    • Apparatus for mounting a pair of die members so that one die member can move toward and away from the other die member. The apparatus includes a pair of spaced die shoes for mounting respective die members and an electromagnetic unit for moving one of the die shoes toward the other die shoe. The electromagnetic unit includes a coil mounted on one of the die shoes and an armature mounted on the other die shoe, the electromagnet and the armature being between the die shoes. The armature is aligned with and partially extends into a recess in the central portion of the coil so that, when current flows through the coil, the armature is attracted to the coil and moves the other die shoe toward the one die shoe. A bias structure biases the other die shoe away from the one die shoe. Such bias structure can take the form of an air cylinder or a spring.
    • 用于安装一对模具构件的装置,使得一个模具构件能够朝向和远离另一个模具构件移动。 该装置包括一对分开的模具,用于安装相应的模具构件和用于将模具中的一个移动到另一模具的电磁单元。 电磁单元包括安装在模具之一上的线圈和安装在另一个模具靴上的电枢,电磁体和电枢位于模具之间。 电枢与线圈的中心部分对准并部分地延伸到凹部中,使得当电流流过线圈时,电枢被吸引到线圈并使另一个模具靴朝向一个模具靴移动。 偏置结构使另一个模具鞋离开一个模具鞋。 这种偏置结构可以采用气缸或弹簧的形式。

    • An apparatus for utilizing electromagnetic energy for producing high impact forces by means of a ram propelled against a work piece. The work center of the apparatus includes a ram assembly of bolted construction having a hollow ram shaft, which ram assembly includes a gap between opposing conductive surfaces including associated fastener screws of driving disc and ram shaft of at least about five-sixteenths of an inch. A solid mass recoil assembly provides integral housing and recoil mass, enabling aerostatic bearing functioning, and also lowers shock and vibration levels to operator and equipment.
    • 一种利用电磁能量产生高冲击力的装置,该冲击力是通过推进在工件上的压头产生的。 该设备的工作中心包括具有中空的柱塞轴的螺栓结构的柱塞组件,所述柱塞组件包括相对的导电表面之间的间隙,所述间隙包括至少约五分之一十六分之一英寸的驱动盘和柱塞轴的相关紧固螺钉。 固体质量反冲组件提供一体式外壳和反冲质量,使空气静力轴承功能起作用,并降低操作员和设备的冲击和振动水平。
