  • Publication number: 20140013907
    Abstract: Methods for producing slots in tube walls are described and illustrated, along with devices for producing slots in tube walls. In some cases, a first number of punches arranged in a row pierce through the tube wall and in so doing produce slots, followed by another number of punches piercing through the tube wall in such a way that the slots produced by the first number of punches alternate with respect to the slots produced by the second number of punches. Also, in some cases an internal support is used, whereby small slots are first produced in the tube wall while the internal support is within the tube. After the internal support is removed, the slots are widened to finished dimensions. The internal support can include upper and lower parts designed to engage one another in a sawtooth or undulating manner.

  • Patent number: 6681611
    Abstract: A process for manufacturing holes on the circumference of a hollow section situated in an internal high pressure forming tool uses the action of a punch integrated in the forming tool. A desired breaking point is formed on the hollow section, which follows the edge contour of the operating face of the punch; and after the withdrawal of the punch, the hollow section material surrounded by the desired breaking area, acted upon by internal high pressure, is extracted from the hollow section from the inside to the outside, forming a hole. In order to produce holes on the circumference of hollow sections, in which the shape of the outer circumference of the hollow section is maintained, the wall of the hollow section is weakened to form an unstable thin area. The punch penetrates into the wall of the hollow section at an internal high pressure which corresponds to the forming pressure for forming a hollow blank inserted in the forming tool.

  • Patent number: 6155150
    Abstract: An apparatus and method for driving a ramped drive assembly longitudinally, to drive a penetrator transversely, to cause the penetrator to penetrate and withdraw from a downhole tubular element. An anchor holds the tubing punch assembly in place in the downhole tubular element. A double piston assembly drives the drive assembly hydraulically in the downhole direction, thereby driving the ramp downhole, to force the penetrator outwardly to penetrate the tubular element. Thereafter, pulling uphole on the work string shears a shear sleeve, separating the housing of the tubing punch assembly from the work string. Further pulling on the work string partially withdraws the ramped drive assembly from the tubing punch assembly, thereby withdrawing the penetrator into the tubing punch assembly.

  • Patent number: 5527126
    Abstract: A press fit between a spline shaft and a spline hub is disclosed. The spline shaft has, on one end region, a spline-shaft toothing arranged on the outside and the spline hub has an inner spline-hub toothing which corresponds essentially to the spline shaft toothing. In the prefabricated state, the spline hub toothing is provided with an undersize in relation to the spline-shaft toothing. Those edges of the tooth flanks of the spline-shaft toothing at the front on the insertion side are designed as cutting edges which, during the insertion of the spline shaft into the spline hub come into engagement with a chipping effect on the tooth flanks of the spline-hub toothing. So as to avoid a risk emanating from these chips, the depth of insertion of the spline shaft into the spline hub is limited by a shoulder, and the distance between the cutting edge and the shoulder is smaller than the extension of the spline hub. As a result, the chips remain within the spline-hub toothing of the spline hub.

A punch is slideably mounted in a cylindrical die so as to be movable to a position in which a notch in the punch, and the die form an adjustable opening for receiving the sheet metal as the template edge engages the side of the punch. The punch is reciprocated in excess of several cycles per second to progressively nibble crescent shaped sections from the edge of the workpiece until it conforms to the template edge. In a second version, the die has a slot for receiving the edge of the sheet metal as it is being nibbled so that the sheet metal and template do not buckle. Another form of the nibbling machine is employed to shape the end of a tubular workpiece mounted on an elongated anvil.

  • Patent number: 4235160
    Abstract: A percolator having a cylindrical basket concentric with a wand is provided with a filter paper cup having an annular bottom coextensive with the bottom of the basket and having upstanding fluted sides. The filter cups are formed by cutting and forming them into a nest of cups having an imperforate bottom, transferring the nest of cups to a frusto-conical die having a circular top commensurate with the circular bottom of the filter cups, a central die-hole, and outwardly and downwardly flaring sides corresponding to the natural outward flare of the nested cups, and punching an axial hole in said nested cups while on said die by means of a punch complementary with said die-hole.

  • Patent number: 4205569
    Abstract: High speed tube cutting apparatus provides die means for the simultaneous cutting of a plurality of tube segments from a length of tubing. Preferred embodiments are capable of cutting the tube segments in extremely short lengths and with the ends thereof formed on a bias. The improvements of the invention eliminate waste and enable the shearing of the tube segments to be achieved in a single stroke of the included die means. A further feature of the invention apparatus is that it provides means for precisely realigning sheared tube segments with the tubing from which they have been cut to facilitate their ejection under the influence of the advancement of such tubing.

  • Patent number: 4165664
    Abstract: The present invention relates to an apparatus for making cuts along the circumferential surface of a can. The apparatus includes a frame and a plurality of rollers rotatably coupled to the frame for receiving and movably supporting the circumferential surface of the can. A cutter is provided for cutting along the circumferential surface of the can. A guide is coupled to the cutter and to the frame in known registration with the rollers for movably guiding the cutter along the desired cutting path over the circumferential surface of the can.In a first preferred embodiment of the present invention the rollers are arranged so as to allow the can to rotate about its central cylindrical axis. The rollers are elongated and cylindrical in form and each has an axis of rotation generally parallel with the central cylindrical axis of the can.

  • Patent number: 4141124
    Abstract: Disclosed is an improved method and apparatus for removing damaged or worn vanes which are brazed or otherwise metallurgically attached between the concentric inner and outer shroud members of a gas turbine compressor stator. The method involves punching one of the attached vane ends in the radial direction relative to the concentric shroud members with sufficient force to shear the metallurgical joints holding the vane in the shroud slots. During punching, the shroud members are rigidly supported against deformation in the vicinity of the attached vane ends and the vane itself is supported laterally to prevent buckling thereof. With the invention, a stator can be repaired with no diminution in structural strength as compared to a new part. A punch and die assembly for use in removing a damaged vane is also disclosed.

  • Patent number: 4059036
    Abstract: An internal member for supporting a hollow body during shearing in the form of a close-fitting solid body. The body comprises at least portions meeting in the shearing plane and each portion including at least one split ring having a single gap in its periphery to allow it to expand to fit the hollow body. Expansion may be effected by axial movement of frusto-conical plugs corresponding to and co-operating with frusto-conical inner surface in the rings. Each ring may either comprise a single component, preferably notched on its inner face to increase flexibility, or be in the form of a thin split cylindrical shell surrounding a plurality of inner segments.

  • Patent number: 3955453
    Abstract: In tube-shearing apparatus of the kind employing relatively transversely moving apertured dies and an internal supporting mandrel, the mandrel comprises an elastomeric body which is compressed axially with the high force to expand it radially against the tube wall such as to form not merely an internal support but effectively a supporting shear blade inside the tube. This allows clean shearing also of tubes having internal protuberances such as welding seams.
