  • Patent number: 7237423
    Abstract: A blank is stretch formed into a formed piece by bending the blank over a stationary punch. A draw ring has a step that cooperates with a pad ledge to create a step-ledge. The blank is bent with a reverse bend at the step-ledge. Subsequently, the step-ledge travels a short distance relative to the punch to stretch the blank material. Step-ledge travel is achieved by pre-charged cylinders that travel slightly in response to a force exerted on the draw ring and step-ledge by the press ram after the blank is bent into the reverse bend. The formed piece is cut along a plane through a wall thereof to make a finished piece. The finished piece free edge remains stable and in the same position as when in the press. Consequently, the free edge can be readily aligned with and welded to the free edge of a second finished piece.

  • Patent number: 7237414
    Abstract: A coiler drum of a reversing rolling mill includes a work portion that engages a strip of metal being processed in the reversing rolling mill. The work portion includes an inner base surface and engaging strips that extend radially outward from the base surface. When the metal strip is engaged by the work portion, the metal strip does not contact the inner base surface, which has a surface area greater than 35 percent of the work surface. The engaging strips can be formed on the coiler drum by using weld overlays, inserts into slots, or by casting the engaging strips onto the coiler drum at the time the coiler drum is cast. The engaging strips may be laterally offset from one another and have a length less than 50 percent of the axial length of the work portion. The engaging strips may also be formed from a different material than the material of the work surface of the coiler drum.

  • Patent number: 7234656
    Abstract: A paper shredder paper feed mechanism, characterized in having a paper insert opening structured from two movable paper feed tubes, which are configured above paper shredding cutters. Two ends of each of the paper feed tubes are respectively positioned in W-shaped embed grooves of positioning plates of a frame. The two paper feed tubes are ordinarily closed together, thereby enhancing safety and preventing dust and miscellaneous objects from falling into the paper shredder. When paper is inserted into the paper insert opening, the thickness of the paper opens the two paper feed tubes, thereby guiding the paper smoothly guided into the paper shredding cutters.

  • Patent number: 7234333
    Abstract: On a machine for bending rod-shaped or tubular workpieces, which includes a bending head having a bending mandrel mounted on a rotational axis and rotatable by means of a rotary drive, and having a clamping device for pressing the workpiece to be bent against a forming groove on the bending mandrel and also a feeding device for the workpiece to be processed, whereby the clamping device is positionable relative to the bending mandrel and can is also pivotable concentrically to the rotational axis of the bending mandrel, the clamping device is attached to two mutually independent rotary drives, one of which performs its pivoting movement about the rotational axis of the bending mandrel, and via the other of which it can be moved with respect to the bending mandrel by using an interposed conversion transmission that converts a rotary motion to a linear motion, whereby the bending head includes three concentrically nested rotary shafts for transmitting the drive of the three rotary drives to the bending mandrel,

  • Patent number: 7231792
    Abstract: A method and device for manufacturing UOE steel pipes, wherein, when an opening width of the U-can obtained by U-ing press is larger than the die-diameter in an O-press of later step, while said opening is narrowed from the front end by the closing rolls disposed before said O-press and/or at least at the entrance portion of the O-press to be smaller than the die-diameter of said O-press, the U-can is simultaneously conveyed into the O-press, and then, after charging into the O-press, undergoes O-ing press to yield an O-can. The device is preferably configured to have the closing rolls disposed in a roll stand and consisted of multiple pairs, to have a mechanism to prevent the U-can from moving upward during narrowing the opening width, and to have the function of conveying the U-can. Thus, UOE steel pipes for high-strength application corresponding to X80 grade can be efficiently manufactured.

  • Patent number: 7231944
    Abstract: The tension and anti-recoil mechanism of the present invention is connected to a tool handle of a cable tie tool. The tool handle has a barrel and a grip depending therefrom. The tension and anti-recoil mechanism includes a regulator grip supported in the barrel. A one-piece cutter actuator is supported in the regulator grip for longitudinal displacement relative to the barrel. A tension limiting mechanism directs a retaining force against the cutter actuator to resist longitudinal displacement thereof relative to the barrel. The retaining force may be controlled to limit the tension produced in a cable tie prior to severing the strap thereof. Recoil of the cable tie tool which may result from the severing is substantially limited by the tension and anti-recoil mechanism.

  • Patent number: 7228796
    Abstract: Embodiments of subcombination and the fruit extraction device of the present invention provide for fruit juice extraction where synchronized and concentric elements press a fruit, such as an orange, without crushing the peel, by this avoiding the dispersion of acids from the peel, favoring the retention of juice having lower acid levels. Embodiments of the subcombination and the fruit extraction device of which it is a portion shear the peel in multiple slivers, at the same time compressing the fruit. In an exemplary embodiment, a subcombination comprises a fixed and a mobile peeler, each having radially extending blades that form a space within which a fruit may be positioned for juice extraction, and a perforating filtering tube within the fixed peeler, and a piston adapted to pass through the lumen of the perforating filtering tube to cyclically clean it of the residues of a compressed fruit prior to extraction of the next fruit.
