| 20090078017 | Roll grooving apparatus - A roll grooving apparatus has a back-up roller, a grooving roller positioned vertically below the back-up roller, and a hydraulic jack positioned directly vertically below the grooving roller, with the hydraulic jack exerting an upward force to push the grooving roller towards the back-up roller to form a circumferential groove in a pipe segment that is positioned between the rollers. | 03-26-2009 |
| 20090193866 | Minimizing circumferential transition lines during container shaping operations - The invention provides a method of designing shaping tools for metal containers (such as metal bottles) to minimize the formation of visible transition lines or ripples conventionally produced in such procedures as die necking and outward flaring. The method involves carefully measuring differences between an actual shape produced and a design shape resulting from an original set of shaping tools. The tools are then refined in design to take into account metal spring back and the effect of one shaping stage on the results of previous stages. The redesign goes through several iterations to ensure that each change produces an improvement of the formed container. In this way, the formation of transition lines can be minimized because the actual shape of the container more closely resembles the smooth design shape. Dies designed in this way are then used for commercial shaping operations. | 08-06-2009 |
| 20090217725 | FLOW FORMED SPLINE AND DESIGN SUITABLE FOR BURR FREE MACHINING - A method and tool for producing a flow formed part are disclosed, wherein the tool has an annular array of spline forming recesses for producing a flow formed part having splines and machining and production costs are minimized and efficiency is maximized. | 09-03-2009 |
| 20130014554 | CRAFT BEAD ROLLERAANM Dehne; Vicki L.AACI Bel AirAAST MDAACO USAAGP Dehne; Vicki L. Bel Air MD US - A bead roller is provided for manually crafting a bead from a strip of material. The bead roller may include a handle guide carrier, a first handle portion mounted for rotational movement on the handle guide carrier; a second handle portion mounted for rotational and longitudinal movement on the handle guide carrier; and a tool arm axially extending from the second handle portion and having first and second spaced apart opposing edges which define a slot which receives and engages a distal end of the strip of material. The second handle portion is configured for rotation simultaneously with the tool arm about the handle guide carrier and independently of the first handle portion. | 01-17-2013 |
| 20160059293 | Roller For Roll Forming - A roller for engaging an outer surface of a pipe element during roll forming has a perimeter region defined by three faces. A channel is positioned in one of the faces. The channel extends circumferentially around the perimeter region and provides a void space that reduces the contact area between the face and the side surface of a circumferential groove formed in the pipe element during roll forming. The reduced contact area reduces frictional heating of the pipe and roller as well as the tendency of the roller to slip relative to the floor surface of the groove due to axial force engendered when an asymmetrical groove is formed. | 03-03-2016 |
| 20160375478 | PIPE GROOVING DEVICE - A pipe grooving tool that works with commercially-available power drives. The tool attaches to the power drive using the existing tool assembly on the power drive, and allows a single operator to cut, ream and groove multiple pipe segments, without having to replace tools or otherwise alter the power drive and its tool assembly between grooving different pipe segments. | 12-29-2016 |
| 072106000 | And circumferentially spaced, work-engaging elements | 2 |
| 20090113971 | RING MILL APPARATUS AND METHOD - A ring mill apparatus and method utilizes at least one hydraulic or other direct drive motor to drive a roller in contact with a ring that is to be expanded by the ring mill. The motor may be two opposed radial piston hydraulic motors, to drive an upper king roller, which contacts the outside of the ring, which is inserted between the upper king roller and a lower mandrel roller, which contacts the inside of the ring. The lower mandrel roller is urged upwards against the ring by a ram driven carriage. Two hydraulic or other direct drive motors can be provided in-line with, and directly connected to, the king roller. | 05-07-2009 |

The ring rolling process makes use of a ring rolling machine. The ring rolling machine includes a main roll which presses a circumferential outer surface of a blank, a pressure roll which presses a circumferential inner surface of the blank, and a pair of axial rolls which press upper and lower surfaces of the blank. The method includes expanding an inner diameter and outer diameter of the blank using the ring rolling machine, transferring the pressure roll vertically so that a protrusion provided on a circumferential outer surface of the pressure roll comes into contact with the circumferential inner surface of the blank, and forming a depression in the circumferential inner surface of the blank using the protrusion of the pressure roll. | 08-15-2013 |

Each gear unit has a rolling portion, a rolling shaft extends from the rolling portion, a clicking column and two location columns extend from edges of a free end of the rolling shaft along an axle direction of the rolling shaft. The clicking column and the two location columns are spaced out from each other to form three grooves therebetween, a clicking clasp extends inward from the top of the clicking column. The clicking clasp has an inclined inner surface which inclines inward from top to bottom. The two rolling shafts are inserted into the hole of the base, the clicking column of one of the rolling shafts mates the groove opened between the location columns of the other rolling shaft, the location columns of one of the rolling shafts mate the grooves opened between the clicking column and the location columns of the other rolling shaft respectively, bottom surfaces of the two clicking clasps are against each other. | 02-19-2009 |
