    • A down hole pipe cutter (10) is provided to cut a section of pipe from the pipe’s interior. The device includes a lower guide plate (12), an upper guide plate (14), a connector rod (16) interconnecting the lower guide plate to the upper guide plate, and an eccentrically mounted blade drive assembly. The eccentrically mounted blade drive assembly (18) includes an outer tube (20) and an inner drive shaft (22) that are moveably interconnected to both the lower guide plate (12) and the upper guide plate (14). The inner drive shaft has a distal end extending through the lower guide plate (12) with a blade (24) attached thereto. The proximal end of the drive shaft extends above the upper guide plate (14) for attachment to a power source, such as a hand drill. The blade drive assembly (18) is rotatable between a first retracted position and a second extended cutting position.
    • 提供一个井下管道切割器(10),用于从管道的内部切割一段管道。 该装置包括下引导板(12),上引导板(14),将下引导板与上引导板互连的连接杆(16)和偏心安装的叶片驱动组件。 偏心安装的叶片驱动组件(18)包括可移动地互连到下引导板(12)和上引导板(14)的外管(20)和内驱动轴(22)。 内驱动轴具有通过下引导板(12)延伸的远端,叶片(24)附接到其上。 驱动轴的近端在上引导板(14)的上方延伸,用于附接到诸如手钻的动力源。 叶片驱动组件(18)可在第一缩回位置和第二延伸切割位置之间旋转。

    • The invention pertains to a special process and devices for the production preferably by machining of workpieces with non-circular outer and inner contours such as squares, hexagons, ellipses, polygons and the like, or eccentric circular bores and/or tappets. In the claimed process, the workpiece is rotated at constant angular velocity while a tool (e.g. the blade of a lathe tool) set eccentrically in relation to the workpiece is moved without rotating about its own axis at controllable speed in a circular path, workpiece and tool being moved towards one another in cycles with the appropriate advance. This ensures that apart from a small cuttings volume for each advance, very narrow tolerances can be set. The associated device, which has a special gear and optionally an integrated cross slide unit, gimbal-mounted yaw head or eccentric spindle, can be used as a compact tool unit for rotary and milling machines and the like.
