  • Patent number: 6832536
    Abstract: A tube cutting machine comprises a tube secured in a chuck tightened against an outer tube wall and by a mandrel expanded within the tube against the tube inner wall opposite the chuck. A blade with a conical body side on the tube body side advances into the tube at the body side angle, eliminating longitudinal force against the tube body and accumulation of tube material on the blade body side. In alternative embodiments, either the tube or the blade can rotate. As the blade edge enters the tube wall, the blade end side, opposite the body side is also conical and pushes the tube cut portion longitudinally away from the tube body, causing the tube before the blade to neck under the longitudinal force imposed by the blade end side. The blade is reversed when the neck weakens and is unable support the tube cut portion but has not yet broken, referred to as the failure point. The blade is then withdrawn and the neck is snapped off. The failure point is detected by a rod urged transversely against the tube end.

  • Patent number: 5699708
    Abstract: The invention provides a punch press capable of impressing a plurality of holes or other changes in a workpiece. The central core piece of the punch press receives the workpiece and expands until it touches the inner walls of the workpiece. This holds the workpiece in place and prevents any workpiece movement or distortions in the holes formed because of movement of the workpiece. Hydraulic cylinders impel the plurality of punches toward the workpiece at substantially the same pressure and time.

  • Patent number: 5248366
    Abstract: Flexible tubular film is helically cut into a flat strip by feeding the tubular film in flattened form from a supply source to a film feeding means advancing the flat film tube at a predetermined velocity to a tube expansion zone in which the flat tube is expanded into a generally cylindrical tube and passed axially over a hollow mandrel slightly less in external diameter than the diameter of the expanded tube to be cut helically while on the mandrel into a flat strop that is removed at an angle to the mandrel axis. The tube is expanded in the zone by inflation with air fed through the mandrel in a direction countercurrent to the direction of tube movement and under a pressure sufficient to render the expanded tube stiff as it slides over the mandrel and resistant to deformation while being helically cut.

  • Patent number: 4799412
    Abstract: Method for severing the ends of tubing by feeding the end of a tube through a die such that its end to be sheared extends beyond the die while presenting a shear blade with a pointed end in the interior of the tube end. After the shear blade is inserted into the tube, relative vertical movement between the shear blade and the tube is effected to cause the pointed end to initially puncture the tube wall adjacent the die. The shearing blade is thereafter shifted laterally and vertically to shear remaining portions of the tube wall.

  • Patent number: 4783982
    Abstract: A system for trimming a can body wherein a can body is positioned within a cutting member so that the cutting member is at the location where the can body is to be trimmed. A resilient, deformable object is inserted into the can body and positioned therein so that at least a portion thereof is located radially opposite portions of the can body on each side of the cutting member. The resilient, deformable object is deformed so as to move a first part thereof against a portion of the can body to prevent longitudinal movement of the can body and then to move a second part thereof against the portion of the can body located between the cutting member and the open end of the can body in a radially outward direction so as to sever that portion from the can body.

  • Patent number: 4693404
    Abstract: A tool has a hollow elongated body 10 made up of a leading section 12 attachable to a tow-cable by a clevis 28, an intermediate section 14 and a trailing section 20 housing a hydraulic cylinder 24 and attachable to a main liner 30. The intermediate section includes a frusto-conical wall in two parts 16 and 18, each of 180.degree. angular extent. The ram 24 operates a wedge 22 longitudinally to move the first part 16 outwardly or inwardly transversely of the body. The parts 16, 18 are slidably trapped to the wedge by slide components projecting into grooves. The tool is pulled by the two cable into the main with the part 16 retracted. Then the part 16 is moved outwardly to burst and enlarge the main, allowing the tool to advance further after retraction of the part 16. The parts 16, 18 each have an external longitudinal rib 68, 70. The part 16 has longitudinal marginal extensions overlapping the longitudinal margins of the part 18.

  • Patent number: 4151773
    Abstract: This disclosure describes a device for repeatably scribing a V-shaped scratch having sharply defined dimensions on the interior surface of a nuclear reactor fuel rod tube. A cutting tool having a V-shaped cutting tip is supported within the fuel rod tube so that the V-shaped cutting tip can be pivoted about an axis and scribe a scratch on the interior surface of the fuel rod tube. Lengthwise the scratch runs parallel to a line drawn through the axis of the fuel rod tube and is in the shape of an arc, and widthwise the scratch is V-shaped. This shape is used because the dimensions of the scratch can be plugged into appropriate formulas to calculate stress intensity of cracks in fuel rod tubes. Since the fuel rod tubes which are to be scribed may be radioactive, the scratching assembly is designed for use in a fixture which allows it to be operated in a cave by remote control handling devices.

  • Patent number: 4131979
    Abstract: Automated machine for the continuous bias cutting of an elongated tube of material, such as tubular knitted fabric, into a plurality of individual strips, and winding the strips into a plurality of rolls. The tubular material is advanced axially at a uniform rate from a supply to a cutting and rolling section by a plurality of skewable rotatable cylinders acting as a positive feeding means. As the tubular material is withdrawn from the supply, it passes over a spreader which opens and tensions it. The skewed cylinders cause the tube to rotate about its axis as it advances. Control means are utilized to adjust automatically the skew angles of the cylinders, to increase or decrease the rate of advance of the tube, to compensate for variations inherent in the material which affect its rate of feed. Control means also are utilized to adjust automatically the tension exerted by the spreader, to correlate such tension with the rate of advance as determined by the skew angles of the cylinders.
