    摘要： Horizontal fuel element bundle shears have a stepped blade and a horizontalagazine for accommodating an undismantled uclear reactor fuel element which is to be cut up. In the fuel element bundle shears, the nuclear reactor fuel element, for the cutting operation to be performed, is pushed with a stepwise movement through a magazine opening in front of which the stepped blade is displaceable in a direction perpendicular to the longitudinal axis of the fuel element. Each portion of the stepped blade has a cutting edge. In order to achieve a lower rate of wear of the stepped blade while at the same time obtaining a good cut and a low cutting force, the stepped blade has two cutting edges which are separated from each other by a step, thereby forming two blade portions which are in superposed relationship with each other. The lower blade portion is set back with its cutting edge relative to the cutting edge of the upper blade portion by a step distance which corresponds at least to the width of the precompacted fuel element bundle. The upper cutting edge is higher or longer than the lower cutting edge. Because of this configuration, the two blade portions, which are separated by a step, do not come into engagement with the bundle simultaneously but instead engage the bundle sequentially.

    摘要翻译： 水平燃料元件束剪具有阶梯式叶片和用于容纳要被切割的未拆卸的核反应堆燃料元件的水平仓。 在燃料元件捆束剪切机中，用于要进行的切割操作的核反应堆燃料元件被逐步地移动通过料仓开口被推动，其中阶梯式叶片可以在垂直于 燃料元件 阶梯式刀片的每一部分都具有切削刃。 为了实现台阶刀片的较低磨损率，同时获得良好的切削和低切削力，台阶刀片具有两个彼此分离的切削刃，从而形成两个刀片部分 它们彼此重叠关系。 下叶片部分相对于上叶片部分的切割边缘具有相对于预压缩燃料元件束的宽度的台阶距离的切割边缘。 上切割刃高于或低于下切割刃。 由于这种构造，通过台阶分开的两个叶片部分不会同时与束接合，而是依次接合束。

    摘要： An arrangement for diagonally cutting up the end of a rectangular tube is provided. In order to be able to utilize the shearing principle with such diagonal cuts, the clamping jaws are arranged as stationary shearing blades having shearing edges that define a cutting plane. The rectangular tube being cut to size is diagonally inserted between the clamping jaws so that a pocket which is to be cut off stands out beyond the cutting plane. A shearing knife moves along the pocket and has an arrow-like shearing edge which inserts into this pocket-shaped projecting end and cuts off the end from the inside against the stationary cutting blade. Each of the three stationary cutting edges is brushed off by the movable cutting edge by at least one movable component.

    摘要： A radius corner forming apparatus and method and which utilizes a plate to receive a metal sheet in which a corner portion is to be removed to form a radius corner. A die block and punch set is removably attachable to a conventional punch press in order to sever the corner portion of the sheet to produce the radius corner thereon. The plate which receives the metal sheet is resiliently mounted to oppose the pressure of the punch when shifted. A plurality of differently sized radius corner die blocks and co-operating punches are provided.

    摘要： A coil slitting tool in the form of a rotary serrator knife for use on coil slitting machines comprises a plurality of serration undulations disposed on one or more faces about the outer periphery. The rotary serrator knife tool may comprise a concentrically located bore about an inner diameter for mounting on an arbor and may further incorporate a keyway. The rotary serrator knife may be formed from an assembly comprising, a central rotary disk about which mount one or more removable inserts comprising the serration undulation portion. The one or more removable inserts may comprise serration undulations on one side or two sides and mount substantially to the perimeter of a mounting disk by use of fasteners.
