| 21 | Rolleisen zum Drücken von Gewinde | EP93100724.9 | 1993-01-19 | EP0552713A1 | 1993-07-28 | Glimpel, Helmut, Dipl.-Ing.; Maier, Dietmar |
Es gibt ein Rolleisen, bei dem ein Grundkörper 1 zum Gewindedrücken Profilrollen 9 trägt, die beim Grundkörper 1 jeweils gegen einem axial positionierenden Anschlag 6, 7, 8 gelegt und mit den freien Enden 10 entsprechend der Steigung des zu drückenden Gewindes in Achsrichtung versetzt sind. Dabei ist es erwünscht, wenn der axiale Versatz der freien Enden der Profilrollen durch gleiche Ausbildung sämtlicher Profilrollen in einer weniger aufwendigen Weise erreicht ist. Es ist eine wesentliche Voraussetzung geschaffen, um das Rolleisen hin zu einem Einwegwerkzeug zu entwickeln. |

| Pour la fabrication d'un écrou, on peut utiliser une pièce d'un matériau en forme de plaque qui est pliée pour former un tube (9). Ce tube peut être placé sur un mandrin (8) et bridé autour du mandrin, d'abord à l'aide d'une paire de goujons armés d'un ressort (5) puis par deux mâchoires de bridage (1, 2). Lorsque le mandrin est ensuite retiré, un taraud (12) de formation d'un filetage, pendant la rotation dans le sens du filet, peut être pressé dans le tube pour produire, en passant au travers de ce dernier, un filetage intérieur par déformation. Lorsque le taraud est passé au travers de tout le tube, le sens de rotation est inversé et le taraud est dévissé, et l'écrou est fini. Pour la lubrification et le refroidissement, de l'huile d'usinage est amenée sur le taraud avant l'introduction dans le tube et éventuellement à l'intérieur du tube. On peut également utiliser un taraud ayant une queue (13) qui sert de mandrin (8), et à l'extrémité de laquelle s'étend la pièce de filetage (14). De cette manière le filet est formé lorsque l'on fait tourner le taraud dans le sens contraire à la direction du filet, c-à-d en sortant du tube par rotation, éliminant ainsi le besoin d'introduire le taraud au travers du tube plus d'une fois. | ||||||

| In order to optimize a nut and a method for the production of a nut, comprising a nut body which is provided or can be provided with an internal thread and has a polygonal section with a polygonal outer contour which has, on the one hand, edge areas and, on the other hand, key faces which are located between the edge areas and extend in key face planes extending in a manner conforming to standards, in such a manner that it has mechanical properties which are as ideal as possible with as low a weight as possible, it is suggested that the nut body have a plurality of recesses which extend into the nut body in the direction of the bore proceeding from the respective key face planes. | ||||||
| 25 | SCREW THREAD ROLLER BURNISHING APPARATUS | US14770925 | 2014-01-07 | US20160008949A1 | 2016-01-14 | Thomas R. McMillian |
| Internal and external screw thread burnishing assemblies are provided. In the internal screw thread burnishing assembly, diametrically opposed removable cartridges carrying burnishing wheels are received in cavities of a support structure axially movable into the space circumscribed by the internal screw thread. Fluid pressure is utilized to forcibly translate the cartridges radially outwardly to place their burnishing wheels into burnishing engagement with the internal screw thread, with a spring structure resiliently biasing the cartridges toward retracted orientations thereof within the support structure. In the external screw thread burnishing assembly, burnishing wheels are carried on the outer ends of pivotally supported arms which may be pivoted by fluid pressure to drive the burnishing wheels into burnishing engagement with diametrically opposite portions of the external screw thread, with a spring structure resiliently biasing the arms pivotally away from one another. | ||||||

| When processing a female screw in a hole of a metallic material having the hole for female screw processing, a method includes forming a screw groove by sequentially pressing a processing portion of a male screw-shaped tool against an inner periphery of the hole only by a motion of a revolution of the male screw-shaped tool on a certain horizontal plane without rotation by itself in the state of gripping or fixing the metallic material to transfer a shape of the processing portion. | ||||||
| 27 | SCREW OR NUT WITH A THREAD A PITCH OF WHICH VARIES AND TOOL TO PRODUCE SAID SCREW OR NUT | US13146195 | 2010-01-19 | US20110280683A1 | 2011-11-17 | Joachim Galipaud |
| The distribution of load stresses on threads engaged with a standard screw or nut is very unequal. Indeed, the first threads in engagement support a large majority of the load. So if the load is too important, the threads give way and the function is not provided any more by the screw or the nut. In the prior art, threads are known whose depth or pitch varies a lot in order to cause a self-clamping. In particular, the invention aims at optimizing the resistance and the fatigue resistance of the screws by distributing the load at the very best on their threads without causing this self-clamping. It was shown that the control of the pitch variation, within a chosen pitch tolerance, makes it possible to control the stress distribution on the threads. It is possible to determine a different variation for each load case encountered. | ||||||

| The invention relates to a device (101) to provide helical rotating projection of a thread-forming thread core (102).According to the invention, internally in a cylindrical space (103) of a fluid cylinder-piston device (104), there is arranged a movably actuatable piston (105) provided with a number of helical holes (106). In that connection, a helical (109) shaft (108) shape-adapted to the respective hole (106) and helix (107) is receivable in said respective helical hole (106), and that the respective shaft (108) is, via a gear (110), connected with a mechanism (111) for the transmission of rotating (112) as well as axial (113) displacement motion to said thread-formed thread core (102). Finally, a stop member (114), which is arranged to limit the displacement motion (115) of the piston, is arranged internally in the cylinder space (103) of said piston cylinder. | ||||||

| An apparatus for working a surface of a metal pipe is provided. The apparatus comprises a drawing unit for drawing a metal pipe to reduce a diameter thereof, and a working assembly for working the diameter-reduced metal pipe to form an inner surface and/or an outer surface thereof into a predetermined configuration. The working assembly includes a rolling unit and a driving mechanism therefor. The rolling unit includes a housing, a plurality of rolling rolls rotatably disposed within the housing and outside the metal pipe so that the rolling rolls have their respective axes extending at an inclination angle with respect to an axis of the metal pipe. The rolling rolls are respectively mounted on support shafts rotatably supported in the housing through thrust bearings. The driving mechanism drivingly rotates the rolling unit to revolve the rolling rolls around the metal pipe. The rolling unit is removably mounted on the driving mechanism. | ||||||
| 32 | Method of making plug-containing type internally threaded anchor | US815597 | 1985-12-31 | US4653132A | 1987-03-31 | Takao Yamada |
| The present invention relates to a plug-containing type internally threaded anchor to be set in concrete which is used to optionally and firmly fix hardware, such as ceiling members, floor members and wall members, to the surface of a concrete structure and it also relates to a method of producing the same which promises mass-production effect. The invention is characterized in that as a means for preventing the plug contained in the anchor body from accidentally slipping off owing to vibration, shock or other external forces exerted during transport or laying operation, the anchor body is formed with an internal thread by rolling whose internal diameter is smaller than the outer diameter of the plug, so that the crest portion of the internal thread bulging by a predetermined amount above the anchor body holds the plug in slip-off preventing condition. | ||||||
