的一部分或全部具有对应于盘表面(11)上的图案的形状。 当难以将内凸缘(3)沿着心轴的上升部向上延伸时,凸缘(3)被轧制到一定程度,然后通过压力将该凸缘(3)的端部扩大。 所得到的凸缘(3)通过辊再次压靠在心轴上以形成内缘。 通过模锻而在盘表面(11)上形成的不必要的薄壁部分(15)通过等离子体切割而被打开。
