    摘要: The present disclosure proposes a tool for shear cutting, wherein the tool has a lower blade, a hold-down device and an upper blade, wherein the lower blade has a pressure-loaded surface and a cutting surface, wherein it is possible for a workpiece to be arranged between the hold-down device and the contact surface, wherein the upper blade is movable in relation to the lower blade along a cutting direction predetermined by the cutting surface, wherein a contour profile of the lower blade has a jagged elevation at the transition from the cutting surface to the pressure-loaded surface.

    摘要: An apparatus for improving the accuracy of machines which shear plate materials in general and sheet metals in particular. The apparatus comprises an indicator that is magnetically mounted to the shearing blade and extends downward toward the work table of the machine to give an indication of where the blade will pass through the metal.

    摘要: Provided is a method for bonding metal parts manufactured by splitting longitudinally an end part of a metal plate or a metal rod having a rectangular, polygonal, or elliptical shape, in which the length of incision in the split portion can be freely adjusted and smooth split face can be formed. The metal parts are manufactured by the process comprising the steps of securing a metal plate by pinching both sides thereof with a clamping device, or securing a metal rod by pinching at least two opposite-facing portions on the periphery thereof with a clamping device; splitting longitudinally by slitting or cleaving the metal plate, or the metal rod, by pressing a slitting punch or a cleaving punch against the face of one end of the metal plate, or the metal rod; and advancing the splitting further by repeating the same operation of pressing the same punch stated above against the cleft of the splitting; and is characterized further in that, in each time of the press-splitting operation, the position of the clamping device on at least one side is moved in advance of the next pressing by a stroke corresponding to the distance from one end of the metal plate, or the metal rod, to the distal end of a split-desired portion.

    摘要: A hold-down device for plate shears configured to, be pressed down onto a plate to be cut by a mechanically controlled, non-variable displacement. A hold-down device, which can be altered in terms of the pressing force and consequently permits a longer edge life and shorter displacements, and in turn lower indexing times. The starting position of the hold-down device is set before the beginning of the displacement.
