61 | Flow-turning device and method for producing internally geared wheels using two sets of internal toothing | US09424744 | 2000-03-31 | US06253589B1 | 2001-07-03 | Karl Heinz Putz; Bernd Stein; Heinz Steinhauer; Wilhelm Zimmermann |
The invention relates to a flowturning device (1; 101) for producing an internal geared wheel (17) with inner toothing, one set of which is slanted. The workpiece (9) is held by a retaining member (16; 116) during shaping of the first inner toothing. The workpiece (9) is held by the first toothing on the first shaping toot (2; 102) during shaping of the second inner toothing. Once the internal geared wheel (17) has been finished, the rotational coupling between both shaping tools (2, 4; 102, 104) is detached. The internal geared wheel (17) is detached from the slanted toothing(s) by means of a stripping member (18). | ||||||
62 | Tap employing deformation of matter | US936551 | 1997-09-24 | US5937684A | 1999-08-17 | Jean-Fran.cedilla.ois Long |
This invention relates to a tap employing deformation of matter, wherein it comprises a body which bears three rotating cylinders mounted idly and provided with annular threads each distant by the value of the pitch of the threading to be made. These three cylinders are regularly distributed and are inclined axially by an angle equal to the helix angle of the thread to be made. | ||||||
63 | Method for forming an internal thread in a hollow body | US540550 | 1983-10-03 | US4527299A | 1985-07-09 | Torben Bredal |
To manufacture a nut, a piece of plate material is bent to form a tube (9) which is placed over a mandrel (8) and clamped together around the mandrel, first by means of a pair of spring-loaded dowels (5) and thereafter by two clamping jaws 1, 2. The mandrel is then withdrawn, and a thread-forming tap (12) rotating in the direction of the thread is pressed in through the tube to produce an internal thread by deformation. When the tap has passed through the tube, the direction of rotation is reversed and the tap is screwed out again, after which the nut is finished. For cooling and lubrication, cutting oil is supplied to the tap before insertion into the tube and possibly to the inside of the tube. Alternatively, a tap with a shank (13) which functions as the mandrel (8) and has a threading piece (14) at one end can be used. After sliding the slotted tube onto the shank, the thread is formed when the tap is turned out of the tube, thereby avoiding having to turn the tap through the tube more than once. | ||||||
64 | Method and apparatus for forming internal threads in tubes | US363316 | 1982-03-29 | US4457153A | 1984-07-03 | John X. Russell |
A method and apparatus for forming internal threads on tubular components by a non-cutting process is disclosed. Various disclosed features find particular utility when using a thread forming or rolling tap process to form internal threads on sucker rod coupling tubes. In the preferred embodiment, a machine is disclosed utilizing a movable fixture head (34) capable of simultaneously threading one or more tubes (12, 12') of various sizes. A single hydraulic cylinder (59) moves the fixture head to various positions relative to the work stations (14, 16) to control several operational steps including the sequential feed of the tubes (12) to the work stations (14, 16), clamping/unclamping of the tubes during the tapping process, and retention of the tap (204) while the threaded tubes are removed from the work stations. | ||||||

The tool holder of the present invention is of simple construction and confers an economy of processing. | ||||||
66 | Apparatus for shaping hollow metal bodies | US46391574 | 1974-04-25 | US3924434A | 1975-12-09 | FULIER JOSEF |
Apparatus for shaping hollow metal bodies such as hollow rivets and the like on a mandrel including a hollow supporting sleeve adapted to receive the body and the mandrel. At least two forming bodies located in openings in the wall of the supporting sleeve, symmetrically with respect to the longitudinal axis of the sleeve. The forming bodies such as freely rotating balls or rollers with their external circumference against a pressure element surrounding at least in part the supporting sleeve and biasing the forming bodies against the surface of the hollow body.

67 | Method of making internal shapes in metal objects having smooth or toothed rotational outer surfaces | US30991172 | 1972-11-27 | US3866450A | 1975-02-18 | MARCINIAK ZDZISLAW; KOPACZ ZEONON |
A method of shaping a plastically deformable sleeve by rolling jaws, having an internal shaping surface, on the sleeve after a shaping core has been placed in the bore of the sleeve. As a result of the rolling operation, the outer diameter of the material is reduced and the inner surface of the sleeve assumes the external shape of the core. The method enables simultaneous shaping of the outer and inner surface of the sleeve such as an outer toothing and a splined bore. In a particular embodiment in which internal threads are to be formed on the sleeve, an unrevolving core is used which is elastically biassed against axial displacement so that when the sleeve is rotated by the jaws in the course of shaping the core will be axially displaced against the elastic biassing action and the core will automatically advance over an axial feed distance when the jaws release the sleeve.

There is provided an R-¸ table apparatus which freely moves one table on a plane in the forward-and-rearward and leftward-and-rightward directions and in the rotational direction. The apparatus includes: a table which is provided with a through hole having a bearing; a guide member which holds the table to be horizontally freely movable; a driving apparatus which is provided with an action axis inserted being inclined to the bearing, and drives the action axis to be freely rotated and stopped; an elevating base which elevates the driving apparatus; an elevating apparatus which elevates the elevating base, and changes a position of an action point at which the action axis and the bearing are engaged with each other; and a base which is provided with a post that guides the elevating base and the guide member, and mounts the elevating apparatus, in which a horizontal distance between a center line of a main axis of the driving apparatus and the action point is changed by elevating the elevating base, and the table is moved to an arbitrary position without rotating along the guide member. | ||||||
