    • A double action die set for closed forging to be equipped in a reciprocating press consisting of a stationary base and a slide. Each die is equipped with one set of a metal mold and a punch. A stationary side die is fixedly secured to the stationary base, while a movable side die is fixedly secured to the slide. Each one of the stationary side die and the movable side die comprises therein a metal mold supporting outer piston of hollow shape, a punch supporting inner piston slidably engaged with a hollow space in the outer piston, and a common oil chamber for supporting the outer piston and the inner piston with a same hydraulic pressure.According to this invention such advantages as to reduce the height of the die set and to move the pressurized oil only within the same oil chambers can be obtained.
    • 一种用于封闭锻造的双作用模具组装在由固定基座和滑块组成的往复式压力机中。 每个模具都配有一套金属模具和冲头。 固定侧模具固定地固定到固定基座,而可移动侧模具固定地固定到滑块。 固定侧模具和可动侧模具中的每一个包括支撑中空形状的外活塞的金属模具,与外活塞中的中空空间可滑动地接合的冲头支撑内活塞,以及用于支撑外活塞的公共油室 和具有相同液压压力的内活塞。 根据本发明,可以获得这样的优点,即减小模具的高度并且仅在相同的油室内移动加压油。

    • A method of roll forming hollow parts comprises introducing a workpiece into the space between a plurality of rolls rotatably arranged in spaced and parallel relationship, in parallel with the axes of the rolls, imparting rotation to the workpiece from drives through either the rolls or flanges disposed at both ends of the workpiece, at the same time forcing mandrels, slidably fitted at ends in the central openings of the flanges, through the openings into the workpiece, longitudinally from the both ends thereof, toward each other, and removing the excess metal left in the midportion of the workpiece between the mandrels by slightly moving the rolls toward each other for added compression, thereby producing spaces between the mandrels and the workpiece, and by moving the mandrels axially together with the excess metal to separate the latter from the rest of the workpiece.
    • 一种辊成型中空部件的方法包括将工件引入到与辊的轴线平行的可旋转地布置成间隔和平行关系的多个辊之间的空间中,通过辊或凸缘设置的驱动通过工件赋予工件 在工件的两端处,同时迫使心轴,可滑动地装配在凸缘的中心开口中的端部,通过开口从工件的两端纵向彼此朝向彼此,并且去除多余的金属 通过将辊轻轻移动到彼此以增加压缩,从而在心轴和工件之间产生空间,并且通过与多余金属轴向移动心轴,将心轴与其余部分分离,从而在心轴之间的中间部分 工件。
