The deburring tool is capable of working tube ends in close quarters. | 03-19-2009 |
| 20110167887 | PIPE CHAMFERING DEVICE - A pipe chamfering device for chamfering an opening of a metal pipe has a secured member, a sliding member mounted on the secured member, and a chamfer cutting tool apron mounted on the sliding member. The secured member is secured onto a rotating plate, and a dovetail block is formed on a front side of the secured member. The sliding member has a dovetail slot on a rear side mounted correspondingly with and sliding along the dovetail block of the secured member. The sliding member has an axial aperture, and an axial rod is disposed in the axial aperture. A front end of the axial rod extends from a front side of the sliding member and is connected to a roller. The chamfer cutting tool apron has a chamfer cutting tool, and the chamfer cutting tool apron is mounted on the strip slot of the sliding member. The chamfer cutting tool is able to be driven by the rotating plate and is capable of forming a weld root with an even thickness at an opening of a non-circular pipe. | 07-14-2011 |
| 20130247635 | METHOD FOR FORMING A PIPE SECTION - The invention relates to a process for forming a pipe portion, in which process a base having an opening and having an inwardly projecting collar is formed. It is provided that the pipe portion is made to rotate, that the pipe portion is drawn in by means of a forming roller, with the base being formed by the drawing-in process, that an inwardly projecting material thickening is formed integrally in the base and that an opening is made in the base in the region of the inwardly projecting material thickening, wherein the inwardly projecting collar is formed by at least part of the inwardly projecting material thickening. Furthermore, the invention relates to an apparatus for forming a workpiece. | 09-26-2013 |

| 20110154875 | PRODUCTION METHOD OF ROTATING DEVICE HAVING THRUST DYNAMIC PRESSURE GENERATING SITE ON WHICH A THRUST PRESSURE PATTERN IS FORMED AND ROTATING DEVICE PRODUCED BY SAID PRODUCTION METHOD - A thrust dynamic pressure pattern is marked on a rotating member or fixed member set on a rest table. A pressure for marking is applied to a member to be marked in a cycle of applying and releasing the pressure, and a supplemental force for keeping the member to be marked, still is separately applied. According to the present embodiment, a rotating device can be provided that narrows down a bearing gap and improves the efficiency of raking up a lubricant so as to increase the dynamic pressure by reducing the deformation of the shape of the protrusions of a thrust dynamic pressure pattern and the variation in the height of the protrusions when forming the thrust dynamic pressure pattern in a method of producing a rotating device. | 06-30-2011 |
| 20110296888 | FLANGE-FORMING SYSTEM FOR TUBE AND RELATED METHODS - A system is configured for forming a flange at an end of a tube. The system includes a collar configured to receive the tube. A first roller engages the collar and a second roller is configured to cooperate with the first roller to rotate the collar and the tube. A rotatable cam is disposed about the second roller and includes a cam surface configured to bend the end of the tube to thereby form the flange. The collar may be configured to restrict axial movement of the tube relative to the collar. Additionally or alternatively, the collar may be configured to restrict rotational movement of the tube relative to the collar. | 12-08-2011 |
| 20140196515 | Apparatus and Method for Forming a Screw Flight - This invention relates to an apparatus for forming a helical screw flight from a flight blank. The apparatus includes a base and an engaging means. The engaging means is movably mounted to the base and is configured to formingly engage the blank so as to form a twist in at least a portion of the flight blank corresponding to a predetermined pitch of the flight. | 07-17-2014 |
| 20150013415 | Tool for the Chipless Production or Finishing of a Thread on a Workpiece, in particular Cold-forming Tap or Thread-forming Tap - A tool for the chipless production of a thread on a workpiece can comprise a forming region, which is rotatable about a tool axis (A), for the chipless production of an internal thread, wherein the forming region has a plurality of pressure studs, which project radially from the tool axis (A), for producing or finishing the thread by pressing the pressure studs into the workpiece surface. In one implementation, the pressure studs are arranged successively along a shaping curve that encircles the tool axis (A) in a substantially spiral manner, and the pitch of the shaping curve corresponds substantially to the pitch of the thread to be produced. Additionally, the pitch angle (t1) between first and second pressure studs along the shaping curve differs from the pitch angle (t2) between the second pressure stud and a third pressure stud that follows the second pressure stud along the shaping curve. | 01-15-2015 |
